Unused variable.

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.
|
| |
|
|
|
|
|
| |
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@.

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.

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.

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.

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.
|
| |
|
|
|

Always move the cursor position on !xenl terminals, since there is no invisible
last cursor position.
Also nuke an unused variable.
|
| |
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
|
| |
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.
|
| |
|
|
|
| |
Don't try to use \n across scroll region when doing \r\n either.
|
| |
|
|
|
|
| |
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 :-/.
|

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.

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.
|
| |
|
|
|
|
| |
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.
|
| |
|
|
|
|
| |
Use absolute movement if right at the end of the line as it isn't a reliable
place to move from relatively.
|
| |
|
|
|
|
|
| |
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%).
|
| |
|
|
|
| |
Similarly add a tty_cursor_pane function to tidy up most of the calls.
|
| |
|
|
|
| |
_absolute is redundant, just use tty_region.
|
| |
|
|
|
|
| |
Cleanup: use two functions for region setting, one for absolute and one inside
pane.
|
| |
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
| |
There is no point setting the scroll region up for line feeds unless scrolling
is actually going to happen, so don't.
|
| |
|
|
|
|

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.

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.
|

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.
|
| |
|
|
|
|
| |
Don't die if the client is detaching (the tty has been closed) after waking up
from locking.
|
| |
|
|
|
|
|
|
|
|
|
|
|
|
|
|

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.
|
| |
|
|
|
|
|
|
|

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.
|

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.
|
| |
|
|

Be more careful about what flags are cleared when opening the terminal,
otherwise the opened/started flags are cleared and the terminal never released.
|
| |
|
|
|
|
| |
Permit options such as status-bg to be configured using the entire 256 colour
palette by setting "colour0" to "colour255".
|
| |
|
|
|
|
|
| |
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.
|
| |
|
|
|
| |
Emulate dch/dch1 if missing by redrawing the entire line.
|

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.

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.
|
| |
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
|
|
|
|
|
| |
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.
|
| |
|
|
|
| |
Add a TTY_OPENED flag and tidy a little.
|
| |
|
|
|
|
| |
Drop the no_stop argument to tty_close and tty_free in favour of a flag in the
tty struct.

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 contains 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.

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.

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).
|
| |
|
|
|
| |
Draw UTF-8 characters under the selection correctly.
|
| |
|
|

tty_write is relatively short and the only function left in tty-write.c so
move it into tty.c.
|
| |
|
|
|
|
| |
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.
|
| |
|
|
|
|
|
| |
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.
|
| |
|
|
|
|
| |
There are relatively few arguments to tty_cmd_* functions now, so tidy them up
by using a struct rather than hiding everything with varargs.
|
| |
|
|
|
|
| |
tty_cmd_raw is only used once, for raw UTF-8 output, so rename it to
tty_cmd_utf8character and eliminate the size argument.
|
| |
|
|
|
|

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.
