Hello,
I have a midsize program, and would like to simplify the module interfaces
for my own sanity. I know there are tools to check for extraneous imports,
but is there something similar for exports? For instance, if module A

Hi Don,
This doesn't tell me what is extraneous in the exports. For instance
If I have two modules A and Main
module A (f, g) where
f :: a - a
f = id
g :: a - a
g = id
module Main (main) where
import qualified A
main :: IO ()
main = do
let a = A.f 7

I'd like
Say I have the following module:

When I use A with the following imports, I don't expect this to work,
but it does:

Hi,
Is there a way to make haddock not generate instance documentation

Is there a way to get the source documentation from cabal haddock

Right now the unicode from my comments and source programs are being
mangled. I tried the --haddock-option=--use-unicode option, but it
seems to only work
Hello,
I'm having trouble setting breakpoints from ghci. I load the files

Hi,
I'm trying to compile some code using Cabal. One of the files has a CPP
directive
#include undefined.h
The file undefined.h is in the same directory as the file with the
directive.
If I use the full path name, cabal can compile it. However, if I use the
relative path,
it complains about

I have a program that does a lot of unicode manipulation. I'd like to use

However, since hslogger uses System.IO.putX, the unicode comes out mangled.
I hacked the source to

I'm getting different behavior in ghci and ghc with the identifier ∀. In

In ghci, I get an error this way

Hi Daniel,
Would you try putting that in a file and loading it in ghci? Your

I'm having trouble understanding the following behavior. The following
program compiles:
{-# OPTIONS_GHC -XMultiParamTypeClasses -XFlexibleContexts #-}

class Has α s where
has :: s - (α, s)
project :: (MonadState s m, Has α s) = m α
project = do (α, s) - gets has
Ah, I see. Thanks very much. For some reason I figured the second type would
be resolved to Int, but now I see that is totally wrong.
Best,
