* Add hidden key handler windowLukas Fleischer2012-12-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * Replace localtime() with localtime_r()Lukas Fleischer2012-11-221-34/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Add support for copy/paste registersLukas Fleischer2012-07-071-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Revise cut/pastingLukas Fleischer2012-06-301-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use mvwaddstr() instead of mvwprintw()Baptiste Jonglez2012-05-311-15/+12
| | | | | | | | | | | | | When we only want to display a string at a specific place of the screen, there's no need to use the more complex mvwprintw(), use mvwaddstr() instead. This should be slightly more efficient, and, above all, it prevents weird things to happen if our string contains a '%', being interpreted as an unwanted format string.

* Fix incorrect i18n usage for some stringsBaptiste Jonglez2012-05-251-1/+1
| | | | | | | | | | | Some strings are initialized without wrapping them in _(); instead, _() is applied on the variable when it is used. This is incorrect, since these strings don't get added to the catalog. Fix that by applying _() only once, when the string is declared.

* | Fix default time format for multi-day appointmentsLukas Fleischer2012-05-211-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of commit 0791eaabca0fb1ef8a8675e47d701bbcde4d4a3f, we use strftime() instead of apoint_sec2str() to format start and end dates of appointments. "%H:%M" is the default strftime() format string used to simulate apoint_sec2str(). However, apoint_sec2str() additionally checks for intersection with the current day and displays "..:.." instead of the actual time if the item doesn't start (end) at the current day. Add an additional check to the new default time format and recreate the old behavior for items starting before or ending after the current day. Fixes BUG#3.

* | Switch to Linux kernel coding styleLukas Fleischer2012-05-211-783/+655
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | src/utils.c: Disable canonical mode in press_any_key()Lukas Fleischer2012-05-201-0/+10
| | | | | | | | | | | | | | | | | | Use tcsetattr() to disable canonical mode in press_any_key() before waiting for a key press.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function allows the user to choose between various alternatives, each one being associated to a given key. This will allow a great deal of factorisation, which will make it easier to handle special events (like resizing, user escape...) in an uniform manner. The cool part of the approach taken here is that it allows full i18n (i.e. the key bound to an alternative can be different depending on the language), at the expense of a somewhat less readable code on the caller side.

* | Declare several parameters/variables constantLukas Fleischer2012-05-081-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | Add "default" and "epoch" extended formats for dates. "default" is the same as "%H:%M", "epoch" prints the number of seconds since January 1, 1970. Also, change the semantics of "%(start)" to return dates in default format (same format that "%(startstr)" used to use before this patch).
