* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-221-2/+3
| | | | | | | | 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>
* Small code cleanupsLukas Fleischer2014-07-181-2/+1

* Use wins_set_bindings() for the configuration menuLukas Fleischer2014-07-181-34/+25
| | | | | | | Make use of the general key binding context switching implementation for the configuration main menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Initialize prompt buffers in the configuration menusLukas Fleischer2014-07-181-1/+4
| | | | | | | | malloc() does not make sure that the buffer is initialized to contain all zeros. Initialize the buffer with the empty string. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rework key binding context switchingLukas Fleischer2014-07-171-50/+20
| | | | | | | Store key binding contexts using another data structure to optimize space usage and execution time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Reintroduce key bindings in configuration menusLukas Fleischer2014-07-171-2/+14
| | | | | | | | | | The key bindings display in the status bar was removed from the general options menu in bd182fb (Use generic list box for general options, 2014-05-13) and from the notification options menu in 5eea05a (Use generic list box for notification options, 2014-05-13). Display the new key bindings to use for navigation. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Resize panels properlyLukas Fleischer2014-05-191-1/+1
| | | | | | | Rewrite the panel resize code and remove the code that reinitializes the caption and the selected item when the window is resized. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add support for caption rows in list boxesLukas Fleischer2014-05-181-2/+7
| | | | | | | This adds support for rows that cannot be selected. Such rows can be used for section headings and the like. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add support for drawing highlighted decorationLukas Fleischer2014-05-181-3/+3
| | | | | | | This allows for drawing selected scroll windows and list boxes with a highlighted border. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* custom.c: Simplify codeLukas Fleischer2014-05-181-10/+1

* Remove numbers and whitespace from option menusLukas Fleischer2014-05-181-20/+20
| | | | | | | These are no longer needed since items are no longer accessed via numeric keys. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Reduce flicker when resizing in option menusLukas Fleischer2014-05-181-1/+1
| | | | | | | Do not update the main windows when resizing the terminal in the general options menu or in the notification options menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use generic list box for general optionsLukas Fleischer2014-05-181-156/+187
| | | | | | | | | This changes the general options menu to use the new generic list box implementation. The only user-visible change is that items are now accessed via the arrow and edit key bindings instead of digits. This also allows for easily adding more than 10 options to the menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rework scroll window implementationLukas Fleischer2014-05-181-41/+19
| | | | | | | | | | This complete rewrite of the scroll window implementation decouples scroll windows from every other window abstraction layer we use. Note that this leads to some code duplication. The long-term purpose of this rewrite, however, is to eventually make every panel use scroll windows. This makes for a huge cleanup of the UI code. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Drop legacy online help systemLukas Fleischer2013-07-171-39/+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>
* Use a macro to determine the size of arraysLukas Fleischer2013-05-041-4/+4
| | | | | | | | 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 Fleischer2013-04-141-908/+961
| | | | | | | | | | | 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>
* Fix braces in if-else statementsLukas Fleischer2013-02-171-7/+10
| | | | | | | | | | From the Linux kernel coding guidelines: Do not unnecessarily use braces where a single statement will do. [...] This does not apply if one branch of a conditional statement is a single statement. Use braces in both branches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-141-2/+2
| | | | | | | | | 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>

| * Update copyright rangesLukas Fleischer2013-02-041-1/+1
| | | | | | | | | | | | | | Add 2013 to the copyright range for all source and documentation files. Reported-by: Frederic Culot <frederic@culot.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * Close key binding window when reassigning the same keyMichael Smith2013-02-041-0/+6
| | | | | | | | | | | | | | | | | | | | This allows for canceling a key reassignment. We cannot use a static key here since every key could potentially be used in a binding. Instead, just cancel if we are trying to reassign a key that has already been used for that action before.

* | custom.c: Fix sidebar configuration help textLukas Fleischer2013-01-301-4/+3
|/ | | | | | | * Use a format string instead of the TOSTRING() macro. * Remove "xgettext:no-c-format" hack and use "%%" instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add hidden key handler windowLukas Fleischer2012-12-161-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add support for copy/paste registersLukas Fleischer2012-07-071-4/+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.

* src/custom.c: Mark sidebar help string "no-c-format"Lukas Fleischer2012-06-011-0/+1
| | | | | | | | This one was incorrectly detected as C format string due to the literal percent sign ("%") contained in the message. Add a comment that explicitly marks it as non-format string to avoid translation issues. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Give a meaning to DATE_FORMATSBaptiste Jonglez2012-05-311-1/+1
| | | | | | | | | | | It's a bit weird to consider DATE_FORMATS as part of the date input format enum, all the more so as it does not even represent the number of available formats (since those are numbered from 1). Turn DATE_FORMATS into the number of available date input formats. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/custom.c: Use status_ask_simplechoice()Baptiste Jonglez2012-05-311-11/+14
| | | | | | | | | | | | | This eases up i18n somewhat, since the various date format available are used on other places as well, and thus need to be translated only once. Note that this commit incidentally fixes a small bug introduced by 38912b36: the user was able to set the date input format to a number between 1 and 5, while there are only 4 such formats available.

* Use mvwaddstr() instead of mvwprintw()Baptiste Jonglez2012-05-311-43/+43
| | | | | | | | | | | | | 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. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* 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. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not localize configuration optionsLukas Fleischer2012-05-231-10/+10
| | | | | | | | | The configuration options shown in the configuration menu are meant to reflect the keys used in the configuration file. The descriptions displayed alongside each option should be sufficient for non-English speakers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-797/+723
| | | | | | | | | | | | | | 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>
* Fix data type of "general.firstdayofweek"Lukas Fleischer2012-05-171-6/+7
| | | | | | | | | | | This option wasn't converted to a proper data type when it was renamed from "week_begins_on_monday" to "general.firstdayofweek". Convert the boolean option into an enumeration type that can take the values "monday" and "sunday". Also, update the documentation, add a conversion rule to the upgrade script and convert the configuration file used in the test suite. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Update configuration dialogsLukas Fleischer2012-05-171-16/+16
| | | | | | | Rename the configuration options shown in the configuration dialogs to match the new naming scheme used in the configuration file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Declare several parameters/variables constantLukas Fleischer2012-05-081-7/+7
| | | | | | | | | | | | 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>
* Mark localized string literals constantLukas Fleischer2012-04-051-11/+11
| | | | | | | Translated strings returned by gettext() are statically allocated and shouldn't be modified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix semantics of "general."{systemdialogs,progressbar}Lukas Fleischer2012-03-291-8/+8
| | | | | | | | | 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 Fleischer2012-03-261-1/+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 Fleischer2012-03-121-7/+5
| | | | | | | | 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>
* Avoid redundant window resets in config menuLukas Fleischer2012-03-121-1/+4
| | | | | | | There's no need to reset windows unless the layout was changed. Move wins_reset() to a separate branch to reflect this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid redundant virtual screen updatesLukas Fleischer2012-03-121-1/+0
| | | | | | | | | | Remove some redundant wnoutrefresh() invocations. There's no need to copy a window to the virtual screen unless doupdate() is invoked immediately afterwards. This reduces flicker when browsing in the calendar panel. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Break out configuration main menuLukas Fleischer2012-03-021-0/+55
| | | | | | | 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>
* Revamp key bindings displayLukas Fleischer2012-03-021-15/+23
| | | | | | | | | | | | | 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>
* Extract config file handlers into a separate fileLukas Fleischer2011-12-091-402/+0
| | | | | | | | 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>
* Use a global configuration variableLukas Fleischer2011-11-141-41/+41
| | | | | | | 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>
* 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>
* Make use of the NULL macroLukas Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | Use this constant everywhere when referring to a null pointer instead of casting 0 to various types of pointers. Created using following semantic patch: @@ type type; @@ - (type *)0 + NULL Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not cast unused return values to voidLukas Fleischer2011-11-021-17/+16
| | | | | | | | | | | | | | | | | | | | 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 Fleischer2011-11-021-5/+5
| | | | | | | | | | | | | | | | 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.
