Mojo::Base get all attributes names

[Konstantin Cherednichenko]

Hello!

Is there any easy way to get all attributes names?

I tried to get it via ISA but I also got methods names... I just want to get "propA" and "propB"...

Could someone please help me?

My example:

#!/usr/bin/env perl

package A;

use Mojo::Base -base;

has propA => 123;

has propB => 'val';

sub get_props_names

{

    my $self = shift;

    my %names = ();

    {

        my $base_class = ref($self);

        no strict 'refs';

        foreach my $class ($base_class, @{"${base_class}::ISA"})

        {

            foreach my $name (keys %{"${class}::"})

            {

                $names{$name} ||= 1;

            }

        }

    };

    return [sort keys %names];

}

package main;

use Mojo::Base -strict;

use Data::Dumper;

my $obj = A->new;

say Dumper($obj->get_props_names);

Introspection capabilities are a feature of Moose.

Moose, however, adds many, many more dependencies than Mojo::Base...

To be fare, Mouse can do it as well. And Moo too (but not with support of Moose Meta Object Protocol).

If you want the introspection you're going to be expanding objects to Moose anyway so you might want to start there (though if you rarely do the introspection, using Moo for everything else may be a benefit). As for Mouse I would not recommend its usage to be combined with any other modules. https://shadow.cat/blog/matt-s-trout/moo-versus-any-moose/

Not quite sure what to call such a module, but I just wrote a proof of concept here: https://gist.github.com/jhthorsen/0ad4c5c84661588e89da910a08460e88
