Version Packages (prerelease)

[github-actions[bot]]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to v4, this PR will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

v4 is currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, run changeset pre exit on v4.

style-dictionary@4.0.0-prerelease.28

Minor Changes

• 4225d78: Added the following transforms for CSS, and added them to the scss, css and less transformGroups:

  • fontFamily/css -> wraps font names with spaces in ' quotes
  • cubicBezier/css -> array value, put inside cubic-bezier() CSS function
  • strokeStyle/css/shorthand -> object value, transform to CSS shorthand
  • border/css/shorthand -> object value, transform to CSS shorthand
  • typography/css/shorthand -> object value, transform to CSS shorthand
  • transition/css/shorthand -> object value, transform to CSS shorthand
  • shadow/css/shorthand -> object value (or array of objects), transform to CSS shorthand

  The main intention here is to ensure that Style Dictionary is compliant with DTCG draft specification out of the box with regards to exporting to CSS, where object-value tokens are not supported without transforming them to shorthands (or expanding them, which is a different feature that was added in 4.0.0-prerelease.27).

Patch Changes

• a5bafac: Colors that are not recognized by tinycolor2 as valid color formats (e.g. linear-gradient(...)) are now ignored by the builtin color transforms filter functions.

I know that in CSS, linear-gradient() is not actually a <color>, it’s an <image>. I guess that it’s normal then if it’s not interpreted has a color.

I wonder if tinycolor2 should still be used as it’s a bit outdated and it does not support most recent CSS color syntaxes. I stumbled across a library called Color.js that does support newly introduced syntaxes, you might want to have a look at it.

Yeah I'm a fan of that library, please raise an issue for migrating to it to support things like oklab/oklch etc, I foresee this becoming more common and I know a couple of color nerds that would love for SD to support it in its transforms (@mikekamminga ). I won't have time for it for v4 but PRs are welcome still, seems to me like it wouldn't be a breaking change if color.js supports everything tinycolor2 does except more.

[…] seems to me like it wouldn't be a breaking change if color.js supports everything tinycolor2 does except more.

Unfortunately, I noticed that a few (non-standard) things that tinycolor2 supports are not supported by Color.js. Since the nature of Color.js makes it extensible, there could be some things done to support some of them, but I doubt that everything could be covered.

Shall we raise a separate issue for this? Can you share which things are unsupported, we can decide whether we want to add backwards compat or not, I think unprefixed hexadecimals is an example of something we could probably just decide to stop supporting, and folks can always write a custom value transform to put the # in front of such values if they really need them
