haskell-language-server-wrapper from emacs behaviors is different from command line #154

Closed arademaker closed 1 year ago

arademaker commented 1 year ago

If I call the haskell-language-server-wrapper from the command line in the main folder of my project (created with stack), I get the outputs below. Not sure what the for "/Users/ar/Temp/lixo/a" means, but it seems to work as expected.

But, in the *lsp-haskell::stderr* buffer, I have a different result. Emacs found another version of GHC.. The current directory was wrongly associated with the parent folder of the project folder... How can I fix it? What am I missing? 

No 'hie.yaml' found. Try to discover the project type!

More details

VS Code started just fine. Inspecting the processes I found

% ps aux | grep has
ar               50967   0.0  0.0 33588072    192 s002  R+    3:27PM   0:00.00 grep has
ar               50445   0.0  3.4 1108409952 571204   ??  Ss    3:26PM   0:01.45 /Users/ar/.ghcup/hls/1.7.0.0/lib/haskell-language-server-1.7.0.0/bin//haskell-language-server-8.10.7 --lsp -d -l /var/folders/b_/7nbv248s2nq019mcx58xrrb80000gn/T/hls.log
ar               48413   0.0  0.3 1107893416  44664   ??  S     3:21PM   0:01.62 /Users/ar/.ghcup/hls/1.7.0.0/lib/haskell-language-server-1.7.0.0/bin//haskell-language-server-9.0.2 --lsp

So VS Code found the right version of HLS

/Users/ar/.ghcup/hls/1.7.0.0/lib/haskell-language-server-1.7.0.0/bin//haskell-language-server-9.0.2 --lsp

But Emacs somehow is ignoring the information from my project (that uses GHC 9.0.2) and it is calling HLS 8.10.7:

/Users/ar/.ghcup/hls/1.7.0.0/lib/haskell-language-server-1.7.0.0/bin//haskell-language-server-8.10.7 --lsp -d -l /var/folders/b_/7nbv248s2nq019mcx58xrrb80000gn/T/hls.log

I believe we can close now given my last comment in https://github.com/haskell/haskell-language-server/issues/3114#issuecomment-1221349783.
