Information about the package, pcre2, which is shipped with common Linux distributions. The pcre2 package is designed for, Perl-compatible regular expression library.
Package Name:
pcre2
Summary:
Perl-compatible regular expression library
URL:
Description:
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. 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.
