|
176 |
=head1 DESCRIPTION |
177 |
|
178 |
The C<mkcommitfeed.pl> script provides a command-line interface to |
179 |
update an Atom Feed that is intended for providing commit logs for a |
180 |
software developmenet project. |
181 |
|
182 |
The script, when invoked, adds an Atom Entry that describes a change |
183 |
made to the project's repository. |
184 |
|
185 |
=head1 STANDARD INPUT |
186 |
|
187 |
A description for the change must be specified to the standard input. |
188 |
It is used as the plain text content of the atom:content element of |
189 |
the Entry for the change to add. |
190 |
|
191 |
Non-ASCII characters are not supported in this version of this script. |
192 |
Maybe a future version of this script would support UTF-8. |
193 |
|
194 |
=head1 ARGUMENTS |
195 |
|
196 |
There are command-line options for the script. Some of them are |
197 |
required, while the others are optional. As a general rule, an option |
198 |
whose name begins with C<--entry> specifies a property for the Entry |
199 |
to add, while an option whose name begins with C<--feed> specifies a |
200 |
property for the entire Feed. Option values for Feed properties might |
201 |
not be used when updating an existing Feed document. |
202 |
|
203 |
=over 4 |
204 |
|
205 |
=item C<--entry-author-mail I<foo@domain.example>> (optional) |
206 |
|
207 |
Specifies the mail address of the person who made a change. It is |
208 |
used as the content of the C<atom:email> element of the C<atom:author> |
209 |
element of the Entry. |
210 |
|
211 |
If this option is not specified, but the standard input includes a |
212 |
ChangeLog entry in the standard GNU format, then the mail address is |
213 |
taken from the ChangeLog entry. Otherwise, C<atom:email> element is |
214 |
not specified. |
215 |
|
216 |
The option value must be an RFC 2822 C<addr-spec> that does not match |
217 |
C<obs-addr-spec> (i.e. standard email address format). Otherwise the |
218 |
generated Feed would be non-conforming. |
219 |
|
220 |
=item C<--entry-author-name I<author-name>> (conditionally required) |
221 |
|
222 |
Specifies the human readable name of the person who made a change. It |
223 |
is used as the content of the C<atom:name> element of the |
224 |
C<atom:author> element of the Entry. |
225 |
|
226 |
If this option is not specified, but the standard input includes a |
227 |
ChangeLog entry in the standard GNU format, then the name is taken |
228 |
from the ChangeLog entry. If the standard input does not include a |
229 |
GNU format ChangeLog entry, then the C<--entry-author-name> option |
230 |
must be specified. |
231 |
|
232 |
Non-ASCII characters are not supported in this version of this script. |
233 |
|
234 |
=item C<--entry-content I<description>> (optional) |
235 |
|
236 |
Specifies the description of the change. It is used as the content of |
237 |
the C<atom:content> element of the Entry, with C<type=text>. |
238 |
|
239 |
If this option is specified, its value is used as if it were from the |
240 |
standard input and the actual standard input, if any, is ignored. If |
241 |
neither this option nor the standard input is specified, then the |
242 |
description is assumed as the empty string. |
243 |
|
244 |
Non-ASCII characters are not supported in this version of this script. |
245 |
|
246 |
=item C<--entry-title I<title>> (optional) |
247 |
|
248 |
Specifies the title of the change. It is used as the content of the |
249 |
C<atom:title> element of the Entry, with C<type=text>. |
250 |
|
251 |
If this option is not specified, then the date of the change, as well |
252 |
as the name of the author, is used as title. |
253 |
|
254 |
Non-ASCII characters are not supported in this version of this script. |
255 |
|
256 |
=item C<--feed-author-mail I<foo@domain.example>> (optional) |
257 |
|
258 |
Specifies the mail address of the author of the Feed. It is used as |
259 |
the content of the C<atom:email> element of the C<atom:author> element |
260 |
of the Feed. |
261 |
|
262 |
This option is ignored if the C<--feed-author-name> option is not |
263 |
specified. |
264 |
|
265 |
If this option is not specified, C<atom:email> element is not |
266 |
specified. |
267 |
|
268 |
The option value must be an RFC 2822 C<addr-spec> that does not match |
269 |
C<obs-addr-spec> (i.e. standard email address format). Otherwise the |
270 |

271 |
|
272 |
This option is ignored if the Feed already has an C<atom:author> |
273 |
element. |
274 |
|
275 |
=item C<--feed-author-name I<author-name>> (optional) |
276 |
|
277 |
Specifies the human readable name of the author of the Feed. It is |

282 |

296 |
ignored. |
297 |
|

299 |
specified. |
300 |
|
301 |
The option value must be a URI reference conforming to RFC 3986. It |
302 |

|
321 |
=item C<--feed-license-url I<url>> (optional) |
322 |
|
323 |
Specifies the URL that describes the license of the Feed. It is used |
324 |
as the C<href> attribute value of an C<atom:link> element whose C<rel> |
325 |

326 |
|
327 |

328 |
is C<license> is not specified. |
329 |
|
330 |

342 |

344 |
|
345 |
If this option is not specified, the C<atom:link> element whose C<rel> |
346 |
is C<related> is not specified. |
347 |
|
348 |
