1.1 andrew 401:
402: =head1 SYNOPSIS
403:
404: use Text::Todo;
1.10 andrew 405:
406: my $todo = Text::Todo->new('todo/todo.txt');
407:
408: foreach my $e (sort { lc($_->text) cmp lc($e->text)} $todo->list) {
409: print $e->text, "\n";
410: }
411:
1.1 andrew 412:
413: =head1 DESCRIPTION
414:
1.10 andrew 415: This module is a basic interface to the todo.txt files as described by
416: Lifehacker and extended by members of their community.
417:
1.4 andrew 418: For more information see L<http://todotxt.com>
1.1 andrew 419:
1.10 andrew 420: This module supports the 3 axes of an effective todo list.
421: Priority, Project and Context.
422:
423: It does not support other notations or many of the more advanced features of
424: the todo.sh like plugins.
425:
426: It should be extensible, but and hopefully will be before a 1.0 release.
427:
428:
1.1 andrew 429: =head1 INTERFACE
430:
1.2 andrew 431: =head2 new
432:
1.10 andrew 433: new({
434: [ todo_dir => 'directory', ]
435: [ todo_file => 'filename in todo_dir', ]
436: [ done_file => 'filename in todo_dir', ]
437: [ report_file => 'filename in todo_dir', ]
438: });
439:
440: Allows you to set each item individually. todo_file defaults to todo.txt.
441:
442: new('path/to/todo.txt');
443:
444: Automatically sets todo_dir to 'path/to', todo_file to 'todo.txt'
445:
446: new('path/to')
447:
448: If you pass an existing directory to new, it will set todo_dir.
449:
450:
451: If you what you set matches (.*)todo(.*).txt it will automatically set
452: done_file to $1done$2.txt
453: and
454: report_file to $1report$2.txt.
455:
456: For example, new('todo/todo.shopping.txt') will set
457: todo_dir to 'todo',
458: todo_file to 'todo.shopping.txt',
459: done_file to 'done.shopping.txt',
460: and
461: report_file to 'report.shopping.txt'.
462:
1.9 andrew 463: =head2 file
464:
1.10 andrew 465: Allows you to read the paths to the files in use.
466: If as in the SYNOPSIS above you used $todo = new('todo/todo.txt').
467:
468: $todo_file = $todo->file('todo_file');
469:
470: then, $todo_file eq 'todo/todo.txt'
471:
1.2 andrew 472: =head2 load
473:
1.10 andrew 474: Allows you to load a different file into the object.
475:
476: $todo->load('done_file');
477:
478: This effects the other functions that act on the list.
479:
1.2 andrew 480: =head2 save
481:
1.10 andrew 482: $todo->save(['new/path/to/todo']);
483:
484: Writes the list to the file. Either the current working file or something
485: that can be recognized by file().
486:
487: If you specify a filename it will save to that file and update the paths.
488: Additional changes to the object work on that file.
489:
1.9 andrew 490: =head2 list
491:
1.10 andrew 492: my @todo_list = $todo->list;
493:
1.9 andrew 494: =head2 listpri
1.3 andrew 495:
1.10 andrew 496: Like list, but only returns entries that have priority set.
497:
498: my @priority_list = $todo->listpri;
499:
1.9 andrew 500: =head2 listproj
1.3 andrew 501:
1.10 andrew 502: Returns projects in the list sorted by name.
503: If there were projects +GarageSale and +Shopping
504:
505: my @projects = $todo->listproj;
506:
507: is the same as
508:
509: @projects = ( 'GarageSale', 'Shopping' );
510:
1.3 andrew 511: =head2 add
1.9 andrew 512:
1.10 andrew 513: Adds a new entry to the list.
514: Can either be a Text::Todo::Entry object or plain text.
515:
516: $todo->add('new todo entry');
517:
518: It then becomes $todo->list->[-1];
519:
1.9 andrew 520: =head2 del
521:
1.10 andrew 522: Remove an entry from the list, either the reference or by number.
523:
524: $removed_entry = $todo->del($entry);
525:
526: $entry can either be an Text::Todo::Entry in the list or the index of the
527: entry to delete.
528:
529: Note that entries are 0 indexed (as expected in perl) not starting at line 1.
530:
1.9 andrew 531: =head2 move
532:
1.10 andrew 533: $todo->move($entry, $new_pos);
534:
535: $entry can either be the number of the entry or the actual entry.
536: $new_pos is the new position to put it.
537:
538: Note that entries are 0 indexed (as expected in perl) not starting at line 1.
539:
1.9 andrew 540: =head2 archive
541:
1.10 andrew 542: $todo->archive
543:
544: Iterates over the list and for each done entry,
545: addto('done_file')
546: and
547: del($entry).
548: If any were archived it will then
549: save()
550: and
551: load().
552:
1.9 andrew 553: =head2 addto
554:
1.10 andrew 555: $todo->addto($file, $entry);
1.1 andrew 556:
1.10 andrew 557: Appends text to the file.
558: $file can be anyting recognized by file().
559: $entry can either be a Text::Todo::Entry or plain text.
1.1 andrew 560:
1.10 andrew 561: =head2 listfile
1.1 andrew 562:
1.10 andrew 563: @list = $todo->listfile($file);
1.1 andrew 564:
1.10 andrew 565: Read a file and returns a list like $todo->list but does not update the
566: internal list that is being worked with.
567: $file can be anyting recognized by file().
1.1 andrew 568:
569:
1.10 andrew 570: =head1 DIAGNOSTICS
1.1 andrew 571:
1.10 andrew 572: Most methods return undef on failure.
1.1 andrew 573:
1.10 andrew 574: Some more important methods are fatal.
