70 | |
e295d072 |
71 | While L<Moose> attributes provide you with a way to name your accessors, |
72 | readers, writers, clearers and predicates, this library provides commonly |
73 | used attribute helper methods for more specific types of data. |
74 | |
75 | As seen in the L</SYNOPSIS>, you specify the extension via the |
76 | C<metaclass> parameter. Available meta classes are: |
77 | |
c43a2317 |
78 | =head1 PARAMETERS |
79 | |
80 | =head2 provides |
81 | |
82 | This points to a hashref that uses C<provider> for the keys and |
3656a0d7 |
83 | C<method> for the values. The method will be added to |
c43a2317 |
84 | the object itself and do what you want. |
85 | |
86 | =head2 curries |
87 | |
88 | This points to a hashref that uses C<provider> for the keys and |
696d4dc7 |
89 | has two choices for the value: |
90 | |
91 | You can supply C<< {method => [ @args ]} >> for the values. The method will be |
92 | added to the object itself (always using C<@args> as the beginning arguments). |
93 | |
94 | Another approach to curry a method provider is to supply a coderef instead of an |
95 | arrayref. The code ref takes C<$self>, C<$body>, and any additional arguments |
96 | passed to the final method. |
97 | |
98 | # ... |
99 | |
100 | curries => { |
101 | grep => { |
102 | times_with_day => sub { |
103 | my ($self, $body, $datetime) = @_; |
104 | $body->($self, sub { $_->ymd eq $datetime->ymd }); |
105 | } |
106 | } |
107 | } |
108 | |
109 | # ... |
110 | |
111 | $obj->times_with_day(DateTime->now); # takes datetime argument, checks day |

144 | =head1 CAVEAT |
145 | |
146 | This is an early release of this module. Right now it is in great need |
147 | of documentation and tests in the test suite. However, we have used this |
c91a1347 |
148 | module to great success at C<$work> where it has been tested very thoroughly |
5431dff2 |
149 | and deployed into a major production site. |
150 | |
151 | I plan on getting better docs and tests in the next few releases, but until |
152 | then please refer to the few tests we do have and feel free email and/or |
153 | message me on irc.perl.org if you have any questions. |
154 | |
155 | =head1 TODO |
156 | |
157 | We need tests and docs badly. |

159 | =head1 BUGS |
160 | |
161 | All complex software has bugs lurking in it, and this module is no |
162 | exception. If you find a bug please either email me, or add the bug |
163 | to cpan-RT. |
