Enable biome only when biome.json is present gives error

[kjvdven]

I followed the docs to only Enable biome only when biome.json is present. And I added the following code to my config.

"lsp": {
    "biome": {
      "settings": {
        "require_config_file": true
      }
    },
}

Now I expected Biome to be disabled on projects without a config file.

But instead I get the following error;

Language server error: biome

biome.json is not found but require_config_file is true
-- stderr--

It's a limitation of zed extensions at this time. There is currently no other way of canceling the server start, except by throwing an error.

If there if a better approach, PRs are welcome.

Otherwise, if you want to actually only enable the language_server in specific projects, follow this guide:

The require_config_file option lead me to believe that it's a solution to running the extension only in projects that use Biome, so maybe it would be better to withdraw this feature until it's actually possible to automatically not run the extension in projects where it's not installed.

Is there a tracking issue for this?

I don't think so.

I did make an issue on the Zed repository.

Have you tried requireConfigFile?

Have you tried requireConfigFile?

Instead of require_config_file? It doesn't prevent Biome from running in a non-Biome project, but unlike require_config_file something different happens — the extension manages to run Biome even though Biome is not installed that workspace. With require_config_file the extension itself fails in a non-Biome project 🤔
