What happened?

The following pattern ignores all JSON/JSONC files in the repo, but not biome.jsonc. It's impossible to ignore that file, no matter what I do.

  "files": {
    "ignore": ["*.json*"]
  },

Expected result

It should follow the config and ignore that file.

Code of Conduct

[ematipico]

Can you please be more precise about the semantics of "ignore"? Biome needs to read it, and provide diagnostics if it's broken.

Failing to have a valid configuration is vital, and Biome should not function if the configuration isn't correct

[hyperknot]

I don't want to format it, I'm running biome check --write --unsafe at the root of my repo.

[arendjr]

For this use case, doesn’t it make more sense to move the ignore into the formatter section? Not sure if that works today though.

[hyperknot]

I don't understand though why is the "files-being-formatted" related to the self-config of the app. I think the two has nothing to do with each other. The self-config shouldn't receive special treatment.

[dyc3]

Without getting too into the internals, "Ignoring" a file in biome means that we don't process the file, and therefore don't emit diagnostics for errors in that file, whether those are for parsing, formatting, or linting. However, we must process the config file in order to read the configuration. By default, "processing" includes formatting.

You should be able to add an override that disables the formatter.

"overrides": [
    {
        "include": ["biome.jsonc"],
        "formatter": {
            "enabled": false
        },
    }
]
