Can't go to definition when trying to go to function in other module

[mawkler]

Hi! I'm trying out this plugin, but I can't seem to do vim.lsp.buf.definition() to jump to functions in other modules.

To reproduce,

1. Clone https://github.com/robsonpeixoto/elixir-ls-go-to-definition-bug.

2. Open lib/bug.ex with the config below

3. In lib/bug.ex, move your scursor to ModA.say_hi() and call :=vim.lsp.buf.definition(). Here's what the file looks like:

   defmodule Bug do
     use MacroA
   
     def hello do
       ModA.say_hi()
     end
   end
   

4. Nothing happens

Here's the minimal config that I'm using:

local root = vim.fn.fnamemodify("./.repro", ":p")
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

local plugins = {
  {
    "elixir-tools/elixir-tools.nvim",
    version = "*",
    event = { "BufReadPre", "BufNewFile" },
    config = function()
      local elixir = require("elixir")
      local elixirls = require("elixir.elixirls")

      elixir.setup {
        projectionist = {
          enable = false
        }
      }
    end,
    dependencies = {
      "nvim-lua/plenary.nvim",
    },
  }
}

require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

It does however work when navigating to symbols in the same file, like if I would try to go to hello() in that file.

Its probably still indexing your project, you can run :ElixirOutputPanel to see if there are any logs in there that show anything

[mawkler]

@mhanberg The output of :ElixirOutputPanel contains this:

[Warning] error: module MacroA is not loaded and could not be found

I apologize if I'm doing something dumb here, I just started using Elixir, so I'm a complete novice.

I see, you might want to take this to the ElixirLS repo to ask.

This plugin merely handles starting and configuring it for you.

But, as a community we are starting a new LSP initiative and are working on a new official one, so support on the existing ones is reduced as we push forward.
