NAME
    Data::Format::Pretty::Console - Pretty-print data structure for console
    output

VERSION
    version 0.05

SYNOPSIS
    In your program:

     use Data::Format::Pretty::Console qw(format_pretty);
     ...
     print format_pretty($result);

    Some example output:

    Scalar, format_pretty("foo"):

     foo

    List, format_pretty([qw/foo bar baz qux/]):

     .------.
     | data |
     +------+
     | foo  |
     | bar  |
     | baz  |
     | qux  |
     '------'

    The same list, when program output is being piped (that is, (-t STDOUT)
    is false):

     foo
     bar
     baz
     qux

    Hash, format_pretty({foo=>"data", bar=>"format", baz=>"pretty",
    qux=>"console"}):

     .---------------.
     | key | value   |
     +-----+---------+
     | bar | format  |
     | baz | pretty  |
     | foo | data    |
     | qux | console |
     '-----+---------'

    2-dimensional array, format_pretty([ [1, 2, ""], [28, "bar", 3], ["foo",
    3, undef] ]):

     .-----------------------------.
     | column0 | column1 | column2 |
     +---------+---------+---------+
     |       1 |       2 |         |
     |      28 | bar     |       3 |
     | foo     |       3 |         |
     '---------+---------+---------'

    An array of hashrefs, such as commonly found if you use DBI's
    fetchrow_hashref() and friends, format_pretty([ {a=>1, b=>2}, {b=>2,
    c=>3}, {c=>4} ]):

     .-----------.
     | a | b | c |
     +---+---+---+
     | 1 | 2 |   |
     |   | 2 | 3 |
     |   |   | 4 |
     '---+---+---'

    Some more complex data, format_pretty({summary => "Blah...", users =>
    [{name=>"budi", domains=>["foo.com", "bar.com"], quota=>"1000"},
    {name=>"arif", domains=>["baz.com"], quota=>"2000"}], verified => 0}):

     summary:
     Blah...

     users:
     .---------------------------------.
     | domains          | name | quota |
     +------------------+------+-------+
     | foo.com, bar.com | budi |  1000 |
     | baz.com          | arif |  2000 |
     '------------------+------+-------'

     verified:
     0

    Structures which can't be handled yet will simply be output as YAML,
    format_pretty({a {b=>1}}):

     ---
     a:
       b: 1

DESCRIPTION
    This module is meant to output data structure in a "pretty" or "nice"
    format, suitable for console programs. The idea of this module is that
    for you to just merrily dump data structure to the console, and this
    module will figure out how to best display your data to the end-user.

    Currently this module tries to display the data mostly as a nice ASCII
    table (or a series of ASCII tables), and failing that, display it as
    YAML.

    This module takes piping into consideration, and will output a simpler,
    more suitable format when your user pipes your program's output into
    some other program.

    Most of the time, you don't have to configure anything. But in the
    future some formatting settings will be tweakable.

FUNCTIONS
  format_pretty($data, %opts)
    Return formatted data structure. Options:

    *   interactive => BOOL (optional, default undef)

        If set, will override interactive terminal detection (-t STDOUT).
        Simpler formatting will be done if terminal is non-interactive (e.g.
        when output is piped). Using this option will force simpler/full
        formatting.

SEE ALSO
    Modules used for formatting: Text::ASCIITable, YAML.
