* parse_{date,time}(): Split out date/time validationLukas Fleischer2013-02-272-3/+25
| | | | | | | | Split date/time validation into separate functions check_date() and check_time(). These will be used to validate date/time information when reading items from the appointments file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* date_sec2date_str(): Add missing semicolonLukas Fleischer2013-02-191-1/+1
| | | | | | Regression introduced in a363cb9b9111aed22d105adb0e7a8e9caab9bbe3. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix braces in if-else statementsLukas Fleischer2013-02-1720-132/+172
| | | | | | | | | | From the Linux kernel coding guidelines: Do not unnecessarily use braces where a single statement will do. [...] This does not apply if one branch of a conditional statement is a single statement. Use braces in both branches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-1412-126/+126
| | | | | | | | | This unit belongs to the presentation layer -- rename the file accordingly. Also, rename calendar_*() to ui_calendar_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Rename appointment/event-related UI functionsLukas Fleischer2013-02-145-29/+29
| | | | | | | | | * Rename "interaction.c" to "ui-day.c" since it no longer contains todo-related UI functions. * Rename appointment/event-related UI functions to ui_day_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split out UI functions for todo itemsLukas Fleischer2013-02-145-111/+150

| * Close key binding window when reassigning the same keyMichael Smith2013-02-041-0/+6
| | | | | | | | | | | | | | | | | | | | This allows for canceling a key reassignment. We cannot use a static key here since every key could potentially be used in a binding. Instead, just cancel if we are trying to reassign a key that has already been used for that action before.

| * Do not prompt for a todo after adding an appointmentLukas Fleischer2013-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | We effectively turned the addition of an appointment into a fall through case by deleting the break statement during refactoring. Revert this deletion to skip the second prompt. Regression introduced in f2dca7de3e8b164a4b3af3d58dde2f6776bfbee6. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Skip duration update if the prompt is canceledLukas Fleischer2013-02-011-2/+2
| | | | | | | | | | | | | | | | | | Do not update an appointment's duration if the user cancels the prompt at day_edit_duration(). Note that day_edit_duration() does not touch the buffer if the prompt was canceled or an invalid value was entered, resulting in the buffer variable being uninitialized in these cases.

| | | | | | | | | | | | | | Instead of converting everything to upper case and then using strncmp(), use strncasecmp() which does case-insensitive comparison out of the box. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* do_storage(): Unset highlighted item if list is emptyLukas Fleischer2012-12-161-2/+6
| | | | | | | | | Check if the appointment panel contains any items and unset the highlight counter if it doesn't. Not doing this resulted in core dumps if the edit command was invoked after switching to a day without any appointments/events. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Add hidden key handler windowLukas Fleischer2012-12-1610-31/+41
| | | | | | | | | | | | | | | | | | | | | | | | | After BUG#6 had apparently been closed with the screen locks introduced in commit a80f8dcf2c6eb3b54658218bc081ee9694204dd5, some people still had problems with random characters appearing in the notification bar. This was obviously caused by wgetch() refreshing the screen if the status panel was changed. From wgetch(3): If the window is not a pad, and it has been moved or modified since the last call to wrefresh, wrefresh will be called before another character is read. Since the wgetch(3) isn't thread-safe, there were race conditions between the notification bar thread drawing to the notification bar and wgetch() updating the screen. Introduce a (hidden) window that handles all key presses and never gets changed in order to avoid this. Also, call wins_wrefresh() explicitly in status_mesg(), since we can no longer rely on wgetch() updating windows automatically. Fixes reopened BUG#6. Note that this is a hotfix -- FR#26 has been opened to ensure we fix this properly in the next major release. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* wins_show(): Fix size of the slave window arrayLukas Fleischer2012-12-061-1/+1
| | | | | | | | | | | The slave window array was just big enough to hold a single element, whereas two elements are written/accessed. Fix this off-by-one error in the array declaration. Note that this messed up the panel layout when using clang as a compiler. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* io_load_keys(): Skip legacy entryLukas Fleischer2012-12-051-0/+5

* keys_save_bindings(): Skip unset key bindingsLukas Fleischer2012-12-051-2/+6

Before, it was possible that resizing the window during editor/pager mode resulted in the calcurse main screen appearing on top. Addresses BUG#9.

* | Add compact panels supportLukas Fleischer2012-11-257-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a configuration option that allows for switching to compact panel mode. In this mode, all window labels are hidden, so that there's more space for actual information. This patch doesn't add a configuration menu entry and doesn't add any documentation. Implements FR#7.

| * Release screen mutex if thread diesLukas Fleischer2012-11-234-32/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We did not setup a thread cleanup procedure which resulted in calcurse freezing if a thread tried to draw on the screen after another thread was canceled while locking the screen. Note that this kind of cleanup handlers should be added to other mutexes as well. This patch just removes the most common case of triggering a deadlock. Also note that we cannot move pthread_cleanup_push() and pthread_cleanup_pop() into the locking/unlocking functions since both pthread_cleanup_push() and pthread_cleanup_pop() may be implemented as macros that must be used in pairs within the same lexical scope.

| * Lock screen when drawing on the calendar/notification panelLukas Fleischer2012-11-234-3/+61
| | | | | | | | | | | | | | | | | | | | | | | | Lock the screen if either the calendar panel or the notification bar is updated to avoid race conditions. Addresses BUG#6. Note that we currently always use a screen-level lock, even if only one window is affected. This is to be changed in the future. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * Do not display a mark when files are auto-savedLukas Fleischer2012-11-232-23/+2
| | | | | | | | | | | | | | | | | | | | This is kind of useless since users are not able to react to an auto-save notification. It also causes all kinds of problems if the status bar is in a non-standard mode (message, prompt, ...) and is prone to race conditions if the status bar is updated by another thread at the same time.

| * Replace localtime() with localtime_r()Lukas Fleischer2012-11-2210-126/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the result of localtime() is stored in a statically allocated structure, data was overwritten when a context switch occurred during (or shortly after) the execution of localtime(), potentially resulting in critical data corruption. BUG#7 and BUG#8 are likely related. This patch converts all usages of localtime() with localtime_r(), which is thread-safe.
