Yes, it works better. Thanks for fixing my dumbness. But then, why is it documented the other way ? Regards, Arnaud On Thu, Aug 25, 2011 at 4:30 PM, Roel van Dijk wrote:

Does it help if you format it like this:

-- |Apply a given function over all elements of a list and select one of the -- results. selector :: (Arbitrary b) => [a] -- ^ Elements to select from -> (a -> b) -- ^ Constructor to apply to selected element -> Gen b selector list ctor = oneof (map (return . ctor) list)

So placing the => and -> before the lines instead of after them?

Hello, while trying to generate Haddock documentation (Haddock version 2.9.2, (c) Simon Marlow 2006), it chokes on the following fragment

-- |Apply a given function over all elements of a list and select one of

-- results. selector :: (Arbitrary b) => [a] -> -- ^ Elements to select from (a -> b) -> -- ^ Constructor to apply to selected element Gen b selector list ctor = oneof (map (return . ctor) list)

with the following error message:

' parse error on input `-- ^ Elements to select from

I am puzzled as this is exactly how arguments are supposed to be documented, according to http://www.haskell.org/haddock/doc/html/ch03s02.html#id565220

Any clues ?

OK. Time to go to bed... Apologies for the noise. Arnaud On Thu, Aug 25, 2011 at 4:50 PM, Ozgur Akgun wrote:

It isn't, as far as I can see. Are we both looking at the same place, namely section 3.2.3?
