Elixir-LS fails in neovim
Hi all,
I have configured my neovim according to this thread - thanks for the awesome work on that one, btw!
As I am working on an Arch-based Linux system (Artix, to be precise), I had installed the language server from the AUR, where the package version 0.13.0 worked nicely.
However, after upgrading to package version 0.14.6, every time I open an elixir file I’ll get the message Client 1 quit with exit code 1 and signal 0 after a few seconds. Restarting the server with :LspStart will result in the same message.
I have tried installing elixir-ls via mason as well, which will display the same error. Downgrading to v013.0, which worked formerly, also doesn’t help.
I even created a new user, set up neovim from scratch for him, and ran into the same problem. This is also true when I use the exact init.lua-file given in the tutorial - with the path to elixir-ls set correctly, of course.
Checking the lsp.log reveals the following error, which unfortunately I can’t make much of:
[START][2023-06-15 13:47:58] LSP logging initiated

I’d appreciate any help or pointers where to continue searching a solution!
Thank you for your trouble!

BTW, I’m an ArchLinux user, too. The erlang package from arch official repo has been updated to 26 recently. If you’re using pacman to update all software packages to the latest version, including erlang, then it can break elixir-ls. I’ve encountered the same issue a few days ago. I’d recommend you use asdf to manage different erlang/elixir versions. You can install it from AUR under the asdf-vm package name.

ElixirLS 0.15.1 with support for OTP 26.0.2+ is out

I am using Elixir 1.14.5 and Erlang 25.3.2.2 and compiling ElixirLS locally with those versions, I use LunarVim with it and have no problems.
I am not keeping up super closely with all the developments but I am seeing increased reports on the forum that people have issues with Erlang/OTP 26 so I’d hold on to 25 for the time being.

I don’t use Mason’s installed ElixirLS. I have it locally and update it from GitHub once every 24h and build it like so (this is a snippet from my own homemade “update my machine” script, hence the pushd and popd commands):
(
pushd ~/bin/elixir-ls &&
git reset --hard HEAD &&
git pull &&
mix deps.get &&
MIX_ENV=prod mix compile
MIX_ENV=prod mix elixir_ls.release &&
popd || return
)
I also make sure it uses the latest stable combo of Elixir and Erlang. I use asdf local for that, though maybe that’s not optimal.
Then I have this in my LunarVim’s init file:
local root_pattern = require("lspconfig").util.root_pattern
require 'lspconfig'.elixirls.setup {
filetypes = { "elixir", "eelixir", "heex", "surface" },
root_dir = root_pattern("mix.exs", ".git") or vim.loop.os_homedir(),
cmd = { "/Users/dimi/bin/elixir-ls/release/language_server.sh" },
}
Though I should probably take another look at the filetypes.

Which Erlang/OTP version are you using? elixir-ls seems not working properly with OTP 26 from my test. Try downgrade to OTP 25 and recompile elixir-ls.

I don’t use all of them but those that I use: yes, they still work.
Yep. You can override each separate LSP without affecting anything else.
