2a9d697771 Invalidate the cursor when we think we should have wrapped. 2017-03-15 15:22:14 +00:00
nicm
3c3c08b6d9 Try to avoid moving the cursor to the start of the next line when
printing cells if it is already at the very end of the line and the
terminal will wrap it to the next line itself, this means terminals
still see it as a wrapped line for the purposes of their own mouse
selection. Reported by millert@.

are the keys when it is on.

82db1fa9e5 There are buggy terminals out there that do not move the cursor to 0,0
after CSR, so invalidate the cursor position rather than assuming 0,0.

d22c15107b Don't use a bufferevent for the tty, so we can keep better track of what
is being written and when.

Also a manpage typo fix from jmc@.

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.

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.

0ace779cde Initial attempt to make use of left and right margins if the terminal
supports them (that is, if it advertises itself as a VT420 - probably
just xterm). These are the vertical equivalent of the scroll region and
allow much faster scrolling of panes that do not take up the full width
of the terminal.

d413a945ac Don't make assumptions about line wrap on !xenl terminals, means that
using a wrong TERM without xenl is not so broken if used on a sensible
terminal.

4179b42424 Add support for BCE (background colour erase). This makes various escape
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.

On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

Mostly written by Sean Haugh.

0f73af876f Don't update cells in each block of data read from a pane immediately,
instead track them as change (dirty) and update them once at the end,
saves much time if repeatedly writing the same cell. Also fix comparison
of cells being equal in a few places (memcmp is not enough).

7d105738b6 Send two cub1 instead of using cub for moving the cursor two left. This
is normally better because using cub1 will be ^H^H (so two bytes) but
cub would be ^[[2D (four).
