25 ;; This package provides facilities for making, displaying, navigating
26 ;; and editing todo lists, which are prioritized lists of todo items.
27 ;; Todo lists are identified with named categories, so you can group
28 ;; together and separately prioritize thematically related todo items.
29 ;; Each category is stored in a file, which thus provides a further
30 ;; level of organization. You can create as many todo files, and in
31 ;; each as many categories, as you want.
33 ;; With Todos you can navigate among the items of a category, and
34 ;; between categories in the same and in different todo files. You
35 ;; can edit todo items, reprioritize them within their category, move
36 ;; them to another category, delete them, or mark items as done and
37 ;; store them separately from the not yet done items in a category.
38 ;; You can add new todo files and categories, rename categories, move
39 ;; them to another file or delete them. You can also display summary
40 ;; tables of the categories in a file and the types of items they
41 ;; contain. And you can build cross-categorial lists of items that
42 ;; satisfy various criteria.
44 ;; To get started, load this package and type `M-x todos-show'. This
45 ;; will prompt you for the name of the first todo file, its first
46 ;; category and the category's first item, create these and display
47 ;; them in Todos mode. Now you can insert further items into the list
48 ;; (i.e., the category) and assign them priorities by typing `i i'.
50 ;; You will probably find it convenient to give `todos-show' a global
51 ;; key binding in your init file, since it is one of the entry points
52 ;; to Todos mode; a good choice is `C-c t', since `todos-show' is
53 ;; bound to `t' in Todos mode.
55 ;; To see a list of all Todos mode commands and their key bindings,
56 ;; including other entry points, type `C-h m' in Todos mode. Consult
57 ;; the document strings of the commands for details of their use. The
58 ;; `todos' customization group and its subgroups list the options you
59 ;; can set to alter the behavior of many commands and various aspects
62 ;; This package is a new version of Oliver Seidel's todo-mode.el.
63 ;; While it retains the same basic organization and handling of todo
64 ;; lists and the basic UI, it significantly extends these, adds many
65 ;; features, changes much of the internals and reimplements almost all

1604 "Insert a new Todo item into a category.
1605 This is the function from which the generated Todos item
1606 insertion commands derive.
1608 The generated commands have mnenomic key bindings based on the
1609 arguments' values and their order in the command's argument list,
1610 as follows: (1) for DIARY `d', (2) for NONMARKING `k', (3) for
1611 DATE-TYPE either `c' for calendar or `d' for date or `n' for
1612 weekday name, (4) for TIME `t', (5) for REGION-OR-HERE either `r'
1613 for region or `h' for here. Sequences of these keys are appended
1614 to the insertion prefix key `i'. Keys that allow a following
1615 key (i.e., any but `r' or `h') must be doubled when used finally.
1616 For example, the command bound to the key sequence `i y h' will
1617 insert a new item with today's date, marked according to the
1618 DIARY argument described below, and with priority according to
1619 the HERE argument; `i y y' does the same except that the priority
1620 is not given by HERE but by prompting.
1622 In command invocations, ARG is passed as a prefix argument as
1623 follows. With no prefix argument, add the item to the current
1624 category; with one prefix argument (`C-u'), prompt for a category
1625 from the current Todos file; with two prefix arguments (`C-u C-u'),
1626 first prompt for a Todos file, then a category in that file. If
1627 a non-existing category is entered, ask whether to add it to the
1628 Todos file; if answered affirmatively, add the category and
1629 insert the item there.
1631 The remaining arguments are set or left nil by the generated item
1632 insertion commands; their meanings are described in the follows
1635 When argument DIARY is non-nil, this overrides the intent of the
1636 user option `todos-include-in-diary' for this item: if
1637 `todos-include-in-diary' is nil, include the item in the Fancy
1638 Diary display, and if it is non-nil, exclude the item from the
1639 Fancy Diary display. When DIARY is nil, `todos-include-in-diary'
1640 has its intended effect.
1642 When the item is included in the Fancy Diary display and the
1643 argument NONMARKING is non-nil, this overrides the intent of the
1644 user option `todos-diary-nonmarking' for this item: if
1645 `todos-diary-nonmarking' is nil, append `diary-nonmarking-symbol'
1646 to the item, and if it is non-nil, omit `diary-nonmarking-symbol'.
1648 The argument DATE-TYPE determines the content of the item's
1649 mandatory date header string and how it is added:
1650 - If DATE-TYPE is the symbol `calendar', the Calendar pops up and
1651 when the user puts the cursor on a date and hits RET, that
1652 date, in the format set by `calendar-date-display-form',
1653 becomes the date in the header.
1654 - If DATE-TYPE is a string matching the regexp
1655 `todos-date-pattern', that string becomes the date in the
1656 header. This case is for the command
1657 `todos-insert-item-from-calendar' which is called from the
1659 - If DATE-TYPE is the symbol `date', the header contains the date
1660 in the format set by `calendar-date-display-form', with year,
1661 month and day individually prompted for (month with tab
1663 - If DATE-TYPE is the symbol `dayname' the header contains a
1664 weekday name instead of a date, prompted for with tab
1666 - If DATE-TYPE has any other value (including nil or none) the
1667 header contains the current date (in the format set by
1668 `calendar-date-display-form').
1670 With non-nil argument TIME prompt for a time string, which must
1671 match `diary-time-regexp'. Typing `<return>' at the prompt
1672 returns the current time, if the user option
1673 `todos-always-add-time-string' is non-nil, otherwise the empty
1674 string (i.e., no time string). If TIME is absent or nil, add or
1675 omit the current time string according as
1676 `todos-always-add-time-string' is non-nil or nil, respectively.
1678 The argument REGION-OR-HERE determines the source and location of
1680 - If the REGION-OR-HERE is the symbol `here', prompt for the text of
1681 the new item and, if the command was invoked with point in the todo
1682 items section of the current category, give the new item the
1683 priority of the item at point, lowering the latter's priority and
1684 the priority of the remaining items. If point is in the done items
1685 section of the category, insert the new item as the first todo item
1686 in the category. Likewise, if the command with `here' is invoked
1687 outside of the current category, jump to the chosen category and
1688 insert the new item as the first item in the category.
1689 - If REGION-OR-HERE is the symbol `region', use the region of the
1690 current buffer as the text of the new item, depending on the
1691 value of user option `todos-use-only-highlighted-region': if
1692 this is non-nil, then use the region only when it is
1693 highlighted; otherwise, use the region regardless of
1694 highlighting. An error is signalled if there is no region in
1695 the current buffer. Prompt for the item's priority in the
1696 category (an integer between 1 and one more than the number of
1697 items in the category), and insert the item accordingly.
1698 - If REGION-OR-HERE has any other value (in particular, nil or
1699 none), prompt for the text and the item's priority, and insert
1700 the item accordingly."
