* 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>

* Fix seg fault in update_rept()Lars Henriksen2018-08-251-5/+7
| | | | | | | Memory pointers must be initialized at the start in case memory is freed (cleanup) before it is allocated. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Buffer mixupLars Henriksen2018-08-251-4/+3

* Major overhaul of appointment/event input routines.Lars Henriksen2018-08-251-194/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting start time for a new appointment, a date is disallowed (in all other cases both time and date are still allowed). Both date and time are displayed for the user to correct when an appointment is changed or moved. Built-in help in the status bar for display of input formats. Several bug fixes that resulted in data inconsistencies (end time before start time). The routines use the enhanced parsing funtions to validate input: ui_day_item_add(void) parse_datetime() parse_duration() parse_datetime() ui_day_item_repeat(void) parse_date_duration() parse_date() ui_day_item_edit(void) update_start_time() day_edit_time() parse_datetime() update_duration() parse_duration() parse_datetime() update_rept() parse_date_duration() parse_date() Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Refactoring update_duration/day_edit_duration.Lars Henriksen2018-08-251-55/+49
| | | | | | Incorporated day_edit_duraton() into update_duration(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make editing of punctual appointments more intuitiveLukas Fleischer2018-08-251-3/+6
| | | | | | | | | | When editing the start time, move the item instead of keeping the previous start time as end time. When editing the end time, start with an empty end time instead of the previous start time. Fixes GitHub issue #89. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix end-before-start inconsistencyLars Henriksen2018-06-051-7/+9
| | | | | | | | | | | | Due to deficient validation, it is possible to get an inconsistent database with an appointment that ends before it begins. Edit an existing one and specify an end time by a date that precedes the start date, or create a new one and give a date as end time that precedes the start. Then exit calcurse; on restart it will report a data error and exit. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix appointment becoming eventLars Henriksen2018-06-051-4/+4
| | | | | | | | | | | | You try to enter an appointment, but enter an invalid start time (by mistake). Calcurse rejects the input. You enter the correct start time and calcurse asks for the description, not the end time, i.e. you get an event. The check for an event must only be performed on valid input.

* Scrollbar and right window border (corrected)Lars Henriksen2018-05-261-2/+2
| | | | | | | | | | | | | | | | | When a scrollbar is on display in APP or TOD windows, the right vertical border (outside the scrollbar) is not highlighted when the window is selected. The scrollbar is always highlighted: - when APP or TOD is deselected - in configuration windows where borders otherwise are not The patch moves the scrollbar parameters (except highlight) from arguments of draw_scrollbar() to the function itself. The highlight argument was 1; instead it is set higher in the call hierarchy (wins_update_panels()) and passed on down. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add parse_date_interactive()Lukas Fleischer2017-10-261-6/+4
| | | | | | | | | Add a wrapper around parse_date() which picks the current input date format as well as the currently selected day and passes both values to parse_date(), alongside with the parameters passed to parse_date_interactive() itself.

* Make the day heading position configurableLars Henriksen2017-09-081-1/+4
| | | | | | | | | The date at the top of the appointments list may be positioned either to the left, in the middle or to the right. Default is to the right.

* Remove phase of moon featureLars Henriksen2017-09-081-1/+0
| | | | | | | | | | The computation never really worked before and it seems like the feature is not very helpful, sometimes even confusing (see GitHub issue #21). The macro ISLEAP is moved to calcurse.h. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add missing string initializationLars Henriksen2017-09-041-0/+1
| | | | | | | | | | | When introducing the fmt_day_heading() function in commit d56cc7a (Make heading in appointments panel configurable, 2017-08-19), we forgot to initialize the dynamic string. This resulted in calling mem_free() with a garbage pointer, potentially resulting in a segmentation fault. Fix this by calling string_init() before using the string.

* Add a function to wait for any key pressLukas Fleischer2017-09-031-14/+14

* Refactor duration/end time parsingLukas Fleischer2016-10-101-35/+39

| | | | | | | | | | Add support for combined date/time or date-only strings when specifying the start or end time of a new item. This is a follow-up to 1f39b5c (Add support for moving items to another day, 2016-09-30). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Factor out parse_datetime()Lukas Fleischer2016-10-091-25/+5
| | | | | | | | Create a new function that takes a time stamp and updates the date or time components of that time stamp according to a given date/time string. Use that function for updating the start time of an item. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add support for moving items to another dayLukas Fleischer2016-10-081-11/+27
| | | | | | | | | | | | | When moving an item (or when changing the start time of an item), allow for optionally specifying a date. If both date and time are entered, the item is updated to start on the given date and time. If only a date is entered, the item is modified to start on the given date, keeping the current start time. If only a time is entered, the item is modified to start on the current date and the new start time. Fixes GitHub issue #12. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Support relative dates when adding recurrencesLukas Fleischer2016-04-011-13/+31
| | | | | | | | | | | | In commit f5d8b5e (Support durations in recurrence ending dates, 2016-02-25), we added support for the `+xxwxxd` syntax when specifying recurrence end dates. However, this only worked when *editing* the recurrence, not when converting a regular item to a recurrent one. Fix this and support the new syntax in both cases. Also, mention the new syntax in the prompt. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Support durations in recurrence ending datesLukas Fleischer2016-02-261-14/+32
