## Description

This plugin is a syntax highlighter for source code. It uses _GeSHi_ as fontifier
engine.

#### Usage

 1. Put the code snippet in a “` tag.
 2. Add the lang attribute to the code tag like the following. `<code lang="php">`
 3. Add the lineno attribute to the `<code>` tag after the lang tag if you wish to 
    start at a line other than 1. `<code lang="cpp" lineno="42">`
 4. If you do not add lang attribute, the `<code>` tag is handled normally.
 5. If you want to have border, add the style like the following to your .css file.`
    code { border: 1px dotted #ccc; padding: 0.2em 0.5em; }`
 6. You can use following languages in lang. `abap, actionscript, ada, apache, applescript,
    asm, asp, autoit, bash, blitzbasic, bnf, c, c_mac, caddcl, cadlisp, cfdg, cfm, 
    cpp-qt, cpp, csharp, css-gen, css, d, delphi, diff, div, dos, dot, eiffel, fortran,
    freebasic, genero, gml, groovy, haskell, html4strict, idl, ini, inno, io, java,
    java5, javascript, latex, lisp, lua, m68k, matlab, mirc, mpasm, mysql, nsis, objc,
    ocaml-brief, ocaml, oobas, oracle8, pascal, per, perl, php-brief, php, plsql, python,
    qbasic, rails, reg, robots, ruby, sas, scheme, sdlbasic, smalltalk, smarty, sql,
    tcl, text, thinbasic, tsql, vb, vbnet, vhdl, visualfoxpro, winbatch, xml, xpp, 
    z80`

**Note:** Version 1.9 adds support for `<code>` tags, however to ensure backwards
compatibility support for the `<pre>` tag will not be removed.

### Known issues

 1. Because this plugin uses regular expression to match string range from `<code lang
    ="some">` to “`, you can’t use `</code>` in your code snippet. If you must put 
    the `</code>` tag, you can put a space between `<` and `/code>` like `< /code>`.
    The `< /code>` is converted to `</code>` automatically by plugin.
 2. If you want to change the style, you should modify the plugin source file. 😛

## Installation

 1. Unzip the plugin archive.
 2. Upload the directory to the `/wp-content/plugins/` directory
 3. Activate the plugin through the ‘Plugins’ menu in WordPress
