Not handling cabal-dev projects?

[jwiegley]

I have a large project that I build with cabal-dev. "hdevtools check" claims that a module installed into my cabal-dev isn't available, while "ghc-mod check" works correctly.

I personally use hsenv, rather than cabal-dev, which works great with hdevtools. (And I personally find it more powerful and easier to use, not requiring learning any new commands).

Since I'm not that familiar with cabal-dev, I'm not sure what is necessary to add support for it. I think I remember reading that ghc-mod had to specifically add support for it.

Anyway, cabal-dev support is definitely something that would be good to have in hdevtools.

[jwiegley]

I would love to use hsenv, but I've never been able to get it to work for any of the meaningful projects I work on on my Mac, while cabal-dev has never given me any problems so far.

[jwiegley]

I've switched to using hsenv, but am having the exact same problem. It can't find any of my installed packages, while GHC can in the same environment.

when i was still using cabal-dev (i'm using cabal sandboxes now), the following vim snippet worked for me. it should be easy to adopt to your situation/editor. having said that, native integration would be great as well. it might be nice to teach hdevtools to read the cabal file...

function! FindCabalDevRoot()
    return finddir('cabal-dev', './;')
endfunction

function! FindCabalDevRootPackageConf()
    return glob(FindCabalDevRoot().'/packages-*.conf')
endfunction

let g:hdevtools_options = '-g-ilib -g-isrc -g-i. -g-Wall -g-XOverloadedStrings -g-package-conf='.FindCabalDevRootPackageConf()

Use the new cabal sandbox feature. This issue should be able to be deprecated.

[jwiegley]

Agreed, cabal sandbox has been working great, just need to convert over our tooling to use it.

Looks like hdevtools explicitly searches for *.hs files even when only *.hi are installed:

[hsenv]➜  geometroid git:(master) ✗ hdevtools check -g '-v' Fighting.hs
...
<no location info>: *** Chasing dependencies:
<no location info>: Chasing modules from: *Fighting.hs
Fighting.hs:9:18:
    Could not find module `Data.Random.Extras'
    Perhaps you meant

      Data.Random.Source (from random-source-0.3.0.6)
    Locations searched:
      Data/Random/Extras.hs
      Data/Random/Extras.lhs

@constantius9 Is this related to this issue #6 "Not handling cabal-dev projects?"? If not, could you please open a new issue for this? Thanks!

[mkpankov]

@bitc Yes. More like "not handling hsenv properly", but since it all was discussed here, I posted it to this issue.

[tomberek]

Having a similar issue. *.hi is not seen.

Is there any work around to tell hdevtools to check for .hi files?
