Hi, thanks for the bug report, is it possible that the quad.cabal file generated from package.yaml does not include the new module when hls did not find it? |

Hello. So I tested that out. I created a new module called
It seems like it was able to detect it just fine, I think. Stack seems to recognize it as well because both the

Hey @hsek could you try doing the following things outside of vscode?
I think I'm having the same issue (also using stack, but via vim), where until I manually recompile my lib, hls refuses to acknowledge its existence. Additionally I would be grateful if you could also try
When I do the same, instead of getting the error reported to me in the test suite, I get a "cannot find package blabla..." error, referring to the library again. The purpose of this is to hopefully see if there's more of a link between the first (your) error case, and #735 |

I followed what @googleson78 asked. Installed hls in { pkgs ? import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/60cce7e5e1fdf62421ef6d4184ee399b46209366.tar.gz") {} }:

I made the repo public in case someone wants to reproduce the issue. I isolated it in a nix environment, so hopefully that would make things easier. https://github.com/hsek/quad-ci/tree/fa44eb79b6b6085fc7326f88973e5047936d7efd |

I think it the root issue is the same as #366, so the resolution and the possible workaround will be the same too. |

Your environment
Output of

Which OS do you use:
NixOS 21.05
Which lsp-client do you use:
VSCode's official hls plugin
Describe your project (alternative: link to the project):
I'm using
stack. Following the simple haskell handbook project.Contents of
hie.yaml:N/A
Steps to reproduce
The project is structured this way:
Then when trying to import the
Dockermodule, HLS complains about how it can't find it.What's weird is that previously, it couldn't find the
Coremodule. Not sure what changed, and weird that this time it doesn't know what theDockermodule is even if it's just in the same folder asCore.Expected behaviour
It's supposed to import the project's modules just fine in the test.
Actual behaviour
It can't find the modules properly.
Include debug information
So I tried following the instructions, and restarted VSCode. Now it seems to detect it normally. But does it mean I have to restart VSCode every time I add a new module? Weird that when I tried restarting the LSP server, it still had the same issue so I had to restart the entire VSCode for it to work.
