Using ghcmod-vim with cabal repl #44

Closed mpickering closed 10 years ago

mpickering commented 10 years ago

Hey guys,

Is there a way to easily do this? Literature suggests that in emacs you simply use the command

setq haskell-program-name "cabal repl"

I can't figure anything similar for vim.

I would also love to know this... seconded.

eagletmt commented 10 years ago

What do you want to do with cabal repl?

haskell-program-name is a custom variable of haskell-mode and it specifies the interpreter which runs under Emacs, right? ghcmod-vim doesn't have a feature to interact with Haskell interpreter. It only uses ghc-mod command.

jatcwang commented 10 years ago

cabal repl respects the new cabal sandbox configurations, while ghci doesn't (I believe).

I'd like to know whether this is possible too.

eagletmt commented 10 years ago

I know what cabal repl does. I'd like to figure out what is the issue with ghcmod-vim... ghcmod-vim doesn't use ghci or any other Haskell interpreters at all.

The question is: when ghc-mod is integrated into emacs you are able to change this behavior, how are you able to do the same from inside vim? It isn't a ghcmod-vim issue per se but I felt like this was the most suitable place to ask. The issue is that when using ghc-mod with vim at the moment and you're developing a library, ghc-mod complains about not being able to find the library because it doesn't look in the sandbox.

Opening a REPL within Emacs is NOT a feature of ghc-mod. It's a feature of haskell-mode. haskell-program-name is a custom variable of haskell-mode. Elisp maintained in ghc-mod doesn't use any Haskell interpreters. I won't add REPL feature to ghcmod-vim because ghc-mod doesn't have REPL feature. ghcmod-vim is a plugin for ghc-mod.

That is the real issue! :v: It has no relation with cabal repl. ghc-mod should automatically discover the sandbox and look in it. Are you using the latest ghcmod-vim and ghc-mod? ghc-mod < 4.0.0 has sandbox problem with project which has sandbox but doesn't have cabal file.

It's been working fine for me. I have installed packages that is sandbox-only, and ghc-mod has not complained about it, and can deduce the types correctly etc.

Probably updating to the latest ghc-mod will help.
