Hello,
I’m trying to get the lsp server working with Neovim.
I installed it with Mason, added some configuration for lspconfig.
When I launch a .ex file and if I look to LspInfo, I have the elixirls launched.
But I only get the “hover” functionality, no “go to definition”, no “rename” etc.
How did you guys do?

It’s a fairly standard config, have you followed the tutorials? I never had a partially working ElixirLS and I am pretty noob at NeoVim.

I’d recommend using a distro like GitHub - LazyVim/LazyVim: Neovim config for the lazy · GitHub .
My Neovim config is based around LazyVim. The awesome part is that nvim-treesitter, nvim-lspconfig and all the configuration to make LSP work is already in place.
I’ve added elixir support to LazyVim and it was just a matter of extending the configs a little bit:

ahahah thanks for saying I’m a noob 
, I’m definitely not an expert.
Ok so this is some of my lsp file with the keymaps and I’m registering lsp servers
(I’ve been doing a few tests that’s why there is a for loop then elixirls. etc)
local servers = {
"cssls",
"dockerls",
"elixirls",
"gopls",
"html",
"jsonls",
"lua_ls",
"svelte",
-- "tailwindcss",
"taplo",
"tsserver",
}
local server_settings = {
["lua_ls"] = {
Lua = {
runtime = { version = "LuaJIT" },
diagnostics = { globals = { "vim" } },
workspace = {
library = vim.api.nvim_get_runtime_file("", true),
},
},
},
["yamlls"] = {
yaml = {
keyOrdering = false,
},
},
}
local server_with_disabled_formatting = {
["tsserver"] = true,
["lua_ls"] = true,
["tailwindcss"] = true,
["cssls"] = true,
}
mason.setup()
mason_lsp.setup({ ensure_installed = servers })
local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities = cmp_lsp.default_capabilities(capabilities)
-- The biding for every servers
local on_attach = function(client, bufnr)
local bufopts = { noremap = true, silent = true, buffer = bufnr }
bufopts.desc = "Go to definition"
vim.keymap.set("n", "gd", vim.lsp.buf.definition, bufopts)
bufopts.desc = "Go to type definition"
vim.keymap.set("n", "gt", vim.lsp.buf.type_definition, bufopts)
bufopts.desc = "Go to implementation"
vim.keymap.set("n", "gi", vim.lsp.buf.implementation, bufopts)
bufopts.desc = "Show diagnostics"
vim.keymap.set("n", "gl", vim.diagnostic.open_float, bufopts)
bufopts.desc = "Go to next diagnostics"
vim.keymap.set("n", "]d", vim.diagnostic.goto_next, bufopts)
bufopts.desc = "Go to prev diagnostics"
vim.keymap.set("n", "[d", vim.diagnostic.goto_prev, bufopts)
bufopts.desc = "Telescope diagnostics"
vim.keymap.set("n", "<leader>ld", ":Telescope diagnostics<CR>", bufopts)
bufopts.desc = "Rename"
vim.keymap.set("n", "<leader>lr", vim.lsp.buf.rename, bufopts)
bufopts.desc = "Code action"
vim.keymap.set("n", "<leader>lc", vim.lsp.buf.code_action, bufopts)
if server_with_disabled_formatting[client.name] then
client.server_capabilities.documentFormattingProvider = false
client.server_capabilities.documentRangeFormattingProvider = false
end
end
for _, server in pairs(servers) do
lsp[server].setup({
capabilities = capabilities,
on_attach = on_attach,
settings = server_settings[server],
})
end
lsp.elixirls.setup({
filetypes = { "elixir", "eelixir", "heex", "surface" },
capabilities = capabilities,
cmd = {
"/Users/pielov/.local/share/nvim/mason/packages/elixir-ls/language_server.sh",
},
on_attach = on_attach,
root_dir = null_ls_utils.root_pattern("mix.exs", ".git")
or vim.loop.os_homedir(),
settings = {
elixirLS = {
fetchDeps = true,
},
},
})
I can’t upload image because I’m new but LspInfo gives me
Language client log: /Users/pielov/.local/state/nvim/lsp.log
Detected filetype: elixir
1 client(s) attached to this buffer:
Client: elixirls (id: 1, bufnr: [2])
filetypes: elixir, eelixir, heex, surface
autostart: true
root directory: /Users/pielov/workspace/personal/elixir/elixirapp
cmd: /Users/pielov/.local/share/nvim/mason/packages/elixir-ls/language_server.sh
Configured servers list: elixirls, graphql, gopls, taplo, dockerls, jsonls, cssls, lua_ls, svelte, tsserver, html
I tried to download elixirls from github and cmd into it, with no luck
I tried elixirtools.nvim doesn’t work as well

I said that I am a noob but had no trouble setting it up.

Thanks for the info, I’ve been working on my config for a year or so, not sure I want to let it go. But I’ll give it a go after work and may be I’ll change my mind.

I’m super impressed by what mister folke did with LazyVim it’s working perfectly indeed.
I’m just fighting against his keymaps unfortunately.

I love the LazyVim setup vs anything else I’ve used and the keymaps are documented and easy to discover with which-key provided out of the box.
I use the nightly build of nvim because it’s proven to be more stable in practice, where with O/S provided nvim package and even stable I would still get nvim crashes.
I didn’t like the LazyVim default use of the ‘s’ keymap for search as I have too many decades of using s to delete the character under the cursor and enter insert mode.
But its is trivial to configure due to clean approach and documentation.

s is the unassuming key of choice for a bunch of plugins to override. They always say “just use cc.” Oddly I use s a lot and would always rather hit one key than two, thank-you-much! 
I’ve remapped cc to “delete line but leave it blank,” ie, a less aggressive dd, though that’s neither here nor there.
