I dont seem to be able to have the lsp working. I installed the elixir-ls and I can see it working if I type ! elixir-ls in claude code prompt but, when I ask claude to test the lsp while I am in an elixir project, I get No LSP server available for file type: .ex
I am lost and Claude seem to not understand what is wrong too :smiley:
I am on the lastest Claude Code (2.0.74)

Great, maybe we need to contribute Ash related ones

I personally have found the post edit and pre commit hooks useful for running mix ash.codegen: claude-marketplace-elixir/plugins/ash/README.md at main · bradleygolden/claude-marketplace-elixir · GitHub

And great project, ty for sharing!

Tried to use it, couldn’t get it to work, claude tried to help, run in circles, but nothing helped.

● Good news — expert IS running (Claude Code started it). It’s a BEAM process. And the manual test shows it does accept --stdio. The issue is likely that expert takes a while to initialize (compiling/indexing), and the LSP tool times out.

● Bash(which expert && expert --version 2>&1)
