PCRE is a widely used Unicode-compatible regular expression engine. It implements Perl5 regex syntax and semantics, some Python, .NET and Onigurama extensions. It uses just-in-time compilation, has consistent escaping rules, and allows for recursion, assertions and conditional patterns or complex subroutines and callouts, thus goes far beyond classic regular expressions.
minor feature: This is another mainly and tidying release with a few minor Enhancements. These are the main ones: 1. pcre2grep now supports the inclusion of binary zeros in patterns that are. Read from files via the -f option. 2../configure now supports --enable-jit=auto, which automatically enables JIT. if the hardware supports it. 3. In pcre2_dfa_match(), internal recursive calls no longer use the stack for. Local workspace and local ovectors. Instead, an initial block of stack is Reserved, but if this is insufficient, heap memory is used. The heap limit Parameter now applies to pcre2_dfa_match(). 4. Updated to Unicode version 11.0.0. 5. (*ACCEPT:ARG), (*FAIL:ARG), and (*COMMIT:ARG) are now supported. 6. Added support for N U+dddd , but only in Unicode mode. 7. Added support for (? ) to unset all imnsx options.
