colours).

796eb522ac vte is buggy and doesn't home the cursor after changing the scroll
region. Several people are hitting this, so add a workaround.

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...

d31d4c05cf Emulate il1, dl1, ich1 to run (albeit slowly) with vt100 feature set. 2009-11-26 14:46:08 +00:00

a78cc98c8b Cleanup by moving various (mostly horrible) little bits handling UTF-8 grid
data into functions in a new file, grid-utf8.c, and use sizeof intead of
UTF8_DATA.

Also nuke trailing whitespace from tmux.1, reminded by jmc.

5ae542e7ee Emulate the ri (reverse index) capability: this allows tmux to at least start
on Sun consoles (TERM=sun or sun-color), even if there appear to still be
problems on some boxes (my Blade 100 is fine but edd's Blade 1000 shows odd
screen corruption).

6609093625 Just ignore tty fd errors rather than dying, stops the server dying if the
session is disconnected abrubtly (eg ssh ~.).

bed8153ba0 Clear to the end of the screen from the right starting point when drawing

Terbeck.

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.

a94535f318 Fix the reverse emulation when a terminal doesn't have setab to use the correct
fg/bg (adjusted if spaces) and happen before attribute setting.

1eaefbf169 Add a minor optimisatin: if the character being printed is space, don't worry
about setting the background colour or attributes (except reverse).

5730cbf3e3 Twaek this slightly to avoid confusing use of flags variable. 2009-10-28 08:33:20 +00:00

eb5f4460d1 Setting SGR0 when setting the fg and bg has problems if only one of the two is
meant to be default, so rewrite the code to move this outside, move setting
colours before attributes and generally clean up.

Tested by sthen@, fixes problems he was seeing with mutt and should fix some
existing problems with (rarely) lost attributes.

3a7636ff0f Remove the -d flag to tmux and just use op/AX to detect default colours.
Irritatingly, although op can be used to tell if a terminal supports default
colours, it can't be used to set them because in some terminfo descriptions it
resets attributes as a side-effect (acts as sgr0) and in others it doesn't, so
it is not possible to determine reliably what the terminal state will be
afterwards. So if AX is missing and op is present, tmux just sends sgr0.

Anyone using -d for a terminal who finds they actually needed it can replace it
using terminal-overrides, but please let me know as it is probably an omission
from terminfo.

dd46f634fe Now we are correctly not redrawing the whole pane on linefeed, redo the
last-cursor-position code to move to the right position when panes reach EOL.

9b5da97e6f Don't redraw the scroll region on linefeed/reverse index unless it is necessary
(the cursor is at the bottom/top). Should fix slow cursor movement when using
vi in a pane spotted by pirofti@.

683ddbc466 Some terminals don't correctly clear their let's-wrap flag after changing the
scroll region (which moves the cursor to 0,0). This means that if the cursor
was at the edge of the screen, any further output after scroll region change
incorrectly causes a line wrap. Add a workaround to move the cursor to position
0 if it is at the screen edge before changing scroll region.

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.

62f234ce3b UTF-8 combined character fixes.
Thai can have treble combinations (1 x width=1 then 2 x width=0) so bump the
UTF-8 cell data size to 9 and alter the code to allow this.

Also break off the combining code into a separate function, handle any further
combining beyond the buffer size by replacing the character with _s, and when
redrawing the UTF-8 character don't assume the first part has just been
printed, redraw the entire line.

387f4d42cc Move the check for whether to force a line wrapper lower down into the tty code
where it has access to the tty width, which is what should have been checked.

daa26079ee Always move the cursor position on !xenl terminals, since there is no invisible
last cursor position.

Also nuke an unused variable.

43d62c1ae3 Instead of having a complicated check to see if the cursor is in the last
position to avoid an explicit wrap, actually move it there.

Some UTF-8 fixes to come.

70355021d8 When checking whether the region will scroll and the cursor position is thus
unsuitable for using CUD/CUU, check the current cursor position not the target
position.

5d78371628 Don't try to use \n across scroll region when doing \r\n either. 2009-10-13 08:37:15 +00:00

4dcb5040a0 Instead of using something sort of similar for both newline checks, use
something the same. Doesn't fix the bug I'm looking for though :-/.

d7626cd9d7 When drawing lines that have wrapped naturally, don't force a newline but
permit them to wrap naturally again. This allows terminals that use this to
guess where lines start and end for eg mouse selecting (like xterm) to work
correctly.

This was another long-standing issue raised by several people over the last
while.

Thanks to martynas@ for much testing. This was not trivial to get right so
bringing it in for wider testing and adn to fix any further glitches in-tree.

693b3d03e6 Don't run through the column unchanged case if the row was unchanged but there
were no suitable optimisations, instead make it an else to fall through to
absolute addressing.

eb9826f65d If the vertical cursor movement crosses the scroll region, CUU and CUD
shouldn't be used even if VPA isn't present - in that case CUP should be used.
2009-10-12 16:37:43 +00:00
Nicholas Marriott
0aab5811ca Use absolute movement if right at the end of the line as it isn't a reliable
place to move from relatively.
2009-10-12 14:54:19 +00:00
Nicholas Marriott
687c4a9fab Use relative cursor movement instead of absolute when possible and when
supported by the terminal to reduce the size of the output data (generally
about 10-20%).

pane.

0a2a354499 Like linefeed, don't set the scroll region for reverse index unless it will be
needed.

While here, also tidy up a couple of long lines and remove an extraneous blank.

3a20a05a49 There is no point setting the scroll region up for line feeds unless scrolling
is actually going to happen, so don't.

bf38a311da The UTF-8 detection idea doesn't work and I am reasonably happy with the
current methods, so remove the (already #ifdef 0'd) code.

d528184836 Be less aggressive about turning the cursor off, only explicitly turn it off
when tmux is redrawing, otherwise leave in the state set by the application.

9200a0be7a Support -c like sh(1) to execute a command, useful when tmux is a login
shell. Suggested by halex@.

This includes another protocol version increase (the last for now) so again
restart the tmux server before upgrading.
