b72f9bea43 Sync OpenBSD patchset 162: 
More tty code tidying: move the saved cursor/region position (from before the
screen was updated) out of struct screen and into struct tty_ctx.

enum tty_cmd is only used as an index into the array of command function
pointers, so remove it and use the function pointers directly to represent
themselves.

fd0971542f Don't send initialisation strings is1/2/3 (barely anything else does) and move 
smcup to the first and rmcup to the last sequences output to the terminal. This

6db7bd6791 Try to guess if the window is UTF-8 by outputting a three-byte UTF-8 wide character and seeing how much the cursor moves. Currently tries to figure out if this works by some stupid checks on the terminal, these need to be rethought. Also might be better using a width 1 character rather than width 2. 2009-05-19 16:08:35 +00:00

Nicholas Marriott
84cde92c8f If redrawing the region would mean redrawing > half the pane, just schedule to 
redraw the entire window. Also add a flag to skip updating the window any
further if it is scheduled to be redrawn. This has the effect of batching
multiple redraws together.

b6450b167b Basic horizontal splitting and layout management. Still some redraw and other 
issues - particularly, don't mix with manual pane resizing and be careful when
viewing from multiple clients; generally cycling the layout a few times will
fix most problems. Getting this in for testing while I think about how to deal
with manual mode.

Split window as normal and cycle the layouts with C-b space. Some of the
layouts will work better when swap-pane comes along.

Nicholas Marriott
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.

not. This fixes copy and paste in xterm/rxvt.

959eeef505 FreeBSD's console wraps lines at $COLUMNS - 1 rather than $COLUMNS (the cursor can never be beyond $COLUMNS - 1) and does not appear to support changing this behaviour, or any of the obvious possibilities (turning off right margin wrapping, insert mode). This is irritating, most notably because it impossible to write to the very bottom-right of the screen without scrolling. To work around this, if built on FreeBSD and run with a "cons" $TERM, the bottom-right cell on the screen is omitted. 2009-02-11 23:16:45 +00:00

514fe11727 We are going to need the updated screen data for emulating the scroll region, 
which may involve changing the cursor position; however, the old (before
redraw) cursor position is necessary for writing to the tty. So, save it before
doing the redraw then update the internal screen then update the tty.

Not sure I like this solution but it does the job for now.
