* Safety exit and read-only modeLars Henriksen2019-01-071-18/+35
| | | | | | | | | | | | | | | | | | | The key_generic_command() function provides a "safety exit" in case of online changes that should be dropped at exit when auto_save is on, or (NEW) should be saved at exit when in read-only mode. A check for unsaved changes has been added. The command prompt has been extended with minimal help information. After commit 05e0fd0 "Quit, autosave and interactive save" you could not leave calcurse in read-only mode with the quit command because the key_generic_quit() function interpreted IO_SAVE_CANCEL as a decision (by the user) to cancel a save-conflict and cancelled the quit as well. Now the function will quit unconditionally in read-only mode (as stated in the man page). In normal mode a check for unsaved changes has been added in case auto-save is off.

* Configuration variable for system eventsLars Henriksen2018-10-211-2/+4
| | | | | | | | After user acknowledgement a system event is deleted from the event queue. The configuration variable determines whether it is turned into an appointment (for later inspection) or not. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* System message queueLars Henriksen2018-10-211-0/+14
| | | | | | | | | | | | | | | The screen and user interaction is managed by the main thread. Other parts of calcurse (threads) wishing to use the screen or communicate with the user, must do it via the main thread. For this purpose the main input loop is extended with a message queue. A thread may insert a message in the queue. The main thread tests for messages before listening for user commands. If a message is present, it is displayed (in a popup window) for the user to acknowledge. Depending on the message other actions may be performed, e.g. the message could be turned into a "system appointment/event" and inserted among the usual appointments.

* Quit, autosave and interactive saveLars Henriksen2018-10-211-2/+11
| | | | | | | | Quitting calcurse with auto_save on may lead to an interactive conflict resolution for the save operation. When the result is a cancellation of the save, the quit command is also cancelled. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Error return code for io_reload_data()Lars Henriksen2018-10-211-1/+5
| | | | | | | | The return code from new_data() and io_load_data() is explicitly defined as a bit mask. A file access error is recognised and reported back to the user. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Distinguish between interactive and periodic saveLars Henriksen2018-10-211-3/+3
| | | | | | | | | | A new argument to io_save_cal() makes it possible for the periodic save thread to avoid 1) user interaction and 2) overwriting new data. At the moment the thread has no way to report on the result of the save. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Data save and removal of the progress barLars Henriksen2018-10-211-3/+5
| | | | | | | | | | | | | | | | | The function io_save_cal() saves apts, todos, configuration data and key bindings. The configuration and key files do not belong with the two data files, but the progress bar function assumes that all four files are saved in a fixed sequence. Since it is used nowhere else and contains unused parts, the function has been removed. A return code for file access error is introduced, and the EXIT macro moved to the command level in calcurse.c. Save of configuration and key data were already moved to the configuration menu in commit 0124618, A save refinement: no action if everything is unchanged.

* Move user information after save/reload to the command levelLars Henriksen2018-10-211-2/+42
| | | | | | | | | | | | | | | | | | | | | Moving user information to calcurse.c makes it easier to perform the actual save/reload operatons in io.c, e.g. it is possible to load instead of reload after a merge in conflict resolving. The save/reload operations are of such importance that the user should always be informed of the result (it's a bit disquieting when there is no reaction to a save or reload command). Hence, the save/reload status messages are no longer conditioned by show_dialogs(). No confirmation is asked for, so a message stays until the status bar is updated by another action. Care is taken to inform about save/reload actions that result in no change. Texts are kept concise because of the limited message area. When conflicts are present, whether saving or reloading, the "continue/merge/cancel" pattern seems easier to grasp.

* Only reload if data files were changed (replacement)Lars Henriksen2018-10-211-14/+1
| | | | | | | | | | | | | | This is a replacement for commits 57dd3d6 and 912124b. The idea is to move the check for modified files and the list initialization into io_load_data(), and let io_load_data() decide what to load. A new argument is used to force a load. The return code from new_data() (the renamed version of io_check_data_files_modified()) tells which files have changed.

* Reload data after resolving save conflict (improved)Lars Henriksen2018-10-211-1/+7
| | | | | | | | | | | | | | | After resolving a save conflict with the merge tool, a save operation has, in effect, occurred, and data files must be reloaded to import the result of the conflict resolution. This is a replacement for commit 2fe9c7e. The operations concerned with the user interface are kept out the io-operations (as in all other cases) and take place at the command-level in calcurse.c. and not at the io-level (io.c). Shorter, more concise prompt texts. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Handling of modified flagLars Henriksen2018-10-211-1/+0
| | | | | | | | | | The flag modified (io.c) keeps track of the memory state of data: modified == 0: unchanged since load or last save modified == 1: changed since load or last save It is now unset in io_load_data() and io_save_cal() only.

* Fix window update after hook executionLars Henriksen2018-10-211-2/+4
| | | | | | | | | | | | | | | | | | | | The introduction of hooks raised a problem with window updates. The diagnosis in commit feb059e8 (Fix segmentation fault on reload with pre-load hook) was right, the cure was wrong. The problem is wins_update(), not the listbox contents. The wins_update() call does not belong in wins_unprepare_external() (or in io_reload_data()), but at a higher level. It should be called _after_ reload, as indeed it is in key_generic_reload() when the listbox contents have been updated (todo as well as appointments). The call was introduced in commit 8ae75f3 without comment. The todo updates in io_reload_data() also belong in key_generic_reload() where they were before commit 7f06c252. When saving data, all panels must be updated in case a hook was executed. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Run pre-load hook before testing for modificationsLukas Fleischer2018-05-231-0/+4
| | | | | | | | | | | The pre-load hook is often used to manipulate the data files before loading, such as by synchronizing with a remote calendar. Make sure we always execute the pre-load hook upon reloads, even if the data files have not been modified. Fixes GitHub issue #98. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Support format strings when dumping imported itemsLukas Fleischer2016-02-111-1/+1
| | | | | | | | | | | | | | 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).

* Let SIGUSR1 trigger a reloadTim Hentenaar2014-10-101-0/+5
| | | | | | | | | | | | | 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.
