WP-Syntax free WordPress plugin

WP-Syntax provides clean syntax highlighting using
GeSHi — supporting a wide range of popular
languages. It supports highlighting with or without line numbers and maintains formatting while copying snippets of code
from the browser.

It avoids conflicts with other 3rd party plugins by running an early
pre-filter and a late post-filter that substitutes and pulls the code snippets
out first and then pushes them back in with highlighting at the end. The
result is source code formatted and highlighted the way you intended.

Usage, Supported Languages, Styling Guidelines, and Release Notes are available
in the Other Notes section.

Usage

Wrap code blocks with

 and 

where “LANGUAGE” is a GeSHi supported
language syntax. See below for a full list of supported languages.
The line attribute is optional.

Example 1: PHP, no line numbers

Example 2: Java, with line numbers

public class Hello {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}

Example 3: Ruby, with line numbers starting at 18

class Example
  def example(arg1)
    return "Hello: " + arg1.to_s
  end
end

Example 4: If your code already has html entities escaped, use escaped="true" as an option

<xml>Hello</xml>

Example 5: PHP, with line numbers and highlighting a specific line

Example 6: PHP, with a caption (file and/or file path of the source file)

Styling Guidelines

WP-Syntax colors code using the default GeSHi colors. It also uses inline
styling to make sure that code highlights still work in RSS feeds. It uses a
default wp-syntax.css stylesheet for basic layout. To customize your styling,
copy the default wp-content/plugins/wp-syntax/wp-syntax.css to your theme’s
template directory and modify it. If a file named wp-syntax.css exists in
your theme’s template directory, this stylesheet is used instead of the default.
This allows theme authors to add their own customizations as they see fit.

Advanced Customization

WP-Syntax supports a wp_syntax_init_geshi action hook to customize GeSHi
initialization settings. Blog owners can handle the hook in a hand-made plugin
or somewhere else like this:

set_brackets_style('color: #000;');
    $geshi->set_keyword_group_style(1, 'color: #22f;');
}
?>

This allows for a great possibility of different customizations. Be sure to
review the GeSHi Documentation.
