Refactor the iCal parser to reduce nesting depth. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-24Introduce starts_with() and starts_with_ci()Lukas Fleischer
Create user-defined functions to check whether a string contains a certain prefix instead of messing around with strncmp() and strncasecmp(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-23Make "Add Item" work from the calendar panelLukas Fleischer
Support the "Add item" key binding in the calendar panel and make it add a new appointment. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-23Support resize in all configuration menusLukas Fleischer
Add missing resize support in the configuration main menu and in the key bindings menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-23Add support for UTC times in iCal importsLukas Fleischer
According to the iCal standard (4.3.12 Time): UTC time, or absolute time, is identified by a LATIN CAPITAL LETTER Z suffix character (US-ASCII decimal 90), the UTC designator, appended to the time value. Parse such time values properly when importing iCal files. Fixes GitHub issue #3. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-22Use date_sec_change() for adding day deltasLukas Fleischer
Fixes tests range-002.sh and search-001.sh. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-22Use LONG_MAX for invalid dates in parse_datearg()Lukas Fleischer
We cannot use -1 here since negative values are valid dates. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-11Support weekday names as date specifiersLukas Fleischer
Allow for using shorthands like "Monday" as date specifiers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-07Update copyright rangesLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-07Add a couple of shorthands to parse_date()Lukas Fleischer
We now understand the shorthands "today", "yesterday", "tomorrow" and "now" which might come in useful sometimes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-07Handle dates past January 19th, 2038Lukas Fleischer
Try to support dates past year 2038 on systems with 64-bit time_t. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-10-17Only werase() calendar if month is changedLukas Fleischer
Optimize the monthly view by only erasing the window content when a new month is selected. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-10-10Let SIGUSR1 trigger a reloadTim Hentenaar
In an effort to better integrate the import process with external applications, it's desirable to have a mechanism by which external programs can trigger a reload of calcurse's data. This patch adds that functionality via SIGUSR1. The reload request is handled in the main loop. When the user is currently entering data, the request is delayed until the main loop is re-entered. Signed-off-by: Tim Hentenaar <tim@hentenaar.com> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-10-10Factor out item reload codeLukas Fleischer
Adds a new function io_reload_data() which can be used to reload all appointments and TODO items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-10-10Add io_load_data() wrapperLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-18Correctly parse all types of iCal durationsLukas Fleischer
This was supposed to be fixed in 6ca2535 (ical.c: Simplify and fix ical_durtime2long(), 2014-07-28) but some cases were not covered. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-18Retain comments in descriptions and config valuesLukas Fleischer
Comments should only be stripped if they start at the beginning of a line. We do not want to chop off an TODO item description or a configuration value. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-18Gracefully handle all day events in iCal importsLukas Fleischer
Do not create two events when importing an event that lasts an entire day. Reported-by: Jörn Tillmanns <tillmanns@tuxzone.org> Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-18Handle CRLF line endings in iCal filesLukas Fleischer
RFC 2445 mentions that CRLF line endings may be used in iCal files. Handle them properly when importing. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-09Fix parsing of times in parse_datetimearg()Lukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-09Extend date formats for filtersLukas Fleischer
Allow for specifying both date and time in all dates and date ranges used in filters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-08Add --filter-{start,end}-rangeLukas Fleischer
These are shorthands for --filter-start-from/--filter-start-to and --filter-end-from/--filter-end-to. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-07Add a grep modeLukas Fleischer
This allows for printing a subset of the items in the data files by using filters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06args.c: Reword error messagesLukas Fleischer
Use the same error message if option arguments have the same data type and always add the violating value. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06io.c: Error out on non-existent calendar fileLukas Fleischer
Show an error message and die if the user specified a non-existent custom calendar file. This fixes some random hangs when calcurse is used in non-interactive mode within scripts. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Use backwards-compatible out format for queriesLukas Fleischer
Print TODO items before appointments in query outputs and add an empty line between the list of TODO items and the list of appointments. This is how items were printed before the big parser refactoring. Also, add a test to ensure we do not unintentionally change that format in the future. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Do not use filters in GC or import modeLukas Fleischer
Filtering items when running garbage collection or when importing data might result in data loss, so simply ignore filters here. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Rework command line argument handlingLukas Fleischer
Add a new range query mode (--days) and refactor the command line argument parser. Note: This slightly changes the behavior of some command line parameters, since date arguments no longer use the input date format from the configuration file! Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Allow for filtering TODO itemsLukas Fleischer
The item filters now apply to both appointments and TODO items. Also, add a new type mask "todo" and the following new filter options: * --filter-priority * --filter-completed * --filter-uncompleted Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Add a query modeLukas Fleischer
Add a new parameter -Q that can be used to print all appointments inside a given query range, followed by all TODO items. The date range can be specified using the --from and --to arguments. The start date defaults to the current day, the end date defaults to the day after the start date if not specified. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Add pattern filter optionLukas Fleischer
This adds a new item filter option --filter-pattern and removes the whole -S parameter logic, while making -S an alias for --filter-pattern. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-06Add item filtersLukas Fleischer
This adds the following filter options that allow for restricting the set of items that are read from the appointments file: * --filter-type * --filter-start-from * --filter-start-to * --filter-start-after * --filter-start-before * --filter-end-from * --filter-end-to * --filter-end-after * --filter-end-before Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-08-03Make compact mode and default panel configurableLukas Fleischer
Create configuration entries for these (currently undocumented) options which were added in 4d0c095 (Add compact panels support, 2012-11-25) and in 660eef8 (Add configuration option to set a default panel, 2012-11-24). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

Suggested-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-28ical.c: Parse multiple exception rules properlyLukas Fleischer
There can be multiple EXDATE lines per event. Parse them correctly instead of making the last line overwrite the previous ones. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-28ical.c: Simplify and fix ical_durtime2long()Lukas Fleischer
Correctly parse all types of durations. Before this change, durations without an hour or minute component were not parsed properly. Reported-by: Håkan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-28io.c: Remove superfluous space from messageLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-27ui-day.c: Reorganize some free() operationsLukas Fleischer
Fixes regressions introduced in 21fc7a4 (Replace several uses of snprintf() by asprintf(), 2014-07-21). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-27Do not error out when calling xfree(NULL)Lukas Fleischer
Calling free() with NULL as parameter is perfectly safe, no need to error out here. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-27Fix find_basedir() and display_help()Lukas Fleischer
Fixes two regressions introduced in 21fc7a4 (Replace several uses of snprintf() by asprintf(), 2014-07-21). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-22config.c: Rework configuration serializationLukas Fleischer
Avoid preallocating buffers on the stack, use dynamic memory allocation instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-22Refactor new_tempfile()Lukas Fleischer
Avoid preallocating buffers on the stack, use dynamic memory allocation instead. Also, change the semantics of new_tempfile() so that it returns the full name of the temporary file and fix all call sites. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-22Replace several uses of snprintf() by asprintf()Lukas Fleischer
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>
2014-07-22Add vasprintf() and asprintf()Lukas Fleischer
The new utils.c functions vasprintf() and asprintf() are analogs to sprintf() and vsprintf(). However, instead of requiring a buffer that is large enough to hold the output data, the functions allocate a string and return a pointer to it. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-18Small code cleanupsLukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-18Use wins_set_bindings() for the configuration menuLukas Fleischer
Make use of the general key binding context switching implementation for the configuration main menu. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-07-18Make bindings always fill the whole status barLukas Fleischer
Compute padding for key bindings in the status bar such that they use all available space (without exceeding the given page size). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
