* Use a shared input/output mutexLukas Fleischer2017-09-081-2/+0
| | | | | | | | | Replace the save mutex with a common mutex, which is locked whenever read or write operations on the data files are performed. Also, since this mutex is an implementation detail, mark the locking functions static and remove them from the header file. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Only reload if data files were changedLukas Fleischer2017-09-081-1/+1
| | | | | | | | Instead of blindly reloading data in io_reload_data(), compare the stored hashes of the data files with hashes of the current file contents and only reload if any of the hashes differs. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make the day heading position configurableLars Henriksen2017-09-081-0/+7
| | | | | | | | | The date at the top of the appointments list may be positioned either to the left, in the middle or to the right. Default is to the right. Can be configured from the general options menu. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Remove phase of moon featureLars Henriksen2017-09-081-1/+2
| | | | | | | | | | 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>
* Add a function to wait for any key pressLukas Fleischer2017-09-031-0/+1
| | | | | | | 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>
* Add support for UTF-8 key bindingsLukas Fleischer2017-08-301-1/+3
| | | | | | | | | | | | | | | | A new function keys_wgetch() reads full UTF-8 characters instead of single ASCII characters only. Key bindings for regular ASCII characters are stored in a hash map while the actions of keys with higher code points are stored in a linked list for space efficiency. The key serialization methods are updated to handle UTF-8 characters as well; extended UTF-8 characters (characters not in the ASCII range) are serialized by using the hexadecimal representation of the corresponding code points (e.g. "U+00E4").

* Use nl_langinfo() for month and day namesLars Henriksen2017-08-281-3/+0
| | | | | | | | Use the locale setting to fetch the month names and abbreviated day names. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make heading in appointments panel configurableLars Henriksen2017-08-281-0/+4

* Replace parse_datetime() constants by named flagsLukas Fleischer2016-10-101-0/+4
| | | | | | | 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>
* Factor out parse_datetime()Lukas Fleischer2016-10-091-0/+1
| | | | | | | | 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>
* Fix out-of-bounds memory accessLukas Fleischer2016-09-281-0/+2
| | | | | | | Do not try to access freed day items. This also fixes unexpected selection changes after modifying appointments or events. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Do not assume that days always have 86400 secondsLukas Fleischer2016-03-271-0/+1
| | | | | | | | 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/+2
| | | | | | | 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>
* Refactor UTF-8 choppingLukas Fleischer2016-02-261-0/+1
| | | | | | | Add a function that makes sure a string does not exceed a given display size. If the string is too long, dots ("...") are appended. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make automatic selection of appointments/events smarterLukas Fleischer2016-02-161-0/+3
| | | | | | | Keep item selection when an item is moved (e.g. by changing the start time or description). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Support format strings when dumping imported itemsLukas Fleischer2016-02-111-3/+5
| | | | | | | | | | | | | | In commit 3eae7ce (Add --list-imported command line option, 2016-01-12), we added an option to print the hashes of imported items to stdout. Extend this command line option such that it dumps the items using the specified formatting strings. With the new behavior it is, for example, easier to check items for import errors. Also, rename the option from --list-imported to --dump-imported (it is not part of any official release yet so we do not need to care about backwards compatibility). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Refactor grep modeLukas Fleischer2016-02-051-0/+2
| | | | | | | | | 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>

* Support sending notifications for all appointmentsLukas Fleischer2016-01-271-0/+4
| | | | | | | | | | In 45417bc (Add configuration option to notify all appointments, 2011-07-31), we added an option that allows for choosing whether the user receives notifications only for flagged or only for unflagged appointments. Convert this setting into a three-state option and allow the user to additionally enable notifications for *all* appointments. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make automatic selection of todo items smarterLukas Fleischer2016-01-181-1/+1
| | | | | | | | * Automatically focus new todo items after adding them to the list. * Keep selection when an item is moved (e.g. by changing its priority). * Focus the next item in the list when an item is removed. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Improve ordering of todo itemsLukas Fleischer2016-01-181-0/+1
| | | | | | | | * Show uncompleted items first. * Order uncompleted and completed items by priority. * Order items with the same priority alphabetically. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Save active view on the todo panelLukas Fleischer2016-01-181-0/+2
| | | | | | | | Add a configuration option appearance.todoview and use it to automatically save the currently active todo panel view and restore it when restarting calcurse. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Use a separate field for the completed statusLukas Fleischer2016-01-181-1/+2
| | | | | | | Add a new field that indicates whether a todo item is completed or not instead of encoding completed todo items by negative priorities. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add a "hide completed" view to the todo panelLukas Fleischer2016-01-181-2/+11
| | | | | | Add a second view to the todo panel that hides all completed items. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Export item UIDs upon requestLukas Fleischer2016-01-151-2/+2
| | | | | | | Add a new --export-uid command line option that adds each item's hash to the UID property when exporting. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add --list-imported command line optionLukas Fleischer2016-01-131-2/+2
| | | | | | | When this option is used together with -i/--import, the object identifiers of imported objects are printed to stdout. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add command line option to suppress dialogsLukas Fleischer2016-01-131-0/+2
| | | | | | | 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/+2
| | | | | | | | | 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 Fleischer2016-01-131-0/+5
| | | | | | | Add new format specifiers to print the raw item representation or an object's hash value. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Implement utility functions for dynamic stringsLukas Fleischer2016-01-131-0/+16
| | | | | | | | Introduce support for strings which support concatenating the current value with a printf-style formatted value, thereby growing in size dynamically. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add pre-save and post-save hooksLukas Fleischer2016-01-071-0/+6
| | | | | | | | | | | | | This adds support for hooks which are executed before/after saving calcurse data. Hooks can be placed under hooks/pre-save and hooks/post-save in the data directory and need to be executable. Potential use cases include: * Automatically commit any changes to the data files using a VCS. * Automatically sync with some sever component on data file changes. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Split out code for drawing week numbersLukas Fleischer2015-04-101-0/+1
| | | | | | | This allows for easily adding week numbers to other panel modes, such as the monthly view. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use time_t instead of long in several placesLukas Fleischer2015-02-241-16/+13
| | | | | | | 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/+2
| | | | | | | | 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/+1
| | | | | | | | | | | | | | 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>

* Let SIGUSR1 trigger a reloadTim Hentenaar2014-10-101-0/+1
| | | | | | | | | | | | | 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.

* Factor out item reload codeLukas Fleischer2014-10-101-0/+1
| | | | | | | 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>

* Allow for filtering TODO itemsLukas Fleischer2014-08-061-7/+21
| | | | | | | | | | | 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>
* Add pattern filter optionLukas Fleischer2014-08-061-1/+2
| | | | | | | 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>
* Add item filtersLukas Fleischer2014-08-061-5/+24
| | | | | | | | | | | | | | | | | 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>
* Refactor new_tempfile()Lukas Fleischer2014-07-221-2/+1
| | | | | | | | 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>
* Add vasprintf() and asprintf()Lukas Fleischer2014-07-221-0/+2
| | | | | | | | | 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.
