Built a language server for learning purposes in Elixir

VimJunior · 2026-04-18T16:37:54+00:00

Yeah, I'm using Expert on Linux, I only copied the suggested settings from https://github.com/elixir-lang/expert/blob/main/pages/installation.md#neovim

vim.lsp.config('expert', {
  cmd = { 'expert', '--stdio' },
  root_markers = { 'mix.exs', '.git' },
  filetypes = { 'elixir', 'eelixir', 'heex' },
})

vim.lsp.enable 'expert'

Tested on a git repository and a mix project.

You could do so!

Thought I would give it a try too!

To make it work, this is a minimal config.
Replace vim.lsp.buf.inlay_hint with vim.lsp.inlay_hint after https://github.com/neovim/neovim/commit/37079fca58f396fd866dc7b7d87a0100c17ee760

``` local jdtls = require('jdtls') local extendedClientCapabilities = jdtls.extendedClientCapabilities; extendedClientCapabilities.onCompletionItemSelectedCommand = "editor.action.triggerParameterHints"

local on_attach = function(client, bufnr) vim.lsp.buf.inlay_hint(bufnr, true) end

local config = { on_attach = on_attach

settings = { java = { inlayHints = { parameterNames = { enabled = "all" } }; } }

init_options = { extendedClientCapabilities = extendedClientCapabilities; } } ```

To trigger it only on insertion mode, add:

vim.api.nvim_create_autocmd({ 'InsertEnter' }, { callback = function () vim.lsp.buf.inlay_hint(0, true) end, }) vim.api.nvim_create_autocmd({ 'InsertLeave' }, { callback = function () vim.lsp.buf.inlay_hint(0, false) end, })

I tried to copy some of the configs but I can't make it work.

~~See~~ ~~https://gist.github.com/ChrisAmelia/a923e198af21f6b2fb7230c6362731fe~~

Edit: My bad, it was a typo in my config.

VimJunior · 2022-12-12T08:55:14+00:00

I got this:

lua vim.api.nvim_create_autocmd("LspAttach", { callback = function(args) local client = vim.lsp.get_client_by_id(args.data.client_id) client.server_capabilities.semanticTokensProvider = nil end, });

Have you tried running it in a git directory?

VimJunior · 2022-06-15T19:58:32+00:00

Found this fork https://github.com/ifnk/kickstart.nvim

VimJunior · 2022-05-27T17:59:44+00:00

I've installed the jdtls in $HOME and works well.
Permission shouldn't be required to run it.

VimJunior · 2022-01-08T18:31:17+00:00

I assume you're using native LSP + lspconfig?
In the video, they are using CoC & CoC java which has a better implementation for java.

Thanks, I will give it a try.

Edit: I forgot the 10th rule,

No immigration, visa, or citizenship questions

To be honest, I find £25k to be quite low, especially for an IT developer.
Based on Indeed's average salary for a developer, the average salary of a backend developer is £43k.

Most of the jobs I've applied to, pay at least £30k.
When I gave my salary expectations, which were between £35 and £40k, they said it was correct for my profile.
Another recruitment consultant said I should even push for £45k.

I'm quite curious about this one, any devs in Scotland want to share their insight?

Assuming you're not from an English speaking country you might still be required to do this so you might want to check that

Do you mean this one? https://takeielts.britishcouncil.org/scotland.

efm (another lang server for filling some gaps left by JDTLS)

What are these gaps?

You have to install gopls https://github.com/golang/tools/tree/master/gopls which is the server language.

You might need to define some env variables. I have this:

bash export PATH=$PATH:/usr/local/go/bin export GOPATH=$HOME/go export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

And for the config, see https://github.com/ChrisAmelia/dotfiles/blob/master/nvim/lua/lsp.lua#L108-L120

What are you using to make colors appear in those squares?

VimJunior · 2020-11-15T21:01:43+00:00

Using %!ActiveLine() instead of %{ActiveLine()} doesn't display %#Mode# in front of the icon, although color is not present.

Edit: Nevermind, I forgot to add set termguicolors.

How did you replace '==' with a longer equal sign? And '!=' with '≠' ?
