NAME List::Extract - grep and splice combined SYNOPSIS use List::Extract 'extract'; my @keywords = qw/ foo !bar baz /; my @exclude = extract { s/^!// } @keywords; print "@keywords\n"; print "@exclude\n"; __END__ foo baz bar DESCRIPTION "List::Util" exports a "grep"-like routine called "extract" that both returns and extracts the elements that tests true. It's "grep" and "splice" combined. EXPORTED FUNCTIONS Nothing is exported by default. The :ALL tag exports everything that can be exported. $count = extract BLOCK ARRAY @extracted = extract BLOCK ARRAY Removes the elements from array for which "BLOCK" returns true. In list context the elements are returned in original order. In scalar context the number of removed elements is returned. In "BLOCK" the elements in "ARRAY" will be accessible through $_. Modifications to $_ will be preserved in the returned list, but discarded for elements left in the array. AUTHOR Johan Lodin COPYRIGHT Copyright 2007-2008 Johan Lodin. All rights reserved.
