// A relatively straight-forward predictive parser.
|

// There is no tokenization/lexing stage, the input is parsed
|
||
// in one sweep.
|
||
//
|
||
// To make the parser fast enough to run in the browser, several
|
||
// optimization had to be made:
|
||
//
|
||
// - Matching and slicing on a huge input is often cause of slowdowns.
|
||
// The solution is to chunkify the input into smaller strings.
|
||
// The chunks are stored in the `chunks` var,
|
||
// `j` holds the current chunk index, and `currentPos` holds
|
||
// the index of the current chunk in relation to `input`.
|
||
// This gives us an almost 4x speed-up.
|
||
//
|
||
// - In many cases, we don't need to match individual tokens;
|
||
// for example, if a value doesn't hold any variables, operations
|
||
// or dynamic references, the parser can effectively 'skip' it,
|
||
// treating it as a literal.
|
||
// An example would be '1px solid #000' - which evaluates to itself,
|
||
// we don't need to know what the individual components are.
|
||
// The drawback, of course is that you don't get the benefits of
|
||
// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
|
||
// and a smaller speed-up in the code-gen.
|
||
//
|
||
//
|
||
// Token matching is done with the `$` function, which either takes
|
||
// a terminal string or regexp, or a non-terminal function to call.
|
||
// It also takes care of moving all the indices forwards.
