cgd 023e9f0649 C requires that labels be followed by statements. 2001-02-24 00:01:22 +00:00
mycroft 73ac8c709b Add a concept of the `background attribute'. This is the same as the
current attribute, but has all non-color flags turned off.  Use this when
doing erasure, as this allows us to optimize repainting in curses.

XXX The way the default attribute is handled is totally bogus and needs to
be fixed.

mycroft 2fd2b78c1f Only call the cursor method when the cursor state is actually changing.
This avoid corrupting VGA displays in text mode (e.g. the first character
of the prompt when you exit vi).

drochner 02e2e73771 fix VT300 tab stop report format 1998-06-29 21:14:40 +00:00
drochner bbb4f765cc Improvements to the VT100 emulation:
-display DEC special graphics and DEC technical characters as far as
  possible
-implement the font switching controls (need documentation!)
-behave well if double-width characters are requested
-simplify the state machine: store CSI command modifiers in variables
  instead of dedicating own states to each of them

drochner 68aabb6d21 First cut on a VT100 emulation.
It should be able to parse escape sequences up to VT300, but not everything
is implemented. Most notably, there is no font handling - all displayable
characters are handed to the graphics driver. To solve this, a serious
interface change to the graphics driver is needed (Unicode?).
