Installing elixir LSP to use with coc vim

[peak cipher]

I'm trying to configure Elixir LSP on my MacBook and tried to follow this video https://www.youtube.com/watch?v=FXpsUh0Hs9Y. But in the end the language server fails to load. How can I set up the language server?

I follow through everything accordingly

Are you doing it with the coc-elixir extension?

I skimmed through the video, it seems he's also using Coc, so I've had random issues with that, just trying to remember how I sorted them

For example in :CocConfig (your coc-settings.json file) I do have:

  "elixir.pathToElixirLS": "~/.elixir-ls/release/language_server.sh"

Because at one point it stopped finding the server

[peak cipher]

yes I'm using coc vim

[peak cipher]

whats the path for that file?

[sweet vortex]

That's just where I have it installed

You should have a similar path or you'll need to find where it is

If you manually set the path it should rule out Coc not being able to find it

[peak cipher]

It's not giving me that error

it's giving me this one

[peak cipher]

For any one having this error you just need to add this to your coc-settings.json

{
    "codeLens.enable": true,
    "emmet.includeLanguages": {"eelixir": "html", "smarty": "html", "javascript": "html"},
    "elixir.pathToElixirLS": "~/.elixir-ls/release/language_server.sh",
    "languageserver": {}
}

Sorry, been away most of the day

[sweet vortex]

What was the exact issue that led to this solution?

Curious to know too because for sure others will run into this

[peak cipher]

No worries

I was just going by trial and error

this popped up somewhere and it worked

[sweet vortex]

Ah, I see

I've had similar-ish errors, just didn't write down at the time what it was, it was also the the .js files

It's made me think of switching to using nvim's in-built LSP but Coc does provide a lot of things since it has been around for a while

[peak cipher]

Yeah, this LS when its working is really good but some times is a pain in the bum

[peak cipher]

between this one and coc which one do you prefer?

[sweet vortex]

I haven't had a chance to use the nvim one yet 😅

If/when I do, I'll let you know

[peak cipher]

btw @sweet vortex is LS is supposed to give inline diagnosis (build errors and warnings) right?

[peak cipher]

perfect 💪🏻

[sweet vortex]

Yes, here's an example:

Dialyzer messages are an issue since they're so long they get cut off, however you can use :CocDiagnostics and I'm sure there's a way to increase the number of characters shown to stop it getting cut

[peak cipher]

oh yes it's working

i thought it wasn't

[sweet vortex]

It can take a second sometimes

Or a few

[peak cipher]

yeah 😂

as long they appear that's fine for me

[sweet vortex]

Yeah

Have fun 🙂
