New Perl Compatible Regular Expression Library - utilities

This is PCRE2, the new implementation of PCRE, a library of functions to support regular expressions whose syntax and semantics are as close as possible to those of the Perl 5 language. New projects should use this library in preference to the older library, confusingly called pcre3 in Debian. This package contains the utilities pcre2grep (like grep with PCRE) and pcre2test (a test program for the library, but also useful for experimenting with regular expressions). Both programs are also useful examples of programming with libpcre2.

pcre2

PCRE2 is a re-working of the original PCRE (Perl-compatible

regular expression) library to provide an entirely new API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. There are no C++ wrappers. This package provides support for strings in 8-bit and UTF-8 encodings. Install pcre2-utf16 or pcre2-utf32 packages for the other ones. The distribution does contain a set of C wrapper functions for the 8-bit library that are based on the POSIX regular expression API (see the pcre2posix man page). These can be found in a library called libpcre2posix. Note that this just provides a POSIX calling interface to PCRE2; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE2's facilities.
