Columnize - format an Array as a Column-aligned String ============================================================================ In showing long lists, sometimes one would prefer to see the values arranged and aligned in columns. Some examples include listing methods of an object, listing debugger commands, or showing a numeric array with data aligned. Setup ----- use Array::Columnize; Simple data example ------------------- print columnize(['a','b','c','d'], {displaywidth=>4}), "\n"; produces: a c b d With numeric data ----------------- my $data_ref = [80..120]; print columnize($data_ref, {ljust = 0}) ; produces: 80 83 86 89 92 95 98 101 104 107 110 113 116 119 81 84 87 90 93 96 99 102 105 108 111 114 117 120 82 85 88 91 94 97 100 103 106 109 112 115 118 while: print columnize($data_ref, {ljust = 0, arrange_vertical = 0}) ; produces: 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 With String data ---------------- @ary = qw(bibrons golden madascar leopard mourning suras tokay); print columnize(\@ary, {displaywidth => 18}); produces: bibrons mourning golden suras madascar tokay leopard puts columnize \@ary, {displaywidth => 18, colsep => ' | '}; produces: bibrons | mourning golden | suras madascar | tokay leopard Credits ------- This is adapted from my [Ruby gem of the same name](https://github.com/rocky/columnize).
