CHANGES FROM 1.2 TO 1.3, 18 July 2010

* New input parser.

* Flags to move through panes -UDLR added to select-pane.

* Commands up-pane, and down-pane removed, since equivalent behaviour is now

available through the target flag (-t:+ and -t:-).

* Jump-forward/backward in copy move (based on vi's F, and f commands).

* Make paste-buffer accept a pane as a target.

* Flag -a added to new-window to insert a window after an existing one, moving

windows up if necessary.

* Merge more mode into copy mode.

* Run job commands explicitly in the global environment (which can be modified

with setenv -g), rather than with the environment tmux started with.

* Use the machine's hostname as the default title, instead of an empty string.

* Prevent double free if the window option remain-on-exit is set.

* Key string conversions rewritten.

* Mark zombie windows as dead in the choose-window list.

* Tiled layout added.

* Signal handling reworked.

* Reset SIGCHLD after fork to fix problems with some shells.

* Select-prompt command removed. Therefore, bound ' to command-prompt -p index

"select-window -t:%%" by default.

* Catch SIGHUP and terminate if running as a client, thus avoiding clients from

being left hanging around when, for instance, a SSH session is disconnected.

* Solaris 9 fixes (such as adding compat {get,set}env(3) code).

* Accept none instead of default for attributes.

* Window options window-status-alert-{alert,bg,fg} added.

* Flag -s added to the paste-buffer command to specify a custom separator.

* Allow dragging to make a selection in copy mode if the mode-mouse option is

set.

* Support the mouse scroll wheel.

* Make pipe-pane accept special character sequences (eg #I).

* Fix problems with window sizing when starting tmux from .xinitrc.

* Give tmux sockets (but not the containing folder) group permissions.

* Extend the target flags (ie -t) to accept an offset (for example -t:+2), and

make it wrap windows, and panes.

* New command choose-buffer added.

* New server option detach-on-destroy to set what happens to a client when the

session it is attached to is destroyed. If on (default), the client is

detached. Otherwise, the client is switched to the most recently active of

the remaining sessions.

* The commands load-buffer, and save-buffer now accept a dash (-) as the file

to read from stdin, or write to stdout.

* Custom layouts added.

* Additional code reduction, bug fixes, and manpage enhancements.

CHANGES FROM 1.1 TO 1.2, 10 March 2010

* Switch to libevent.

* Emulate the ri (reverse index) capability, ergo allowing tmux to at least

start on Sun consoles (TERM=sun, or sun-color).

* Assign each entry a number, or lowercase letter in choose mode, and accept

that as a shortcut key.

* Permit top-bit-set characters to be entered in the status line.

* Mark no-prefix keys with (no prefix), rather than [] in list-keys.

* New command show-messages (alias showmsgs), and new session option

message-limit, to show a per-client log of status lines messages up to the

number defined by message-limit.

* Do not interpret #() for display-message to avoid leaking commands.

* New window options window-status-format, and window-status-current-format to

control the format of each window in the status line.

* Add a -p flag to display-message to print the output, instead of displaying

it in the status line.

* Emulate il1, dl1, ich1 to run with vt100 feature set.

* New command capture-pane (alias capturep) to copy the entire pane contents

to a paste buffer.

* Avoid duplicating code by adding a -w flag to set-option, and show-options to

set, and show window options. The commands set-window-option, and

show-window-options are now aliases.

* Panes can now be referred to as top, bottom, top-left, etc.

* Add server-wide options, which can be set with set-option -s, and shown with

show-options -s.

* New server option quiet (like -q from the command line).

* New server option escape-time to set the timeout used to detect if escapes

are alone, part of a function key, or meta sequence.

* New session options pane-active-border-bg, pane-active-border-fg,

pane-border-bg, and pane-border-fg to set pane colours.

* Make split-window accept a pane target, instead of a window.

* New command join-pane (alias joinp) to split, and move an existing pane into

the space (the opposite of break-pane), thus simplifying calls to

split-window, followed by move-window.

* Permit S- prefix on keys for shift when the terminal/terminfo supports them.

* Window targets (-t flag) can now refer to the last window (!), next (+), and

previous (-) window by number.

* Mode keys to jump to the bottom/top of history, end of the next word, scroll

up/down, and reverse search in copy mode.

* New session option display-panes-active-colour to display the active pane in

a different colour with the display-panes command.

* Read the socket path from $TMUX if it's present, and -L, and -S are not

given.

* Vi-style mode keys B, W, and E to navigate between words in copy mode.

* Start in more mode when configuration file errors are detected.

* Rectangle copy support added.

* If attach-session was specified with the -r flag, make the client read-only.

* Per-window alternate-screen option.

* Make load-buffer work with FIFOs.

* New window option word-separators to set the characters considered as word

separators in copy mode.

* Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9]

in vi mode, or M-[1-9] in emacs mode.

* utf8 improvements.

* As usual, additional code reduction, bug fixes, and manpage enhancements.

CHANGES FROM 1.0 TO 1.1, 05 November 2009

* New run-shell (alias run) command to run an external command without a

window, capture it's stdout, and send it to output mode.

* Ability to define multiple prefix keys.

* Internal locking mechanism removed. Instead, detach each client and run the

external command specified in the new session option lock-command (by default

lock -np), thus allowing the system password to be used.

* set-password command, and -U command line flag removed per the above change.

* Add support for -c command line flag to execute a shell command.

* New lock-client (alias lockc), and lock-session (alias locks) commands to

lock a particular client, or all clients attached to a session.

* Support C-n/C-p/C-v/M-v with emacs keys in choice mode.

* Use : for goto line rather than g in vi mode.

* Try to guess which client to use when no target client was specified. Finds

the current session, and if only one client is present, use it. Otherwise,

return the most recently used client.

* Make C-Down/C-Up in copy mode scroll the screen down/up one line without

moving the cursor.

* Scroll mode superseded by copy mode.

* New synchronize-panes window option to send all input to all other panes in

the same window.

* New lock-server session option to lock, when off (on by default), each

session 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 setting.

* Add support for grouped sessions which have independent name, options,

current window, but where the linked windows are synchronized (ie creating,

killing windows are mirrored between the sessions). A grouped session may be

created by passing -t to new-session.

* New mouse-select-pane session option to select the current pane with the

mouse.

* Queue, and run commands in the background for if-shell, status-left,

status-right, and #() by starting each once every status-interval. Adds the

capability to call some programs which would previously cause the server to

hang (eg sleep/tmux). It also avoids running commands excessively (ie if used

multiple times, it will be run only once).

* When a window is zombified and automatic-rename is on, append [dead] to the

name.

* Split list-panes (alias lsp) off from list-windows.

* New pipe-pane (alias pipep) to redirect a pane output to an external command.

* Support for automatic-renames for Solaris.

* Permit attributes to be turned off in #[] by prefixing with no (eg nobright).

* Add H/M/L in vi mode, and M-R/M-r in emacs to move the cursor to the top,

middle, and bottom of the screen.

* -a option added to kill-pane to kill all except current pane.

* The -d command line flag is now gone (can be replaced by terminal-overrides).

Just use op/AX to detect default colours.

* input/tty/utf8 improvements.

* xterm-keys rewrite.

* Additional code reduction, and bug fixes.

CHANGES FROM 0.9 TO 1.0, 20 Sept 2009

* Option to alter the format of the window title set by tmux.

* Backoff for a while after multiple incorrect password attempts.

* Quick display of pane numbers (C-b q).

* Better choose-window, choose-session commands and a new choose-client command.

* Option to request multiple responses when using command-prompt.

* Improved environment handling.

* Combine wrapped lines when pasting.

* Option to override terminal settings (terminal-overrides).

* Use the full range of ACS characters for drawing pane separator lines.

* Customisable mode keys.

* Status line colour options, with embedded colours in status-left/right, and

an option to centre the window list.

* Much improved layouts, including both horizontal and vertical splitting.

* Optional visual bell, activity and content indications.

* Set the utf8 and status-utf8 options when the server is started with -u.

* display-message command to show a message in the status line, by default some

information about the current window.

* Improved current process detection on NetBSD.

* unlink-window -k is now the same as kill-window.

* attach-session now works from inside tmux.

* A system-wide configuration file, /etc/tmux.conf.

* A number of new commands in copy mode, including searching.

* Panes are now specified using the target (-t) notation.

* -t now accepts fnmatch(3) patterns and looks for prefixes.

* Translate \r into \n when pasting.

* Support for binding commands to keys without the prefix key

* Support for alternate screen (terminfo smcup/rmcup).

* Maintain data that goes off screen after reducing the window size, so it can

be restored when the size is increased again.

* New if-shell command to test a shell command before running a tmux command.

* tmux now works as the shell.

* Man page reorganisation.

* Many minor additions, much code tidying and several bug fixes.

CHANGES FROM 0.8 TO 0.9, 01 July 2009

* Major changes to build infrastructure: cleanup of makefiles and addition

of a configure script.

* monitor-content window option to monitor a window for a specific fnmatch(3)

pattern. The find-window command also now accepts fnmatch(3) patterns.

* previous-layout and select-layout commands, and a main-horizontal layout.

* Recreate the server socket on SIGUSR1.

* clear-history command.

* Use ACS line drawing characters for pane separator lines.

* UTF-8 improvements, and code to detect UTF-8 support by looking at

environment variables.

* The resize-pane-up and resize-pane-down commands are now merged together

into a new resize-pane command with -U and -D flags.

* confirm-before command to request a yes/no answer before executing dangerous

commands.

* Status line bug fixes, support for UTF-8 (status-utf8 option), and a key to

paste from the paste buffer.

* Support for some additional escape sequences and terminal features, including

better support for insert mode and tab stops.

* Improved window resizing behaviour, modelled after xterm.

* Some code reduction and a number of miscellaneous bug fixes.

================================================================================

On 01 June 2009, tmux was imported into the OpenBSD base system. From this date

onward changes are logged as part of the normal CVS commit message to either

OpenBSD or SourceForge CVS. This file will be updated to contain a summary of

major changes with each release, and to mention important configuration or

command syntax changes during development.

The list of older changes is below.

================================================================================

21 May 2009

* stat(2) files before trying to load them to avoid problems, for example

with "source-file /dev/zero".

19 May 2009

* Try to guess if the window is UTF-8 by outputting a three-byte UTF-8 wide

character and seeing how much the cursor moves. Currently tries to figure out

if this works by some stupid checks on the terminal, these need to be

rethought. Also might be better using a width 1 character rather than width 2.

* If LANG contains "UTF-8", assume the terminal supports UTF-8, on the grounds

that anyone who configures it probably wants UTF-8. Not certain if this is

a perfect idea but let's see if it causes any problems.

* New window option: monitor-content. Searches for a string in a window and if

it matches, highlight the status line.

18 May 2009

* main-horizontal layout and main-pane-height option to match vertical.

* New window option main-pane-width to set the width of the large left pane with

main-vertical (was left-vertical) layout.

* Lots of layout cleanup. manual layout is now manual-vertical.

16 May 2009

* select-layout command and a few default key bindings (M-0, M-1, M-2, M-9) to

select layouts.

* Recreate server socket on SIGUSR1, per SF feature request 2792533.

14 May 2009

* Keys in status line (p in vi mode, M-y in emacs) to paste the first line

of the upper paste buffer. Suggested by Dan Colish.

* clear-history command to clear a pane's history.

* Don't force wrapping with \n when asked, let the cursor code figure it out.

Should fix terminals which use this to detect line breaks.

* Major cleanup and restructuring of build infrastructure. Still separate files

for GNU and BSD make, but they are now hugely simplified at the expense of

adding a configure script which must be run before make. Now build and

install with:

$ ./configure && make && sudo make install

04 May 2009

* Use ACS line drawing characters for pane separator lines.

30 April 2009

* Support command sequences without a space before the semicolon, for example

"neww; neww" now works as well as "neww ; neww". "neww;neww" is still an

error.

* previous-layout command.

* Display the layout name in window lists.

* Merge resize-pane-up and resize-pane-down into resize-pane with -U and -D

flags.

29 April 2009

* Get rid of compat/vis.* - only one function was used which is easily

replaced,and less compat code == good.

27 April 2009

* Avoid using the prompt history when the server is locked, and prevent any

input entered from being added to the client's prompt history.

* New command, confirm-before (alias confirm), which asks for confirmation

before executing a command. Bound "&" and "x" by default to confirm-before

"kill-window" and confirm-before "kill-pane", respectively.

23 April 2009

* Support NEL, yet another way of making newline. Fixes the output from some

Gentoo packaging thing. Reported by someone on SF then logs that allowed a

fix sent by tcunha.

* Use the xenl terminfo flag to detect early-wrap terminals like the FreeBSD

console. Many thanks for a very informative email from Christian Weisgerber.

21 April 2009

* tmux 0.8 released.

17 April 2009

* Remove the right number of characters from the buffer when escape then

a cursor key (or other key prefixed by \033) is pressed. Reported by

Stuart Henderson.

03 April 2009

* rotate-window command. -U flag (default) for up, -D flag for down.

02 April 2009

* Change scroll/pane redraws to only redraw the single pane affected rather

than the entire window.

* If redrawing the region would mean redrawing > half the pane, just schedule

to redraw the entire window. Also add a flag to skip updating the window any

further if it is scheduled to be redrawn. This has the effect of batching

multiple redraws together.

01 April 2009

* Basic horizontal splitting and layout management. Still some redraw and other

issues - particularly, don't mix with manual pane resizing, be careful when

viewing from multiple clients and don't expect shell windows to redraw very

well after the layout is changed; generally cycling the layout a few times

will fix most problems. Getting this in for testing while I think about how

to deal with manual mode.

Split window as normal and cycle the layouts with C-b space. Some of the

layouts will work better when swap-pane comes along.

31 March 2009

* AIX port, thanks to cmihai for access to a box. Only tested on 6.1 with xlc

10.1 (make sure CC is set). Needs GNU make and probably ncurses (didn't try

plain curses). Also won't build with DEBUG, so comment the FDEBUG=1 line in

GNUmakefile.

* Draw a vertical line on the right when the window size is less than the

terminal size. This is partly to shake out any horizontal limit bugs on the

way to horizontal splitting/pane tiling. Currently a bit slow since it has to

do a lot of redrawing but hopefully that will improve as I get some better

ideas for how to do it.

* Fix remaining problems with copy and paste and UTF-8.

28 March 2009

* Better UTF-8 support, including combined characters. Unicode data is now

stored as UTF-8 in a separate array, the code does a lookup into this every

time it gets to a UTF-8 cell. Zero width characters are just appended onto

the UTF-8 data for the previous cell. This also means that almost no bytes

extra are wasted non-Unicode data (yay).

Still some oddities, such as copy mode skips over wide characters in a

strange way, and the code could do with some tidying.

* Key repeating is now a property of the key binding not of the command.

Repeat is turned on when the key is bound with the -r flag to bind-key.

next/previous-window no longer repeat by default as it turned out to annoy

me.

27 March 2009

* Clear using ED when redrawing the screen. I foolishly assumed using spaces

would be equivalent and terminals would pick up on this, but apparently not.

This fixes copy and paste in xterm/rxvt.

* Sockets in /tmp are now created in a subdirectory named, tmux-UID, eg

tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a

separate server, the new -L command line option should be used: this creates

a socket in the same directory with a different name ("-L main" will create

socket called "main"). -S should only be used to place the socket outside

/tmp. This makes sockets a little more secure and a bit more convenient to

use multiple servers.

21 March 2009

* New session flag "set-remain-on-exit" to set remain-on-exit flag for new

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.

07 March 2009

* Support for 88 colour terminals.

* break-pane command to create a new window using an existing pane.

02 March 2009

* Make escape key timer work properly so escape+key can be used without

lightning fast key presses.

13 February 2009

* Redo mode keys slightly more cleanly and apply them to command prompt

editing. vi or emacs mode is controlled by the session option status-keys.

12 February 2009

* Looking up argv[0] is expensive, so just use p_comm for the window name which

is good enough. Also increase name update time to 500 ms.

11 February 2009

* Only use ri when actually at the top of the screen; just move the cursor up

otherwise.

* FreeBSD's console wraps lines at $COLUMNS - 1 rather than $COLUMNS (the

cursor can never be beyond $COLUMNS - 1) and does not appear to support

changing this behaviour, or any of the obvious possibilities (turning off

right margin wrapping, insert mode). This is irritating, most notably because

it impossible to write to the very bottom-right of the screen without

scrolling. To work around this, if built on FreeBSD and run with a "cons"

$TERM, the bottom-right cell on the screen is omitted.

* Emulate scroll regions (slowly) to support the few terminals which don't have

it (some of which don't really have any excuse).

10 February 2009

* No longer redraw the status line every status-interval unless it has actually

changed.

08 February 2009

* Don't treat empty arguments ("") differently when parsing configuration

file/command prompt rather than command line.

* tmux 0.7 released.

03 February 2009

* New command, copy-buffer (alias copyb), to copy a session paste buffer to

another session.

01 February 2009

* The character pair #(command) may now contain (escaped) right parenthesis.

30 January 2009

* . now bound to "command-prompt 'move-window %%'" by default, from joshe.

29 January 2009

* Window options to set status line fg, bg and attributes for a single

window. Options are: window-status-fg, window-status-bg,

window-status-attr. Set to "default" to use the session status colours.

This allows quite neat things like:

$ cat ~/bin/xssh

#!/bin/sh

if [ ! -z "$TMUX" ]; then

case "$1" in

natalya)

tmux setw window-status-fg red >/dev/null

;;

natasha)

tmux setw window-status-fg yellow >/dev/null

;;

esac

fi

ssh "$@"

[ ! -z "$TMUX" ] && tmux setw -u window-status-fg >/dev/null

$ alias ssh="~/bin/xssh"

* Support #(command) in status-left, and status-right, which is displayed as

the first line of command's output (e.g. set -g status-right

"#(whoami)@#(hostname -s)"). Commands with )s aren't supported.

28 January 2009

* Support mouse in copy mode to move cursor. Can't do anything else at the

moment until other mouse modes are handled.

* Better support for at least the most common variant of mouse input: parse it

and adjust for different panes. Also support mouse in window/session choice

mode.

27 January 2009

* Bring back the fancy window titles with session/window names: it is easy to

work around problems with elinks (see FAQ).

* -u flag to scroll-mode and copy-mode to start scrolled one page

up. scroll-mode -u is bound to prefix,page-up (ppage) by default.

* Allow status, mode and message attributes to be changed by three new 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!

26 January 2009

* Be more clever about picking the right process to create the window name.

* Don't balls up the terminal on UTF-8 combined characters. Don't support them

properly either - they are just discarded for the moment.

25 January 2009

* load-buffer command

23 January 2009

* Use reverse colours rather than swapping fg and bg for message, mode and

status line. This makes these usable on black and white terminals.

* Better error messages when creating a session or window fails.

* Oops. Return non-zero on error. Reported by Will Maier.

21 January 2009

* Handle SIGTERM (and kill-server which uses it), a bit more neatly - tidy

up properly and print a nicer message. Same effect though :-).

* new-window now supports -k to kill target window if it exists.

* Bring back split-window -p and -l options to specify the height a percentage

or as a number of lines.

* Make window and session choice modes allow you to choose items in vi keys

mode (doh!). As a side-effect, this makes enter copy selection (as well

as C-w/M-w) when using emacs keys in copy mode. Reported by merdely.

20 January 2009

* Darwin support for automatic-rename from joshe; Darwin doesn't seem to have

a sane method of getting argv[0] and searching for the precise insane way

is too frustrating, so this just uses the executable name.

* Try to change the window title to match the command running it in. This is

done by reading argv[0] from the process group leader of the group that owns

the tty (tcgetpgrp()). This can't be done portably so some OS-dependent code

is introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment.

A new window flag, automatic-rename, is available: if this is set to off, the

window name is not changed. Specifying a name with the new-window,

new-session or rename-window commands will automatically set this flag to off

for the window in question. To disable it entirely set the option to off

globally (setw -g automatic-rename off).

19 January 2009

* Fix various stupid issues when the status line is turned off. Grr.

* Use reverse attributes for clock and cursor, otherwise they do not

appear on black and white terminals.

* An error in a command sequence now stops execution of that sequence.

Internally, each command code now passes a return code back rather than

talking to the calling client (if any) directly.

* attach-session now tries to start the server if it isn't already started - if

no sessions are created in .tmux.conf this will cause an error.

* Clean up starting server by making initial client get a special socketpair.

18 January 2009

* Unbreak UTF-8.

* -a flag to next-window and previous-window to select the next or previous

window with activity or bell. Bound to M-n and M-p.

* find-window command to search window names, titles and visible content (but

not history) for a string. If only one is found, the window is selected

otherwise a choice list is shown. This (as with the other choice commands)

only works from a key. Bound to "f" by default.

* Cleaned up command printing code, also enclose arguments with spaces in "s.

* Added command sequences. These are entered by separating each argument by a ;

argument (spaces on both sides), for example:

lsk ; lsc

To use a literal ; as the argument prefix it with \, for example:

bind x lsk \; lsc

Commands are executed from left to right. Also note that command sequences do

not support repeat-time repetition unless all commands making up the sequence

support it.

* suspend-client command to suspend a client. Don't try to background it

though...

* Mark attached sessions in sessions lists. Suggested by Simon Kuhnle.

17 January 2009

* tmux 0.6 released.

15 January 2009

* Support #H for hostname and #S for session name in status-left/right.

* Two new commands, choose-window and choose-session which work only when bound

to a key and allow the window or session to be selected from a list. These

are now bound to "w" and "s" instead of the list commands.

14 January 2009

* Rework the prefix-time stuff. The option is now called repeat-time and

defaults to 500 ms. 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.

* The alt-up and alt-down keys now resize a pane by five lines at a time.

* switch-pane is now select-pane and requires -p to select a pane. The

"o" key binding is changed to down-pane.

* up-pane and down-pane commands, bound to arrow up and down by default.

* Multiple vertical window splitting. Minimum pane size is four lines, an

(unhelpful) error will be shown if attempting to split a window with less

that eight lines. If the window is resized, as many panes are shown as can

fit without reducing them below four lines. There is (currently!) not a way

to show a hidden pane without making the window larger.

Note the -p and -l options to split-window are now gone, these may reappear

once I think them through again.

* Server locking on inactivity (lock-after-time) is now disabled by default.

13 January 2009

* kill-pane command.

12 January 2009

* command-prompt now accepts a single argument, a template string. Any

occurrences of %% in this string are replaced by whatever is entered at the

prompt and the result is executed as a command. This allows things like (now

bound by default):

bind , command-prompt "rename-window %%"

Or my favourite:

bind x command-prompt "split-window 'man %%'"

* Option to set prefix time, allowing multiple commands to be entered without

pressing the prefix key again, so long as they each typed within this time of

each other.

* Yet more hacks for key handling. Think it is just about working now.

* Two commands, resize-pane-up and resize-pane-down to resize a pane.

* Make the window pane code handle panes of different sizes, and add a -l

and -p arguments to split-window to specify the new window size in lines

or as a percentage.

11 January 2009

* Vertical window splitting. Currently can only split a window into two panes.

New split-window command splits (bound to ") and switch-pane command (bound to

o) switches between panes.

close-pane, swap-pane commands are to follow. Also to come are pane resizing,

>2 panes, the ability to break a pane out to a full window and vice versa and

possibly horizontal splitting.

Panes are subelements of windows rather than being windows in their own

right. I tried to make them windows (so the splitting was at the session or

client level) but this rapidly became very complex and invasive. So in the

interests of having something working, I just made it so each window can have

two child processes instead of one (and it still took me 12 hours straight

coding). Now the concept is proven and much of the support code is there,

this may change in future if more flexibility is needed.

* save-buffer command, from Tiago Cunha.

* New option, lock-after-time. If there is no activity in the period specified

by this option (in seconds), tmux will lock the server. Default is 1800 (30

minutes), set to 0 to disable.

* Server locking. Two new commands: set-password to set a password (a

preencrypted password may be specified with -c); and lock-server to lock the

server until the password is entered. Also an additional command line flag,

-U, to unlock from the shell. The default password is blank (any password

accepted). If specifying an encrypted password from encrypt(1) in .tmux.conf

with -c, don't forget to enclose it in single-quotes (') to prevent shell

variable expansion.

* If a window is created from the command line, tmux will now use the same

current working directory for the new process. A new default-path option to

sets the working directory for processes created from keys or interactively

from the prompt.

* New mode to display a large clock. Entered with clock-mode command (bound to

C-b t by default); two window options: clock-mode-colour and clock-mode-style

(12 or 24). This will probably be used as the basis for window locking.

* New command, server-info, to show some server information and terminal

details.

09 January 2009

* Stop using ncurses variables and instead build a table of the codes we want

into an array for each terminal type. This makes the code a little more

untidy in places but gets rid of the awful global variables and calling

setterm all the time, and shoves all the ncurses-dependent mess into a single

file, tty-term.c. It also allows overriding single terminal codes, this is

used to fix rxvt on some platforms (where it is missing dch) and in future

may allow user customisation a la vim.

* Update key handling code. Simplify, support ctrl properly and add a new

window option (xterm-keys) to output xterm key codes including ctrl and,

if available, alt and shift.

08 January 2009

* If built without DEBUG (the release versions), don't cause a fatal error if

the grid functions notice an input error, just log and ignore the

request. This might mean me getting shouted at less often when bugs kill

long-running sessions, at least in release versions.

* Hopefully fix cursor out-of-bounds checking when writing to grid. When I

wrote the code I must have forgotten that the cursor can be one cell off the

right of the screen (yes, I know), so there were number of out-of-bounds/

overflow problems.

07 January 2009

* New flag to set and setw, -u, to unset an option (allowing it to inherit from)

the global options again.

* Added more info messages for options changes.

* A bit of tidying and reorganisation of options code.

06 January 2009

* Don't crash when backspacing if cursor is off the right of the screen,

reported by David Chisnall.

* Complete words at any point inside command in prompt, also use option name

as well as command names.

* Per-client prompt history of up to 100 items.

* Use a splay tree for key bindings instead of an array. As a side-effect this

sorts them when listed.

22 December 2008

* Use the right keys for home and end.

20 December 2008

* Add vim mode for tmux configuration file to examples/, from Tiago Cunha.

15 December 2008

* New command, source-file (alias source), to load a configuration

file. Written by Tiago Cunha, many thanks.

13 December 2008

* Work around lack of dch. On Linux, the rxvt termcap doesn't have it (it is

lying, but we can't really start disbelieving termcaps...). This is a bit

horrible - I can see no way to do it without pretty much redrawing the whole

line, but it works...

10 December 2008

* glibc's getopt(3) is useless: it is not POSIX compliant without jumping

through non-portable hoops, and the method of resetting it is unclear (the

man page on my system says set optind to 1, but other sources say 0). So,

import OpenBSD's getopt_long.c into compat/ for use on Linux and use the

clearly documented optreset = optind = 1 method. This fixes some strange

issues with command parsing (getting the syntax wrong would prevent any

further commands being parsed).

06 December 2008

* Bring set/setw/show/showw into line with other commands. This means that by

default they now affect the current window (if any); the new -g flag must be

passed to set the global options. This changes the behaviour of set/show and

WILL BREAK CURRENT CONFIGURATIONS.

In summary, whether in the configuration file, the command prompt, or a key

binding, use -g to set a global option, use -t to specify a particular window

or session, or omit both to try and use the current window or session.

This makes set/show a bit of a pain but is the correct behaviour for

setw/showw and is the same as every other command, so we can put up with a

bit of pain for consistency.

* Redo window options. They now work in the same way to session options with a

global options set. showw/setw commands now have similar syntax to show/set

(including the ability to use abbreviations).

PLEASE NOTE this includes the following configuration-breaking changes:

- remain-by-default is now GONE, use "setw -g remain-on-exit" to apply the

global window option instead;

- mode-keys is now a window option rather than session - use "setw [-g]

mode-keys" instead of set.

There are also some additions:

- message-fg and message-bg session options to control status line message

colours;

- mode-fg and mode-bg window options to set colours in window modes such as

copy mode.

The options code still a mess and now there is twice as much of it :-(.

02 December 2008

* Add support for including the window title in status-left or status-right

strings by including the character pair "#T". This may be prefixed with

a number to specify a maximum length, for example "#24T" to use at most

24 characters of the title.

* Introduce two new options, status-left-length and status-right-length,

control the maximum length of left and right components of the status bar.

* elinks (and possibly others) bypass the terminal and talk directly to X to

restore the window title when exiting. tmux can't know about this particular

bit of stupidity so the title ends up strange - the prefix isn't terribly

important and elinks is quite useful so just get rid of it.

27 November 2008

* Tweaks to support Dragonfly.

17 November 2008

* tmux 0.5 released.

16 November 2008

* New window option: "utf8"; this must be on (it is off by default) for UTF-8

to be parsed. The global/session option "utf8-default" controls the setting

for new windows.

This means that by default tmux does not handle UTF-8. To use UTF-8 by

default it is necessary to a) "set utf8-default on" in .tmux.conf b) start

tmux with -u on any terminal which support UTF-8.

It seems a bit unnecessary for this to be a per-window option but that is

the easiest way to do it, and it can't do any harm...

* Enable default colours if op contains \033[39;49m, based on a report from

fulvio ciriaco.

12 November 2008

* Keep stack of last windows rather than just most recent; based on a diff from

joshe.

04 November 2008

* Don't try to redraw status line when showing a prompt or message; if it does,

the status timer is never reset so it redraws on every loop. Spotted by

joshe.

09 October 2008

* Translate 256 colours into 16 if 256 is not available, same as screen does.

* Better support for OSC command (only to set window title now), and also

support using APC for the same purpose (some Linux default shell profiles do

this).

25 September 2008

* Large internal rewrite to better support 256 colours and UTF-8. Screen data

is now stored as single two-way array of structures rather than as multiple

separate arrays. Also simplified a lot of code.

Only external changes are three new flags, -2, -d and -u, which force tmux to

assume the terminal supports 256 colours, default colours (useful for

xterm-256color which lacks the AX flag), or UTF-8 respectively.

10 September 2008

* Split off colour conversion code from screen code.

09 September 2008

* Initial UTF-8 support. A bit ugly and with a limit of 4096 UTF-8

characters per window.

08 September 2008

* 256 colour support. tmux attempts to autodetect the terminal by looking

both at what ncurses reports (usually wrong for xterm) and checking if

the TERM contains "256col". For xterm TERM=xterm-256color is needed (as

well as a build that support 256 colours); this seems to work for rxvt

as well. On non-256 colour terminals, high colours are translated to white

foreground and black background.

28 August 2008

* Support OS X/Darwin thanks to bsd-poll.c from OpenSSH. Also convert

from clock_gettime(2) to gettimeofday(2) as OS X doesn't support the

former; microsecond accuracy will have to be sufficient ;-).

07 August 2008

* Lose some unused/useless wrapper functions.

25 July 2008

* Shell variables may now be defined and used in configuration file. Define

variables with:

VAR=1

And use with:

renamew ${VAR}

renamew "x${VAR}x"

Also some other fixes to make, for example, "abc""abc" work similarly to

the shell.

24 July 2008

* Finally lose inconsistently-used SCREEN_DEF* defines.

* If cursor mode is on, switch the arrow keys from \033[A to \033OA.

* Support the numeric keypad in both application and numbers mode. This is

different from screen which always keeps it in application mode.

19 July 2008

* Unbreak "set status" - tmux thought it was ambiguous, reported by rivo nurges.

02 July 2008

* Split vi and emacs mode keys into two tables and add an option (mode-keys)

to select between them. Default is emacs, use,

tmux set mode-keys vi

to change to vi.

vi mode uses space to start selection, enter to copy selection and escape

to clear selection.

01 July 2008

* Protocol versioning. Clients which identify as a different version from the

server will be rejected.

* tmux 0.4 released.

29 June 2008

* Zombie windows. These are not closed when the child process dies. May be

set for a window with the new "remain-on-exit" option; the default setting

of this flag for new windows may be set with the "remain-by-default" session

option.

A window may be restarted with the respawn-window command:

respawn-window [-k] [command]

If -k is given, any existing process running in the window is killed;

if command is omitted, the same command as when the window was first

created is used.

27 June 2008

* Handle nonexistent session or client to -t properly.

25 June 2008

* select-prompt command to allow a window to be selected at a prompt. Only

windows in the current session may be selected. Bound to ' by default.

Suggested by merdely.

* move-window command. Requested by merdely.

* Support binding alt keys (prefixed with M-). Change default to use

C- for ctrl keys (^ is still accepted as an alternative).

* Slim down default key bindings: support lowercase only.

* Handle escaped keys properly (parse eg \033b into a single key code) and

use this to change copy mode next/previous work to M-f and M-b to match

emacs.

24 June 2008

* Next word (C-n/w) and previous word (C-b/b) in copy mode.

23 June 2008

* list-commands command (alias lscm).

* Split information about options into a table and use it to parse options

on input (allowing abbreviations) and to print them with show-options

(meaning that bell-action gets a proper string). This turned out a bit ugly

though :-/.

22 June 2008

* Do not translate black and white into default if the terminal supports

default colours. This was nice to force programs which didn't use default

colours to be properly transparent in rxvt/aterm windows with a background

image, but it causes trouble if someone redefines the default foreground and

background (to have black on white or something).

21 June 2008

* Naive tab completion in the command prompt. This only completes command

names if a) they are at the start of the text b) the cursor is at

the end of the text c) the text contains no spaces.

* Only attempt to set the title where TERM looks like an xterm (contains

"xterm", "rxvt" or is "screen"). I hate this but I don't see a better way:

setting the title actually kills some other terminals pretty much dead.

* Strip padding out of terminfo(5) strings. Currently the padding is just

ignored, this may need to be altered if there are any software terminals

out there that actually need it.

20 June 2008

* buffer-limit option to set maximum size of buffer stack. Default is 9.

* Initial buffer improvements. Each session has a stack of buffers and each

buffer command takes a -b option to manipulate items on the stack. If -b

is omitted, the top entry is used. The following commands are currently

available:

set-buffer [-b index] [-t target-session] string

paste-buffer [-d] [-b index] [-t target-window]

delete-buffer [-b index] [-t target-session]

show-buffers [-t target-session]

show-buffer [-b index] [-t target-session]

-d to paste-buffer deletes the buffer after pasting it.
