- Desktop icons use the shadowing
- The login screen uses shadows instead of poorly-executed strokes
- The blur_test app has been updated to show multiple blur levels,
but does not use the library function.
Kernel driver sends raw scancodes, compositor or terminal handle the
rest. Support for F* keys will be added soon, in the mean time userspace
applications can know about the status of modifiers (control, shift,
alt, and super).
Compositor actions have been changed to Alt+Left Click for move and
Alt+Middle Click for resize. I'll work on adding more mouse events once
I get them to be faster (they're annoyingly slow at the moment... I want
more accuracy and less latency).
Also add functionality to the terminal to toggle it on and off.
There's a small, but nice-to-have performance increase from disabling
alpha transparency in the terminal.
Also, the display server sets DISPLAY=... to the shmem endpoint for the
compositor, so if getenv("DISPLAY") returns a pointer, you can assume
you are in a graphical environment, instead of having to rely on things
like arguments. Good for those applications that want to be able to run
both full-screen and windowed.
* Patched crt0 to support a pre_main
* pre_main sets up environment variables, can do other things later,
but then just jumps to main with the same arguments.
* Updated a bunch of apps to pass environment variables around.
The compositor itself still needs work, but the compositing engine
within now does full blitting and is faster than the old method.
Transparency is now supported properly, though telling the compositor to
use it on a window will degrade performance. One terminal is usually
okay, and everything runs faster than it did before; two terminals is
pushing it; three will make you very sad. The stacking logic has also
been updated. Presumably, alpha blitting for transparent windows could
be done with SIMD instructions and be extremely fast.
All graphics libraries have also been updated to (hopefully) work
properly with alpha bits.
* Also cleaning up some kernel logging options here.
* You can log in as local or root with passwords local and toor
* Graphical sessions are still buggy, so don't kill that terminal.
* Some applications now support UTF-8 text through the use of a very
simple decoder.
* The terminal uses a slow, but accurate method to determine the width
of a character the first time it is printed to the screen. Characters
are now stored in the terminal in two bytes, rather than one, and may
in the future be increased to 3 or 4 bytes to ensure support for
Unicode supplemental planes.
* A simple font-fallback method is employed in the applications that
support unicode that will make use of the VL Gothic fonts if the
DejaVu font does not have a character. No guarantees are made for
support of writing systems other than extended Latin and Japanese.
* Finally bring syscall.h up to speed and include all syscalls in the
syscall module of the C library.
* Remove the third-party obfuscated C demos (we have nyancat, good
enough)
* Fix userspace apps to build without complaining about undeclared
strtok_r by disable __STRICT_ANSI__
* Fix .eh_frame by including the proper stuff with libgcc.
All graphics library commands now take a gfx_context_t pointer, which
points to a simple datastructure describing a rendering context (width,
height, depth, total size, front buffer, backbuffer; where backbuffer =
front buffer when not in double-buffering mode, thus we always render to
backbuffer except on a flip). This may have caused a minor speed
reduction, but I don't really care as it's far more important that we
support multiple graphics contexts.
TODO:
- Shared Memory Fonts library (there are a couple of apps that use these
so-called "shmem fonts" on their own; we need a dedicated library for
them)
- Break off "TTK" GUI toolkit into its own library. Since it's just a
callback-based button framework, this shouldn't be too hard right now.
Also, with the previous tick, I'll be able to put labels on controls
and start using text in more places.
This update includes support for shadow passwords, stored in
/etc/master.passwd, as well as support for an /etc/passwd file
containing user/uid/full name/shell associations, which are used by the
shell to get your username for display purposes, as well as by whoami
for the same reason. The login tool does not yet select the right shell
though this is planned.
* root's password is `toor` (a throwback to older times)
* local's password is `local` (because it's obvious)
