* Update UTF-8 base codeLars Henriksen2017-12-072-23/+11
| | | | | | | | | | UTF-8 encodes characters in one to four bytes (since 2003). Because 0 is a valid code point, the decode function utf8_ord() should return -1, not 0, on error. As a consequence utf8_width() should return 0 for a continuation byte (as it did previously). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* calcurse-caldav: Avoid corrupting the sync DBLukas Fleischer2017-11-231-2/+9
| | | | | | | | | When importing an iCal event via calcurse fails (i.e. does not return a single object hash), do not write anything to the synchronization database instead of blindly appending the entry, thereby potentially corrupting the database. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Do not prompt when non-interactive import failsLukas Fleischer2017-11-231-17/+11
| | | | | | | | | | When running calcurse in non-interactive mode, we should not expect any user input. This is even more important in the case of iCal imports which are used by calcurse-caldav to import events from CalDAV servers. Partly fixes GitHub issue #73.

* Check for the year span 1902-2037Lars Henriksen2017-11-233-15/+34
| | | | | | | | | | | | | 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.

* Function cleanup in custom.cLars Henriksen2017-11-232-42/+39
| | | | | | | Remove two remnants: custom_color_theme_name() and custom_set_swsiz(). Make static and rename custom_confwin_init() into confwin_init(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix help for nine actionsLars Henriksen2017-11-151-4/+18
| | | | | | | | | | | | Seven actions were absent from display_help(). This meant that commands like ':help ^P' did not work. They now refer to general.txt, but are not all described there. For two actions, generic-copy/paste, the file name was misspelled. This solves Github issue #44. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Revert "calcurse-caldav: Add --password command line argument"Lukas Fleischer2017-11-081-5/+3
| | | | | | | | | | This reverts commit efd76a0d995292e48f5466fccada4901618f7d97. Passing passwords as command line arguments is not a good idea, since they may appear in process listings which are potentially visible to other users logged into the system.

* calcurse-caldav: Use /usr/bin/env in the shebangStefan Hagen2017-11-051-1/+1
| | | | | | | | | | | | It is best practice to use `/usr/bin/env python3` instead of a hard coded path. This will search for "python3" in the PATH environment variable. Most Linux distributions install python to "/usr/bin". Most BSDs to "/usr/local/bin". Signed-off-by: Stefan Hagen <github@textmail.me> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Detect error on character inputLars Henriksen2017-10-291-1/+5
| | | | | | | | | | Previously an error from the character input routine wgetch() was silently ignored. It should still be ignored, but must explicitly be detected in order to be ignored. The issue came up in connection with terminal window resize. For whatever reasons ncurses returns ERR (as well as KEY_RESIZE) when wgetch() asks for input after a resize. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix multiple popup windowsLars Henriksen2017-10-293-11/+19
| | | | | | | | | | The window was not deleted if an "already in use"-key was detected, and a new one was created as the loop was reentered. Create/delete of the popup are moved outside the loop. A redrawwin() call is needed to have the window displayed again. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* 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 Fleischer2017-10-263-8/+13
| | | | | | | | | 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.

* Remove recognized keys checkLars Henriksen2017-10-261-36/+12
| | | | | | | All keys known by ncurses can be bound. Thus the check for not recognized keys in custom_keys_config() becomes superfluous. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Support key bindings for all escape keysLars Henriksen2017-10-232-84/+95
| | | | | | | | | | | | | | | | | | | | | All key names for ordinary ASCII keys as well as for escape keys (pseudo keys) are cached in a lookup-table, keynames[], at startup. Mapping between key names (strings) and key codes (integers) in keys_str2int and keys_int2str) is performed through this table. The key names used are those returned by the keyname() function of ncurses. But to accommodate some of the names to the three-letter space available in the status menu, four ordinary keys and the most common escape keys have calcurse abbreviated names: ESC, TAB, RET, SPC and LFT, HOM, PgU, INS, F1, etc. All keys known by ncurses can be bound. Thus the check for not recognized keys in the key configuration menu becomes superfluous. The only keys that cannot be bound, are those escape keys not known to ncurses, i.e. not described by the terminfo database for the terminal type in use.

* Updates for UTF-8 key bindingsLars Henriksen2017-10-232-38/+38
| | | | | | | | | | | | | | | | | | | | | Code point mapping adjusted for multibyte characters to avoid the ncurses range 0-KEY_MAX. This includes three fixes: 1) test sequence in keys_assign_binding(), 2) reassemble multi-byte character in keys_wgetch(), 3) check for already in use in keys_assign_binding(). Rearrangement of code. The introduction of allocated memory in keys_int2str() has as a consequence that check for recognized ncurses pseudo characters now are in two places: keys_str2int() and custom_keys_config(). The latter was moved from keys_wgetch() to improve user information. More informative warning messages in custom_keys_config(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Do not tie ISO 8601 week numbering to MondayLars Henriksen2017-10-171-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | The week number in the calendar panel is calculated according to ISO 8601. Hence, Monday is the first day of the week and the week number changes from Sunday to Monday. However, calcurse ties the week number not to Monday, but to the first day of the week as configured for display. Thus, when Sunday is shown as first day of the week, the week number is correct for Sunday, but wrong for the rest of the week (one behind). With this patch the week number always follows the mon-sun week as required by ISO 8601. A side effect is that when Sunday is displayed as first day of the week, and Sunday is the selected day, the week number displayed is invalid for the rest of the week (but changes to the correct one when the selected day moves forward). This raises the question whether the week numbering scheme should follow the "first day of the week" choice and use the American week numbering scheme instead of ISO 8601 when Sunday is the first day of the week. But that is for the future. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add calcurse-dateutilLukas Fleischer2017-09-081-0/+77
| | | | | | | | | | | | | | | | | Add a script to iterate over a certain date range, performing operations on each of the dates and printing the result. An additional string can be appended to each of the printed lines. The script can be used to create "extended recurrent events". For example ./calcurse-dateutil.py --date 2017-01-01 --range 365 --unique \ --append ' [1] Test event' bom next-weekday 3 skip-days 14 can be used to print an event for each third Thursday of each month in 2017.

* Add OAuth2 support for calcurse-caldavRandy Ramos2017-09-082-0/+124

* Refactor calcurse-caldav to use httplib2Randy Ramos2017-09-082-29/+17
| | | | | | | | | | This will allow much more flexibility and less code duplication when adding OAuth2 support. OAuth2 support will require this library as it is a dependency of oauth2client.

* Change remote_wipe to delete objects individuallyRandy Ramos2017-09-081-1/+3

* URL encode href before saving to sync.dbRandy Ramos2017-09-081-1/+2
| | | | | | | | | | When pushing objects, the unencoded uri path would be saved into the sync.db.

* git-version-gen: Add default versionLukas Fleischer2017-09-081-8/+4

* Use a shared input/output mutexLukas Fleischer2017-09-082-16/+23
| | | | | | | | | 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>
* Interrupt periodic save when launching processLukas Fleischer2017-09-081-0/+4
| | | | | | | | To avoid interactions between the periodic save thread and external processes, stop the periodic save thread before launching an external program and restart the thread as soon as the program is terminated. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Only reload if data files were changedLukas Fleischer2017-09-083-7/+15
| | | | | | | | 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>
* Factor out check for external modificationsLukas Fleischer2017-09-081-15/+20
| | | | | | | | Move the check to compare the stored hashes of the data files with the current hash to a separate function. This makes the code easier to read and reusable. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Do not blindly overwrite files when savingLukas Fleischer2017-09-081-0/+59
| | | | | | | | | When reading the data files, compute a cryptographic hash of the file contents and store it. When saving the files later, ensure that the hash still matches the current file contents. If it does not, show a warning to the user and ask whether she wants to execute the merge tool.

* Use .new as file extension when mergingLukas Fleischer2017-09-081-15/+15
| | | | | | | | Using the file name extension .sav and naming the variables "backup" is slightly misleading, since the affected files actually contain the updated content and not some old snapshot. Use the term "new" instead. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
