## Unreleased

## 25.13.0 (2023-11-29)
- `BorderControlDropdown`: Switches from appending state to the aria-label and adds an aria-describedBy attribute with hidden text (via display: none;, as the text will be read via focus on the button and doesn't need to announced otherwise ([#54469](https://github.com/WordPress/gutenberg/pull/54469)).

I think this function should be renamed to remove anything to do with aria. Small point but this seems to just be stripped var() from any CSS vars am I right? In which case let's

  1. Rename to better advertise it's purpose
  2. Consider extracting to a file and adding some quick unit tests.

I agree this could be made into a more generic utility function. Looks like it would be useful elsewhere too. Would you be OK with this also being a follow-up? It's starting to expand the purpose of this PR a bit.

I think we have a number of tasks that should happen as follow ups. Whilst I'm fine with them being follow ups I really think that whilst we're in the guts of this it would be good to leave the code in a better place than we found it if possible 🙏

// Leave hex values as-is. Remove the `var()` wrapper from CSS vars.
return colorValue.replace( /^var\((.+)\)$/, '$1' );

I think it would be good to extract this function and write some simple tests for the various conditionals. These are outlined in your test instructinos for the PR and it would provide a lot of confidence if they were encoded into tests:

  • No style, no color
  • Style, no color
  • Named color, no style
  • Named color, with style
  • Hex/rgba color, no style
  • Hex/rgba color, with style

I would also say it's worth refactoring it with the aim of removing the branches and conditionals but that could be done in a follow up and should not even be attempted unless we have tests in place 🙏

I agree that this should all get refactored. As I was working within the context of what was here, I didn't want to change up things too much since I only wanted to provide a better description.

It needs tidying up. I appreciate that's a big ask for this PR though. Feel free to add as a follow up task if you like.

I would help but I don't have bandwidth at this time 🙇

Does this function need to know so much? Can it not simply accept a colorValue and the consumer can pass the appropriate value. This could reduce the number of confusing conditionals.

Oh I see it needs to get the name from the object....

In which case it could accept

  • colorValue
  • colorName

That way it would not need to know about the structure of a colorObject. It can then simply compute appropriate strings based on what you provide it.

Again let's not do this refactoring without tests 🙏

What does this boolean signify? What is "style enabled"?

I'm honestly not sure -- I only renamed it to feel more accurately named and used what I needed from it. I haven't looked into it further. I do agree a refactor would be nice, but I'd prefer it as a follow-up.
