Hi all,

If I have the following data type:

data Expr = Num Int | Expr :+: Expr | Expr :-: Expr

Haddock handles the infix constructors, and generates a very nice output (html in this case) However when I try to reference to one of the infix constructors in the markup of other functions it fails to hyperlink.

-- | If the input is 'Num' does magic, if it is ':+:' does even more magic! someFunc :: Expr -> Expr

In the output of this markup, the 'Num' is hyperlinked but the ':+:' is not. Is there a different syntax for infix constructors (and for infix functions presumably) or does haddock simple lack this feature?

Infix functions work fine (try referring to e.g. '&&' in the haddock comment), but infix constructors apparently not.

Yes, I actually fixed this a few weeks ago in Haddock's lexer. Colon was just not included in the character set for identifiers. David

My guess: $ cabal install haddock-2.7.2

No, it's not yet in there :(

Yes, I should make a new release. In the meantime, you could try darcs get http://code.haskell.org/haddock David

I shouldn't have choosen Num for the constructor name, it led to confusions apparently. You can replace tha Num with anything you want, doesn't change the situation. I mean, it's not the problematic part. Is there any news about the fix in the lexer? When can we use it? On 27 April 2010 00:52, Ivan Miljenovic wrote:

I would hazard a guess that the Num hyperlink points to the Num typeclass in the Prelude rather than your Num constructor. As for your infix constructor, I have no idea.
