NAME

Regexp::Common::whitespace -- provides a regex for leading or trailing whitescape

SYNOPSIS

    use Regexp::Common qw /whitespace/;

    while (<>) {
        s/$RE{ws}{crop}//g;           # Delete surrounding whitespace
    }

DESCRIPTION

Please consult the manual of Regexp::Common for a general description of the works of this interface.

Do not use this module directly, but load it via Regexp::Common.

$RE{ws}{crop}

Returns a pattern that identifies leading or trailing whitespace.

For example:

        $str =~ s/$RE{ws}{crop}//g;     # Delete surrounding whitespace

The call:

        $RE{ws}{crop}->subs($str);

is optimized (but probably still slower than doing the s///g explicitly).

This pattern does not capture under
 "-keep"
.
