https://github.com/elixir-lsp/elixir-ls
`elixir-ls` can be installed via `:LspInstall elixirls` or by yourself by following the instructions [here](https://github.com/elixir-lsp/elixir-ls#building-and-running).
This language server does not provide a global binary, but must be installed manually. The command `:LspInstaller elixirls` makes an attempt at installing the binary by
Fetching the elixir-ls repository from GitHub, compiling it and then installing it.
```lua
require'nvim_lsp'.elixirls.setup{
-- Unix
cmd = { "path/to/language_server.sh" };
-- Windows
cmd = { "path/to/language_server.bat" };
...
}
```
