Can not get elm-analyse and elm-language-server work

Learn
#1

I have a project with the code from Elm’s tutorial.
Page itself works great, elm-format also works well. But elm-language-server and elm-analyse fails with same error:

`--> elm-analyse src/Main.elm
Fetching package information from package.elm-lang.org.

As I figured out all modules located in local cache inside ~/elm directory. How I can make elm-analyse and elm-language-server load modules form local cache?

Environment:
installed globally with yarn

  • elm@0.19.0-no-deps
  • @elm-tooling/elm-language-server@1.4.1
  • elm-analyse@0.16.4
  • elm-format@0.8.2
    installed with system package manager
  • node v10.16.3

I think this turned out to bo a problem with elm-analyse? https://github.com/elm-tooling/elm-language-server/issues/176

Here is my bug report against elm-analyse.

I looked through the file-gather.ts and did not saw any mention of a local cache. It tries to load modules only from the project/elm-stuff/ directory.

#4

Can you try if you hit the same problem with the vscode extension? https://marketplace.visualstudio.com/items?itemName=Elmtooling.elm-ls-vscode

#5

I do not really know how to use the VSCode, I installed extension over VSCode and still have no auto-completion and syntax check. All tools: elm-analyse, elm-test, elm-format, elm-language-server and elm itself accessible with the PATH environment variable.

VSCode installed from flathub. JavaScript and Python extensions from Mircrosof works well.

#6

This should outline all you need to do

Please also make sure that you have a valid elm.json that actually points to your .elm files

#7

Got it work. I should use “File->Open Folder” instead of “File->Open File”.

I wrote one example from the elm tutorial and auto-completions still works.
Same code with the nvim makes the language server fail.

#8

Great you got it to work by changing working directory.

I think it might be improved in the future with better error messages or search for elm.json could be recursive upwards the directory structure (probably error prone by itself).

#9

Yes the VSCode plugin works. But console elm-analyse and elm-language-server with language-server-neovim still doesn’t.

Also elm-analyse outputs There is no elm.json file in this directory. elm-analyse will only work in directories where such a file is located. if I call it from non project directory.
