* Split online help code into a separate functionLukas Fleischer2013-07-181-0/+3
| | | | | | | Reintroduce help.c and move the online help code into a new function display_help(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rename io_file_exist{,s}()Lukas Fleischer2013-07-171-1/+1

* Drop legacy online help systemLukas Fleischer2013-07-171-4/+0
| | | | | | | | | | Remove the old online help system and change the generic help key to do the same thing as ":help". This also removes some context-sensitive help. We should think about re-adding support for this later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add command promptLukas Fleischer2013-07-171-0/+1
| | | | | | | | | | This adds support for vim-style command mode. The command mode can be entered with pressing ":" (by default, the key binding is configurable). Currently, no command is supported. Support for various commands will be added later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add -l/--limit optionWilliam Pettersson2013-07-161-1/+1
| | | | | | | | Adds the -l/--limit command line option. Limits the number of appointments and/or ToDo items displayed. Signed-off-by: William Pettersson <william.pettersson@gmail.com> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a macro to determine the size of arraysLukas Fleischer2013-05-041-0/+2
| | | | | | | | Use following macro instead of "sizeof(x) / sizeof(x[0])" everywhere: #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0])) Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-222/+227
| | | | | | | | | | | This completes our switch to the Linux kernel coding style. Note that we still use deeply nested constructs at some places which need to be fixed up later. Converted using the `Lindent` script from the Linux kernel code base, along with some manual fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* parse_{date,time}(): Split out date/time validationLukas Fleischer2013-02-271-0/+2
| | | | | | | | 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>
* Mark todo_get_position() publicLukas Fleischer2013-02-141-0/+1
| | | | | | This is needed in "ui-todo.c" now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-141-22/+22
| | | | | | | | | 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>
* todo.c: Split out UI-related functionsLukas Fleischer2013-02-141-13/+13
| | | | | | | * Move UI-related functions to "ui-todo.c". * Rename UI-related functions to ui_todo_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* apoint.c: Split out UI-related functionsLukas Fleischer2013-02-141-7/+7
| | | | | | | * Move UI-related functions to "ui-day.c". * Rename UI-related functions to ui_day_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rename appointment/event-related UI functionsLukas Fleischer2013-02-141-8/+8
| | | | | | | | | * 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 Fleischer2013-02-141-4/+4
| | | | | | | | | * Move todo-related UI functions from "interaction.c" to a new compilation unit "ui-todo.c". * Rename all todo-related UI functions to todo_ui_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Use strncasecmp() for case-insensitive comparisonLukas Fleischer2013-01-301-1/+0
| | | | | | | | | | | | | | 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>

* Add hidden key handler windowLukas Fleischer2012-12-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * Ignore signals during command executionLukas Fleischer2012-11-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Disable signal handlers in wins_prepare_external() and reactivate them in wins_unprepare_external(). Before, it was possible that resizing the window during editor/pager mode resulted in the calcurse main screen appearing on top. Addresses BUG#9.

* | io_check_*()/io_file_exist(): Fix signaturesLukas Fleischer2012-11-261-3/+3
| | | | | | | | | | | | | | This was broken in commit 87fb8cfec0d8e8fc901746095458bd316314b6ee. Fix function signatures and update all invocations accordingly. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add compact panels supportLukas Fleischer2012-11-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add configuration option to set a default panelLukas Fleischer2012-11-251-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows for customizing the panel that is selected by default when calcurse is started. Note that this patch doesn't add any documentation. Also, this configuration option currently cannot be configured using the configuration menu. Implements FR#19. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Remove wins_slctd_init()Lukas Fleischer2012-11-251-1/+0

| * Release screen mutex if thread diesLukas Fleischer2012-11-231-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * Lock screen when drawing on the calendar/notification panelLukas Fleischer2012-11-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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 Fleischer2012-11-231-1/+0
| | | | | | | | | | | | | | | | | | | | 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.

* | Use status_ask_choice() for the export dialogLukas Fleischer2012-11-181-1/+0
| | | | | | | | | | | | | | | | Remove the export bar and use a simple status_ask_choice() dialog instead. This reduces code complexity and replaces another unnecessary menu by the well-tested dialog feature that is used everywhere else. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Remove the erase flag and legacy deletion codeLukas Fleischer2012-07-071-11/+4
| | | | | | | | | | | | | | | | This is no longer needed. Note removal, as well as exception handling, have been moved to separate functions and the cut feature has been merged into the deletion function. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Merge cut/deleteLukas Fleischer2012-07-071-3/+1
| | | | | | | | | | | | | | Remove the cut function and merge it into the del-item command. This allows for vim-style cutting/pasting. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Refactor exception handlingLukas Fleischer2012-07-071-2/+5
| | | | | | | | | | | | | | | | | | Remove the exception handling code from recur_*_erase() and move it to separate functions recur_*_add_exc(). Create a wrapper function day_item_add_exc() that can be used to add an exception to generic items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Refactor note removalLukas Fleischer2012-07-071-1/+1
| | | | | | | | | | | | | | | | Remove the note removal code from *_delete()/*_erase() and create a new wrapper function called day_item_erase_note() that is be used to drop the note being associated to an item. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add support for copy/paste registersLukas Fleischer2012-07-071-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for vim-style copy/paste registers which allows cutting and copying multiple items without having to overwrite the copy/paste buffer. Registers can be specified using the quote key ('"'). To access a register, type '"x' before a command where "x" is the name of a register. If you want to copy the currently selected item into register 1, type '"1c'. Valid registers are 0-9, a-z, "-" and "_". Note that the latter is the so-called black hole register, which works similar to the black hole register in vim. The register prefix key is currently hardcoded and cannot be configured.

* | Implement a cache for the monthly viewLukas Fleischer2012-06-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a very simple cache, which is used to store the days that contain an event or an appointment. This makes redrawing and browsing the calendar panel much faster. The cache has a size of 31 integers (which is equivalent to 124 bytes on a 32 bit system and 248 bytes on a 64 bit system) and invalidates itself if the current month has changed. If an item is added/changed/removed, the cache needs to be invalidated manually by calling calendar_monthly_view_cache_set_invalid(). Note that this will always invalidate the whole cache, even if only one item at the last day of the month was removed. This is a trade-off between simplicity and efficiency.

* | Remove unneeded parameter/return valueLukas Fleischer2012-06-301-2/+2
| | | | | | | | | | | | | | | | The item type parameter/return value no longer needs to be passed/returned to interact_day_item_{paste,cut}(), since the type descriptor is saved when cutting an item now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Revise cut/pastingLukas Fleischer2012-06-301-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of calling type-specific duplication handlers and inserting clones of the original items when pasting, save the generic day item and remove the actual item from the linked list, so that it can be inserted anywhere else later. The cut/paste buffer is moved to the interaction unit, item-specific cut operations are changed to remove the item from the linked list only instead of copying and freeing it. An item is only freed if another item is cut before the current cut/paste buffer is pasted. All paste operations are changed and reinsert the actual item instead of creating a clone.

* | Remove "appt_pos" member from day itemsLukas Fleischer2012-06-301-1/+0
