программа для тестирования регулярных выражений, совместимых с Perl (a program for testing Perl-compatible regular expressions.)
Синопсис (Synopsis)
pcretest [options] [input file [output file]]
pcretest was written as a test program for the PCRE regular
expression library itself, but it can also be used for
experimenting with regular expressions. This document describes
the features of the test program; for details of the regular
expressions themselves, see the pcrepattern documentation. For
details of the PCRE library function calls and their options, see
the pcreapi , pcre16 and pcre32 documentation.
The input for pcretest is a sequence of regular expression
patterns and strings to be matched, as described below. The
output shows the result of each match. Options on the command
line and the patterns control PCRE options and exactly what is
output.
As PCRE has evolved, it has acquired many different features, and
as a result, pcretest now has rather a lot of obscure options for
testing every possible feature. Some of these options are
specifically designed for use in conjunction with the test script
and data files that are distributed as part of PCRE, and are
unlikely to be of use otherwise. They are all documented here,
but without much justification.
