Can't find interface-file declaration when loading a TemplateHaskell-enabled module #149

maoe · 2020-06-06T01:58:49Z

Current master (2310e10) of HLS fails to load threadscope like this:

Hi, it is a shoot in the dark but maybe cleaning the cache of ghcide and hie-bios. where they save hie files, could help: they are in $XDG_CACHE_DIRECTORY, by default ~/.cache in linux and C:/Users/<user>/AppData/Localin windows

maoe · 2020-06-12T08:12:37Z

Thanks. I’ll ll try that later. I’m having the same issue in our private in-house repository too so there may be a real issue. I’ll try to make a smaller reproducer.

maoe · 2020-06-12T22:54:25Z

I made a tiny reproducer: https://github.com/maoe/hls-reproducer. This project builds fine with cabal but if you run haskell-language-server MyLib.hs:

maoe · 2020-06-12T22:58:16Z

And if you replace myId with id in the definition of template, hls works fine.

jneira · 2020-06-12T23:00:17Z

Thanks for the small reproducer, i hope it will help to identify the cause

maoe · 2020-06-12T23:15:43Z

Currently available workaround for this issue is to define myId in a separate module. See maoe/hls-reproducer@c4add31

Loading the hls-reproducer example in VSCode with ghcide HEAD works fine for me. The command line is a diagnostic tool, but not always equivalent to loading in an IDE.

Trying to build threadscope with Nix gets stuck in:

@maoe can you load the module MyLib in your editor (with hover and other lsp features), like @pepeiborra? please, use the just released version or master

@jneira I just tried haskell-language-server 0.2 (7ad18cf) and a fairly recent ghcide (035019d) with VSCode 1.46.1 on macOS. I used GHC 8.10.1 except for HIE.

"languageServerHaskell.hieVariant": "haskell-language-server"

This reproduces the error.

"languageServerHaskell.hieVariant": "ghcide"

This also reproduces the error.

The ghcide extension instead of the Haskell Language Server extension

I couldn't get the ghcide extension working. It prints a lot of errors as follows:

"languageServerHaskell.hieVariant": "haskell-language-server"

It works as expected. Because HIE doesn't support 8.10 I used 8.8.3 for this demonstration.

maoe · 2020-07-06T13:28:58Z

The obvious question would be if hls works with GHC 8.8.3. The answer is no. It fails in the same way as GHC 8.10.1.

maoe · 2020-08-22T22:38:01Z

I confirmed that ghcide from wz1000/ghcide on the hls-3 branch fixes this issue. For those who are eager to try, add the following snippet to cabal.project when building hls:

source-repository-package
  type: git
  location: https://github.com/wz1000/ghcide.git
  tag: 493e960a7aa73f64ce3b631c69f6a60aa3a5b5f0

maoe · 2020-08-22T23:10:43Z

I still see this issue in our in-house codebase even with the patched ghcide. I'll try to make a reproducer.

jbransen · 2020-10-15T09:31:00Z

I can reproduce this issue with https://github.com/jbransen/hls-bug using haskell-language-server-8.8.4 (75c4ebc). stack build succeeds, haskell-language-server-8.8 A.hs fails with:

File:     .../hls-bug/A.hs
Hidden:   no
Range:    14:11-14:13

FWIW I tried some intermediate commit of haskell/ghcide#836 with hls and it fixed the issue in our codebase. I had to disable a few plugins to build hls though. So I think #463 is going to fix this issue.

jbransen · 2020-11-04T07:36:16Z

I can confirm that #530 seems to have solved this! Latest master now works fine for my bigger projects.

jneira · 2020-11-04T08:21:57Z

@jbransen great! thanks for confirming it
