The SyntaxHighlight extension, formerly known as SyntaxHighlight_GeSHi, provides rich formatting of source code using the <syntaxhighlight>
tag.
It is powered by the Pygments library and supports hundreds of different programming languages and file formats.
Like the <pre>
and <poem >
tags, the text is rendered exactly as it was typed, preserving any white space.
The SyntaxHighlight extension does not work on wiki installations hardened using Hardened-PHP due to the lack of proc_open
, shell_exec
and other functions.
See task T250763.
The <syntaxhighlight>
tag has become expensive since 1.39 for 5,000 or some other extreme amount of syntaxhighlight tags in a single page such as for Wikibooks.
Increase webserver timeout value in environments in extreme cases.
(See task T316858.)
Выкарыстаньне
Once installed, you can use "syntaxhighlight" tags on wiki pages. For example,
def quick_sort(arr):
less = []
pivot_list = []
more = []
if len(arr) <= 1:
return arr
else:
pass
is the result of the following wikitext markup:
<syntaxhighlight lang="python" line>
def quick_sort(arr):
less = []
pivot_list = []
more = []
if len(arr) <= 1:
return arr
else:
pass
</syntaxhighlight>
In older versions (before MediaWiki 1.16), the extension used the tag <source>
.
This is still supported, but is deprecated. <syntaxhighlight>
should be used instead.
Стыляваньне
If the displayed code is too big, you can adjust it by putting the following into the MediaWiki:Common.css page in your wiki (create it if it does not exist):
/* CSS placed here will be applied to all skins */
.mw-highlight pre {
font-size: 90%;
}
Encasing code blocks in borders can be done by inserting a line like border: 1px dashed blue;
in the section above.
Control over font family used can also be exercised by inserting a line like font-family: "Courier New", monospace;
into the section above.
Катэгорыя памылковых падсьветак сынтаксу
The extension adds pages that have a bad lang
attribute in a <syntaxhighlight>
tag to a tracking category.
The message key MediaWiki:syntaxhighlight-error-category determines the category name; on this wiki it is Category:Pages with syntax highlighting errors.
The most common error that leads to pages being tagged with this category is a <syntaxhighlight>
tag with no lang
attribute at all, because older versions of this extension supported the definition of $wgSyntaxHighlightDefaultLang
.
These can typically either be replaced with <pre>
, or lang="bash"
or lang="text"
can be added to the tag.
The category may also be added, and the content will not be highlighted, if there are more than 1000 lines or more than 100 kB text.[1]
Парамэтры
lang
The lang="name"
attribute defines what lexer should be used.
The language affects how the extension highlights the source code.
See the section #Supported languages for details of supported languages.
def quick_sort(arr):
less = []
<syntaxhighlight lang="python">
...
</syntaxhighlight>
Specifying an invalid or unknown name will tag the page with a tracking category. Падрабязнасьці глядзіце ў сэкцыі Катэгорыя старонак з памылкамі падсьветкі сынтаксісу гэтай старонкі.
line
The line
attribute enables line numbers.
def quick_sort(arr):
less = []
<syntaxhighlight lang="python" line>
...
</syntaxhighlight>
start
The start
attribute (in combination with line
) defines the first line number of the code block.
For example, line start="55"
will make line numbering start at 55.
def quick_sort(arr):
less = []
<syntaxhighlight lang="python" line start="55">
...
</syntaxhighlight>
highlight
The highlight
attribute specifies one or more lines that should be marked (by highlighting those lines with a different background color).
You can specify multiple line numbers separated by commas (for example, highlight="1,4,8"
) or ranges using two line numbers and a hyphen (for example, highlight="5-7"
).
start
attribute.def quick_sort(arr):
less = []
pivot_list = []
more = []
if len(arr) <= 1:
return arr
is the result of
<syntaxhighlight lang="python" line start="3" highlight="1,5-7">
...
</syntaxhighlight>
inline
MediaWiki version: | ≥ 1.26 |
The attribute indicates that the source code should be inline as part of a paragraph (as opposed to being its own block). This option is available starting with MediaWiki 1.26.
class="nowrap"
(on those wikis that support it; see below) or style="white-space:nowrap"
.For example:
The following lambda x: x * 2
is a lambda expression in Python.
Is the result of:
The following <syntaxhighlight lang="python" inline>lambda x: x * 2</syntaxhighlight> is a [[w:Lambda (programming)|lambda expression]] in Python.
class
When inline
is used, class="nowrap"
(on those wikis that support it; not on MediaWiki itself) specifies that line breaks should not occur at spaces within the code block.
For example:
Without class="nowrap"
:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxlambda x: x * 2
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
With style="white-space:nowrap"
:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxlambda x: x * 2
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
style
The style
attribute allows CSS attributes to be included directly.
This is equivalent to enclosing the block in a <div>
(not <span>
) tag.
The tab‑size
attribute cannot be specified this way; it requires an enclosing <span>
tag as described below under Advanced.
For example:
def quick_sort(arr):
less = []
pivot_list = []
more = []
if len(arr) <= 1:
return arr
else:
pass
Is the result of:
<syntaxhighlight lang="python" style="border: 3px dashed blue;">
def quick_sort(arr):
less = []
pivot_list = []
more = []
if len(arr) <= 1:
return arr
else:
pass
</syntaxhighlight>
copy
MediaWiki version: | ≥ 1.43 |
The copy
attribute adds a button link that copies the content to the clipboard when clicked.
inline
will be respected.For example:
def quick_sort(arr):
less = []
Is the result of:
<syntaxhighlight lang="python" copy>
def quick_sort(arr):
less = []
</syntaxhighlight>
Падтрымка моваў
Pygments provides support for syntax-highlighting hundreds of computer languages and file formats through the various "lexers" included with the library.
In most cases, the lang=
attribute to be used with this extension is the lower-case version of the name of the language.
However, many have aliases, or "short names" as they're called in the Pygments documentation; see "Available lexers" for full details.
Some languages previously supported by GeSHi have been mapped to Pygments lexers; see SyntaxHighlightGeSHiCompat.php
for details.

python3
) to be installed on the server. This is a change from the version bundled with MediaWiki 1.30, which used Python version 2 (python
). Note that the python3
binary must be installed in the execution PATH of the PHP interpreter.- Download and move the extracted
SyntaxHighlight_GeSHi
folder to yourextensions/
directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/SyntaxHighlight_GeSHi - Only when installing from Git, run Composer to install PHP dependencies, by issuing
composer install --no-dev
in the extension directory. (See task T173141 for potential complications.) - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'SyntaxHighlight_GeSHi' );
- In Linux, set execute permissions for the pygmentize binary.
You can use an FTP client or the following shell command to do so:
chmod a+x /path/to/extensions/SyntaxHighlight_GeSHi/pygments/pygmentize
- Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Vagrant installation:
- If using Vagrant , install with
vagrant roles enable syntaxhighlight --provision
So, after installation from Git change to the directory containing the extension e.g.
"../extensions/SyntaxHighlight_GeSHi/"
and run composer install --no-dev
, or when updating: composer update --no-dev
.Alternatively as well as preferably add the line
"extensions/SyntaxHighlight_GeSHi/composer.json"
to the "composer.local.json" file in the root directory of your wiki like e.g.
{
"extra": {
"merge-plugin": {
"include": [
"extensions/SyntaxHighlight_GeSHi/composer.json"
]
}
}
}
Now run composer update --no-dev
.

.
- Windows
- If you are hosting your MediaWiki on a Windows machine, you have to set the path for the Pygmentize.exe
$wgPygmentizePath = "c:\\Python27\\Scripts\\pygmentize.exe";

If you are using the bundled pygmentize binary (extensions/SyntaxHighlight_GeSHi/pygments/pygmentize), make sure your webserver is permitted to execute it.
If your host does not allow you to add executables to your web directory, install python-pygments and add $wgPygmentizePath = pygmentize
to LocalSettings.php
.
- Troubleshooting
After updating to MediaWiki v1.26 and above, some users started reporting problems with the extension.
Могуць быць выпадкі, калі асобныя мовы, напрыклад Lua, не падсьвечваюцца, а пры ўключэньні адладкі MediaWiki выдае памылку Notice: Failed to invoke Pygments: /usr/bin/env: python3: No such file or directory
.
- Try pointing
$wgPygmentizePath
inLocalSettings.php
towards an external pygmentize binary.
- In shared hosting environments with cPanel, this can be done by setting up a new Python application through the "Setup Python App" menu, and activating the virtual environment for the app through SSH (
source /virtualenv/python/3.5/bin/activate
). After this, the Pygments module can be added to the Python app, for which navigate to the virtual environment path (cd virtualenv/python/3.5/bin/
), download and install Pygments (./pip install Pygments
) and then activate the module by adding "Pygments" under the "Existing applications" section of the "Setup Python App" menu. This will create the required file at path:virtualenv/python/3.5/bin/pygmentize

in your audit.log. This can be allowed withsetsebool -P httpd_unified 1
- In earlier versions of this extension, Windows would sometimes fail with an _Py_HashRandomization_Init error. This was a bug with the Windows environment not being passed to python executions. A fix was released in 1.40, with backports to 1.38 and 1.39.

The plugin enables direct editing with VisualEditor.
A popup is opened when a user wants to edit syntaxhighlight
sections.
For this to work, VisualEditor must be installed and configured from the latest Git version, same for Parsoid.
The feature may not work with older Parsoid versions.

Like the <pre>
tag but unlike the <code>
tag, tags within the range (other than its own closing tag) need not have the <
symbol escaped as <
, nor does wikitext need to be escaped with a <nowiki>
tag.
Furthermore, while <pre>
assumes tab stops every 8 characters and renders tabs using actual spaces when the rendered text is copied, <syntaxhighlight>
uses 4-space tab stops (except Internet Explorer, which uses 8) and preserves the tab characters in the rendered text; the latter may be changed using an enclosing <span style="-moz-tab-size: nn; -o-tab-size: nn; tab-size: nn;">
tag (not <div>
, and not using its own style
attribute).
The -moz-
prefix is required for Firefox (from version 4.0 to version 90), and the -o-
prefix is required for Opera (from version 10.60 to version 15).[2]
(Note that the wiki editing box assumes 8-space tabs.)
This applies only to actual saved pages; previews generated through an edit box or Special:ExpandTemplates may differ.
