* Implement scrolling in the appointments panelLars Henriksen2019-05-221-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With multiple days in the APP panel, up/down movements should change behaviour at the top and bottom of the list displayed, and load the previous/next lot of days. This requires that the move function returns the result of the operation. Furthermore, the ability to move the selection to the beginning of a day is needed when moving down (in order to move from the first day to the last day). For this reason a DAY_SEPARATOR has been inserted also after the last day of a lot. Appointments have a listbox height of three to separate them clearly when there is more than one in a day. This leaves a spurious empty line at the end of a day with appointments. The DAY_SEPARATOR height is reduced from two to one, and a new EMPTY_SEPARATOR of height one is inserted in any day with only events. When scrolling up the DAY_HEADING becomes visible when the selection reaches the first item of the day. The length of the separator (between events and appointments) is adjusted to leave a space to the window border at both ends, thereby making it a part of the day, not a separation between days. The dummy event must also be recognisable when not the selected item and is only inserted in interactive mode. The test for a saved selection must also recognise caption items which have item pointer NULL. The function day_get_nb() has been renamed day_get_days().

* Redesign selected-item implementation for the APP panelLars Henriksen2019-05-221-21/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The day vector, day_items, is displayed in the appointments panel; the selected day_item object is highlighted (when the panel has the focus). When items are inserted, edited, moved etc., and when the day is changed, the day vector is rebuilt and displayed anew. Problem: How shall the selection be set automatically in the context of the new day vector? In previous versions all of the above is mostly handled by the function do_storage() in calcurse.c The function saves data about the selection as needed, rebuilds the day vector, loads the listbox and sets the selection from the saved selection data. This works well in "single day" calcurse in cases where the selected item is present in the day vector both before and after the rebuild, or when the item ordering in the listbox is unaffected by the changes. But when a new item is added the selection cannot be set to the new object by do_storage(). Instead the necessary operations are performed by ui_day_item_add(), and do_storage() is bypassed. In general, when an item cannot be found in the new vector, the item which occupies the old place in the list gets selected, e.g. when an item is deleted. When an item is turned into a repeating one, the old item is deleted and a new is created. Here the new selection is not always the affected item, but in any case not far away. Generally, with only one day in the panel an erronous selection might not be noticed or be accurate by chance. In "multiple day" calcurse the existing scheme works less well; in addition the day vector may now contain more than one object that refer to the same event or appointment (recurrent items or multi-day appointments). The scheme has therefore been modified. The do_storage() function is no longer bypassed, but handles day vector rebuild, load of listbox and item selection exclusively. To make that possible, data about the selected item is no longer saved in a local automatic variable, private to do_storage(), but in an external static variable in day.c, which may be set not only by do_storage(). The variable is declared as static struct day_item sel_data; and used as follows: 1. On startup sel_data is initialized to empty (i.e. no selection). 2. In any operation involving the appointments panel: 2.1 Do the work and if necessary set sel_data. This is the case when deleting, adding or pasting an item, and when turning an ordinary item into a recurrent one. 2.2 Call do_storage(). 3. In do_storage(): 3.1 If sel_data is empty, set it to the current selection. 3.2 Rebuild the day vector. 3.3 Set the selection from sel_data. 3.4 Set sel_data to empty. Further remarks --------------- The selection is found in the new day vector by searching for the saved (order, item.<pointer>) pair. Previously the item.<pointer> alone sufficed and in some cases it still does. In case the item cannot be found, the selection stays in the same day as before the rebuild. An attempt at more consistently named APP-related functions has led to: ui_day_sel_date() replaces ui_day_sel_day() ui_day_get_sel() replaces ui_day_selitem() Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Introduce multiple days in the appointments panelLars Henriksen2019-05-221-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overview of existing implementation ----------------------------------- The APP panel displays the 'day_items' vector in the 'lb_apt' listbox. A listbox consists of a scrollwin (structure) in which a number of items is displayed. The listbox keeps track of: - the number of items - the selected item - the type of each item in an array type[] - the height of each item (ie. how many screen lines) in an array ch[] - how to display an item (on the screen) The latter three are handled by functions fn_type(), fn_height(), fn_draw(). The first two are used to fill in the corresponding array entry, type[] or ch[], for item number i, the third draws item number i. The items are taken from the global variables vector_t day_items int day_items_nb in day.c. Items include captions (DAY_HEADING, DAY_SEPARATOR). Everything is sorted for display (DAY_HEADING, events, DAY_SEPARATOR, appts). These are filled in ("stored") [by day_store_items() for the selected day in the calendar], before being "loaded" into the listbox. See do_storage() in calcurse.c and ui_day_item_add() in ui-day.c. New APP panel design -------------------- Several days are displayed in the APP panel by loading them with day_store_items(). With several days come several headings and separators. DAY_SEPARATOR is reinterpreted to separate days, and a new separator, EVNT_SEPARATOR, separates events from appointments. To sort everything, an 'order' member of type time_t is added to the day_item structure. It is set for headings and separators as well as for appointments and events as follows: item order --------------------- DAY_HEADING BGNOFDAY (= midnight) EVNT_SEPARATOR BGNOFDAY DAY_SEPARATOR ENDOFDAY event start time (midnight) appointment start time (first day) BGNOFDAY (following days, if any) The sort function day_cmp() (used by vector_sort) is extended to sort by order first. The order field always indicates the day to which an item belongs. This comes in handy, because with several days in the APP panel it is necessary to distinguish between the selected day in the calendar and the selected day in the APP panel. This raises the question which day should actions (commands) operate on: the one selected in the calendar or the one selected in the APP panel? Unquestionably the one on the APP panel which is the one tacitly implied. In most cases it is not a problem, though, because actions work on the selected item and the selected day does not come into play. But in some cases it does: delete item When deleting an occurrence of a repeated item, the selected day is the exception day to add. view item day_popup_item() needs the day of the selected item for display of correct start/end times. cut/paste item Paste needs the selected day in which to paste. add item The day of the new item is taken from the calendar. Instead a dummy event is inserted in an empty day. This makes the day selectable, which is otherwise impossible with only the DAY_HEADING displayed. The dummy event is selectable but cannot be edited or deleted (but viewed or piped). With more than one day in the day_items vecter, an appointment spanning more than one day may occur more than once in the vector (with start/end times suitably adjusted for display). A day_item is no longer (always) identified by the aptev_ptr (item) value. Instead the combination (order, item.<ptr>) is used; order is roughly the day.

* Simplify day storageLars Henriksen2019-05-221-8/+3
| | | | | | | | | | | The function day_process_storage() is a wrapper for day_store_items(). It has an unused second argument, and is only used twice to load the selected day. It has been removed. A new function, get_slctd_day(), is the equivalant of get_today() and replaces the very awkwardly named ui_calendar_get_slctd_day_sec(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* 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

* 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).

* 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>
