# Extension:Code

A MediaWiki extension that builds on [SyntaxHighlight]
to provide the following (all in a configurable manner):

* shorter tags  
  e.g. `<query>` instead of `<syntaxhighlight lang=sparql>`

* code actions  
  e.g. automatically link the [WDQS] for SPARQL code blocks[^1]

* code linkification  
  e.g. automatically link Wikidata identifiers in code blocks

* code pages  
  e.g. automatically higlight pages with names ending in `.rq`
  as SPARQL (and also display the code actions for them)

Note that code actions are also linkable from other pages via the
`Special:CodeAction` special page, e.g. `Special:CodeAction/run/Example.rq`
attempts to execute the `run` action for the `Example.rq` code page
and redirect the user accordingly.

## Installation

1. Place the extension in your extensions directory.
2. Add `wfLoadExtension('Code');` to your `LocalSettings.php`.
3. Visit `Special:CodeAction` it will tell you what other configuration you need.

(If you want syntax highlighting via [SyntaxHighlight], additionally add
`wfLoadExtension('SyntaxHighlight_GeSHi');` to your `LocalSettings.php`).


[^1]: While this can also be achieved just via MediaWiki templates,
this bears the problem that `|` has to be escaped as `{{!}}`, which can
be quite annoying for languages like SPARQL that use `|` as an operator.
