WARNING: (This warning applies to Moodle 1.9.4. It may apply to other versions, but I have not tested to confirm) The GeSHI filter, while it does work, when used in conjunction with the HTML Editor, can be quirky, frustrating, and difficult to use. See my reproducible example, below.
Enclose your code in spans under the source of html editor like so:


Enclose your code in spans like so:
<nowiki><span syntax="code">your code goes here</span></nowiki>
 
<nowiki>[code lang]your code goes here [/code]
[code lang linenumbers]your code with line numbers [/code]
[code lang highlight=1,2,6-9]your code with lines 1, 2 and 6
  to 9 highlighted "extra" [/code]
[code lang linenumbers start=4]start the line numbers at "4" [/code]</nowiki>
 
=== Reproducible Example ===
 
To achieve good results in Moodle 1.9.4+, use the following steps:
 
# Type the GeSHI open/close tags -- "[code php][/code]" -- into the HTML editor (change "php" to another language as required)
#* No quotes, just SQUAREBRACKET-c-o-d-e-SPACE-p-h-p-SQUAREBRACKET
# Highlight these open/close GeSHI tags and choose "preformatted"
# Copy code from textual source
# Paste into HTML editor using source-HTML mode (click the "<>" button to switch modes). Paste '''in-between the [code][/code] brackets'''
# Save and return to course


<nowiki><span syntax="code" linenumbers="yes">your code with line numbers</span></nowiki>

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.

Installing

You can download the GeSHi filter from here:

https://moodle.org/plugins/view.php?plugin=filter_geshi

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 under the source of html editor like so:

<span syntax="code">your code goes here</span>

<span syntax="code" linenumbers="yes">your code with line numbers</span>

Supported languages

and many others. See the GeSHi homepage for full details.

Options

See the examples above. This filter is still under development so things may change.

The GeSHi homepage also has an interactive demo.
