codepoints() function

Creates a Parser that skips code points while the given predicate returns true.

This counts in unicode characters (code points), not UTF-16 code units.

This acts like starConsumed(codepoint(isMatch, [])) if expected is not set, or as plusConsumed(codepoint(isMatch, expected)) if it is, but is much more efficient than either of those combinations.

Signature:

export declare function codepoints(isMatch: (codepoint: number) => boolean, expected?: string[]): Parser<void>;

Parameters

Parameter	Type	Description
isMatch	(codepoint: number) => boolean	callback called for each codepoint, should return whether that matches
expected	string[]	(Optional) expected strings to return if the first codepoint does not match

Returns:

Parser<void>
