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.
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 choose-client command and extend choose-{session,window} to accept a
template. After a choice is made, %% (or %1) in the template is replaced by the
name of the session, window or client suitable for -t and the result executed
as a command. So, for example, "choose-window "killw -t '%%'"" will kill the
selected window.
The defaults if no template is given are (as now) select-window for
choose-window, switch-client for choose-session, and detach-client for
choose-client (now bound to D).
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.
Extend command-prompt with a -p option which is a comma-separated list of one
or more prompts to present in order.
The responses to the prompt are replaced in the template string: %% are
replaced in order, so the first prompt replaces the first %%, the second
replaces the second, and so on. In addition, %1 up to %9 are replaced with the
responses to the first the ninth prompts
The default template is "%1" so the response to the first prompt is processed
as a command.
Note that this changes the behaviour for %% so if there is only one prompt,
only the first %% will be replaced. Templates such as "neww -n '%%' 'ssh %%'"
should be changed to "neww -n '%1' 'ssh %1'".
From Tiago Cunha.
Now that pane targets (-t) are supported, switch some commands to use them
where it makes sense: clock-mode, copy-mode, scroll-mode, send-keys,
send-prefix.
Add (naive) searching and goto line in copy mode. Searching is C-r and C-s with
emacs keys, / and ? with vi; n repeats the search again with either key
set. All searching wraps the top/bottom. Goto line is g for both emacs and vi.
The search prompts don't have full line editing, just simple append and delete
characters.
Also sort the mode keys list in tmux.1.
When creating a new session from the command-line where there is an external
terminal, copy the termios(4) special characters and use them for new windows
created in the new session. Suggested by Theo.
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 there is an error in the configuration file, don't just exit(1) as this can
cause the client to hang. Instead, send the error message, then mark the client
as bad and start a normal shutdown so the server exits once the error is
written.
This also allows some code duplicating daemon(3) to be trimmed and logging to
begin earlier.
Prompted by Theo noticing the behaviour on error wasn't documented.
Merge pane number into the target specification for pane commands. Instead of
using -p index, a target pane is now addressed with the normal -t window form
but suffixed with a period and a pane index, for example :0.2 or
mysess:mywin.1. An unadorned number such as -t 1 is tried as a pane index in
the current window, if that fails the same rules are followed as for a target
window and the current pane in that window used.
As a side-effect this now means that swap-pane can swap panes between
different windows.
Note that this changes the syntax of the break-pane, clear-history, kill-pane,
resize-pane, select-pane and swap-pane commands.
Next step towards customisable mode keys: build each default table of keys
into a named tree on start and use that for lookups. Also add command to string
translation tables and modify list-keys to show the mode key bindings (new
-t argument).
Permit commands to be bound to key presses without the prefix key first. The
new -n flag to bind-key and unbind-key sets or removes these bindings, and
list-key shows them in []s.
up-pane and down-pane no longer auto-repeat; update the description of
repeat-time accordingly. ok nicm@
if you prefer old behaviour;
bind -r Up up-pane
bind -r Down down-pane
Tidy the target parsing code a bit and correct the behaviour so that as before
a string with no colon as a target window is first looked up as a window then
as a session, noted by Iain Morgan.
Also attempt to clarify the description of the target specification in the man
page.
New options, window-status-current-{fg,bg,attr}, to set the fg, bg and
attributes with which the current window is shown in the status line. From
Johan Friis, thanks.
Each window now has a tree of layout cells associated with it. In this tree,
each node is either a horizontal or vertical cell containing a list of other
cells running from left-to-right or top-to-bottom, or a leaf cell which is
associated with a pane.
The major functional changes are:
- panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and
vertically (splitw -v, C-b ");
- panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D,
bound to C-b left/right/up/down and C-b M-left/right/up/down);
- layouts are now applied and then may be modified by resizing or splitting
panes, rather than being fixed and reapplied when the window is resized or
panes are added;
- manual-vertical layout is no longer necessary, and active-only layout is gone
(but may return in future);
- the main-pane layouts now reduce the size of the main pane to fit all panes
if possible.
Thanks to all who tested.
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.
status line (bound to "i" by default).
- Add support for including the window index, pane index, and window name
in status-left, or status-right.
- Bump protocol version.
- move the code back into cmd.c and merge with the existing functions where
possible;
- accept "-tttyp0" as well as "-t/dev/ttyp0" for clients;
- when looking up session names, try an exact match first, and if that fails
look for it as an fnmatch pattern and then as the start of a name - if more
that one session matches an error is given; so if there is one session called
"mysession", -tmysession, -tmysess, -tmysess* are equivalent but if there
is also "mysession2", the last two are errors;
- similarly for windows, if the argument is not a valid index or exact window
name match, try it against the window names as an fnmatch pattern and a
prefix.
and makes emacs happy when pasting into some modes. A new -r (raw) flag to
paste-buffer pastes without the translation.
From Kalle Olavi Niemitalo, thanks!
argument if the shell command in the first succeeds, for example:
if "[ -e ~/.tmux.conf.alt ]" "source .tmux.conf.alt"
Written by Tiago Cunha, many thanks.
highlight the status line if it matches.
- To make this possible, the function cmd_find_window_search from
cmd-find-window.c had to be moved to window.c and renamed window_pane_search.
- While there use three new functions in server.c to check for bell, activity,
and content, to avoid too much nesting.
