Instead of bailing out on the first configuration file error, carry on,
collecting all the errors, then start with the active window in more mode
displaying them.
Add "server options" which are server-wide and not bound to a session or
window. Set and displayed with "set -s" and "show -s".
Currently the only option is "quiet" (like command-line -q, allowing it to be
set from .tmux.conf), but others will come along.
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...
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.
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.
Initial changes to move tmux to libevent.
This moves the client-side loops are pretty much fully over to event-based only
(tmux.c and client.c) but server-side (server.c and friends) treats libevent as
a sort of clever poll, waking up after every event to run various things.
Moving the server stuff over to bufferevents and timers and so on will come
later.
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.
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.
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.
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.
When using tmux as a login shell, there is currently no way to specify a shell
to be used as a login shell inside tmux, so add a default-shell session option.
This sets the shell invoked as a login shell when the default-command option is
empty.
The default option value is whichever of $SHELL, getpwuid(getuid())'s pw_shell
or /bin/sh is valid first.
Based on a diff from martynas@, changed by me to be a session option rather
than a window option.
Use "Password:" with no space for password prompts and don't display a *s for
the password, like pretty much everything else. From martynas@ with minor
tweaks by me.
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.
Add some other obvious variables to update-environment (WINDOWID SSH_ASKPASS
SSH_AUTH_SOCK SSH_AGENT_PID SSH_CONNECTION) so they are updated in the session
environment on new/attach.
Switch tmux to use imsg. This is the last major change to make the
client-server protocol more resilient and make the protocol versioning work
properly. In future, the only things requiring a protocol version bump will be
changes in the message structs, and (when both client and server have this
change) mixing different versions should nicely report an error message.
As a side effect this also makes the code tidier, fixes a problem with the way
errors reported during server startup were handled, and supports fd passing
(which will be used in future).
Looked over by eric@, thanks.
Please note that mixing a client with this change with an older server or vice
versa may cause tmux to crash or hang - tmux should be completely exited before
upgrading.
Infrastructure and commands to manage the environment for processes started
within tmux.
There is a global environment, copied from the external environment when the
server is started and each session has an (initially empty) session
environment which overrides it.
New commands set-environment and show-environment manipulate or display the
environments.
A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.
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).
