I am going to replace it after I finish making the ANSI escape parser
modular again (it became a bit less modular during the development of
this terminal).
These changes are part of an effort to make the terminal more efficient.
Another goal is to make the terminal use the "new-style" compositor
interface, which is still in development.
Major speed improvement, though it might make things like "Scale
windows" look a bit less polished; windows that are scaled up in scale
mode are rendered with bilinear scaling. Will probably replace with the
FAST/GOOD macros later.
Also, add the framework for Alt+Tab window picking (not implemented yet)
Also fix the mouse to account for this... development.
Smoother mouse movement all around, though it may make things slightlys
lower by spamming lots of mouse packets. Just write good clients and
everything will be fine...
There are both some good changes and some terribly hacky changes in this
commit.
- Server uses a different struct than client now for windows, so
arbitrary compositor things like effect parameters can be added
without having to rebuild everything. That's good.
- Client window structs no longer attempt to track or use window
locations. That's good.
- Windows do not destroy in response to the destory command, but rather,
a special animation is triggered; the end state for this animation
calls the actually window destruction code. That's a hack.
- Animations are based on rendered frames, not on time. That's a hack.
* Dumb bounding box top_at logic replaced with select buffer
* Select buffer rendered through cairo with AA disabled
Using rectangles for window shapes - this should easily
be expandable to 1bpp bitmaps. Currently, the select buffer
is very inefficient, using twice the space it needs (plus,
it's double buffered, so in reality, 4x the space needed),
however, it's also very accurate and fast, and I like that.
* Window rotation is controlled through Ctrl+Shift+{z,x,c} where
z = rotate 1 degree left
x = rotate 1 degree right
c = reset rotation
* Input is remapped based on window rotation, so you *can* use the
draw app, and it is totally epic.
* login should set some environment variables now
* init should start terminals as login shells, so --single doesn't really
mean "single user" any more, just sorta single terminal session
* system() should work now since esh now accepts -c; not that vim is
still going to be unhappy because it does crazy shit.
This fixes a bug in Vim and one introduced an hour ago in Nyancat.
This bug was also present in early versions of bim.
Problem: If the background is set to 16 (all black) explicitly, we still
treat it as if it is the default color and thus make it transparent.
This is wrong, only the default background, as set by resetting either
the bg itself (with mode 49) or the full display parameter set (with 0)
should show up transparent.
Solution: By using flag to indicate wether the background is "default",
we can detect other uses of background color 16 without having fudge
with other colors like 0. The flag is ANSI_SPECBG, where SPEC means
"special", and thus it is set any time the background changes
explicitly, and is unset in raw cells or places where we are in default
mode.
Also, sleep() as a function (implemented by way of nanosleep) and new
absolute and relative sleep system calls added to newlib.
[ci skip] I damn well know this is going to break CI.
