Regexp::Common::whitespace -- provides a regex for leading or trailing whitescape
use Regexp::Common qw /whitespace/;
while (<>) {
s/$RE{ws}{crop}//g; # Delete surrounding whitespace
}
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.
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".

Bound to be plenty.
