Apply hint never returns

[nmichael44]

First, let me thank you for all your efforts in building a Haskell IDE. It is something that the language desperately needs.

Your environment

haskell-language-server version: 0.7.0.0 (GHC: 8.8.4) (PATH: /home/neo/.config/Code/User/globalStorage/haskell.haskell/haskell-language-server-0.7.0-linux-8.8.4) (GIT hash: 6a692de3308c06d8eb7bdf0f7b8a35b6e9a92610)
Tool versions found on the $PATH
cabal:		3.2.0.0
stack:		2.5.1
ghc:		8.8.4

Which lsp-client do you use:
VS Code
Describe your project (alternative: link to the project):
Stack project using package.yaml
Contents of hie.yaml:
I don't have this file at all so I am picking up the default behavior.

Steps to reproduce

Whenever VS-code highlights a piece of code with a blue squiggly line like suggesting some hint/refactoring, if I click on quick fix, the hint never happens and I get a small window on the bottom right of the screen saying "applying hint" (see attached image) but it never gets applied. Eventually I just have to hit cancel to get rid of the window. This happens for every hint.

Thank you for trying it and report the issue.
I think the issue is similar to #646: an underlying error (that may be different) makes the pop up never finishes, instead closing it with a error message.
The error will be likely related with #591 so the workaround provided there may help you to make hlint work.
I am gonna close this one if you dont mind, you can track the progress in the linked ones.

i enabled logging in VS and I see this in the log:
/opt/ghc/8.8.4/lib/ghc-8.8.4/settings: openFile: does not exist (No such file or directory)

so i guess it is the same issue as the other tickets you mentioned.

I created the symbolic link as you described in the other ticket and the problem was fixed. Thank you. I have closed the ticket.

Is this problem solved completely? On windows 10 with ghc-8.8.4, I failed to compile the hls from the source due to the failure of compiling with-utf8 executable. @jneira

According to this post, I create a symbolic link in the directory D:\bin\stack\x86_64-windows on windows by:

New-Item -ItemType SymbolicLink -Path "ghc-8.8.4" -Target "C:\Users\<your user name>\AppData\Local\Programs\stack\x86_64-windows\ghc-8.8.4"

This works. I post this in case that someone who meets the same problem on windows tries hard to figure out how to create a symbolicLink on windows.

it still is not solved, but there are other issues about, the windows specific one is #615
Hopefully my recent pr #1225 will solve the issue for all os's
