Doesn't jump to literate Haskell file and doesn't reload it either

[turion]

For modules defined as literate Haskell, jumping to source doesn't work. Similarly, changes to these files don't get reloaded automatically.

To reproduce:

git clone https://github.com/turion/essence-of-live-coding
cd essence-of-live-coding
gen-hie > hie.yaml
codium

(This is assuming VSCodium with the ghcide extension as editor.)

1. Navigate to a test file like essence-of-live-coding/test/Main.hs
2. Navigate to line 21
3. Press F12 or select "Jump to source"
4. "No definition found for 'LiveCoding'"
5. Change anything in the module essence-of-live-coding/LiveCoding.lhs, e.g. add a definition
6. Try to use this definition in the test
7. It's not found

$ ghcide --version
ghcide version: 0.2.0 (GHC: 8.8.3) (PATH: /nix/store/hvdw1f7nwjns5j3jxd9wjkx4jnvb8vw7-ghcide-0.2.0/bin/ghcide)

(I'm running from a nix-shell)

I forgot to add, it doesn't work either if no hie.yaml file is added.

Do other features work with literate haskell files for you? In my experience, ghcide does not even start. I've had better luck with haskell-language server, on the other hand.

[turion]

@pepeiborra No features really work with literate haskell files. I can add a syntax error to a literate haskell file and nothing will happen. But at least somehow the file was loaded at some point because other files that import it don't fail.

The original literate Haskell support was contributed by @hsenag. I don't think many other people use literate Haskell (I generally advise against it) so this might be something that requires an interested contributor to tackle.

[hsenag]

@ndmitchell I added .hs-boot, not .lhs: digital-asset/daml#2827

I think lhs was done here by @CodiePP: digital-asset/daml#2803 haskell/ghcide#31

[jneira]

@turion had you the opprtunity to check lhs files with haskell-language-server (ghcide is being deprecated as external executable)?

[turion]

Yes, it works. Thank you!
