3ea5e06bfb Support DECSCUSR sequence to set the cursor style with two new 
terminfo(5) extensions, Cs and Csr. Written by Ailin Nemui.

944b5e6fa0 Support xterm(1) cursor colour change sequences through terminfo(5) Cc 
(set) and Cr (reset) extensions. Originally by Sean Estabrooks, tweaked
by me and Ailin Nemui.

79e30daeae Support passing through escape sequences to the underlying terminal by 
using DCS with a "tmux;" prefix. Escape characters in the sequences must
be doubled. For example:

$ printf '\033Ptmux;\033\033]12;red\007\033\\'

Will pass \033]12;red\007 to the terminal (and change the cursor colour
in xterm). From Kevin Goodsell.

c36f67a288 Fix a typo that meant we did not reset the background colour when it was 
omitted in a 256-colour SGR ([48;5m). From Yusuke ENDOH.

b6bb350289 Use input_clear to reset the APC, DCS, OSC state or it could be reused

8f8e81c0c9 Mouse highlight mode (1001) requires a program to cooperate so 
supporting it through tmux is not as easy as this, remove it for now.

ac3b78a841 Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262 
and supports larger terminals than the older way.

If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.

With help and based on code from hsim at gmx.li.

f7c42c21ba Support all four of the xterm mouse modes. Based on a diff from hsim at 
gmx.li.

colours).

15a64b805e Massive spaces->tabs and trailing whitespace cleanup, hopefully for the last 
time now I've configured emacs to make them displayed in really annoying
colours...

a02c7e804c Convert the window pane (pty master side) fd over to use a bufferevent. 
The evbuffer API is very similar to the existing tmux buffer API so this was
remarkably painless. Not many possible ways to do it, I suppose.

1af09d6330 Try to reduce the UTF-8 mess. 
Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.

Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.

71dc6e04e8 Handle DECCOLM by just emulating its side-effect of clearing the screen. 2009-10-13 15:23:13 +00:00

8608c6970d When backspace is received at the beginning of a line and the previous line was 
wrapped, move the cursor back up to the end of the previous line.

Another one of the forgotten persons requested this quite a while ago (I need
to start noting names on todo items...) when it was quite hard to
implement. Now it is easy and I don't see it can do any harm, so hey presto...

036de0c5e4 Instead of just checking for an empty buffer, which may not be the case if 
there is unconsumed data, save the previous size and use it instead. This means
that activity monitoring should work in this (unlikely) event.

Also remove a debugging statement that no longer seems necessary.

06ddd3dcf8 Add a flags member to the grid_line struct and use it to differentiate lines 
wrapped at the screen edge from those terminated by a newline. Then use this
when copying to combine wrapped lines together into one.

04e97e8aef Using the alternative screen (smcup/rmcup) should also preserve the current 
colours and attributes. Found thanks to a report from Taylor Venable.

While here also nuke a couple of extra blank lines.

76a9d98562 Make some functions which return unused values void (mostly found by lint) and 
tweak a redundant expression in window_pane_set_mode.

359285928b 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.

f031975dc0 Implement the CBT (backward tab) sequence (\033[Z). 2009-06-04 21:02:21 +00:00
Nicholas Marriott
d42fb43f4f Proper support for tab stops (\033H etc), using a bitstring(3). Makes another 
vttest test happy.

Nicholas Marriott
d6015824dd 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.
 2009-06-04 14:42:14 +00:00
Nicholas Marriott
6c1f03578d Oops, CAN and SUB should abort the sequence (return to first state), not remain 
in the same state.
 2009-06-04 14:24:49 +00:00
Nicholas Marriott
8dd2f0da3f 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.

52ec9b9ec4 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.

2faec76afa 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.

Suggested by deraadt a few days ago.

35876eaab9 Import tmux, a terminal multiplexor allowing (among other things) a single 
terminal to be switched between several different windows and programs
displayed on one terminal be detached from one terminal and moved to another.
