Two new options:
- server option "exit-unattached" makes the server exit when no clients
are attached, even if sessions are present;
- session option "destroy-unattached" destroys a session once no clients
are attached to it.
These are useful for preventing tmux remaining in the background where
it is undesirable and when using tmux as a login shell to keep a limit
on new sessions.
|
|
Reset running jobs when the status line is enabled or disabled as well,
some people have it bound to a key.
|
|
New option, detach-on-destroy, to set what happens to a client when the session
it is attached to is destroyed. If on (the default), it is detached; if off, it
is switched to the most recently active session.

Colour+attribute options for status line alerts, from Alex Alexander.
|
|
Option to set the characters considered word separators in copy mode, from
Micah Cowan.
|
|
Add an option to disable the smcup/rmcup alternate screen behaviour inside
tmux. From clemens fischer.
|
|
Option to display the active pane in a different colour with the display-panes
command. From Paul Hoffman, thanks.
|
|
Options to set the colour of the pane borders, with different colours for the
active pane.
|
|
New server option, escape-time, to set the timeout used to detect if escapes
are alone or part of a function key or meta sequence.
|
|
Use quiet variable, and add missing sentinel to options array.
|
|
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...
|
|
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 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.
|
|
Get rid of the ugly CMD_CHFLAG macro and use a const string (eg "dDU") in the
command entry structs and a couple of functions to check/set the flags.
|
|
Add a flag for jobs that shouldn't be freed after they've died and use it for
status jobs, then only kill those jobs when status-left, status-right or
set-titles-string is changed.
Fixes problems with changing options from inside #().
|
|
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.
|

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.
|
|
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.
|
|
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 a base-index session option to specify the first index checked when looking
for an index for a new window.
|
|
Add flags for 1+2 and 2 arguments to the generic target code, use it for
cmd-set-environment/option/window-option and remove the generic options
parsing.
|
|
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.
|
|
Options to set the colours and attributes for status-left/-right. From Thomas
Adam, thanks.
|
|
Add a -a flag to set-option and set-window-option to append to an existing
string value, useful for terminal-overrides.
|
|
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).
|
|
Make all messages sent between the client and server fixed size.
This is the first of two changes to make the protocol more resilient and less
sensitive to other changes in the code, particularly with commands. The client
now packs argv into a buffer and sends it to the server for parsing, rather
than doing it itself and sending the parsed command data.
As a side-effect this also removes a lot of now-unused command marshalling
code.
Mixing a server without this change and a client with or vice versa will cause
tmux to hang or crash, please ensure that tmux is entirely killed before
upgrading.
|
|
Add a status-justify option to allow the window list in the status line to be
positioned at the left, centre, or right.
|
|
If these are enabled (and the monitor-activity, bell-action and monitor-content
options are configurated appropriately), when activity, a bell, or content is
detected, a message is shown.
Also tidy up the bell/activity/content code in server.c slightly and fix a
couple of errors.
|
|
annoying and it is only use for iterating, so use a sentinel to mark the end of
each array instead. Different fix for a problem pointed out by Kalle Olavi
Niemitalo.
|
|
maintain and is only going to get worse as more are used. So instead, add a new
uint64_t member to cmd_entry which is a bitmask of upper and lowercase options
accepted by the command.
This means new single character options can be used without the need to add it
explicitly to the list.

clear. No functional change, getting this out of the way to make later options
changes easier.

characters in status-left and status-right (if on, they are treated as UTF-8;
otherwise passed through).
|
|
windows created in that session (like "remain-by-default" used to do). Not perfectly happy about this, but until I can think of a good way to introduce it generically (maybe a set of options in the session) this will do. Fixes SF request 2527847.

options: status-attr, mode-attr, message-attr. A comma-separataed list is accepted containing: bright, dim, underscore, blink, reverse, hidden, italics, for example: set -g status-attr bright,blink
From Josh Elsasser, thanks!

command line.

defaults to 500 ms. However, it only applies to a small subset of commands, currently: up-pane, down-pane, next-window, previous-window, resize-pane-up, resize-pane-down. These are the commands for which it is obviously useful, having it for everything else was just bloody annoying.
