67b4d5b609 Support the latest theory for mouse input, this is enabled/disabled with 
SM/RM 1006 and is similar in style to SGR input: \033[<b;x;yM or
\033[b;x;ym. From Egmont Koblinger.

d4785fe798 Don't set key KEYC_NONE on xterm_keys_find match() 
When calling xterm_keys_find(); if we get a complete match, don't set
the key to unknown before calling the action to complete the binding;
otherwise non-prefixed bindings will not work.

d210d99cce Make mouse event structure clearer by defining events (up, click, drag) 
and simplifying how buttons and wheels are represented, from Ailin
Nemui. Should be no functional changes.

7c9d003e99 Some terminals respond to secondary DA with primary (they ignore the 
intermediate character). So ignore the possible responses to primary DA.

d8805af66b On xterm 271 and later, put the terminal into SCL 5 and use DECCRA for 
scrolling the region in panes (if the large region check isn't
hit). With help from Ailin Nemui.

d5ed5fb08f Two fixes by Micah Cowan: make mouse work properly beyond >127 on signed 
char architectures and properly parse $TMUX by stopping the socket path
at the first comma.

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.

43fa9a9ba6 When the mode-mouse option is on, support dragging to make a selection 
in copy mode.

Also support the scroll wheel, although xterm strangely does not ignore
it in application mouse mode, causing redraw artifacts when scrolling up
(other terminals appear to be better behaved).

19ea306606 Allow keys to be replaced and reorder the table so that terminfo-defined keys

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...

f27fefd7b8 Look for mice and xterm keys before standard function keys as they are less 
likely to be partial versions.

d9deb4b530 Support rxvt-style keys again, but this time: support all the variations, put 
them in as raw escape sequences rather than fiddling with the values from
terminfo, put them /after/ the terminfo values so the latter take precedence.

05831b52c4 Twiddling the last bit is an rxvtism, so do not support it in the table by

80e0158112 Switch the tty key tree over to an (unbalanced) ternary tree which allows 
partial matches to be done (they wait for further data or a timer to expire,
like a naked escape).

Mouse and xterm-style keys still expect to be atomic.
 2009-11-05 19:29:41 +00:00

a790e16fa2 Key flags are only used for initialisation so they are not needed in the main 
tty_key struct.

b58bf49e91 Switch tty key input over to happen on a read event. This is a bit more 
complicated because of escape input, but in that case instead of processing a
key immediately, schedule a timer and reprocess the bufer when it expires.

This currently assumes that keys will be atomic (ie that if eg F1 is pressed
the entire sequence is present in the buffer). This is usually but not always
true, a change in the tree format so it can differentiate potential (partial)
key sequences will happens soon and will allow this to be fixed.

e831649b64 Not all terminals swap CSI and SS3 on ctrl, so remove that. 
Also mark the rxvt special-cases as such until terminfo is updated to have
kLFT5, kRIT5 etc.

fd2ef18a70 Rewrite xterm-keys code (both input and output) so that works (doesn't always 
output the same modifiers, accepts all the possible input keys) and is more
understandable.

c92c2bfb10 Support the (mostly new) function key+modifier caps (kIC-kIC7). Most of these 
will be caught (soon) by the xterm keys code in xterm itself but some other
descriptions such as rxvt define them as well.
 2009-10-26 16:00:51 +00:00

d0aa883e07 As we always put the cursor keys into application mode, assume keys sent 
with CSI have ctrl.

Also add a couple of comments.

4bc0f6e7e9 Clean up by introducing a wrapper struct for mouse clicks rather than passing 
three u_chars around.

As a side-effect this fixes incorrectly rejecting high cursor positions
(because it was comparing them as signed char), reported by Tom Doherty.

639fbe0392 Detect backspace by looking at termios VERASE and translate it into \177 (which 
matches screen's behaviour if not its termcap/terminfo entry). The terminfo kbs
cap is often wrong or missing so it can't be used, and just assuming \177 may
be wrong.
