* Ignore signals during command executionLukas Fleischer2012-11-281-0/+4
| | | | | | | | | | | | 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.

* Release screen mutex if thread diesLukas Fleischer2012-11-231-10/+32
| | | | | | | | | | | | | | | | | 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 Fleischer2012-11-231-0/+28
| | | | | | | | | | | | 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>
* Add key bindings to go to the previous/next month/yearLukas Fleischer2012-06-131-3/+10
| | | | | | | | | | 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>
* Rename displacement enumeration elementsLukas Fleischer2012-06-131-8/+8
| | | | | | | | | | * 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>
* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-426/+359
| | | | | | | | | | | | | | 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>
* src/wins.c: Run editor and pager in a shellLukas Fleischer2012-05-161-1/+1
| | | | | | | | | This allows for specifying an editor or a pager with additional command line parameters, such as "vim -e". Instead of interpreting "vim -e" as an executable file, we leave it to the shell to tokenize and parse the editor command now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Declare several parameters/variables constantLukas Fleischer2012-05-081-2/+2
| | | | | | | | | | | | Add the "const" keyword to parameters and variables that are never modified. Most of these were spotted by "-Wwrite-strings". We cast the second parameter to execvp() explicitly as it expects a "char *const[]" where it should expect a "const char *const[]" (according to the documentation, this is due to compatibility reasons). This should be changed once we come up with a better solution. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Various code cleanupBaptiste Jonglez2012-05-021-11/+3
| | | | | | | | Remove obsolete bits of code that weren't thrown away by b5c1981; simplify some others areas of the code. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use percentage-based width for the sidebarLukas Fleischer2012-04-121-23/+14
| | | | | | | | | | Use percentage-based widths internally. This slightly impairs (user) feedback but brings the sidebar configuration menu closer to the actual configuration format (the user now configures percentage-based widths, not absolute width values). As a bonus, the sidebar is now resized automatically on each window resize (based on the percentage values). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Update copyright rangesLukas Fleischer2012-03-261-1/+1
| | | | | | Add 2012 to the copyright range for all source and documentation files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not strncpy() strings returned by gettext()Lukas Fleischer2012-03-121-9/+4
| | | | | | | | Translated strings returned by gettext() are statically allocated. There's no need to copy them to a buffer, we can use the pointers returned by gettext() instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Revamp key bindings displayLukas Fleischer2012-03-021-28/+46
| | | | | | | | | | | | | Refactor the logic inside keys_display_bindings_bar() and remove the need to place the "show next page" key binding at the right positions. This used to be a pain to maintain, since we always had to move key bindings around when introducing a new key. Fix this by passing the actual key bindings in an array and using a separate parameter for the "show next page" key binding (which is automatically inserted at the right places from now on). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove parentheses from return statementsLukas Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | No reason to use "return (x);" here. Refer to the GNU coding guidelines for details. Created using following semantic patch: @@ expression expr; @@ - return (expr); + return expr; Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not cast unused return values to voidLukas Fleischer2011-11-021-4/+4
| | | | | | | | | | | | | | | | | | | | A small style fix that removes all remaining "(void)" casts. Using these isn't encouraged in GNU coding guidelines and doesn't serve a certain purpose, except for satisfying a few static code analysis tools. We already nuked some of these in previous patches, but this semantic patch should fix what's left: @@ identifier func; @@ - (void)func ( + func ( ...); Long lines were re-formatted manually. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid use of printf()/fprintf()Lukas Fleischer2011-11-021-3/+3
| | | | | | | | | | | | | | | | Use one of the following functions where appropriate: * puts() (whenever we print hard coded strings to stdout) * fputs() (whenever we print hard coded strings to a stream) * putchar() (whenever we print a single character to stdout) * fputc() (whenever we print a single character to a stream) * strncpy() (whenever we copy hard coded strings to a buffer) This removes the overhead introduced by the format string parser and reduces the number of false positive C-format strings spotted by xgettext(1)'s heuristics. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid unnecessary window updatesLukas Fleischer2011-10-061-30/+34
| | | | | | | | 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>
* Add key binding for pipe-item commandLukas Fleischer2011-07-071-7/+9
| | | | | | | 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>
* Move endwin() down in wins_prepare_external()Lukas Fleischer2011-07-051-1/+1
| | | | | | | | Invoke endwin() *after* calling any other curses functions, such as refresh(). Calling refresh() after endwin() might restore curses mode which is a bad thing for a terminal mode initialization routine. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor wins_launch_external()Lukas Fleischer2011-07-021-19/+24
| | | | | | | | | * Do window preparation and restoring in separate functions wins_prepare_external() and wins_unprepare_external(). * Use fork_exec() and child_wait() instead of system(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
