NAME

POSIX::Regex - OO interface for the gnu regex engine

SYNOPSIS

    use POSIX::Regex qw(:all);

    my $reg = new POSIX::Regex('a\(a\|b\)\(c\)');

    print "You win a toy!\n" if $reg->match("aac");

    if( my @m = $reg->match("abc") ) { # returns the matches
        print "entire match: ", shift @m, "\n";
        print "\tgroup match: $_\n" for @m;

    } else {
        print "No toy for you!\n";
    }

REGULAR OPTIONS

(All of the following text was plagarized without edit from 'man 3 regex'.)

If you choose to import :all then you will have the following regular options that you may optionally pass to new() (aka regcomp).

REG_ICASE

Do not differentiate case. Subsequent regexec() searches using this pattern buffer will be case insen- sitive.

REG_EXTENDED

Use POSIX Extended Regular Expression syntax when interpreting regex. If not set, POSIX Basic Regular Expression syntax is used.

REG_NEWLINE

Match-any-character operators don't match a newline.

A non-matching list ([^...]) not containing a newline does not match a newline.

Match-beginning-of-line operator (^) matches the empty string immediately after a newline, regardless of whether eflags, the execution flags of regexec(), contains REG_NOTBOL.

Match-end-of-line operator ($) matches the empty string immediately before a newline, regardless of whether eflags contains REG_NOTEOL.

REG_NOTBOL

The match-beginning-of-line operator always fails to match (but see the compilation flag REG_NEWLINE above) This flag may be used when different portions of a string are passed to regexec() and the beginning of the string should not be interpreted as the beginning of the line.

REG_NOTEOL

I am using this software in my own projects... If you find bugs, please please please let me know. :) Actually, let me know if you find it handy at all. Half the fun of releasing this stuff is knowing that people use it.

FAQ

Yes, I'm aware there's special support for alternate regular expression systems in perl 5.10.x ... let me know when people are done with perl 5.6 and 5.8 and I'll delete this from CPAN. Thanks.
