Mouvedia · 2025-06-20T16:00:50Z

Which issue, if any, is this issue related to?

Is there anything in the PR that needs further explanation?

lib/reference/atKeywords.mjs


 /**
 * @see https://www.w3.org/TR/css-nesting-1/#conditionals
 * @type {ReadonlySet<string>}
 */
 export const nestingSupportedAtKeywords = new Set([
+	'apply',


[question] This change will seem to impact other rules than at-rule-no-deprecated. What is the reason for this addition to nestingSupportedAtKeywords?

Look further:

stylelint/lib/reference/atKeywords.mjs

Lines 60 to 65 in 4066d12

export const atKeywords = uniteSets(

deprecatedAtKeywords,

nestingSupportedAtKeywords,

pageMarginAtKeywords,

fontFeatureValueTypes,

[

It was already part of the atKeywords set hence the real regression would be to not include it back.
e.g. for at-rule-no-unknown

What is the reason for this addition to nestingSupportedAtKeywords?

That's because it can be nested in a block.
i.e. it doesn't have to be at the root ~~like for example @font-face~~

I understood the change's background. 👍🏼

So, I think we should clarify which rules are impacted by the nestingSupportedAtKeywords change in this PR. It should not be only for at-rule-no-deprecated. I'd suggest:

Add affected rules to the PR title and the changelog entry

Add test cases for the rules

If the mixin declares a @contents parameter, and the @apply rule has a block…

Declarations are further categorized as property declarations or descriptor declarations…

todo

tests

at-rule-descriptor-no-unknown

at-rule-descriptor-value-no-unknown

~~add separate changeset for at-rule-*-no-unknown~~

example for at-rule-descriptor-value-no-unknown

@mixin --qux-baz(@contents) { @supports (overflow-anchor: auto) { @font-face { @contents; } } } body { @apply --qux-baz { ascent-override: foo; } }

cf https://www.phpied.com/supports-and-font-face-troubles/

Ill add the tests but if it requires change to the rules so that the error can be detected Ill skip: true them.
i.e. the indirection that @mixin may introduce is probably not supported by those rules yet

out of scope

adding 'mixin' to nestingSupportedAtKeywords set

removing

stylelint/lib/utils/isStandardSyntaxAtRule.mjs

Lines 18 to 21 in ce56d5d

// Ignore Less mixins

if ('mixin' in atRule && atRule.mixin) {

return false;

}

fixing at-rule-*-no-unknown rules to support @contents indirection

@ybiquitous
Iv added regression tests for 2 rules.
They don't require a changeset.
I didn't add a test for property-no-unknown because I couldn't come up with one that would make sense.

ybiquitous · 2025-07-04T06:56:17Z

They don't require a changeset.

Why? If the atKeywords.mjs causes these behavior changes, should we leave that in the changelog?

Check the tests, those are regression tests.
Nothing should have changed; Ill add links to demos when Ill have time.
i.e. it's the at-rule(s) nested in the @apply that are picked up; @apply doesn't have descriptors of its own

The skipped indirection test is there to remind us to one day support @mixin.

Thank you. LGTM 👍🏼
