1811dc5271 Another helper function to write to terminal and log. 2017-02-08 23:53:03 +00:00

2f854969ff Do not adjust region lower by pane offset when scrolling up, it is 
already an absolute position.

05802a6fe3 window_copy_pagedown shouldn't reset the mode anymore, instead let the 
caller do it so it can free the marks. Problem reported by attila at
stalphonsos dot com.

e100d465da Add support for scroll up escape sequence (CSI S) and use it when 
possible instead of sending individual line feeds.

13a0b6bb3f Collect sequences of printable ASCII characters and process them 
together instead of handling them one by one. This is significantly
faster. Sequences are terminated when we reach the end of the line, fill
the internal buffer, or a different character is seen by the input
parser (an escape sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).

9cc02d1498 Trying to avoid the occasional newline by saving the last cell on screen 
is not actually helping us much and just adds complexity, so don't
bother.

6ea36afc4b DECSLRM in xterm(1) appears to have a quirk where it can generate an 
extra scroll of the entire terminal; issuing DECSTBM first prevents
this. Do that for now.

9491a5c1cf Unfortunately DECFRA does not handle default colours properly (it does 
not reset colours when in SGR 0), so we can't use it without more
trouble than it is worth. Abandon the idea for now.

d60e585d9e Use DECFRA on VT420 compatible terminals (so, xterm) and ED on all 
others for clearing panes.

7d23d019c0 Add a window or pane id "tag" to each format tree and use it to separate 
jobs, this means that if the same job is used for different windows or
panes (for example in pane-border-format), it will be run separately for
each pane.

dd0c814779 Implement "all event" (1003) mouse mode but in a way that works. The 
main issue is that if we have two panes, A with 1002 and B with 1003, we
need to set 1003 outside tmux in order to get all the mouse events, but
then we need to suppress the ones that pane A doesn't want. This is easy
in SGR mouse mode, because buttons == 3 is only used for movement events
(for other events the trailing m/M marks a release instead), but in
normal mouse mode we can't tell so easily. So for that, look at the
previous event instead - if it is drag+release as well, then the current
event is a movement event.
