I have a problem with haskell-language-server. I use alex+happy and they generate files inside the dist-newstyle directory. Cabal can't repl those files because of the "Unrecognized target" error:

Expected a meta-target 'all' or component kind filter or component name or
package name or package directory or package .cabal file or component name or
module name or file, rather than

So hls also refuses to work.

My setup:
vscode
ghc-8.8.4
Kubuntu 20.04

I'm not sure if we have support (yet) for preprocessed files, especially the ones generated in dist-newstyle. Can you provide an example project where this occurs anyway?

Can we ignore such files somehow?

Yes, you can specify certain files to ignore with a hie.yaml file in your project root by specifying what component each file should build, or specifying a "none cradle" if it shouldn't be built:

cradle:
  multi:
    - path: "./src"
      config: { cradle: {cabal: {component: "lib:foo"}} }
    - path: "./test"
      config: { cradle: {cabal: {component: "test:blah"}} }
    - path: "dist-newstyle"
      config: { cradle: { none: } }

It didn't work.

A configuration that might work could be:

cradle:
    multi:
    - path: "dist-newstyle"
      config: { cradle: { none:  } }
    - path: "./"
      config: 
        cradle:
          cabal:
            - path: "./"
              component: "lib:cabal-test"

            - path: "app/Main.hs"
              component: "cabal-test:exe:cabal-test"

            - path: "test"
              component: "cabal-test:test:cabal-test-test"

@Abbath You can check a complete hie-yaml configuration syntax here (including a example on how to ignore directories): https://github.com/mpickering/hie-bios#ignoring-directories

E.g. show your hie.yaml and the output of haskell-language-server <some-file-path-to-load>

Thank you! The cradle root directory seems to be off:

Cradle 
  { cradleRootDir = "/home/a66ath/Calculator/Calculator"
  , cradleOptsProg = CradleAction: Cabal
  }

and the respective path: Consulting the cradle for "/home/a66ath/Calculator/Calculator/src/Calculator.hs"
while the path with dist-newstyle is:
/home/a66ath/Calculator/dist-newstyle/build/x86_64-linux/ghc-8.8.4/Calculator-0.5.1.0/build/Calculator/HappyParser.hs'

Note the discrepancy between:
/home/a66ath/Calculator/Calculator/
and
/home/a66ath/Calculator/dist-newstyle/

So, my hunch would be that hie.yaml is located in "/home/a66ath/Calculator/Calculator" and it should be located in the parent directory. In general, it should be on the same level as any stack.yaml/cabal.project.
If this hunch is wrong, could you share your project or at least show the project structure in more details? E.g. cabal.project, *.cabal files and directory structure

@fendor ok, it fixed the Unrecognized target problem. But it still breaks on an Alex-generated file.
