NAME
heme - console hex editor

SYNOPSIS
heme [ -d, --disable-colors ] [ -c, --config-file CONFIGFILE ] [ -n, --no-backup-files ] [ -h, --help ] [ -v, --version ] file

DESCRIPTION
heme is intended to be fast and portable console hex editor for unix systems. It has undo support (number of undo operations is only limited by available memory), ability to fill a range of addresses with the specified byte, ability to search for a single byte or character string. Offsets can be given in hexadecimal, octal or decimal. There are two editing modes: hex and ascii. In hex mode you type hexadecimal digits and in ascii mode you type characters. In the ascii mode cursor is automatically moved to the next byte after typing a character (this behaviour is configurable for hex mode). heme uses curses library for screen and input handling. Colors are supported and they may be configured in the configuration file (see below). If the configuration file isn't present, heme will use defaults. You may also specify which configuration file to use with the -c command line option.

OPTIONS

-n, --no-backup-files
    Don't make backup files.

-c, --config-file CONFIGFILE
    Read configuration from CONFIGFILE. If not given, heme will try to read ~/.hemerc. If that fails, defaults will be used.

-d, --disable-colors
    Don't use colors.

-h, --help
    Show all available command line options.

-v, --version
    Show heme version.

USAGE
Keys (all are case-insensitive, except in the ascii mode):

left (right)
    Move to previous (next) byte

up (down)
    Move to previous (next) line

<   Move to beginning of line

>   Move to end of line

page up
    Move 1 page up

page down
    Move 1 page down

home
    Move to beginning of file

end Move to end of file

h   Display help screen

j   Jump to offset

n (w)
    Search for byte (string)

r   Repeat last search

l   Fill range with byte

tab Toggle between hex and ascii editing modes

u   Undo

s   Save file

q   Quit

CONFIGURATION
Configuration file is expected to reside in ~/.hemerc. The syntax is very simple:
    # this is a comment
    option_1 = value
    option_2 = "value 2" Everything beyond the '#' is considered a comment and is ignored to the end of that line. Supported options are:

use_colors
    Set this to 1 if you want colors, 0 otherwise (default: 1)

advance_after_edit
    Set this to 1 if you want to advance to the next byte after editing byte at the current offset (default: 1)

make_backup_files
    Set this to 1 if you want heme to make backup files, 0 otherwise (default: 1)

bg_color
    Background color (default: "blue")

fg_color
    Foreground color (default: "white")

bg_color_selected
    Background color of selected byte (default: "black")

fg_color_selected
    Foreground color of selected byte (default: "green")

bg_color_status
    Background color of status lines (default: "cyan")

fg_color_status
    Foreground color of status lines (default: "black")

Color names are "black", "red", "green", "yellow", "blue", "magenta", "cyan" and "white".
