Fix the problem caused by wrong cursor coordinates. No more messing with
the main cursor, instead the cursor is saved when receiving a pre-edit
text update and used for drawing later.
Update the overlay to the last visible cursor position before rendering
to ensure it always moves with the cursor. Finally, draw the overlay
after line rendering is complete, and restore the line buffer after
updating the rendered data to ensure that the line text being read is
correct at all times.
This also improves performance by only rendering once when changes are
made, eliminating the need to repeatedly disable and draw after various
commands and not even comprehensively.
This commit introduces the Unicode placeholder image placement method.
In particular:
- Virtual placements can be created by passing `U=1` in a put command.
- Images with virtual placements can be displayed using the placeholder
character `U+10EEEE` with diacritics indicating rows and columns.
- The image ID is indicated by the foreground color of the placeholder.
Additionally, the most significant byte of the ID can be specified via
the third diacritic.
- Underline color can be optionally used to specify the placement ID.
- A bug was fixed, which caused incomplete image removal when it was
overwritten by another image with the same ID.
Fix the maximized window can't occupy full screen space when window
decoration or title bar is hidden.
Fix resize_in_steps being applied even when window is maximized.
Allows to specify `os_window_state` in startup session file.
Apparently on FreeBSD one cannot unlink shared mem if it is not created
with write permissions.
Adding IWRITE to the permissions when creating the shared memory is
harmless. It means any process running as the user can either write to
the file or delete it. Deleting was already possible except on FreeBSD.
As for writing, it's needed on FreeBSD for shared memory to be useable
at all, and since processes running as the user can already completely
access all their data, kitty config files, tty pipes, etc. allowing them
to write to the SHM used here doesnt grant any significant new
capability, since they could just write to ssh.conf in the kitty config
folder to get the ssh kitten to do whatever they like.
Fixes#5928
It's easier to type, and cuter.
Also, most, if not all of the TUI parts of
kitty's kittens will eventually be re-written into kitten.
The only downside I can see is that we cant tab complete kitty
anymore, but hopefully there will be less reason to run kitty
from the shell as command line tools migrate to kitten.
Meowrrrr!!!
