This is an administrative category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories (except for eponymous maintenance categories).

This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme.

• This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
• These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
• These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category as empty!

This category may be empty occasionally or even most of the time.

This category contains pages with <syntaxhighlight> calls which have encountered errors in parsing, or where the tagged material is too large.

To correct errors, just define a known computing language name as an attribute of the <syntaxhighlight lang="..."> tag. Setting it to text suppresses all errors. Some languages are not yet supported. If the language is valid, do not change or remove the name of the language just to remove the maintenance category. The real fix is to get the language supported by Pygments.

The current size limits are 1,000 lines or 102,400 bytes.

This category is sorted by page name and ignores the namespace. This search only displays articles in the category (may include recently removed articles).

Many languages (mostly obscure) were de-supported due to the switch from GeSHi to Pygments for syntax highlighting (phab:T85794). Fallbacks may be added to SyntaxHighlight_GeSHi.compat.php where languages are sufficiently similar. For unsupported commonly used languages, please contribute language definitions to Pygments. See also phab:T105889.
