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).

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

4dcb5040a0 Instead of using something sort of similar for both newline checks, use

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.

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%).

3a20a05a49 There is no point setting the scroll region up for line feeds unless scrolling

bf38a311da The UTF-8 detection idea doesn't work and I am reasonably happy with the

d528184836 Be less aggressive about turning the cursor off, only explicitly turn it off

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.

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.

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.

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

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.

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.

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

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