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:

set(lib_sources
  lib/simd.cpp

reflex v4.2.1

What's new?

• minor update to adjust the current input pointer by one when not matching anything

reflex v4.2.0

What's new?

• new pkg-config files reflex.pc and reflexmin.pc and updated configure and makefiles
• minor update of reflex command option -p to permit empty lexer specifications #202 (*)

*) performance profiling statistics are collected for lexer rules execution, i.e. when no rules are specified no meaningful performance statistics are collected.

reflex v4.1.2

What's new?

• updated configure scripts with improved cross compilation and improved SIMD CPU extension detection
• cast negative ctype function arguments (problem detected on NetBSD 10 #198)
• verified on ARM6 (Debian), ARM7 (Debian), AArch64 (MacOS M1, Android termux), x86_64 (MacOS Intel, Cygwin, Debian)

reflex v4.1.1

What's new?

A minor update to correct a DFA construction problem for POSIX regex lazy quantifiers matching too much in some cases

reflex v4.1.0

What's new?

• improved lazy quantifiers for POSIX regex lazy matching in linear time (i.e. no backtracking) using an advanced DFA transformation algorithm first introduced in RE/flex in 2016 and extended in this release
• add option --[no]yypanic for Flex++ compatibility
