# NAME
re::engine::PCRE2 - PCRE2 regular expression engine with jit
# SYNOPSIS
use re::engine::PCRE2;
if ("Hello, world" =~ /(?<=Hello|Hi), (world)/) {
print "Greetings, $1!";
}
# DESCRIPTION
Replaces perl's regex engine in a given lexical scope with PCRE2
regular expressions provided by libpcre2-8.
This provides jit support and faster matching, but may fail in
cornercases.
Note that some packaged libpcre2-8 libraries do not enable the jit
compiler. `cmake -DPCRE2_SUPPORT_JIT=ON`
PCRE2 then silently falls back to the normal PCRE2 compiler and matcher.
Check with:
perl -Mre::engine::PCRE2 -e'print re::engine::PCRE2::JIT'
perl -Mre::engine::PCRE2 -e'print re::engine::PCRE2::JITTARGET'
