|

|
+// 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.

|

|
+ // Ruleset -> Declaration -> Value -> Expression -> Entity
|
|

|

|

|

|
+ // color: #fff;

+ //
|

|
|
|
+ //
|
|
|
+ // Ruleset (Selector '.class', [
|
|
|
+ // Declaration ("color", Value ([Expression [Color #fff]]))
|

+ // In general, most rules will try to parse a token with the `$re()` function, and if the return
|
|
|
+ // value is truly, will return a new node, of the relevant type. Sometimes, we need to check
