DESCRIPTION
Mined is a text editor with

  Good interactive features

    •   Intuitive user interface

    •   Logical and consistent concept of navigating and editing text (without ancient line-end handling limitations or insert/append confusion)

    •   Supports various control styles:

        •   Editing with command control, function key control, or menu control

        •   Navigation by cursor keys, control keys, mouse or scrollbar

    •   Concise and comprehensive menus (driven by keyboard or mouse)

    •   "HOP" key paradigm doubles the number of navigation functions that can be most easily reached and remembered by intuitively amplifying the associated function

    •   Immediate adjustment if the window size is changed, in any state of interaction

  Versatile character encoding support

    •   Extensive Unicode support, including double-width and combining characters, script highlighting, various methods of character input support (mapped keyboard input methods, mnemonic and numeric input), supporting CJK, Vietnamese, Hebrew, Arabic, and other scripts

    •   Extensive accented character input support, including multiple accent prefix keys.

    •   Support for Greek (monotonic and polytonic).

    •   Support for Cyrillic accented characters.

    •   Support of bidirectional terminals, Arabic ligature joining

    •   East Asian character set support: handling of major CJK encodings (including GB18030 and full EUC-JP with combining characters)

    •   Support for a large number of 8 bit encodings (with combining characters for Vietnamese, Thai, Arabic, Hebrew)

    •   Support of CJK input methods by enhanced keyboard mapping including multiple choice mappings (handled by a pick list menu); characters in the pick list being sorted by relevance of Unicode ranges

    •   Han character information with description and pronunciation

    •   Auto-detection of text character encoding, edits files with mixed character encoding sections (e.g. mailboxes), transparent handling and auto-detection of UTF-16 encoded files

    •   Auto-detection of UTF-8 / CJK / 8 bit terminal mode and detailed features (like different Unicode width and combining data versions)

    •   Comprehensive and flexible (though standard-conformant) set of mechanisms to specify both text and terminal encodings with useful precedences.

    •   Flexible combination of any text encoding with any terminal encoding.

    •   Encoding support tested with: xterm, mlterm, rxvt, cxterm, kterm, hanterm, KDE konsole, gnome-terminal, Linux console, cygwin console, MinTTY, PuTTY

  Many useful text editing capabilities

    •   Many text editing features, e.g. paragraph wrapping, auto-indentation and back-tab, smart quotes (with quotation marks style selection and auto-detection) and smart dashes

    •   Search and replacement patterns can have multiple lines

    •   Cross-session paste buffer (copy/paste between multiple - even subsequent or remote - invocations of mined)

    •   Optional Unicode paste buffer mode with implicit conversion

    •   Marker stack for quick return to previous text positions

    •   Multiple paste buffers (emacs-style)

    •   Program editing features, HTML support and syntax highlighting, identifier and function definition search, also across files; structure input support

    •   Text and program layout features; auto-indentation and undent function (back-tab), numbered item justification

    •   Systematic text and file handling safety, avoiding loss of data

    •   Visible indications of special text contents (TAB characters, different line-end types, character codes that cannot be displayed in the current mode)

    •   Full binary transparent editing with visible indications (illegal UTF-8 or CJK, mixed line end types, NUL characters, ...)

    •   Print function that works in all text encodings

    •   Optional password hiding

    •   Optional emacs command mode

  Small-footprint operation and portability

    •   Plain text mode (terminal) operation, supporting wide range of terminals

    •   Instant start-up

    •   Runs on many platforms: Unix (Linux/Sun/HP/BSD/Mac and more), DOS (djgpp), Windows (cygwin, Interix)

    •   Makefiles also support legacy systems

Command line options
Mined can be invoked

    •   with or without list of file names

    •   reading from a pipe (reading text from standard input)

    •   writing into a pipe (writing edited text to standard output)

    •   using a script that starts it in a new window

  Examples

mined x
    edits the file x

mined x y z
    edits files x, y, and z

cmd | mined
    edits the output of program cmd; a file name for saving can be given later

mined x > y
    takes the contents of file x and edits it for writing into y

mined | mail nn
    edits a text to be mailed

cmd1 | mined | cmd2
    modifies text within a pipe between program cmd1 (output) and cmd2 (as input)

minmacs ...
    runs mined in emacs-compatible command mode (like mined -e)

mstar ...
    runs mined in WordStar-compatible command mode (like mined -W)

mpico ...
    runs mined in pico-compatible command mode (alpha)

xmined ...
    starts a new terminal window (xterm or rxvt, depending on current TERM variable setting) and invokes mined in it

umined ...
    starts a new terminal window in UTF-8 mode (xterm or rxvt, depending on font availability and usage capabilities) and invokes mined in it

wmined ...
    (on Windows) starts a new rxvt terminal in stand-alone mode (i.e. without needing X windows), using Windows look-and-feel, and invokes mined in it; the terminal is configured to run in UTF-8 mode which may work with a future version of rxvt (currently ignored)

  Startup options

+number
    Mined positions to the given line number.

+/expr
    Mined initially searches for the given search expression.

-v  Mined starts in view only mode. The text cannot be modified.

--  Restricted mode (tool mode): no other files can be edited or otherwise affected.

++  End of options; subsequent file name can start with "-" or "+".

+x  Make new files executable (Unix). →NEW→ When cloning a file (with Save As or a similar feature), or if permissions are restricted by the environment (umask setting in Unix), executable permission is set only where also read permission is set.

  Line end handling (transparent and transforming)

-r  Convert MSDOS line ends (CR LF) to Unix line ends (LF) (stripping CR at line ends). Can be combined with -R →NEW→ or +R. Also sets line end type for new files to LF for the djgpp version (which defaults to CR LF).

+r  →NEW→ Convert Unix line ends (LF) to MSDOS line ends (CR LF) (adding CR at line ends). Can be combined with -R or +R. Also sets line end type for new files to CR LF.

-R  Convert Mac line ends (CR) to Unix line ends (LF). →NEW→ Can be combined with -r or +r.

+R  Recognise Mac line ends (CR) and indicate them on display; nothing is transformed with this option. →NEW→ Can be combined with -r or +r.

+u-u
    Interpret Unicode line separator and paragraph separator as normal characters, not line ends (handling them as line ends was previously enabled with -uu and is now on by default).

  Character set and character handling

-u	(character set)
    Interprets edited text as UTF-8, disables UTF and CJK auto detection.
    Synonym of -EU.

-l	(character set)
    Interprets edited text as Latin-1, disables UTF and CJK auto detection. (Used to be +u which is still valid for compatibility.)
    Synonym of -EL.

+u-u	(character handling)
    Interpret text as UTF-8, but interpret Unicode line separator and paragraph separator as normal characters, not line ends.

-c	(character handling)
    Selects separated display mode for combined characters (separating base character and combining characters). This mode can also be toggled from the Options menu or by clicking on the Combining flag (next to the character encoding flag) in the flags area.

-b	(character handling)
    Toggle "poor man's bidi" mode: input support for right-to-left scripts, based on Unicode script ranges. (Enabled by default unless the terminal is detected to be in bidi mode; so e.g. in mlterm, poor man's bidi is disabled by default.)

-EX	(character set)
    Where X is one of B/G/C/J/S/K/H: Selects one of the supported CJK character encodings for text interpretation and disables auto-detection of CJK encodings. For details, see CJK encoding support. For more details on supported encodings, see the Character encoding flags listing in the Mode indication flags section.

-EX	(character set)
    Where X is one of U/L or another 1-letter character encoding tag: Selects Unicode/UTF-8, Latin-1, or one of the other supported character encodings for text interpretation. For details on supported encodings, see the Mode indication flags listing.

-E=charmap	(character set)
    Where charmap is a character encoding name (as reported by the locale charmap command): Selects the respective character encoding for text interpretation. For details on locale-related character encoding configuration, see Locale configuration.

-E.suffix	(character set)
    Where suffix is a character encoding suffix ("codeset") as used in locale names: Selects the respective character encoding for text interpretation. For details on locale-related character encoding configuration, see Locale configuration.

-E:flag	(character set)
    Where flag is a 2-letter indication used by mined to indicate the respective text encoding in the Encoding flag: Selects the respective character encoding for text interpretation. For details on supported encodings and their flags, see the Mode indication flags listing.

-Eu	(buffer encoding)
    Enables Unicode buffer mode which always maintains the Copy/Paste buffer in Unicode, thus facilitating conversion between different encodings being edited. For details, see Unicode Copy/Paste buffer conversion.

-E?	(character set)
    →NEW→ Determine the encoding(s) of the text file(s) given as parameters by auto-detection, print out the information and quit.

-KX	(input method handling)
    Configure the Space key to perform a certain function in keyboard mapping selection menus ("CJK input method pick lists"), where X is one of:
     'n' to navigate to the next choice (like cursor-right),
     'r' to navigate to the next row (like cursor-down),
     's' to select the current choice (like Enter).

-K=im-im	(input method selection)
    →NEW→ Select input method and/or standby input method (for quick switching with Alt-k). The syntax is the same as for the optional environment variable MINEDKEYMAP (see below).

+K	(input method handling)
    (Obsolete with 2000.15 since keyboard mapping is always enabled by default.) Enable keyboard mappings (input methods) even in 8-bit terminal or when editing an 8-bit encoded file; the characters thus entered will mostly only be displayed by substitute indications (as most characters anyway when editing files in an 8-bit terminal not matching the character set).

  Terminal mode

-U	(terminal mode)
    Toggles UTF-8 screen handling assumption, i.e. selects UTF-8 screen handling unless UTF-8 keyboard input is already selected (by another -U option or environment setting). In the latter case, -U deselects UTF-8 terminal operation. This option should normally not be used as the mode should be configured in the environment (see Locale configuration).

+U	(terminal mode)
    Selects UTF-8 screen handling. Note that none of the options -U or +U needs to be used if the environment is correctly configured to indicate UTF-8 as it should (see Unicode handling / Terminal environment).
    Also, mined performs auto-detection of UTF-8 terminal encoding and UTF-8 terminal features (different width data versions, handling of double-width, combining and joining characters), so even if the environment is not correctly configured, mined should work without this explicit terminal mode parameter.

+UU	(terminal mode)
    Selects bidirectional terminal support. This mode implies UTF-8 and also assumes that Arabic ligature joining (of LAM/ALEF combinations) is applied; it will be handled by mined accordingly.

-cc	(terminal mode)
    Assumes that the terminal does not support combining characters. By default - unless otherwise detected - mined assumes that combining characters work on UTF-8 terminals and do not work in CJK terminals.

+c	(terminal mode)
    Assumes that the terminal supports combining characters. This is enabled by default for UTF-8 terminals, and disabled by default for CJK terminals, unless otherwise detected.

+EX	(terminal mode)
    Where X is one of B/G/C/J/S/K/H: Assumes a CJK encoded terminal in one of the supported CJK character encodings. For details, see CJK encoding support.

+EX	(terminal mode)
    Where X is one of g/c/j: Assumes a CJK encoded terminal in one of the CJK character encodings like G/C/J and also assumes that the terminal cannot display GB18030 4-byte encodings, CNS 4-byte encodings, EUC-JP 3-byte encodings, respectively.

+EX	(terminal mode)
    Where X is one of U/L or another 1-letter character encoding tag: Assumes a Unicode/UTF-8 or Latin-1 encoded terminal, respectively, or an 8-bit terminal running one of the other supported character encodings. For details on supported encodings, see the Mode indication flags listing. For details on terminal encoding support, see Terminal encoding support.

+E=charmap	(terminal mode)
    Where charmap is a character encoding name (as reported by the locale charmap command): Assumes the terminal to have the respective encoding. For details on locale-related character encoding configuration, see Locale configuration.

+E.suffix	(terminal mode)
    Where suffix is a character encoding suffix ("codeset") as used in locale names: Assumes the terminal to have the respective encoding. For details on locale-related character encoding configuration, see Locale configuration.

+E:flag	(terminal mode)
    Where flag is a 2-letter indication used by mined to indicate the respective encoding as text encoding in the Encoding flag: Assumes the terminal to have the respective encoding. For details on supported encodings and their flags, see the Mode indication flags listing.

+E?	(terminal mode)
    →NEW→ Determine the terminal encoding and further terminal encoding features and properties by auto-detection, print out the information and quit.

-C	(character set and terminal mode)
    (Deprecated.) Turns a subsequent -E option (with a single-letter CJK tag) effectively into a combined -E and +E option. So mined assumes the given CJK encoding for both terminal encoding (unless overridden by UTF-8 terminal auto-detection) and text encoding. Can be used for quick indication of CJK terminals (e.g. cxterm, kterm, hanterm) if locale environment is not properly set.

+C	(terminal mode)
    Displays unknown characters on CJK terminal: Assumes a CJK encoded terminal (e.g. cxterm, kterm, hanterm; more specific encoding specification is advisable), and characters encoded in a CJK encoding format are displayed transparently even if they do not map to a valid Unicode character.

+CC	(terminal mode)
    Displays invalid characters on CJK terminal: Implies +C, but even character codes that do not match the encoding scheme (e.g. wrt. to specified byte ranges) are written transparently to the terminal.

+CCC	(terminal mode)
    Displays extended characters on CJK terminal: Implies +CC and overrides auto-detection of the terminal capability to display CJK 3-byte / 4-byte codes which would by default suppress their display if the terminal does not support them.

+D	(keyboard assignment)
    Setup xterm (by sending dynamic configuration codes) to apply two useful keyboard handling modes: Del key on small keypad sends DEL character rather than an escape sequence and can thus be distinguished from the Del key on the big (numeric) keypad. Prepend ESC to character if pressed with the Alt or Meta key in order to enable Alt-commands (e.g. Alt-f to open the file menu, Alt-Shift-H to enter HTML markers etc). (Unfortunately this cannot be done by default as it cannot be undone because the previous state cannot be detected.) (This xterm setting should rather be configured permanently as suggested in the sample file Xdefaults.mined in the Mined runtime support library.)

  Information display

+?c →NEW→ Enable character code information display on status line.

+?X →NEW→ Enable character code information display (implies +?c) with additional information, where X is one of:

    •   s: Unicode script

    •   n: Unicode character name

    •   d: Unicode character decomposition

    •   m: mined input mnemonics available for this character
Note: setting any of these options may disable some others as not all combinations are considered useful.

+?h →NEW→ Enable full Han character information display as a popup. In addition to the character description, a set of pronunciations can be selected with the variable MINEDHANINFO.

+?x →NEW→ Enable compact Han character information on status line. In addition to the character description, a set of pronunciations can be selected with the variable MINEDHANINFO.

+?f →NEW→ Enable file and position information display on status line. (On by default since mined 2000.15.) Note that when editing a file that does not fit completely in memory (e.g. large file on old system), this option may cause considerable swapping. In that case, disable the feature with -?f.

-?X →NEW→ Deselect the respective +? option.

  Editing behaviour

-w  Recognise fewer places as word boundaries for word skip and delete commands.

-a  Append mode: Append to text buffer or external file for copy/delete commands instead of replacing it.

+j  Set justification level 1 (or increment level previously set by environment variable to 1 or 2): Level 1 initially enables automatic word wrap at line end when typing over right margin. Can be changed by clicking on the j/J flag.

+jj Set justification level 2: Level 2 initially enables automatic word wrap at line end when typing within paragraph; buggy. Can be changed by clicking on the j/J flag.

-j  Set justification level 1 or 2 (other than previously set). Can be changed by clicking on the j/J flag.

-T  When moving vertically over a Tab character, stay →NEW→ left of the Tab column range (on the Tab character). The default depends on the previous position. Also, stay left on a wide character when moving vertically over it.

+T  →NEW→ When moving vertically over a Tab character, stay right of the Tab column range (behind the Tab character). The default depends on the previous position.

  Appearance

-QX Select menu border style, where X is one of

    •   s: simple border,

    •   r: rounded corners,

    •   f: fat border,

    •   d: double border,

    •   a: ASCII border (can be combined with another option -Qs or -Qr),

    •   v: VT100 alternate character set graphics border,

    •   @: reverse blank border (deprecated),

    •   1: (or another digit) add a margin between menu borders and contents (can be combined with any other -Q option),

    •   Q: stylish selection bar for navigating menu items, see image (can be combined with another option -Qs or -Qr or -Qf or -Qd).

    •   q: disable stylish selection bar
Mined sets an appropriate default based on its assumptions of the terminal capabilities.

-O  →NEW→ Disable script colour highlighting (for Greek, Cyrillic...).

+O  →NEW→ Enable script colour highlighting (for Greek, Cyrillic...). (Disabled by default in dark terminals.)

-f  Restrict usage of graphic characters: use cell-grained scrollbar, simple menu borders, no fancy menu bar for highlighting the selected menu item.

-ff Further restrict usage of graphic characters: no Unicode box drawing graphic characters for menu borders.

-fff
    Further restrict usage of graphic characters: no graphic characters (including VT100 block graphics) for menu borders.

-F  Assume a screen font with limited coverage of special symbols and restrict usage of special marker characters for display of line indications. (This is needed e.g. for KDE konsole or for xterm using TrueType fonts.)
    Interpretation of the MINEDUTF* environment variables is suppressed.

-FF Assume a screen font with even more limited coverage of special symbols and restrict usage of special characters for indication of selected menu items.

+F  →NEW→ Revert the effect of one -F option (e.g. preconfigured in the environment variable MINED) or a corresponding assumption of mined about the specific terminal which would limit font usage.

+FF →NEW→ Fully enable usage of characters for special indications.

  Further mode selection, interface and display behaviour

-4  Set Tab size to 4 rather than 8. The effective Tab size can also be toggled while editing with the ESC T command.

-8  Set Tab size to 8. (May be used on command line to override Tab size being set to 4 be MINED environment variable.) The effective Tab size can also be toggled while editing with the ESC T command.

-+4 Set spacing Tab with size 4; a Tab input character will be expanded to an appropriate number of spaces. To enter a real Tab character, type Ctrl-V Tab (^V^I). The effective Tab size can also be toggled while editing with the ESC T command. Tab expansion mode can also be toggled while editing with the HOP ESC T command.

-+8 Set spacing Tab with size 8; a Tab input character will be expanded to an appropriate number of spaces. To enter a real Tab character, type Ctrl-V Tab (^V^I). The effective Tab size can also be toggled while editing with the ESC T command. Tab expansion mode can also be toggled while editing with the HOP ESC T command.

-P  Hide passwords; enables hidden display of one word behind the string "assword" in a line (to accommodate for "password" or "Password"): hidden characters are indicated by reverse "*" characters. By default, this mode is activated when editing a file whose name starts with ".".

+P  Unhide passwords; always display them.

-LN (N is a number) Define mouse wheel movement to scroll by N lines (default 3). Ctrl-mouse-wheel always scrolls by 1 line. Shift-mouse-wheel scrolls by 1 page. →NEW→ Mouse-wheel on the scrollbar scrolls by half a page.

-e  Select emacs mode. This assigns functions to control keys, M-X commands (ESC commands, using the "meta" key as emacs calls the Alt prefix) and C-X commands as defined by the emacs editor. Also the emacs paste buffer ring and cut/paste behaviour is enabled.

-V  Place cursor before pasted region after paste commands. (If this option is enabled already, -V acts like -VV.)

-VV Like -V, and disable emacs-style paste buffer functions for "delete word" and "delete to end of line" commands (^T, ^K).

+V  Place cursor behind pasted region after paste commands. (If this option is enabled already, +V acts like +VV.)

+VV Like +V, and enable emacs-style paste buffer functions for "delete word" and "delete to end of line" commands (^T, ^K).

-W  Select WordStar mode. This configures WordStar command key layout and enables many functions of the ^K, ^O, and ^Q menus.

-B  Enforce the Del control character to delete left, Backspace to move left. Should normally not be used, see "Automatic backspace mode adaptation" below.

+k  →NEW→ Enforce usage of terminal "keypad mode" which switches the numeric keypad to send "application keypad" escape sequences. This is normally not needed. On certain terminals, mined will automatically use this mode (e.g. Linux console), and in terminal emulators it is usually not needed unless you are running a misconfigured X windows system in which case you can enable distinguished keypad functions by using the NumLock function of the keyboard and switching on this option.

-k  Assign the more usual functions "goto line beginning", "goto line end" and "delete character" to the Home, End and Del keys of the right keypad ("numeric keypad"). The (assumedly more useful) mined default is to assign the frequently used paste buffer functions (mark, copy, cut) to these keys.
    In turn, the assigned functions of the Home and End keys of the small keypad ("editing keypad") are exchanged to provide the other function than on the right keypad, respectively - provided the terminal and its configuration support this distinction.
    Also Alt-Home/End is assigned the respective other functions so the most useful keypad functions should always be quite easily available.
    Regardless of this switching, mined tries to map fixed functions to modified Home and End keys: Ctrl-Home/End for line begin/end movement (both keypads), Shift-Home/End for the paste buffer copy functions (small keypad) - provided the terminal, its mode and configuration support distinction of modified keypad keys.
    See also the section on Keypad layout for a motivating overview of the mined keypad assignment features and options.
    About terminal support and configuration, see Keypad configuration for further hints.

-*  Disable mouse support.

-M  Suppress display of menu header line (including flags). Pull-down and pop-up menus can still be opened with keyboard commands. →NEW→ Mouse control remains enabled.

-oN Select scrollbar display mode. N=0 disables the scrollbar (may speed up editing on slow remote lines), N=1 enables cell-grained scrollbar display, N=2 (default) enables finer-grained scrollbar display on a UTF-8 terminal.

-oo Selects old (until 2000.14) left/right click behaviour on scrollbar.

-o  Toggles the scrollbar.

-p  Enables distinguished display of line ends and paragraph ends with different symbols.

-X  Disables display of the filename in the window title bar.

-s  Stay with cursor in top line after page down or bottom line after page up instead of center line.

-S  Use scrolling for page up/down.

-dN Apply delay between lines of page output to achieve visually effective display build-up which may help to quickly focus on the new cursor position (the screen output is displayed starting from the cursor position, proceeding to the screen edges).
        If N lies between '0' and '9', the respective number of milliseconds is applied between display of two lines. If N='0', still an output flush is performed. If N='-', no delay at all is applied though still the order of display output is from cursor position to edges.
        Default: '-'; configuration is currently disabled in the Unix version as 'usleep' doesn't seem to be very portable.

+p  Enables support for proportional display fonts. (Not really tested as there doesn't seem to exist a terminal emulator that handles proportional fonts and cursor positioning correctly.)

All options are also looked for in the environment variable MINED.

Editing text with mined
Mined is always in insert mode. Commands are single control characters, double key commands starting with ESCAPE, and a collection of function keys (for various types of keyboards and terminals). As a specialty, note the prefixing 'HOP KEY' which amplifies the effect of certain commands "just as you would expect"; this provides for more command flexibility without having to remember too many keys. It is described in a separate section below.

  Keypad layout
Control key layout for basic movement functions is topographic on the left-hand side of the keyboard (an idea originating from early editors, when keyboards didn't have cursor keypads). (Although using a cursor block is more comfortable, a simple set of control key assignments is useful as a fallback on terminals or remote connections with reduced functionality.)

The right-hand cursor block of typical keyboards is assigned the most important movement and paste buffer functions.

Keypad assignment features:

    •   central placement of HOP key (see below)

    •   integration of frequently used copy/paste functions

                        +------+------+------+
                        | (7) | (8) | (9) |
                        | Mark | ^ | PgUp |
                        +------+------+------+
                        | (4) | (5) | (6) |
                        | <- | HOP | -> |
                        +------+------+------+
                        | (1) | (2) | (3) |
                        | Copy | v | PgDn |
                        +------+------+------+
                        | (0) | (.) |
                        | Paste | Cut |
                        +------+------+------+

    Note that the mined keypad function assignment as shown here deviates from the more usual assignment of Home/End to "move to beginning/end of line" and Del to "delete character". This is deliberately designed to provide more useful functions to easily available keys, while e.g. line movement can also easily be achieved with HOP cursor-left or HOP cursor-right, respectively, and - depending on the terminal configuration - character deletion may still be done with the small keypad Del key.
This keypad function assignment gives you the best benefit of keypad usage and is thus considered much more useful than the commonly expected "standard assignment" although now and then a user is irritated by it. As there is often a conflict between the mined keypad assignment and commonly expected function assignments of some keypad keys, mined tries to conciliate this issue as follows:

    •   Alt-Home/End/Del is mapped to the more common Home/End/Del function assignments (line navigation and character deletion).

    •   Mined assigns different functions to the Home/End/Del keys on the numeric keypad and the similar keys on the small keypad (whenever possible with the terminal) in order to avoid the waste of resources by the usually redundant mapping of these two keypad blocks.

    •   The -k option switches keypad function assignments:
        Home/End/Del of the numeric keypad invoke line navigation and character deletion.
        Alt-Home/End/Del invoke the paste buffer functions.
        Also small keypad Home/End/Del keys are exchanged accordingly.

    •   Using Del without a paste buffer gives an additional hint on alternative usage.

    •   Regardless of -k mode, Ctrl-Home/End/Del is mapped to the line navigation and character deletion functions, while Shift-Home/End/Del is mapped to the paste buffer functions.

    •   Note: Keypad function assignments as described depend on terminal support to distinguish all involved keys and modifiers which is unfortunately not always the case.
        Terminal support for proper distinction of different keypads and modified keys may be enhanced by appropriate terminal configuration, see the manual section on Keypad configuration.

  The HOP function
This function, triggered by any of the HOP keys, amplifies (or modifies) functions as listed below. To achieve the combined function, first press any key that is assigned the HOP function, then any key assigned the second function:

HOP char left
    move cursor to beginning of current line

HOP char right
    move cursor to end of current line

HOP line up
    move cursor to top of screen

HOP line down
    move cursor to bottom of screen

HOP scroll up
    scroll half a screen up

HOP scroll down
    scroll half a screen down

HOP page up
    move to beginning of file

HOP page down
    move to end of file

HOP word left
    move cursor to previous ";" or "."

HOP word right
    move cursor to next ";" or "."

HOP delete tail of line/line end
    delete whole line

HOP delete whole line
    delete tail of line

HOP delete previous character
    delete beginning of line

HOP set mark
    go to mark

HOP search
    search for current identifier

HOP search next
    repeat previous (last but one) search

HOP copy/cut
    copy or cut, but append to buffer

HOP save buffer
    save buffer, but append to file

HOP paste buffer
    paste "inter-window buffer", which is the last saved buffer by any invocation of mined on the same machine by the same user.

HOP edit next file
    edit last file

HOP edit previous file
    edit first file

HOP exit current file
    exit mined

HOP suspend
    suspend without writing file

HOP show status line
    toggle permanent status line

HOP enter HTML tag
    embed copy area in HTML tags

While a pull-down or pop-up menu is open, any HOP key or the Space key or the middle mouse button toggles the HOP amplifier for a function subsequently invoked in the menu; the menu redisplays with function names changed where applicable.

  Character-oriented navigation and editing
From the traditional restriction of Unix tools to the line as a unit of operation, other editors have derived a line-oriented movement and insertion paradigm which is a nuisance for anyone who wants an editor with decently intuitive operation.
    Mined handles the end-of-line character like any ordinary character during movement and editing operations. Also search and replace strings can contain line ends.

  Mouse control and menus
All versions of mined (Unix, DOS/Windows) support mouse operation.
    Mouse control operates on pull-down and pop-up menus, flags, the text area, the bottom line, and the scroll bar, in order to provide the most useful functions and menu-driven command selection at hand.

Summary of mouse functions:

    In text area:

        •   left click moves the text cursor to the mouse position

        •   left click-drag-release selects a text area and copies it to the paste buffer

        •   middle click display the text status line

        •   right click pops up the quick menu

        •   mouse wheel scroll scrolls by N lines (default 3, adjust with option -L) Ctrl-mouse-wheel always scrolls by 1 line. Shift-mouse-wheel scrolls by 1 page. →NEW→ Note: Mouse-wheel on the scrollbar scrolls by half a page.

    On scroll-bar:

        •   left click →NEW→ moves one page towards the mouse position (as seen from the current scrollbar position marker)
            or (with option -oo) moves one page down

        •   middle click moves to text position in file corresponding to relative mouse position on scrollbar

        •   →NEW→ left click-drag moves text position in file with moving relative mouse position on scrollbar

        •   right click →NEW→ moves one page away from the mouse position (as seen from the current scrollbar position marker)
            or (with option -oo) moves one page up

        •   mouse wheel scroll →NEW→ scrolls by half a page

    On bottom line (status line):

        •   left click moves one page down

        •   middle click displays the text status line

        •   right click move one page up

    On pull-down menu header (in left menu area of upper line):

        •   left or right click →NEW→ or mouse wheel scroll opens menu

        •   middle click opens menu with HOP-modified functions

    On flag indication (in right flag area of upper line):

        •   middle click toggles flag

        •   left click (deprecated) toggles flag (should open menu in a future version)

        •   right click →NEW→ or mouse wheel scroll opens flag menu

    On open menu

        •   mouse wheel scroll navigates in menu

        •   left click invokes menu item pointed to with the mouse

        •   left or right drag (holding key down after opening the menu) navigates in menu

        •   left or right release (after mouse dragging) invokes selected menu item

        •   middle click toggles HOP modifier

        •   Ctrl-mouse-wheel →NEW→ switches to next or previous menu

    Configuration hint: To enable mouse operation in a Windows console window, deactivate "QuickEdit mode" in the properties menu.

  Menus
Mined provides three kinds of menus, all can be opened with either mouse clicks or commands. The menus offer the most important editing functions (apart from simple movement). Some menus have their items grouped into sections, some of which have subtitles.
The HOP flag can be toggled while a menu is open with any of the HOP key, ^G, Space, or the middle mouse button. When a pull-down menu is opened with the middle mouse button, the HOP variation is initially triggered, offering the HOP variations of the menu items.
The three menu groups are used as follows:

    •   A pull-down menu is opened by clicking the mouse on the menu header (in the left part of the top screen line) →NEW→ or scrolling the mouse wheel on this header.
        Shortcut: Each pull-down menu can also be opened with ESC or Alt and the small initial letter of the menu header (Alt-f or ESC f for the file menu etc.).

    •   A flag menu is opened by clicking the right mouse button on a flag indication in the flags area (right part of the top screen line) →NEW→ or scrolling the mouse wheel on it. The flag menus have optional markers in front of each item showing which items are currently active.
        Shortcut: The Info menu, Input Method (Keyboard Mapping) menu, Smart Quotes menu, Encoding menu can also be opened with Alt-F10, ESC I or Alt-I, ESC K or Alt-K, ESC Q or Alt-Q, ESC E or Alt-E, respectively.

    •   The pop-up menu is placed above the text area and can be opened with a right-click or Alt-Space (ESC Space).

  Menu navigation
When a menu is open, the cursor-left or cursor-right keys cycle through the pull-down and flag menus. Alt-cursor-left and Alt-cursor-right navigate quickly between the two sets of menus (pull-down or flag menus).
When a sub-menu is open, cursor-left goes back to the parent menu, cursor-right opens its next menu to the right.

There are three methods to navigate within a menu:

    •   With the keyboard: open menu as described above, navigate with cursor keys or by typing the first letter of the desired menu item (which cycles through all items starting with that letter, or →NEW→ containing a word starting with that letter); activate menu item with Enter key.

    •   With mouse clicks: open menu with click (and release) mouse button, switch to other menu with another click, click on item to activate it. The mouse wheel may be used to navigate menu items.

    •   With mouse dragging: open menu with mouse button (left or right), browse menus and items with button held down, activate selected item with releasing mouse button.
Methods may be mixed, e.g. open a menu with either mouse click or keyboard, navigate with mouse wheel, then select with Enter.

When selecting a menu item, in most cases the associated function is carried out and the menu closed afterwards. →NEW→ In some cases, an option is toggled and the menu stays open (esp. in Info menu: Han info pronunciation selection, character information "with" attributes selection).

    Scrollable menus: In a low-height terminal (e.g. 24 lines), longer menus (especially the Encoding menu and the Input Method menu) may not fit on the terminal. All menus are scrollable with cursor keys, including Page Down/Up, Home, End keys.
When the window size is changed, open menus are closed in order to prevent resizing and repositioning problems; this is planned to be enhanced in a future version.

  Hints

    Note: Your mouse driver or Windows system may be configured to generate multiple (e.g. 3) mouse wheel events on one mouse wheel movement (e.g. with Windows). An option -L1 could compensate for that scaling (as mined applies a mouse wheel factor by itself which is 3 by default).

    Layout configuration: See Menu display below for configuration of menu appearance.

    Configuration hint: On Unix, in order to make Alt work as a modifier, set the xterm resource metaSendsEscape to true and the rxvt resource meta8 to false as suggested in the example file Xdefaults.mined in the Mined runtime support library. (With older versions of xterm, setting eightBitInput to false may be required instead; this xterm option doesn't actually disable 8 bit input as its name might suggest.) With xterm, this setting can also be enforced dynamically with the +D option.

  Inter-window paste buffer
Mined can perform copy/paste operations within different editing sessions (parallel or subsequent invocations of mined): The command HOP Ins (e.g. ^G ^P) will insert the most recent paste buffer copied or cut in any of the user's mined sessions. This can also work remotely in a network; to configure this features, see Common paste buffer configuration.

  Multiple paste buffers
Mined provides emacs-style multiple paste buffers that are organised as a buffer ring. Every buffer cut or copy operation (that places the text between the marked and the current position to the buffer) creates a new buffer and stacks it to the list of buffers. If the feature "deleted word/line appends to buffer" is enabled (+VV) the commands delete-end-of-line (^K), delete-word (^T) and delete-end-of-sentence (currently emacs mode only) append to the top buffer (disabled with the option -VV).
To paste a non-top-most buffer, paste the most recent buffer first as usual, then use the buffer-ring command (Alt-Ins or Ctrl-F4, or M-y in emacs mode) to exchange the pasted text with the previous buffer. This can be repeated, going down the stack of buffers, and at its bottom, starting over from the top again.

  Text position markers
A default marker for quick use and additional 10 numbered text markers are available.
Marker 0 has a special function: 1. it is set when opening a file at the memorized position, 2. whenever a new current marker is set, the previous one is pushed to marker 0.

  Text position marker stack
In addition to the explicit text markers, mined implicitly maintains a marker stack to support navigation and orientation when browsing files. Whenever a command moves the position by a far distance (Go to marker, Go to line, Go to file beginning/end, Go to next/previous file, Search functions including Search identifier definition across files, Replace with confirm), the current position is first pushed to this stack. Later, in order to return to the previous position, use the command ESC Enter (Alt-Enter) to move along the positions in the marker stack. The command HOP ESC Enter (HOP Alt-Enter) moves again forward along the stack.

  Paragraph justification / word wrap
Manual paragraph line/word wrap is invoked with the justify command (ESC j or ESC J); it justifies the current paragraph (wraps its lines/words) according to the effective margins and paragraph termination mode.
Clever justification: With ESC j, mined automatically determines left margins depending on the current paragraph and line contents. Heuristic detection of numbered items will trigger automatic indentation.
Normal justification: With ESC J, mined justifies strictly according to the margin values currently configured.
See commands listing below "ESC j" for margin setting commands.

Paragraph termination modes: Two different definitions of paragraph end are available.

    •   The primary mode is to add a space at the end of each line when the paragraph continues and to end the line without space where the paragraph ends. This seems an intuitive way and as a big advantage over other approaches, it is transparent with respect to visual formatting, i.e. no text property is required that would affect visual layout of the text.
        Note: Additional visual support of paragraph end detection is available with the mined option -p that distinguishes paragraph/line end display.

    •   The other word-wrap mode is to add an empty (blank-only) line after each paragraph. Obviously this imposes more additional requirements on text formatting discipline and reduces freedom of text layout.
The mode in effect is indicated in the mode indication display; see description there.

  Auto indentation
By default, mined acts in auto-indent mode: When you enter a newline, the following line will be filled with the same prefix of space characters (Space or Tab) as the current one. This option can be toggled from the Options menu. A new line without auto indentation can be entered with the ^O command.

    Auto indentation is automatically suppressed if text is entered very fast (by heuristic detection of input speed) in order to allow unmodified copy and paste using terminal mouse functions.

  Structure input commands
A pair of parentheses with matched indentation can be entered by prefixing a parenthesis character with HOP. For example, HOP "{" would enter a pair of "{" "}", both auto-indented on their respective new line. Other pairs are "(" ")", "[" "]", "<" ">".
    HOP "/" enters an indented Javadoc comment frame.

  Back-Tab (Undent function / reverse indent)
A Backarrow key from a position that is only preceded by white space on the line and on the line above will revert the input position to the previous matching indentation level. To avoid auto-undentation ("Delete single"), use Ctrl-Backarrow or F5 Backarrow to delete only one character left. (Ctrl-Backarrow only works if configured in your X configuration, see the example configuration file Xdefaults.mined in the Mined runtime support library.)

  Tab expansion
With one of the options -+4 or -+8, a Tab key input will be expanded to an appropriate number of Space characters instead of inserting a Tab character. You can still insert a literal Tab character with Ctrl-V Tab.

  Search and replace multiple lines
Mined has overcome the typical Unix tool limitation of line orientation in search operations. Search and replacement patterns can contain embedded newlines. Enter a newline (linefeed character) in the search string with ^V^J or \n (or \r to match CRLF newlines). (In some cases there are still display problems; then update the screen with the ESC "." command.)

  Header line underlining
The command HOP "-" (e.g. Ctrl-G -) underlines the header line before the cursor position with as many "-" characters as needed; it applies to the current line unless the cursor is at a line beginning in which case it applies to the previous line.

  Automatic backspace mode adaptation
There is much confusion about what character codes are delivered by the Backarrow and Del keyboard keys in different operating environments and configurations. For proper operation, the "stty erase CHAR" configuration should generally be set correctly to reflect the actual code emitted by the terminal. Mined detects this setting and adjusts its handling accordingly, so that the "Backarrow" key should normally work as expected (delete a character left).

Overview: input support features

  Character input
Mined provides several methods to support input of special characters that may not be easily available on the keyboard.

    •   Accented and mnemonic input support defines Accent prefix keys to compose accent combinations with subsequently entered characters.

    •   It also provides Character input mnemonics for easily memorisable input of a wide range of characters, including most composed Unicode characters.

    •   Input support commands include a quick shortcut for two-character mnemonics.

    •   Input support commands also provide for character input by hexadecimal / octal / decimal character code or Unicode value, including support for subsequent entry of multiple numeric characters according to ISO 14755.

    •   Keyboard mapping switching the keyboard to support another script. This mechanism also provides CJK input methods.

  Structured input

    •   HTML tag input (starting/closing or embedding marked text).

    •   Auto indentation and Back-Tab.

    •   Structure input commands: Input of indented matching parentheses and Javadoc frames.

    •   Paragraph justification (line/word wrap).

    •   Header line underlining

  Special features

    •   Smart quotes automatic transformation of entered straight quote marks into typographic quotation marks (style can be selected in flags area), as well as smart dashes and other smart text replacements.

    •   Right-to-left script input support.

Handling files with mined

  Tags file support
The ESC t command moves to the definition of an identifier (on which the cursor should be placed) using the tags file (generated by the ctags command). HOP ESC t prompts for an identifier. (Also available from search or popup menu.) If a new file is opened for this purpose, the current file is saved automatically.
Like with a number of positioning commands, ESC t places the current position on the position marker stack before going to the location of the identifier definition. The command ESC Enter (Alt-Enter) moves back to that position, also saving the current file if needed first.

  Data security
Mined has a robust and defensive concept of handling edited text and file contents in case of any kind of program or system errors.

  Edited text
Every care has been taken to prevent loss of the edited text in case of save errors or accidental quit commands etc; mined always prompts before discarding any modified text (not all popular editors are so careful about this, e.g. emacs when editing text without associated filename).
In the rare case of an unrecoverable error (out of memory or terminal I/O error) or if mined is interrupted by an unexpected signal, mined needs to terminate but it tries to save the edited text (if modified) into a panic file in one of the directories $MINEDTMP, $TMPDIR, $TMP, $TEMP, /usr/tmp, or /tmp (whichever variable is defined first and directory is writable in this order). If possible, mined also tries to continue normally after panic handling unless multiple external signals are nested. Only if the temporary area happens to be full and mined cannot continue either you would be out of luck.
If mined is sent an explicit SIGTERM signal it tries to terminate normally, writing modified text to the file being edited (this would involve normal interactive handling if that file is read-only or the file name was changed).

  Files
Also, if any command is issued to write to a file not previously read in (after change of file name or working directory, or with a Copy to file command), mined prompts for confirmation.

  File access permissions
When creating a new file, its access permissions are set according to the default behaviour set in the user environment (umask setting in Unix). →NEW→ However, when cloning a file (with Save As / Set Name / ESC n / ESC d), file access permissions of the originally opened file are preserved and cloned.
The +x command line option adds executable permission to newly created files →NEW→ but only to those users that are also given read permission by the rules above.

  Pipe output
In the "write to standard output" mode (i.e. when invoked within a pipe), only one "file save" operation can be performed writing to standard output. If more than one such operations are issued (e.g. using the ESC w / F2 , F3, or suspend command) only the first one will write the text buffer to standard output; any subsequent one is treated as usual (with empty file name).

  Line end modes and binary-transparent editing
Mined is binary transparent. It can handle all types of line ends (Unix, DOS, optionally Mac, and Unicode separators) simultaneously in the same editing session. They are indicated by different visible line end indications. Files without trailing line end can be edited and created (using the delete character right function on the last line end). NUL characters are handled as virtual line ends. Lines too long for internal handling are split transparently (with a "none" virtual line end).
    Character codes that are illegal in the currently selected text encoding are maintained transparently and are clearly indicated (e.g. illegal UTF-8 sequences in Unicode text).
    Files with mixed encoding (e.g. UTF-8 / 8 bit sections) can be edited comfortably.
    Input: To enter a NUL character, use ^V # 0 or ^V < NUL or Ctrl-Space > (if the keyboard supports the latter).

  Memory of file position and editing style parameters
If the current directory contains a file named @mined.mar , file position memory is enabled.
    The current cursor position is stored with every file save command (even if no write is performed because the text has not been edited). When editing that file again, mined will automatically move to that position (and set text marker 0 to it). (The association of the position is not with the file itself but with its relative name from the current directory.)
    This mechanism is enabled in each directory by using the command "Save Position" from the File menu, or by using Ctrl-F2 to save a file or by prefixing any file writing command with HOP. This enforces creation of the marker file.
    →NEW→ Note: With mined 2000.14, the saved position is changed from the screen column to the actual character position. This makes a difference in two cases: when the current position is within a combined character, and when the same file is opened in terminal windows with different width properties. Previously stored visual positions are handled compatibly, but when a file is stored with new position memory mode and reopened with an older version of mined (e.g. on a different machine), the column position would just be set to 0.
    →NEW→ Note: With mined 2000.14, mined applies "housekeeping" to the position entry for the current file, i.e. it removes old entries for the same file name. Note that this housekeeping is, however, only done for the file being edited, not for other files listed in the marker file. Also note that old style file position memory is used on PC versions (e.g. djgpp) as updating the marker file does not appear to work there.

    In addition to the current position, mined also stores the paragraph justification margins (only if automatic paragraph justification is active) and the selected Smart Quotes style.

  Page length
The command ESC P sets the number of lines that mined assumes to be on a page. So the status line can contain the page number to make finding the current position in a print-out easy. Also the Goto Line/% command (^G etc.) accepts a final
 'p' or 'P' in which cases it positions to the top of the given page. This information will be associated and stored with the file name if file position storing is active (i.e. if the file @mined.mar exists in the current directory).

  File names
When entering file or directory names, the leading ~ notation to refer to one's home directory is accepted.

  Restricted mode (tool mode)
Restricted mode is activated with
        <code>mined -- [ filenames ... ]
In restricted mode, only the file opened when mined was started can be edited, no commands changing file name reference, involving other files (copy/paste), or escaping to a shell command will be allowed. (When mined is invoked without filename argument, a file name will be prompted for despite restricted mode, however.)

  Version control integration
From the File menu, checkout and checkin commands are available that invoke "co" or "ci" scripts, respectively (which must reside in the user's command search path). This offers a gateway to ClearCase or other version control systems; mined applies automatic save or screen update as appropriate.

  Printing
From the File menu, a print command is available that prints the text currently being edited. If the script uprint is installed and configured properly, printing works in any selected character encoding. See Printing configuration for further details.
→NEW→ Under Windows, if neither of the formatting tools paps or uniprint happens to be installed, uprint uses notepad /p for printing. The djgpp-compiled version uses notepad directly.
Note: The font size interactively configured in notepad also affects the print size; a font size of not more than 10pt gives you at least 80 characters per line; if 72 characters per line are enough, you can use 11pt font size.

Working with mined

  Mode indication flags
The right side of the top menu bar displays a number of one-letter or two-letter indications for certain modes; the associated flag menus can be opened from here with a mouse right-click, or the modes can be toggled quickly with a middle-click. (Keyboard shortcuts for handling flags and menus are also available.)

    •   Information display mode

        •
                "?": this flag menu offers options for permanent File info, Char info, or Han character information display. For Char info and Han info, further options can be selected to configure the information shown.
            (Note that in extreme situations, permanent File info display might cause swappping (when editing a file that does not fit completely in memory, e.g. large file on old system). In that case, disable the feature.)

    •   (In non-Latin-1 text and terminal mode only) Input Method (Keyboard Mapping)

        •
                "--": no keyboard mapping is active.

        •
                "...": a two-letter input method tag indicates that an according keyboard mapping is active, mapping keyboard input to characters of the selected Unicode script range, or using a more complex CJK input method involving "pick list" selection menus. See Keyboard Mapping and Input Methods below.

        •
                Right mouse button on this indication opens a menu for selection of the desired keyboard mapping.

        •
                Left mouse button on this indication toggles between the current and the previous selected keyboard mapping.

    Note: In the open Input method menu,
        the last column indicates the source of the input method with a short tag as follows:

        •
                "U": generated from Unicode data file UnicodeData.txt

        •
                "H": generated from Unihan database Unihan.txt

        •
                "C": transformed from cxterm input table

        •
                "M": transformed from input method of the m17n project

        •
                "Y": transformed from yudit keyboard mapping file

        •
                "V": transformed from vim keymap file

        •
                "X": transformed from X keyboard mapping file

    •   Smart Quotes

        •
                Two quote marks are displayed that act as automatic "smart quotes": When you type a «"» or «'» character (straight double or single quote), it is replaced by an opening or closing typographic quote mark (double or single, respectively), depending on the text context.

        •
                Right mouse button on these indications opens a menu for selection of the desired quotation marks style.

        •
                Left mouse button on this indication toggles between the current and the previous style selected with the menu.

    •   Character encoding (used for text interpretation)

        •
                A two-letter character encoding tag indicates the text encoding currently assumed for display. Changing the encoding changes the interpretation of the text which is otherwise handled transparently; it does not recode the text.

        •
                Right mouse button on these indications opens a menu for selection of the desired quotation marks style.

        •
                "«": empty line terminates paragraph

  Scrollbar
By default, mined displays a scrollbar at the right side. It may be used for position indication within the text and for relative or absolute positioning with the three mouse buttons.
In a UTF-8 terminal, mined uses Unicode character cell vertical eighths characters U+2581..U+2587 for a fine-grained scrollbar display. If your Unicode font doesn't include those block characters, you may switch to the cell-grained scrollbar with the -o1 option.

  Text position marker stack
On commands that jump away from the current position (HOP Mark, File Begin/End, Search, Search identifier definition, Search current character, Goto Line/%, Goto Next/Previous File), the current position is remembered in a position stack. The command ESC Enter goes backward, HOP ESC Enter forward in this "stack", even if this means switching the file being edited.

  Structured editing support

  HTML support: syntax highlighting and tag entry/matching
HTML tag entry: With the ESC H commands, opening and closing HTML tags can be entered or (with HOP) a marked area can be enclosed into HTML tags.
Syntax highlighting: HTML tags are displayed in light blue colour to set them back from the actual text contents. Other highlighting modes apply to HTML comments and JSP code. This option is activated if the file name suffix is one of .html, .htm, .xhtml, .shtml, .sgml, .xml, .xul, .jsp, .asp, .wsdl, .dtd, .xsl, .xslt; it can be toggled from the Options menu.
HTML tag matching: With the ESC ( or ESC ) command, mined searches for the opening / closing HTML tag corresponding to the current one.
Note: While you edit within a line and change its HTML ending status (by entering or deleting '<' or '>'), the display status of subsequent lines is not changed. (You may refresh the display with ESC ".")
Configuration hint: The colour used for displaying HTML tags can be configured with the environment variable MINEDHTML using an ANSI sequence, e.g. MINEDHTML=34 (the default).

  Search structure match
With the ESC ( or ESC ) commands, mined searches for a matching end of various structures, like opening/closing HTML/XML tags (see above), matching parentheses or brackets, matching comments (/* */), matching conditional macros (#if...), mail messages (in a mailbox file), MIME attachments. See the ESC ( command in the command reference for details.

  Structure input
A structure template with opening and closing ends can be inserted with the structured input feature. HOP followed by one of { , ( , [ , < enters a corresponding bracket pair, HOP / enters a Javadoc comment frame. HOP - enters an underlining line matching the previous line.

Visual structure input is supported by Auto indentation

  Password hiding
With the option -P, mined hides one word (separated by white space) behind the string "assword" in a line (to accommodate for "password" or "Password") and displays reverse "*" instead. Password hiding can be disabled with +P.
By default (without any P option), password hiding is activated when editing a file whose file name starts with "." (Unix "hidden" file convention).

  Long line splitting
Mined has an internal line length limit (> ca. 1024 characters). When opening a file, longer lines are split. This is handled transparently as virtual "none" line ends are used and indicated. When saving the file, lines will be joined again.

  Visible indication of line contents and display
Various options are available to indicate line control characters (Tab and line-feed) as well as shifted line display (of lines longer than the screen width). (So you can see how many dummy blank spaces there are before the line ends or how many superfluous blank spaces precede a Tab character.)
    Environment variables can be used to modify these indications. See Display of contents indications and scrollbar for details.
    Default indications and according configuration variables:

«   LF (Unix-type line end)
    customise indication with MINEDRET or MINEDUTFRET (may contain up to 3 characters to configure different appearance behind the line end)

«   CRLF (MSDOS-type two-character line end)
    on black and white terminals, µ is used instead
    customise indication with MINEDDOSRET or MINEDUTFDOSRET

«   CR (Mac-type line end)
    on black and white terminals, @ is used instead
    customise indication with MINEDMACRET or MINEDUTFMACRET
    transparently handled and displayed with +R command line option

º   NUL character (pseudo line end)

¬   "none" line end (virtual line end as used to split input lines too long for internal handling; will be joined into a single line when saving the file)

·   no-break space (Unicode character U+00A0)

«   Unicode line separator

¶   Unicode paragraph separator
    customise indication with MINEDPARA or MINEDUTFPARA

¶   end of paragraph (if enabled by -p)
    customise indication with MINEDPARA or MINEDUTFPARA

»   line extending the end of the screen line
    (move cursor right to shift line display)
    customise indication with MINEDSHIFT or MINEDUTFSHIFT

«   line shifted out left of the screen line
    (move cursor left to shift line display back)
    customise indication with MINEDSHIFT or MINEDUTFSHIFT

·   position spanned by Tab character
    customise indication with MINEDTAB or MINEDUTFTAB (may contain up to 3 characters to configure different appearance within the Tab span)

Configuration: Display colour of the indications which are by default red can be changed with the environment variable MINEDDIM, display colour for Unicode line end indications with MINEDUNIMARK. Their values should be the numeric part of an ANSI terminal control sequence, e.g. 31 for red, "33;44" for yellow text on blue background. →NEW→ MINEDDIM can also be set to an empty value to have mined apply dim colour to the indications; the colour value is computed from the current foreground and background colours (works in xterm).
For more details and recommended settings see the example script file profile.mined in the Mined runtime support library. Default values are compiled in and can be overridden by setting the variables to empty values.

Note: With the -F option, mined limits usage of special characters for line indication and suppresses the interpretation of the MINEDUTF* environment variables.

  Function key help bars
For quick reference of functions attached to function keys, modified function keys, and other modified keys (as used for accent prefix functions), a number of help bars can be displayed in the bottom line.
F1 followed by another F1, optionally modified by a combination of Control/Shift/Alt, displays a help line with function attachments to the respectively modified function keys; F1 followed by Ctrl-1/Alt-1/Alt-Ctrl-1 or Control with a punctuation key (e.g. Ctrl-,) displays a help line for the respective accent prefix functions attached. See the F1 help bars command reference for details.

  Menu display
Menu borders are displayed using Unicode Box Drawing characters in a UTF-8 terminal, using VT100-mode block graphics characters if they are detected to be available, or using ASCII graphics otherwise.
Configuration hint: The menu style option -Q is available to configure your style preference; see also Terminal interworking problems for configuration hints to deal terminal-related graphics display trouble. Alternatively, the option -f reduces font assumptions and adjusts usage of special characters accordingly.
In addition to round or rectangular corners, also fancy item selection display style can be selected (-Q).
With a non-UTF-8 terminal, if your system's termcap/terminfo database does not indicate the VT100 block graphics capability for the terminal you use but you know (or want to try if) your terminal has that capability, use of graphical borders can be enforced with the -Qv command line option.
Configuration hint: The colour of menu borders can be →NEW→ changed with the environment variable MINEDBORDER. The marker of selected items in flag menus can be changed with the environment variable MINEDMENUMARKER.

Language support
Most of the information in this chapter is redundant. It collects language-specific features described in the other chapters in a more technical context, here assorted by languages / scripts for more convenient quick reference.
An overview of typographic quotation marks support is given at the end of this chapter.

  Western languages

  Character sets
In addition to Unicode, mined supports ISO Latin-1, Latin-9, Mac-Roman, Windows (CP1252) and DOS (CP437, CP850) Western character sets. To view and edit a file in one of these encodings, select it from the Encoding menu (section "8 Bit" or sub-menu "more Latin"), or use the respective command line parameter. See Character encoding flags for details.
Terminal: If your terminal runs any of these encodings, mined can detect this by proper setting of environment variables (LC_*, LANG or TERM). See Terminal environment for details.

  Character input support
For input of accented characters and ligatures, mined provides an extensive set of accent prefix functions, as well as mnemonic input. See Character input support for more details.

  Language-specific mnemonic conversion support
The generic mnemonic transformation command ESC _ (which transforms a mnemonic transcription in the text into its accented or ligature character) has a few national variants, using keys available on the respective keyboards as commands:

    •   German: ESC ö etc. transforms ae to ä, oe to ö

    •   French: ESC é etc. transforms ae to æ, oe to oe ligature

    •   Scandinavian: ESC å etc. transforms ae to æ, oe to ø
(See mnemonic character substitution commands in the Command reference for details.)

  Other Latin-based languages

  Character sets
In addition to Unicode, mined supports ISO character sets for Central European, South European, Turkish, Baltic, Nordic, Celtic, Romanian. To view and edit a file in one of these encodings, select it from the Encoding menu (sub-menu "more Latin"), or use the respective command line parameter. See Character encoding flags for details.
Terminal: If your terminal runs any of these encodings, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Language-specific case conversion

Lithuanian: Case conversion of accented i with retained i dot is handled properly if a Lithuanian locale setting is detected (LC_ALL/LC_CTYPE/LANG begins with "lt").

Turkish and Azeri: Case conversion of i/dotless i is handled properly if a Turkish locale setting is detected (LC_ALL/LC_CTYPE/LANG begins with "tr" or "az").

  Esperanto

  Character sets
In addition to Unicode, mined supports the Latin-3 character set, plus the DOS codepage CP853 (especially as terminal encoding). To view and edit a file in Latin-3 encoding, select it from the Encoding menu (submenu "more Latin"), or use the command line parameter -E3. To tell mined it runs a CP853 DOS setting, use a LC_CTYPE variable setting (.CP853) or the option +E=CP853. See Character encoding flags for details.
Terminal: If your terminal runs this encoding, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Input method
→NEW→ Mined supports a built-in input method for Esperanto, using the "x-system", plus "Sm" for the Spesmilo sign. Select it from the Input method menu.

  Accented character input support

  Accented character input support
See above for Cyrillic accented input support.

  Script highlighting
Cyrillic is by default displayed with colour highlighting.

  Georgian

  Character sets
In addition to Unicode, mined supports Georgian-PS. To view and edit a file in this encoding, select it from the Encoding menu (sub-menu "more Cyrillic", tell me if that's not suitable), or use the respective command line parameter -E:GP. See Character encoding flags for details.
Terminal: If your terminal runs this encoding, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Greek

  Character sets
In addition to Unicode, mined supports ISO Greek. To view and edit a file in this encoding, select it from the Encoding menu (sub-menu "Greek/Oriental"), or use the respective command line parameter -E:I7. See Character encoding flags for details.
Terminal: If your terminal runs this encoding, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Input method
Mined supports a built-in input method for Greek. Select it from the Input method menu.

  Accented character input support
In combination with a Greek input method or keyboard, →NEW→ mined provides accent prefix support for both monotonic Greek and polytonic Greek.
Monotonic Greek uses only one accent, the tonos which looks like acute and can be entered with the F6 or Ctrl-' prefix function.
Polytonic Greek uses - among many others - the oxia accent which is nowadays considered identical and looks like the monotonic tonos. However, for historic reasons, there are two sets of Greek accented letters with this accent in Unicode, one with tonos and one with oxia. While this may be considered a design flaw of Unicode, in fact both kinds of characters exist and mined provides support for both accents. The choice of usage is up to the user. Note, e.g. that

F6 < alpha >
    enters the Greek letter alpha with tonos

Ctrl-F6 < alpha >
    enters the Greek letter alpha with oxia

Likewise, with mnemonic input

^V ' < alpha > (using the apostrophe key)
    enters the Greek letter alpha with tonos

^V ´ < alpha > (using the acute accent key)

In these examples, < alpha > indicates the Greek letter alpha, which may e.g. be entered by selecting the Greek input method and typing the a key.

Accent prefix functions for Latin letters are reused for Greek accents, see the following table:

F5

Ctrl-:

Ctrl-"
    dialytika

Shift-F5

Ctrl-~
    perispomeni

Ctrl-F5

Ctrl-,
    iota (ypogegrammeni)

Ctrl-Shift-F5

Ctrl-;
    prosgegrammeni

Alt-Shift-F5

Ctrl-(
    vrachy

F6

Ctrl-'
    (Ctrl-apostrophe) tonos

Ctrl-F6

Ctrl-´
    (Ctrl-acute)

Ctrl-^
    oxia

Shift-F6

Ctrl-`
    (Ctrl-grave) varia

Alt-F6

Ctrl-<
    psili

Alt-Shift-F6

Ctrl-.
    dasia

Ctrl-Shift-F6
    macron

Alt-6
    psili and oxia

Ctrl-Alt-6
    dasia and oxia

    psili and varia

Ctrl-Alt-7
    dasia and varia

Alt-8
    psili and perispomeni

Ctrl-Alt-8
    dasia and perispomeni

For polytonic Greek, 2 or 3 accents can be combined by applying the respective accent prefix functions in sequence. For convenience, the most frequent combinations of 2 accents are also available as dedicated accent prefix keys as listed above. Also, modified Ctrl-/Alt-/Alt-Ctrl- digit keys are used for polytonic Greek accent prefix functions. See Character input support for more details.

  Script highlighting
To distinguish some Greek letters from Latin look-alikes, Greek is by default displayed with colour highlighting.

  Language-specific case conversion
Case conversion of final sigma is handled properly.

  Amharic

  Input method
Mined supports two built-in input methods for Amharic, one is called "Ethiopic" (source: yudit), the other is called "Amharic" and was generated from Unicode character names (preferable according to user feedback). Select your preferred input method from the Input method menu.

  Arabic

  Character sets
In addition to Unicode, mined supports ISO Arabic and MacArabic. To view and edit a file in one of these encodings, select it from the Encoding menu (sub-menu "Greek/Oriental"), or use the respective command line parameter -E:I6 or -EA. See Character encoding flags for details.

As a special case of smart dash input replacement (enabled together with smart quotes), mined inserts Hebrew Maqaf as a dash in the context of Hebrew letters.

  Chinese

  Character sets
In addition to Unicode, mined supports Big5 (with HKSCS extension), GB18030 (including EUC-CN and GBK), and CNS (EUC-TW) multi-byte character sets. To view and edit a file in one of these encodings, select it from the Encoding menu (section "Chinese"), or use the respective command line parameter -EB or -EG or -EC. See Character encoding flags for details.
Auto-detection: Big5 and GB18030 text encoding are also auto-detected when opening a file (with a certain success rate). Set the environment variable MINEDDETECT="BG" to constrain auto-detection to Big5 and GB18030 encodings. See Mined configuration for details.
Terminal: Mined supports native CJK terminals; make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal encodings support for details on detection and handling of CJK terminal features.

  Input method
Mined provides the following built-in input methods for Chinese: Pinyin, Cangjie, WuBi, 4Corner, Boshiamy, and special support for a Radical/Stroke lookup input method. Select the input method of your preference from the Input method menu.

  Han character information display
Mined provides special support for display of Han character information according to the Unihan database. It comprises semantic information and Mandarin, Cantonese, Hanyu Pinlu, →NEW→ XHC Hanyu pinyin, and Tang dynasty pronunciation.

  Accented character input support
For Latin-based Pinyin transcription of Chinese, the usual accent prefix functionality is available.

  Japanese

  Character sets
In addition to Unicode, mined supports JIS character set in EUC-JP or Shift-JIS multi-byte encoding. To view and edit a file in one of these encodings, select it from the Encoding menu (section "Japanese"), or use the respective command line parameter -EJ or -ES. See Character encoding flags for details.
Auto-detection: EUC-JP and Shift-JIS text encoding are also auto-detected when opening a file (with a certain success rate). Set the environment variable MINEDDETECT="JS" to constrain auto-detection to EUC-JP and Shift-JIS encodings. See Mined configuration for details.
Terminal: Mined supports native CJK terminals; make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal encodings support for details on detection and handling of CJK terminal features.

  Input method
Mined provides the following built-in input methods for Japanese: Hiragana, Katakana, TUT roma, and special support for a Radical/Stroke lookup input method. Select the input method of your preference from the Input method menu.
Mined does not implement, however, advanced Japanese input methods that provide semantics-based Hanja input; for these, you will have to set up or use an external input method with your operating environment, which is then handled by the terminal which delivers ready-composed characters transparently to the application.

  Han character information display
Mined provides special support for display of Han character information according to the Unihan database. It comprises semantic information and Japanese and Sino-Japanese pronunciation.

  Accented character input support
For Latin-based Romaji transcription of Japanese, the usual accent prefix functionality is available.

  Korean

  Character sets
In addition to Unicode, mined supports UHC (including EUC-KR) and Johab multi-byte character sets. To view and edit a file in one of these encodings, select it from the Encoding menu (section "Korean"), or use the respective command line parameter -EK or -EH. See Character encoding flags for details.
Auto-detection: UHC text encoding is also auto-detected when opening a file (with a certain success rate). Set the environment variable MINEDDETECT="K" to constrain auto-detection to UHC encoding. See Mined configuration for details.
Terminal: Mined supports native CJK terminals; make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal encodings support for details on detection and handling of CJK terminal features.

  Input method
Mined provides the following built-in input methods for Korean: Hangul, Hanja, and special support for a Radical/Stroke lookup input method. Select the input method of your preference from the Input method menu.

  Han character information display
Mined provides special support for display of Han character information according to the Unihan database. It comprises semantic information and Hangul and Korean pronunciation.

  Vietnamese

  Character sets
In addition to Unicode, mined supports VISCII and TCVN character sets. To view and edit a file in one of these encodings, select it from the Encoding menu (section "Vietnamese"), or use the respective command line parameter -EV or -EN. See Character encoding flags for details.
Auto-detection: VISCII text encoding is also auto-detected when opening a file (with a certain success rate). Set the environment variable MINEDDETECT="V" to constrain auto-detection to VISCII encoding. See Mined configuration for details.
Terminal: If your terminal runs this encoding, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Input method
Mined provides the following built-in input methods for Vietnamese: VNI and VIQR. Select the input method of your preference from the Input method menu.
It may be more convenient, however, to use the extensive accented character input support provided by mined together with a normal Latin-based keyboard (so without a keyboard-mapping input method), see Character input support for Vietnamese below.

  Character input support
Mined provides input support for multiple accented characters as used in Vietnamese, as well as convenient accent prefix functions for combinations of two Vietnamese accents. Modified Ctrl-/Alt-/Alt-Ctrl- digit keys are used for Vietnamese accent prefix functions. Alternatively, mnemonic character input can be used. See Accented and mnemonic input support for details, and see below for some introducing comments.

An accent prefix can either be applied to the plain Latin base letter, or to a precomposed Vietnamese letter which already has one of the accents. These are:

    U+00C2  LATIN CAPITAL LETTER A WITH CIRCUMFLEX

    U+00E2  LATIN SMALL LETTER A WITH CIRCUMFLEX

    U+00CA  LATIN CAPITAL LETTER E WITH CIRCUMFLEX

    U+00EA  LATIN SMALL LETTER E WITH CIRCUMFLEX

    U+00D4  LATIN CAPITAL LETTER O WITH CIRCUMFLEX

    U+00F4  LATIN SMALL LETTER O WITH CIRCUMFLEX

    U+0102  LATIN CAPITAL LETTER A WITH BREVE

    U+0103  LATIN SMALL LETTER A WITH BREVE

    U+01A0  LATIN CAPITAL LETTER O WITH HORN

    U+01A1  LATIN SMALL LETTER O WITH HORN

    U+01AF  LATIN CAPITAL LETTER U WITH HORN

    U+01B0  LATIN SMALL LETTER U WITH HORN

Examples: Suppose your keyboard is mapped to have Vietnamese characters like A with circumflex available. Then:

^V Â ' (Ctrl-V A-circumflex apostrophe)
    enters the composite character U+1EA4 (A with circumflex and acute)

^V ~ Ô (Ctrl-V O-circumflex tilde)
    enters the composite character U+1ED6 (O with circumflex and tilde)

Ctrl-6 A
    enters U+00C2 (A with circumflex)

Alt-4 A
    enters U+1EAA (A with circumflex and tilde)

Ctrl-Alt-3 A
    enters U+1EB2 (A with breve and hook above)

Ctrl-Alt-3 O
    enters U+1EDE (O with horn and hook above)

Note: Since mined 2000.12, the usage of composite base characters in mined character mnemonics or accent prefix combinations as just described also works in non-UTF-8 text encoding mode (e.g. in VISCII or TCVN encoding).

  Thai

  Character sets
In addition to Unicode, mined supports the TIS-620 character set (with CP874 extensions). To view and edit a file in this encoding, select it from the Encoding menu (section "Thai"), or use the respective command line parameter -ET. See Character encoding flags for details.
Terminal: If your terminal runs this encoding, make sure to indicate this properly with an environment variable (LC_* / LANG). See Terminal environment for details.

  Input method
Mined provides a built-in Thai input method. Select the input method from the Input method menu.

  Accented character input support
Not yet implemented. Tell me if you have a proposal or preference for assignment of accent prefix functions to the keyboard.

Character handling support
This chapter describes mined features for character manipulation and display of characters and character properties. Unicode and CJK specific features are described in the respective chapters. Character input support is described separately in the subsequent chapter.

  Script highlighting
It may be desirable to distinguish characters in different script by displaying their glyphs in different colours. (This especially allows to distinguish easier between similar glyphs as they occur in Latin/Greek/Cyrillic scripts.)
Script highlighting is currently pre-configured for Greek and Cyrillic. It uses the terminal's 256-colour mode if available.
The scripts to highlight and the colour values to use can be configured at compile-time. See Mined configuration below.

  Combining characters
When editing text in Unicode or any encoding that contains combining characters, mined supports display and editing of combining and combined characters.

(Note: Terminal support for combining characters is auto-detected; additional command line options are available in case this fails.)
If mined operates on a terminal that handles combining characters, it offers two editing modes: combined or separated. They can be toggled by clicking the Combining display flag in the Mode indication flags area (right part of the top screen line), or by the menu entry "Options - Combined display"; separated display mode can also be selected by the command line option -c.

Combined display and editing mode (Combining display flag ç)
    Combined characters are displayed as intended (i.e., combined).

•   Micro movement into combined characters:

    •   The cursor can be moved into a combined character with Ctrl-cursor-left and Ctrl-cursor-right, or ^V cursor-left and ^V cursor-right.

    •   You can determine the exact position of the cursor if permanent character info is switched on (by HOP ESC u or with HOP "Toggle Char info" in the Options menu).

•   Partially editing combined characters:

    •   If the cursor is on a combined character, delete next character (e.g. Del on small keypad) will delete the whole combined character, with all combining accents.

    •   →NEW→ If the cursor is on a combined character, Ctrl-Del will delete only the base character, leaving combining accents which may then be combined with the previous character.

    •   If the cursor is within a combined character, delete next character will delete the current combining accent only.

    •   Ctrl-Backarrow or F5 Backarrow ("Delete single") behind or within a combined character will only delete the rightmost combining accent (preceding the cursor position) while Backarrow would delete the whole combined character.

    •   You can also position the cursor as described above and use copy-and-paste operations.
Note: Ctrl-cursor-left and Ctrl-cursor-right only work if these keys are configured to emit distinguished escape sequences with Control key held down. With xterm, this works by default. With rxvt, use the small keypad cursor keys, or enable Control on the right keypad with the sample configuration file Xdefaults.mined in the Mined runtime support library. With mlterm, enable this with the sample configuration file mlterm_key in the Mined runtime support library. Ctrl-Backarrow can also be configured to work with xterm but doesn't appear to work with rxvt or mlterm, use F5 Backarrow instead.

Separated display and editing mode (Combining display flag `)
    Combined characters are separated into base character and combining character(s) for display and editing. Combining characters are indicated with coloured background.

    •   In separated display mode, all cursor and text modification operations work on the combining parts as displayed.

Input support: For input of Unicode combining characters,
    see Combining character input below.

Note: Unicode combining characters (according to the
    most recent version of Unicode known to mined) that are not handled as combining characters by the terminal (which might implement an older version of Unicode) are always displayed like in separated display mode.

Note: Isolated combining characters, i.e. those
    appearing at a line beginning or after a TAB character, are always displayed like in separated display mode.

  Character information display
The command ESC u displays character encoding information in the bottom status line (conforming to ISO 14755); it displays the character code in the selected encoding (UTF-8 byte sequence in UTF-8 mode) and the ISO-10646 (Unicode) value of the current character, as well as Unicode script range and character category, width, and combining information. The Unicode value is displayed with 4 hexadecimal digits if the character is in the Unicode BMP (Basic Multilingual Plane, 16 bit), with 6 digits if it is a Unicode character outside of the BMP, and 8 digits if it is an ISO-10646 character outside of the Unicode range. The information displayed also indicates all kinds of encoding irregularities.
For the Unicode data version used for character properties see the mined change log.

Permanent display of character information is toggled with HOP ESC u or by selecting "Char info" in the Info menu (or with HOP "Toggle Char info" in the Options menu).

→NEW→ In the Info menu, attributes that are shown with the character information can be selected: Unicode script name, Unicode character name, Unicode character decomposition, list of input mnemonics.

→NEW→ Character information display can be selected with the +?c command line parameter (see parameter description for further options). To preselect continuous character information display, append +?c to the environment variable MINED.

  Han character information display
CJK-specific character information (semantic and pronuciation hints) is described below in section Han character information display.

  Character conversion features

  Case conversion
The case conversion functions (ESC C, HOP ESC C, F11, HOP F11, Shift-F3) cover the full Unicode range. They also handle special cases like Greek final sigma, optionally Turkish "i", case mapping to multiple characters, and Lithuanian special conditions. Japanese characters are toggled between Hiragana and Katakana by the same functions.
Shift-F3 cycles casing of a word between all small, title case (beginning capital), and all capitals. It handles title casing, using Unicode title case characters for the first character when appropriate. For Japanese script, it toggles the word between Hiragana and Katakana.
The case mapping is based on the most recent Unicode version compiled into mined (for the actual version see the mined change log and the Options menu About command). It is applicable in all text encodings.

  Numeric conversion
Commands are available to insert characters corresponding to a hexadecimal character code or hexadecimal/octal/decimal Unicode value contained in the text, to insert a respective value corresponding to the current character, →NEW→ or (Alt-x) to toggle the preceding character and its hexadecimal code. For details, see the section Code conversion in the Command reference.

  Numeric entity (HTML/URL) conversion
→NEW→ HTML numeric character entities (e.g. &x40; for @) or URL escape notation (e.g. %20 for space) can be converted into unescaped characters. Use one of the Mnemonic character substitution commands (ESC _ or national variants) described below.

  Mnemonic conversion
A character mnemonic at the cursor position can be replaced with its associated character. Use one of the Mnemonic character substitution commands (ESC _ or national variants) described below.

  Encoding conversion support
A special feature offers interactive conversion to or from Unicode character encoding, see Encoding conversion support in chapter Unicode support below.

  Unicode Copy/Paste buffer
The Copy/Paste buffer can be operated in Unicode mode in which case it converts between text edited in different character encodings. See Unicode Copy/Paste buffer conversion below.

  Smart quotes
Straight (double or single) quote characters «"» or «'» can be replaced automatically with an opening or closing typographic quotation mark, depending on the text context. Select the quotation marks style to be applied from the Smart Quotes selection menu (open with ESC Q or Alt-Q or right-click on the smart quotes indication in the flags area in the top screen line), or middle-click on the smart quotes flag to toggle between the current and the previous smart quotes style selected with the menu.
When a file is loaded, mined tries to determine the applicable quotation marks style in two ways: If mined edited the file before and noted the last cursor position (in the file @mined.mar, which can be created using the HOP F2 command, or the File menu "Save Position" command), this information also includes the last selected smart quotes mode for the file. If that information is not available, mined auto-detects existing quotation marks in the file and adjusts its smart quotes mode accordingly.
The smart quotes left/right selection algorithm considers the text context to automatically support smart quotes also in CJK text.
A typographic apostrophe can be inserted with HOP ' (^G ').
In smart quotes mode, straight quotes can be inserted with mnemonic compose pairs (^V ^ " or ^V ^ ' , or ^V "# or ^V '# respectively) or →NEW→ with Alt-' or Alt-" (works in xterm 214/216 or later (with modifyOtherKeys feature)).
Smart quotes are applicable in all text encodings provided the desired quote marks are contained in the selected encoding.
Smart quotes style can also be preselected with the environment variable MINEDQUOTES which should then contain the opening/closing quote pair or just the opening quote mark (UTF-8 encoded, double or single quotes); this overrides both auto-detection and the preference saved with the cursor position.

  Smart text replacements: smart dashes and arrows
If smart quotes are active, some other smart input text replacements are applied to sequently entered characters (unless during a repeat command entering multiple characters):

--  if preceded by a Space character: en dash (U+2013)
    otherwise: em dash (U+2014)

-   if an adjacent character is in the Hebrew script range: Hebrew hyphen mark Maqaf (U+05BE)

<-  leftwards arrow (U+2190)

->  rightwards arrow (U+2192)

<>  left right arrow (U+2194)

Character input support
Some character input support features support international scripts (especially with Keyboard Mapping and Input Methods), others mainly address composite characters. For the latter, it is useful to explain a few notions:

Combining character:
    A character (usually in Unicode) that is defined to combine with the previous character into a combined character, to be displayed as a single glyph (visual unit).

Combined character:
    The glyph combination of a Unicode character (base character) with one or more Unicode combining characters.

Composed character (or composite character):
    A character that has one or more accents composed into it, or is otherwise composed of components, like the ae ligature, to be displayed as a single glyph. It can be a single Unicode character or a Unicode combined character consisting of a Unicode base character and one or two Unicode combining characters.

Accented character (or diacritic character):
    A special case of a composite character where a letter is composed with one or more accents.

Compose key:
    A number of system and keyboard vendors have equipped their keyboards with a "Compose" or "Combine" key. This key - when configured and interpreted properly by the operating environment - produces a composed character which is then provided as input to the application.

  Accented and mnemonic input support
Function keys or character mnemonics can be used to enter accented or other composite characters. (This is also known as digraph function with some editors.)
These character composition functions also work on the prompt line.
(Any composite character configured on your keyboard can of course also be entered directly or using the Compose/Combine key of your keyboard.)

→NEW→
    Note that mnemonic input and accent prefix keys can be combined in flexible ways, e.g.

^V ' Ctrl-F6 e
    or

F6 ^V e ^
    which both enter U+1EBF (e with circumflex and acute)

→NEW→
    Mnemonic input can be applied recursively to compose a character for further composition, e.g.

^V ' ^V a e
    enters U+01FD (æ with acute)

→NEW→
    Accent prefix keys can use an already precomposed base character for further composition; if this does not match an explicitly known mnemonic, the base character is decomposed first to find a match, e.g.

F6 ü
    or

F5 ú
    which both enter U+01D8 (u with diaeresis and acute)

→NEW→
    Up to three accent prefix keys can be combined by entering them in sequence in order to compose characters with multiple accents, e.g.

F5 F6 u
    enters U+01D8 (u with diaeresis and acute)

Ctrl-2 Ctrl-7 a
    enters U+1EB1 (a with grave and breve)

Ctrl-- Ctrl-: u
    enters U+1E7B (u with macron and diaeresis)

Ctrl-, Ctrl-( e
    enters U+1E1D (e with cedilla and breve)

Alt-7 Ctrl-, < alpha >

Alt-F6 Shift-F6 Ctrl-, < alpha >

Ctrl-< Ctrl-` Ctrl-, < alpha >
    all enter U+1F82 (alpha with psili and varia and ypogegrammeni) where < alpha > indicates the Greek letter alpha, which may e.g. be entered by selecting the Greek input method and typing the "a" key

  Accent prefix keys

General notes on using keys with Control, Shift, Alt modifiers:
    Especially for accented character input, mined makes use of key combinations modified with Control, Shift, Alt, or a combination of them. Some of these key combinations may be limited by local environment, especially the window system, or may need extra configuration to be enabled.

    •   Hint on input of Alt/Ctrl-modified function keys: These are often intercepted by window systems for special functions.

        •   Alt: →NEW→ Alternatively to using the Alt key, the ESC key can be used as a prefix to a function key to achieve the same modified function, e.g. ESC F6 instead of Alt-F6. Note, however, that there is an ESCAPE delay (default 450 ms) during which the subsequent function key should be pressed.

        •   Control: →NEW→ Alternatively to using the Control key, Ctrl-V can be used as a prefix to a function key to achieve the same modified function, e.g. Ctrl-V F6 instead of Ctrl-F6.
    Specific advice:

    Window system
        suppresses
        remedy

    KDE Ctrl-Fn, Ctrl-Shift-Fn, Alt-Fn
        press the "Window key" additionally at the same time, e.g. Window-Alt-F6 or use ESC or Ctrl-V prefixes, e.g. ESC F6 (be fast!), Ctrl-V Shift-F5

    gnome-wm
        Alt-F5
        Window-Alt-F5 or ESC F5 (be fast!)

    fvwm2
        Alt-Fn
        ESC Fn (be fast!)

    Exceed
        Alt-Fn, Alt-Shift-Fn
        ESC Fn, ESC Shift-Fn (be fast!)
        or: configure ("Tools - Configuration... - Keyboard Input") "Windows Modifier Behavior - Alt Key:" and select "To X"

    •   Modified digit keys (e.g. Alt-2) as well as →NEW→ Ctrl-modified punctuation keys (e.g. Ctrl-;) are used as extended and intuitive accent prefix keys. To enable them, either use a recent version of xterm (216) or configure them with your terminal.
        Configuration instructions for older versions of xterm and for rxvt can be found in the sample file Xdefaults.mined in the Mined runtime support library.

    •   Note: In rxvt, Ctrl-modified and shifted punctuation keys (if enabled by configuration following the hint above) interfere with ISO 14755 input mode of rxvt; if the following key is entered twice, that mode is aborted and the modified punctuation key becomes effective as an accent prefix in mined.

    •   Warning: The Alt-F4 key combination should not accidently be hit as many window managers use it to kill the terminal window!

The following table lists the accent prefix keys:

F5  (Sun: R4/-) diaeresis (umlaut) / dialytika

Note: If your keyboard assignment provides its own accent prefix keys ("dead keys"), pressing the key twice usually delivers the corresponding spacing character which can then be used for the extended accent prefix functionality of mined; e.g. hold Control, then press ´ (acute key) twice, to invoke the acute/oxia prefix function of mined.

Note: For combining multiple accents, in most
    cases their order does not matter. As an exception, to combine dot above and macron, enter prefix keys in this order, as s macron and dot above will be interpreted as dot below.

dot macron
    e.g. Ctrl-. Ctrl-- dot above and macron (on A or O)

macron dot
    e.g. Ctrl-- Ctrl-. dot below

Note: For the sake of accepting Ctrl--
    intuitively both as an accent prefix for macron as well as an accent modifier to place an accent below a letter, the macron accent prefix combined with another accent prefix key is also interpreted as applying that accent below. As a workaround to ambiguous cases, it has to be applied twice with diaeris for diaeresis below (U), and three times for line below.

macron macron diaeresis
    e.g. Ctrl-- Ctrl-- Ctrl-: diaeresis below

macron diaeresis
    e.g. Ctrl-- Ctrl-: macron and diaeresis

diaeresis macron
    e.g. Ctrl-: Ctrl-- diaeresis and macron

macron macron macron
    e.g. Ctrl-- Ctrl-- Ctrl-- line below

Note: Some accent prefix keys, when applied twice in
    sequence, are mapped to a single accent as follows:

acute acute
    e.g. F6 F6 double acute accent

grave grave
    e.g. Shift-F6 Shift-F6 double grave accent

macron macron
    e.g. Ctrl-- Ctrl-- bar/topbar

cedilla cedilla
    e.g. Ctrl-, Ctrl-, psili/comma below

  Combining character input

Unicode combining characters can be entered
    by applying accent prefix keys to the Tab key. They will be visually combined with the previous character by rules of Unicode (and by terminal implementation). Examples:

Ctrl-, Tab
    combining cedilla

F6 F6 Tab
    combining double acute accent

  Special character input shortcuts

Typographic quotation marks can be entered
    by applying accent prefix keys to the space key as follows, or using certain input mnemonics or shifted combinations (see below):

(twice) grave space
    (double) left quotation mark

(twice) acute space
    (double) right quotation mark

acute space
    e.g. F6 space or Ctrl-' space also serves for input of typographic apostrophe (or HOP ')

(twice) cedilla space
    (double) low-9 quotation mark

(twice) dot above space
    (double) high-reversed-9 quotation mark

^V < < or ^V > >
    double angle quotation marks « »

^V < space or ^V > space
    single angle quotation marks

Alt-'
    plain single quote mark (U+27)

Alt-"
    plain double quote mark (U+22)

Some characters are specifically mapped to special key
    combinations or specific applications of accent prefix keys for convenience or for Windows compatibility:

Ctrl-Shift-space
    no-break space (U+00A0)

Ctrl-@ a/A
    å/Å

Ctrl-& a/A
    æ/Æ

Ctrl-& o/O
    oe/OE ligature

Ctrl-& s
    ß

Ctrl-?
    ¿

Ctrl-!
    ¡

As with modified keys in general, these shortcuts may depend on proper terminal configuration according to the sample files in the Mined runtime support library.

  Character input mnemonics
The enter-control-code prefix (^V, or ^Q in emacs mode, or ^P in WordStar mode) can be used for mnemonic character composition. This covers accented characters and other mnemonics. The available mnemonics include RFC1345 mnemonics (extended to provide generic accent mnemonics for Unicode characters), mnemonics known from HTML and TeX and useful supplementary mnemonics. See Character Mnemos reference on the mined web site for a listing.
With mined 2000.10, supplementary character mnemonics have been revised and made consistent with generic RFC1345 mnemonics, redundant mnemonics have been removed, and coverage of all Latin characters (esp. with multiple accents) has been completed.

For accent compositions, mnemonic patterns (generic accent mnemonics) are listed in the following table; the respective letter to place the accent(s) on is indicated with an "x" below.

For Greek and Cyrillic accented characters, mnemonics combining accents with Greek or Cyrillic base characters are generated automatically from the UnicodeData.txt database.
Greek and Cyrillic accent prefix keys reuse those for Latin accents and are listed in the sections on Greek and Cyrillic script support (see Language support).

See also the description of the ^V function below for more input options.
Two-letter mnemonics can also be entered in reverse order if this is unambiguous. Detection of reverse order mnemomics (two letters or one letter and multiple accents) as well as the generic accent mnemonics " ^ ` ~ ¨ ¯ ´ ¸ ° (which are available for convenience in addition to the less intuitive > ! etc.) works with both short mnemonic entry (two-letter "^Vxy") →NEW→ and full mnemonic entry ("^V xy... ").

Mnemonic character substitution commands (ESC _ and national variants) replace characters at the cursor position with the respective character described by them. The following substitute descriptions are detected:

    •   Two-character mnemonic

    •   HTML character mnemonic

    •   HTML numeric character entity

    •   URL escape notation (bytewise hexadecimal with % prefixes)

  Keyboard Mapping and Input Methods
Mined supports optional keyboard mapping which is especially useful for Unicode or CJK editing. When a keyboard mapping is selected, input characters or sequences are transformed to other characters or sequences, typically of a certain Unicode script range.
Keyboard mappings for Greek, Cyrillic, Hebrew, Arabic, and major CJK input methods are preconfigured (they have been ordered in the Input Method menu according to the order of their respective basic ranges in the Unicode character set, or to the order of the letters of the usual abbreviation CJKV for East Asian text processing - Chinese, Japanese, Korean, Vietnamese). The Radical/Stroke input method provides additional functionality as a special case.
Mined provides compile-time configuration of additional input methods; for this aim, further mappings can be generated using the mkkbmap script (from tables in various formats as used by other editors or →NEW→ supplied by the m17n multilingualization package) and then compiled into mined. See Mined configuration below for details.

Keyboard mapping works as follows: You enter a key sequence that is mapped to a character sequence in the selected keyboard mapping table. The transformed character sequence is used as input.
As some typical keyboard mappings contain ambigous key sequences where one may be a prefix of another, a short delay is applied in these cases to allow recognition of any such sequence to be mapped. After a timeout, the shorter sequence already matching will be used; the timeout can be cut short by typing a Space key, the Space character itself will then be discarded. (The timeout value is 900 ms by default and can be configured with the environment variable MAPDELAY.)

  Pick lists
Some keyboard mappings, especially for CJK input methods, contain multiple choice mappings. In these cases, a selection menu is displayed that offers a "pick list" to select a character from. A character can be picked with a mouse click, or by navigation to the desired choice with the cursor keys (down/up, right/left, page down/up) or the '<'/'>' keys , or by just selecting the menu row first (cursor-up/down), then typing a digit 1-9 or 0 to select the numbered character.
The Space key can be configured to either navigate to the next choice, the next row, or to select the current choice; see option -K.
If the pick list is too large to fit on the screen, the menu will be scrollable or pageable (using cursor keys).

While navigating through the pick list, the line and the selected item in the line are highlighted accordingly; if the current item is a CJK character, also its character information (description and optionally pronunciations as configured with the Han info option of the '?' information flag menu) is displayed on the status line. If the item is a word comprising multiple CJK characters, the information for only the first of them is shown. The available information is derived from the Unihan database.

Keyboard mapping data are based on Unicode. So in CJK text mode, the selection menu (the pick list) may contain symbols that are not mapped to the active CJK text encoding. In a UTF-8 terminal, these will still be displayed but cannot be inserted. In a CJK terminal, some characters may not be displayed; an empty entry is shown instead. (In a non-Unicode, when editing text in a different encoding, there may even be characters that cannot be displayed in the selection menu but can be inserted.)

  Input method selection
An active and a standby input method (keyboard mapping) are maintained. They can be toggled quickly for text input, also on the prompt line.
The current mapping is indicated as the Input Method flag by its two-letter script tag in the flags area, showing "--" if no mapping is active.

The active mapping can be selected in the following ways:

ESC k or Alt-k or Alt-F12 or left click on Input Method flag
    toggles between current (active) and previously selected (standby) input method (keyboard mapping)
    (Alt- toggle functions also work on prompt line)

HOP ESC k (or HOP Alt-k)
    clears input method, i.e. resets keyboard mapping to none (unmapped input)

ESC I or Alt-I or ESC K or Alt-K or Ctrl-F12
    opens the Input Method (Keyboard Mapping) selection menu
    (Alt-I or Alt-K or Ctrl-F12 also work on prompt line)

right click on Input Method flag
    opens the Input Method selection menu

HOP ESC K or HOP Alt-K
    cycles through available input methods / keyboard mappings

Note: For preselecting the active or standby input method by environment configuration, see about usage of the environment variable MINEDKEYMAP below.

Note: Keyboard mapping is implicitly suppressed temporarily where it is not useful: during mnemonic character input, HTML marker input, command letter entry, help selection, yes/no prompting.

Character encoding support
A character encoding for interpretation and handling of text is selected in one of the following ways:

    •   One of the command line options -E... with a number of options to specify the desired text encoding (see the encoding options above).

    •   From the Encoding Menu (one of the flag menus), the encoding interpretation can be changed while editing; to open it, click with the right mouse button on the encoding indication in the flags area of the top line, or type Alt-E. See also Mode indication flags for an overview. To toggle between the current and the previously selected encoding, click the Encoding flag with the left mouse button.

    •   Auto-detection (by heuristic counting of valid character codes). Note: The encodings to be taken into account for auto-detection can be configured with the MINEDDETECT environment variable. Set it to the desired list of single-letter encoding indications to disable auto-detection of other encodings. Recognised encoding indications are mentioned in the list of auto-detected encodings below (they are the same as used with the -E parameter). UTF-8 auto-detection cannot be disabled this way.

    •   Locale indication in environment variables (see Locale configuration), especially the variable TEXTLANG which does not affect the locale-related assumption of terminal encoding.

  Auto-detected character encodings
The following encodings are auto-detected unless overridden with a -E command line option (or -l or -u):

-   UTF-8

-   UTF-16 encoding (big or little endian) with or →NEW→ without BOM (byte order marker)

8   any 8 bit encoding; this is auto-detected in a generic way; the actual 8 bit encoding assumed corresponds to the terminal encoding if it is an 8 bit terminal; otherwise, Latin-1 is assumed; using "8" in the environment variable MINEDDETECT excludes all CJK encodings from auto-detection (but not UTF-8), and adds all 8 bit encodings that are not included by default

L   Latin-1 (ISO 8859-1)

W   Windows Western ("ANSI", CP1252)

P   PC Latin-1 (CP850)

M   MacRoman

-   CJK encoding (with unspecified mapping) is pre-auto-detected in a generic way; usually the actual CJK encoding is determined, too

G   GB18030

B   Big5

J   EUC-JP

S   Shift-JIS

K   UHC

V   VISCII

  CJK and mapped 8 bit encoding support
Mined supports major CJK encodings as well as mapped 8 bit encodings ("character sets"). Mined has built in support for a large number of 8 bit encodings which appear to be in use or unique for a region. The Encoding menu has been structured with sub-menus to provide a concise menu selection feature.

  Combining characters
In all character encodings handled by mined that contain combining characters, mined handles them and provides partial editing and an optional separated display mode as described above in section Combining characters. (CJK encodings EUC-JP, Shift-JIS and GB18030, Vietnamese TCVN and Thai TIS-620, ISO Arabic, Mac Arabic, ISO Hebrew, Windows Hebrew). Handling of combining text characters is properly coordinated with the set of combining characters supported by the terminal.

For Japanese, the JIS characters that map to two Unicode characters are supported.

  Character code related commands
The command ESC u displays character encoding information in the bottom status line (conforming to ISO 14755); this includes the character code, the mapped Unicode character value, script and character category, and combining information. See Character information display for details.
With HOP ESC u, permanent display is toggled.

Other commands insert the code of the current character, insert a character taking its character code or Unicode value from the text, →NEW→ or toggle the preceding character and its hexadecimal code (Alt-x). For details, see Code conversion in the Command reference.

  Terminal environment for CJK encoding support
Mined supports handling of CJK text encoding in any terminal (see Terminal encoding support below). However, proper display of a wide range of CJK characters can obviously only work in either a Unicode terminal (recommended) or in a native CJK terminal that runs the same encoding as the selected text encoding.

CJK terminals: For terminals that support native CJK encodings (e.g. cxterm, kterm, hanterm), the terminal encoding assumed by mined can be specified with a command line option or by proper locale indication in one of the environment variables LC_ALL, LC_CTYPE or LANG. For available encodings, see Mode indication flags. For usage of the +E options, see the description of the Terminal encoding options above. For usage of the locale environment variables, see Locale configuration.

Note: In native CJK terminals, it is often troublesome to find a working encoding configuration and font setup, and the locale environment is not automatically set by the terminals. A collection of wrapper scripts is available ( http://towo.net/mined/terminals.tar.gz) to help with this setup problem and demonstrate the invocation of a number of different CJK and 8 bit encoded terminal windows, along with selection of suitable fonts and proper locale environment setting.

Note: Native CJK terminals have a different assumption of the range of character codes supported in an encoding family, e.g. Big5 / Big5 with HKSCS, GB2312 / GBK / GB18030, EUC-KR / UHC, EUC-JP without/with 3 byte codes. For compact handling, mined always assumes the largest superset of these encoding families. It does, however, have some features to prevent display garbage in most cases when a terminal supports a smaller character set: By default, mined does not display the following CJK character codes in a native CJK terminal, i.e. it displays a substitute indication for them (see CJK character display above):

    •   Unknown characters: CJK characters that have no defined mapping to a valid Unicode character. Use the +C option to override this display suppression and enforce transparent display of unknown characters in a CJK terminal.

    •   Invalid characters: CJK characters that do not match the encoding scheme (e.g. wrt. to specified byte ranges) of the selected encoding. Use the +CC option to override this display suppression and enforce transparent display of invalid character codes in a CJK terminal.

    •   Extended characters: CJK characters encoded with 3 or 4 bytes. Use the +CCC option to override this display suppression and enforce transparent display of extended character codes in a CJK terminal.

Regardless of all these features and options, it may not always be possible to prevent display garbage, especially if the font used by the terminal does not cover the needed character range. To avoid these problems in general, it is recommended to use a Unicode terminal for editing CJK encoded files.

See also Terminal interworking problems for special hints about certain terminals.

Unicode support

  Introduction: handling Unicode encodings
Mined interprets UTF-8 which is a multi-byte character encoding of the ISO-10646 character set, part of which is also known as Unicode. When reading a file, it detects UTF-8 encoding automatically (unless overridden by explicitly selecting a text encoding with a command line option -u or -l or -E...). It can also edit UTF-16 encoded Unicode files (UTF-16 can represent the complete 21 bit Unicode subset of ISO-10646). UTF-16 big or little endian with or without BOM (byte order mark U+FEFF) is auto-detected or can be selected with a command-line option (see notes under Locale configuration below).
UTF-16 is maintained transparently, i.e. a UTF-16 encoded file is written back in UTF-16, and if it was beginning with a BOM this is maintained. No explicit UTF-16 entry exists, however, in the Encoding menu since the text is internally handled in UTF-8. However, the character encoding flag indicates UTF-16 file encoding with either "16" (big endian) or "61" (little endian).

  UTF-8 internal representation, transparent handling of other text
Mined handles UTF-8 representation internally and also edits and keeps illegal UTF-8 sequences. This way, if you happen to open a Latin-1 or CJK or any other encoded file in UTF-8 mode, or switch encoding while editing, or edit a file with mixed encoding, the text contents can still be edited and you will not loose any file contents information.

  Character encoding indication
The upper-right flags area has a character encoding indication which shows "U8" if UTF-8 text interpretation is selected. For Latin-1 text interpretation "L1" is shown, for others see Mode indication flags. You may click on the indication flag to toggle between the current and the previous selected encoding.

  Character information display
The Character information display command ESC u is described above; character information display can also be preselected by environment configuration. In UTF-8 mode, information shown includes the UTF-8 encoding byte sequence.

  Character input support
With ^V, mined's special character input support is invoked (both while editing text and entering text on the prompt line, e.g. as a search expression). With this feature, (in addition to plain control characters) a composite character can be entered by its accent combination or other mnemonic character description; a more-than-two letter character mnemonics would be embedded in space characters after the ^V. In addition, numeric character codes or values can be entered with leading ^V#, octal/decimal with ^V##/^V#=, Unicode with optional u/U/+. (For examples, see description of the ^V function below.) With numeric character input, mined supports successive multiple character entry according to ISO 14755; if the numeric code is terminated by a Space key, another numeric character can be entered subsequently; an Enter key terminates numeric character input.

See also the generic section Character input support above for input support for accented characters and keyboard mapping.

  Encoding conversion support
Two functions support interactive character encoding conversion (Latin-1 to UTF-8 or UTF-8 →NEW→ to current encoding) to partially fix files with mixed encoding. In either text encoding mode, the search function looks for characters encoded in UTF-8 (when not editing in UTF-8 mode) or not (when editing in UTF-8 mode); the command is HOP ESC ( or Alt-F11 . Then, convert the character with ESC _ or its national variant (see mnemonic character substitution commands in the Command reference).
For repeated interactive conversion, both functions can be combined into Alt-Shift-F11 (convert current character, then search next).

  Unicode Copy/Paste buffer conversion
For the Copy/Paste buffer, Unicode mode can be selected which maintains its contents always in Unicode, so that Copy/Paste of text works between differently encoded files (or sections of a file, if encoding is switched while editing) with automatic character code conversion. This mode is only effective while editing with non-Unicode encoded text interpretation.
Select this mode with the command line option -Eu or in the Paste buffer menu (righ-click on the Buffer mode flag "=" or "+") and select "Unicode".
Unicode buffer mode is indicated by cyan background of the Paste buffer flag (then "=" or "+"), except in Unicode text mode.

  Smart quotes and dashes
If smart quotes mode is enabled (see the Quotes style menu under the Quotes flag left to the Encoding flag and menu), quote mark keys will enter typographic smart quotes instead. Smart dashes also apply. See Smart quotes above for more details.

  Bidirectional terminal support
A bidirectional terminal (such as mlterm) will probably also apply Arabic LAM/ALEF ligature joining. Mined auto-detects this feature and enables bidi terminal handling automatically. Otherwise, bidi terminal handling can be configured with the option +UU.
In this mode, when displaying a menu, underlying text lines that contain right-to-left characters are cleared first in order to prevent display confusion between the terminal's bidi algorithm and the menu position.
Also, with bidi terminal handling enabled, mined assumes that the terminal applies Arabic LAM/ALEF ligature joining and properly accounts for this feature in display position handling.
In separated display mode, the joining part of the ligature is indicated similar to the handling of combining characters.

  Input support for right-to-left scripts ("poor man's bidi" mode)
This support feature for input of right-to-left text pieces is enabled by default unless the terminal is detected to be in bidi mode itself (e.g. mlterm). "Poor man's bidi" mode is intended for quick entry of right-to-left text without having a right-to-left terminal; it is similar to the "revins" (reverse insert) option of vim and works as follows:
After entering a right-to-left Unicode character, the cursor position is moved left of it, so subsequent characters will be appended left and the text shifted right. Characters are stored in visual order while input support is implicit, based on the characters being typed. Entering a left-to-right character will automatically skip behind the previously entered right-to-left text on the line (changed in mined 2000.10) and switch to left-to-right direction; this behaviour optimises inserting small pieces of right-to-left text into basically left-to-right text; this priority is justified by the assumption that this mode (with visual storing order) is only useful for inserting small right-to-left quotations into left-to-right text and not for editing right-to-left documents (which should be stored in logical order).
Newline, Space, Tab, and combining characters attempt to behave well according to what was entered before; however, intermediate cursor movement is not considered.

  Unicode line ends
Mined detects and handles Unicode line separators and paragraph separators (unless disabled with +u-u). They are displayed as shown above. →NEW→ Interpretation of these characters as line ends is disabled if a file is explicitly opened in non-Unicode encoding (but not if non-Unicode encoding is just auto-detected).
HOP Enter will insert a Unicode paragraph separator, Enter in a line that already has a Unicode line end will insert a Unicode line separator. Also the keys Shift-Enter or Ctrl-Enter insert a paragraph separator or line separator respectively.
Configuration: In order to enable shift and control with the Enter keys, xterm or rxvt must be configured as shown in the example configuration file Xdefaults.mined in the Mined runtime support library.

  Unicode display
In UTF-8 terminal mode, mined displays all Unicode characters if they are contained in the font used by the terminal. Fonts usually have a substitute glyph to indicate characters not contained in the font. Wide characters (double-width glyphs) are displayed in a double-width character cell of the terminal. Combining characters are displayed either combined or separated (see Combining characters below).

Illegal UTF-8 sequences are displayed with highlighted background, using the following indications. Furthermore, control characters encoded as a UTF-8 sequence and control characters in the "C1" range (values 0x80..0x9F) will be displayed similar to normal control characters but with coloured highlighting.

8   for an unexpected UTF-8 continuation byte (range 80-BF)

4   for a 0xFE (254) byte

5   for a 0xFF (255) byte

«   for a too short UTF-8 sequence if followed by a single-byte character (00..7F)

»   for a too short UTF-8 sequence if followed by a multi-byte character (C0..FF)

→NEW→ Illegal or non-Unicode characters are indicated with the following replacements:

&#65533;
    (or ? or []) a character code ending with FFFE or FFFF (override substitution for transparent display with +C)

&#65533;
    (or ? or []) a surrogate code point (override substitution for transparent display with +CC)

&#65533;
    (or ? or []) a code point outside the defined Unicode range (override substitution for transparent display with +CCC)

  Character substitution display
Legal characters (in the effective text encoding) that cannot be displayed in a non-Unicode terminal are indicated with the following replacements:

¤ or
    ¤ (if wide) a non-combining Unicode character that cannot be displayed

% or
    % (if wide) (if the terminal cannot display ¤) a non-combining Unicode character that cannot be displayed

' or
     ' a Unicode combining character that cannot be displayed

E   the Euro character U+20AC

"   a quotation mark character (typographic quote mark)

-   a dash character

e, ê,
    etc →NEW→ a combined or other character that cannot be displayed which is based on the displayed character by its Unicode decomposition

0 ..9 ,
    A ..Z etc a corresponding fullwidth ASCII character

Configuration: Display colour of special or illegal UTF-8 indications can be changed with the environment variable MINEDUNI, the value should be the numeric part of an ANSI terminal control sequence; optionally, the value can be preceded by a character to be used for Unicode character indication in non-Unicode terminal mode.
(The default configuration value is "¤ 46").

  Combining and joining characters
Mined supports handling of combining characters, featuring optional separate display and partial editing, as described above in section Combining characters.

  Joining characters
If mined assumes that the terminal applies LAM/ALEF ligature joining (either configured with the +UU right-to-left display option or auto-detected), the joined character width will be handled correctly in cooperation with the terminal.
Mined supports ligature joining in both combining character display modes:

    •   In combined display mode, the screen position is accounted properly. →NEW→ Also, when deleting a character, a joined ligature is deleted together with the base character, just like combining characters.

    •   In separated display mode, the joining part of the ligature is indicated using the appropriate isolated form, highlighted with Unicode special indication background colour (similar to the handling of combining characters).

  Search expression limitations
Unicode search ranges can not be very large as all included characters are listed in an internal buffer which is limited to ca. 1 KB.

  UTF-8 preservation and byte-transparent editing
When splitting lines that are too long for internal handling, consistency of UTF-8 sequences is preserved (they are not split); combining characters may get split off their base characters, however, they will join seemlessly as lines are joined again (e.g. when saving the file). Note that combining characters at the beginning of a line are not displayed in combined display mode.

  Terminal environment
Unicode text can be edited in any terminal encoding (UTF-8, 8 bit, CJK), however, a UTF-8 terminal is preferable. UTF-8 terminal operation can be configured in either of these ways:

    •   Auto-detection: If the terminal emits cursor position reports, mined can uniquely recognise UTF-8 terminal encoding and further UTF-8 features (see Terminal encoding support below).

    •   Environment: By proper environment variable settings. For more details, see Locale configuration.
        Note: In general, it is advisable to start a terminal window using a wrapper script that sets a suitable locale environment at the same time, in order to support all kinds of applications that are more dependent on proper environment setting than mined is. The mined installation also provides the script uterm for this purpose, with its own manual page. (In case uterm is not installed, it is also included in the Mined runtime support library.)

    •   Parameter: +EU selects UTF-8 terminal mode.

See also Terminal interworking
    problems for special hints about certain terminals.

CJK support (Chinese/Japanese/Korean Han character features)
Mined provides CJK support features uniformly in Unicode and in major CJK encodings. For information relating to CJK character encoding see Character encoding support below.

  CJK input method support
Input methods for CJK characters are supported with the keyboard mapping mechanism. A number of popular input methods for CJK text input are pre-configured, others can be added at compile-time with the mkkbmap script.

  Radical/Stroke input method
Mined provides a Radical/Stroke input method for CJK characters with specific functionality in addition to keyboard mapping; it works at two-levels, selecting a radical first, then a character from a list sorted by stroke count. If this input method is active, a selection menu for the 214 CJK radicals is displayed (without prior keyboard input). The menu displays all variations of each radical. After selecting a radical from this menu, a second-level menu is displayed, showing all CJK characters based on the selected radical, sorted by the number of strokes. Many of these menus will not fit on the screen and can be scrolled. Pressing Escape here would return to the radical menu; pressing Escape there would disable the input method. To enter a non-mapped character (e.g. a line end), you need to disable Radical/Stroke input method temporarily; just toggle it back on with Alt-k (or Esc k) or Alt-F12 and the radical menu will be displayed again for continued input.
For the Unicode version used as the character data source, see the mined change log.

  CJK character display
Combining characters (in both JIS encodings and GB18030) are handled and the combined characters are displayed properly in either combined or separated display mode in a UTF-8 terminal (like for UTF-8 encoded text). The following special CJK character indications apply:

¤   CJK character that cannot be displayed in (8-bit) terminal

% or
    % CJK character that cannot be displayed in (8 bit or CJK) terminal because the terminal encoding does not support it

' or
     ' CJK combining character that cannot be displayed in (8-bit) terminal

? or
    ? CJK character code that has no known mapping to Unicode
    (to enforce display on CJK terminal use option +C)

# or
    # invalid CJK character code that is outside of the code range assigned to the encoding scheme
    (to enforce display on CJK terminal use option +CC)

#   CJK character in extended code range (esp. 3 and 4 byte codes, or codes with 0x80...0x9F byte range) that cannot be displayed on CJK terminal due to terminal capability limitations
    (to enforce display on CJK terminal use option +CCC)

<   incomplete or otherwise illegal CJK code

  Han character information display
When the cursor is on a Han character and either descriptive or pronunciation information about this character is available in the Unihan database (from unicode.org), mined can optionally display this information, with a selection of display details which may include semantic information and various pronunciations.
To enable Han info, select it in the Info menu. To open the Info menu, type Alt-F10 or right-click the "?" flag.
The information can optionally be shown on the status line (where it may be truncated if too long) or in a pop-up menu next to the character.
Pronunciation information to be displayed can be selected in the Info menu. →NEW→ While selecting multiple pronunciation options, the menu stays open.

The same information is always shown while you are browsing an input method pick list (then on the status line).

→NEW→ Han character information display can be selected with the +?h command line parameter (or +?x for short display on the status line). To preselect continuous Han character information display, append this parameter to the environment variable MINED.

The information includes the character code (in CJK encoding, both CJK code and corresponding Unicode value are shown). The amount of descriptive information (from the Unihan database) to be shown can also be preconfigured with the environment variable MINEDHANINFO; see Han info configuration below.
(For the Unicode version used for the Unihan data source, see the mined change log.)

Terminal encoding support
Mined supports UTF-8 terminals, CJK terminals, Latin-1 and other 8-bit encoded terminals.

  Terminal feature detection
Mined performs auto-detection of a number of terminal features:

    •   For UTF-8 terminals, mined performs auto-detection of terminal features (detection of UTF-8 terminal, different width data and combining data versions, handling of double-width, combining and joining characters).

    •   For CJK terminals, mined performs some auto-detection of specific CJK terminal features (handling of non-EUC code points, handling of extended code range, GB18030, 3-byte and 4-byte encodings, detection of kterm JIS encoding, detection of rxvt emulating CJK encoded terminal, special CJK width properties, and terminal support of combining characters).

    •   For mapped 8-bit terminals, mined performs auto-detection of terminal support of combining characters.

    •   For the Unicode version used for width and combining character properties, see the mined change log.

    •   CJK terminals cannot always be distinguished from 8-bit terminals by auto-detection. Neither can the encoding of either CJK or 8-bit terminals be auto-detected. It is thus advisable to setup proper settings of locale environment variables (LC_ALL, LC_CTYPE, LANG). Alternatively, the effective terminal encoding can be indicated to mined with a command line option (+EX). For configuration details, see Locale configuration below.

  Specific terminal properties
For more specific configuration hints (especially for PC-based terminals), and for description of the handling of certain terminal interworking problems, see the Terminal environment configuration hints below.

Mined Command reference (command and key function assignments)
General note on using keys with Control, Shift, Alt modifiers:
    Mined makes use of many key combinations modified with Control, Shift, Alt, or a combination of them, as a resource for invoking a larger number of specific functions, providing modified functionality as well as accented character input support. Some of these key combinations may be limited by local environment, especially the window system, or may need extra configuration to be enabled.
    Especially modified function keys are often intercepted by window systems for special functions.
    In general, mined interprets an ESC prefix as an alternative for an Alt-key combination. For further advice and window system specific hints on further remedies, as well as configuration hints, to enable modified key input see the hint box under Accent prefix keys above.

  Accented character input support by accent prefix keys

Mined defines a number of function keys, modified function keys,
    modifed digit keys, and →NEW→ modified punctuation keys for single and multiple accent composition with a subsequently entered character; for a detailed listing and description, see Accent prefix function keys above.
    →NEW→ Up to three accent prefix keys can be combined by entering them in sequence in order to compose characters with multiple accents. These functions also work on the prompt line (e.g. to enter search expressions).

F5 < character >
    Compose character with diaeresis (umlaut accent), e.g. a » ä

Shift-F5 < character >
    Compose character with tilde, e.g. a » ã

Ctrl-F5 < character >
    Compose character with ring or with cedilla, e.g. a » å , c » ç

Ctrl-Shift-F5 < character >
    Compose character with ogonek.

Alt-Shift-F5 < character >
    Compose character with breve.

F6 < character >
    Compose character with acute accent (accent d'aigu), e.g. a » á

Shift-F6 < character >
    Compose character with grave accent, e.g. a » à

Ctrl-F6 < character >
    Compose character with circumflex accent, e.g. a » â

Ctrl-Shift-F6 < character >
    Compose character with macron.

Alt-Shift-F6 < character >
    Compose character with dot above.

Ctrl-0 ... Ctrl-9
    Compose character with accent, esp. for Vietnamese accented characters.

(Ctrl-)Alt-1 ... (Ctrl-)Alt-5
    Compose character with two accents, esp. for Vietnamese double accented characters.

(Ctrl-)Alt-6 ... (Ctrl-)Alt-8
    Compose character with two accents for Greek multiple accented characters.

Ctrl-< punctuation key >
    →NEW→ Compose character with accent (looking similar to the modified punctuation character, e.g. Ctrl-, composes with cedilla, Ctrl-: with diaeresis, Ctrl-minus with macron, Ctrl-( with breve, Ctrl-< with caron, Ctrl-/ with stroke, Ctrl-; with ogonek, etc; see Accent prefix function keys above for details).

  Input support commands

Ctrl-V special input support
    These functions also work on the prompt line (e.g. to enter search expressions).

^V < control character >
    Enter control character.

^V [ or ^V \ or ^V ]
    Enter one of the control characters ^[, ^\, ^].

^V ^ ^ or ^V _ _
    Enter one of the control characters ^^, ^_.

^V ^ ' or ^V ^ "
    Enter one of the plain quote marks ' or " (needed in smart quotes mode)

^V < accent > < character >
    Compose accented character.

^V # xxxx < Space or Enter >
    Enter character defined by a hexadecimal number being input (depending on applicable encoding, byte value, Unicode value, or valid CJK code is required).

^V # # xxxxxx < Space or Enter >
    Like ^V # but using an octal number.

^V # = xxxxx < Space or Enter >
    Like ^V # but using a decimal number.

^V # u or U or +
    (followed by a numeric input as described above, with optional # or = for octal or decimal input) interprets the input as a numeric Unicode value which is converted into the current text encoding.

^V # ... Space ...
    With numeric character input, mined supports successive multiple character entry according to ISO 14755 if the numeric code is terminated by a Space key.

^V < function key >
    This is not an input support function but rather the function key is invoked as if pressed together with the control key.

Mnemonic character input support
    Mnemonics recognised include the following:

    •   RFC 1345 mnemos (except mappings to Unicode private use areas); in ambiguous cases, the RFC 1345 mnemos must be entered in long mnemonic input mode, e.g. with "^V pi " rather than "^Vpi".

    •   HTML mnemos; in ambiguous cases, the HTML mnemos must be prepended with a "&".

    •   TeX mnemos (macros) and substitutes, leaving out any "\".

    •   Supplementary mnemos as listed on the mined character mnemos page.
Unless there is an ambiguous mapping, all two-letter mnemonics can also be entered in reverse order.

^V < Space > < name > < Space or Enter >
    Lookup character mnemonic and enter character. RFC 1345 mnemonics take precedence in ambiguous cases.

^V < character > < character >
    Compose two characters. Non-RFC 1345 mnemonics take precedence in ambiguous cases.

Note:
    →NEW→ A number of mnemonics are defined with already precomposed base characters (especially for Vietnamese input) which can be used for further composition.
    ^V can be applied recursively to compose a character for further composition.
    See examples with æ below for both cases.

Examples:

^V^A
    Enter Ctrl-A.

^V^[ or ^V[
    Enter the escape character.

^V__
    Enter Ctrl-_.

^V'e
    Enter é (e with accent d'aigu).

^Vae
    Enter æ (the ae ligature).

^V ae'  (terminated by Space or Enter)
    Enter U+01FD (æ with acute).

^Væ'
    Enter U+01FD (æ with acute).

^V ^Vae'  (terminated by Space or Enter)
    Enter U+01FD (æ with acute).

^V'^Vae
    Enter U+01FD (æ with acute).

^VOK or ^Vcm
    Enter the check mark &#10003; (U+2713)

    Enter the character with hexadecimal value 20AC (which is the Euro character in UTF-8 encoding).

^V#U20ac (terminated by Space or Enter)
    Enter the Euro character (which has the hexadecimal Unicode value 20AC) encoded in the currently selected text encoding.

^V#+20ac < Space > +20ac < Enter >
    Enter two Euro characters in successive multiple character entry mode (ISO 14755).

  Input method (Keyboard mapping) selection

ESC k or Alt-F12 or middle click on Input Method flag (mapping indication in flags area)
    toggles between current and previously selected input method (or initially the configured standby input method) Note: (Alt-k or Alt-F12 also works on prompt line)

HOP ESC k
    clears input method, i.e. resets keyboard mapping to none (unmapped input)

ESC I or ESC K or Ctrl-F12 or right click on Input Method flag (mapping indication in flags area)
    opens the Input Method selection menu Note: (Alt-I or Alt-K or Ctrl-F12 also works on prompt line)

HOP ESC K
    cycles through available keyboard mappings / input methods

  Modifying text

Note on character deletion
    In order to accommodate various common ways of assigning control character codes to the Del and Backarrow keyboard keys, mined adjusts its own function assignment to the environment setting of the terminal interface, see Automatic backspace mode adaptation. (The ASCII DEL control character can be enforced to delete a character left with the option -B.)

Note on the Del key
    Many people expect the "Home" and "End" keys to move the cursor to the beginning or end of line, respectively, and the "Del" key to delete the next character. In the keyboard usage approach of mined, this is a waste of keyboard resources as these functions can easily and quite intuitively be invoked with "HOP left" and "HOP right", i.e. by pressing the keypad keys "5 4" or "5 6" in sequence, and all these keys are available twice on typical keyboards. So there is enough room left for mapping the most frequent paste-buffer functions to the keypad as described above which is considered much more useful. Use Alt-Del (or ESC Del, or Ctrl-Del) to delete the next character, or use the -k option to switch keypad key function assignments for the Home, End, and Del keys. See Keypad layout above for a motivating overview of the mined keypad assignment features and options.

Backarrow or ^H
    Delete character left. If there is only blank space before the current position in the current line and the line above, the auto-undent function (Back-Tab) is performed instead, deleting multiple spaces back to the previous level of indentation. Note: Mined tries to map this function to the Backarrow key on the keyboard whether it is assigned to the Backspace or DEL control characters, see note above.

Ctrl-Backarrow (if key properly configured) or F5 Backarrow
    "Delete single": Delete only right-most combining accent of combined character left of cursor position. If not next to a combined character: delete character left, avoiding auto-undent function.

Del (on numeric keypad)
    Cut selected area to paste buffer.

Del (on small keypad, if properly configured to be distinguished)
    Delete character right, including any combining characters.

→NEW→
    Ctrl-Del (both keypads, if key properly configured) Delete character right, excluding any combining characters.

Shift-Del (if key properly configured)
    Cut selected area to paste buffer.

HOP Backarrow
    Delete beginning of line (left of current position).

^B  Delete character right (next character).

^T  Delete next word.

^^ (overridden when used as accent prefix, e.g. with newer xterm)
    Delete previous word.

^K  Delete tail of line (from current position to line-end); if at end of line, delete line end (joining lines).

HOP ^K
    Delete whole line.

Code conversion

ESC X
    Insert hexadecimal representation of current character code. (In UTF-8 mode, this is the UTF-8 byte sequence of the character in hexadecimal notation.)

... with HOP:
    Insert character with hexadecimal code scanned from text at current position.

ESC U
    Insert (hexadecimal) Unicode value of current character (with either 4/6/8 hexadecimal digits, depending on the value); in CJK or mapped 8 bit encoding mode, the value is transformed from the current text encoding into Unicode.

... with HOP or Ctrl-Shift-F11
    Insert character with hexadecimal Unicode value scanned from text at current position; in CJK or mapped 8 bit encoding mode, the value is transformed from Unicode into the current text encoding.

ESC A
    Like ESC U but inserting an octal Unicode value.

... with HOP:
    Like HOP ESC U but scanning an octal Unicode value.

ESC D
    Like ESC U but inserting a decimal Unicode value.

... with HOP:
    Like HOP ESC U but scanning a decimal Unicode value.

Alt-x
    →NEW→ Toggle the preceding character and its hexadecimal code. The command detects a 2 to 6 hex digit character code with a valid Unicode value, or a non-digit Unicode character, respectively.

Case conversion

ESC C or F11
    Exchange case (low/capital) of character under cursor. Case mapping is based on Unicode (but applicable in all text encodings). Special handling is applied for: Greek final s, Turkish "i" if the effective locale environment variable (LC_ALL, LC_CTYPE, LANG) begins with "tr" or "az", case mappings to multiple characters, Lithuanian special conditions. Japanese characters are toggled between Hiragana and Katakana.

... with HOP or Shift-F11
    Apply case conversion to word from cursor.

Shift-F3
    Cycle casing of a word between all small, title case, and all capitals (title case means the first letter is either capital or actually a Unicode title case, the following letters are small). For Japanese script, it toggles the word between Hiragana and Katakana.

Mnemonic and special conversion

ESC _ or Ctrl-F11
    Mnemonic character substitution replaces the two characters at the cursor position with a suitable composite character (e.g. accented character) if possible. With Ctrl-F11, transformations are the same as with the ^V two-letter character input mnemonics. With ESC _, language-dependent preferences may take precedence (see variations below) according to the current locale environment.
    Example: ae->æ

  Special conversion features

    •   If the text at the cursor position contains an HTML character tag (starting with "&" and optionally ending with ";"), it is replaced with the actual character it represents.
        Example: &amp;not;->¬

    •   →NEW→ If the text at the cursor position contains an HTML numeric character entity (starting with "&#" and optionally ending with ";"), it is replaced with the respective character it denotes.
        Example: &#x40;->@
        &#64;->@

    •   →NEW→ If the text at the cursor position contains a URL numeric escape notation (starting with "%") it is replaced with the actual character it represents.
        Example: %40->@

    •   The command also transforms between Latin-1 and UTF-8 encoded characters if an accordingly encoded character is found at the current position; the current character encoding mode is used to determine the target character set.
        Example: æ (Latin-1 encoding)->æ (current UTF-8 encoding) or
        æ (UTF-8 encoding)->æ (current encoding)

As variations of ESC _, there are some commands ESC LETTER using national letters that occur on respective national keyboards. They apply basically the same transformations but with some national preferences taking precedence:

ESC ä or ESC ö or ESC ü or ESC ß
    Similar to ESC _, but with German transformation preferences.
    example: ae->ä, oe->ö

ESC é or ESC è or ESC à or ESC ù or ESC ç
    Similar to ESC _, but with French transformation preferences.
    example: oe->&#339; (oe ligature U+0153)

ESC æ or ESC å or ESC ø
    Similar to ESC _, but with Danish transformation preferences.
    example: ae->æ, oe->ø

Encoding conversion

HOP ESC ( or Alt-F11
    Search for a character encoded in the "wrong encoding", i.e. a UTF-8 character in non-UTF-8 text mode, or a Latin-1 character in UTF-8 text mode.

ESC _ or ESC ö etc.
    If invoked on a non-ASCII character, UTF-8 / →NEW→ non-UTF-8 character encoding conversion is applied: If the character is not encoded in the current text encoding it is converted into the current text encoding (from UTF-8 or from Latin-1).

Alt-Shift-F11
    Convert Latin-1 / UTF-8, then search for the next "wrong encoded" character.

Paragraph formatting

ESC j
    ("Clever Justify") Format paragraph by word-wrapping according to the currently set right margin value; left margins are derived from the contents of the paragraph and line. Heuristic detection of numbered items automatically triggers appropriate indentation.
    End-of-paragraph is a line without trailing blank space.

... with HOP:
    Same, but end-of-paragraph is considered to be a blank line.

ESC J
    ("Normal Justify") Format paragraph by word-wrapping according to the currently set left and right margin values.
    End-of-paragraph is a line without trailing blank space.

... with HOP:
    Same, but end-of-paragraph is a blank line.

ESC <
    Set left margin for justification.

ESC ;
    Set left margin of first line of paragraph only.

ESC :
    Set left margin of next lines of paragraph only.

ESC >
    Set right margin for justification.

HTML support

ESC H (every first time)
    Enter HTML tag (and remember for subsequent ESC H). (Note that Alt-Shift-H will do the same thing if your terminal is configured appropriately - see the example configuration file Xdefaults.mined in the Mined runtime support library.) The tag can be entered with attributes and values; these will not be repeated in the closing tag (see next entry on ESC H).

ESC H (every second time)
    Enter closing HTML tag. Any tag attributes and values entered with the tag (see previous entry on ESC H) will be left out.

HOP ESC H
    Put text between mark and current position in HTML tags. The "A" tag gets special treatment.

  Text block and buffer operations

Note on the Home, End, and Del keys
    Many people expect the "Home" and "End" keys to move the cursor to the beginning or end of line, respectively, and the "Del" key to delete the next character. In the keyboard usage approach of mined, this is a waste of keyboard resources as these functions can easily and quite intuitively be invoked with "HOP left" and "HOP right", i.e. by pressing the keypad keys "5 4" or "5 6" in sequence, and all these keys are available twice on typical keyboards. So there is enough room left for mapping the most frequent paste-buffer functions to the keypad as described above which is considered much more useful. Use Alt- (or Ctrl-) with the Home, End, or Del keys for the line positioning and character deletion functions, depending on terminal support and configuration; or use the -k option to switch keypad key function assignments for the Home, End, and Del keys. See Keypad layout above for a motivating overview of the mined keypad assignment features and options.

^@ (Ctrl-Space)

or Home (on right keypad) or Shift-Home

or ^] or ESC @ or ESC ^

or Stop (sun)or Select (vt100)
    Set mark (to remember the current location).

... with HOP:
    Goto mark.

^Y

or End (on right keypad) or Shift-End

or Copy (sun) or Do (vt100)
    Copy selected text (between mark and current position) to paste buffer.

... with HOP:
    Append to buffer.

^U

or Del (on right keypad) or Shift-Del

or Cut (sun) or Remove (vt100)
    Cut selected text (between mark and current position) to paste buffer.

... with HOP:
    Append to buffer.

^P or Ins or Ctrl-Ins

or Paste (sun) or InsertHere (vt100)
    Paste contents of buffer to current position.
    With ^P or Ctrl-Ins, the cursor is placed before the pasted region. With Ins, the cursor is placed behind the pasted region unless the option -V was used.
    In rxvt, with Ins on the left keypad, the cursor is placed before (left of) the pasted region.

... with HOP: (e.g. HOP Ins or ^G^P)
    Paste from inter-window buffer. Thus you can quickly copy text from one invocation of mined to another.

Alt-Ins or Ctrl-F4
    Replace text just pasted with preceding paste buffer. This command uses a ring of paste buffers (like emacs "yank ring").

^G N m or ESC g N ,
    (N=0..9) Set marker N. (^G N , also works.)

ESC m N
    (N=0..9) Set marker N.

^G N ' or ESC g N '
    (N=0..9) Go to marker N. (^G N g or ^G N . also works.)

ESC ' N (deprecated)
    (N=0..9) Go to marker N.

ESC b or Shift-F4
    Copy contents of paste buffer into a file.

... with HOP:
    Append to file.

ESC i or F4
    Insert file at current position.

Print from File menu
    Print text being edited (to default printer).

HOP ESC ! or (deprecated) ESC c
    Invoke operating system command (prompted for) with paste buffer as input.

  Search

Note on case-insensitive searching
    →NEW→ Mined applies case-insensitive search pattern matching where the search pattern contains small characters, unless when searching for an identifier (current identifier occurence, HOP F8, or identifier definition, Alt-t). For a case-sensitive search for a small letter, use a single-letter range expression like [x] or a backslash escape like \x.

ESC / or Find or F7 or F8
    Search forward (prompt for regular expression).

... with HOP:
    Search for current identifier.

ESC \ or Alt-F7 or Alt-F8
    Search backward (prompt for regular expression).

HOP F8 or Shift-F9
    Search for current identifier.

HOP Alt-F8 or Alt-Shift-F9
    Search for current identifier backward.

HOP Shift-F8 or ESC t or Alt-t
    Search for definition of current identifier (using tags file). See ESC t below for further description.

HOP Ctrl-Shift-F8
    Search for identifier definition (prompts for identifier).

HOP Ctrl-F8 or Ctrl-Shift-F9
    Search for current character.

^N or F9
    Search for next occurence (using previous search expression and direction).

... with HOP:
    Repeat last but one search; two alternating search expressions can be used with this command.

Alt-F9
    Search again (for last expression) but in the opposite direction.

ESC , or Shift-F8
    (Global) Substitute (prompt for search and replacement strings).

ESC r or Ctrl-F8
    (Global) Replace with confirmation prompting (first prompt for strings).

ESC R or Ctrl-Shift-F8
    (Line Replace) Substitute on current line (prompt for strings).

ESC ( or ESC ) or ESC { or ESC }
    Perform one of the following matching searches, depending on text: Search for corresponding bracket matching the bracket at current position in one of the pairs (), [], {}, <>, «». (Nested matching bracket pairs are skipped.) In an HTML or XML file, search for matching tag (nesting considered). Search for matching /* */ comment delimiter. Search for matching #if #else/#elif #endif structures (nesting considered). On an #else or #elif directive, the search direction depends on the command character, i.e. ESC ( searches backward, ESC ) searches forward. In a mailbox file, on any mail header line, search for next or previous mail message, depending on the command character, i.e. ESC ( searches backward, ESC ) searches forward. In a mailbox file or saved mail message, on a MIME separator, search for next or previous MIME separator, depending on the command character, i.e. ESC ( searches backward, ESC ) searches forward.

ESC t or HOP Shift-F8
    Search for and move to the location of the definition of identifier at the current cursor position. This command uses the tags file that can be generated with the ctags command (Unix). It opens another file if necessary and automatically saves the current file then.
    Like with a number of positioning commands, ESC t places the current position on the position marker stack before going to the location of the identifier definition. The command ESC Enter (Alt-Enter) can move back to that position, even if edited files were changed with the command.

HOP ESC t
    Similar, but prompts for identifier.

HOP ESC ( or Alt-F11
    Search for a character encoded in the "wrong encoding", i.e. a UTF-8 character in Latin-1 mode, or a Latin-1 character in UTF-8 mode.

  Special functions in a search string

matches any character.

^   (at begin of pattern) restricts match to the begin of a line.

$   (at end of pattern) restricts match to the end of a line.

[< character set >]
    matches any one of a set of characters; the set may be given by listing elements, denoting a range < c1 >...< c2 >, or negating the whole set [^< character set >].

\< character >
    matches the character literally.

< pattern >*
    (a star appended to any one of the defined patterns) matches a (zero or more times) repetition of this pattern. In a final position within the search expression, however, it matches one or more times this pattern.

^V^J or \n
    (a linefeed character or its representation) searches for newline embedded in the search pattern

→NEW→ \r
    searches for DOS/Windows newline (CRLF) embedded in the search pattern

  Special functions in a replacement string

&   is replaced by the matched pattern to be replaced.

^V^J or \n
    (a linefeed character) embeds a newline (LF character) in the replacement string

\r  (a carriage return character) embeds a CR character in the replacement string

  File operations

ESC w or F2
    Save (write back) current text to file (only if modified).

... with HOP:
    saves current file position in marker file @mined.mar, so that subsequent editing sessions will start at the current position and remember formatting parameters.

ESC W or Shift-F2
    Save (write back) current text to file (unconditionally).

Alt-F2
    Save As; save current text to file with different name; →NEW→ file permissions (access modes) are preserved and cloned.

Ctrl-Shift-F2 or HOP Shift-F2
    Save to file, and enable memory for file positions in current directory; current file positions will always be saved in marker file @mined.mar so that subsequent editing sessions will start at the current position and remember formatting parameters.

F3  Edit another file (prompt for save if current text changed).

Ctrl-F3 or ESC v
    View another file (prompt for save if current text changed).

ESC V
    Toggle between edit mode and view only mode.

ESC q
    Quit the editor (prompt for save if current text changed).

ESC ESC or Ctrl-F2
    Exit editing current text (save first if changed), continue with next file if multiple files are being edited, otherwise exit mined. Note: There is a small delay after typing ESC ESC. (This is in order to enable recognition of Alt-function key combinations which are implemented by some terminals or terminal modes by prefixing ESC to the function key escape sequence.) This delay can be avoided by using Ctrl-F2.

ESC +
    Edit the next file in the list of files being edited.

... with HOP:
    Edit the last file in the list.

ESC -
    Edit the previous file in the list of files being edited.

... with HOP:
    Edit the first file in the list.

ESC #
    Ask for index into the list of files and edit that file.

^G N # or ESC g N #
    Edit Nth file. (^G N f also works.)

ESC # #
    Reload file currently being edited.

  Menu

ESC Space or Alt-Space or Shift-F10
    Open Popup menu.

Alt-F10 or Ctrl-F10
    Open first flag menu (Info menu).

ESC f or Alt-f or F10
    Open File menu.

ESC < letter > or Alt-< letter >
    Open menu.

ESC I or Alt-I or ESC K or Alt-K or Ctrl-F12
    opens the Input Method selection menu (Alt-I/Alt-K/Ctrl-F12 also works on prompt line)

ESC Q or Alt-Q
    opens the Smart Quotes selection menu

ESC E or Alt-E
    opens the Encoding selection menu

  Miscellaneous

ESC = < count >
    Repeat a command < count > times (prompts for count). Example: ESC=7< cursor down > moves the cursor 7 lines down. Note: If the function to be repeated is a character to be inserted and the input is keyboard mapped to a multi-character sequence, only the first character of the sequence is inserted repeatedly.

ESC < count >
    Repeat a command < count > times (prompts for rest of count); this short form is only accepted, however, if the repeat count consists of at least two digits (this is to avoid confusion with function key escape sequences of certain terminals). Example: ESC77. enters a line of 77 dots, ESC07x enters "xxxxxxx".

^V < function key >
    Invoke function as if pressed together with the control key. E.g. ^V < cursor-left > moves left into the parts of a combined character just like Ctrl-cursor-left would do (the latter may depend on proper terminal setup).

^\  Abort current command, e.g. while on prompt line.

ESC ?
    Show the current status of the file (name, whether modified, current line, number of lines, characters, and bytes).

... with HOP:
    Toggle permanent display of text status line. Note that when editing a file that does not fit completely in memory (e.g. large file on old system), this option may cause considerable swapping. In that case, do not use the feature.

ESC u
    Display the character code of the current character in the bottom status line. (In UTF-8 encoded text mode, both the UTF-8 byte sequence and the Unicode value are displayed; in CJK or mapped 8 bit encoded text mode, Han or 8 bit character values and corresponding Unicode values are displayed when applicable.) In non-Latin-1 encoded text mode, additional Unicode information is included, indicating the script, character category, width, combining, and surrogate properties of the character.

... with HOP:
    Toggle permanent character code display.

ESC T
    Toggle Tab width. Alternates the width interpretation of Tab characters between 4 and 8.

... with HOP:
    Toggle Tab expansion (input substitution with spaces).

ESC P
    Set page length (number of lines that mined assumes to be on a page). (Useful for status display.)

ESC a
    Toggle append mode (append to text buffer/file instead of overwriting).

ESC d
    Show current directory / change to another one (also change drive in MSDOS version).
    The assumed (relative) file path name →NEW→ as well as file permissions (access modes) are preserved.

ESC n or Set Name... from File menu
    Change the file name associated with the text being edited; the file is not actually saved yet but only the new file name is used for saving the next time. The text is detached from the file previously loaded which is not affected.
    All current text editing properties (assumed encoding, smart quotes style, margins, ...) →NEW→ as well as file permissions (access modes) are preserved.

ESC .
    Redraw the screen.

ESC l
    Make screen lower (decrease number of screen lines).

ESC L
    Make screen higher (increase number of screen lines).

ESC %
    Make screen smaller (decrease screen size).

ESC &
    Make screen bigger (increase screen size).

ESC z
    Suspend editor process; first write back file if modified (no write if HOPped or given empty file name on prompting).

ESC !
    Fork off a shell and wait for it to finish.

... with HOP:
    Invoke operating system command (prompted for) with paste buffer as input.

F1 or Help or Alt-h or ESC h
    Online help function. Selection of help topics is offered and prompted; after entering the initial letter, the respective help section is shown.
    If another (modified) F1 key, a modified digit key, or a Ctrl-modified punctuation key is entered, a corresponding key assignment help bar is displayed (see F1 F1 etc. below).
    The online help file mined.hlp is installed with the Mined runtime support library. If this is not installed in one of the standard locations, the environment variable MINEDDIR should be set to point to the directory so mined can find its online help file.

... with HOP:
    If followed by a topic selection (initial letter after prompt), view online help with mined (in read-only mode) by opening the online help file (instead of invoking the "less" viewer) and positioning to the selected help topic.
    Before opening the help file, the text being edited is automatically saved (if it was modified) and any prompting required will be performed. The suspended editing session will automatically be restored after help viewing is finished.

F1 F1 or Shift-F1 or Ctrl-F1 or Alt-F1 or Ctrl-Shift-F1 or Alt-Shift-F1
    Display a help bar (in the bottom status line) with short indications of the functions assigned to the function keys F2... in the corresponding modified mode (i.e. with Control, Shift, and Alt as requested for the help bar).

... with HOP:
    Toggle permanent help bar display.

F1 Ctrl-1 or F1 Alt-1 or F1 Alt-Ctrl-1
    →NEW→ Display a help bar (in the bottom status line) with short indications of the accent prefix functions assigned to the digit keys 1..9, 0 in the corresponding modified mode (i.e. with Control and Alt as requested for the help bar).

... with HOP:
    Toggle permanent help bar display.

F1 Ctrl-< punctuation key > e.g. F1 Ctrl-,
    →NEW→ Display a help bar (in the bottom status line) with short indications of the accent prefix functions assigned to the Ctrl-modified punctuation keys.

... with HOP:
    Toggle permanent help bar display.

ESC While a command is active and prompting (e.g. for a search expression), ESC aborts the current command.

ESC Space
    Do nothing, so the Space key aborts the ESC command.

  MSDOS only

Ctrl-Alt-Space
    Set mark (to remember the current location).

F1 or ESC h
    If followed by a topic selection (initial letter after prompt), view online help with mined (like HOP F1).

Screen size change functions
    MSDOS screen size changes depend on a mode table contained in the source file keydefs.c.
    In the presence of a TSR driver which can change fonts and screen modes while running a program (e.g. the excellent VGAMAX), the actual change effective may occasionally be unexpected. Mined does however recognise those changes and adjusts its conception of screen size appropriately, although only after the next character being input.

Alt-- (on keypad)
    Change video lines mode to the mode with the next smaller number of lines but same number of columns. (The number of lines is first tried to be decreased within the current video mode. If it is already the lowest, the next video mode is chosen.)

Alt-+ (on keypad)
    Change video lines mode to the mode with the next higher number of lines but same number of columns.

Ctrl-- (on keypad)
    Change video mode to the mode with the next smaller total resolution (lines * columns).

Ctrl-+ (on keypad)
    Change video mode to the mode with the next higher total resolution.

Alt-/ (on keypad)
    Switch between highest and lowest line number modes within the current basic screen mode.

Ctrl-/ (on keypad)
    Cycle through all line number modes within the current basic screen mode.

HOP Ctrl-/Alt- +/- (on keypad)
    Several other video mode settings are prompted for (experimental).

  emacs mode
Mined emulates emacs keyboard layout and some specific functions if invoked with the option -e or with the command name alias minmacs.
In emacs mode, emacs command key assignments to control keys, ESC (Meta commands) and ^X (C-X commands) are configured. In addition, the following emacs-compatible changes apply:

    •   The mined ESC commands can be reached via M-x. (Function keys remain unaffected.)

    •   The Del key (on the small keypad) is configured to delete the previous character.

    •   The control key insertion prefix is ^Q.

    •   The quit character (e.g. for the prompt line) is ^G.

    •   The emacs multiple buffer ring is fully enabled.

    •   Paragraph justification mode is set to consider an empty line as paragraph separation by default.

    •   Mined ESC commands can be reached via M-x (Alt-X).

    •   ^\ (Ctrl-\) is interpreted as an additional HOP key.

    •   Keyboard mapping (input method) can be toggled with Alt-F12

  Terminal environment
The Unix terminal type is determined from the environment variable TERM.

Recognition of some special terminal features or restrictions is associated with the setting of TERM (xterm, linux, vt100, sun*, cygwin, rxvt, *ansi*, 9780*, hp*, xterm-hp, superbee*, sb*, microb*, scoansi*, xterm-sco, cons*, att605-pc, ti_ansi, mgterm). Non-trivial screen features (like scroll reverse, add/delete line, erase multiple characters) are used if their support is indicated in the termcap/terminfo description of the terminal unless other information is available (e.g. after terminal version detection, an older xterm is supposed not to support erase characters). Since colour support is often not configured within terminfo but modern terminals do support it, mined always tries to apply colour attributes (if the terminal at least supports ANSI control sequences). A number of other "best practice" approaches are taken to optimize the usage of terminal capabilities, esp. covering different methods of graphics display support (for menu borders).

For detection of function keys and cursor keys, the escape sequences being used by terminals are often not known to an operating system environment because they are poorly and incompletely configured. Because this does usually not work as expected (see this bug report just for an example), mined does not rely on the termcap/terminfo configuration of function key codes alone (which it considers however since mined 2000.14); rather it always accepts a wide variety of typical codes. A few ambiguous codes are resolved according to the TERM variable.

In an xterm, window headline and icon text are set to the current filename and "(*)" is added if the text has been modified.

  Locale configuration
The locale mechanism as implemented on modern systems has a number of design problems, one being that there is no explicit distinction between text encoding and terminal encoding although this is obviously a very different thing and mixed combinations of both may occur and are actually supported by mined.
For this reason, mined extends the locale environment variable mechanism with the variable TEXTLANG which is only considered for assumed text encoding (with precedence over the other locale variables). Also mined provides additional features to specify both terminal and text encodings.

    •   For text encoding, mined checks the variables TEXTLANG, LC_ALL, LC_CTYPE, LANG in this order.

    •   For terminal encoding, mined checks the variables LC_ALL, LC_CTYPE, LANG in this order.

    •   Explicit command line parameters are available to specify either terminal encoding (+E) or text encoding (-E). They override environment variable settings.

    •   UTF-8 terminal auto-detection overrides other terminal encoding settings.

    •   Text encoding auto-detection overrides environment settings but not command line settings.

    •   Assumed text encoding can be switched while editing.

For encoding recognition from locale environment variables, mined recognises locale specifications typically found in system installations, including those which do not include an explicit encoding suffix. Known character encoding suffixes ("codeset" component of locale name, starting with ".") are recognised regardless of whether the given locale is installed or not. Other encodings are recognised by region suffix (starting with "_") or full locale name or alias.
In addition to hard-coded locale recognition (especially for CJK), locale values and associated encodings are configured in the compile-time configuration file locales.cfg which especially lists locale names that do not have an explicit encoding suffix. You can use these settings (known locale name or generic locale name suffix) even on legacy systems without locale support to indicate the terminal environment properly to mined. For encoding recognition from command-line parameters, mined provides three options:

    •   -EX or +EX with a single-letter encoding tag as listed with the description of the -E options; further encoding tags are configured in the compile-time configuration file charmaps.cfg.

    •   -E=charmap or +E=charmap with a character encoding name (as reported by the locale charmap command).

    •   -E.suffix or +E.suffix with a character encoding suffix ("codeset" of locale name).

    •   -E:flag or +E:flag with a 2-letter indication used by mined to indicate the respective text encoding in the Encoding flag.

    In each of these options, -E specifies
        text encoding while +E would specify terminal encoding to be assumed.

The following table lists major encodings and generic locale suffix values by which they are recognised; in addition (as mentioned above), a large number of locale names without encoding suffix as found on various systems in known to mined and will cause it to assume the corresponding terminal encoding.

Examples: To indicate that mined is running in a UTF-8 terminal (normally auto-detected, included here for demonstration) and should assume GB18030 text encoding by default, invoke either of:

LC_ALL=whatever.UTF-8 TEXTLANG=zh_CN.gbk mined

LC_CTYPE=whatever.UTF-8 TEXTLANG=chinese mined

LANG=whatever.UTF-8 mined -EG

LC_ALL=en_IN mined -E.gbk

mined +EU -E.EUC-CN

mined +EU -E=GB18030

mined +EU -E:GB

Selecting UTF-16 text mode: To tell mined to interpret a file (or make a new file) in UTF-16 encoding, use the following command line options (first two little endian, then big endian):

mined -E:61

mined -E=UTF-16LE

mined -E:16

mined -E=UTF-16BE

mined -E=UTF-16

Selecting ASCII terminal mode: To tell mined to assume that a terminal cannot display anything but ASCII characters, use the command line option +E:AS. Mined implicitly assumes this setting if the environment variable TERM indicates a VT52 terminal.

  PC terminals
Character encoding of PC terminals is an even greater mess than on Unix systems. Mined provides heuristic best-guess assumptions about terminal encoding, supporting both local invocation as well as remote login from a PC (e.g. to a Unix machine).

The following assumptions are made based on environment variables or command-line parameters:

encoding ("codepage")
    environment
    option

•   Windows console mode telnet (even if called from cygwin console, sets TERM=ansi)

CP437 (IBM PC VGA encoding)
    TERM=nansi*, ansi.*, opennt*, *-emx* or LC_*/LANG indicates ".CP437"

•   cygwin 1.7.0-45 console or cygwin 1.7.0-46 application configured for respective codepage

Note: It is not unlikely that the assumption about the terminal encoding taken by mined does not match the actual terminal encoding (e.g. mined cannot determine the encoding based on the ambiguous setting TERM=ansi). Environment variables that indicate the character encoding are unfortunately not maintained through telnet or remote login.
Explicitly setting TERM to a suitable value after remote login or explicitly setting the locale variables, e.g. LC_CTYPE, may help but may not always work either (e.g. pcansi is not a known terminal on SunOS; some systems like SunOS are dogmatic about interpreting locale variables which strictly need to be installed before; not all encodings, esp. PC "codepages", are known as a "locale charmap" on other systems).
In these cases, you can use the explicit +E option to force mined to assume a specific terminal encoding; see the option values listed above for the main DOS encodings.

Note: The encoding emulated by cygwin (as configured, by default Windows Latin codepage CP1252) is not the encoding natively applied by the Windows console window (by default DOS codepage CP850). This means that the effective encoding may be different if you invoke the cygwin-compiled mined version and the djgpp-compiled mined version alternatingly; you may notice this by a different range of characters that can be displayed when opening the same file with the two mined versions.
Some Windows Latin characters are poorly displayed by the Windows console in default configuration; mined 2000.13 introduced a workaround to indicate those character by a more suitable substitution instead. →NEW→ This workaround is withdrawn to support cygwin 1.7 which can display all characters properly if the Windows console font is configured to "Lucida Console" rather than "Raster Fonts".

Note: →NEW→ The following DOS codepages are supported; they are mainly provided as terminal codepages, they do not appear in the Encoding menu. However, if you need, you can ask mined to use them as either the assumed terminal encoding (e.g. +E=CP1250 or +E:WE) or even text encoding (e.g. -E=CP1250 or -E:WE) using the names or shortcuts from the list:

Note: →NEW→ Mined (djgpp) tries to determine the DOS/Windows codepage using the DOS API; this can only work if the codepage was properly configured with DOS means (e.g. with CP858 using CHCP 858 or MODE CON CP SELECT=858, maybe enabled by DEVICE=...\DISPLAY.SYS CON=(EGA,858) on old DOS); if only the font is switched to a differently encoded one, there is no way to detect this.
Sub-Note: This feature has not yet been tested. If detection does not work, you can still use environment setting or the +E option as mentioned above to indicate the terminal encoding.

Note: Running mined in a dosemu session (DOS emulator on Linux) works fine, even in an xterm-embedded session although not perfectly in that case: ^S and ^Q are interpreted for flow control (thus ^S will hold all output until ^Q is entered), and the mined option -Qa should be used to tune menu borders right.

  Terminal setup
The Mined runtime support library includes a configuration file Xdefaults.mined which lists settings that should be applied to the terminal for proper operation of several features as described throughout this manual.

In some terminals, the cursor may not be well visible or not visible at all if the cursor is on a character with reverse background (control character, occurs e.g. in xterm) or highlighted background (invalid character code, occurs e.g. in xterm and rxvt). See the X resource parameters for "cursorColor" in the example configuration file Xdefaults.mined for remedy.

If your terminal scrolls down one line when you click the left mouse button in the text area, the terminal type is not properly set up. This occurs, e.g., when you run inside a cygwin or rxvt terminal but the environment variable TERM is incorrectly set to xterm. Set it to the correct value for remedy.

If mouse wheel movement moves more than expected, especially if it cannot move by single items in a menu, this is probably a configuration issue with your mouse driver. You are probably running a Windows-based X server which is (often by default) configured to generate multiple mouse wheel events on each actual mouse wheel movement. Often not even in the Control Panel mouse section, but only in a configuration menu of mouse-specific setup software (e.g. "Browser Mouse Settings"), configure the scroll unit to 1.

  Terminal interworking problems
With some terminals, problems are known due to missing terminal features or terminal bugs:

any terminal: menu border display

•   If the borders of mined menus appear as letters rather than graphic borders, the terminal can unexpectedly not handle VT100 block graphics. Use the option -Qa to switch to ASCII borders, or -fff to limit font assumptions.
    In a UTF-8 terminal, mined uses Unicode Box Drawing characters by default. If they don't display they are missing in the font used by the terminal. Use the option -Qv to switch to VT100 block graphics or -Qa to switch to ASCII graphics. If borders are visible but without corners, use -Qs to switch to rectangular borders.

any terminal: slow terminal feature auto-detection

•   Occasionally, when starting mined, you may receive a message "Late screen mode response - set ESCDELAY=2000 or higher for proper detection".
    This happens if there is a large delay (> 700 ms) in the interaction mined uses to detect terminal properties. There are two possible reasons for this:

    •   A slow remote terminal connection. In this case, set up your environment variable ESCDELAY to a value (in milliseconds) large enough to cover the anticipated delay, e.g.: export ESCDELAY; ESCDELAY=3000

    •   Font loading. Especially with rxvt and mlterm, X fonts seem to be loaded partially on demand. While this speeds up initial terminal operation, it also results in unexpected delays of terminal responses. In this case, exiting mined and starting again will normally resolve the issue for one session of the terminal. For a more permanent remedy, also use the environment variable ESCDELAY when using those terminals, e.g.: export ESCDELAY; ESCDELAY=1200
Automatic handling of the situation is planned for the next release of mined.

mlterm

•   Bidirectional display handling of mlterm is based on the final display, not regarding any context (such as positioning control, that's why mined implements a workaround for menu display on mlterm). This also affects mouse cursor position reports which do not match over right-to-left text, so the cursor will be placed somewhere else in the line.

•   The Mined runtime support library includes a configuration file mlterm/key which defines enhanced escape sequences for function keys and other modified keys in order to enable the functionality described in this manual.

xterm

•   Although it is a waste of keyboard resources to have two indistinguishable sets of keypad keys, most terminals provide no means of distinguish them towards the applications, at least not by default. Especially for a text editor, it is highly desirable to distinguish them in order to have a rich intuitive function key mapping at disposition which mined tries to achieve.
    Remapping keypad keys in a useful way is sensitive because it may create incompatibilities with other programs that rely strictly on installed terminfo information. Mined provides remapping recommendations for shifted keypad keys (with Shift, Control, Alt and combinations of them) in the configuration sample file Xdefaults.mined in the Mined runtime support library.
    Due to the compatibility limitations mentioned above, however, the two Ins keys remain indistinguishable, and the two Del keys are only distinguishable if the xterm configuration resource *VT100*deleteIsDEL is set. Also, keypad and function key modification with the Alt is ensured with the xterm resource *VT100*metaSendsEscape. Both resources are set to true in the configuration sample file just mentioned.
    These two resources can also be set dynamically with xterm. Mined can be told to do so with the command line option +D. (Unfortunately this handling cannot be enabled by default as it cannot be undone because the previous state cannot be detected.)

•   Mined determines the xterm version in order to apply certain workarounds conditionally.

•   If you run xterm in VT220 keyboard mode (using xterm option -kt vt220 or setting the configuration resource *keyboardType: vt220) you should make sure to also set the environment variable TERM=vt220 (e.g. using the xterm option -tn vt220 or setting the configuration resource *termName: vt220) so mined can properly set up the keypad functions.

xterm on cygwin

•   On cygwin, as on other systems, the script uterm is recommended to invoke an xterm that is properly configured to run UTF-8, and also to use a best choice of fonts for optimal Unicode coverage. See README.cygwin for more detailed advice.

xterm legacy CJK width mode

•   Mined auto-detects and supports xterm legacy CJK width compatibility mode (xterm -cjk_width); character width and menu border layout are properly adjusted, stylish menu borders (-QQ) and fine-grained scroll bar display are disabled by default. (Note: In this mode, combining characters could unexpectedly change the width of a character by being substituted with its wide precomposed form (e.g. 'a' combined with U+0300) - which an application can hardly handle; this bug was fixed in xterm 224 with a patch contributed by the mined author.)

rxvt

•   When starting mined in a fresh rxvt terminal, and maybe even after starting your X server, some display (font?) initialization may take extremely long, resulting in an error message. Restart mined to ensure proper terminal properties auto-detection.

•   Rxvt does not distinguish between Shift-F1 and F11 / Shift-F2 and F12 / Ctrl-Shift-F1 and Ctrl-F11 / Ctrl-Shift-F2 and Ctrl-F12, so that the F1 and F2 keys modified with Shift cannot be recognised in rxvt by default. →NEW→ They can however be enabled with the keysym definitions in the file Xdefaults.mined in the Mined runtime support library.

•   In rxvt, the two keypad Del keys (small keypad, numeric keypad) are automatically distinguished from each other and invoke the Delete character (small keypad) and Cut (numeric keypad) functions, respectively (Ctrl-/Shift-/Alt- alternatives are supported as described in this manual). This works, however, only if mined can recognise rxvt; it is generally a bad idea to set TERM=xterm in rxvt, see also hint below.

•   Also in rxvt, the two keypad Ins keys (small keypad left, numeric keypad right) are distinguished. The left Ins key positions the cursor left of the pasted region, the right Ins key positions it right.

•   By setting rxvt in the mode that enables distinction between the two keypads, it can unfortunately not distinguish the right keypad modified with Ctrl- anymore, so Ctrl-Home/End/Del cannot work as desired.

•   Ctrl-modified punctuation keys can be enabled by following the configuration samples of the file Xdefaults.mined in the Mined runtime support library.
    Note: Ctrl-modified and shifted punctuation keys interfere with ISO 14755 input mode of rxvt; if the following key is entered twice, that mode is aborted and the modified punctuation key becomes effective as an accent prefix in mined.

•   The recent rxvt-unicode release provides a CJK terminal emulation. CJK display is buggy for characters that rxvt thinks cannot be displayed, especially for GB18030 (LC_CTYPE=zh_CN.gb18030 rxvt) but also e.g. for JIS (LC_CTYPE=ja_JP.eucjp rxvt); single bytes are then interpreted instead which amounts to an unpredictable screen width and cannot be correctly handled. (This applies mainly to character codes that are not mapped to Unicode but also to many that are mapped.)
    Moreover, CJK width handling is inconsistent for many characters in rxvt CJK mode (rxvt claims to adhere to the locale mechanism in this respect but that's not the case here - character widths are inconsistent with the locale, too).
    Remedy: Don't use rxvt in CJK-encoded mode; mined CJK terminal support is tailored to native CJK terminals (such as cxterm, kterm, hanterm) where it works fine - if you use a UTF-8-capable terminal, use it in UTF-8 mode! Mined can edit CJK-encoded files well in a UTF-8-encoded terminal.

•   In rxvt, Unicode characters that are Not Assigned are always displayed as a single-width replacement character. This is not consistent with xterm behaviour which would display them as a double-width replacement if they are located within a double-width Unicode range (which sounds reasonable). This would cause display positioning inconsistencies. Mined has a workaround for some of these cases (assuming that rxvt runs the most recent Unicode width data version available; or actually the same as mined assumes - handling of multiple auto-detected terminal Unicode versions does not cover this special case).

•   If the X windows servers has duplicate fonts installed under a common name (e.g. if it comes with a 10x20 non-Unicode font and you install a 10x20 Unicode font in addition), rxvt seems to use the wrong (i.e., non-Unicode) version of the font and does not find special characters like the default marker used in the flags menus (this was observed since rxvt 7.5, rxvt 5.8 was finding the proper font). Use the mined option -F to adapt mined to limited font usage, or fix the X server installation. Or use the script uterm to start rxvt-unicode. To start rxvt-unicode from an xterm, use uterm -rx.

•   Due to the scrollbar display workaround for hanterm (see above), the scrollbar position may be shown as blank space instead of coloured (only in rxvt CJK mode with Korean encoding and if you explicitly set TERM=xterm which you shouldn't anyway in rxvt). In this case, coloured scrollbar foreground can be enabled with the environment variable MINEDSCROLLFG="44;36" or MINEDSCROLLFG="38;5;45".

•   As a workaround for an xterm bug on cygwin, mined applies terminal size re-adjustment. This may confuse rxvt (being resized to an unexpectedly large window) if it pretends to be xterm.
    Remedy: in rxvt, make sure that the environment variable TERM=rxvt (or rxvt-unicode); the according X resource (Rxvt.termName: rxvt) is also listed in the file Xdefaults.mined in the Mined runtime support library.

•   Mined determines the rxvt version in order to use certain features conditionally.

•   CJK-mode rxvt: rxvt has some character width bugs when running in CJK encoding; e.g. when running rxvt in Big5 terminal encoding (locale zh_TW), U+FA18 is displayed with wrong screen width while in older version U+FFED was display with wrong screen width; when running rxvt in Shift-JIS terminal encoding, a number of character width bugs occur. Mined does not implement workarounds for those; in general UTF-8 terminal encoding is advisable to be on the safe side.

urxvt

•   This is rxvt-unicode as packaged for cygwin. Invoke it with a proper locale environment variable set to enable UTF-8. See also README.cygwin for more detailed hints.

cxterm

•   EUC-JP half-width characters (8EA1-8EDF) are not properly displayed by cxterm in EUC-JP mode (cxterm -JIS, not available in "classic" cxterm).

•   Due to the scrollbar display workaround for hanterm (see above), the scrollbar position may be shown as blank space instead of coloured (only in Korean encoding mode which is probably rarely used with cxterm anyway). In this case, coloured scrollbar foreground can be enabled with the environment variable MINEDSCROLLFG="44;36" or MINEDSCROLLFG="38;5;45".

kterm

•   Auto-detection of kterm as a CJK terminal works if the environment variable TERM indicates "kterm"; otherwise mined has to be told that it runs in a CJK terminal and which encoding to use:
    For kterm -km sjis, set LC_CTYPE=ja_JP.sjis (or invoke mined +ES).
    For kterm -km euc, set LC_CTYPE=ja_JP.eucjp (or invoke mined +EJ).

•   Note: By default (i.e., without explicit -km option or corresponding *vt100.kanjiMode resource configured), kterm runs in ISO 2022 mode (yes, it does indeed) which is not supported by mined.

hanterm

•   CJK display is buggy at the line beginning or after a Tab, often only the second byte of the character code is displayed as an ASCII character instead of displaying the complete CJK character.

•   Character attributes in hanterm used to be all mapped to reverse, so there was a workaround to enable a visible position in the scrollbar which is displayed as blank space. The criteria for this workaround to apply are: CJK terminal (detected or configured), TERM=xterm, Korean encoding (UHC or Johab) configured with parameter or locale. Replaced to enable nicer colours in scrollbar. To reactive workaround for older hanterm, set environment variable MINEDSCROLLFG="0".

konsole

•   Due to the lack of decent Unicode font support in the default configuration of the KDE konsole terminal, menu appearance options -QQ and -Qr should not be used; rounded borders are disabled by default.

•   The Mined runtime support library includes a configuration file konsole/xterm-modified.keytab which defines enhanced escape sequences for function keys and other modified keys in order to enable the functionality described in this manual. Unfortunately, the qt framework used by konsole inhibits the use of some keys and many key combinations.

•   It is especially irritating that konsole disregards the middle keypad key ("5" in application mode) completely; so the mined HOP function has to be invoked by alternative means.
    As a remedy, the HOP function is assigned to the "Menu" key (next to the "Windows" key on PC keyboards) in the configuration sample file mentioned above →NEW→ and is also assigned to the Menu key by default.
    An additional remedy could reassign the middle keypad key to the X key symbol Menu (using xmodmap); →NEW→ invoke the script kp5 in the Mined runtime support library for this purpose.

gnome-terminal

•   The gnome-terminal captures a number of Alt-letter key combinations for its own menu access (which can however also be controlled with the mouse). To disable this unpleasant capturing, so e.g. mined can open its own menus with Alt-letter, configure as follows:
    Open menu "Edit" - "Keyboard Shortcuts..." and check "Disable all menu access keys". Even then, however, F1 and Ctrl-F1 are suppressed by this quirky terminal.

•   This terminal does not supported modified keys (e.g. shifted keypad keys).

•   Mined implicitly assumes its -f option (for limited font usage with respect to graphic characters) when detecting gnome-terminal.

Linux console

•   Shifted function key codes are "shifted" by 2 as compared to other terminals' function key codes. →NEW→ Mined detects F11, F12, Shift-F1...Shift-F8 properly, further modified function keys are apparently not supported in the Linux console.

Cygwin console

•   The cygwin console terminal emulation does not support Shift-F1, Shift-F2 (which cannot be distinguished from F11, F12), Shift-F11, Shift-F12, nor any Control or Alt modified function keys.

•   →NEW→ Mined detects UTF-8 mode of cygwin 1.7 console (by LC_*/LANG setting or for cygwin 1.7 beta by CYGWIN containing "codepage:utf8").
    Note: After rlogin from this console, UTF-8 indication has to be ensured explicitly, e.g. by environment setting, or by mined option +U.

•   Note: Cygwin console in UTF-8 mode provides extended Unicode font support if you select "Lucida Console" TrueType font from its Properties menu.

•   See also README.cygwin for more detailed hints on weird details about the Windows console in different modes.

Windows console window (DOS command prompt)

•   The Windows console window is normally configured to run in CP850 encoding; depending on Windows version or font, however, it may also turn out to use CP437 instead. In this case, some characters are replaced by graphic symbols, e.g. the sputnik symbol "¤" used by mined as a replacement character for non-displayable Unicode characters. This happens, e.g., with the 10 x 20 raster font. As a workaround, use a different font, e.g. 10 x 18 or Lucida Console.

•   With the djgpp-compiled version apparently there is a Ctrl-C problem on older Windows versions. Every first Ctrl-C will display ^C on the screen at the current position without mined noticing it, while every second Ctrl-C will be passed to mined. This problem does not occur on Windows XP. It does occur on Windows ME in a Windows console window. It does not occur with the cygwin-compiled version.

Poderosa

•   This Windows terminal emulator can be used for UTF-8 editing. To ensure proper function, do not use Terminal Type "kterm" or Encoding "euc-jp" or "shift-jis"

•   Mined auto-detection and terminal initialization can cause Poderosa to display warning popups. To avoid them, Select Tools - Options... - Terminal; for "Behavior in case of unexpected chars", disable "Display a message box". If you get a notice "Failed to decode characters by the current encoding utf-8.", click "Do not display this message from next time".

PuTTY

•   This Windows terminal emulation for remote login provides various keyboard (esp. keypad and function key) assignment emulations. In SCO mode, shifted function keys are different from those of xterm SCO function key emulation; both are supported.

luit

•   The locale support add-on for text terminals luit which applies encoding transformations (e.g. with LC_ALL=zh_CN.gb18030) often maps characters incorrectly, including using the wrong cell width.

  Work-around support to enable 8-bit character set on weird terminals
There exist some exceptionally weird 7 bit terminals that have an alternative character set containing composed characters which can be displayed simultaneously with the default character set. For those there is optional output translation which embeds non-ASCII characters into the respective code switching sequences. To enable output character transformation, set the environment variable MINEDOUT to contain the upper half (with respect to an 8 bit character set) of the translation table into the terminal's alternate character set. (Character set switching will be done as specified in the termcap (as/ae) or terminfo (smacs/rmacs) entry.) An example setting of MINEDOUT is included in the environment sample file profile.mined in the Mined runtime support library for Siemens 9780x terminals.

  Concerning some especially stupid terminal drivers
There used to be terminal drivers which make use of the soft handshake mechanism by exchange of ^S and ^Q characters but yet pass them through to application programs which is quite stupid. If it is necessary to ignore such hazardous ^S and ^Q keys, the environment variable NoCtrlSQ or NoControlSQ must be set. Mined will then not disable the tty channel soft handshake setting either.

  Keyboard mapping / Input method pre-selection
With the environment variable MINEDKEYMAP the active or standby mapping or both can be preselected. The value is a two-letter script tag to set the active mapping, or it is prepended with "-" to set the standby mapping, or a combination.
Example: export MINEDKEYMAP=-gr will set Greek keyboard mapping standby. export MINEDKEYMAP=py-rs will set Pinyin input method active and Radical/Stroke input method standby.
The respective tags attached to the keyboard mappings can be looked up in the Input Method flag menu; the HOP function toggles between display of the full input method name and its tag.

  Smart Quotes style configuration
Smart quotes style can also be preselected with the environment variable MINEDQUOTES which should then contain the opening/closing quote pair or just the opening quote mark (double or single quotes).
Example: export MINEDQUOTES="»" sets these »Danish« quotes and corresponding single smart quotes. export MINEDQUOTES="»»" sets these »Finnish» quotes and corresponding single smart quotes.
The value of the MINEDQUOTES variable must be encoded in UTF-8.

  Han info configuration
With the environment variable MINEDHANINFO, the information shown for Han characters can be preselected. If the variable is defined, Han info mode is enabled. It may contain letters to select description, pronunciation information, and display mode to be used:

M   show Mandarin pronunciation

C   show Cantonese pronunciation

J   show Japanese pronunciation

S   show Sino-Japanese pronunciation

H   show Hangul pronunciation

K   show Korean pronunciation

V   show Vietnamese pronunciation

P   show Hanyu Pinlu pronunciation

X   →NEW→ show XHC Hanyu Pinyin pronunciation

T   show Tang pronunciation

D   show character description

F   display full information (in popup-menu form); without F, the information will be shown on the status line where it is subject to truncation

  Common paste buffer configuration
The paste buffers, used for cut/copy/paste operations, as well as the inter-window paste buffer, are located in a temporary directory, using system conventions by default. To maintain the inter-window paste functionality even remotely, mined uses the environement variables MINEDTMP and MINEDUSER which, in combination, point to a user-defined temporary directory and file name pattern to be used for buffer files:

    •   Set MINEDTMP to refer to a common mounted network directory on all machines which means that the value of $MINEDTMP may have to be different to reflect different mount points across the network.

    •   Set MINEDUSER to the same name within the network even if using different user name accounts.
For details, see also the FILES section below.

  Keypad configuration
Some X configuration may have to be applied to enable keyboard input features as used by mined:

    •   Alt key modifier for quicker entry of "ESC" commands.

    •   Assignment of the HOP function to the middle keypad key ("5").

    •   Assignment of the HOP function to other keys (especially for convenience on laptops which do not have the numeric keypad), e.g. the Pause or Scroll Lock key.

    •   Distinguish "Home" and "End" keys of the two keypads in order to make use of this redundancy of typical keyboard layout (which is actually a waste of physical resources, causing unnecessary wrist strain because it increase the distance to be moved over for reaching to the mouse).

    •   Enable control and shift modifiers for keypad and function keys.

    •   Enable control and shift modifiers for digit keys (for use as accent prefix).

    •   Enable control modifier for punctuation keys (for use as accent prefix).
See the example file Xdefaults.mined in the Mined runtime support library for suggestions.

  Printing configuration
Mined uses the script uprint from the Mined runtime support library to print the current contents of the text being edited in any selected encoding (unless the environment variable MINEDPRINT is set to direct mined to use a different print command).
If the support library is not installed in one of its standard locations (system-dependent), it should be made available in the usual command search path. The script uses either paps or uniprint for actual formatting (print preprocessing). →NEW→ Under Windows, if neither paps nor uniprint happens to be installed, uprint uses notepad /p for printing. The djgpp-compiled version uses notepad directly.
paps is available at http://paps.sourceforge.net/ and uses the Pango layout engine for formatting. uniprint is part of the yudit distribution; if you don't have it installed on your system, there is another script makeprint in the support library which can be used to download and build the needed uniprint program. The mined print script (uprint) prefers paps if it is available as it has more capabilities for printing a wide range of Unicode characters, and it does right-to-left formatting.
The font to be used with uprint can be configured with the environment variables FONT, FONTPATH, FONTSIZE. Also the printer can be configured as usual with PRINTER. In addition, uprint checks an environment variable LPR for an alternative for the system printing command (lpr/lp) if that is needed.
Note: If printing with uprint fails for some reason, mined tries to print with either the print command configured in the environment variable LPR as a fallback, or with lp/lpr as a last resort. Working character encoding support cannot be expected in this case, however.
See Environment variables to configure Printing for further details.

  Display layout
Some of the special indication characters (that substitute non-displayable contents) and some of the colours used by mined for special indications and interactive elements may be configured to the user's preference.
Note: For the configurable character indications, two environment variables exist each, to configure an 8 bit value (Latin-1 encoded) and to configure a Unicode value (UTF-8 encoded). The UTF-8 encoded values (e.g. MINEDUTFRET) take precedence in a UTF-8 terminal. In an 8 bit terminal, or if the respective UTF-8 variable is not configured, the Latin-1 encoded value applies. See the example script profile.mined in the Mined runtime support library for more details and for a number of suggestions of suitable values. Mined does not apply any default non-Latin-1 indications in order to avoid display problems with fonts that do not support them. Depending on your visual preference, there are a number of suitable Unicode characters for use as indications especially in the Unicode ranges of Arrows, Geometric Shapes and Symbols (U+2190-U+2BFF).
Note: For the Latin-1 encoded configured indication markers (variables MINEDRET etc, not MINEDUTFRET etc), if the configured character is in the small letters range (actually
 '`'...DEL) the alternate character set is used for display. This works also in a UTF-8 terminal, provided that the corresponding UTF-8-encoded indication configuration variable is not set, e.g. MINEDRET=j MINEDUTFRET= (or not defined) would indicate line-ends by displaying a graphic lower right corner, MINEDTAB=\` MINEDUTFTAB= (or not defined) would indicate Tab characters with vt100 block graphics lozenge rhombs.
Note: For the UTF-8-encoded configured indication markers (variables MINEDUTFRET etc), if the marker is a double-width character, a replacement will be displayed instead.
Note: Mined reduces its assumptions about available graphic and special characters for display purposes with the options -f or -F. The -F option also suppresses the interpretation of the MINEDUTF* environment variables.

  Line ends
Line ends are usually marked by a "«" double left angle character. This visual indication can be changed with the environment variable MINEDRET (8 bit terminals) or MINEDUTFRET (UTF-8 terminals). The default or configured marker is used as an indicator at the end of every text line on screen (so you can see how many blank spaces there are).
Multi-character markers: If a second character is configured, it is used to fill the rest of the screen line, a third configured character would terminate the indication at the end of the screen line. ("··«" is a nice setting for people who used to work at Siemens terminals.) Pattern:
MINEDRET=123    # line end displays as 122222223
Suggestion for a nice line end on UTF-8 mode terminals (check if character is included in your font, however!):
MINEDUTFRET=&#9166;    # U+23CE

The indication of DOS line ends (CRLF) and Mac line ends (CR) may be configured with the variables MINEDDOSRET or MINEDUTFDOSRET, and MINEDMACRET or MINEDUTFMACRET, respectively. →NEW→ They are also distinguished by different colours.

With the option -p, mined displays distinct indicators for line ends and paragraph ends. A paragraph is defined to continue while lines end with white space (space or Tab character). The default paragraph marker is "¶" and is also used to indicate a line ending with a Unicode Paragraph Separator. It can be changed with the environment variable MINEDPARA or MINEDUTFPARA.

  Tab characters
Tab characters are usually indicated by a sequence of '·' (middle dot) characters. This can be changed with the environment variable MINEDTAB (8 bit terminal) or MINEDUTFTAB (UTF-8 terminals).
Multi-character markers: If two characters are configured, the second is used to mark the middle of the Tab span. If three characters are configured, the first and last are used to mark the beginning and end of the Tab span. Pattern:
MINEDTAB=123    # Tab displays as 12222223
MINEDTAB=12    # Tab displays as 11112111

  Long lines
Lines which are too long for the screen are usually indicated by a '»' double right angle (guillemot) character. If the current position is behind the screen margin, the line is shifted out left which is indicated by a '«' double left angle. These markers can be changed with the environment variable MINEDSHIFT or MINEDUTFSHIFT. The first character is used to indicate a line continued to the left of the screen, the second character is used to indicate a line continued to the right of the screen.

  Unicode characters
For a description of special display indications in UTF-8 text editing mode see "Unicode display" above. The indication and highlighting mode of a non-displayable Unicode character (typically a UTF-8 character in a Latin-1 terminal), as well as the highlighting mode (colour) of the indication of illegal UTF-8 sequences, can be configured with the variable MINEDUNI.

  Display mode of indicators
It is recommended to display these indicator characters in a dim display mode to prevent distraction from the text contents. The default is a red colour which is a moderate dark red in xterm. The display mode can be used by placing the code part of an ANSI display control sequence in the environment variable MINEDDIM. E.g., MINEDDIM=31 would select the default mode, red foreground; in xterm only, MINEDDIM="38;5;83;38;5;245" gives a moderate gray in either 88 or 256 color mode; in rxvt only, MINEDDIM="38;5;83" gives a moderate gray.
→NEW→ MINEDDIM can also be set to an empty value to have mined apply dim colour to the indications; the colour value is computed from the current foreground and background colours (works in xterm). The ANSI colour 7 (white) is temporarily redefined for this purpose and restored when mined exits.

  Display mode of menu borders
→NEW→ The display colour of menu borders and menu headers can be configured with the environment variable MINEDBORDER. Suitable values are "35" (magenta), "34" (blue) and "31" (default).

  Status line highlighting
Highlighted parts of status line messages (e.g. initial letters for help selection after F1) can be configured with the environment variable MINEDEMPH, using foreground ANSI modes. The default is "31" (effectively red background).

  Scrollbar colour
The foreground and background colours of the scrollbar can be configured with MINEDSCROLLFG and MINEDSCROLLBG, respectively, using ANSI modes; if only the background is configured, the foreground is the reverse of it. In general, to support fine-grained scrollbar display in UTF-8 terminals, the foreground and background colour settings should be the reverse of each other. The default for the background is "46;34;48;5;45" if use of 256 colour mode is enabled, or "46;34" if it is disabled. The default for the foreground is "", meaning that the reverse background is used, with a workaround for hanterm (see above).

  Menu colour and border style
The highlighting background colour of the selected menu item can be configured with MINEDSEL, using reverse ANSI modes (i.e. using foreground parameters for the background) and MINEDSELFG for the foreground, using reverse ANSI modes. The default values are MINEDSELFG="43" and MINEDSEL="34", giving yellow on blue. If selected menu items appear too dark (which mined tries to avoid, depending on the terminal), try one of the workarounds MINEDSEL="34;1" or MINEDSELFG="43;1".
Menu border styles can be selected with the option -Q. For a nice selection bar that extends from left to right menu border, the setting -QQ is recommended (this is the default unless the terminal is assumed not to provide sufficient font configuration for this option; it depends on certain graphic Unicode characters being included in the terminal font and can be disabled with -Qq).

  Combining character display
The highlighting background colour of combining characters displayed in separated mode can be configured with MINEDCOMBINING, using ANSI background modes. The default value is MINEDCOMBINING=46, to change colour e.g. to yellow background, use MINEDCOMBINING=43.

  Online Help access
Mined looks for its online help file in a number of typical directories for installation of the Mined runtime support library. If it is placed in a non-standard location, the environment variable MINEDDIR should point to the directory. (Mined also tries to find the online help file in the directory where it was started from; this is especially useful for the DOS/Windows version.)

  Mined configuration

  Script highlighting
The the mined distribution contains a file src/colours.cfg; it contains entries with the script name (as listed in the Unicode data file Scripts.txt), blank space, and a colour index into the xterm 256-colour mode. (To make good use of 256 colour mode, the terminal program should be compiled with 256 colour support enabled. Configure xterm with configure --enable-256-color .)
Edit colours.cfg before building mined to adapt coloured script display to your preferences.

  Encodings and Encoding menu
The mined distribution contains a file src/charmaps.cfg which defines the character encodings that mined knows and how they are presented in the Encoding menu, together with flags for indication in the Encoding flag and tags for use with the -E and +E options (and the MINEDDETECT environment variable).
The configuration file allows the definition of sub-menus in the Encoding menu.
Each character encoding entry charmap-name must correspond to an existing character mapping file charmaps/charmap-name.map. Additional character mappings can be generated with the script mkchrmap.

  Encodings recognised by locale names
The mined distribution contains a file src/locales.cfg which maps locale names to associated character encodings. While this list contains mainly locale names without explicit encoding suffix, mined also checks generic locale name suffix values and assumes the corresponding terminal encoding. Thus the given names or suffixes can be used even on legacy systems without locale support to indicate the terminal environment and preferred text encoding properly to mined.

  Keyboard mapping (Input method)
The mined distribution contains a file src/keymaps.cfg and a script mkkbmap; go into the src directory and use the script to generate additional keyboard mappings: The parameter to the mkkbmap script can be one of

    path.../name.mim
        a keyboard mapping file of the m17n-db multilingualization package

    path.../name.kmap
        a keyboard mapping file of the yudit text editor

    path.../name.vim
        a keyboard mapping file of the vim text editor

    path.../name.cit
        an input method mapping file of the cxterm terminal, binary form; only works if the cxterm binary/text conversion utility cit2tit is accessible

    path.../name.tit
        an input method mapping file of the cxterm terminal, text form; only works if the character set conversion utility iconv is accessible and works on the mapping file

    path.../name.utf
        an input method mapping file of the cxterm terminal, already converted to UTF-8 encoding (e.g. with iconv)

    Cangjie [ < HKSCS Changjie table file name > ]
        with this tag, a keyboard mapping for the Cangjie input method will be generated, taking information from the Unihan database (unicode.org);
        with a second parameter, a Big5-encoded table of HKSCS Changjie input codes will be merged in, the parameter is either the file name or a + sign which is implicitly expanded to the relative path name etc/charmaps/hkscs/hkscs-2004-cj.txt; the HKSCS input codes file should be taken from http://info.gov.hk/digital21/eng/hkscs/

    MainlandTelegraph , TaiwanTelegraph
        with one of these tags, a keyboard mapping will be generated using one of these telegraph codes as an input method, taking information from the Unihan database (unicode.org)

    Cantonese , HanyuPinlu , Mandarin , Tang
        with one of these tags, a keyboard mapping will be generated using the according Chinese pronunciation as an input method, taking information from the Unihan database (unicode.org)

    JapaneseKun , JapaneseOn
        with one of these tags, a keyboard mapping will be generated using Japanese or Sino-Japanese pronunciation as an input method, taking information from the Unihan database (unicode.org)

    Korean , Vietnamese
        with one of these tags, a keyboard mapping will be generated using Korean or Vietnamese pronunciation as an input method, taking information from the Unihan database (unicode.org)

    VIQR , VNI , Vtelex
        with one of these tags, a keyboard mapping will be generated for the respective Vietnamese input methods, taking character information from the Unicode database (unicode.org)

    script tag
        for many scripts listed in the UnicodeData.txt database, character names listed there can build a useful keyboard mapping; mkkbmap will then generate an according keyboard mapping file, e.g. for Bopomofo
Each successful generation of a mapping table adds an entry to the configuration file keymaps.cfg; the entry is however initially disabled as it usually needs manual adjustment: edit the configuration file; enable the new entry by removing the leading '#' character, check the first element which will be the name of the mapping to appear in the Input Method menu, check the last element of the entry which is a two-letter shortcut and must be unique for all mappings, then move the entry to the position where you want it to appear in the menu. You can also group mappings by adding "-" lines in this configuration file.
For the Unicode data version used for included keyboard mappings, see the mined change log.
For the keyboard mappings generated from Unihan data, characters are sorted according to the priorities of their Unicode ranges (assigning lower priority to "Supplement" and "Extension" and "Compatibility" ranges). So for some input mnemos, the "pick list" for the Cangjie input method is displayed more in order of relevance (since 2000.10).
For keyboard mappings for CJK encodings, mkkbmap will add appropriate punctuation mapping entries for Chinese, Japanese, Korean, respectively, in addition to the entries derived from the respective data source.

  MSDOS-only notes

DOS binaries: Two DOS-based versions, compiled with djgpp and with cygwin, are available for download from the mined web site http://towo.net/mined/ for users who want a quick binary on DOS-based systems. The djgpp binary is a "dual-mode" executable which runs on plain DOS and also supports long file names in a Windows 98/2000/XP/... console window (not NT4.0). It does not run in an xterm, however.

Highlight mode: The ANSI codes for selecting normal and exposed display can be chosen with the environment variable MINEDCOL. The two selections are separated by a space. Each selection is a semicolon-separated list of the code values. The default behaviour corresponds to the setting

    set MINEDCOL=7 27
Example: Green on red text, red on green status:

    set MINEDCOL=34;42 32;44

For command line options, "/" can be used instead of "-".

The "ESC -" command cannot go back within a group of files named by the same wildcard expression. It goes to the previous file name (or wildcard expression) instead.

Enabling the keypad HOP key: If you have a very old and crappy BIOS, you may have to enable use of the cursor block "5" key (for use as a HOP key) with a TSR driver (ENHKBD.COM) or an enhanced keyboard driver. (Older PC keyboard drivers were often so ignorant to forbid you to use that key.)

Immediate adjustment to changed window size does not work in the DOS version if the size change is caused by a TSR (e.g. VGAMAX using a hotkey); in that case, mined adjusts its screen display only after the next key is typed.

The cygwin terminal environment (cygwin in a Windows console window) provides an emulation of a Unix 8 bit character set so non-ASCII characters entered in this version are different from those entered in other DOS-based versions. Editing UTF-8 text, on the other hand, works transparently in all DOS-based versions. See PC terminals above for more details.

In order to enable mouse use in a Windows console window, deactivate "QuickEdit mode" in the properties menu.

    The following only applies if DOS ANSI driver output is used which is currently not the case in any configuration:

    The default colour setting depends on an extended ANSI driver (like NNANSI) as does the scroll down function anyway. Unfortunately, there is no way to find out the current colour setting nor is there an inverse video mode in many ANSI drivers (only a fixed black on white mode) so that it is impossible to implement just inverse display for highlighting. Therefore, if mined thinks to see an ANSI driver of the simpler kind, it will change its colour setting defaults. In any case, these can be overridden with the MINEDCOL variable. Recommended ANSI drivers:

NNANSI by Tom Almy (very capable, but needs some
    installation effort), or

ANSI.COM by Michael J. Mefford (small, works well at
    usual screen sizes).

Mined tries to analyse the ANSI drivers capabilities by checking some control sequences. This works, however, only if the ANSI driver is at least able to send cursor position reports. For primitive ANSI drivers that cannot even do that, mined's operation can be ensured with an emergency procedure: A faked pseudo-report should be stuffed into mined as its first input (with some key-stuffing program) and mined will use no further cursor position requests. It will also assume a simple ANSI driver then. The faked report should consist of the screen size in lines and columns, embedded at the positions of the ANSI cursor report sequence but with different surrounding characters. For an invocation of mined on a 25 lines and 80 columns screen a batch file for this would look like:

    keypress xx25x80xx

    mined %1 %2 %3 %4 %5 %6 %7 %8 %9

The remaining remarks apply to the Turbo-C version only which is no longer supported (use djgpp instead):

    •   The file size being edited is limited to 200KB to 500KB (depending on average line length and number of lines).

    •   Typing of Ctrl-P while display output is active (i.e., during screen paging) can hang the system. Typing of Ctrl-C or Ctrl-Break while display output is active can at least leave some garbage on the screen. Ctrl-S may stop screen output until Ctrl-Q is typed. Typing of Ctrl-P, Ctrl-C, or Ctrl-Break while a search operation is active can be desastrous. (Can anyone tell me how to disable BIOS/MSDOS interpretation of these characters from Turbo-C?)

    •   The Turbo-C version is configured to handle screen output using the "conio" module. (It used to use an ANSI driver.) The disadvantage of conio is that it doesn't handle arbitrary screen modes and sizes whereas good ANSI drivers support them all.

DIAGNOSTICS
In all cases where it is considered sensible, the appropriate message of a system error occurred is displayed (instead of printing numerical hieroglyphs or indistinguished commonplace messages as many other UNIX tools do).

BUGS
In an extremely narrow terminal window (less than 8 characters), if lines are shifted out of the display, moving the cursor around may cause positioning errors and display garbage.

(Unix:) Mined cannot edit a pipe or device file and hangs if you try to do so. (But it can insert from, or write to, a pipe.)
This restriction does not refer to editing from standard input in a piped command like cmd | mined which works of course.

(MSDOS:) Piped editing from standard input does not work for unknown reason. This restriction does not apply to the cygwin version.

(MSDOS, xterm:) Non-cygwin versions (djgpp etc.) do not work in an xterm for unknown reason. The cygwin version does of course work in xterm.

AUTHOR AND ACKNOWLEDGEMENTS
Long ago, the initial version of mined was written for the Minix educational operating system by Michiel Huisjes. It was adapted to Unix by Achim Müller who added termcap support. Mined was later debugged, partly rewritten and enhanced and is now maintained by Thomas Wolff.
