* DST fix: adjusting time in appointmentsLars Henriksen2018-11-101-5/+23
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* DST fix: adding appointments on the day when DST starts or stopsLars Henriksen2018-11-101-11/+7
| | | | | | | | | | A new apppoint inserted on the day when the clock is adjusted backward by an hour got a wrong start time (an hour late). Reason: mktime() must not use the Daylight Saving Time information returned by localtime_r(). Also editorial simplifications. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Minor merge adjustmentsLars Henriksen2018-08-251-36/+43
| | | | | | | | Comments inserted. Slightly different implementations of parse_time() and parse_datetime(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Start and end time validation.Lars Henriksen2018-08-251-5/+44
| | | | | | | | | | All appointment times are checked for validity. Overflow by time arithmetic is detected. End times are checked when appointments are moved. Three functions are involved: parse_datetime(), parse_duration() and parse_date_duration(); they all have a new argument for validation purposes. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Support UTF-8 encoded characters in user choicesLars Henriksen2018-06-031-12/+23
| | | | | | | | Translations (in po-files) of texts that are used for alternative choices (e.g. [dwmy]), may use UTF-8 encoded Unicode characters (e.g. [éãüå]). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Scrollbar and right window border (corrected)Lars Henriksen2018-05-261-15/+8
| | | | | | | | | | | | | | | | | 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>
* Scrollbar and right window borderLars Henriksen2017-12-101-8/+27
| | | | | | | | | | | | | | | | | | | 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 itself is always highlighted: - when APP or TOD is deselected - in configuration windows where borders otherwise are not The patch moves the scrollbar parameters from arguments of draw_scrollbar() to the function itself. The highlight argument to draw_scrollbar() was always 1. Instead call circumstances are figured out and highlight set accordingly. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Default colour as foreground colourLars Henriksen2017-12-101-0/+6
| | | | | | | | | | | | | In the default colour setup (white on black), white could only with great difficulty be used as customized foreground colour, because the colour pair COLR_CUSTOM then was identical to COLR_DEFAULT (default on default). This made it impossible to distinguish the selected element in lists. The patch turns on the video attribute bold when default is chosen as foreground colour.

* Check for the year span 1902-2037Lars Henriksen2017-11-231-6/+8
| | | | | | | | | | | | | Reintroduce year check for systems with a 32-bit time_t type. Remove the lower limit (1902) for systems with a 64-bit time_t. This limits movements in the calendar (for 32-bit systems) and in no way ensures constistency of data. Commit a12833e (Handle dates past January 19th, 2038, 2015-01-19) removed the upper limit (2037) on dates but left the lower limit (1902). It did not ensure the support of the target system.

* Parse time before date in parse_datetime()Lukas Fleischer2017-10-271-2/+2
| | | | | | | | | Make sure that in cases when the date and time formats conflict, such as is the case with "0030", the input is interpreted as a time value, not a date. Suggested-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make parsing of date-time more strictLukas Fleischer2017-10-261-15/+20
| | | | | | | | | | | In parse_datetime() it was possible to enter any number of dates and times in any order. Allow just date or time or date followed by time. Time must be looked for before date because of conflicting time and date formats. Suggested-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add parse_date_interactive()Lukas Fleischer2017-10-261-0/+7
| | | | | | | | | 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. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Remove phase of moon featureLars Henriksen2017-09-081-2/+0
| | | | | | | | | | The computation never really worked before and it seems like the feature is not very helpful, sometimes even confusing (see GitHub issue #21).

* Add a function to wait for any key pressLukas Fleischer2017-09-031-3/+3
| | | | | | | Introduce a new function keys_wait_for_any_key() and use it instead of wgetch() whenever the return value is discarded. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix empty warning box when key is already in useLars Henriksen2017-08-121-0/+2
| | | | | | | | | | | | When adding a key already in use for another action, a warning box is displayed. The text length is limited by the window width through the use of strncpy(). If the limit is exceeded, the string will have no null termination, resulting in unpredictable behaviour. A similar problem in fatalbox() is fixed as well.

* Support dates when specifying start/end timesLukas Fleischer2016-10-091-2/+6
| | | | | | | | | | 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 Fleischer2016-10-091-0/+39
| | | | | | | | 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>
* Stop all threads before leaving curses modeLukas Fleischer2016-09-131-2/+4

* Add support for UTC times in iCal importsLukas Fleischer2015-02-231-0/+25
| | | | | | | | | | | | | | According to the iCal standard (4.3.12 Time): UTC time, or absolute time, is identified by a LATIN CAPITAL LETTER Z suffix character (US-ASCII decimal 90), the UTC designator, appended to the time value.

* Refactor new_tempfile()Lukas Fleischer2014-07-221-10/+7
| | | | | | | | Avoid preallocating buffers on the stack, use dynamic memory allocation instead. Also, change the semantics of new_tempfile() so that it returns the full name of the temporary file and fix all call sites. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-221-9/+10
| | | | | | | | Use asprintf() in some cold code paths. While allocating memory on the heap is a bit slower, using asprintf() is a bit more memory efficient and less prone to buffer overflow errors. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add vasprintf() and asprintf()Lukas Fleischer2014-07-221-0/+38
| | | | | | | | | The new utils.c functions vasprintf() and asprintf() are analogs to sprintf() and vsprintf(). However, instead of requiring a buffer that is large enough to hold the output data, the functions allocate a string and return a pointer to it.

* Rework scroll window implementationLukas Fleischer2014-05-181-1/+1
| | | | | | | | | | This complete rewrite of the scroll window implementation decouples scroll windows from every other window abstraction layer we use. Note that this leads to some code duplication. The long-term purpose of this rewrite, however, is to eventually make every panel use scroll windows. This makes for a huge cleanup of the UI code.
