how is include/ignore supossed to work?

[tcoopman]

Let's say I have a structure like this:

.
- a/
- b/
- c/
- package.json
- biome.json

I'm using yarn workspaces. There are a lot more folders than this example.
I'm trying to get biome to only run on a and b.
Biome version: 1.5.0

What works excluding all folders with files.ignore

What doesn't work: setting files.include to : ["a", "b"]
(setting formatter.include also doesn't work)

Here is the rest of my biome.json without any include/ignore rules

{
  "$schema": "https://biomejs.dev/schemas/1.5.0/schema.json",
  "organizeImports": {
    "enabled": true
  },
  "files": {
    "ignoreUnknown": true
  },
  "linter": {
    "enabled": true,
    "rules": {
      "recommended": true
    }
  },
  "formatter": {
    "indentStyle": "space",
    "indentWidth": 2
  }
}

We use globset crate, so we use its logic for composing globs:

[tcoopman]

This new release seems to have fixed the issue. But given that ignore overrides include completely, I'm not sure how to write a rule for:

- a
- - 1
- - 2
- - 3
- - 4

So I want to write an include rule that says: format everything in a except a/3 for example.

[tcoopman]

The reason for the include rule is that the exclude rule becomes quite long...

[ematipico]

I think something like this:

{
	"files": {
		"ignore": ["a/3/**"],
		"include": ["a/**"]
	}
}

[tcoopman]

I don't think that works. I think I've tried that and it didn't work.
Anyway the docs also say:

When both include and ignore are specified, ignore takes precedence over include

I interpret that as if you have any ignore, your include rules are completely ignored.
And that's how it seems to work as well.

[ematipico]

Oh yeah, you're right. Probably we should change the logic in V2.

Compute ignore first, and include second.

[Conaclos]

In the last release (1.5.2), both approaches should work. You

You can even include files and then ignore some of them.
For example, the following example, include all file sunder a/, but files under a/3/.

{
	"files": {
		"include": ["a/"],
		"ignore": ["a/3/"]
	}
}

Please, lets me know if this satisfies your request :)

[Conaclos]

The issue should now be solved.
