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
Nicholas Marriott
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

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%).

762459954f Similarly add a tty_cursor_pane function to tidy up most of the calls. 2009-10-12 09:29:58 +00:00

972a6f5656 _absolute is redundant, just use tty_region. 2009-10-12 09:16:59 +00:00

f05b32f7ad Cleanup: use two functions for region setting, one for absolute and one inside 
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.
 2009-10-11 22:35:10 +00:00
Nicholas Marriott
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.

631a618238 Don't die if the client is detaching (the tty has been closed) after waking up 
from locking.
 2009-09-23 07:25:31 +00:00
Nicholas Marriott
b01dcd7971 Remove the internal tmux locking and instead detach each client and run the 
command specified by a new option "lock-command" (by default "lock -np") in
each client.

This means each terminal has to be unlocked individually but simplifies the
code and allows the system password to be used to unlock.

Note that the set-password command is gone, so it will need to be removed from
configuration files, and the -U command line flag has been removed.

This is the third protocol version change so again it is best to stop the tmux
server before upgrading.
 2009-09-23 06:18:47 +00:00

962fa20b36 Trim some code by moving the ioctl(TIOCGWINSZ) after SIGWINCH from the client 
into the server.

This is another (the second of four) protocol version changes coming this
morning, so again the server should be killed before upgrading.
 2009-09-23 06:12:58 +00:00

64caf59e84 Don't attempt to open() the tty path, rely on the client sending its stdin fd 
with imsg and fatal if it doesn't, then set the FD_CLOEXEC flag in tty_init
instead of tty_open to prevent them leaking into child processes if any are
created between the two calls.

This bumps the protocol version, so the tmux server should be killed before
upgrading.

0a9005678d Be more careful about what flags are cleared when opening the terminal, 
otherwise the opened/started flags are cleared and the terminal never released.
 2009-09-22 19:11:52 +00:00

372a8cb1d9 Permit options such as status-bg to be configured using the entire 256 colour 
palette by setting "colour0" to "colour255".
 2009-09-10 17:16:24 +00:00
Nicholas Marriott
04319964b9 Add a new display-panes command, with two options (display-panes-colour and 
display-panes-time), which displays a visual indication of the number of each
pane.

5cf994856f Send SGR0 when initialising the screen. Fixes problems on terminals with BCE 
(like putty) if the background colours is non-default when tmux starts. May
also fix problems when resuming a suspended tmux.

bc497dbb92 A tty context must not be modified as it may be reused to update multiple 
clients, so make it const.

Also fix an actual modification which caused a hang when a session was
connected to multiple terminals at least one of which was missing ich/ich1.

e0a19abb99 Initialise log_fd to -1, prevents spurious disconnection of the client when it 
ends up as fd 0 (likely if the server is started with "tmux start").

Also add some extra debugging messages to server.c.
 2009-08-11 22:34:17 +00:00

4310282a4c Have the client pass its stdin fd to the server when identifying itself and 
have the server use that rather than reopening the tty. If the fd isn't given,
use the old behaviour (so no need for a version change).

This allows tmux to be used as the shell, so also change so that when working
out the command to execute if default-command is empty (the default), tmux will
try not execute itself.

4ec8ade11c Add a TTY_OPENED flag and tidy a little. 2009-08-11 20:29:04 +00:00
Nicholas Marriott
ff65e37545 Drop the no_stop argument to tty_close and tty_free in favour of a flag in the 
tty struct.

5e01b6d663 Change the way the grid is stored, previously it was: 
- a two-dimensional array of cells;
- a two-dimensional array of utf8 data;
- an array of line lengths.

Now it is a single array of a new struct grid_line each of which represents a
line and containts the length and an array of cells and an array of utf8 data.

This will make it easier to add additional per-line members, such as flags.

bcddddf98d If colours are not supported by the terminal, try to emulate a coloured 
background by setting or clearing the reverse attribute.

This makes a few applications which don't use the reverse attribute themselves
a little happier, and allows the status, message and mode options to have
default attributes and fg/bg options that work as expected when set as reverse.

1673735f02 Add a terminal-overrides session option allowing individual terminfo(5) entries 
to be overridden. The 88col/256col checks are now moved into the default
setting and out of the code.

Also remove a couple of old workarounds for xterm and rxvt which are no longer
necessary (tmux can emulate them if missing).

dd4a3b24fc tty_write is relatively short and the only function left in tty-write.c so move 
it into tty.c.
 2009-07-22 20:56:58 +00:00

ddad0be5f7 More tty code tidying: move the saved cursor/region position (from before the 
screen was updated) out of struct screen and into struct tty_ctx.

2ec2837daa enum tty_cmd is only used as an index into the array of command function 
pointers, so remove it and use the function pointers directly to represent
themselves.
 2009-07-22 18:02:23 +00:00
Nicholas Marriott
6a309c53a8 There are relatively few arguments to tty_cmd_* functions now, so tidy them up 
by using a struct rather than hiding everything with varargs.
 2009-07-22 16:45:31 +00:00

5bd72ec629 tty_cmd_raw is only used once, for raw UTF-8 output, so rename it to 
tty_cmd_utf8character and eliminate the size argument.

4a6d62e401 Don't send initialisation strings is1/2/3 (barely anything else does) and move 
smcup to the first and rmcup to the last sequences output to the terminal. This
allows tmux to use the alternate screen (smcup/rmcup) when available.

otherwise colour 8 isn't reset properly.

2de599ac0e Trying to predict the cursor position for UTF-8 output in the same way as for 
normal eight-bit output is wrong, separate it into a different function. Fixes
spacing when mixing UTF-8 with some escape sequences, notably the way w3m does
it.

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.

ebe07c2726 Fix some miscalculations when clearing to start of screen: the number of lines 
to the cursor is cy not cy - 1, and the current cursor cell should be included.

3f76a973ee Recent code to try and detect if a terminal supports UTF-8 by printing to it 
fails spectacularly on (at least) sparc64, so disable it for now. Thanks to
naddy and Josh Elsasser for help and testing.

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.
