* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-229-135/+150
| | | | | | | | 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 Fleischer2014-07-222-0/+40
| | | | | | | | | 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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Small code cleanupsLukas Fleischer2014-07-182-20/+16
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use wins_set_bindings() for the configuration menuLukas Fleischer2014-07-183-42/+75
| | | | | | | Make use of the general key binding context switching implementation for the configuration main menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Make bindings always fill the whole status barLukas Fleischer2014-07-181-0/+2
| | | | | | | Compute padding for key bindings in the status bar such that they use all available space (without exceeding the given page size). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Always fix selection in listbox_load_items()Lukas Fleischer2014-07-181-5/+3
| | | | | | | | | | Since commit 80a7267 (Fix selection in listbox_load_items(), 2014-07-18), listbox_fix_sel() is called if the selection is out of range after loading the new set of items. However, we should *always* fix the selection to make sure the selection doesn't move to a caption row when reloading items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not use malloc() or xmalloc()Lukas Fleischer2014-07-183-7/+7
| | | | | | | Use mem_malloc() instead which automatically picks the right implementation depending on whether memory debugging is enabled or not. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not display dialog on periodic saveLukas Fleischer2014-07-181-1/+2
| | | | | | | | When periodic save is enabled, do not print the "The data files were successfully saved" dialog every time io_save_cal() is called. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Initialize prompt buffers in the configuration menusLukas Fleischer2014-07-182-1/+5
| | | | | | | | malloc() does not make sure that the buffer is initialized to contain all zeros. Initialize the buffer with the empty string. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix selection in listbox_load_items()Lukas Fleischer2014-07-181-7/+13
| | | | | | | Call listbox_fix_sel() after setting an initial selection in listbox_load_items() to make sure we do not pick a caption row. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* keys.c: Merge keydef and binding_labelsLukas Fleischer2014-07-171-100/+51
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rework key binding context switchingLukas Fleischer2014-07-175-142/+132
| | | | | | | Store key binding contexts using another data structure to optimize space usage and execution time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Pause notification thread when reloading itemsLukas Fleischer2014-07-171-0/+6
| | | | | | | Prevent the notification thread from accessing data structures for appointments and todo items while we are recreating them. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Only run the merge tool on files with differencesLukas Fleischer2014-07-173-7/+42
| | | | | | | If the backup file and the data file are equal, there is no need to run the merge tool. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Reintroduce key bindings in configuration menusLukas Fleischer2014-07-172-4/+28
| | | | | | | | | | The key bindings display in the status bar was removed from the general options menu in bd182fb (Use generic list box for general options, 2014-05-13) and from the notification options menu in 5eea05a (Use generic list box for notification options, 2014-05-13). Display the new key bindings to use for navigation. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split out code to set bindingsLukas Fleischer2014-07-172-16/+28
| | | | | | | | Split wins_status_bar() into wins_set_bindings(), wins_update_bindings() and wins_status_bar(). This allows for using wins_set_bindings() to set custom key bindings to be displayed. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* wins.c: Drop NB_*_CMDSLukas Fleischer2014-07-171-28/+11
| | | | | | | Store the current number of commands in a static variable and drop the NB_*_CMDS variables which we outdated anyway. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor wins_launch_external()Lukas Fleischer2014-07-166-29/+20
| | | | | | | | Allow for passing an arbitrary number of arguments. This also allows us to remove wins_launch_external2() and use wins_launch_external() at all call sites instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid cancelling the save thread during savingLukas Fleischer2014-07-161-4/+8
| | | | | | | Ensure that we never cancel the periodic save thread when it currently saves the configuration and data files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Allow for merging data files when reloadingLukas Fleischer2014-07-166-18/+97
| | | | | | | | This allows for merging the (unsaved) items with the items from the data files when invoking the reload operation. To this end, an external merge tool (defaults to vimdiff) is used. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a cleanup handler for the notify main threadLukas Fleischer2014-07-161-0/+13
| | | | | | | Make sure we do not leave behind unusable mutexes when calling pthread_cancel(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* day.c: Fix typo in error messageLukas Fleischer2014-07-161-2/+2
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Warn when reloading with unsaved modificationsLukas Fleischer2014-07-165-0/+58
| | | | | | | Since the reload operation overwrites all changes, warn before reloading if there are unsaved modifications. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Automatically select first item in list boxesLukas Fleischer2014-07-161-0/+3
| | | | | | | If the selection is empty during listbox_load_items() and there is at least one item in the list, automatically select the first item. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a key binding to reload appointments and todosLukas Fleischer2014-07-164-25/+49
| | | | | | | This allows for reloading the appointment and todo item files without having to restart calcurse. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Initialize linked list for recurrent itemsLukas Fleischer2014-07-164-0/+8
| | | | | | | | | | When switching to the generic linked list implementation for recurring events in 9fab248 (Use generic lists for recurring apointments and events., 2011-04-16), no initialization routine for the list of recurring events was added. Fix this and properly initialize the list on startup. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Fix SHA1 calculation of long notesLukas Fleischer2014-07-081-1/+5
| | | | | | | | | sha1_update() modifies the input data, so we need to duplicate the input before calculating the hash. Otherwise, input data longer than 64 bytes will be garbled. Reported-by: Hakan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix segmentation faultLukas Fleischer2014-06-254-14/+16
| | | | | | | | | | This adds some more accurate checks to avoid a segmentation fault that occurred when accessing a nonexistent item. Fixes GitHub issue #7. Reported-by: Bromind <martin.vassor@hotmail.fr> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid blank space after the last list box itemLukas Fleischer2014-05-193-0/+19
| | | | | | | Automatically scroll down the list box when resizing creates some blank space below the list of items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Resize panels properlyLukas Fleischer2014-05-194-17/+23
| | | | | | | Rewrite the panel resize code and remove the code that reinitializes the caption and the selected item when the window is resized. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* listbox_resize(): Avoid segmentation faultLukas Fleischer2014-05-191-0/+4
| | | | | | Only try to fix the visible region if an item is selected. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add default cases to some switch statementsLukas Fleischer2014-05-183-5/+26
| | | | | | This squelches several compiler warnings. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* day_item_add_exc(): Fix unwanted fall-throughLukas Fleischer2014-05-181-0/+2
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Reintroduce heading and separator in appointmentsLukas Fleischer2014-05-184-32/+52
| | | | | | | This re-introduces the heading (showing the POM and the current date) as well as the separating line between events and appointments. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add support for caption rows in list boxesLukas Fleischer2014-05-187-16/+105

| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* ui-day: Large-scale refactoringLukas Fleischer2014-05-186-362/+188
| | | | | | | | | | Use the generic list box implementation for the appointments panel. This results in some major changes to how the items are printed. Note that this temporarily removes the heading showing the POM and the date as well as the separating line between events and appointments. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Store appointments for the current day in a vectorLukas Fleischer2014-05-183-19/+21
