e63567d51c Support "alternate screen" mode (terminfo smcup/rmcup) typically used by full
screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.

1b245388b5 Proper support for tab stops (\033H etc), using a bitstring(3). Makes another
vttest test happy.

cd71a13a14 Okay, so I screwed up when testing this, doh. Unbreak so that CAN/SUB actually
do cancel the sequence, and tweak to make the code more clear.

4eed190649 Oops, CAN and SUB should abort the sequence (return to first state), not remain
in the same state.

c3c14817c9 More input compatibility love. Support C0 within escape sequences, and the C0
control character VT (vertical tab, \013), which is treated as LF like
VT102. Makes another vttest happy.

93631b3ca7 Implement the DEC alignment test. With the last change this is enough for the
first cursor test in vttest (in ports) to pass; it still shops a few more
problems though.

7597cb6834 Pass window titles through vis(1). <0x20 is dropped anyway by the input state
machine but top-bit-set nonprintables could cause trouble, and they are neater
like this anyway.

cf7b384c43 Better UTF-8 support, including combined characters. Unicode data is now stored
as UTF-8 in a separate array, the code does a lookup into this every time it
gets to a UTF-8 cell. Zero width characters are just appended onto the UTF-8
data for the previous cell. This also means that almost no bytes extra are
wasted non-Unicode data (yay).

Still some oddities, such as copy mode skips over wide characters in a strange
way, and the code could do with some tidying.

6c0728fe07 Step 2 of the Grand Plan To Make UTF-8 Better.
Split grid into two arrays, one containing grid attributes/flags/colours (keeps
the name grid_cell for now) and a separate with the character data (called
text). The text is stored as a u_short but is treated as a uint64_t elsewhere;
eventually the grid will have two arrays.

I'm not happy with the naming so that might change.

Still need to decide where to go from here. I'm not sure whether to combine
the peek/set functions together, and also whether to continue to treat the
text as a uint64_t (and convert to/from Unicode) or make it a char array
(of size one when UTF-8 disabled, eight when enabled) and keep everything
as UTF-8.

Also since UTF-8 will eventually become an attribute of the grid itself it
might be nice to move all the padding crap into grid.c.

162bacdcd9 Window splitting. Two vertical panes fixed 50% each. This is a huge diff, still a couple of bugs (notably heap corruption somewhere causing segfault on exit). 2009-01-11 23:31:46 +00:00
