Erroneous detection of Stack projects
chris-martin opened this issue · 9 comments
Apologies as usual if this is an outdated issue or the wrong project; I'm encountering this problem via several levels of indirection (vscode haskell plugin, haskell-language-server, ...) and so I do not know exactly the infrastructure or how to detect what relevant versions of things are. I recently upgraded to NixOS 22.11 and have experienced this regression.
I have had to go back to placing this hie.yaml file in all of my repositories:
cradle:
cabal:My projects all have a cabal.project file, and none of them has a stack.yaml file. But the IDE has regressed to perpetually trying to use Stack, which I don't even have installed, unless this hie.yaml is present.
Thanks for the bug report!
This is most likely caused by implicit-hie which is an additional indirection for cradle detection.
hie-bios in HLS performs no auto-detection at all.
My investigation shows that 1.8.0.0 was using implicit-hie 0.1.2.7 most likely. 1.9.0.0 was using 0.1.4.0 most likely.
The only code difference seems to be these two:
According to @Avi-D-coder, 0.1.2.7 and 0.1.4.0 (0.1.4.0 is a re-publish of 0.1.2.7) are the same version, so it might be a longer standing issue even.
Also, @hasufell, since @chris-martin is using nixpkgs, nixpkgs follows stackage and stackage included the version for at least a couple days, it is actually possible that the nixpkgs version ships with version 0.1.3.0.
Additionally, our buildplan in HLS always excluded 0.1.3.0.
@chris-martin can you share your exact project or at least the whole file-tree?
Here is one example project:
typeclasses/ascii-char@f6e082f
-
fish> cd (mktemp -d) fish> git clone https://github.com/typeclasses/ascii-char.git fish> code ascii-char -
Open
ascii-char/library/ASCII/Char.hs -
VSCode launches and displays a popup that says:

Perhaps haskell-language-server ought to be printing version numbers for more of its dependencies.
Also perhaps implicit-hie should confine its selection to only the tool stacks which are installed on the system?

Hard agree on that
Is this still relevant or did a subsequent release fix this?
I haven't seen the issue in a while, will reopen if it recurs.
