reflex v5.1

What's new?

• usability improvements
• update the regex converter of reflex::Matcher (and reflex::FuzzyMatcher by inheritance) to accept \0 as NUL #216
• appease compiler warnings #217

reflex v5.0.1

Minor update to fix compilation issue #214.

reflex v5.0

What's new?

• faster SIMD regex search methods, see also the ugrep project update
• improved anchor and word boundary matching speed and support
• new std::string_view strview() matcher method

reflex v4.5.0

What's new?

Minor speed and usability improvements.

reflex v4.4.0

What's new?

• upgraded reflex::Matcher and reflex::FuzzyMatcher to respect Unicode word boundaries instead of only ASCII \<, \>, \b, \B
• upgraded regex Unicode converters to support Unicode [::] character classes instead of only ASCII [[:alpha:]] etc., note that \p{Class} always supports Unicode (a regex converter is invoked with reflex::Matcher::convert(...) to support Unicode and other syntax constructs that the lower-level reflex::Matcher does not support, see documentation)
• improved FSM code generation

reflex v4.3.0

What's new?

• faster Matcher::find() with refactored SIMD (SSE2/AVX2/AVX512BW/NEON/AArch64) code like ugrep 6.0 and with run-time AVX2/AVX512BW detection
• increased default internal input buffer size

Note

When using cmake to build, please add a missing lib/simd.cpp lib source to CMakeLists.txt:
