* Add configuration variables for multiple daysLars Henriksen2019-05-221-1/+3
| | | | | | | | | | | | | | | The number of days displayed in the APP panel has been made configurable, maximum 21 days, default seven days. 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.

* Implement scrolling in the appointments panelLars Henriksen2019-05-221-8/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-37/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overview of existing implementation ----------------------------------- The APP panel displays the 'day_items' vector in the 'lb_apt' listbox. 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 Henriksen2019-05-221-4/+4
| | | | | | | | | | | 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.

* View or edit exception days of a recurrent itemLars Henriksen2019-02-281-1/+19
| | | | | | | | | | | | 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.

* DST fix: adjusting time in appointmentsLars Henriksen2018-11-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Calcurse saves time and date information on disk as local time in readable text file format. When loaded from disk or when entered by the user, local time is converted to Unix time (seconds since 00:00:00, 1 January 1970). When displayed, and later when saved to disk, the Unix time is converted back to readable local time. Both conversions depend on DST. Hence, if midnight for a day with DST in effect (i.e. local time) is converted, increased with an amount and converted back, the amount has changed if DST is _not_ in effect for the resulting time. In general, calculations on Unix time variables should be used with caution because of the DST-dependent conversions. Instead, the calculations should be performed on local time data with the help of mktime(). The commit fixes start time for pasted appointments (ordinary and recurrent) and the 'until'-date of recurrent appointments, pasted as well as new and edited. The latter problem is slightly different in that the adjustment is a number of days, as it is for exception dates. Update of the date in parse_datetime() has been corrected to be similar to update of the time, although no problem has been identified. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting start time for a new appointment, a date is disallowed (in all other cases both time and date are still allowed).
