27 ;; This package provides facilities for making, displaying, navigating
28 ;; and editing todo lists, which are prioritized lists of todo items.
29 ;; Todo lists are identified with named categories, so you can group
30 ;; together and separately prioritize thematically related todo items.
31 ;; Each category is stored in a file, which thus provides a further
32 ;; level of organization. You can create as many todo files, and in
33 ;; each as many categories, as you want.
35 ;; With Todo mode you can navigate among the items of a category, and
36 ;; between categories in the same and in different todo files. You
37 ;; can edit todo items, reprioritize them within their category, move
38 ;; them to another category, delete them, or mark items as done and
39 ;; store them separately from the not yet done items in a category.
40 ;; You can add new todo files, edit and delete them. You can add new
41 ;; categories, rename and delete them, move categories to another file
42 ;; and merge the items of two categories. You can also reorder the
43 ;; sequence of categories in a todo file for the purpose of
44 ;; navigation. You can display summary tables of the categories in a
45 ;; file and the types of items they contain. And you can compile
46 ;; lists of existing items from multiple categories in one or more
47 ;; todo files, which are filtered by various criteria.
49 ;; To get started, load this package and type `M-x todo-show'. This
50 ;; will prompt you for the name of the first todo file, its first
51 ;; category and the category's first item, create these and display
52 ;; them in Todo mode. Now you can insert further items into the list
53 ;; (i.e., the category) and assign them priorities by typing `i i'.
55 ;; You will probably find it convenient to give `todo-show' a global
56 ;; key binding in your init file, since it is one of the entry points
57 ;; to Todo mode; a good choice is `C-c t', since `todo-show' is
58 ;; bound to `t' in Todo mode.
60 ;; To see a list of all Todo mode commands and their key bindings,
61 ;; including other entry points, type `C-h m' in Todo mode. Consult
62 ;; the documentation strings of the commands for details of their use.
63 ;; The `todo' customization group and its subgroups list the options
64 ;; you can set to alter the behavior of many commands and various
65 ;; aspects of the display.
67 ;; This package is a new version of Oliver Seidel's todo-mode.el.
68 ;; While it retains the same basic organization and handling of todo
69 ;; lists and the basic UI, it significantly extends these and adds
70 ;; many features. This required also making changes to the internals,
71 ;; including the file format. If you have a todo file in old format,
72 ;; then the first time you invoke `todo-show' (i.e., before you have
73 ;; created any todo file in the current format), it will ask you
74 ;; whether to convert that file and show it. If you choose not to
75 ;; convert the old-style file at this time, you can do so later by
76 ;; calling the command `todo-convert-legacy-files'.

1734 "Insert a new todo item into a category.
1735 This is the function from which the generated Todo mode item
1736 insertion commands derive.
1738 The generated commands have mnemonic key bindings based on the
1739 arguments' values and their order in the command's argument list,
1740 as follows: (1) for DIARY `d', (2) for NONMARKING `k', (3) for
1741 DATE-TYPE either `c' for calendar or `d' for date or `n' for
1742 weekday name, (4) for TIME `t', (5) for REGION-OR-HERE either `r'
1743 for region or `h' for here. Sequences of these keys are appended
1744 to the insertion prefix key `i'. Keys that allow a following
1745 key (i.e., any but `r' or `h') must be doubled when used finally.
1746 For example, the command bound to the key sequence `i y h' will
1747 insert a new item with today's date, marked according to the
1748 DIARY argument described below, and with priority according to
1749 the HERE argument; `i y y' does the same except that the priority
1750 is not given by HERE but by prompting.
1752 In command invocations, ARG is passed as a prefix argument as
1753 follows. With no prefix argument, add the item to the current
1754 category; with one prefix argument (`C-u'), prompt for a category
1755 from the current todo file; with two prefix arguments (`C-u C-u'),
1756 first prompt for a todo file, then a category in that file. If
1757 a non-existing category is entered, ask whether to add it to the
1758 todo file; if answered affirmatively, add the category and
1759 insert the item there.
1761 The remaining arguments are set or left nil by the generated item
1762 insertion commands; their meanings are described in the follows
1765 When argument DIARY is non-nil, this overrides the intent of the
1766 user option `todo-include-in-diary' for this item: if
1767 `todo-include-in-diary' is nil, include the item in the Fancy
1768 Diary display, and if it is non-nil, exclude the item from the
1769 Fancy Diary display. When DIARY is nil, `todo-include-in-diary'
1770 has its intended effect.
1772 When the item is included in the Fancy Diary display and the
1773 argument NONMARKING is non-nil, this overrides the intent of the
1774 user option `todo-diary-nonmarking' for this item: if
1775 `todo-diary-nonmarking' is nil, append `diary-nonmarking-symbol'
1776 to the item, and if it is non-nil, omit `diary-nonmarking-symbol'.
1778 The argument DATE-TYPE determines the content of the item's
1779 mandatory date header string and how it is added:
1780 - If DATE-TYPE is the symbol `calendar', the Calendar pops up and
1781 when the user puts the cursor on a date and hits RET, that
1782 date, in the format set by `calendar-date-display-form',
1783 becomes the date in the header.
1784 - If DATE-TYPE is a string matching the regexp
1785 `todo-date-pattern', that string becomes the date in the
1786 header. This case is for the command
1787 `todo-insert-item-from-calendar' which is called from the
1789 - If DATE-TYPE is the symbol `date', the header contains the date
1790 in the format set by `calendar-date-display-form', with year,
1791 month and day individually prompted for (month with tab
1793 - If DATE-TYPE is the symbol `dayname' the header contains a
1794 weekday name instead of a date, prompted for with tab
1796 - If DATE-TYPE has any other value (including nil or none) the
1797 header contains the current date (in the format set by
1798 `calendar-date-display-form').
1800 With non-nil argument TIME prompt for a time string, which must
1801 match `diary-time-regexp'. Typing `<return>' at the prompt
1802 returns the current time, if the user option
1803 `todo-always-add-time-string' is non-nil, otherwise the empty
1804 string (i.e., no time string). If TIME is absent or nil, add or
1805 omit the current time string according as
1806 `todo-always-add-time-string' is non-nil or nil, respectively.
1808 The argument REGION-OR-HERE determines the source and location of
1810 - If the REGION-OR-HERE is the symbol `here', prompt for the text of
1811 the new item and, if the command was invoked with point in the todo
1812 items section of the current category, give the new item the
1813 priority of the item at point, lowering the latter's priority and
1814 the priority of the remaining items. If point is in the done items
1815 section of the category, insert the new item as the first todo item
1816 in the category. Likewise, if the command with `here' is invoked
1817 outside of the current category, jump to the chosen category and
1818 insert the new item as the first item in the category.
1819 - If REGION-OR-HERE is the symbol `region', use the region of the
1820 current buffer as the text of the new item, depending on the
1821 value of user option `todo-use-only-highlighted-region': if
1822 this is non-nil, then use the region only when it is
1823 highlighted; otherwise, use the region regardless of
1824 highlighting. An error is signalled if there is no region in
1825 the current buffer. Prompt for the item's priority in the
1826 category (an integer between 1 and one more than the number of
1827 items in the category), and insert the item accordingly.
1828 - If REGION-OR-HERE has any other value (in particular, nil or
1829 none), prompt for the text and the item's priority, and insert
1830 the item accordingly."
