installing ghcide with stack requires a lot of extra-deps

[SamKacer]

Apologies if this isn't appropriate place to ask, but wasn't sure where else to go.

I've recently returned to programming in Haskell and before I remember I used ghcide, but now there is a much newer version of ghc, so ghcide doesn't work for the project I am working on now, so I am trying to install the new version.

I am using latest stack on windows 10. I am using following command to install ghcide, but I get the following problems. Essentially it asks me to add quite a lot of dependencies to extra-deps.

Is this normal and to be expected? Or should I just add everything, install ghcide for my current ghc version, and then just remove the extra-deps from my project?

stack build ghcide --copy-compiler-tool

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for ghcide-0.5.0:
    hie-bios-0.5.1 from stack configuration does not match >=0.7.1 && <0.8.0  (latest matching version is 0.7.1)
    hie-compat needed, but the stack configuration has no specified version  (latest matching version is 0.1.0.0)
    implicit-hie-cradle must match >=0.2.0.1 && <0.3, but the stack configuration has no specified version  (latest
                        matching version is 0.2.0.1)
    lsp-test-0.10.3.0 from stack configuration does not match >=0.11.0.2 && <0.12  (latest matching version is 0.11.0.7)
needed since ghcide is a build target.

Some different approaches to resolving this:

  * Recommended action: try adding the following to your extra-deps
    in C:\Users\Sam\OneDrive - University of Glasgow\FP\AE\prof-scraper\stack.yaml:

- hie-bios-0.7.1@sha256:27b88c6f541e435a41e0c37f94fa286e78eb0065a151a1c599662e6cd0b88c80,11260

- implicit-hie-cradle-0.2.0.1@sha256:c6892ef9c16ba1e19f497a119c039a5845f46b93dd67538f37d4c002b222d4c1,2568

hi, don't worry, questions are always welcomed.
First of all we would recommend to use haskell-language-server, it is the main LSP server for Haskell nowadays and it is automatically installed by the haskell vscode extension (if you are using it as editor). It has more features and a extensible plugin mechanism that adds formatters support, integration with hlint, etc.
If you still want install ghcide, note we just have changed the default stack.yaml's but we have kept an stack-windows.yaml for ghc-8.10 that should work with a simple stack build --stack-yaml stack-windows.yaml.
did you try master using that stack-windows.yaml?

EDIT: I've just note that you were trying install ghcide from your project, the above suggestion needs this project to be checked out

[jneira]

@SamKacer Another alternative could be copy the stack-windows.yaml in your project as, f.e., stack-ghcide.yaml and make a stack build ghcide --copy-compiler-tool --stack-yaml stack-ghcide.yaml

And finally list all needed packages in the build command could work too: stack install fuzzy-0.1.0.0 ghc-check-0.5.0.3 [rest of needed extra-deps here] ghcide --copy-compiler-tool

@jneira thanks for recommending the Haskell extension for VS code. It happens to be the editor I am using, and after installing the extension, everything is working great!

It seems to provide all the features I remember having from the ghcide extension, so no need to install that. but I appreciate your advice on that :)
