2012-12-16do_storage(): Unset highlighted item if list is emptyLukas Fleischer
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>
2012-12-16Add hidden key handler windowLukas Fleischer
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>
2012-11-25Add configuration option to set a default panelLukas Fleischer
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>
2012-11-25Remove wins_slctd_init()Lukas Fleischer
We only call this once. Remove the wrapper and directly call the wrapped function instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18Use status_ask_choice() for the export dialogLukas Fleischer
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>
2012-11-18Remove unused parameter from key handlersLukas Fleischer
This is no longer needed since different keys use different handlers now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18calcurse.c: Pull out key_move_*()Lukas Fleischer
Supersedes the "key" parameter from following functions: * key_generic_prev_day() * key_generic_next_day() * key_generic_prev_week() * key_generic_next_week() Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18calcurse.c: Break up key_change_priority()Lukas Fleischer
Split up key_change_priority() into key_raise_priority(), key_lower_priority() which are wrappers around a new convenience function change_priority(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18calcurse.c: Pull out key_generic_goto_today()Lukas Fleischer
Split out key_generic_goto_today() into a separate function. This simplifies the control flow and supersedes the "key" parameter in key_generic_goto(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18Refactor todo_chg_priority()Lukas Fleischer
Instead of passing a key, pass the number of steps to increase the priority by. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18calcurse.c: Refactor the main loopLukas Fleischer
Break up the big switch statement into several functions. The functions are declared inline to avoid unnecessary function calls. Also: * Add a "KEY_HANDLER" macro can be used as a short version of a "case" statement, followed by a function call. * Declare several state variables global to avoid having to pass them to each of the new handlers. * Pass the pressed key to each of the handler functions in order not to break handlers that handled more than one key before the handlers were pulled out. These three changes were introduced to keep this patch as atomic as possible and are intended to be removed in following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-07-07Merge cut/deleteLukas Fleischer
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>
2012-07-07Add support for copy/paste registersLukas Fleischer
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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-07-06Add a key binding for generic-copyLukas Fleischer
This finally adds full copy-paste support. Implements FR#15. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Implement a cache for the monthly viewLukas Fleischer
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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Remove unneeded parameter/return valueLukas Fleischer
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>
2012-06-30Move apoint_{cut,paste}() to interaction unitLukas Fleischer
These functions get the current selection, call day_*_item() and fix the current selection on the appointment panel, so move them where they belong. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Add an item parameter to various todo_*() functionsLukas Fleischer
These functions operate on arbitrary items. Pull out the code that gets the currently selected item, get the current selection when one of the functions is called and pass it as a parameter. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Add an item parameter to various day_*() functionsLukas Fleischer
These functions operate on arbitrary items. Pull out the code that gets the currently selected item, get the current selection when one of the functions is called and pass it as a parameter. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Rename interaction functionsLukas Fleischer
Rename all interaction functions for the sake of consistency and add a "interact_" prefix. Also, mark day_erase_item() static since it is not used anywhere else. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-30Simplify apoint_switch_notify()Lukas Fleischer
Pull out code from apoint_switch_notify() -- especially the fallback routine that calls recur_apoint_switch_notify() if the currently selected item is a recurrent item -- and move it to a wrapper function day_item_switch_notify(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-13Add key bindings to go to the previous/next month/yearLukas Fleischer
In addition to generic key bindings for moving one day (week) forward/backward, define similar bindings for moving a month or a year. Of course, count prefixes are allowed here as well. Also add status bar hints and help texts. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-13Rename displacement enumeration elementsLukas Fleischer
* Rename "LEFT" to "DAY_PREV", "RIGHT" to "DAY_NEXT", "UP" to "WEEK_PREV" and "DOWN" to "WEEK_NEXT" to reflect the semantics of these operations. Remove the unneeded "MOVES" element. * Reorder code to improve consistency. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-21Switch to Linux kernel coding styleLukas Fleischer
Convert our code base to adhere to Linux kernel coding style using Lindent, with the following exceptions: * Use spaces, instead of tabs, for indentation. * Use 2-character indentations (instead of 8 characters). Rationale: We currently have too much levels of indentation. Using 8-character tabs would make huge code parts unreadable. These need to be cleaned up before we can switch to 8 characters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-14Factorize boolean user prompting.Baptiste Jonglez
Introduce a new `status_ask_bool()` function, and use it where applicable. This greatly reduces code duplication, and will allow handling special events (resize, user escape) much more uniformely. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-04-12src/calcurse.c: Start all helper threads in one goLukas Fleischer
Makes our initialization code a tad cleaner and seems to reduce flicker when starting calcurse (the notification bar is no longer drawn before other windows are shown). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-04-12Refactor startup screen branchLukas Fleischer
Removes the pointless first parameter to io_startup_screen() and saves one wins_update() call if system dialogs are disabled. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-04-05Mark localized string literals constantLukas Fleischer
Translated strings returned by gettext() are statically allocated and shouldn't be modified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-03-29Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer
These were renamed from "skip_"* to *. However, we only changed syntax and didn't invert their semantic meaning. Fix this by negating the semantics of those variables. Also, negate these in the configuration file automatically when running `calcurse-upgrade`. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-03-26Update copyright rangesLukas Fleischer
Add 2012 to the copyright range for all source and documentation files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-03-02Break out configuration main menuLukas Fleischer
This was the only big block of code left in our main loop. Move it to a separate function, making the main loop a bit clearer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-12-09Extract config file handlers into a separate fileLukas Fleischer
We used custom_load_conf() to load the configuration file and io_save_conf() to save configuration. Move these functions, including all helpers, to a central location. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-11-14Use a global configuration variableLukas Fleischer
This is one of the few valid use cases for a global variable. No need to make it pseudo-local and pass it from one function to another. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06src/calcurse.c: Support count prefixes for motionsLukas Fleischer
Add a global count buffer to our main loop and pass it to keys_getch() as well as to all motion commands. This enables some fancy shortcuts: * Type "2l" to jump to the day after tomorrow. * Type "4k" (or "28l") to move forward four weeks. * Type "2$" to go to the end of next week. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Add count buffer to keys_getch()Lukas Fleischer
Key commands can be prefixed with a natural number - keys_getch() will store this number in the buffer pointed to by the second parameter. Set this parameter to NULL to disable count prefixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Add count parameter to *_{in,de}crease()Lukas Fleischer
This allows for moving more than one item up/down. This currently isn't used anywhere but will be bound to a key with one of the following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06src/calendar.c: Add a count parameter to calendar_move()Lukas Fleischer
Allows for moving more than one step forward/backward. This is not used anywhere yet but a key binding will likely be added in one of the following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Avoid unnecessary window updatesLukas Fleischer
Add a window bitmask to wins_update() and only update windows that might actually require an update in our main loop. This improves response times of the user interface a bit. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Refactor out storage updatesLukas Fleischer
Instead of using a hacky flag, simply move the storage update code to a separate function and call it when needed. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-06Remove temporary highlight pointersLukas Fleischer
Add an additional check to apoint_update_panel() and todo_update_panel() and only highlight currently selected items if the corresponding panel is active. This allows us to remove all the highlight pointer juggling that we used whenever the panel selection changed. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-05Add configuration option to run the GC on exitLukas Fleischer
If "auto_gc" is enabled, the garbage collector for note files will be run on every exit. As this is an experimental feature and may cause data loss, this is disabled by default. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-21Declare foreground and background variables globalLukas Fleischer
Removes the need to pass the terminal's default background color round. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-14Do not unnecessarily refresh in config menuLukas Fleischer
We don't need to refresh windows every time an unassigned key is pressed. Add a condition to skip the refresh part if that is the case. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-07Add key binding for pipe-item commandLukas Fleischer
This removes the need of reading the whole data file and find matching entries if we want to parse appointments in external programs. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-28Avoid redundant redraws on resizeLukas Fleischer
Use a global flag to record whether the terminal was resized instead of redrawing everything each time a KEY_RESIZE is read. Add some additional checks to help_write_pad() as invalid actions may be passed now due to using signals instead of virtual key presses. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Update copyright notices in source files, documentation and "COPYING".Lukas Fleischer
* Update copyright dates (use 2004-2011 as date range everywhere). * Change copyright holder from "Frederic Culot" to "calcurse Development Team". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
