# Regexp::Common::whitespace - phpMan

## 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".
