Text::WikiCreole(3)

NAME
Text::WikiCreole - Convert Wiki Creole 1.0 markup to XHTML

VERSION
Version 0.07

DESCRIPTION
Text::WikiCreole implements the Wiki Creole markup language, version 1.0, as described at http://www.wikicreole.org. It reads Creole 1.0 markup and returns XHTML.

SYNOPSIS
 use Text::WikiCreole;
 creole_plugin \&myplugin; # register custom plugin parser

 my $html = creole_parse($creole_text);
 ...

FUNCTIONS

  creole_parse
    Self-explanatory.  Takes a Creole markup string argument and
    returns HTML.

  creole_plugin
    Creole 1.0 supports two plugin syntaxes: << plugin content >> and
                                            <<< plugin content >>>

    Write a function that receives the text between the <<>>
    delimiters as $_[0] (and not including the delimiters) and
    returns the text to be displayed.  For example, here is a
    simple plugin that converts plugin text to uppercase:

    sub uppercase_plugin {
      $_[0] =~ s/([a-z])/\u$1/gs;
      return $_[0];
    }
    creole_plugin \&uppercase_plugin;

    If you do not register a plugin function, plugin markup will be left
    as is, including the surrounding << >>.

  creole_link
    You may wish to customize [[ links ]], such as to prefix a hostname,
    port, etc.

    Write a function, similar to the plugin function, which receives the
    URL part of the link (with leading and trailing whitespace stripped)
    as $_[0] and returns the customized link.  For example, to prepend
    "http://my.domain/" to pagename:

    sub mylink {
      return "http://my.domain/$_[0]";
    }
    creole_link \&mylink;

  creole_customlinks
    If you want complete control over links, rather than just modifying
    the URL, register your link markup function with creole_link() as above
    and then call creole_customlinks().  Now your function will receive the
    entire link markup chunk, such as [[ some_wiki_page | page description ]]
    and must return HTML.

    This has no effect on "bare" link markup, such as http://cpan.org.

  creole_barelink
    Same purpose as creole_link, but for "bare" link markup.

    sub mybarelink {
      return "$_[0].html";
    }
    creole_barelink \&mybarelink;

  creole_custombarelinks
    Same purpose as creole_customlinks, but for "bare" link markup.

  creole_img
    Same purpose as creole_link, but for image URLs.

    sub myimg {
      return "http://my.comain/$_[0]";
    }
    creole_img \&myimg;

  creole_customimgs
    Similar to creole_customlinks, but for images.

  creole_tag
    You may wish to customize the opening and/or closing tags
    for the various bits of Creole markup.  For example, to
    assign a CSS class to list items:

    creole_tag("li", "open", "<li class=myclass>");

    Or to see all current tags:

    print creole_tag();

    The tags that may be of interest are:

    br          dd          dl
    dt          em          h1
    h2          h3          h4
    h5          h6          hr
    ilink       img         inowiki
    ip          li          link
    mono        nowiki      ol
    p           strong      sub
    sup         table       td
    th          tr          u
    ul

    Those should be self-explanatory, except for inowiki (inline nowiki),
    ilink (bare links, e.g. http://www.cpan.org), and ip (indented paragraph).

OFFICIAL MARKUP
    Here is a summary of the official Creole 1.0 markup
    elements.  See http://www.wikicreole.org for the full
    details.

    Headings:
    = heading 1       ->    <h1>heading 1</h1>
    == heading 2      ->    <h2>heading 2</h2>
    ...
    ====== heading 6  ->    <h6>heading 6</h6>

    Various inline markup:
    ** bold **        ->    <strong> bold </strong>
    // italics //     ->    <em> italics </em>
    **// both //**    ->    <strong><em> both </em></strong>
    [[ link ]]        ->    <a href="link">link</a>
    [[ link | text ]] ->    <a href="link">text</a>
    http://cpan.org   ->    <a href="http://cpan.org">http://cpan.org</a>
    line \\ break     ->    line <br /> break
    {{img.jpg|alt}}   ->    <img src="img.jpg" alt="alt">

    Lists:
    * unordered list        <ul><li>unordered list</li>
    * second item               <li>second item</li>
    ## nested ordered  ->       <ol><li>nested ordered</li>
    *** uber-nested                 <ul><li>uber-nested</li></ul>
    * back to level 1           </ol><li>back to level 1</li></ul>

    Tables:
    |= h1 |= h2       ->    <table><tr><th>h1</th><th>h2</th></tr>
    |  c1 |  c2             <tr><td>c1</td><td>c2</td></tr></table>

    Nowiki (Preformatted):
    {{{                     <pre>
      ** not bold **          ** not bold **
      escaped HTML:   ->      escaped HTML:
      <i> test </i>           &lt;i&gt; test &lt;/i&gt;
    }}}                     <pre>

    {{{ inline\\also }}} -> <tt>inline\\also</tt>

    Escape Character:
    ~** not bold **    ->    ** not bold **
    tilde: ~~          ->    tilde: ~

    Paragraphs are separated by other blocks and blank lines.
    Inline markup can usually be combined, overlapped, etc.  List
    items and plugin text can span lines.

EXTENDED MARKUP
    In addition to OFFICIAL MARKUP, Text::WikiCreole also supports
    the following markup:

    Plugins:
    << plugin >>        ->    whatever you want (see creole_plugin above)
    <<< plugin >>>      ->    whatever you want (see creole_plugin above)
        Triple-bracket syntax has priority, in order to allow you to embed
        double-brackets in plugins, such as to embed Perl code.

    Inline:
    ## monospace ##     ->    <tt> monospace </tt>
    ^^ superscript ^^   ->    <sup> superscript </sup>
    ,, subscript ,,     ->    <sub> subscript </sub>
    __ underline __     ->    <u> underline </u>
    (TM)                ->    &trade;
    (R)                 ->    &reg;
    (C)                 ->    &copy;
    ...                 ->    &hellip;
    --                  ->    &ndash;

    Indented Paragraphs:
    :this               ->    <div style="margin-left:2em"><p>this
    is indented               is indented</p>
    :: more indented          <div style="margin-left:2em"><p> more
                              indented</div></div>

    Definition Lists:
    ; Title             ->    <dl><dt>Title</dt>
    : item 1 : item 2         <dd>item 1</dd><dd>item 2</dd>
    ; Title 2 : item2a        <dt>Title 2</dt><dd>item 2a</dd></dl>
