I need groovy highlighting in pandoc.

Quick explanation: Pandoc use Kate’s syntax description files to make is own syntax highlighter. This is perform in sub-project highlighting-kate. For the moment, pandoc supports 96 languages but kate supports 231 languages.

You can follow this short howto to append new languages highlighting in pandoc.

First retrieve and compile highlighting-kate subproject

First we need to install Haskell and cabal.

sudo apt-get instal haskell-platform
sudo apt-get instal cabal-build

Then we can download highlighting-kate subproject and try to compile it.

git clone https://github.com/jgm/highlighting-kate.git
cd highlighting-kate
cabal update
cabal install

Highlight is now install in ~/.cabal/bin/

~/.cabal/bin/Highlight -s haskell Text/Highlighting/Kate.hs > example.html

Second a new Highlighting definition

Second step we will add a new language. What I need is Groovy Highlighting, not currently available in kate :-(, but I found a definition on groovy plugins page:

wget http://docs.codehaus.org/download/attachments/2747/groovy.xml
mv groovy.xml xml/
cabal install
~/.cabal/bin/Highlight -s groovy sample.groovy > example.html

Very easy isn’t it ?

Compile own pandoc

Third step, compile pandoc with our new definition. Thanks to cabal our updated Highlight is on local repository. So we simply need to run cabal install

git clone --recursive https://github.com/jgm/pandoc.git
cd pandoc
cabal install

~/.cabal/bin/pandoc --version

This takes some time but works like a charm.

Finally append ~/.cabal/bin/ to your PATH.
