From: Nick Woolley Date: Fri, 27 Mar 2009 20:50:08 +0000 (+0000) Subject: Implemented Mouse::Role->does; modified Mouse::Meta::Class->initialise X-Git-Tag: 0.20~59 X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=gitmo%2FMouse.git;a=commitdiff_plain;h=6719984210754e8d012ae678536f194c35000823 Implemented Mouse::Role->does; modified Mouse::Meta::Class->initialise to allow use as an instance method to make this work. Implemented Mouse::Role::override and ::super. To do this, added Mouse::Meta::Class->add_override_method_modifier, Implemented throwing stubs for Mouse::Role::augment and ::inner, as in Moose::Role. Added 020_roles/ tests from latest respoitory version of Moose. Modified some tests to pass; the rest have been moved to 020_roles/failing for later examination. Implemented Mouse::Role->does_role, from Moose. This does not yet quite seem to pass all the tests it should, not sure why. Fixed bug in Mouse::Meta::Role->apply and ->combine_apply, so that 030_roles/002_role.t tests pass. Implemented ->version, ->authority and ->identifier in Mouse/Utils.pm, imported for use as methods by Mouse::Meta::Role and Mouse::Meta::Class. Tweaked .gitignore. "make test" passes all tests, including the new ones. --- diff --git a/.gitignore b/.gitignore index c2fe79f..858eae4 100644 --- a/.gitignore +++ b/.gitignore @@ -1,10 +1,11 @@ META.yml Makefile -blib/ -inc/ +blib/* +inc/* *.sw[po] pm_to_blib MANIFEST MANIFEST.bak SIGNATURE lib/Mouse/Tiny.pm +*~ \ No newline at end of file diff --git a/lib/Mouse/Meta/Class.pm b/lib/Mouse/Meta/Class.pm index 8e89567..0eb22ec 100644 --- a/lib/Mouse/Meta/Class.pm +++ b/lib/Mouse/Meta/Class.pm @@ -5,7 +5,7 @@ use warnings; use Mouse::Meta::Method::Constructor; use Mouse::Meta::Method::Destructor; use Scalar::Util qw/blessed/; -use Mouse::Util qw/get_linear_isa/; +use Mouse::Util qw/get_linear_isa version authority identifier/; use Carp 'confess'; do { @@ -20,8 +20,9 @@ do { } sub initialize { - my $class = shift; - my $name = shift; + my $class = blessed($_[0]) || $_[0]; + my $name = $_[1]; + $METACLASS_CACHE{$name} = $class->new(name => $name) if !exists($METACLASS_CACHE{$name}); return $METACLASS_CACHE{$name}; @@ -76,7 +77,7 @@ my $get_methods_for_class = sub { no strict 'refs'; # Get all the CODE symbol table entries my @functions = - grep !/^(?:has|with|around|before|after|blessed|extends|confess|override|super)$/, + grep !/^(?:has|with|around|before|after|augment|inner|blessed|extends|confess|override|super)$/, grep { defined &{"${name}::$_"} } keys %{"${name}::"}; push @functions, keys %{$self->{'methods'}->{$name}} if $self; @@ -260,6 +261,22 @@ sub add_after_method_modifier { $self->_install_modifier( $self->name, 'after', $name, $code ); } +sub add_override_method_modifier { + my ($self, $name, $code) = @_; + + my $pkg = $self->name; + my $method = "${pkg}::${name}"; + + # Class::Method::Modifiers won't do this for us, so do it ourselves + + my $body = $pkg->can($name) + or confess "You cannot override '$method' because it has no super method"; + + no strict 'refs'; + *$method = sub { $code->($pkg, $body, @_) }; +} + + sub roles { $_[0]->{roles} } sub does_role { diff --git a/lib/Mouse/Meta/Role.pm b/lib/Mouse/Meta/Role.pm index e82690d..f7ebd21 100644 --- a/lib/Mouse/Meta/Role.pm +++ b/lib/Mouse/Meta/Role.pm @@ -2,7 +2,7 @@ package Mouse::Meta::Role; use strict; use warnings; use Carp 'confess'; -use Mouse::Util; +use Mouse::Util qw(version authority identifier); do { my %METACLASS_CACHE; @@ -43,6 +43,8 @@ sub add_required_methods { push @{$self->{required_methods}}, @methods; } + + sub add_attribute { my $self = shift; my $name = shift; @@ -88,16 +90,18 @@ sub apply { for my $name ($self->get_method_list) { next if $name eq 'meta'; - if ($classname->can($name)) { + my $class_function = "${classname}::${name}"; + my $role_function = "${selfname}::${name}"; + if (defined &$class_function) { # XXX what's Moose's behavior?
