Revision history for Perl extension MooseX-AttributeHelpers
+0.06
+ * MooseX::AttributeHelpers::Base
+ - added the &remove_accessors method to comply with the
+ Class::MOP::Attribute interface
+ - added test for this
+ - the &install_accessors method now also properly assocaites
+ the methods with the attribute, so they are accessible via
+ introspection now.

- update Class::MOP dependency
- - hide the Moose::Meta::Attribute::Custom::* package

declarations from search.cpan.org (when did they change
things to start seeing these?? *sigh*)
* MooseX::AttributeHelpers::Base
- changing this to use the new Class::MOP::Attribute
reader and write method ref stuff.
- - fixed this to use find_or_create_type_constraint
+ - fixed this to use find_or_create_type_constraint
instead of trying to parse stuff on our own.

+ MooseX::AttributeHelpers::Collection::ImmutableHash
+ MooseX::AttributeHelpers::Collection::Bag
- added these two new collection types
- added method provider roles for them
- added tests for them

* MooseX::AttributeHelpers::MethodProvider::Hash
- this is now composed from the ImmutableHash
method provider

* MooseX::AttributeHelpers::Counter
- now provides default attribute options for 'is',
'isa', 'provides', and 'default' if not specified.
-
+
* MooseX::AttributeHelpers::Base
- added attribute $name to the params passed to
process_options_or_provides(), which gives us more
flexibility when writing additional helpers
- removed check for 'provides' and 'isa' attr
options before _process_options. It should be
- called always.
