* Allow undefined actions in keys configuration fileLars Henriksen2021-04-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the keys file there are three possibilities for each action: 1. One or several keys are assigned to it 2. It is marked as UNDEFINED (new) 3. It is missing from the file On load of the keys file, calcurse respectively 1. Assigns the key(s) 2. Assigns "UNDEFINED" (new) 3. Assigns a default key if possible If default keys were assigned, the user is informed of the number of actions affected, and the keys file is updated. After load each action must either have keys assigned or be undefined. If not, calcurse exits with a failure. If there are syntax/semantic errors in the file, calcurse rejects the file and exits. When an interactive user leaves the keys configuration menu, a warning is issued if any action is UNDEFINED. The keys file is always updated. Addresses GitHub issue #298. Additionally: Description of concepts and data structures used for keyboard keys and virtual keys (actions) as well as name changes and comments to improve readability.

* Fix help for nine actionsLars Henriksen2017-11-151-4/+18
| | | | | | | | | | | | Seven actions were absent from display_help(). This meant that commands like ':help ^P' did not work. They now refer to general.txt, but are not all described there. For two actions, generic-copy/paste, the file name was misspelled. This solves Github issue #44. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Fix find_basedir() and display_help()Lukas Fleischer2014-07-271-4/+2
| | | | | | | Fixes two regressions introduced in 21fc7a4 (Replace several uses of snprintf() by asprintf(), 2014-07-21). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-221-18/+29
| | | | | | | | 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>
* Refactor wins_launch_external()Lukas Fleischer2014-07-161-1/+2
| | | | | | | | 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>
* Display translated help pagesLukas Fleischer2013-08-271-3/+56
| | | | | | | Use an algorithm similar to gettext's locale resolution to find an appropriate translation to display. Fall back to the English version. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split online help code into a separate functionLukas Fleischer2013-07-181-0/+144
| | | | | | | Reintroduce help.c and move the online help code into a new function display_help(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Drop legacy online help systemLukas Fleischer2013-07-171-804/+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>
* Fix a couple of translatable stringsLukas Fleischer2013-05-141-5/+5
| | | | | | | | * Remove space before punctuation. * Use "TODO" instead of "ToDo". * Strip some formats to make sure lines are <=80 characters wide. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-707/+710
| | | | | | | | | | | 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>

* Add hidden key handler windowLukas Fleischer2012-12-161-1/+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>
* Merge cut/deleteLukas Fleischer2012-07-071-18/+11
| | | | | | | 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>
* Add support for copy/paste registersLukas Fleischer2012-07-071-1/+1
| | | | | | | | | | | | | | | | | 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>
* Add a key binding for generic-copyLukas Fleischer2012-07-061-12/+16
| | | | | | This finally adds full copy-paste support. Implements FR#15. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/help.c: Add missing _()Lukas Fleischer2012-06-181-1/+1
| | | | | | | Add a missing gettext wrapper. This string should be translated. Reported-by: rafael ff1 <rafael.f.f1@gmail.com> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add key bindings to go to the previous/next month/yearLukas Fleischer2012-06-131-0/+16
| | | | | | | | | | 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 Fleischer2012-06-131-4/+4
| | | | | | | | | | * 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>
* Use mvwaddstr() instead of mvwprintw()Baptiste Jonglez2012-05-311-2/+2
| | | | | | | | | | | | | 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.

* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-592/+580
| | | | | | | | | | | | | | 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>
* Declare several parameters/variables constantLukas Fleischer2012-05-081-1/+1
| | | | | | | | | | | | 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>
* Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer2012-03-291-2/+2
| | | | | | | | | 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>
* Update copyright rangesLukas Fleischer2012-03-261-2/+2

* Do not strncpy() strings returned by gettext()Lukas Fleischer2012-03-121-1/+1
| | | | | | | | 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>
* 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 Fleischer2011-11-021-27/+27
| | | | | | | | | | | | | | | | | | | | 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 Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | | 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.

* Add count buffer to keys_getch()Lukas Fleischer2011-10-061-1/+1
| | | | | | | | 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>
* Add key binding for pipe-item commandLukas Fleischer2011-07-071-0/+13
| | | | | | | 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>
* Avoid redundant redraws on resizeLukas Fleischer2011-06-281-29/+34
| | | | | | | | | | 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>
