Array::Columnize - arrange list data in columns.

SYNOPSIS

    use Array::Columnize;
    print columnize($array_ref, $optional_hash_or_hash_ref);

DESCRIPTION

OPTIONS

displaywidth

the line display width used in calculating how to align columns

colfmt

What format specifier to use in sprintf to stringify list entries. The default is none.

colsep

the column separator

lineprefix
linesuffix
termadjust
arrange_array
ladjust

EXAMPLES

Simple data example

    print columnize(['a','b','c','d'], {displaywidth=>4});

produces:

    a  c
    b  d

With numeric data

    my $array_ref = [80..120];
    print columnize($array_ref, {ljust => 0}) ;

produces:

    80  83  86  89  92  95   98  101  104  107  110  113  116  119

    82  85  88  91  94  97  100  103  106  109  112  115  118

while:

    print columnize($array_ref, {ljust => 0, arrange_vertical => 0}) ;

produces:

     80   81   82   83   84   85   86   87   88   89

    120

And

    my $array_ref = [1..30];
    print columnize($array_ref,
                    {arrange_array => 1, ljust => 0, displaywidth => 70});

produces:
