1.1 andrew 262: =head1 DESCRIPTION
263:
1.12 andrew 264: This module creates entries in a Text::Todo list.
265: It allows you to retrieve information about them and modify them.
266:
267: For more information see L<http://todotxt.com>
1.1 andrew 268:
269:
270: =head1 INTERFACE
271:
1.22 andrew 272: =head2 new
1.12 andrew 273:
274: Creates an entry that can be manipulated.
1.1 andrew 275:
1.13 andrew 276: my $entry = Text::Todo::Entry->new([
277: 'text of entry' | {
278: [ text => 'text of entry' ,]
279: [ tags => { additional_arg => 'identfier' }, ]
280: } ]);
1.12 andrew 281:
282: If you don't pass any text, creates a blank entry.
1.1 andrew 283:
1.13 andrew 284: See tags below for a description of additional tags.
285:
1.1 andrew 286: =head2 text
287:
1.12 andrew 288: Returns the text of the entry.
289:
290: print $entry->text, "\n";
291:
292: =head2 pri
293:
294: Sets the priority of an entry. If the priority is set to an empty string,
295: clears the priority.
296:
297: $entry->pri('B');
298:
299: Acceptible entries are an empty string, A-Z or a-z. Anything else will cause
300: an error.
301:
302: =head2 depri
303:
304: A convenience function that unsets priority by calling pri('').
305:
306: $entry->depri;
307:
1.1 andrew 308: =head2 priority
309:
1.12 andrew 310: Returns the priority of an entry which may be an empty string if it is
1.1 andrew 311:
1.12 andrew 312: my $priority = $entry->priority;
1.1 andrew 313:
1.12 andrew 314: =head2 tags
1.1 andrew 315:
1.12 andrew 316: Each tag type generates two accessor functions {tag}s and in_{tag}.
1.1 andrew 317:
1.12 andrew 318: Current tags are context (@) and project (+).
1.13 andrew 319:
320: When creating a new object you can pass in new tags to recognize.
321:
322: my $entry = Text::Todo::Entry->new({
323: text => 'do something DUE:2011-01-01',
324: tags => { due_date => 'DUE:' }
325: });
326:
327: my @due_dates = $entry->due_dates;
328:
329: then @due_dates eq ( '2011-01-01' );
330:
331: and you could also:
332:
333: if ($entry->in_due_date('2011-01-01')) {
334: # do something
335: }

1.7 andrew 343:
1.12 andrew 344: =item in_{tag}
1.7 andrew 345:
1.12 andrew 346: returns true if $entry is in the tag, false if not.

384:
385: =head2 prepend
386:
387: Attaches text (with a trailing space) to the beginning of an entry. Puts it

391:
392: =head2 append
393:
394: Adds text to the end of an entry.

1.12 andrew 412: # remind me to do it
413: }
414:
1.18 andrew 415: If the entry starts as 'x date', for example 'x 2010-01-01', $status is now
416: '2010-01-01'.
417: If the entry just starts with 'x', then $status will be 'x'.
