Alternative parsers

Jump to: navigation, search

This page is a compilation of links, descriptions, and status reports of the various alternative MediaWiki parsers—that is, programs and projects, other than MediaWiki itself, which are able or intended to translate MediaWiki's text markup syntax into something else. Some of these have quite narrow purposes, others are possible contenders for replacing the somewhat labyrinthine code that currently drives MediaWiki itself.

Many of the things linked here are likely to be out of date and under-maintained, even abandoned. But in the interest of not duplicating the same work over and over, it seemed sensible to collect together what was "out there".

A non-parser dumper[edit]

One of the common uses of alternative parsers is to dump wiki content into static form, such as HTML or PDF. Tim Starling has written a script which isn't a parser, but uses the MediaWiki internal code to dump an entire wiki to HTML, from the command-line. See Extension:DumpHTML. This has been used (years ago) to create the static dumps at
