NAME ^

Orochi - A DI Container For Perl

SYNOPSIS ^

    use Orochi;

    my $c = Orochi->new();
    $c->inject_constructor('/myapp/foo' => (
        class  => 'SomeClass',
        args   => {
            bar => $c->bind_value('/myapp/bar')
        }
    );
    $c->inject_literal( '/myapp/bar' => [ 'a', 'b', 'c' ] );

BEFORE YOU USE THIS MODULE ^

WARNING: I'd rather use Bread::Board, but I have a need for a particular kind of DI NOW, and Bread::Board currently doesn't have those features. Therefore here's my version of it.

If/When Bread::Board becomes suitable for my needs, this module may simply be replaced / deleted from CPAN. You've been warned.

DESCRIPTION ^

Orochi is a simple Dependency Injection -ish system. Orochi in itself is just a big Key/Value store, with a bit of runtime lazy expansion / instantiation of objects mixed in.

USAGE WITH MOOSE CLASSES ^

This is probably how you'd want to use this module. Please see MooseX::Orochi for details

METHODS ^

new(%args)

You may specify the following arguments:

prefix

If specified, adds a prefix to the given path through mangle_path().

get($path)

Retrieves the value associated with the given $path. If the value needs to be expanded (i.e., create an object), then it will be done automatically.

mangle_path($path)

Fixes the given path, if necessary. This adds the prefix specified in the Orochi constructor, for example

inject($path, $injection_object)

Injects a Orochi::Injection object.

bind_value($path) or bind_value(\@paths)

Creates a BindValue injection, which is a lazy evaluation based on a Orochi key.

If given a list, will cascade through the given paths until one returns a defined value

inject_constructor($path => %injection_args)

Injects an object constructor. Setter injection also uses this

inject_literal($path => %injection_args)

Injects a literal value.

inject_class($class)

Injects a MooseX::Orochi based class. The class that is being injected does NOT have to use MooseX::Orochi, as long as one of the meta classes in the inheritance hierarchy does so.

inject_namespace($namespace)

Looks for modules in the given namespace, and calls inject_class on each class.
