Extension:Highlightjs Integration

The Highlightjs Integration extension is a drop-in replacement for the SyntaxHighlight extension. Instead of using Pygments as server-side highlighter, it uses highlight.js a client-side JavaScript highlighter. It makes the wikis which use a lot of syntax highlighting faster.

Usage
Once installed, you can use the "syntaxhighlight" or the "source" tags on wiki pages. For example,

lang
If no "lang" attribute is defined, the highlight.js library tries itself to determine the language.

The  attribute defines what lexer should be used. This affects how the extension highlights the source code.

The highlight.js library supports 176 languages. Specifying an invalid or unknown name will make the highlight.js library unable to highlight the source code.

inline
The attribute indicates that the source code should be inline as part of a paragraph (as opposed to being its own block). For example:

on one line.

Style
The highlight.js library supports color themes.

To change theme edit the file  and modify the line

Tags
By default you can use the  or the   tags to highlight source code.

To add other tags or remove some, edit the file  and modify the following block:

Mapping between languages
If you used SyntaxHighlight, you will find some languages have different names in the highlight.js library and some have missing.

To map a language name to an existing language in the highlight.js library, edit the file  and modify the following block:

highlight.js
This extension is bundled with highlight.js version 11.5.1 and the common languages.

Bug Uncaught SyntaxError: unterminated regular expression literal
The load of the  script in this extension raises a syntax error. As a workaround, the  script is loaded from the CDNJS url instead of the file provided with this extension.

Update HighlightJS
If you want a different version of the highlight.js library or add / remove languages:
 * 1) go on the download page of the highlight.js website and download a custom package.
 * 2) remove or rename the   folder.
 * 3) unarchive the custom package in  . You should have a fresh new   folder.

To use the bundled  script and not the one from CDNJS:

hljs.configure({  cssSelector: 'pre.code2highlight, code.code2highlight, pre.mwcode' });
 * replace the content of the  file by the following code

hljs.highlightAll;

"ResourceModules": { "ext.HighlightjsIntegration": { "scripts": [ "highlight/highlight.min.js", "init.js" ]   } },
 * update the  file by adding   in the scripts to load in this extension
