fd043435e5 Split compile time regex flags from runtime ones 2019-01-20 22:59:28 +11:00
Maxime Coste
8c2603ab3c Support re-using the same ThreadedRegexVM for multiple iterations 
This should reduce the number of allocations as the memory allocated
for the thread stack and the saves can be re-used between runs instead
of being cleared every time.

328c497be2 Add support for named captures to the regex impl and regex highlighter 
ECMAScript is adding support for it, and it is a pretty isolated
change to do.

fb65fa60f8 Regex: take the full subject range as a parameter 
To allow more general look arounds out of the actual search range,
pass a second range (the actual subject). This allows us to remove
various flags such as PrevAvailable or NotBeginOfSubject, which are
now easy to check from the subject range.

Fixes #1902

413f880e9e Regex: Support forward and backward matching code in the same CompiledRegex 
No need to have two separate regexes to handle forward and backward
matching, just passing RegexCompileFlags::Backward will add support
for backward matching to the regex. For backward only regex, pass
RegexCompileFlags::NoForward as well to disable generation of
forward matching code.

abac6a9436 Use boost::wregex implementation and manually utf8 decode into it 
That way we get proper unicode support in regular expressions as long
as the current locale treats wchar_t as unicode codepoints.
