Updates for changes in GHC API. Fixes #24.

[schell]

hdevtools now compiles for me on ghc7.7.

[schell]

With this new build I'm sometimes getting "Could not find module x" errors, where x is my own module defined in my project. This problem goes away if I visit the corresponding file in vim. Is this normal? Could my changes have introduced this bug? I'll admit I'm not familiar with the GHC API so my updates could very well be naive at best. They should be vetted.

[bitc]

This is not normal, but it may be a change in GHC API not related to your changes.

I plan on waiting for GHC 7.8 to be released (which should happen soon), before looking into this

[schell]

It seems that it had to do with the directory from which I started vim and subsequently, which directory I'm currently looking at in NerdTree. If I start from the directory that contains my Main.hs then everything works fine, so maybe it was just that hdevtools didn't know where my Main.hs was living.

[schell]

There were more changes to the GHC API pertaining to Pretty.showDocWith, which changed to Pretty.showDoc. I rebased, squashed and pushed a fix.

[schell]

showDoc now takes a mode and an Int, but the documentation doesn't say what the Int is for - so I just used 1 as a placeholder.

+1, this patch allows building hdevtools using GHC 7.8.

[MaxDaten]

ghc-7.8.1 is now released, and this patch is still compatible :)
any chance to update put a new version on hackage, thx :)

Also, I've merged these changes with those from @maximkulkin that give cabal support. It seems to be working well for me in vim.

would love to see this land

[bitc]

Thanks for this! I'll try to find some time in the next few days to merge and update hackage.

One tiny nitpick: Is "707" the proper ifdef guard as you are doing, or should it be 708? What does the community think?

[dmalikov]

@bitc it will be great to have new 7.8-compatible package

[schell]

@bitc - the reason I used 707 is because at the time 7.8 wasn't officially out yet. I was using GHC HEAD, which was 7.7. So 707 is valid, but feel free to change it if you think it's confusing! :)

[reem]

This just compiled cleanly for me on Mavericks with 7.8.2. Thanks a ton.

[darthdeus]

This works for me too on Mavericks 10.9.3 and GHC 7.8.2. Awesome job!

Status?

[Procee]

When will this be merged in?

For those using Nix, include this patch until a new version is out:
edit nixpkgs/pkgs/development/tools/haskell/hdevtools/default.nix to this:

{ cabal, cmdargs, ghcPaths, network, syb, time, fetchpatch }: cabal.mkDerivation (self: { pname = "hdevtools"; version = "0.1.0.5"; sha256 = "1a218m817q35f52fv6mn28sfv136i6fm2mzgdidpm24pc0585gl7"; isLibrary = false; isExecutable = true; patches = [ (fetchpatch { url = "https://github.com/bitc/hdevtools/pull/28.patch"; sha256 = "1rlv5zskg4ns9ba791x72gycxrr52lhy8x164q38gpq600gh5n40"; }) ]; buildDepends = [ cmdargs ghcPaths network syb time ]; meta = { homepage = "https://github.com/bitc/hdevtools/"; description = "Persistent GHC powered background server for FAST haskell development tools"; license = self.stdenv.lib.licenses.mit; platforms = self.ghc.meta.platforms; }; })

Bump

[mitchellwrosen]

@bitc Are you alive? Last we heard you would try to merge this within a "few days", Apr. 24. Would love to get a 7.8-compatible version on Hackage so I don't have to build from source.

[schell]

This patch no longer compiles as of GHC 7.8.3 so I'm closing and have submitted a new one (#33) that includes cabal support by @maximkulkin.
