Summary : Wiki using happstack, git or darcs, and pandoc
Description :
Gitit is a wiki backed by a git, darcs, or mercurial filestore. Pages and
uploaded files can be modified either directly via the VCS's command-line
or through the wiki's web interface. Pandoc is used for markup processing,
pages may be written in (extended) markdown, reStructuredText, LaTeX, HTML, or
literate Haskell, and exported in ten different formats, including LaTeX,
ConTeXt, DocBook, RTF, OpenOffice ODT, and MediaWiki markup.

Notable features include

* plugins: dynamically loaded page transformations written in Haskell (see

* conversion of TeX math to MathML for display in web browsers

* syntax highlighting of source code files and code snippets

* Atom feeds (site-wide and per-page)

* a library, "Network.Gitit", that makes it simple to include a gitit
wiki in
any happstack application

You can see a running demo at <http://gitit.net>.
