2016-10-10Replace parse_datetime() constants by named flagsLukas Fleischer
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>
2016-10-09Support dates when specifying start/end timesLukas Fleischer
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>
2016-10-09Factor out parse_datetime()Lukas Fleischer
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>
2016-09-13Stop all threads before leaving curses modeLukas Fleischer
This prevents from notification bar artifacts being drawn after leaving interactive mode. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-03-27Do not assume that days always have 86400 secondsLukas Fleischer
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>
2016-02-26Support durations in recurrence ending datesLukas Fleischer
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>
2016-02-10Allow decimals in durationsLukas Fleischer
Parse durations containing decimal numbers (such as "1.5h") gracefully. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-02-05Fix %(hash) formatting of eventsLukas Fleischer
Actually print the hash instead of raw object data. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-02-05Refactor grep modeLukas Fleischer
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>

2016-01-13Add command line option to suppress dialogsLukas Fleischer
Implement a -q/--quiet command line option to disable system dialogs temporarily. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-13Add an option to filter by object hashLukas Fleischer
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>
2016-01-13Add long format specifiers "raw" and "hash"Lukas Fleischer
Add new format specifiers to print the raw item representation or an object's hash value. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2016-01-13Reimplement asprintf() using dynamic stringsLukas Fleischer
Use the new string implementation to simplify asprintf(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
2015-04-10Split out code for drawing week numbersLukas Fleischer
This allows for easily adding week numbers to other panel modes, such as the monthly view. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-24Simplify code in status_ask_choice()Lukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2015-02-24Use time_t instead of long in several placesLukas Fleischer
Start converting some variables and return values to store times from long to time_t. 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>
2015-02-23Add 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>
2015-02-11Support 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>
2014-07-22Refactor 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>
2014-05-18Add default cases to some switch statementsLukas Fleischer
This squelches several compiler warnings. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-05-18Store appointments for the current day in a vectorLukas Fleischer
This allows for more efficient access to items at specific positions. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2014-05-18Rework scroll window implementationLukas Fleischer
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>
2013-07-17Add a short format specifier for "%(remaining)"Lukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-07-17Allow extended formats for durationsLukas Fleischer
Use print_datediff() to print durations. This allows for using something like "%(duration:%EH:%M)". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-07-17print_datediff(): Actually print a date differenceLukas Fleischer
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>
2013-07-17Add %(remaining) style formattingWilliam Pettersson
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>
2013-04-14Use tabs instead of spaces for indentationLukas Fleischer
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>
2013-02-27parse_{date,time}(): Split out date/time validationLukas Fleischer
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>
2013-02-19date_sec2date_str(): Add missing semicolonLukas Fleischer
Regression introduced in a363cb9b9111aed22d105adb0e7a8e9caab9bbe3. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-02-17Fix braces in if-else statementsLukas Fleischer
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>
2013-02-14parse_duration(): Bail out early in final stateLukas Fleischer
Bail out early if we are reading a character while being in a final state. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2013-02-14calendar.c: Rename to "ui-calendar.c"Lukas Fleischer
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>
2013-02-14Rename appointment/event-related UI functionsLukas Fleischer
* Rename "interaction.c" to "ui-day.c" since it no longer contains todo-related UI functions. * Rename appointment/event-related UI functions to ui_day_*(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2013-02-04Update copyright rangesLukas Fleischer
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>
2013-01-30Use strncasecmp() for case-insensitive comparisonLukas Fleischer
Instead of converting everything to upper case and then using strncmp(), use strncasecmp() which does case-insensitive comparison out of the box. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2012-12-16Add hidden key handler windowLukas Fleischer
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>

2012-11-22Replace localtime() with localtime_r()Lukas Fleischer
Since the result of localtime() is stored in a statically allocated structure, data was overwritten when a context switch occurred during (or shortly after) the execution of localtime(), potentially resulting in critical data corruption. BUG#7 and BUG#8 are likely related. This patch converts all usages of localtime() with localtime_r(), which is thread-safe. Reported-by: Baptiste Jonglez <baptiste@jonglez.org> Reported-by: Erik Saule <esaule@bmi.osu.edu> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-18Add support for entering times in 24 hour formatWilliam Pettersson
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-07-07Add support for copy/paste registersLukas Fleischer
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.
