Descrição
CodeColorer lets you insert syntax-highlighted code snippets into posts, comments, and feeds.
CodeColorer currently bundles GeSHi 1.0.9.0 from the upstream 1.0.x line, with a small set of project-local maintenance patches for current PHP and WordPress compatibility.
Plugin based on GeSHi library, which supports most languages. CodeColorer has various nice features:
- syntax highlighting in RSS feeds
- syntax highlighting of a single line of code (inline)
- syntax highlighting of code in comments
- line numbers
- automatic links to the documentation inserting
- code block intelligent scroll detection (short code would have a short block, for a long one the block height would be fixed and a scrollbar would appear)
- predefined color themes (Slush & Poppies, Blackboard, Dawn, Mac Classic, Twitlight, Vibrant Ink, Railscasts, Solarized Light, Solarized Dark)
- syntax colors customization in CSS file
- code protect from mangling by WordPress (for example, quotes, double-dashes, and others would look just right as you entered)

Sources of this plugin are available both in SVN and Git:
The GitHub repository includes local contributor tooling based on mise, Composer, pnpm, and wp-env. A typical setup is:
mise installmise run bootstrapmise run testmise run wp-start
Feel free to check them out, make your changes and send me patches or pull requests. Promise, I will apply every patch (of course, if they add a value to the product). Email for patches, suggestions, or bug reports: [email protected].
If you’re interested in translating CodeColorer to your language, please check out the translation page for the plugin.
Customization
Syntax coloring is highly customizable: you could change the color scheme for all languages or a specific language. You could find CodeColorer CSS in wp-content/plugins/codecolorer/codecolorer.css file. To change colors for all languages edit lines below Color scheme section.
There is a simple mapping between TextMate color themes and CodeColorer ones:
/* "Slush & Poppies" color scheme (default) */
.codecolorer-container, .codecolorer { color: #000000; background-color: #F1F1F1; }
/* Comment */
.codecolorer .co0, .codecolorer .co1, .codecolorer .co2, .codecolorer .co3, .codecolorer .co4, .codecolorer .coMULTI { color: #406040; font-style: italic; }
/* Constant */
.codecolorer .nu0, .codecolorer .re3 { color: #0080A0; }
/* String */
.codecolorer .st0, .codecolorer .st_h, .codecolorer .es0, .codecolorer .es1 { color: #C03030; }
/* Entity */
.codecolorer .me1, .codecolorer .me2 { color: #0080FF; }
/* Keyword */
.codecolorer .kw1, .codecolorer .kw2, .codecolorer .sy1 { color: #2060A0; }
/* Storage */
.codecolorer .kw3, .codecolorer .kw4, .codecolorer .kw5, .codecolorer .re2 { color: #008080; }
/* Variable */
.codecolorer .re0, .codecolorer .re1 { color: #A08000; }
/* Global color */
.codecolorer .br0, .codecolorer .sy0 { color: #000000; }
Check the codecolorer.css file to get more examples.

Instalação
- Download and unpack plugin files to wp-content/plugins/codecolorer directory.
- Enable CodeColorer plugin on your Plugins page in Site Admin.
- Go to the Settings > CodeColorer page in Site Admin and change the plugin options as you wish.
- Use
[cc lang="lang"]code[/cc]or<code lang="lang">code</code>syntax to insert a code snippet into the post (you can skiplang="lang"if you want a plain CodeColorer block without syntax highlighting). You can also use[cci lang="lang"]code[/cci]to format inline code (see the “inline” option description). - Have fun!
Syntax
To insert a code snippet into your post (or comment) you can use [cc lang="lang"]code[/cc] or <code lang="lang">code</code> syntax. Starting from version 0.6.0 you can specify additional CodeColorer options inside the [cc] tag:
[cc lang="php" tab_size="2" lines="40"]
// some code
[/cc]
Note: You should always use double quotes or single quotes around the parameter value. Boolean values could be passed using string true or false, on or off, number 1 or 0.
Shortcodes
Starting from CodeColorer 0.8.6 you can use shortcodes to insert code snippets. The general form looks like [ccM_LANG], where LANG is your programming language, and M is one or more of the following modes:
- i – inline
- e – escaped
- s – strict
- n – line_numbers
- b – no_border
- w – no_wrap
- l – no_links
Small letter means enabled, capital – disabled. Examples:
PHP code with links enabled and line numbers disabled:
[cclN_php]
echo "hello"
[/cclN_php]
Already escaped HTML code:
[ccie_html]<html>[/ccie_html]
Ruby code without wrapping having tab size equal to 4:
[ccW_ruby tab_size="4"]
attr_accessor :title
[/ccW_ruby]
More examples could be found on the CodeColorer Examples page. You can find modes explained below.
Possible parameters
- lang (string) – source language.
- tab_size (integer) – how many spaces would represent TAB symbol.
- lines (integer) – how many lines would be block height without scroll; could be set to -1 to remove vertical scrollbar.
- width (integer or string) – block width.
- height (integer or string) – height in pixels; used when the number of lines is greater than the “lines” value.
- rss_width (integer or string) – block width in RSS feeds.
- theme (string) – color theme (default, blackboard, dawn, mac-classic, twitlight, vibrant, geshi, railscasts, solarized-light, solarized-dark).
- first_line (integer) – a number of the first line in the block.
- highlight (string) — a comma-separated list of line numbers or ranges of line numbers to highlight (e.g.
1,5,8-11). - escaped (boolean) – when true special HTML sequences like
<or[will be treated as encoded (in this example as<and[respectively.) - line_numbers (boolean) – when true line numbers will be added.
- no_links (boolean) – when false keywords will be represented as links to manual.
- inline (boolean) – when true forces code block to render inside “`. Used to paste a single line of code into the regular text.
- strict (boolean) – when true strict mode will be enabled. By default CodeColorer tries to guess whether strict mode is needed, so this option allows to force it on or off when automatic suggestion is wrong.
- nowrap (boolean) – when false no horizontal scrollbar will be shown; instead code will be wrapped in the end of code box.
- noborder (boolean) – when true no border will be shown around the code block.
- no_cc (boolean) – when true the syntax in code block will not be highlighted, code will be rendered inside `
`` tag. - class (string) – additional CSS classes to add to the wrapper HTML element.
- file (string) — when specified, code will be loaded from external file. Should be a relative to uploads folder path, only files from uploads are allowed to be embedded.
You can use special tag [cci] instead of [cc] to force inline mode:
[cci lang="php"]some code[/cci]
Most of these parameters could be configured via the CodeColorer options page.
To insert an example of CodeColorer shortcodes you can use something like this:
[cce_bash]
&#91;cc lang="html"]
<title>CodeColorer short code colorized</title>
&#91;/cc]
[/cce_bash]

I have updated the plugin to the newest version and now I keep getting following warnings:
-
Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/wordpress/wp-content/plugins/codecolorer/lib/geshi.php on line 3599
Remove all files from the wp-content/plugins/codecolorer folder and unpack an archive with plugin again (thanks to Anatoliy ‘TLK’ Kolesnick).
-
How do I insert code from an external file?
-
You can upload this file with the WordPress uploader or put it somewhere in the uploads folder, and then specify the relative path with the
file="relative/path/to/file"attribute:[cc_ruby file="test_project/main.rb"][/cc_ruby]This snippet will insert code from the UPLOADS_DIR/test_project/main.rb file.
-
Google Website Translator breaks my code blocks
-
The solution is to add
notranslateclass to the list of “Custom CSS Classes” on the admin plugin settings page. -
