* Check that note files open before reading themNicholas Johnson2023-01-311-0/+8
| | | | | | | | | | | This fixes the scenario where a note file referenced by a todo, event, or appointment is modified from outside the program in such a way that it cannot be opened by the program, resulting in a segmentation fault.

* Treat recurrent events and appointments alikeLars Henriksen2020-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | The day vector (or "day_items" vector) is used to load the appointments panel with "day_items" (captions, appointments, events). A multi-day appointment has several "day_items" in the day vector. This may also be the case for a recurring item. The day_item structure has a member "start", which for day_items for recurring appointments is set to the occurrence found by recur_item_find_occurrence(), and is used to tell days of a multi-day appointment apart. For day_items for recurring events it was set to "day" of the recur_event structure (the same value for all occurrences) and not used. The value is now the occurrence found by recur_event_find_occurrence(). The patch is backwards compatible and future-proof.

| | | | | | | | | | | | Instead of having the user tell how many days to load, calcurse can calculate an overestimation from the running configuration (panel size, appearance of headers and separators etc.) The configuration variable conf.multiple_days is turned into a Boolean that switches the feature on and off.

* Derive selected day from selected itemLars Henriksen2019-05-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add configuration variables for multiple daysLars Henriksen2019-05-221-4/+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.

* Add week numbers in the calendar and full first and last weekLars Henriksen2019-05-221-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-21/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-30/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-221-24/+1

* Fix initialization of the day_items vectorLars Henriksen2019-05-221-0/+1
| | | | | | | | | | | | | | | | This patch fixes all failings tests, but one, in PR #193. Until now the missing initialization of day_items_nb has caused no problems, because the variable was assigned to (=) before being used. In the Multiple days implementation it is repeatedly increased (+=) in a loop without being initialized first. Indeed, this may considered an easily fixed bug. But the initialization really belongs in day_init_vector() so that the call day_item_count(0) returns 0 if done right after the call day_init_vector(). The bug only shows up in command line mode because day_items_nb is not used in interactive mode.

| | | | | | | | | | | | | | | The number of seconds in a day and daylength in seconds differ when Daylight Saving Time is in effect on two days of the year. The day when DST takes effect is 23 hours long, and the day when DST ends is 25 hours long. In the latter case the date changing thread wóuld enter a loop in the last hour before midnight (in the former it would set the date an hour too late). The next midnight is calculated through mktime(), invoked by date2sec().
