NAME

Attribute::Method::Tags - Attribute interface for adding tags to methods.

SYNOPSIS

 package Bleh;

 # using Attribute::Method::Tags will add to callers ISA
 use Attribute::Method::Tags;

 sub foo : Tags( quick fast loose ) {
     ...
 }

 sub bar : Tags( quick ) {
     ...
 }

 # can use Attribute::Method::Tags::Registry to query tags on all classes.

DESCRIPTION

This class permits adding arbitrary tags to methods, via an attribute interface. The tags can later be queried via the Attribute::Method::Tags::Registry class.

Note that since attributes only work via inheritance, 'use'ing this class will add it to the @ISA of the composing class.

ATTRIBUTES

The only usage of this class is through the 'Tags' attribute against subs. A list of arbitrary alphanumeric tags can be given as parameters, seperated by whitespace. Each of the tags will be added to the registry contained in Attribute::Method::Tags::Registry, and can be queried via that class.

CAVEATS

As attributes are handled at compilation time, actions such as requiring classes or eval'ing code during runtime won't play well when used with attributes. This can be gotten around by doing such actions with a BEGIN block. If this isn't possible, a workaround is to define your dynamic methods without any attributes, the use Attribute::Method::Tags::Registry 'add' method to explicitly tag the method.

SEE ALSO

Attributes::Method::Tags::Registry

Registry class, that permits querying of all tags across all packages/methods.

Test::Class::Filter::Tags

The original impetus for this module. Permits specifying tags on test methods, and then running only a subset of tests, matching a given tag list.
