Configure Helix to use ElixirLS

My favorite editor is Zed, but I also like to have Helix configured for quick edits directly in the terminal.

Like Zed, Helix is written in Rust which makes it fast. Helix is a post modern text editor that runs inside the terminal. It uses the VIM philosophy, but changes a few things.

It comes pre-configured with a few things, like syntax highlighting. But it needs some work (minimal) to add things like a language server for your favorite language.

I use Elixir, so I want to configure ElixirLS to work with Helix.

1. Check if hx already knows where ElixirLS is
   

   Configured language server: elixir-ls
   Binary for language server: /path/to/elixir-ls/elixir-ls
   Configured debug adapter: None
   Highlight queries: ✓
   Textobject queries: ✓
   Indent queries: ✓
   

2. If it doesn't know about it (it will report it can't find the binary), or you want a very specific version of ElixirLS, download the latest release from GitHub.

3. Unzip the archive

4. Locate language-server.sh and rename it to elixir-ls
   

   mv /path/to/language-server.sh /path/to/elixir-ls
   

5. Move the whole ElixirLS folder to a preferred path

6. Add the following to your .zshrc
   

   export="/path/to/elixir-ls:$PATH"
   

Now if you run hx --health elixir it should be able to find the server. Helix expects elixir-ls to be in the PATH, that's why we needed to rename language-server.sh.

If you are looking for more information or ways to customize language servers, you can check Helix's documentation.
