Hello. I was unable to find a shortcut for `.withStyledAttributes(attr) { getResourceId(it, 0) }`. Should I create a PR? None of the files below look suitable, should I create a new one?

Hello, I got this need a while ago and I made several changes on the develop branch to make that work better. Please, open an issue so I remember to add a shorthand for that.

I'll do my best to get this into a release this month. If you want, you can directly build it on top of the current `develop` branch and submit a PR.

Thanks, `resolveThemeAttribute` seems to be what I need.

By the way, is `getIndex` necessary here? <https://github.com/LouisCAD/Splitties/blob/develop/modules/resources/src/androidMain/kotlin/splitties/resources/StyledAttributes.kt#L50>

IIRC, yes, because a TypedArray can contain several data, but we only care about the resourceId in our case.
You would replace it with something else?

Short way to explain: `TypedArray.get*` accepts a `@StyleableRes` while styleable res values like `R.styleable.ViewClass_attrName` are just a 0-based int indices.

Long way. Given an array `int[] attrs { a, b, c }`, `obtainStyledAttrubites` will return a `TypedArray` which is effectively a `SparseIntArray` from `attrs.indices` to values. It is 'sparse' when some attributes are not specified and there's index-to-value-mapping.
Hence, there are to way to read styled attributes:
```
// get values specifying default ones for absent attributes
ta = obtain([a, b, c])
this.a = ta.get*(0, default);
this.b = ta.get*(1, default);
this.c = ta.get*(2, default);
```
and
```
// get values only for present attributes
for (i in 0..ta.indexCount) {
    idx = ta.getIndex(i)
    when (idx) {
        0 -&gt; this.a = ta.get*(0, whatever)
        1 -&gt; this.b = ta.get*(1, dontMind)
        2 -&gt; this.c = ta.get*(2, unused)
    }
}
```

Ooh, :google: , please, deprecate these cursed XMLs, especially styles.
