Strange.

/tmp $ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.6.3
/tmp $ cat Test.hs
module Main (main, y, x) where

/tmp $ haddock --version
Haddock version 2.13.2, (c) Simon Marlow 2006

/tmp $ haddock Test.hs --html
Haddock coverage:

Well, it's a high possibility that my Haddock version isn't the stock
one that comes with 7.6.3. In any case, I'm glad that you say it's
fixed in HEAD. Thanks for checking.

Uhm, actually there is, with 7.6.3.

  % cat haddock.hs
  -- Main

  (x, y, z) = (1, 2, 3)

It's great that it's fixed in HEAD.

I would like to add onto this that we can actually get the Haddock
documentation generated for ‘y’ by exporting it in the module and then
we can easily link to it, you're simply not getting the Haddock
comment along.

In the future, please try with more recent version of GHC.

This is no longer a parse error with HEAD or 7.6.3. Instead, given

 -- | 'y' and 'x' are here
 (x, y) = (1, 2)

you get documentation generated for ‘x’ and Haddock doesn't seem to
have any idea where to link ‘y’ (but it does know it's in scope &c). I
think this behaviour is understandable considering that ‘x’ is the
first ‘function’ after Haddock comments so the comment belongs to ’x’.
If you want a different behaviour, please file an enhancement request
against a recent version to have it considered.

I don't understand your concern over privacy in this case: you're
getting a lot more exposure just posting on café than you ever would
by posting directly on the low-traffic Haddock Trac. You're free to
register with a temporary e-mail.

Hi,

I cannot find a similar ticket, so it seems that no one has filed this
issue before.  As a general comment, I think this issue is a good
example that perhaps docstrings should go in the AST.

In any case, I would ask someone with a trac account in Haddock to
submit this ticket for me.  I apologize for the inconvenience, but,
for privacy concerns, I don't want an account in Haddock trac and it
does not seem possible to submit a ticket without first creating one.

Thanks,
Jose

In any case, it shouldn't fail with a parse error, since this is valid
Haskell.

Please file a ticket at http://trac.haskell.org/haddock (but first see
if it hasn't been reported before).

[Haskell-cafe] Haddock multiple definitions

2013-08-15 Thread jabolopes
Hi,

I am using

  GHC: 6.12.1
  Haddock: 2.6.0

and the following does not work with Haddock (GHC is fine!):

  -- Main

  -- | Blah blah blah
  (x, y, z) = (1, 2, 3)

$ haddock ...
/tmp/Main.hs:2:0: parse error on input `('


Is this a bug? Or it's just not part of Haddock?


This seems like an interesting feature to document several definitions
together, for example, error codes:

-- | Syscall error codes for blah...
--
-- errA when blah
-- ...
(errA, errB, errC) = ...

Cheers,
Jose
