6 MooseX::Declare::Syntax::NamespaceHandling - Handle namespaced blocks
7
9 version 0.43
10
12 Allows the implementation of namespaced blocks like the role and class
13 keyword handlers.
14
15 Namespaces are automatically nested. Meaning that, for example, a
16 "class Bar" declaration inside another "class Foo" block gives the
17 inner one actually the name "Foo::Bar".
18
20 parse
21 Any Object->parse (Object $context)
22
23 This is the main handling routine for namespaces. It will remove the
24 namespace name and its options. If the handler was invoked without a
25 name, options or a following block, it is assumed that this is an
26 instance of an autoquoted bareword like "class => "Foo"".
27
28 The return value of the "parse" method is also the value that is
29 returned to the user of the keyword.

35
37 handle_missing_block
38 Object->handle_missing_block (Object $context, Str $body, %args)
39
40 This must be implemented to decide what to do in case the statement is
41 terminated rather than followed by a block. It will receive the context
42 object, the produced code that needs to be injected, and all the
43 arguments that were passed to the call to "inject_code_parts" in
44 MooseX::Declare::Context.
45
46 The return value will be ignored.
47
49 add_namespace_customizations
50 add_optional_customizations
51 Object->add_namespace_customizations (Object $context, Str $package, HashRef $options)
52 Object->add_optional_customizations (Object $context, Str $package, HashRef $options)
53
54 These will be called (in this order) by the "parse" method. They allow
55 specific hooks to attach before/after/around the customizations for the
56 namespace and the provided options that are not attached to the
57 namespace directly.
58
59 While this distinction might seem superficial, we advise library
60 developers facilitating this role to follow the precedent. This ensures
61 that when another component needs to tie between the namespace and any
62 additional customizations everything will run in the correct order. An
63 example of this separation would be
64
65 class Foo is mutable ...
66
67 being an option of the namespace generation, while
68
69 class Foo with Bar ...
70
71 is an additional optional customization.
72
73 handle_post_parsing
74 Object->handle_post_parsing (Object $context, Str $package, Str | Object $name)
75
76 Allows for additional modifications to the namespace after everything
77 else has been done. It will receive the context, the fully qualified
78 package name, and either a string with the name that was specified
79 (might not be fully qualified, since namespaces can be nested) or the
80 anonymous metaclass instance if no name was specified.
81
82 The return value of this method will be the value returned to the user
83 of the keyword. If you always return the $package argument like this:
84
85 sub handle_post_parsing {
86 my ($self, $context, $package, $name) = @_;
87 return $package;
88 }
89
90 and set this up in a "foo" keyword handler, you can use it like this:
91
92 foo Cthulhu {
93
94 my $fhtagn = foo Fhtagn { }
95 my $anon = foo { };
96
97 say $fhtagn; # Cthulhu::Fhtagn
98 say $anon; # some autogenerated package name
99 }
100
101 make_anon_metaclass
102 Class::MOP::Class Object->make_anon_metaclass ()
103
104 This method should be overridden if you want to provide anonymous
105 namespaces.
106
107 It does not receive any arguments for customization of the metaclass,
108 because the configuration and customization will be done by
109 MooseX::Declare in the package of the generated class in the same way
110 as in those that have specified names. This way ensures that anonymous
111 and named namespaces are always handled equally.
112
113 If you do not extend this method (it will return nothing by default),
114 an error will be thrown when a user attempts to declare an anonymous
115 namespace.
