Much in the calendar is based on the selected day, struct date
slctd_day, in ui-calendar.c.
On the screen it is highlighted with a deviating colour. The highlight
effect has been changed to a pair of red square brackets that do not
obscure the day colour.
The week number (in the frame) used to be that of the selected day, but
has no obvious relation to the days in the APP panel. It has been
replaced by the year day number of the selected day. The week numbers of
all visible weeks are displayed to the left of the calendar.
Dates are displayed also for the overlapping parts of the first and last
week of the month (which do not belong to the month).
Days are accessible in the appointments panel as well as in the
calendar. Hence, validation of days (= inside UNIX time limits) must be
extended from the calendar (in ui_calendar_move()) to include loaded
days (in day_store_items()).

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().

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()

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.

A scroll window consists of a pad to write on, and a window through
which to view the pad, the viewport. The pad may change in size when new
contents are loaded into the scroll window. If so, the pad size is set
with wins_scrollwin_set_linecount(). But the offset into the pad (the
top line to be displayed in the viewport) is not adjusted, although it
may not be appropriate for the new pad size. The same is the case when a
scroll window is resized and the viewport changes size. This is probably
the cause of the problem solved by commit 0b46ad4, Avoid blank space
after the last list box item, and the fix has been removed.
The wins_scrollwin_set_linecount() has been renamed
wins_scrollwin_set_pad() and sets size as well as offset. The offset is

Recurring appointments do not show up in the notification bar as next

The search function recur_apoint_starts_before() had a wrong second
argument, but is really of no use: the start time of a recurring
appointment is the start time of the very first occurrence (in the
past). A comparison against the item in the notify_app structure tells
nothing of the start time of the current day; at most it eliminates some
future recurring appointments. The function can be dropped, and the
entire recurring appointment list looked through.
The proper start time is found in the main search loop (and called
real_recur_start_time) and must be compared against the item in the
notify_app structure.
But because recur_apoint_find_occurrence() is limited to a particular
day (second argument), two searches are necessary to cover 24 hours.

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

calcurse deadlocks when
1) an upcoming appointment is on display in the notification bar,
2) an external command (like help) is started,
3) the time for the upcoming appointment arrives, and
4) the external command is exited.
The notification bar thread is stopped while the external command is
running. Upon exit from the external command, the n-bar thread is
restarted and calcurse locks.
The cause is the way in which the main notification bar thread is
stopped:
static pthread_t notify_t_main;
void notify_stop_main_thread(void)
{
if (notify_t_main) {
pthread_cancel(notify_t_main);
pthread_join(notify_t_main, NULL);
}
}
Objects of type pthread_t are opaque and should not be accessed
directly. Initially notify_t_main is an uninitialised static variable
(0), but later it has a value, which may or may not be the thread id of
the notification main thread.
Note that the thread id after exit of a thread may become the thread id
of a new thread. Thus the variable set when the thread is created, is
invalid after exit of the thread.
Specifically, the first time notify_stop_main_thread() is called (by
notify_start_main_thread() before the thread is created) is harmless
(because notify_t_main is 0). Calling notify_stop_main_thread() later
may be either
OK
because the main thread is running, or
harmless
because no thread with id notify_t_main is running: the two
functions will fail with return value ESRCH (no such process), or
fatal
because an unrelated thread with this thread id is running: it will
be cancelled, and the join may or may not succeed depending on
whether the thread is joinable or detached.
The "unrelated thread" could be the next-appointment thread,
notify_thread_app, launched by notify_check_next_app().
Always calling notify_stop_main_thread() before starting the main thread
becomes fatal when notify_check_next_app() is called shortly before
notify_start_main_thread(). This is the case in the scenario described.
The next-app-thread is then running when notify_stop_main_thread() is
called, and apparently it has the thread id of the old main thread
(confirmed by logging the return values from pthread_cancel() and
pthread_join(); the first succeeds while the second fails with EINVALID
which means that the thread is not joinable). The next-app-thread will
therefore exit without unlocking mutexes.
Ensure that notify_t_main, in case the notify main thread is not
running, has a value that it will never have when it is running. A
possibility is the thread id of the main() calcurse process (returned by
pthread_self()).
Check for this condition in notify_stop_main_thread() and set
notify_t_main when the thread is stopped.
Similar changes have been introduced for the periodic save thread and
the calendar date thread.

Internally characters (keys) have two representations: integers and key
names. Key names are characters strings, usually the name of the
character; e.g., the character A has the representations 65 and "A", and
the tab character the representations 9 and "TAB".
The function keys_int2str() turns the integer representation of a
key/character into the key name.
For display purposes the key names are usually confined to have display
width at most three. Some curses pseudo-keys have longer key names;
e.g., the back-tab character is "KEY_BTAB". A long key name makes a
character difficult to recognize in the status bar menu.
The key name of a multibyte, UTF-8 encoded character is the conventional
Unicode name of the code point; e.g., the character ü has key name
"U+00FC" because ü is the code point 0xFC. Most of these look alike in
the status bar menu.
The patch makes the key name of a multibyte character look like that of
a singlebyte character: the character itself, i.e. the key name of the

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

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.

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.

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.

Introduce a new function keys_wait_for_any_key() and use it instead of
wgetch() whenever the return value is discarded.

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").
