Summary [Yarr] Improve processing of [\s\S] character classes
Michael Saboff
Reported 2024-11-12 11:43:00 PST
The character class [\s\S], which is all white space and non-white space characters is used in lieu of ‘.’ (any character). Many developers use [\s\S] instead of ’.’ because the ‘.’ any character does not include line terminators unless the dot all ’s’ flag is added to the regex. The character class [\s\S] matches any character regardless of flags added to the expression. The current YARR processing of [\s\S] "any character' character classes is suboptimal. We only need to read a subject string character. Instead, we currently check the read character for various values.
