"Connection state changed" :change "killed: 9"

[tamasgal]

I need some help getting eglot working again. It worked for a while but now it keeps crashing and the buffer output does not really reveal (at least to me) a meaningful hint what's going wrong.

Julia 1.9.3
eglot: 1.15

  [2b0e0bc5] LanguageServer v4.4.0
  [cf896787] SymbolServer v7.2.1

This is what I get when I start eglot in my Doom Emacs setup, any ideas?

Hmm, it looks like eglot-jl directly uses your default environment, when by default it should use a specific environment. What is the value of eglot-jl-language-server-project? Have you customized it?

[tamasgal]

Yes, I have set it to use my 1.9 environment but I already uncommented that line. It seems that it still picks that up. How do I force it to use the default one?

[tamasgal]

Sorry for my ignorance, just figure it out:

(after! eglot-jl
  (setq eglot-jl-language-server-project eglot-jl-base))

Still got an error:

Thanks! Now could you please try to see whether this environment seems to be working in an interactive process?

E.g. run these commands and please report back whether everything works:

$ julia --project=~/.emacs.d/.local/straight/repos/eglot-jl
julia> import Pkg
julia> Pkg.resolve()
julia> Pkg.instantiate()
julia> empty!(LOAD_PATH); push!(LOAD_PATH, "@")
julia> using LanguageServer
julia> using SymbolServer

OK, I'll note this debug procedure for the next time ;) resolve() helped, now it's working!
