Release Notes

sass/dart-sass

v1.27.0

Compare Source

• Adds an overload to map.merge() that supports merging a nested map.

  map.merge($map1, $keys..., $map2): The $keys form a path to the nested map
  in $map1, into which $map2 gets merged.

  See [the Sass documentation][map-merge] for more details.

• Adds an overloaded map.set() function.

  map.set($map, $key, $value): Adds to or updates $map with the specified
  $key and $value.

  map.set($map, $keys..., $value): Adds to or updates a map that is nested
  within $map. The $keys form a path to the nested map in $map, into
  which $value is inserted.

  See [the Sass documentation][map-set] for more details.

• Add support for nested maps to map.get().
  For example, map.get((a: (b: (c: d))), a, b, c) would return d.
  See [the documentation][map-get] for more details.

• Add support for nested maps in map.has-key.
  For example, map.has-key((a: (b: (c: d))), a, b, c) would return true.
  See [the documentation][map-has-key] for more details.

• Add a map.deep-merge() function. This works like map.merge(), except that
  nested map values are also recursively merged. For example:

  map.deep-merge(
    (color: (primary: red, secondary: blue),
    (color: (secondary: teal)
  ) // => (color: (primary: red, secondary: teal))
  

  See [the Sass documentation][map-deep-merge] for more details.

• Add a map.deep-remove() function. This allows you to remove keys from
  nested maps by passing multiple keys. For example:

  map.deep-remove(
    (color: (primary: red, secondary: blue)),
    color, primary
  ) // => (color: (secondary: blue))
  

  See [the Sass documentation][map-deep-remove] for more details.

• Fix a bug where custom property values in plain CSS were being parsed as
  normal property values.

Dart API

• Add a Value.tryMap() function which returns the Value as a SassMap if
  it's a valid map, or null otherwise. This allows function authors to safely
  retrieve maps even if they're internally stored as empty lists, without having
  to catch exceptions from Value.assertMap().
