A high-performance C++ regex library and lexical analyzer generator with Unicode support. Extends Flex++ with Unicode support, indent/dedent anchors, lazy quantifiers, functions for lex and syntax error reporting and more. Seamlessly integrates with Bison and other parsers.
Matcher::find() with refactored SIMD (SSE2/AVX2/AVX512BW/NEON/AArch64) code like ugrep 6.0 and with run-time AVX2/AVX512BW detectionWhen using cmake to build, please add a missing lib/simd.cpp lib source to CMakeLists.txt:

reflex.pc and reflexmin.pc and updated configure and makefilesreflex 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.
A minor update to correct a DFA construction problem for POSIX regex lazy quantifiers matching too much in some cases

Matcher::find() with a new DFA cut algorithm to optimize match prediction speed and accuracy, see also ugrep 5.0

Minor improvements.
\X to match Unicode characters. (dot) in the documentation when used with %unicode-enabled lexers, which is a catch-all pattern e.g. to report lexical errors
