1.1 andrew 378:
379: =head1 SYNOPSIS
380:
381: use Text::Todo;
1.10 andrew 382:
383: my $todo = Text::Todo->new('todo/todo.txt');
384:
385: foreach my $e (sort { lc($_->text) cmp lc($e->text)} $todo->list) {
386: print $e->text, "\n";
387: }
388:
1.1 andrew 389:
390: =head1 DESCRIPTION
391:
1.10 andrew 392: This module is a basic interface to the todo.txt files as described by
393: Lifehacker and extended by members of their community.
394:
1.4 andrew 395: For more information see L<http://todotxt.com>
1.1 andrew 396:
1.10 andrew 397: This module supports the 3 axes of an effective todo list.
398: Priority, Project and Context.
399:
400: It does not support other notations or many of the more advanced features of
401: the todo.sh like plugins.
402:
403: It should be extensible, but and hopefully will be before a 1.0 release.
404:
405:
1.1 andrew 406: =head1 INTERFACE
407:
1.2 andrew 408: =head2 new
409:
1.10 andrew 410: new({
411: [ todo_dir => 'directory', ]
412: [ todo_file => 'filename in todo_dir', ]
413: [ done_file => 'filename in todo_dir', ]
414: [ report_file => 'filename in todo_dir', ]
415: });
416:
417: Allows you to set each item individually. todo_file defaults to todo.txt.
418:
419: new('path/to/todo.txt');
420:
421: Automatically sets todo_dir to 'path/to', todo_file to 'todo.txt'
422:
423: new('path/to')
424:
425: If you pass an existing directory to new, it will set todo_dir.
426:
427:
428: If you what you set matches (.*)todo(.*).txt it will automatically set
429: done_file to $1done$2.txt
430: and
431: report_file to $1report$2.txt.
432:
433: For example, new('todo/todo.shopping.txt') will set
434: todo_dir to 'todo',
435: todo_file to 'todo.shopping.txt',
436: done_file to 'done.shopping.txt',
437: and
438: report_file to 'report.shopping.txt'.
439:
1.9 andrew 440: =head2 file
441:
1.10 andrew 442: Allows you to read the paths to the files in use.
443: If as in the SYNOPSIS above you used $todo = new('todo/todo.txt').
444:
445: $todo_file = $todo->file('todo_file');
446:
447: then, $todo_file eq 'todo/todo.txt'
448:
1.2 andrew 449: =head2 load
450:
1.10 andrew 451: Allows you to load a different file into the object.
452:
453: $todo->load('done_file');
454:
455: This effects the other functions that act on the list.
456:
1.2 andrew 457: =head2 save
458:
1.10 andrew 459: $todo->save(['new/path/to/todo']);
460:
461: Writes the list to the file. Either the current working file or something
462: that can be recognized by file().
463:
464: If you specify a filename it will save to that file and update the paths.
465: Additional changes to the object work on that file.
466:
1.9 andrew 467: =head2 list
468:
1.10 andrew 469: my @todo_list = $todo->list;
470:
1.9 andrew 471: =head2 listpri
1.3 andrew 472:
1.10 andrew 473: Like list, but only returns entries that have priority set.
474:
475: my @priority_list = $todo->listpri;
476:
1.9 andrew 477: =head2 listproj
1.3 andrew 478:
1.10 andrew 479: Returns projects in the list sorted by name.
480: If there were projects +GarageSale and +Shopping
481:
482: my @projects = $todo->listproj;
483:
484: is the same as
485:
486: @projects = ( 'GarageSale', 'Shopping' );
487:
1.3 andrew 488: =head2 add
1.9 andrew 489:
1.10 andrew 490: Adds a new entry to the list.
491: Can either be a Text::Todo::Entry object or plain text.
492:
493: $todo->add('new todo entry');
494:
495: It then becomes $todo->list->[-1];
496:
1.9 andrew 497: =head2 del
498:
1.10 andrew 499: Remove an entry from the list, either the reference or by number.
500:
501: $removed_entry = $todo->del($entry);
502:
503: $entry can either be an Text::Todo::Entry in the list or the index of the
504: entry to delete.
505:
506: Note that entries are 0 indexed (as expected in perl) not starting at line 1.
507:
1.9 andrew 508: =head2 move
509:
1.10 andrew 510: $todo->move($entry, $new_pos);
511:
512: $entry can either be the number of the entry or the actual entry.
513: $new_pos is the new position to put it.
514:
515: Note that entries are 0 indexed (as expected in perl) not starting at line 1.
516:
1.9 andrew 517: =head2 archive
518:
1.10 andrew 519: $todo->archive
520:
521: Iterates over the list and for each done entry,
522: addto('done_file')
523: and
524: del($entry).
525: If any were archived it will then
526: save()
527: and
528: load().
529:
1.9 andrew 530: =head2 addto
531:
1.10 andrew 532: $todo->addto($file, $entry);
1.1 andrew 533:
1.10 andrew 534: Appends text to the file.
535: $file can be anyting recognized by file().
536: $entry can either be a Text::Todo::Entry or plain text.
1.1 andrew 537:
1.10 andrew 538: =head2 listfile
1.1 andrew 539:
1.10 andrew 540: @list = $todo->listfile($file);
1.1 andrew 541:
1.10 andrew 542: Read a file and returns a list like $todo->list but does not update the
543: internal list that is being worked with.
544: $file can be anyting recognized by file().
1.1 andrew 545:
546:
1.10 andrew 547: =head1 DIAGNOSTICS
1.1 andrew 548:
1.10 andrew 549: Most methods return undef on failure.
1.1 andrew 550:
1.10 andrew 551: Some more important methods are fatal.
1.1 andrew 552:
553:
554: =head1 CONFIGURATION AND ENVIRONMENT
555:
556: Text::Todo requires no configuration files or environment variables.
557:
1.10 andrew 558: Someday it should be able to read and use the todo.sh config file. This may
559: possibly be better done in a client that would use this module.
