=head1 DESCRIPTION |
138
|
|
|
|
|
|
|
|
139
|
|
|
|
|
|
|
This module provides various useful Moose types and associated |
140
|
|
|
|
|
|
|
coercions that are needed in the LCFG Package Forge suite. |

=item AbsolutePath |
147
|
|
|
|
|
|
|
|
148
|
|
|
|
|
|
|
A type based on the Moose string type (Str) which requires it to be an |
149
|
|
|
|
|
|
|
absolute path. There is an associated coercion which can be used to |
150
|
|
|
|
|
|
|
promote a relative path to an absolute path. |
151

=item AbsolutePathDirectory |
153
|
|
|
|
|
|
|
|
154
|
|
|
|
|
|
|
A type based on the AbsolutePath type which also requires it to be a |
155
|
|
|
|
|
|
|
directory. Again there is an associated coercion to promote a relative |
156
|
|
|
|
|
|
|
path to absolute. |
157

=item EmailAddress |
159
|
|
|
|
|
|
|
|
160
|
|
|
|
|
|
|
A type based on the Moose string type (Str) which requires it to be a |
161
|
|
|
|
|
|
|
valid email address. The L<Email::Valid> module is required to do the |
162
|
|
|
|
|
|
|
validation. |
163
|
|
|
|
|
|
|
|
164
|
|
|
|
|
|
|
=item EmailAddressList |
165
|
|
|
|
|
|
|
|
166
|
|
|
|
|
|
|
This list type is based on the Moose ArrayRef type with the |
167
|
|
|
|
|
|
|
requirement that all elements are of the C<EmailAddress> type. |
168
|
|
|
|
|

=item UserName |
170
|
|
|
|
|
|
|
|
171
|
|
|
|
|
|
|
This is a string type which represents a user name. Anything which is |
172
|
|
|
|
|
|
|
NOT just a sequence of digits (i.e. looks like a UID) will be |
173
|
|
|
|
|
|
|
allowed. If a UID is passed in it will be passed through the |
174
|
|
|
|
|
|
|
C<getpwuid> function to retrieve the associated username. |
175
|
|
|
|
|
|
|
|
176
|
|
|
|
|
|
|
=item UID |
177
|
|
|
|
|
|
|
|
178
|
|
|
|
|
|
|
This is an integer type which represents a user ID (UID). Anything |
179
|
|
|
|
|
|
|
which is not an integer will be passed through the C<getpwnam> |
180
|
|
|
|
|
|
|
function to retrieve the associated UID. |
181
|
|
|
|
|
|
|
|
182
|
|
|
|
|
|
|
=item Octal |
183
|
|
|
|
|
|
|
|
184
|
|
|
|
|
|
|
This is a string type which represents an octal number. It expects the |
185
|
|
|
|
|
|
|
string to start with a zero followed by a sequence of digits. This is |
186
|
|
|
|
|
|
|
aimed at attributes which represent Unix file permission modes. |
187
|
|
|
|
|
|
|
|
188
|
|
|
|
|
|
|
=item NoCommas |
189
|
|
|
|
|
|
|
|
190
|
|
|
|
|
|
|
This type is based on the Moose string type (Str) which requires that |
191
|
|
|
|
|
|
|
the string does not contain any commas. |
192
|
|
|
|
|
|
|
|
193
|
|
|
|
|
|
|
=item PkgForgeList |
194
|
|
|
|
|
|
|
|
195
|
|
|
|
|
|
|
This type is based on the Moose ArrayRef type with the requirement |
196
|
|
|
|
|
|
|
that each element is of the C<NoCommas> type. The interesting aspect |
197
|
|
|
|
|
|
|
of this type is the associated coercions from Str and ArrayRef |
198
|
|
|
|
|
|
|
types. When coercing from a string it will be split on commas and the |
199
|
|
|
|
|
|
|
resulting list will be used. When coercing from a list each element |
200
|
|
|
|
|
|
|
will be passed through the same string coercion to split on commas. |
