1a1a8bcdad Fix redrawing and scrolling for wide chars 
[ci skip]
 2012-09-05 20:42:54 -07:00
Kevin Lange
ac52d41144 Unicode Text Support 
* 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.

07955c83c6 Fix dozens of build warnings and other oddities. 
* 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.

8ed06789ed New debug printing facilities. 
- Can now register a userspace file descriptor as the output for kernel
  print statements through kprintf()
- Can set logging levels for debug print messages, which are separate
  from kernel log events and meant to be more readily visible. Log
  events are recorded in a buffer to be viewed later, though nothing
  actually using logging at the moment.
- Serial output is disabled by default now. You can enable it yourself
  by appending the logtoserial argument to the kernel on boot.

bba242dd62 Add a testing framework. 
This is an automated system by which we boot qemu headless and use the
serial line to capture output from a testing application that is started
on bootup, running with the VGA terminal shell. This might be expanded
to boot to the graphical display within VNC and perform more advanced
tests with the Python shim using a VNC module for Python; we'll see.

4f2c122af5 Context-based graphics library. 
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.
