* Check for the year span 1902-2037Lars Henriksen2017-11-231-6/+8
| | | | | | | | | | | | | Reintroduce year check for systems with a 32-bit time_t type. Remove the lower limit (1902) for systems with a 64-bit time_t. This limits movements in the calendar (for 32-bit systems) and in no way ensures constistency of data. Commit a12833e (Handle dates past January 19th, 2038, 2015-01-19) removed the upper limit (2037) on dates but left the lower limit (1902). It did not ensure the support of the target system.

* Parse time before date in parse_datetime()Lukas Fleischer2017-10-271-2/+2
| | | | | | | | | Make sure that in cases when the date and time formats conflict, such as is the case with "0030", the input is interpreted as a time value, not a date. Suggested-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make parsing of date-time more strictLukas Fleischer2017-10-261-15/+20
| | | | | | | | | | | In parse_datetime() it was possible to enter any number of dates and times in any order. Allow just date or time or date followed by time. Time must be looked for before date because of conflicting time and date formats. Suggested-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add parse_date_interactive()Lukas Fleischer2017-10-261-0/+7
| | | | | | | | | Add a wrapper around parse_date() which picks the current input date format as well as the currently selected day and passes both values to parse_date(), alongside with the parameters passed to parse_date_interactive() itself. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Remove phase of moon featureLars Henriksen2017-09-081-2/+0
| | | | | | | | | | The computation never really worked before and it seems like the feature is not very helpful, sometimes even confusing (see GitHub issue #21). The macro ISLEAP is moved to calcurse.h. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Replace remaining uses of wgetch() by keys_wgetch()Lukas Fleischer2017-09-031-1/+1
| | | | Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add a function to wait for any key pressLukas Fleischer2017-09-031-3/+3
| | | | | | | Introduce a new function keys_wait_for_any_key() and use it instead of wgetch() whenever the return value is discarded. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix empty warning box when key is already in useLars Henriksen2017-08-121-0/+2
| | | | | | | | | | | | When adding a key already in use for another action, a warning box is displayed. The text length is limited by the window width through the use of strncpy(). If the limit is exceeded, the string will have no null termination, resulting in unpredictable behaviour. A similar problem in fatalbox() is fixed as well.

* Replace parse_datetime() constants by named flagsLukas Fleischer2016-10-101-2/+2
| | | | | | | Remove the magic constants used in the return value of parse_datetime() and use named flags instead. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Support dates when specifying start/end timesLukas Fleischer2016-10-091-2/+6
| | | | | | | | | | Add support for combined date/time or date-only strings when specifying the start or end time of a new item. This is a follow-up to 1f39b5c (Add support for moving items to another day, 2016-09-30). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Factor out parse_datetime()Lukas Fleischer2016-10-091-0/+39
| | | | | | | | Create a new function that takes a time stamp and updates the date or time components of that time stamp according to a given date/time string. Use that function for updating the start time of an item. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Stop all threads before leaving curses modeLukas Fleischer2016-09-131-2/+4
| | | | | | | This prevents from notification bar artifacts being drawn after leaving interactive mode. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Do not assume that days always have 86400 secondsLukas Fleischer2016-03-271-0/+24
| | | | | | | | Make that date membership is computed correctly, even if a day has less than 86400 seconds (e.g. after changing clocks). Reported-by: Hakan Jerning <jerning@home.se> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Support durations in recurrence ending datesLukas Fleischer2016-02-261-0/+91
| | | | | | | When spending the end date of recurring items, allow date duration specifiers such as "+5d" or "+3w2d". Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Allow decimals in durationsLukas Fleischer2016-02-101-9/+16
| | | | | | Parse durations containing decimal numbers (such as "1.5h") gracefully. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix %(hash) formatting of eventsLukas Fleischer2016-02-051-2/+2
| | | | | | Actually print the hash instead of raw object data. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Refactor grep modeLukas Fleischer2016-02-051-0/+1
| | | | | | | | | Split io_save_{apts,todo}() into functions that write raw data to a file and functions that write formatted items to stdout such that one can easily extend the grep mode for format string support in a follow-up commit. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Add command line option to suppress dialogsLukas Fleischer2016-01-131-0/+5
| | | | | | | Implement a -q/--quiet command line option to disable system dialogs temporarily. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add an option to filter by object hashLukas Fleischer2016-01-131-0/+12
| | | | | | | | | Implement a new --filter-hash option to filter by object identifiers. Each object having an identifier that has the specified pattern as a prefix is matched. Patterns starting with an exclamation mark (!) are interpreted as negative patterns. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add long format specifiers "raw" and "hash"Lukas Fleischer2016-01-131-5/+55
| | | | | | | Add new format specifiers to print the raw item representation or an object's hash value. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Reimplement asprintf() using dynamic stringsLukas Fleischer2016-01-131-26/+4
| | | | | | Use the new string implementation to simplify asprintf(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Split out code for drawing week numbersLukas Fleischer2015-04-101-2/+9
| | | | | | | This allows for easily adding week numbers to other panel modes, such as the monthly view. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Simplify code in status_ask_choice()Lukas Fleischer2015-02-241-7/+5

* Use time_t instead of long in several placesLukas Fleischer2015-02-241-16/+10
| | | | | | | Start converting some variables and return values to store times from long to time_t. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Introduce starts_with() and starts_with_ci()Lukas Fleischer2015-02-241-0/+12
| | | | | | | | 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>
* Add support for UTC times in iCal importsLukas Fleischer2015-02-231-0/+25
| | | | | | | | | | | | | | 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>
* Use date_sec_change() for adding day deltasLukas Fleischer2015-02-221-6/+5
| | | | | | Fixes tests range-002.sh and search-001.sh. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Support weekday names as date specifiersLukas Fleischer2015-02-111-5/+51

* Add a couple of shorthands to parse_date()Lukas Fleischer2015-02-071-0/+25
| | | | | | | We now understand the shorthands "today", "yesterday", "tomorrow" and "now" which might come in useful sometimes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Handle dates past January 19th, 2038Lukas Fleischer2015-02-071-4/+2
| | | | | | Try to support dates past year 2038 on systems with 64-bit time_t. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Refactor new_tempfile()Lukas Fleischer2014-07-221-10/+7
| | | | | | | | 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>
* Replace several uses of snprintf() by asprintf()Lukas Fleischer2014-07-221-9/+10
| | | | | | | | 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>
* Add vasprintf() and asprintf()Lukas Fleischer2014-07-221-0/+38
| | | | | | | | | 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>
* Add default cases to some switch statementsLukas Fleischer2014-05-181-0/+2
| | | | | | This squelches several compiler warnings. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Store appointments for the current day in a vectorLukas Fleischer2014-05-181-1/+1
| | | | | | This allows for more efficient access to items at specific positions. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rework scroll window implementationLukas Fleischer2014-05-181-1/+1
| | | | | | | | | | 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.

* Allow extended formats for durationsLukas Fleischer2013-07-171-1/+5
| | | | | | | Use print_datediff() to print durations. This allows for using something like "%(duration:%EH:%M)". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* print_datediff(): Actually print a date differenceLukas Fleischer2013-07-171-5/+3
| | | | | | | | | Instead of passing a date and printing the date difference between that date and the current date, pass an actual date difference. This allows for using the function in other places, such as for printing item durations. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add %(remaining) style formattingWilliam Pettersson2013-07-171-0/+83
| | | | | | | | Adds %(remaining) style formatting, with parameter substitution for %d, %H, %M, %S with E and - variables. Signed-off-by: William Pettersson <william.pettersson@gmail.com> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-935/+954
| | | | | | | | | | | 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>
* parse_{date,time}(): Split out date/time validationLukas Fleischer2013-02-271-3/+23
| | | | | | | | Split date/time validation into separate functions check_date() and check_time(). These will be used to validate date/time information when reading items from the appointments file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* date_sec2date_str(): Add missing semicolonLukas Fleischer2013-02-191-1/+1
| | | | | | Regression introduced in a363cb9b9111aed22d105adb0e7a8e9caab9bbe3. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix braces in if-else statementsLukas Fleischer2013-02-171-20/+31
| | | | | | | | | | 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>
* parse_duration(): Bail out early in final stateLukas Fleischer2013-02-141-6/+4
| | | | | | | Bail out early if we are reading a character while being in a final state. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* calendar.c: Rename to "ui-calendar.c"Lukas Fleischer2013-02-141-1/+1
| | | | | | | | | 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>
