Creating a window potentially runs hooks, which themselves could
trigger shell evaluation, which could handle urgent input events
such as a resize, while waiting for the shell to finish. When that
happens, the client had a temporarily null window as it had already
released its own window.
Fixes#2225
Window can be resized with an "offset_pos" flag, which means that
the resize took place on the top left corner of the window, leading
to a change in current window position. This is treated as temporary
and the position change is stored in a m_position_offset field.
That allows the ncurses UI to offset the position when it displays
a Search menu, so that the window does not constantly scroll when
the search menu open/closes. The window will only scroll if it needs
to in order to keep the main selectin visible.
Add a UserInterface::is_ok method and return false on
SIGHUP/stdin closing/socket dropping
This should be cleaner and more robust than the previous SIGHUP
handling code.
Fixes#1594
set-face now takes a scope argument, and faces can be overridden on
a buffer or window basis.
colorscheme apply on global scope, which should be good enough for
now.
Fixes#1411
Pressing Y or N will set the buffer (or window, if it is set at that
scope) autoreload option to the corresponding value, avoiding infinite
loops where a file getting constantly modified prevents the user from
using Kakoune.
Reseting normal mode will enable normal mode, which will trigger
a check for buffer modification. We do not want that check to
happen as we are trying to close the info box. Doing that mode
reset first will prevent the check from happening (as the info
box is already displayed), and will correctly hide it afterwards.
Fixes#1809
Do not implicitely change new clients selections to target coordinates
when the user did not specify them, so that we can re-use the selections
from the found free window, which is the generally desired behaviour.
This round trip through an input callback expected to call
is_key_available and get_key was overcomplicated, just send the
keys as they arrive, the client is already buffering due to urgent
event mode.
If a shell commands takes more than 1s to execute, a message will appear
on the status line notifying the user, along with the time Kakoune has
been waiting for.
Add a ColumnCount type and use it in place of CharCount whenever
more appropriate, take column size of codepoints into account for
vertical movements and docstring wrapping.
Fixes#811
Client quitting no longer immediately unwinds, client is just pushed
for deletion until we get back to the main loop, similarly to what
happens for buffer and window deletion.
