This Mephisto plugin is based on a Typo plugin by Tom Moertel.
To use it, you need to have HsColour in your path. You can install it using:
sudo cabal install --global HsColour
Of course, this assumes that you already have GHC and Cabal installed on your system. This can frankly be a bit tricky on shared web servers.
From inside your copy of Mephisto, run:
script/plugin install git://github.com/emk/filtered_column_haskell_macro.git
Use <macro:haskell> to wrap your code.
<macro:haskell> addTwo :: Num a => a -> a -> a addTwo x y = x + y </macro:haskell>
You will need to add some syntax-coloring rules to main.css. Here’s a minimal set of rules adapted from Tom Moertel’s original blog post.
.haskell_code .keyglyph {color: #b8860b;}
.haskell_code .keyword {color: #a020f0;}
.haskell_code .comment,
.haskell_code .comment a {color: #b22222;}
.haskell_code .str,
.haskell_code .chr {color: #bc8f8f;}
.haskell_code .conid {color: #228b22;}
