Pandoc Mediawiki Extension

This is a Mediawiki Extension that translates other doc formats to Mediawiki on runtime.

The main purpose of this extension is to use Markdown semantics on Mediawiki pages!

pandoc must be installed and provided by $PATH env var to use this extension.

Requirements

• pandoc must be installed on the server.
• Output could be different by which pandoc version is installed. (i.e. <syntaxhighlight> vs <source>)
• Tested on Mediawiki 1.35.1, but should work on 1.6.0+

Install

• Download from https://github.com/bekker/pandoc-mediawiki-ext/releases
• Extract this extension into $mw/extensions/Pandoc where $mw is that path to your MediaWiki installation
• Add the following to $mw/LocalSettings.php:

require_once("$IP/extensions/Pandoc/Pandoc.php");

Usage

Default behavior

• This extension tries to guess the format of a page.
• For example, if Atx-style headers(headers using #) are found, the Markdown parser is applied.
• If the guessed format is wrong (which is very likely at the current version) you can specify format by a magic word as described below.
  • Or disable guessing by setting $wgPandocEnableGuess to false.

Declare a magic word at the start of the page

• You can specify which format you want to use.
• Add {{PARSEFROM:<pandoc format name>}} on the page.
• You can set default parsing format with $wgPandocDefaultFormat option. (See below)

Actual content

{{PARSEFROM:gfm}}
## This is Markdown header

- This is __Markdown__ format

What you see (expressed in Mediawiki format)

== This is Markdown header ==

* This is '''Markdown''' format

Mix formats on the same page

• You can add {{PARSEFROM:<pandoc format name>}} in the middle of the page.
• You can add multiple {{PARSEFROM:<pandoc format name>}} on the page.
• Only content below the magic word would be parsed.

__TOC__

* Any Mediawiki grammar here would work!

{{PARSEFROM:gfm}}
## This is Markdown header

- This is __Markdown__ format

{{PARSEFROM:mediawiki}}

* Now Mediawiki again

Aliases

• You can use aliases for specific formats.
• By default following alises are enabled, but you can add one by setting $wgPandocParseWordAlias (See below)
  • {{MARKDOWN}} for Github Flavored Markdown
  • {{WIKI}} for default Mediawiki format.

* Any Mediawiki grammar here would work!
