2011-07-15Refactor custom_load_conf()Lukas Fleischer
Read key and value of each configuration setting in one loop cycle to facilitate adjustments of the configuration setting format. Also, this allows us to get rid of all the redundant variable resetting. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-14Do not unnecessarily refresh in config menuLukas Fleischer
We don't need to refresh windows every time an unassigned key is pressed. Add a condition to skip the refresh part if that is the case. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-14Remove artificial delay when saving dataLukas Fleischer
This doesn't contribute to functionality or usability in any way. Keep the progress bar option but only show bars as long as the actual save operation is in progress. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-10Merge branch 'maint'Lukas Fleischer
2011-07-09Honor "TMPDIR" environment variableLukas Fleischer
Replace all hardcoded paths referring to "/tmp" with a new function that honors the "TMPDIR" environment variable as well as P_tmpdir and uses "/tmp" as a fallback. Thanks-to: Erik Saule <esaule@bmi.osu.edu> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-07Add key binding for pipe-item commandLukas Fleischer
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>
2011-07-05Add todo_pipe_item() functionLukas Fleischer
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>
2011-07-05Add day_pipe_item() functionLukas Fleischer
Serializes an appointment or an event, prompts for a shell command and executes that command in a new process, piping serialized item data to its stdin. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-05Add press_any_key() functionLukas Fleischer
Displays "Press any key to continue..." in shell terminal mode and waits for a key stroke. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-05Move endwin() down in wins_prepare_external()Lukas Fleischer
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>
2011-07-02Refactor wins_launch_external()Lukas Fleischer
* 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>
2011-07-02Add shell_exec() functionLukas Fleischer
Can be used to execute an external program in a shell. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Add child_wait() functionLukas Fleischer
Can be used to wait for the termination of a child process. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Add fork_exec() functionLukas Fleischer
Can be used to execute an external program. Provides the possibility to optionally create a pipe to the new process. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Make recur_*_write() publicLukas Fleischer
This allows one to serialize and send recurrent items to arbitrary output streams. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Refactor out todo item serializationLukas Fleischer
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>
2011-07-02utf8_width() performance improvementsLukas Fleischer
* Sort character width lookup table by character ranges. * Use binary search instead of linear search for UTF-8 character width lookups which will speed up utf8_width() (O(log n) instead of O(n)). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Avoid segfault in getstr_fixscr()Lukas Fleischer
Avoid a segfault that may occur if getstr_fixscr() changes the scroll offset to something outside the input boundaries (e.g. if a word that is only partly visible is killed via backward-kill-word). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Use constant for maximum UTF-8 character sizeLukas Fleischer
Introduce a UTF8_MAXLEN constant instead of using the literal value "6" at various places. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Refactor getstring codeLukas Fleischer
* Rename static showstring() function to getstr_print(), rename ins_char() to getstr_ins_char() and del_char() to getstr_del_char(). * Refactor out getstring data structure initialization and window scrolling routines. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-07-02Make display_todo_item() UTF-8 compatibleLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Make display_item() UTF-8 compatibleLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Make getstring() UTF-8 compatibleLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Split line editing functions into separate fileLukas Fleischer
Move getstring() related stuff into a separate file as a first step on our way to UTF-8 support for line editing helpers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Add basic UTF-8 helper functionsLukas Fleischer
Add utf8_width() and utf8_strwidth() which can be used to calculate the display width of a single character or a string, respectively. A lookup table is used to spot double width characters, as well as composing characters. There currently isn't any code to deal with ambigious characters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29src/calcurse.h: Add UTF-8 related macrosLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Enable arrow key navigation by defaultLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-29Handle resize properly in the sidebar config menuLukas Fleischer
There used to be no resize handler in custom_sidebar_config() which resulted in a messed up screen if the terminal was resized during sidebar configuration. Doing a simple wins_reset() if the terminal was resized works around this problem. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-28Do not try to display items with negative widthLukas Fleischer
Don't display anything rather than segfault if the appointment panel becomes too small (e.g. during a terminal resize). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-28Always work with new window dimensions on resizeLukas Fleischer
This one came up after improving resizing behaviour in commit fec37db06bbbdff79bc9816046a76e0b29e173b4. We used to use outdated width and height values at various places without noticing it due to the resize algorithm being called several times on every resize. This patch ensures we retrieve the new window dimensions *before* doing any layout calculations. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-28Avoid redundant redraws on resizeLukas Fleischer
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>
2011-06-20src/llist.c: Use stable insertion algorithmLukas Fleischer
Ensure the relative order of elements with equal keys is maintained when inserting into a sorted list. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-09Fix whitespace issuesLukas Fleischer
Strip trailing whitespaces in all source files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-06-07src/utils.c: Make bell() staticLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-05-17Add missing llist header files to "_SOURCES".Lukas Fleischer
We forgot to add those to the "_SOURCES" variable in commit 0eb1da8dd7fa3ae9d95e12df6058fb41a5ec1c11 and d668963e2056027526374098efe2869a0d389b92. Spotted by `make distcheck`. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Update copyright notices in source files, documentation and "COPYING".Lukas Fleischer
* 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>
2011-04-22Ignore daemon lock file if the daemon process died.Lukas Fleischer
Do this in a fashion similar to what was done in commit 6ff95238766656c5ea9d5c65c35d3aef93499f60. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Return -1 in io_file_is_empty() if file cannot be accessed.Lukas Fleischer
Ensure files don't appear as empty if fopen() fails (e.g. on temporary EACCES failures). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Use "event" structure when iterating over events in app_arg().Lukas Fleischer
Regression introduced in commit 5b174ba5d46c256f41c1cfb952d46f49a088db8a. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Add comments to linked list functions.Lukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22llist.c: Nullify pointers after free()'ing.Lukas Fleischer
* Set all data members to "NULL" in llist_free_inner() after freeing them. Altough we normally shouldn't continue working with a list that already went through llist_free_inner(), this will protect against dangling pointer bugs in case anyone will ever come up with the idea of doing so. * Set list head to "NULL" in llist_free(), basically to put the list into an initialized state. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Use generic lists for recurring item exceptions.Lukas Fleischer
Rename "days" structure to "excp" which seems to be a better name here. Use generic linked lists of excp structures instead of using the "days" structure which again contains a linked list implementation. Do some cleanups and invocation fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Remove "next" member from "recur_apoint" structure.Lukas Fleischer
Field seems to be unused. Verify using following spatch: ---- @@ struct recur_apoint *rapt; @@ * rapt->next ---- Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for recurring apointments and events.Lukas Fleischer
Use them instead of "recur_apoint_list" and "next" pointers in "recur_event" type variables. Includes some code simplifications and cleanups. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Add recur_apoint_inday() and recur_event_inday().Lukas Fleischer
To be used with llist_fn_match_t callbacks later. I feel a bit ill adding those functions. This definitely is a hack. Ultimately, there should be some generic recur_item_inday() function that accepts both recurring apointments and events (or some wrapper structure) instead of parameter galeere. This is not the right place to fix that tho. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for generic day items.Lukas Fleischer
Use the new generic list implementation instead of "next" pointers in day_item type variables. Includes some cleanups and fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for todo items.Lukas Fleischer
Use the new generic list implementation instead of "next" pointers in todo items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for events.Lukas Fleischer
Use the new generic list implementation instead of those insane "next" pointers in events. Includes some cleanups. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Remove "next" member from "apoint" structure.Lukas Fleischer
Field seems to be unused. Verify using following spatch: ---- @@ struct apoint *apt; @@ * apt->next ---- Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for appointments.Lukas Fleischer
Use the new generic list implementation instead of "apoint_list" everywhere. Simplify stuff and drop unused variables as well. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
