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...
Eliminate duplicate code and ease the passage for server-wide options by adding
a -w flag to set-option and show-options and making setw and showw aliases to
set -w and show -w.
Note: setw and showw are still there, but now aliases for set -w and show -w.
Add a -p flag to display-message to print the output rather than displaying in
the status line, this allows things like "display -p '#W'" to find the current
window index.
Two new options, window-status-format and window-status-current-format, which
allow the format of each window in the status line window list to be controlled
using similar # sequences as status-left/right.
This diff also moves part of the way towards UTF-8 support in window names but
it isn't quite there yet.
Revert to xterm-keys off by default. It was on as an experiment to see if the
option could be removed, but it affects vi, so we have to keep the option, and
a conservative default is better.
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.
Add a per-client log of status line messages displayed while that client
exists. A new message-limit session option sets the maximum number of entries
and a command, show-messages, shows the log (bound to ~ by default).
This (and prompt history) might be better as a single global log but until
there are global options it is easier for them to be per client.
There is no real standard for modifier plus function keys. Previously, tmux
output some from rxvt but in other ways did the same as xterm or other
terminals, but this is a bit inconsistent.
xterm's method is fairly sensible and we already support it (xterm-keys), so
enable it by default instead.
Add an activity time for clients, like for sessions, and change session and
client lookup to pick the most recently used rather than the most recently
created - this is much more useful when used interactively and (because the
activity time is set at creation) should have no effect on source-file.
Based on a problem reported by Jan Johansson.
[ is a punctuation character and should be escaped with Ql. Although the
current groff version we have seems to handle it fine, other versions are not
so tolerant.
Add mode keys to move the cursor to the top, middle and bottom of the screen.
H/M/L in vi mode and M-R/M-r in emacs (bottom of screen not bound in emacs).
Add a pipe-pane command to allow a pane to be piped to a shell command, for
example:
pipe-pane 'cat >~/out'
No arguments stops outputing and closes the pipe; the -o flag toggles a pipe
and on and off (useful for key bindings).
Suggested by espie@.
Rather than running status-left, status-right and window title #() with popen
immediately every redraw, queue them up and run them in the background,
starting each once every status-interval. The actual status line uses the
output from the last run.
This brings several advantages:
- tmux itself may be called from inside #() without causing the server to hang;
- likewise, sleep or similar doesn't cause the server to block;
- commands aren't run excessively often when redrawing;
- commands shared by status-left and status-right, or used multiple times, will
only be run once.
run-shell and if-shell still use system()/popen() but will be changed over to
use this too later.
New option, mouse-select-pane. If on, the mouse may be used to select the
current pane.
Suggested by sthen@ and also by someone else ages ago who I have forgotten.
Add "grouped sessions" which have independent name, options, current window and
so on but where the linked windows are synchronized (ie creating, killing
windows and so on are mirrored between the sessions). A grouped session may be
created by passing -t to new-session.
Had this around for a while, tested by a couple of people.
Support for individual session idle time locking. May be enabled by turning off
the lock-server option (it is on by default). When this is off, each session
locks when it has been idle for the lock-after-time setting. When on, the
entire server locks when ALL sessions have been idle for their individual
lock-after-time settings.
This replaces one global-only option (lock-after-time) with another
(lock-server), but the default behaviour is usually preferable so there don't
seem to be many alternatives.
Diff/idea largely from Thomas Adam, tweaked by me.
Add a simple synchronize-panes window option: when set, all input to any pane
that is part of the window is also sent to all other panes in the same
window. Suggested by several, most recently Tomasz Pajor.
Make C-Up and C-Down in copy mode scroll the screen up and down one line
without moving the cursor, like Up and Down in scroll mode (which will shortly
disappear).
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.
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.
Permit multiple prefix keys to be defined, separated by commas, for example:
set -g prefix ^a,^b
Any key in the list acts as the prefix. The send-prefix command always sends
the first key in the list.
New option, set-titles-string, to allow the window title to be specified (as
for status-left/right) if set-titles is on. Also only update the title when the
status line is being redrawn.
