Hi,
I have been using ghc-mod for a long time and I can’t give it up now, but I have
an annoying problem.
When I have a cabal file with a library and an executable depending on the
library (for example here
https://github.com/bitonic/kant/blob/master/kant.cabal), ghc-mod is not happy,
Hi Francesco,
To keep ghc-mod happy, you also have to keep ghci happy. What you
probably need is a .ghci file in the directory with a :set -isrc line
in it. You may also need to add other stuff to .ghci such as language
extensions and whatever else is needed to load your project with ghci.

It finally occurred to me how to get most of what I want, at least from a
functional perspective.Here's a sample GADT, with four categories of
constructor:
data Foo :: Bool - Bool - Bool - Bool - * where
A :: Foo True b c d
B :: Foo True b c d
C :: Foo a True c d
D :: Foo a

And I still get the mentioned error. Did you take any other measures to make
things work?

If so, I will think how to treat this kind problem.
The ‘kant’ package is the package I’m developing and using ghc-mod on. It
includes both a library and an executable.

Yes. I understand it.
It includes both a library and an executable. The executable target
has ‘kant’ as a dependency.
What I asked is whether or not the kant library is installed by
cabal.

Well installing it has the big problem that each time I make a
change to the interface I have to manually re-install, and this
happens often since I’m in an early stage...
I'm not saying that you should install it. But I just want to know
your situation.
Right, but this is surely doable

Hello, I'm trying to understand cabal-dev, and I seem to be missing some
basic point, because I can't get dependencies between projects working
properly.
I have two projects, let's call them P1 and P2. P2 depends on P1, as
indicated by its cabal file build-depends field.
I run cabal-dev add-source
The proposed changes are described here:

You need to call cabal-dev add-source on P1 again to copy over the sdist,
then do a cabal-dev install.

That's exactly what I'm doing, and I was exactly following these notes, but
it doesn't work. This google+ post and the answers to it (

at least one solution that seems to work: you need to unregister the

Johan, thanks, that brings me to a point that I wanted to raise. I'm
playing with cabal-dev because users have asked me to add support for it in
EclipseFP (so projects could have their own sandbox and have dependencies
between projects without polluting the main package databases). It is worth

Hi list,
I wrote a script that reads matrix elements from standard input, parses the
input using a regular expression, and then bins the matrix elements by
magnitude. I wrote the same script in python (just to be sure :) ) and find
that the python version vastly outperforms the Haskell script.

Yes, a histogram. The binning code is really a little awkward. I haven't

I don't know about xml-conduit but I know that such thing is possible in

Hello,
In the QuickCheck library, there is a type-class called CoArbitrary. It
is defined like so:
class CoArbitrary a where
coarbitrary :: a - Gen b - Gen b -- Gen is a monad
Its purpose is to allow generation of functions. In other words, for
taking Gen x - Gen (a - x), which could be done
