Syntax highlighting works for a bunch of languages including Haskell, using GeSHi and Jason Dagit's Haskell file, somewhat modified.

Contents

1 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")

2 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.

3 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: dark grey
  • keywords (including symbols): blue
  • value literals: dark blue
  • known value identifiers (including symbols): dark green
  • known type identifiers: dark red
  • known classes: pink
  • known modules: brown

4 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> the same as <pre-haskell> and <hask> the same as <code-haskell>.
