Not working with kak-lsp

Expected Behavior

When running elm-language-server with kak-lsp, should display errors, show hints, etc.

Current Behavior

ELS is failing to compile elm & can’t find an input file. In the debug buffer of kakoune, it errors with:

Possible Solution

Steps to Reproduce (for bugs)

Download & setup elm-language-sever and kak-lsp as described in the documentation.

Context

Just trying to get a great editor experience with Elm!

My elm-tooling.json file looks like:

{
    "entrypoints": ["./src/elm/Main.elm"]
}

Your Environment

• ELS Vesrion: 2.02
• Editor used: Kakoune v2020.09.01
• Environment name and version (e.g. node.js 5.4): Node v12.20.2
• Operating System and version: MacOS Big Sur 11.2.3
• Kak-LSP Version: 8.0.0

Ok the spec says that "true" is valid`

linkedEditingRangeProvider?: boolean | LinkedEditingRangeOptions | LinkedEditingRangeRegistrationOptions;

so this is a bug in lsp-types, the library kak-lsp uses. I’ll submit a fix and report the status in kak-lsp/kak-lsp#484. Sorry for the troubles and thanks for reporting.

This is fixed on the kak-lsp side, thanks so much @krobelus!
