ghc-mod and GHC 8.2.x #282

Closed jship closed 6 years ago

jship commented 6 years ago

ghc-mod on 8.2.x has been broken for a while, but here recently looks like there is a workaround for getting it installed using cabal-helper. Some progress has been made too on adding official support.

I could see this as pretty frustrating for new users of haskell-vim-now if the ghc-mod install blows up and the install fails. A few options:

  1. Do some special casing on how we install ghc-mod. This could be a maintenance/support chore.
  2. Try to install ghc-mod normally, but if it fails, don't stop the installer. Instead provide a link to instructions on troubleshooting the install of it.
  3. Don't bother with installing ghc-mod as part of haskell-vim-now's install. Instead just provide instructions.
jship commented 6 years ago

I haven't used ghc-mod in a while. I'd be inclined to remove ghc-mod from haskell-vim-now since it is tricky to get right (and in this case, build) with the current versions of GHC. That would be a fourth option.

begriffs commented 6 years ago

Hmm, for me doing identifier completions and querying types under the cursor is really important.

How about in the short term we go with your option 2? I'm also curious whether viable ghc-mod replacements exist.

bidhan-a commented 6 years ago

As a new user, this has been very frustrating. I had high hopes for this when I first came across it. Wish there was at least some kind of workaround mentioned in the docs because it is evident a lot of users are having this issue.

jship commented 6 years ago

Hi @bidhan-a, I am a bit strapped for OSS time at the moment. Would you be interested in submitting a PR for this? I would be happy to help guide you to the spots in the code we could change.

As a start, in setup_haskell.hs, we would need the stackInstall function to not kill the whole install run on failure. This could be passed in as a flag to stackInstall, because we probably still want the install run to die on other things we stackInstall, but for the ghc-mod install, we'd like to keep the installer going on failure.

bidhan-a commented 6 years ago

Hi @jship ,

I'd be glad to help out in any way I can since I'm really looking forward to making it work on my machine.

As per your suggestion, I have modified the stackInstall function to take a flag as an argument. Please review the code here if possible and let me know if I need to add anything else.

I have tested the modified script and the installer successfully moves past that point, but unfortunately it exits with another error after a while. The error looks similar to the one described in 278 and 270. Here's the complete log if it helps:

Any way I can get around this one? I have the latest version of Stack by the way.

Nice, @bidhan-a! I have a feeling getting #276 merged will get you past this error. I'll merge that PR in.

As far things to add, we'll probably want to let the user know about a link or two they can go to so they can manually install ghc-mod if our attempted install fails.

Hi @jship ,

Still no luck. I'm getting a similar error even after merging #276 .

ghc-8.2.2 cannot be used for these packages:

   - dependencies requires >=4.9 && <4.10

This may be resolved by:
   - Using '--omit-packages to exclude mismatching package(s).
   - Using '--resolver' to specify a matching snapshot/resolver

It seems the problem is with the "hscope" library this time.

On a side note, I've included the following URL as a reference for the user in case they want to manually install ghc-mod.

Thanks!

jship commented 6 years ago

Looks like the upper bound on base is too restrictive in our auto-generated .cabal file for the helper binaries. Mind changing this line's 4.10 upper bound to be 4.11?

GHC 8.2.2's bundled base package is version 4.10.1.0.

*** Failed to arrive at a workable build plan.

Solver could not resolve package dependencies.
You can try the following:
    - Use '--omit-packages to exclude conflicting package(s).
    - Tweak the generated stack.yaml and then run 'stack solver':
        - Add any missing remote packages.
        - Add extra dependencies to guide solver.
    - Update external packages with 'stack update' and try again.

Hmm, what version of stack do you have? Can do a stack --version.

If it winds up that you have the latest stack, we may be able to get past this by changing this line to:

stackInstall "lts-7.24" "cabal-install" True

This would ensure we are not doing the dependency solving with cabal 2, which apparently stack is having some trouble with.

I recommend first upgrading stack if needed and trying again before changing that line.

bidhan-a commented 6 years ago

I have the latest version of Stack (1.6.3) on my machine. I'll try the other option and let you know how it goes.

bidhan-a commented 6 years ago

Unfortunately, I'm getting the same error, except for the "Warning: Installed version of cabal-install (2.0.0.1) is newer than stack has been tested with. If you run into difficulties, consider downgrading." part.

jship commented 6 years ago

@bidhan-a: So you are no longer seeing Warning: Installed version of cabal-install (2.0.0.1) is newer than stack has been tested with. If you run into difficulties, consider downgrading.? I want to be sure that stack is using the correct cabal binary.

Can you do a:

cabal --version

Based on #270 and #272, I'm wondering if there is some weirdness in your environment. Can you also do a:

cat ~/.stack/global-project/stack.yaml

Thank you for being so helpful on this! 👍

bidhan-a commented 6 years ago

HI @jship ,

No problem at all.

That's correct. I'm no longer seeing that particular warning.

Here are the results:

cabal --version
cabal-install version 1.24.0.2
compiled using version 1.24.2.0 of the Cabal library
cat ~/.stack/global-project/stack.yaml
# This is the implicit global project's config file, which is only used when
# 'stack' is run outside of a real project.  Settings here do _not_ act as
# defaults for all projects.  To change stack's default settings, edit
# '/home/bidhan/.stack/config.yaml' instead.
#
# For more information about stack's configuration, see
# http://docs.haskellstack.org/en/stable/yaml_configuration/
#
packages: []
resolver: lts-10.4

Thanks.

jship commented 6 years ago

Hmm, the plot thickens then! I feel like the next steps would be to try it on a clean VM. Are you doing any cleanup in between runs? If you want, you can try doing the install on a clean VM.

A "worst case" kind of workaround would be to explicitly install the helper binaries using a known compatible resolver until we can figure out something better. I think lts-7.24 was the last known one to work. In this case, we wouldn't even use stack to do the dep solving. We'd just write out a stack.yaml with a hard-coded LTS or something. We'll have to think about it.

bidhan-a commented 6 years ago

Hi @jship ,

Yes, I've done cleanups between runs. I also tested it on another Ubuntu system and I got the same result. I have tested it on a VM using both Ubuntu and Fedora distros, but to no avail.

Would you be able to point me in the right direction regarding how to get the workaround to work? I guess the "worst case" scenario will be good enough for people like me who just want to get this working, until there's a better solution.

Thanks

jship commented 6 years ago

@bidhan-a, I merged your changes into my fork and was able to get the installer working with this additional (somewhat hacky) commit: https://github.com/jship/haskell-vim-now/commit/c05e841b9a3acc6eeb0fbd2d05411e19e7713db4

Will open a PR with more detail.

bidhan-a commented 6 years ago

@jship , thanks a lot! The installer worked on my machine too. :sweat_smile:

One extra thing that I did; since we're using lts-7.24 for the time being anyway, I used it to install ghc-mod as well.

Thanks again.

jship commented 6 years ago

That's great news, @bidhan-a! 👍 Thanks for re-testing.

I'll go ahead and merge that PR and close out this issue.
