Stack integration still requires `stack exec atom` #119

Closed elldritch closed 8 years ago

elldritch commented 8 years ago

Running haskell-ghc-mod 1.6.6, I still need to invoke Atom via stack exec atom in order to use ghc-mod check or ghc-mod type. Otherwise, ghc-mod fails with <some package>-<version>-<hash> is unusable due to missing or recursive dependencies: <packages here> (use -v for more information). I'm guessing this is because Stack does some extra magic behind the scenes that allows ghc-mod to read its packages.

lierdakil commented 8 years ago

This should not be the case. My guess is you need to run stack build before ghc-mod can pick up your project. Either that, or you have multiple versions of ghc-mod installed and those conflict with each other.

elldritch commented 8 years ago

Running stack build doesn't help. Opening up the developer console shows that ghc-mod fails because a package's dependencies cannot be resolved due to recursive or missing dependencies. I'm guessing that ghc-mod is somehow not detecting that I'm using Stack.

lierdakil commented 8 years ago

Okay. Here are some troubleshooting suggestions:

  1. Make sure you don't have dist/setup-config file in project directory (this will make ghc-mod default to cabal). Make sure you have stack.yaml in your project directory (obviously)
  2. Run ghc-mod in your project directory directly. You can do something like ghc-mod check main-file.hs for testing purposes. Read output.
  3. Testing for any rouge ghc-mod installations, if you're on POSIX (Linux or Mac), run which ghc-mod and stack exec which ghc-mod in your project directory. If you're on Windows, run where ghc-mod and stack exec where ghc-mod in your project directory. Compare output.

Please let me know if you figure something out.

Using ghc-mod check <file> fails for me with the dependency error, but stack exec ghc-mod check <file> succeeds with no output. Ghc-mod is installed using Stack (which ghc-mod evaluates to /home/leo/.local/bin/ghc-mod).

stack exec which ghc-mod gives a different output (/home/leo/.stack/snapshots/x86_64-linux/lts-5.4/7.10.3/bin/ghc-mod), but I installed ghc-mod with stack install ghc-mod globally using the lts-5.4 resolver and the binary copied to .local/bin is the same one in the lts-5.4 snapshot. Are there any environmental variables which stack exec sets that aren't being set when Atom is invoked outside of Stack?

DanielG commented 8 years ago

Are you absolutely positive those two executable are identical? (I'd compare their hashes or something) Anyways ghc-mod debug and stack exec ghc-mod debug should help spotting the difference either way so please post both.

elldritch commented 8 years ago

Yes, they have identical MD5 hashes. When I diff the debug commands, it seems stack exec ghc-mod debug is prepending <path to project>/.stack-work/install/x86_64-linux/lts-5.4/7.10.3/bin and /home/leo/.stack/snapshots/x86_64-linux/lts-5.4/7.10.3/bin to seBinPath in the StackEnv record of StackProject.

The snapshots folder only has the executable of my project and the snapshots folder contains ghc-mod and ghc-modi (which still have the same hash as the result of which ghc-mod and which ghc-modi).

DanielG commented 8 years ago

Can you post the complete output of the two commands too please.

elldritch commented 8 years ago

In order to avoid getting the error cabal: At least the following dependencies are missing: ..., I'm configuring using cabal configure --package-db=clear --package-db=global --package-db=$(stack path --snapshot-pkg-db) --package-db=$(stack path --local-pkg-db). Is this part of the problem?

Interesting, I can't find a single difference in those two logs. However just as I suspected ghc-mod is not recognizing your project to be a stack project. See the Project: CabalProject field in the output, that should say StackProject {...}.

Oh I just realized. Of course the configure command is interfering since that forces ghc-mod into cabal project mode since it creates dist/setup-config. So you're getting that At least the following dependencies are missing error even just with the debug command?

elldritch commented 8 years ago

No, the debug command works fine. Interestingly, rm -r dist causes stack exec ghc-mod check <file> to work fine, but ghc-mod check <file> fails with <package> is unusable due to missing or recursive dependencies.

After running rm -r dist:

stack exec atom . still works (ghc-mod will show me type info) and atom . still doesn't work (ghc-mod shows me an error occurred with the backend).

Alright we're getting somewhere. You're getting Project: StackProject ... in both cases now. So my guess is there is something going wrong in cabal-helper or something. I'll need ghc-pkg list, cabal --version and ghc-mod check -vvv <whatever> oh and you haven't mentioned the version of ghc-mod yet I think so ghc-mod --version too. (In case it's less than 5.5.0.0 you might have to use -v7 instead of -vvv we changed that some time ago.)

I am having the exact same problem and here is the info you requested.

Do please also run ghc-mod check -v 7 Main.hs (or not Main.hs, but other file, you get the idea)

DanielG commented 8 years ago

@callmeyesh Also ghc-mod debug in both cases, same as above.

callmeyesh commented 8 years ago

I ran ghc-mod check app/Main.hs -v and it didn't throw any output.

@callmeyesh oops, sorry, my bad. ghc-mod --verbose 7 check your-file.hs. Just -v doesn't show everything.

DanielG commented 8 years ago

@callmeyesh You should be getting some error at least, no? If not then what's the problem anyways :p Also please do it both with and without stack exec at the front. The whole point of this exercise is to spot the difference that invoking ghc-mod via stack exec makes vs. a normal run.

Sorry about that guys. @DanielG There is no error being thrown from the command line, I just created this test project using

stack new helloworld new-template

Then added the project folder into atom and I get the following error

In the second case you have to make stack stop parsing commandline arguments using --: stack exec -- ghc-mod --verbose 7 check app/Main.hs.

@lierdakil any idea what atom could do differently then? I mean it probably uses legacy-interactive rather than the single shot commands and that difference does often cause problems but I'm hoping it's not that since it's a complete nightmare to test that by hand.

That's a completely different issue though... @callmeyesh, does disabling Enable GHC-Modi option in haskell-ghc-mod settings make any difference?

callmeyesh commented 8 years ago

@ilikebits No it doesn't help.

lierdakil commented 8 years ago

Okay. So from what I can gather, when run from Atom, ghc-mod tries to run cabal for some reason: ghc-mod: cabal: readCreateProcess: runInteractiveProcess: exec: does not exist (No such file or directory). It shouldn't do that on stack projects though (and it indeed does not in my tests).

Moreover, this happens in Atom, but not in command line. Only reason for that I can see is when run from Atom, ghc-mod can't find stack executable.

@callmeyesh, where is your stack executable, by the way? Is it on PATH?

callmeyesh commented 8 years ago

@lierdakil Yes

echo $PATH

callmeyesh commented 8 years ago

In the settings, for Additional Path Directories I have added the following paths /usr/local/bin/ghc, /Users/yvenkatesh/.local/bin/cabal

And in the Ghc Mod Path /Users/yvenkatesh/.local/bin/ghc-mod

lierdakil commented 8 years ago

@callmeyesh, FYI, you misspell my handle... so it pings the wrong person.

I don't see stack in /Users/yvenkatesh/.local/bin/. Is it in /usr/local/bin/?

Also, do change 'Additional Path Directories' to /usr/local/bin, /Users/yvenkatesh/.local/bin -- it's directories, not executables... probably should change wording in places...

callmeyesh commented 8 years ago

@lierdakil Ah sorry about misspelling your handle. I installed stack using homebrew and its in /usr/local/bin.

I added /usr/local/bin to the Additional Path Directories and everything works fine now :+1:.

callmeyesh commented 8 years ago

Thanks for helping out @lierdakil & @DanielG. May be the README should be updated, so people who have installed stack using homebrew wont encounter this error.

lierdakil commented 8 years ago

Glad to hear it's working. I'll try to think of a better way of describing necessary configuration...

lierdakil commented 8 years ago

@ilikebits, could you check if this solution works for you? I think it might.

@callmeyesh, sorry for late reply. Health issues. Anyway, it seems like you try to run ghc-mod on a project using different GHC version than ghc-mod was built with. See https://github.com/atom-haskell/haskell-ghc-mod/wiki/Using-with-stack#maintain-a-separate-ghc-mod-installation-for-each-stack-resolver for more information on that.

lierdakil commented 8 years ago

Hopefully this should be resolved by now. If not, open new issue.
