Regexp::Common::whitespace.3pm

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".
