* Allow undefined actions in keys configuration fileLars Henriksen2021-04-111-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the keys file there are three possibilities for each action: 1. One or several keys are assigned to it 2. It is marked as UNDEFINED (new) 3. It is missing from the file On load of the keys file, calcurse respectively 1. Assigns the key(s) 2. Assigns "UNDEFINED" (new) 3. Assigns a default key if possible If default keys were assigned, the user is informed of the number of actions affected, and the keys file is updated. After load each action must either have keys assigned or be undefined. If not, calcurse exits with a failure. If there are syntax/semantic errors in the file, calcurse rejects the file and exits. When an interactive user leaves the keys configuration menu, a warning is issued if any action is UNDEFINED. The keys file is always updated. Addresses GitHub issue #298.

* Update import of basic recurrence rulesLars Henriksen2020-06-131-0/+1
| | | | | | | | | | | | | | | | | | | Conversion of COUNT to UNTIL was a simple calculation which assumed one repetiton per period (day, week, month or year); it does not take exception days and invalid dates into account. Solved by a new function which returns the n'th occurrence of a recurrence rule. In calcurse UNTIL is interpreted as a day (DATE), in RFC 5545 as a time of day (DATE-TIME). This has implications when a recurrence rule has an occurrence on the UNTIL day, see comment in ical.c An "Import:" note is added when a multi-day event is imported and turned into a calcurse all-day event.

* User interface for recurrence rulesLars Henriksen2020-04-281-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | The function update_rept() is extended with editing of the three recurrence rule lists for BYMONTH, BYMONTHDAY and BYDAY. The integers of the bymonth and bymonthday lists are edited directly as integers, while those of the bywday list are mapped to localized weekday names (as they appear in the calendar panel) with an optional integer prefix (in RFC5545 style: 1MO, -2SA). The RFC5545 (icalendar) requirement that the start day must be the first occurrence and must match the recurrence rule, is met by testing that an occurrence indeed appears on the start day, in these circumstances: - when a recurrent item is loaded from file - when the recurrence rule of an item is edited interactively - when a recurrent appointment gets a new start time - when a recurrent appointment is moved Copy and paste of a recurrent item will only retain the basic recurrence properties of type, frequency, until and exception days.

* Recurrence rule extensionsLars Henriksen2020-04-281-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Terms and concepts are from RFC 5545 (the iCalendar specification). Overall design -------------- Calcurse is extended with full support for BYMONTH, BYDAY and BYMONTHDAY recurrence rule (rrule) parts. The three rule parts are lists of, respectively, months, weekdays and monthdays. The lists are added to 'struct rpt' as linked lists of integers, and the data file format is extended accordingly (details below). Load and save of the lists follow the pattern of the existing list of exception dates, also in 'struct rpt'. The function recur_item_find_occurence() is split into a front-end and a back-end. The back-end, called find_occurrence(), is the original function extended with rrule reductions; the front-end retains the original name and performs rrule expansions. Front-end plus back-end are backwards compatible and require no changes in calling functions. There is no user interface in this patch. Data file extensions -------------------- The BYMONTH, BYDAY and BYMONTHDAY lists are added to that part of an item line which describes the recurrence rule (the "{...}" part). Each list is - like the list of exception days - a space-separated string of values identified by the initial character. Each list is optional and, if present, must follow the until date and precede the exception day list. The lists must appear in order BYMONTHDAY list, BYDAY list and BYMONTH list. The possible list values are - BYMONTH: m1, m2, ..., m12 - BYDAY: w0, w1, ..., w6, w7, w-7, w8, w-8, ..., w377, w-377 - BYMONTHDAY: d1, d2, ..., d31, d-1, d-2, ..., d-31 which are interpreted as (cf. RFC 5545) - BYMONTH: January, February, ..., December. - BYDAY: SU, MO, ..., SA, +1SU, -1SU, +1MO, -1MO, ..., +53SA, -53SA - BYMONTHDAY: the first, the second, ..., the 31st, the last, the last but one, ..., the last but 30 day of the month Examples: Thursday, TH, is w4; Saturday, SA, is w6. The seventh Thursday, +7TH, is w53 (7 * 7 + 4 = 53); the last but second Saturday, -2SA, is w-20 (2 * 7 + 6 = 20); the last day of the month is d-1. Note that the values w-1, w-2, ..., w-6 are not used. A recurrent appointment with a BYDAY rule part: 06/23/2019 @ 12:00 -> 06/23/2019 @ 13:00 {1W w0 w6} |every week on Sunday and Saturday An event with a BYDAY and a BYMONTH rule part: 10/27/2019 [1] {1Y w-7 m10} every year on last Sunday in October An event with until date, a BYMONTH rule part and an exception day: 06/23/2019 [1] {1Y -> 08/31/2021 m5 m6 m7 !07/23/2020} every year on the 23rd in May, June and July for three years, starting on Sunday, 23 June 2019, but not on 23 July 2020. Recurrence set expansion and reduction --------------------------------------- In calcurse a recurrence rule is a quadruple (s, d, r, e) consisting of start, duration, repetition pattern and exception days and is implemented as: (time_t start, long dur, struct rpt *rpt, llist_t *exc) In RFC 5545 parlance, a recurrence rule defines a recurrence set consisting of all recurrence instances (occurrences) not earlier than start which match the rule pattern. With this concept in mind, recur_item_find_occurremce() may be thought of as a membership function for a recurrence set. The call recur_item_find_occurrence(s, d, r, e, day, occurrence) returns true if day belongs to the recurrence set of (s, d, r, e); if so occurrence points to the recurrence instance (the set member). For a recurrence rule with only the basic DAYLY, WEEKLY, MONTHLY or YEARLY type and frequency the recurrence set consists of periodically repeated instances. The BYxxx rule parts modify the recurrence set by reducing or expanding it as specified by RFC 5545. Expansion is implemented in the front-end by modifications of start and/or frequency of the rule (s, d, r, e), often several times, in such a way that the desired recurrence instances are included in the recurrence set. This is possible because the front-end as the very first thing checks for early days (day < s). When day is known not to be early, start (s) can safely be moved backwards. Likewise, if frequency must be changed, the front-end checks whether the frequency repetition applies to the week, month or year of day. Reduction is easier and is performed in the back-end along with the existing validity checks. It consists in checking whether month, day of month or weekday of a found occurrence is on the appropriate list.

* Refactor edit of exception daysLars Henriksen2020-04-281-1/+3
| | | | | | | | | | | | | | | The patch contains no functional changes, but is a necessary precondition for extensions of update_rept() (in ui-day.c) with further recurrence rules. The reason is that recurrence parameters must be treated as a whole: if an edit session is cancelled at any point, no value should change, and all parameters should remain as they were. Hence, the new values must only be set after all of them have been determined. This was not the case for the list of exception days, but as long as it was treated last, it did not matter.

* Improve data load error reportingLars Henriksen2020-04-281-4/+4
| | | | | | | | | | | The last part of loading appointments and events is performed by four "scan" functions called from io_load_app(). Failure in this part of data load does not use io_load_error().

* Refactor function calls: recurrence parameters as a single argumentLars Henriksen2020-04-281-28/+31
| | | | | | | | | | | | | | | | | | | | | The recurrence parameters are type, frequency, until date and exception list (in RFC 5545 parlance FREQ, INTERVAL, UNTIL and EXDATE's). When these are passed in a function call, the argument list becomes long and not very readable. When support for extended recurrence rules is implemented, the number of recurrence parameters increases, and function signatures must be amended. Solution: The "struct rpt" is extended with the exception list; any future recurrence parameters are added here. A pointer to this structure replaces the recurrence parameters in function calls. Note: Each recurrent event and appoinment instance has (a pointer to) a "struct rpt" and in addition an exception list. The latter is retained to avoid the derived changes, and the exception list in the structure is initialized to an empty list when the recurrent instance is created.

* Derive selected day from selected itemLars Henriksen2019-05-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, with only one day visible at a time, the appointments panel displayed the details of the day selected in the calendar (slctd_day); information required for operations on items (day_items) can often be derived from the selected day. The items available are derived from the selected day. In particular, the selected item is derived from the selected day. With multiple days in the APP panel, the relation between selected day (in the calendar) and the selected item (in the APP panel) has, in a way, been turned around. The selected item may now be moved between days without explicitly changing the selected day. Implicitly it is changed when the target day of a move is unavailable. This commit draws the full consequence: the selected day in the calendar is always (set to) the day of the selected item in the APP panel. The static variable 'struct date slctd_day' lives in ui_calendar.c and is accessible through various public functions. To these are added ui_calendar_set_slctd_day() which sets slctd_day directly. The selected day retains its significance for load of the day vector (in day_store_items()): the range of loaded days begins with the selected day. Movements (up/down) in the APP panel will change the selected day as the selected item moves among the already loaded days. Only when the target of a movement is unreachable, will further days be loaded. On the other hand, if the same range of days must be reloaded because of a changed item, the selected item - and with it the selected day - must be reset to the first day item (see do_storage()). Movements in the calendar (generic-next-day, etc.) are not affected and behave as previously, i.e. they will cause a range of days to be loaded with the selected day as the first and the selected item as the first of the selected day.

With several days in the APP panel, it may be desirable to "squeeze" the entries by leaving out the final empty line of each appointment and lower the number of lines between consecutive days (0, 1, or 2). Both are made general configuration options. To make a uniform display, an empty line is added to a day without appointments, if appointments have an empty line.

* Add week numbers in the calendar and full first and last weekLars Henriksen2019-05-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Much in the calendar is based on the selected day, struct date slctd_day, in ui-calendar.c. On the screen it is highlighted with a deviating colour. The highlight effect has been changed to a pair of red square brackets that do not obscure the day colour. The week number (in the frame) used to be that of the selected day, but has no obvious relation to the days in the APP panel. It has been replaced by the year day number of the selected day. The week numbers of all visible weeks are displayed to the left of the calendar. Dates are displayed also for the overlapping parts of the first and last week of the month (which do not belong to the month). Days are accessible in the appointments panel as well as in the calendar. Hence, validation of days (= inside UNIX time limits) must be extended from the calendar (in ui_calendar_move()) to include loaded days (in day_store_items()).

* Implement scrolling in the appointments panelLars Henriksen2019-05-221-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With multiple days in the APP panel, up/down movements should change behaviour at the top and bottom of the list displayed, and load the previous/next lot of days. This requires that the move function returns the result of the operation. Furthermore, the ability to move the selection to the beginning of a day is needed when moving down (in order to move from the first day to the last day). For this reason a DAY_SEPARATOR has been inserted also after the last day of a lot. Appointments have a listbox height of three to separate them clearly when there is more than one in a day. This leaves a spurious empty line at the end of a day with appointments. The DAY_SEPARATOR height is reduced from two to one, and a new EMPTY_SEPARATOR of height one is inserted in any day with only events. When scrolling up the DAY_HEADING becomes visible when the selection reaches the first item of the day. The length of the separator (between events and appointments) is adjusted to leave a space to the window border at both ends, thereby making it a part of the day, not a separation between days. The dummy event must also be recognisable when not the selected item and is only inserted in interactive mode. The test for a saved selection must also recognise caption items which have item pointer NULL. The function day_get_nb() has been renamed day_get_days().

* Redesign selected-item implementation for the APP panelLars Henriksen2019-05-221-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The day vector, day_items, is displayed in the appointments panel; the selected day_item object is highlighted (when the panel has the focus). When items are inserted, edited, moved etc., and when the day is changed, the day vector is rebuilt and displayed anew. Problem: How shall the selection be set automatically in the context of the new day vector? In previous versions all of the above is mostly handled by the function do_storage() in calcurse.c The function saves data about the selection as needed, rebuilds the day vector, loads the listbox and sets the selection from the saved selection data. This works well in "single day" calcurse in cases where the selected item is present in the day vector both before and after the rebuild, or when the item ordering in the listbox is unaffected by the changes. But when a new item is added the selection cannot be set to the new object by do_storage(). Instead the necessary operations are performed by ui_day_item_add(), and do_storage() is bypassed. In general, when an item cannot be found in the new vector, the item which occupies the old place in the list gets selected, e.g. when an item is deleted. When an item is turned into a repeating one, the old item is deleted and a new is created. Here the new selection is not always the affected item, but in any case not far away. Generally, with only one day in the panel an erronous selection might not be noticed or be accurate by chance. In "multiple day" calcurse the existing scheme works less well; in addition the day vector may now contain more than one object that refer to the same event or appointment (recurrent items or multi-day appointments). The scheme has therefore been modified. The do_storage() function is no longer bypassed, but handles day vector rebuild, load of listbox and item selection exclusively. To make that possible, data about the selected item is no longer saved in a local automatic variable, private to do_storage(), but in an external static variable in day.c, which may be set not only by do_storage(). The variable is declared as static struct day_item sel_data; and used as follows: 1. On startup sel_data is initialized to empty (i.e. no selection). 2. In any operation involving the appointments panel: 2.1 Do the work and if necessary set sel_data. This is the case when deleting, adding or pasting an item, and when turning an ordinary item into a recurrent one. 2.2 Call do_storage(). 3. In do_storage(): 3.1 If sel_data is empty, set it to the current selection. 3.2 Rebuild the day vector. 3.3 Set the selection from sel_data. 3.4 Set sel_data to empty. Further remarks --------------- The selection is found in the new day vector by searching for the saved (order, item.<pointer>) pair. Previously the item.<pointer> alone sufficed and in some cases it still does. In case the item cannot be found, the selection stays in the same day as before the rebuild. An attempt at more consistently named APP-related functions has led to: ui_day_sel_date() replaces ui_day_sel_day() ui_day_get_sel() replaces ui_day_selitem() Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Introduce multiple days in the appointments panelLars Henriksen2019-05-221-3/+10

A listbox consists of a scrollwin (structure) in which a number of items is displayed. The listbox keeps track of: - the number of items - the selected item - the type of each item in an array type[] - the height of each item (ie. how many screen lines) in an array ch[] - how to display an item (on the screen) The latter three are handled by functions fn_type(), fn_height(), fn_draw(). The first two are used to fill in the corresponding array entry, type[] or ch[], for item number i, the third draws item number i. The items are taken from the global variables vector_t day_items int day_items_nb in day.c. Items include captions (DAY_HEADING, DAY_SEPARATOR). Everything is sorted for display (DAY_HEADING, events, DAY_SEPARATOR, appts). These are filled in ("stored") [by day_store_items() for the selected day in the calendar], before being "loaded" into the listbox. See do_storage() in calcurse.c and ui_day_item_add() in ui-day.c. New APP panel design -------------------- Several days are displayed in the APP panel by loading them with day_store_items(). With several days come several headings and separators. DAY_SEPARATOR is reinterpreted to separate days, and a new separator, EVNT_SEPARATOR, separates events from appointments. To sort everything, an 'order' member of type time_t is added to the day_item structure. It is set for headings and separators as well as for appointments and events as follows: item order --------------------- DAY_HEADING BGNOFDAY (= midnight) EVNT_SEPARATOR BGNOFDAY DAY_SEPARATOR ENDOFDAY event start time (midnight) appointment start time (first day) BGNOFDAY (following days, if any) The sort function day_cmp() (used by vector_sort) is extended to sort by order first. The order field always indicates the day to which an item belongs. This comes in handy, because with several days in the APP panel it is necessary to distinguish between the selected day in the calendar and the selected day in the APP panel. This raises the question which day should actions (commands) operate on: the one selected in the calendar or the one selected in the APP panel? Unquestionably the one on the APP panel which is the one tacitly implied. In most cases it is not a problem, though, because actions work on the selected item and the selected day does not come into play. But in some cases it does: delete item When deleting an occurrence of a repeated item, the selected day is the exception day to add. view item day_popup_item() needs the day of the selected item for display of correct start/end times. cut/paste item Paste needs the selected day in which to paste. add item The day of the new item is taken from the calendar. Instead a dummy event is inserted in an empty day. This makes the day selectable, which is otherwise impossible with only the DAY_HEADING displayed. The dummy event is selectable but cannot be edited or deleted (but viewed or piped). With more than one day in the day_items vecter, an appointment spanning more than one day may occur more than once in the vector (with start/end times suitably adjusted for display). A day_item is no longer (always) identified by the aptev_ptr (item) value. Instead the combination (order, item.<ptr>) is used; order is roughly the day.

* Simplify day storageLars Henriksen2019-05-221-2/+1
| | | | | | | | | | | The function day_process_storage() is a wrapper for day_store_items(). It has an unused second argument, and is only used twice to load the selected day. It has been removed. A new function, get_slctd_day(), is the equivalant of get_today() and replaces the very awkwardly named ui_calendar_get_slctd_day_sec(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Refactor listbox codeLars Henriksen2019-05-221-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | The changes are related to the selected item and the visible lines in the scroll window viewport. In particular, the function listbox_fix_visible_region() has been eliminated, and functions previously only called by it have been removed. It performed several tasks that are now elsewhere. One was removed in an earlier commit (scroll window pad improvement). The task of making a multi-line item visible has been moved to listbox_item_in_view(). The task of making a caption line above a text line visible is listbox specific (for the ap_list) and will be moved to ui_day_sel_move(), where it is needed. Boundary checks for the listbox selection have been moved to listbox_fix_sel(). For future use listbox_sel_move() returns success or failure. The function wins_scrollwin_ensure_visible() has been renamed wins_scrollwin_in_view().

* Improve scroll window padLars Henriksen2019-05-221-3/+1
| | | | | | | | | | | | | | | | | | | A scroll window consists of a pad to write on, and a window through which to view the pad, the viewport. The pad may change in size when new contents are loaded into the scroll window. If so, the pad size is set with wins_scrollwin_set_linecount(). But the offset into the pad (the top line to be displayed in the viewport) is not adjusted, although it may not be appropriate for the new pad size. The same is the case when a scroll window is resized and the viewport changes size. This is probably the cause of the problem solved by commit 0b46ad4, Avoid blank space after the last list box item, and the fix has been removed. The wins_scrollwin_set_linecount() has been renamed wins_scrollwin_set_pad() and sets size as well as offset. The offset is only changed if necessary.

* View or edit exception days of a recurrent itemLars Henriksen2019-02-281-0/+2
| | | | | | | | | | | | The exception days are presented for viewing/editing as a string of space-separated dates (in the user-preferred input format). After editing the string is checked for valid dates, but there is no check that a date is meaningful (an occurrence day of the item between start day and until day). Although possible, it is best to add exception days in the usual way by deletion of occurrences.
