Zed code completion not working

Questions / Help
,
1

I really like the Zed editor but recently code completion just stopped working. I still get syntax highlighting just no code completion. Is anybody having the same issue or know what the problem might be.

The first step should always be looking at the lsp logs, which you can open via the command palette in zed.

Not exactly sure what I’m looking for in Logs but this is what my logs look like. I wonder if this line is the problem

I was getting this error too, but I did not know when it started on my mac (maybe a zed update?).

I tried to uninstall zed, compared releases of elixir-ls, etc, but I finally made it work by making the elixir-ls scripts that zed downloads to be executable. Comparing the version between VSCode and zed, I noticed that the elixir-ls release files were not marked as executable:

By running chmod +x ... things started to work again.

Nice, that solved it for me.

Also, I added the following overall config for Elixir, maybe it is useful for someone :slight_smile:

Selects the language server and configures format on save.

Most of it was taken from the zed manual

{
  "languages": {
    "Elixir": {
      "show_inline_completions": true,
      "language_servers": ["elixir-ls"],
      "format_on_save": {
        "external": {
          "command": "mix",
          "arguments": ["format", "--stdin-filename", "{buffer_path}", "-"]
        }
      }
    }
  }
}

I ran into this as well. Fwiw, I had to add this to my settings.json

"lsp": {
    "elixir-ls": {},
    ...
}
