grass/CHANGELOG.md

• hide unimplemented command line flags
• implement CLI options for --quiet, --load-path (#22 by @JosephLing), --no-charset, --stdin, and --no-unicode
• use unicode characters in error messages by default
• allow comma separated @import statements (#23 by @JosephLing)
• implement and correctly parse !optional in @extend
• lazily evaluate !default variable values
• disallow interpolation in mixin and function names
• improve parsing for @supports and unknown at-rules

Breaking

• functions now take an Options struct

0.9.5

A small release fixing potential build issues and improving documentation.

This release is not published to NPM due to a bug in wasm-pack.

0.9.4

• implement @keyframes
• don't strip newlines following comments in selectors

0.9.3

• fix parsing bugs for empty bracketed lists
• partially implement inverse units
• remove all remaining todo!()s from binary and unary ops
• parse keywords case sensitively
• various optimizations that make bulma about 6x faster to compile

0.9.2

• implement builtin functions min and max
• bugfixes for @extend and selector-unify
• allow @content to take arguments
• bugfixes for @content, for example it will no longer infinitely recurse for chained mixins
• better support queries in @media
• bugfixes for @media
• add support for splats, e.g. rgba([1, 2, 3, 4]...)
• resolve a number of parsing bugs for @for, variable declarations, selectors, and maps
• completely rewrite how styles are evaluated, allowing short circuiting of values like false and unit(foo) and if(true, foo, unit(foo)

0.9.1

This release is largely focused on @extend, but it also resolves some regressions resulting from the new parser.

• implement @extend
• properly document new API
• MVP implementation of @supports
• fix regression in which @at-root would panic when placed after a ruleset
• fix regression related to @mixin and @function scoping when combined with outer, local variables
• remove most remaining unwraps that could result in a panic

0.9.0

This release is focused on setting up the groundwork for implementing @extend as well as being able to compile Bootstrap.

• implement all builtin selector functions
  • selector-append
  • selector-extend
  • selector-nest
  • selector-parse
  • selector-replace
  • selector-unify
  • simple-selectors
  • is-superselector
• implement builtin function content-exists
• allow @import, @warn, and @debug in all contexts, such as inside @mixin
• refactor control flow evaluation, resolving some issues blocking Bootstrap

Breaking Changes

• remove the StyleSheet struct in favor of freestanding functions, from_string and from_path

0.8.3

This release is largely focused on performance and robustness

• implement smallint optimization for numbers, making some benchmarks 50% faster
• remove bimap as a dependency for storing named colors in favor of an ad hoc, more specialized data structure
• remove dozens of panics on malformed input
• use beef::Cow instead of std::borrow::Cow
• increase code coverage to 80%

0.8.2

This release contains significant (>10x) improvements for WASM speed. Performance is now comparable to libsass bindings with node-sass as well as dart-sass with dart2js. It is, however, roughly 4x slower than native grass.
