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}


$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".

  The whole world understands RCS/CVS version numbers, that 1.9 is an
  older version than 1.10. Except CPAN. Curse the idiot(s) who think
  that version numbers are floats (in which universe do floats have
  more than one decimal dot?).
  Everything is bumped to version 2.100 because CPAN couldn't deal
  with the fact one file had version 1.10.
