This module integrates the SyntaxHighlighter Javascript Library into Drupal for source code list syntax highlighting within any Drupal contents.

Note: the SyntaxHighlighter Javascript library is not included and must be downloaded and installed in sites/all/libraries. See README.txt for more details. This module is compatible with both the 2.x and 3.x versions of the Javascript library.

To markup your code, use the <pre> tag with the class attribute and optionally the title attribute. See the <pre /> method section on this page and the configuration page for exact/complete explanation.:

<pre class="SYNTAXHIGHLIGHTER-OPTIONS" title="My title">
  program code

Very important!!!: ordered the input format filters as follow:

  1. HTML filter or Wysiwyg filter or whatever HTML filters you use. They must come before.
  2. Syntax highlighter. This come after any and all filters that can modify content input.
  3. Line break converter. This must be after, If you see <br/> at the end of every line in your output, then you know what's wrong.

Note: Ajax and autoloader do not work together. If you Ajax load syntax highlighted code, do not enable Autoloader. Or you must make sure the initial page load already has the language brush loaded.

D7 update of this module see

TinyMCE SyntaxHighlighter

D7 WYSIWYG intergration:

Old 1.x branch:

In the 1.x branch, the <pre> tag format is only suitable for the Full HTML format. This is because of the unusual class string format (i.e. class="brush:php;gutter:false"), both the HTML filter and the WYSIWYG Filter filter out the class string as something illegal and not allowed. The final output end up with no class attribute. To get around this, instead of using the pre tag, this format is used:

{syntaxhighlighter class="SYNTAXHIGHLIGHTER-OPTIONS" [title="title"]}
  program code

This {} format makes things compatible with the built-in HTML filter and the WYSIWYG Filter.

Old D6 1.x {syntaxhighlighter} to <pre> to D7 automatic conversion:

konstantin.komelin has created the {syntaxhighlighter} to PRE Converter module to automate the conversion from D6 1.x branch format to D7.

If you already use the D6 2.x version, then you don't need any conversion to move to D7.

See more details and a demo of this module.

Install the Multicolumncheckboxesradios module and the checkall module to enhance the settings form.
