…aceOrSolidus (facebook#48828) Summary: 1. Rename `CSSComponentValueDelimeter` to `CSSDelimeter` bc the names are getting way too long. 2. Make the distinction between `Whitespace` and `OptionalWhitespace`. Note that for property values, and function blocks, the value parser will already remove trailing/leading whitespace, but it's weird that whitespace unlike others was not required to be present 3. Add `CSSDelimeter::CommaOrWhitespaceOrSolidus` for simpler parsing in the common pattern of alpha values, and move CSSColor function parsing to use that Changelog: [Internal] Reviewed By: lenaic Differential Revision: D68461968
Summary: In the last diff I mixed and matched `<legacy-rgb-syntax>` and `<modern-rgb-syntax>` a bit to keep compatiblity with `normalze-color`. Spec noncompliant values have only been allowed since facebook#34600 with the main issue being that legacy syntax rgb functions are allowed to use the `/` based alpha syntax, and commas can be mixed with whitespace. This seems like an exceedingly rare real-world scenario (there are currently zero usages of slash syntax in RKJSModules validated by `rgb\([^\)]*/`), so I'm going to instead just follow the spec for more sanity. Another bit that I missed was that modern RGB functions allow individual components to be `<percentage>` or `<number>` compared to legacy functions which only allow the full function to accept one or the other (`normalize-color` doesn't support `<percentage>` at all), so I fixed that as well. I started sharing a little bit more of the logic here, to make things more readable when adding more functions. Changelog: [Internal] Reviewed By: javache Differential Revision: D68468275
