Columnize - format an Array as a Column-aligned String
============================================================================
In showing a long lists, sometimes one would prefer to see the value
arranged 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;
print columnize(['a','b','c','d'], {displaywidth=>4});
produces:
1 3
2 4
With numeric data
-----------------
$data_ref = [80..120];
print columnize($data, {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_verticle = 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
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:
