What happened?

I have Biome configured and have specified files and directories to ignore, like node_modules and other paths in .gitignore. Despite this, Biome still reports checking thousands of files, which seems excessive given the actual number of files I have. Is there a way to find out which files Biome is checking and formatting? I haven't found a CLI option, such as --verbose, that shows the files being processed. How can I identify which files Biome is actually working on?

Expected result

Format only the files that is not configured to be ignored by biome

I haven't found a CLI option, such as --verbose

It's here https://biomejs.dev/reference/cli/, search for --verbose.

That's the argument you're looking for, and the new output has been added to v1.9.0, you can check the changelog for an example
