* Add week numbers in the calendar and full first and last weekLars Henriksen2019-05-225-96/+165
| | | | | | | | | | | | | | | | | | | | | | | | | 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 It has been replaced by the year day number of the selected day.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 Henriksen2019-05-224-21/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-224-85/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-226-49/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-226-44/+15
| | | | | | | | | | | 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.

* 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.

* Refactor listbox codeLars Henriksen2019-05-223-40/+49
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Henriksen2019-05-224-24/+16
| | | | | | | | | | | | | | | | | | | 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.

* Impossible dates in recurrence rulesLars Henriksen2019-05-201-0/+12
| | | | | | | | | | | | | | | According to RFC 5545 dates like 30 February and 31 June must be ignored when derived from a recurrence rule. calcurse relies on mktime() "normalization" of dates (e.g. turning 32 December 2019 into 1 January 2020 when moving from 31 December to the next day). Normalization may also lead to impossible dates in monthly and yearly recurrence rules, and this must be avoided.

* Fix display of time left before next appointmentLars Henriksen2019-04-132-7/+12
| | | | | | | | | | | | | | | | | | In the notify bar, the clock is shown in hours, minutes and seconds, whereas the time left to the next appointment is shown in hours and minutes only. When you read the clock in hours and minutes (discarding the seconds), you are mentally rounding down to the nearest minute. To agree with that reading, the time left (in seconds) should be (programmatically) rounded up to the nearest minute for display. In that way the time left is counted down whenever the minute "hand" of the clock "ticks", and reaches zero when the clock reaches the time of the next appointment, not one minute before. Also, the clock (in hours and minutes) and the time left always add up to the time of the next appointment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Recurring appointments do not show up in the notification bar as next appointment. This was partly corrected by 2084f35 (Fix notification of recurrent appointments, 2017-02-09) and 5aa7a09 (Fix another error in the notification code, 2017-02-11). The search function recur_apoint_starts_before() had a wrong second argument, but is really of no use: the start time of a recurring appointment is the start time of the very first occurrence (in the past). A comparison against the item in the notify_app structure tells nothing of the start time of the current day; at most it eliminates some future recurring appointments. The function can be dropped, and the entire recurring appointment list looked through. The proper start time is found in the main search loop (and called real_recur_start_time) and must be compared against the item in the notify_app structure. But because recur_apoint_find_occurrence() is limited to a particular day (second argument), two searches are necessary to cover 24 hours.

After commit 05e0fd0 "Quit, autosave and interactive save" you could not leave calcurse in read-only mode with the quit command because the key_generic_quit() function interpreted IO_SAVE_CANCEL as a decision (by the user) to cancel a save-conflict and cancelled the quit as well.

* CLI: filter options have no effect for dates before the epochLars Henriksen2019-01-073-16/+16
| | | | | | | | | | | | | | | | With the exception of filter.type_mask, a filter is only applied if set explicitly on the command line with a filter option. Whether that is the case, is determined by comparison with the initialization value. For date related filters (start_from/to, end_from/to) that is -1, hence the criterion is != -1, not >= 0. In generel, a filter initialization value should be invalid (i.e. one that cannot be set explicitly). As times before the epoch (1 January 1970 00:00:00 UTC) are negative, -1 is a valid Unix time. However, as it cannot be set from the command line, it is probably no problem? Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* CLI: time assignments for filter optionsLars Henriksen2019-01-071-4/+21
| | | | | | | | | | | | | | | | | | | | | Explanation. There is an important difference between "to <date>" (e.g. to 15/11/2018) and "to <date time>" (e.g. to "15/11/2018 13:30"): <date> is a time span (of 24 hours), while <date time> is a point in time. "To <date>" really means "to the end of <date>", while "before <date>" means "before the beginning of <date>". There are 24 hours between the two, whereas there is only one second between "before <date time>" and "to <date time>". Similar for from/after. An earlier commit introduced parse_datearg() that only accepts a date without a time. Hence, a date should be treated as a time span from midnight to one second before next midnight. The commit also fixes an error detection bug (filter.start_from/to and filter.end_from/to were updated too early). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* CLI: long options to override configuration file settingsLars Henriksen2019-01-071-3/+29

* CLI: take input date format from configuration file, do not accept timeLars Henriksen2019-01-072-73/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch the input date parsing accepts three formats: yyyy/mm/dd, mm/dd/yyyy, yyyy-mm-dd. They are tried in sequence. It also accepts an additional time (hh:mm), or a time without a date. There are several issues with this: - it is not documented - the date format dd/mm/yyyy is not accepted - print_date() and filter option settings (in parse_args()) can only handle midnight times (which are the result of a date without time) - it is highly uncertain what happens if a time (without a date) is given; at least the -d option treats a time without colon (1215 for 12:15) as a number It seems that acceptance of time input is a by-product and not needed. For these reasons the input date parsing has been changed: - the format is taken from the configuration file (as is the case for the output date format) - only a date, and no time, is accepted Because the input date format is used during parsing of the command line, the configuration file must be loaded first, i.e. the options -D or -C must be parsed before the remaining ones. Loading the configuration file may result in errors (e.g. caused by changes between versions). For this reason config_load() has been made more tolerant and issues warnings instead of exiting. A followup patch will introduce two options to allow the configuration file settings to be overridden for input and output date formats.

* Fix day range for queriesLars Henriksen2019-01-071-8/+6
| | | | | | | | | | | | | | | | In "--from a --to z", a is included in the range, z not. This is non-intuitive and disagrees with the semantics of "to" in filter options like --filter-start-to, where "to" (and "from") are used inclusively (as opposed to "before" and "after"). It also has the effect that "--from today --to tomorrow" has a range of 1 day, "--to z" a range of 0 days (otherwise not allowed), and "--to today --days -1" is allowed and displays yesterday! The implementation has been fixed to agree with "inclusive" semantics. Options --from and -days with negative range are allowed, while --to and --days are disallowed also when the range is negative.

* Rewrite of io_init()Lars Henriksen2018-12-144-97/+60
| | | | | | | | | | | | | | The introduction of the "-C <confdir>" option is an opportunity to review the initialization of data paths. It lead to a rewrite. Two "root" directories are used (data and configuration files); by default they are identical. The statically allocated path buffers are turned into dynamically allocated buffers. Missing files/directories now include hooks. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* DST fix: daylength v. DAYINSECLars Henriksen2018-11-104-3/+9
| | | | | | | | | | | | | | | 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(). Wrong daylength prevented appointments from being stored in the day vector and caused them to be displayed wrongly in the appts panel. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* DST fix: adjusting time in appointmentsLars Henriksen2018-11-104-13/+39
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
