Adding values and functions to custom data

[romainmenke]

Adding custom values and functions to custom data would make it easier and more maintainable to have a richer editor experience for these tokens.

For PostCSS specifically it is not possible to create a general purpose language extension that covers all possible custom additions. Every user's collection of plugins is a bit different.

Plugin authors could also publish relevant custom data for their PostCSS plugins.

This can also act as an escape hatch for newer language features like oklch(0 0 0).

.foo {
  color: my-custom-color-ident;
  color: my-custom-color-function(0 0 0);
