dd85c34ae2 Use fuzzy comparisons for number operations. 
Also implement ==, which apparently didn't exist for numbers yet.
 2016-09-30 12:41:41 -07:00

dbd55e16d8 Add red(), green(), and blue(). 2016-09-30 12:41:41 -07:00
Natalie Weizenbaum
048d7cff33 Add mix(). 2016-09-30 12:41:41 -07:00
Natalie Weizenbaum
227329f9c3 Add rgba(). 
This also adds built-in function overloading. This adds some extra
layers to the default function-call logic which could be avoided by
handling overloading purely in the callbacks of functions that require
it, but it's not clear how to share logic gracefully between the perform
visitor and function helpers.
 2016-09-30 12:41:41 -07:00

5cc5bf1914 Add rgb(). 2016-09-30 12:41:41 -07:00

bacc1c4529 Unify strings and identifiers. 
The separation makes sense conceptually, but it would make string
functions a lot harder to write.
 2016-09-30 12:41:41 -07:00

9ac48fbc05 Add support for binary operations. 2016-09-30 12:41:41 -07:00
Natalie Weizenbaum
7fb7804a52 Refactor list parsing. 
Moving all list parsing into a single method with a giant switch will
make it possible to parse binary operations there in the future.

Natalie Weizenbaum
3a2b7ca9df Split the parser up. 
There are now separate parsers for selectors and at-root queries, since
those are parsed independently of the main stylesheet. The Parser class
contains utilities that are useful across different parsers.

Natalie Weizenbaum
673db13d51 Move emptiness-checking to the serializer. 
We can't actually know if a rule will be empty until we've evaluated the
entire stylesheet, since it might contain a placeholder that may or may
not be extended.

of the perform visitor.
