Timothy Flynn	daf559c717	AK: Add a formatter overload for Utf16View	2021-08-10 23:07:50 +02:00
Timothy Flynn	70080feab2	AK+LibJS: Implement String.from{CharCode,CodePoint} using UTF-16 strings ... Most of String.prototype and RegExp.prototype is implemented with UTF-16 so this is to prevent extra copying of the string data.	2021-08-04 11:18:24 +02:00
Timothy Flynn	510bbcd8e0	AK+LibRegex: Add Utf16View::code_point_at and use it in RegexStringView ... The current method of iterating through the string to access a code point hurts performance quite badly for very large strings. The test262 test "RegExp/property-escapes/generated/Any.js" previously took 3 hours to complete; this one change brings it down to under 10 seconds.	2021-08-04 11:18:24 +02:00
Timothy Flynn	0e6375558d	AK+LibRegex: Partially implement case insensitive UTF-16 comparison ... This will work for ASCII code points. Unicode case folding will be needed for non-ASCII.	2021-07-23 23:06:57 +01:00
Timothy Flynn	2e45e52993	AK: Add UTF-16 helper methods required for use within LibRegex ... To be used as a RegexStringView variant, Utf16View must provide a couple more helper methods. It must also not default its assignment operators, because that implicitly deletes move/copy constructors.	2021-07-23 23:06:57 +01:00
Timothy Flynn	9b83cd1abf	AK: Add Utf16View for decoding UTF-16 strings ... Also includes a way to transcode from and to UTF-8 strings.	2021-07-22 09:10:44 +02:00
