* Avoid core dump if window is too smallLukas Fleischer2012-11-251-0/+3
| | | | | | | Avoid setting the maximum number of items to a negative number (which eventually results in a core dump). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor todo_chg_priority()Lukas Fleischer2012-11-181-18/+7
| | | | | | | Instead of passing a key, pass the number of steps to increase the priority by. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use integers rather than floats everywhereLukas Fleischer2012-07-101-3/+2
| | | | | | | | | | | We don't need floating point precision if results are casted back to integer. Instead, rearrange operations and do the integer division after the multiplication. Version numbers are terminating decimals anyway and can be stored using two integers without losing any information. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Revise todo_delete_note_bynum()Lukas Fleischer2012-07-041-7/+1
| | | | | | | Pass an item instead of passing a list item index (analogous to commit 02c90ba53a658686bad5cb5f88c555d9eef06399). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Make *_free() publicLukas Fleischer2012-06-301-1/+1
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add an item parameter to various todo_*() functionsLukas Fleischer2012-06-301-11/+4
| | | | | | | | 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>
* Revise *_delete{,_bynum}()Lukas Fleischer2012-06-301-4/+3
| | | | | | | | Always pass an item instead of passing a date and a index. This makes use of the NULL callback that was added with one of the previous patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Move interaction functions to a separate fileLukas Fleischer2012-06-301-105/+3
| | | | | | | | | | | | | | | This is a first step to clean up several compilation units and separate the front end from back-end operations. All functions that require user interaction are moved to a new compilation unit "interaction.c". Also, following things are adjusted to the new layout: * Make day_item_get_*() and a few other functions public, so that it can be accessed from the new compilation unit. * Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing static variables. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-232/+189
| | | | | | | | | | | | | | 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>
* Allow passing additional parameters to shell_exec()Lukas Fleischer2012-05-161-1/+2
| | | | | | | | This allows for specifying multiple command line parameters to be passed on to the command in a way similar to fork_exec(). This is useful if we want to wrap editor or pager invocations in a shell. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Factorize boolean user prompting.Baptiste Jonglez2012-05-141-11/+2
| | | | | | | | | | | 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>
* Use status_ask_choice() where applicableBaptiste Jonglez2012-05-141-14/+10
| | | | | | | These cases make obvious candidates for factorisation. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> 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>
* Mark several functions staticLukas Fleischer2012-04-201-1/+1
| | | | | | | These are not needed outside of the corresponding compilation units. Spotted with "-Wmissing-prototypes". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Miscellaneous small code cleanupsLukas Fleischer2012-04-061-2/+1
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Mark localized string literals constantLukas Fleischer2012-04-051-6/+6
| | | | | | | Translated strings returned by gettext() are statically allocated and shouldn't be modified. 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>
* src/todo.c: Remove several unneeded variablesLukas Fleischer2011-12-091-19/+14
| | | | Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a global configuration variableLukas Fleischer2011-11-141-2/+2
| | | | | | | 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 Fleischer2011-11-021-5/+5
| | | | | | | | | | | | | | 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 Fleischer2011-11-021-1/+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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add count parameter to *_{in,de}crease()Lukas Fleischer2011-10-061-8/+8
| | | | | | | | | 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>
* Remove temporary highlight pointersLukas Fleischer2011-10-061-1/+1
| | | | | | | | | 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>
* Do not unlink() note files on note removalLukas Fleischer2011-10-051-6/+6
| | | | | | | | | | Now that we use hash-based note file names, note files should never be unlinked as a note file might be shared. Also, remove the ERASE_FORCE_KEEP_NOTE flag that no longer makes any sense. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Accept variable length note namesLukas Fleischer2011-10-051-2/+2
| | | | | | | | Read up to the first blank in note_read() instead of assuming a fixed-width note file name. Accept everything up to 40 characters (which is the length of a SHA1 hash in hexadecimal representation). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor out note functionsLukas Fleischer2011-07-211-25/+4
| | | | | | | | | | * Add new note_edit() and note_view() helper functions. Use these instead of copy-pasted code in *_note_edit(). * Move all note-related functions (note_edit(), note_view(), note_erase()) to a new source file "note.c". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add todo_pipe_item() functionLukas Fleischer2011-07-051-0/+29
| | | | | | | Pipe a serialized todo item to an external process, similar to what day_pipe_item() does (cf. c3f532d814e555abf67efb136491956428f19965). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor out todo item serializationLukas Fleischer2011-07-021-0/+9
| | | | | | | | Add a todo_write() function that allows one to serialize todo items and write serialized data to an output stream in a fashion similar to apoint_write() and event_write(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use constant for maximum UTF-8 character sizeLukas Fleischer2011-07-021-1/+1
| | | | | | | Introduce a UTF8_MAXLEN constant instead of using the literal value "6" at various places. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Make display_todo_item() UTF-8 compatibleLukas Fleischer2011-07-021-5/+14

* Update copyright notices in source files, documentation and "COPYING".Lukas Fleischer2011-04-221-1/+1
| | | | | | | | | * 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>
* Return -1 in io_file_is_empty() if file cannot be accessed.Lukas Fleischer2011-04-221-1/+1
| | | | | | | Ensure files don't appear as empty if fopen() fails (e.g. on temporary EACCES failures). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use generic lists for todo items.Lukas Fleischer2011-04-191-105/+72
| | | | | | | Use the new generic list implementation instead of "next" pointers in todo items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Drop empty notes after editing.Lukas Fleischer2011-04-121-0/+3
| | | | | | | | | Keeping empty notes doesn't make sense here. Also, there doesn't seem to be a simple way to erase notes yet. This will make calcurse delete any notes that are empty (meaning that they are either 0-byte files or contain nothing but a newline character) when returning from the editor.
