NAME

List::Generator - provides functions for generating lists

VERSION

version 0.976

SYNOPSIS

this module is an alias for List::Gen. it is the same as List::Gen in every way.

            

              
              
use List::Generator;
my $range = <1 .. 1_000_000_000 by 3>;
my $squares = gen {$_ ** 2} <1..>;
my $fib = <0, 1, *+* ...>;
say "@$fib[0 .. 10]"; # 0 1 1 2 3 5 8 13 21 34 55
list(1 .. 5)->map('*2')->say; # 2 4 6 8 10
<1..>->zip('.' => <a..>)->say(5); # 1a 2b 3c 4d 5e
            
          

each line below prints '1 9 25 49 81' :

            

              
              
functions:           (gen {$_**2} filter {$_ % 2} 1, 10)->say;
list comprehensions: <**2 for 1 .. 10 if odd>->say;
dwimmy methods:      <1..10>->grep('odd')->map('**2')->say;
normal methods:      range(1, 10)->grep(sub {$_%2})->map(sub {$_**2})->say;
