NAME List::Permute::Limit - Permute all items list, with limit of number of items per result item VERSION This document describes version 0.001 of List::Permute::Limit (from Perl distribution List-Permute-Limit), released on 2019-12-31. SYNOPSIS use List::Permute::Limit qw(permute_iter permute); # iterator interface my $iter = permute_iter(items=>["zero","one","two","three"], nitems=>2); while (my $ary = $iter->()) { print "@{$ary}\n"; } will print: zero zero zero one zero two zero three one zero one one one two one three two zero two one two two two three three zero three one three two three three To return the whole permutation in a list: # array interface my @res = permute(items=>["zero","one","two","three"], nitems=>2); # => ( # ["zero", "zero"], # ["zero", "one"], # ["zero", "two"], # ["zero", "three"], # ["one", "zero"], # ["one", "one"], # ["one", "two"], # ["one", "three"], # ["two", "zero"], # ["two", "one"], # ["two", "two"], # ["two", "three"], # ["three", "zero"], # ["three", "one"], # ["three", "two"], # ["three", "three"], # ) DESCRIPTION This is just yet another list permutor module, with a limit on the number of items per result. FUNCTIONS permute Usage: permute(%args) -> any This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * items* => *array* * nitems => *posint* Number of items of each permutation result. Return value: (any) permute_iter Usage: permute_iter(%args) -> any This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * items* => *array* * nitems => *posint* Number of items of each permutation result.
