Extension talk:SyntaxHighlight

Copy Tag

Just thought I would note here since this is a protected page. But for the navigator.clipboard to work, for the copy tag, the wiki must be using HTTPS, and the user must be connected using https as well. 2600:1004:B302:FF51:DC98:EFA4:CC86:4B9D 14:06, 14 January 2025 (UTC)

Which I know is a standard nowadays, but just thought it would be a good note for private wiki’s that aren’t public facing 2600:1004:B302:FF51:DC98:EFA4:CC86:4B9D 14:10, 14 January 2025 (UTC)

Error category for every page

MediaWiki: 1.43.5
PHP: 8.2.28 (fpm-cgi)
Pygments: 2.19.2
SyntaxHighlight: 2.0

Every page, I use SyntaxHighlight on, get's added to the "syntax error category". Even if I use a simple example like

<syntaxhighlight lang="text">
test
</syntaxhighlight>

If I use the example from the extensions page, the category is added too and there are no line numbers shown.

<syntaxhighlight lang="python" line>
def quick_sort(arr):
	less = []
	pivot_list = []
	more = []
	if len(arr) <= 1:
		return arr
	else:
		pass
</syntaxhighlight>

Using debug mode I found the following lines:

[warning] Failed to invoke Pygments: Traceback (most recent call last):

ModuleNotFoundError: No module named 'importlib.metadata'

Could this be the reason? I am trying to install this package at the moment, but the server has no internet connection. So no idea if this will work.

Your version of Python is too old for your version of Pygments. Try upgrading your Python to at least 3.8. * Pppery * _{it has begun} 15:04, 29 December 2025 (UTC)

This could prove difficult. But I'll try. Thanks for the tip! Drhirn (talk) 09:03, 30 December 2025 (UTC)

If you are stuck on an unsupported version of Python for some reason there are two possible solutions. The first is to downgrade to an older version of the SyntaxHighlight extension. The Python 3.8 requirement comes from Pygments 2.18.0 which we introduced in June 2025.

The second option would be to use the Docker container we produce for Wikimedia's content wikis to run the Pygments binary via Shellbox. There are basic instructions on setting up a wiki to use Shellbox for SyntaxHighlight at MediaWiki-Docker/Extension/SyntaxHighlight#Run from Shellbox container. The specifics about your Docker runtime would likely be different, but the core workflow of running docker-registry.wikimedia.org/httpd-fcgi:latest plus docker-registry.wikimedia.org/wikimedia/mediawiki-libs-shellbox:syntaxhighlight83 would be the same outside of a MediaWiki-Docker development environment. -- BDavis (WMF) (talk) 20:55, 5 January 2026 (UTC)
