| You can color or highlight code snippets within Moodle resources, forum posts etc. To do so you must install the GeSHi (Generic Syntax Highlighter) Filter. This makes the power of GeSHI available in Moodle through the use of a pair of special tags.
| | There used to be [https://moodle.org/plugins/view.php?plugin=filter_geshi filter_geshi] available for the syntax highlighting but is was [https://tracker.moodle.org/browse/CONTRIB-8002 removed]. |
| | | See [[MoodleDocs:Style_guide#PHP_syntax_highlighting]] that does not need any additional filter |

| |
| | |
| You can download the GeSHi filter from here:
| |
| | |
| http://geshi.org/downloads/moodle-geshi-filter-0.1.0.zip

| To install, unzip that archive into your filter/ directory and then enable it in the admin filter configuration screen.
| |
| | |
| == Instructions for use ==

| | |
| Enclose your code in spans like so:
| |
