Extension:CodeEditor/en


 * Not to be confused with CodeMirror.

The CodeEditor extension extends the WikiEditor advanced editing toolbar with an embedded Ace editor widget, providing some handy features for user/site JavaScript pages, CSS pages, JSON pages, and when extension is also installed, for Lua pages, i.e. pages in the Module namespace. The code editor does not show on regular wiki pages, i.e. wiki pages with the "wikitext" content model. (See for syntax highlighting of wikitext when using the source editor.)

It provides the following features:


 * syntax highlighting for JavaScript, CSS and Lua
 * auto-indent
 * tab key produces tab indents (since 1.22), soft indents before.
 * indent/unindent selection with Tab/Shift-Tab keys
 * syntax validity check for JavaScript
 * Pair-matching for parenthesis, braces and square brackets
