A completion plugin for Haskell, using ghc-mod

Completion only works if ghc-mod is installed into the sandbox. #26

Closed seanparsons closed 10 years ago

seanparsons commented 10 years ago

I've found others recommending installing ghc-mod into the sandbox and when I did that previously it worked. However I'm trying to have a clean build set up where all the command line tools are in ~/.cabal/bin and no other dependencies are installed.

This seems to result in the code completion just showing me things that are already present inside the file, which seems wrong full stop.

For reference these two files make up my .vimrc: https://github.com/seanparsons/dotfiles/blob/master/vimrc-stage1 https://github.com/seanparsons/dotfiles/blob/master/vimrc-stage2

eagletmt commented 10 years ago

I've added a diagnostics command. Please checkout the latest revision https://github.com/eagletmt/neco-ghc/commit/37434dfc33a47a2d21518fbfa24ad43a7f6806e0. Then please execute :NecoGhcDiagnostics in the buffer opening a Haskell file which you have trouble with and show me the output.

Current filetype: haskell ghc-mod is executable: 1 omnifunc: neocomplete.vim: 2 neocomplcache.vim: 0 YouCompleteMe: 0 vimproc.vim: 701 ghc-mod: 3.1.6 Imported modules: Prelude Number of symbols in Prelude: 0

eagletmt commented 10 years ago

Thanks. The ghc-mod browse command outputs nothing or weird result.

Could you run ghc-mod list and ghc-mod browse Prelude in the directory where the Haskell file exists?

Is there a sensible way of getting the plugin to log the commands it's sending along with their outputs?

seanparsons commented 10 years ago

Is it these diagnostics values that indicate something is wrong: Imported modules: Prelude Number of symbols in Prelude: 0

I've only just mentally clicked looking at this again that those are an indicator of it being wrong.

seanparsons commented 10 years ago

I fiddled around and found that some calls to ghc-mod were apparently blowing up and the reason for that appears to be this line: https://github.com/eagletmt/neco-ghc/blob/master/autoload/necoghc.vim#L240 Passing "package ghc" to ghc through ghc-mod was completely exploding and I believe because those are system packages and not installed in the sandbox:

sean@Tower:~/workspace/argonaut-hs$ ghc-mod -g -package -g ghc list
Dummy:0:0:Error:<command line>: cannot satisfy -package ghc: 
    ghc-7.6.3-494fae4c96de6ac955b246ac79054c22 is unusable due to missing or recursive dependencies:

I've tried this locally and it appears to be working so far.

Thank you for finding the cause! :bow:

But the root cause is still unclear. Why does it happen? I think your package db is broken. Does ghc-pkg check say any errors? If you're working in a sandbox, does cabal sandbox hc-pkg check say any errors?

The reason why I added -g ghc is the ghc package is hidden by default. When I'm writing codes using GHC API without cabal file, passing -g ghc is needed. Adding -g ghc is supposed to have nothing to do with non- GHC API users.

Neither of those commands give me any errors and I would be surprised if my package db is broken just because when experimenting with this my install script nukes everything in my user folder. The only thing that I do which is slightly odd is that I install a few command line tools and then clear out all the libraries using this little snippet: https://github.com/seanparsons/dotfiles/blob/master/install.scala#L135-L141 Which just unregisters them and deletes their folders which is all that cabal-uninstall does IIRC.

I couldn't reproduce it... :confused: But I will accept your pull request removing -g ghc. Automatically adding -g ghc would help fewer people.

Btw, It's also unclear why my added diagnostics doesn't report errors. It has a check to see if the output countains 'Dummy:0:0:Error:'.

@seanparsons FYI: I remembered that ghc-mod 3.1.6 includes changes about package-id. https://github.com/kazu-yamamoto/ghc-mod/pull/179 If you cannot reproduce the same error with ghc-mod 3.1.5, the error might be related to it.
