Syntax highlighting works for a bunch of languages including Haskell, using GeSHi and Jason Dagit's Haskell file, somewhat modified.
Block formatting with <haskell>
To highlight syntax of a block of Haskell, enclose it in <haskell>
...</haskell>
. This uses the <pre>
element. For instance:
{-
My program
-}
import Prelude
foo :: (Monad m) => m (Int,Int)
foo = (x-2,x - 1) where
x = 3
-- The main function
main :: IO ()
main = do
a <- foo
putStr ("And the answer is: " ++(show (fst a))++"\n")
Inline formatting with <hask>
To highlight syntax of inline Haskell snippets, enclose the span in <hask>
...</hask>
. This uses the <code>
element, which is inline. For instance: import Prelude
.
Inline highlighting is a bit of a hack at the moment, and may be buggy.
Styles
For Haskell (only) I have deliberately removed all formatting apart from foreground colour, and those I have tried to keep dark so as not to be visually distracting.
This is what I am trying to achieve:
- comments: grey
- keywords (including symbols): blue
- value literals: dark green
- known value identifiers (including symbols): green
- known type identifiers: red
- known classes: purple
- known modules: brown
I also indent the entire block by 2em. See MediaWiki:Common.css.

Other languages
This works for certain other languages too. For lisp, for instance, use <pre-lisp>
...</pre-lisp>
to format a block of lisp, and <code-lisp>
...</code-lisp>
to format text inline. <haskell>
is the same as <pre-haskell>
and <hask>
is the same as <code-haskell>
.
