Dear all

I apologize if this has already been discussed elsewhere but I did not come up with a solution.

I installed the melpa version of eglot ` eglot-jl 20221128.1655` but it has some issues:

1. Each time I open a `.jl` file (either in a project or in an “isolated” file), to start the eglot server I need to always do a `M-x eglot-jl-init` and a `M-x eglot`. Then thinks works (almost see point 2). Is it possible to automatize the process such that each time I open a `.jl` file I automatically start the process without typing each time `M-x eglot-jl-init`, `M-x eglot`?

2. The autocomplete feature does not work. I understand that the first time should take some minutes, but even after half an hour, there are no positive signs.

Possibly relevant info about my installation. I am on Mac OS X and using Emacs for Mac last version (28.2).

This is the portion of my `.emacs` setup (I do not entirely understand what it is doing: just blindly copied from snippets on this thread)

```julia
(require 'yasnippet)
(use-package julia-mode
  :mode "\\.jl\\'"
  :interpreter ("julia" . julia-mode)
  :init (setenv "JULIA_NUM_THREADS" "6")
  :config
  (add-hook 'julia-mode-hook 'julia-repl-mode)
  (add-hook 'julia-mode-hook 'eglot-jl-init)
  (add-hook 'julia-mode-hook 'eglot-ensure)
  (add-hook 'julia-mode-hook 'company-mode)
  (add-hook 'julia-mode-hook (lambda () (setq julia-repl-set-terminal-backend 'vterm)))
  (add-hook 'julia-mode-hook (lambda () (setq julia-repl-set-terminal-backend 'vterm)))
  (add-hook 'julia-mode-hook (lambda () (setq julia-repl-set-terminal-backend 'vterm))))

(use-package julia-repl)

(setq eglot-jl-julia-command "/Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia")
(setq julia-repl-executable-records
      '((default "/Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia")
	(master "/Applications/Julia-1.8.app/Contents/Resources/julia/bin/julia")))

```

I don’t immediately see any gross mistake in your `init.el` stanza; it should already start `eglot` automatically. Could please start a fresh Emacs, open a `.jl` file in it and look for a buffer called something like `*EGLOT (xxx/julia-mode) events*` ?

If that buffer exists, it means that `eglot` did start. In that case, it will be interesting to see the beginning of the contents of that buffer, between the first line (it should start with `[internal]`) and the first server reply (it should be marked by a line starting with `[server-reply] (id:1)`).

Hopefully the same `*EGLOT events*` buffer will have some info regarding this issue. Look for lines starting with `[stderr]`, especially if they look like julia error messages or stack traces.

Judging by the paths set in your init file, I’m assuming you use Julia 1.8?

Thanks, @ffevotte for your reply. Yes I am using julia 1.8.2. WRT to you questions:

1. If I start a `.jl` nothing happens although the file is correctly recognized as a julia file (highlighting colors etc … see image below)

But there is no eglot buffer.

Below you can find the first part of the \*EGLOT buffer obtained after the usual `M-x eglot-jl-init` and `M-x eglot`. To wrap up I am not able to start automatically the process.

1. This is the output in the \*EGLOT buffer when I start typing (and hopefully autocompleting) some code

Try running manually in your newly opened julia-mode buffer:

1. `M-x eglot-jl-init`
2. `M-x eglot`
3. `M-x company-mode`

If that fixes autocompletion, then it means the problem entirely comes from things not starting automatically like they should.

  

Now to investigate why things are not automatic, take a look at the value of the julia mode hook:

C-hv`julia-mode-hook`RET

Thanks @ffevotte … now everything works

I am ashamed to tell you that I realized I did not install `company`. That somehow screwed up the whole auto-loading thing. Now everything works smoothly.

Sorry for the noise.
