2009-11-09Just ignore tty fd errors rather than dying, stops the server dying if theNicholas Marriott
session is disconnected abrubtly (eg ssh ~.).
2009-11-05Clear to the end of the screen from the right starting point when drawingNicholas Marriott
line-by-line (in panes or if ed not supported). Fixes problem spotted by Frank Terbeck.
2009-11-05Switch tty key input over to happen on a read event. This is a bit moreNicholas Marriott
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.
2009-11-04Switch tty fds over to a bufferevent.Nicholas Marriott
2009-11-04Ignore the colour on space, /not/ the attributes.Nicholas Marriott
2009-11-04Fix the reverse emulation when a terminal doesn't have setab to use the correctNicholas Marriott
fg/bg (adjusted if spaces) and happen before attribute setting.
2009-10-28Add a minor optimisatin: if the character being printed is space, don't worryNicholas Marriott
about setting the background colour or attributes (except reverse).
2009-10-28Twaek this slightly to avoid confusing use of flags variable.Nicholas Marriott
2009-10-28Setting SGR0 when setting the fg and bg has problems if only one of the two isNicholas Marriott
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.
2009-10-26tabs are better; ok nicmTheo de Raadt
2009-10-25Remove the -d flag to tmux and just use op/AX to detect default colours.Nicholas Marriott
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.
2009-10-21Unused variable.Nicholas Marriott
2009-10-21Now we are correctly not redrawing the whole pane on linefeed, redo theNicholas Marriott
last-cursor-position code to move to the right position when panes reach EOL.
2009-10-21Don't redraw the scroll region on linefeed/reverse index unless it is necessaryNicholas Marriott
(the cursor is at the bottom/top). Should fix slow cursor movement when using vi in a pane spotted by pirofti@.
2009-10-21Some terminals don't correctly clear their let's-wrap flag after changing theNicholas Marriott
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.
2009-10-20Try to reduce the UTF-8 mess.Nicholas Marriott
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.
2009-10-20UTF-8 combined character fixes.Nicholas Marriott
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.
2009-10-20Move the check for whether to force a line wrapper lower down into the tty codeNicholas Marriott
where it has access to the tty width, which is what should have been checked.
2009-10-17Always move the cursor position on !xenl terminals, since there is no invisibleNicholas Marriott
last cursor position. Also nuke an unused variable.
2009-10-17Instead of having a complicated check to see if the cursor is in the lastNicholas Marriott
position to avoid an explicit wrap, actually move it there. Some UTF-8 fixes to come.
2009-10-16When checking whether the region will scroll and the cursor position is thusNicholas Marriott
unsuitable for using CUD/CUU, check the current cursor position not the target position.
2009-10-13Don't try to use \n across scroll region when doing \r\n either.Nicholas Marriott
2009-10-13Instead of using something sort of similar for both newline checks, useNicholas Marriott
something the same. Doesn't fix the bug I'm looking for though :-/.
2009-10-12When drawing lines that have wrapped naturally, don't force a newline butNicholas Marriott
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.
2009-10-12Don't run through the column unchanged case if the row was unchanged but thereNicholas Marriott
were no suitable optimisations, instead make it an else to fall through to absolute addressing.
2009-10-12If the vertical cursor movement crosses the scroll region, CUU and CUDNicholas Marriott
shouldn't be used even if VPA isn't present - in that case CUP should be used.
2009-10-12Use absolute movement if right at the end of the line as it isn't a reliableNicholas Marriott
place to move from relatively.
2009-10-12Use relative cursor movement instead of absolute when possible and whenNicholas Marriott
supported by the terminal to reduce the size of the output data (generally about 10-20%).
2009-10-12Similarly add a tty_cursor_pane function to tidy up most of the calls.Nicholas Marriott
2009-10-12_absolute is redundant, just use tty_region.Nicholas Marriott
2009-10-12Cleanup: use two functions for region setting, one for absolute and one insideNicholas Marriott
pane.
2009-10-11Like linefeed, don't set the scroll region for reverse index unless it will beNicholas Marriott
needed. While here, also tidy up a couple of long lines and remove an extraneous blank.
2009-10-10There is no point setting the scroll region up for line feeds unless scrollingNicholas Marriott
is actually going to happen, so don't.
2009-10-09The UTF-8 detection idea doesn't work and I am reasonably happy with theNicholas Marriott
current methods, so remove the (already #ifdef 0'd) code.
2009-10-09Be less aggressive about turning the cursor off, only explicitly turn it offNicholas Marriott
when tmux is redrawing, otherwise leave in the state set by the application.
2009-09-23Support -c like sh(1) to execute a command, useful when tmux is a loginNicholas Marriott
shell. Suggested by halex@. This includes another protocol version increase (the last for now) so again restart the tmux server before upgrading.
2009-09-23Don't die if the client is detaching (the tty has been closed) after waking upNicholas Marriott
from locking.
2009-09-23Remove the internal tmux locking and instead detach each client and run theNicholas Marriott
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.
2009-09-23Trim some code by moving the ioctl(TIOCGWINSZ) after SIGWINCH from the clientNicholas Marriott
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.
2009-09-23Don't attempt to open() the tty path, rely on the client sending its stdin fdNicholas Marriott
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.
2009-09-22Be more careful about what flags are cleared when opening the terminal,Nicholas Marriott
otherwise the opened/started flags are cleared and the terminal never released.
2009-09-10Permit options such as status-bg to be configured using the entire 256 colourNicholas Marriott
palette by setting "colour0" to "colour255".
2009-08-31Add a new display-panes command, with two options (display-panes-colour andNicholas Marriott
display-panes-time), which displays a visual indication of the number of each pane.
2009-08-21Emulate dch/dch1 if missing by redrawing the entire line.Nicholas Marriott
2009-08-14Send SGR0 when initialising the screen. Fixes problems on terminals with BCENicholas Marriott
(like putty) if the background colours is non-default when tmux starts. May also fix problems when resuming a suspended tmux.
2009-08-12A tty context must not be modified as it may be reused to update multipleNicholas Marriott
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.
2009-08-11Initialise log_fd to -1, prevents spurious disconnection of the client when itNicholas Marriott
ends up as fd 0 (likely if the server is started with "tmux start"). Also add some extra debugging messages to server.c.
2009-08-11Have the client pass its stdin fd to the server when identifying itself andNicholas Marriott
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.
2009-08-11Add a TTY_OPENED flag and tidy a little.Nicholas Marriott
2009-08-11Drop the no_stop argument to tty_close and tty_free in favour of a flag in theNicholas Marriott
tty struct.
