julia lsp exiting immediatly

[luiswirth]

Summary

The julia lsp does not work at all for me in helix.
Everytime I open up a file, it immediatly exits.

Reproduction Steps

I tried this:

1. hx main.jl in julia project with LanguageServer.jl installed.

I expected this to happen:
Julia lsp working

Instead, this happened:
Julia lsp exited.

maybe i'm just confused about the way I need to activate the julia environment

[the-mikedavis]

The err <- lines in the log are what julia is printing to stderr when run. You should see the same when running the command for that language server: julia --startup-file=no --history-file=no --quiet -e "using LanguageServer; runserver()". It looks like you may need to install the language server's package

[luiswirth]

Okay, this just helped me, partially solve it. I now installed the LanguageServer.jl globally instead of only locally for my project. now the lsp works 🥳 .
But I'm not sure if this is what I want... Does this pickup the packages I installed locally for a project (using environments)?

[koalazub]

I'm getting the same issues. I've tried updating languages.toml with this added to attempt to trigger the LSP:

[[language]]
name = "julia"
scope = "source.julia"
injection-regex = "julia"
file-types = ["jl"]
roots = ["Project.toml", "Manifest.toml", "JuliaProject.toml"]
comment-token = "#"
language-servers = ["julia"]
indent = { tab-width = 4, unit = "    " }

[language-server.julia]
command = "julia"
args = [
    "--startup-file=no",
    "--history-file=no",
    "-e",
    "using Pkg; Pkg.activate(\"@LanguageServer\"); using LanguageServer, SymbolServer; runserver()"
]

After installing Julia I would then add the LSP package with :

julia -e 'using Pkg; Pkg.add("LanguageServer")'

I've tried this both in my MacOS environment and when in my nix devShell to get it going but with no success.

There are some unknowns here and I'm not ruling out issues based on the configuration of my machine. But I have been able to get the LSPs on all other languages I've needed to use to work just fine via my usual methods. Thus my attempt at bumping this. Hope I've given enough info
