NAME

Music::Note::Role::Operators

DESCRIPTION

Role::Tiny to be applied on top Music::Note with comparison methods added and overloaded operators. Also adds a clone method.

SYNOPSIS

If you're working with a Music::Note subclass:

package Music::MyNote;
use parent 'Music::Note';
use Role::Tiny::With;
with 'Music::Note::Role::Operators';
# etc

Or if you're working in a script and just want the behaviour:

use Music::Note;
use Role::Tiny (); # Don't import R::T into current namespace for cleanliness
Role::Tiny->apply_roles_to_package('Music::Note', 'Music::Note::Role::Operators');

SUMMARY

Assuming you're working in a script:

my $note = Music::Note->new('C#');
my $other = Music::Note->new('E');

my $true = $other->gt($note);
$true = $other > $note;

$true = $note->lt($other);
$true = $note < $other;

$true = $note->eq($note->clone);
$true = $note == $note->clone;

$true = $note->gte($note->clone);
$true = $note >= $note->clone;

$true = $note->lte($note->clone);
$true = $note <= $note->clone;

CAVEAT

Don't try to do something like $note == 90>. The overloading expects a Music::Note on both sides. To perform comparisons versus note and not a note you should be doing $note->format('midi') == 90.
