+;;; Commentary:
+
+;; This package provides facilities for making, displaying, navigating
+;; and editing todo lists, which are prioritized lists of todo items.
+;; Todo lists are identified with named categories, so you can group
+;; together and separately prioritize thematically related todo items.
+;; Each category is stored in a file, which thus provides a further
+;; level of organization. You can create as many todo files, and in
+;; each as many categories, as you want.
+
+;; With Todo mode you can navigate among the items of a category, and
+;; between categories in the same and in different todo files. You
+;; can edit todo items, reprioritize them within their category, move
+;; them to another category, delete them, or mark items as done and
+;; store them separately from the not yet done items in a category.
+;; You can add new todo files and categories, rename categories, move
+;; them to another file or delete them. You can also display summary
+;; tables of the categories in a file and the types of items they
+;; contain. And you can build cross-categorial lists of items that
+;; satisfy various criteria.
+
+;; To get started, load this package and type `M-x todo-show'. This
+;; will prompt you for the name of the first todo file, its first
+;; category and the category's first item, create these and display
+;; them in Todo mode. Now you can insert further items into the list
+;; (i.e., the category) and assign them priorities by typing `i i'.
+
+;; You will probably find it convenient to give `todo-show' a global
+;; key binding in your init file, since it is one of the entry points
+;; to Todo mode; a good choice is `C-c t', since `todo-show' is
+;; bound to `t' in Todo mode.
+
+;; To see a list of all Todo mode commands and their key bindings,
+;; including other entry points, type `C-h m' in Todo mode. Consult
+;; the document strings of the commands for details of their use. The
+;; `todo' customization group and its subgroups list the options you
+;; can set to alter the behavior of many commands and various aspects
+;; of the display.
+
+;; This package is a new version of Oliver Seidel's todo-mode.el.
+;; While it retains the same basic organization and handling of todo
+;; lists and the basic UI, it significantly extends these and adds
+;; many features. This also required making changes to the internals,
+;; including the file format. To convert files in the old format to
+;; the new format, use the command `todo-convert-legacy-files'.
+
+;;; Code:
+
+(require 'diary-lib)
+;; For cl-remove-duplicates (in todo-insertion-commands-args) and
+;; cl-oddp.

+ "Insert a new Todo item into a category.
+This is the function from which the generated Todo item
+insertion commands derive.
+
+The generated commands have mnenomic key bindings based on the
+arguments' values and their order in the command's argument list,
+as follows: (1) for DIARY `d', (2) for NONMARKING `k', (3) for
+DATE-TYPE either `c' for calendar or `d' for date or `n' for
+weekday name, (4) for TIME `t', (5) for REGION-OR-HERE either `r'
+for region or `h' for here. Sequences of these keys are appended
+to the insertion prefix key `i'. Keys that allow a following
+key (i.e., any but `r' or `h') must be doubled when used finally.
+For example, the command bound to the key sequence `i y h' will
+insert a new item with today's date, marked according to the
+DIARY argument described below, and with priority according to
+the HERE argument; `i y y' does the same except that the priority
+is not given by HERE but by prompting.
+
+In command invocations, ARG is passed as a prefix argument as
+follows. With no prefix argument, add the item to the current
+category; with one prefix argument (`C-u'), prompt for a category
+from the current Todo file; with two prefix arguments (`C-u C-u'),
+first prompt for a Todo file, then a category in that file. If
+a non-existing category is entered, ask whether to add it to the
+Todo file; if answered affirmatively, add the category and
+insert the item there.
+
+The remaining arguments are set or left nil by the generated item
+insertion commands; their meanings are described in the follows
+paragraphs.
+
+When argument DIARY is non-nil, this overrides the intent of the
+user option `todo-include-in-diary' for this item: if
+`todo-include-in-diary' is nil, include the item in the Fancy
+Diary display, and if it is non-nil, exclude the item from the
+Fancy Diary display. When DIARY is nil, `todo-include-in-diary'
+has its intended effect.
+
+When the item is included in the Fancy Diary display and the
+argument NONMARKING is non-nil, this overrides the intent of the
+user option `todo-diary-nonmarking' for this item: if
+`todo-diary-nonmarking' is nil, append `diary-nonmarking-symbol'
+to the item, and if it is non-nil, omit `diary-nonmarking-symbol'.
+
+The argument DATE-TYPE determines the content of the item's
+mandatory date header string and how it is added:
+- If DATE-TYPE is the symbol `calendar', the Calendar pops up and
+ when the user puts the cursor on a date and hits RET, that
+ date, in the format set by `calendar-date-display-form',
+ becomes the date in the header.
+- If DATE-TYPE is a string matching the regexp
+ `todo-date-pattern', that string becomes the date in the
+ header. This case is for the command
+ `todo-insert-item-from-calendar' which is called from the
+ Calendar.
+- If DATE-TYPE is the symbol `date', the header contains the date
+ in the format set by `calendar-date-display-form', with year,
+ month and day individually prompted for (month with tab
+ completion).
+- If DATE-TYPE is the symbol `dayname' the header contains a
+ weekday name instead of a date, prompted for with tab
+ completion.
+- If DATE-TYPE has any other value (including nil or none) the
+ header contains the current date (in the format set by
+ `calendar-date-display-form').
+
+With non-nil argument TIME prompt for a time string, which must
+match `diary-time-regexp'. Typing `<return>' at the prompt
+returns the current time, if the user option
+`todo-always-add-time-string' is non-nil, otherwise the empty
+string (i.e., no time string). If TIME is absent or nil, add or
+omit the current time string according as
+`todo-always-add-time-string' is non-nil or nil, respectively.
+
+The argument REGION-OR-HERE determines the source and location of
+the new item:
+- If the REGION-OR-HERE is the symbol `here', prompt for the text of
+ the new item and, if the command was invoked with point in the todo
+ items section of the current category, give the new item the
+ priority of the item at point, lowering the latter's priority and
+ the priority of the remaining items. If point is in the done items
+ section of the category, insert the new item as the first todo item
+ in the category. Likewise, if the command with `here' is invoked
+ outside of the current category, jump to the chosen category and
+ insert the new item as the first item in the category.
+- If REGION-OR-HERE is the symbol `region', use the region of the
+ current buffer as the text of the new item, depending on the
+ value of user option `todo-use-only-highlighted-region': if
+ this is non-nil, then use the region only when it is
+ highlighted; otherwise, use the region regardless of
+ highlighting. An error is signalled if there is no region in
+ the current buffer. Prompt for the item's priority in the
+ category (an integer between 1 and one more than the number of
+ items in the category), and insert the item accordingly.
+- If REGION-OR-HERE has any other value (in particular, nil or
+ none), prompt for the text and the item's priority, and insert
+ the item accordingly."

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

-(defun todos-basic-insert-item (&optional arg diary nonmarking date-type time
- region-or-here)
- "Insert a new Todo item into a category.
-This is the function from which the generated Todos item
-insertion commands derive.
-
-The generated commands have mnenomic key bindings based on the
-arguments' values and their order in the command's argument list,
-as follows: (1) for DIARY `d', (2) for NONMARKING `k', (3) for
-DATE-TYPE either `c' for calendar or `d' for date or `n' for
-weekday name, (4) for TIME `t', (5) for REGION-OR-HERE either `r'
-for region or `h' for here. Sequences of these keys are appended
-to the insertion prefix key `i'. Keys that allow a following
-key (i.e., any but `r' or `h') must be doubled when used finally.
-For example, the command bound to the key sequence `i y h' will
-insert a new item with today's date, marked according to the
-DIARY argument described below, and with priority according to
-the HERE argument; `i y y' does the same except that the priority
-is not given by HERE but by prompting.
-
-In command invocations, ARG is passed as a prefix argument as
-follows. With no prefix argument, add the item to the current
-category; with one prefix argument (`C-u'), prompt for a category
-from the current Todos file; with two prefix arguments (`C-u C-u'),
-first prompt for a Todos file, then a category in that file. If
-a non-existing category is entered, ask whether to add it to the
-Todos file; if answered affirmatively, add the category and
-insert the item there.
-
-The remaining arguments are set or left nil by the generated item
-insertion commands; their meanings are described in the follows
-paragraphs.
-
-When argument DIARY is non-nil, this overrides the intent of the
-user option `todos-include-in-diary' for this item: if
-`todos-include-in-diary' is nil, include the item in the Fancy
-Diary display, and if it is non-nil, exclude the item from the
-Fancy Diary display. When DIARY is nil, `todos-include-in-diary'
-has its intended effect.
-
-When the item is included in the Fancy Diary display and the
-argument NONMARKING is non-nil, this overrides the intent of the
-user option `todos-diary-nonmarking' for this item: if
-`todos-diary-nonmarking' is nil, append `diary-nonmarking-symbol'
-to the item, and if it is non-nil, omit `diary-nonmarking-symbol'.
-
-The argument DATE-TYPE determines the content of the item's
-mandatory date header string and how it is added:
-- If DATE-TYPE is the symbol `calendar', the Calendar pops up and
- when the user puts the cursor on a date and hits RET, that
- date, in the format set by `calendar-date-display-form',
- becomes the date in the header.
-- If DATE-TYPE is a string matching the regexp
- `todos-date-pattern', that string becomes the date in the
- header. This case is for the command
- `todos-insert-item-from-calendar' which is called from the
- Calendar.
-- If DATE-TYPE is the symbol `date', the header contains the date
- in the format set by `calendar-date-display-form', with year,
- month and day individually prompted for (month with tab
- completion).
-- If DATE-TYPE is the symbol `dayname' the header contains a
- weekday name instead of a date, prompted for with tab
- completion.
-- If DATE-TYPE has any other value (including nil or none) the
- header contains the current date (in the format set by
- `calendar-date-display-form').
-
-With non-nil argument TIME prompt for a time string, which must
-match `diary-time-regexp'. Typing `<return>' at the prompt
-returns the current time, if the user option
-`todos-always-add-time-string' is non-nil, otherwise the empty
-string (i.e., no time string). If TIME is absent or nil, add or
-omit the current time string according as
-`todos-always-add-time-string' is non-nil or nil, respectively.
-
-The argument REGION-OR-HERE determines the source and location of
-the new item:
-- If the REGION-OR-HERE is the symbol `here', prompt for the text of
- the new item and, if the command was invoked with point in the todo
- items section of the current category, give the new item the
- priority of the item at point, lowering the latter's priority and
- the priority of the remaining items. If point is in the done items
- section of the category, insert the new item as the first todo item
- in the category. Likewise, if the command with `here' is invoked
- outside of the current category, jump to the chosen category and
- insert the new item as the first item in the category.
-- If REGION-OR-HERE is the symbol `region', use the region of the
- current buffer as the text of the new item, depending on the
- value of user option `todos-use-only-highlighted-region': if
- this is non-nil, then use the region only when it is
- highlighted; otherwise, use the region regardless of
- highlighting. An error is signalled if there is no region in
- the current buffer. Prompt for the item's priority in the
- category (an integer between 1 and one more than the number of
- items in the category), and insert the item accordingly.
-- If REGION-OR-HERE has any other value (in particular, nil or
- none), prompt for the text and the item's priority, and insert
- the item accordingly."
