CHANGES FROM 3.0 to X.X
* Change file reading and writing to go through the client if necessary. This
fixes commands like "tmux loadb /dev/fd/X". Also modify source-file to
support "-" for standard input, like load-buffer and save-buffer.
* Add ~/.config/tmux/tmux.conf to the default search path for configuration
files.
* Bump the escape sequence timeout to five seconds to allow for longer
legitimate sequences.
* Make a best effort to set xpixel and ypixel for each pane and add formats for
them.
* Add push-default to status-left and status-right in status-format[0].
* Add -F flag to send-keys to expand formats in search-backward and forward
copy mode commands and copy_cursor_word and copy_cursor_line formats for word
and line at cursor in copy mode. Use for default # and * binding with vi(1)
keys.
* Do not clear search marks on cursor movement with vi(1) keys.
* Add p format modifier for padding to width and allow multiple substitutions
in a single format.
* Add -f for full size to join-pane (like split-window).
* Handle OSC 7 (a VTE extension) and put the result in a new format (pane_path).
* Change new-session -A without a session name (that is, no -s option also) to
attach to the best existing session like attach-session rather than creating
a new one.
* Add an option to set the key sent by backspace for those whose system uses ^H
rather than ^?.
* Add formats for cursor and selection position in copy mode.
* Add support for percentage sizes for resize-pane ("-x 10%"). Also change
split-window and join-pane -l to accept similar percentages and no longer
document -p.
* Turn automatic-rename back on if the rename escape sequence is used with an
empty name.
* Make select-pane -P set window-active-style also to match previous behaviour.
* Do not use bright when emulating 256 colours on an 8 colour terminal because
it is also bold on some terminals.
* Add a "latest" window-size option which tries to size windows based on the
most recently used client. This is now the default.
* Make select-pane -P set window-active-style also to match previous behaviour.
* Do not truncate list-keys output.
* Turn automatic-rename back on if the \033k rename escape sequence is used
with an empty name.
* Add support for percentage sizes for resize-pane ("-x 10%"). Also change
split-window and join-pane -l to accept similar percentages and deprecate the
-p flag.
* Add -F flag to send-keys to expand formats in search-backward and forward
copy mode commands, this makes it easier to use the cursor_word and
cursor_line formats.
* Add formats for word and line at cursor position in copy mode.
* Add formats for cursor and selection position in copy mode
* Support all the forms of RGB colour strings in OSC sequences rather than
requiring two digits.
* Limit lazy resize to panes in attached sessions only
* Add an option to set the key sent by backspace for those whose system uses ^H
rather than ^?.
* Change new-session -A without a session name (that is, no -s option also) to
attach to the best existing session like attach-session rather than a new
one.
* Change window-size default from smallest to latest.
* Add simple support for OSC 7 (result is available in the pane_path format).
* Add push-default and pop-default for styles which change the colours and
attributes used for #[default]. These are used in status-format to restore
the behaviour of window-status-style being the default for
window-status-format.
* Add window_marked_flag.
* Add cursor-down-and-cancel in copy mode.
* Default to previous search string for search-forward and search-backward.
* Add -Z flag to rotate-window, select-pane, swap-pane, switch-client to
preserve zoomed state.
* Add -N to capture-pane to preserve trailing spaces.
* Add reverse sorting in tree, client and buffer modes.
CHANGES FROM 3.0 to 3.0a
* Do not require REG_STARTEND.
* Respawn panes or windows correctly if default-command is set.
* Add missing option for after-kill-pane hook.
* Fix for crash with a format variable that doesn't exist.
* Do not truncate list-keys output on some platforms.
* Do not crash when restoring a layout with only one pane.
CHANGES FROM 2.9 to 3.0
* Workaround invalid layout strings generated by older tmux versions and add
some additional sanity checks
* xterm 348 now disables margins when resized, so send DECLRMM again after
resize.
* Add support for the SD (scroll down) escape sequence.
* Expand arguments to C and s format modifiers to match the m modifier.
* Add support for underscore colours (Setulc capability must be added with
terminal-overrides as described in tmux(1)).
* Add a "fill" style attribute for the fill colour of the drawing area (where
appropriate).
* New -H flag to send-keys to send literal keys.
* Format variables for pane mouse modes (mouse_utf8_flag and mouse_sgr_flag)
and for origin mode (origin_flag).
* Add -F to refresh-client for flags for control mode clients, only one flag
(no-output) supported at the moment.
* Add a few vi(1) keys for menus.
* Add pane options, set with set-option -p and displayed with show-options -p.
Pane options inherit from window options (so every pane option is also
a window option). The pane style is now configured by setting window-style
and window-active-style in the pane options; select-pane -P and -g now change
the option but are no longer documented.
* Do not document set-window-option and show-window-options. set-option -w and
show-options -w should be used instead.
* Add a -A flag to show-options to show parent options as well (they are marked
with a *).
* Resize panes lazily - do not resize unless they are in an attached, active
window.
* Add regular expression support for the format search, match and substitute
modifiers and make them able to ignore case. find-window now accepts -r to
use regular expressions.
* Do not use $TMUX to find the session because for windows in multiple sessions
it is wrong as often as it is right, and for windows in one session it is
pointless. Instead use TMUX_PANE if it is present.
* Do not always resize the window back to its original size after applying a
layout, keep it at the layout size until it must be resized (for example when
attached and window-size is not manual).
* Add new-session -X and attach-session -x to send SIGHUP to parent when
detaching (like detach-client -P).
* Support for octal escapes in strings (such as \007) and improve list-keys
output so it parses correctly if copied into a configuration file.
* INCOMPATIBLE: Add a new {} syntax to the configuration file. This is a string
similar to single quotes but also includes newlines and allows commands that
take other commands as string arguments to be expressed more clearly and
without additional escaping.
A literal { and } or a string containing { or } must now be escaped or
quoted, for example '{' and '}' instead of { or }, or 'X#{foo}' instead of
X#{foo}.
* New <, >, <= and >= comparison operators for formats.
* Improve escaping of special characters in list-keys output.
* INCOMPATIBLE: tmux's configuration parsing has changed to use yacc(1). There
is one incompatible change: a \ on its own must be escaped or quoted as
either \\ or '\' (the latter works on older tmux versions).
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
* Add support for the overline attribute (SGR 53). The Smol capability is
needed in terminal-overrides.
* Add the ability to create simple menus. Introduces new command
display-menu. Default menus are bound to MouseDown3 on the status line;
MouseDown3 or M-MouseDown3 on panes; MouseDown3 in tree, client and
buffer modes; and C-b < and >.
* Allow panes to be empty (no command). They can be created either by piping to
split-window -I, or by passing an empty command ('') to split-window. Output
can be sent to an existing empty window with display-message -I.
* Add keys to jump between matching brackets (emacs C-M-f and C-M-b, vi %).
* Add a -e flag to new-window, split-window, respawn-window, respawn-pane to
pass environment variables into the newly created process.
* Hooks are now stored in the options tree as array options, allowing them to
have multiple separate commands. set-hook and show-hooks remain but
set-option and show-options can now also be used (show-options will only show
hooks if given the -H flag). Hooks with multiple commands are run in index
order.
* Automatically scroll if dragging to create a selection with the mouse and the
cursor reaches the top or bottom line.
* Add -no-clear variants of copy-selection and copy-pipe which do not clear the
selection after copying. Make copy-pipe clear the selection by default to be
consistent with copy-selection.
* Add an argument to copy commands to set the prefix for the buffer name, this
(for example) allows buffers for different sessions to be named separately.
* Update session activity on focus event.
* Pass target from source-file into the config file parser so formats in %if
and %endif have access to more useful variables.
* Add the ability to infer an option type (server, session, window) from its
name to show-options (it was already present in set-option).
CHANGES FROM 2.9 to 2.9a
* Fix bugs in select-pane and the main-horizontal and main-vertical layouts.
CHANGES FROM 2.8 to 2.9
* Attempt to preserve horizontal cursor position as well as vertical with
reflow.
* Rewrite main-vertical and horizontal and change layouts to better handle the
case where all panes won't fit into the window size, reduce problems with
pane border status lines and fix other bugs mostly found by Thomas Sattler.
* Add format variables for the default formats in the various modes
(tree_mode_format and so on) and add a -a flag to display-message to list
variables with values.
* Add a -v flag to display-message to show verbose messages as the format is
parsed, this allows formats to be debugged
* Add support for HPA (\033[`).
* Add support for origin mode (\033[?6h).
* No longer clear history on RIS.
* Extend the #[] style syntax and use that together with previous format
changes to allow the status line to be entirely configured with a single
option.
Now that it is possible to configure their content, enable the existing code
that lets the status line be multiple lines in height. The status option can
now take a value of 2, 3, 4 or 5 (as well as the previous on or off) to
configure more than one line. The new status-format array option configures
the format of each line, the default just references the existing status-*
options, although some of the more obscure status options may be eliminated
in time.
Additions to the #[] syntax are: "align" to specify alignment (left, centre,
right), "list" for the window list and "range" to configure ranges of text
for the mouse bindings.
The "align" keyword can also be used to specify alignment of entries in tree
mode and the pane status lines.
* Add E: and T: format modifiers to expand a format twice (useful to expand the
value of an option).
* The individual -fg, -bg and -attr options have been removed; they
were superseded by -style options in tmux 1.9.
* Allow more than one mode to be opened in a pane. Modes are kept on a stack
and retrieved if the same mode is entered again. Exiting the active mode goes
back to the previous one.
* When showing command output in copy mode, call it view mode instead (affects
pane_mode format).
* Add -b to display-panes like run-shell.
* Handle UTF-8 in word-separators option.
* New "terminal" colour allowing options to use the terminal default colour
rather than inheriting the default from a parent option.
* Do not move the cursor in copy mode when the mouse wheel is used.
* Use the same working directory rules for jobs as new windows rather than
always starting in the user's home.
* Allow panes to be one line or column in size.
* Go to last line when goto-line number is out of range in copy mode.
* Yank previously cut text if any with C-y in the command prompt, only use the
buffer if no text has been cut.
* Add q: format modifier to quote shell special characters.
* Add StatusLeft and StatusRight mouse locations (keys such as
MouseDown1StatusLeft) for the status-left and status-right areas of the
status line.
* Add -Z to find-window.
* Support for windows larger than the client. This adds two new options,
window-size and default-size, and a new command, resize-window. The
force-width and force-height options and the session_width and session_height
formats have been removed.
The new window-size option tells tmux how to work out the size of windows:
largest means it picks the size of the largest session, smallest the smallest
session (similar to the old behaviour) and manual means that it does not
automatically resize windows. aggressive-resize modifies the choice of
session for largest and smallest as it did before.
If a window is in a session attached to a client that is too small, only part
of the window is shown. tmux attempts to keep the cursor visible, so the part
of the window displayed is changed as the cursor moves (with a small delay,
to try and avoid excess redrawing when applications redraw status lines or
similar that are not currently visible).
Drawing windows which are larger than the client is not as efficient as those
which fit, particularly when the cursor moves, so it is recommended to avoid
using this on slow machines or networks (set window-size to smallest or
manual).
The resize-window command can be used to resize a window manually. If it is
used, the window-size option is automatically set to manual for the window
(undo this with "setw -u window-size"). resize-window works in a similar way
to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a
sets the window to the size of the smallest client (what it would be if
window-size was smallest) and -A the largest.
For the same behaviour as force-width or force-height, use resize-window -x
or -y.
If the global window-size option is set to manual, the default-size option is
used for new windows. If -x or -y is used with new-session, that sets the
default-size option for the new session.
The maximum size of a window is 10000x10000. But expect applications to
complain and higher memory use if making a window that big. The minimum size
is the size required for the current layout including borders.
The refresh-client command can be used to pan around a window, -U -D -L -R
moves up, down, left or right and -c returns to automatic cursor
tracking. The position is reset when the current window is changed.
CHANGES FROM 2.7 to 2.8
* Make display-panes block the client until a pane is chosen or it
times out.
* Clear history on RIS like most other terminals do.
* Add an "Any" key to run a command if a key is pressed that is not
bound in the current key table.
* Expand formats in load-buffer and save-buffer.
* Add a rectangle_toggle format.
* Add set-hook -R to run a hook immediately.
* Add README.ja.
* Add pane focus hooks.
* Allow any punctuation as separator for s/x/y not only /.
* Improve resizing with the mouse (fix resizing the wrong pane in some
layouts, and allow resizing multiple panes at the same time).
* Allow , and } to be escaped in formats as #, and #}.
* Add KRB5CCNAME to update-environment.
* Change meaning of -c to display-message so the client is used if it
matches the session given to -t.
* Fixes to : form of SGR.
* Add x and X to choose-tree to kill sessions, windows or panes.
CHANGES FROM 2.6 TO 2.7
* Remove EVENT_* variables from environment on platforms where tmux uses them
so they do not pass on to panes.
* Fixes for hooks at server exit.
* Remove SGR 10 (was equivalent to SGR 0 but no other terminal seems to do
this).
* Expand formats in window and session names.
* Add -Z flag to choose-tree, choose-client, choose-buffer to automatically
zoom the pane when the mode is entered and unzoom when it exits, assuming the
pane is not already zoomed. This is now part of the default key bindings.
* Add C-g to exit modes with emacs keys.
* Add exit-empty option to exit server if no sessions (defaults to on).
* Show if a filter is present in choose modes.
* Add pipe-pane -I to to connect stdin of the child process.
* Performance improvements for reflow.
* Use RGB terminfo(5) capability to detect RGB colour terminals (the existing
Tc extension remains unchanged).
* Support for ISO colon-separated SGR sequences.
* Add select-layout -E to spread panes out evenly (bound to E key).
* Support wide characters properly when reflowing.
* Pass PWD to new panes as a hint to shells, as well as calling chdir().
* Performance improvements for the various choose modes.
* Only show first member of session groups in tree mode (-G flag to choose-tree
to show all).
* Support %else in config files to match %if; from Brad Town in GitHub issue
1071.
* Fix "kind" terminfo(5) capability to be S-Down not S-Up.
* Add a box around the preview label in tree mode.
* Show exit status and time in the remain-on-exit pane text; from Timo
Boettcher in GitHub issue 1103.
* Correctly use pane-base-index in tree mode.
* Change the allow-rename option default to off.
* Support for xterm(1) title stack escape sequences (GitHub issue 1075 from
Brad Town).
* Correctly remove padding cells to fix a UTF-8 display problem (GitHub issue
1090).
CHANGES FROM 2.5 TO 2.6, 05 October 2017
* Add select-pane -T to set pane title.
* Fix memory leak when lines with BCE are removed from history.
* Fix (again) the "prefer unattached" behaviour of attach-session.
* Reorder how keys are checked to allow keys to be specified that have a
leading escape. GitHub issue 1048.
* Support REP escape sequence (\033[b).
* Run alert hooks based on options rather than always, and allow further bells
even if there is an existing bell.
* Add -d flag to display-panes to override display-panes-time.
* Add selection_present format when in copy mode (allows key bindings that do
something different if there is a selection).
* Add pane_at_left, pane_at_right, pane_at_top and pane_at_bottom formats.
* Make bell, activity and silence alerting more consistent by: removing the
bell-on-alert option; adding activity-action and silence-action options with
the same possible values as the existing bell-action; adding a "both" value
for the visual-bell, visual-activity and visual-silence options to trigger
both a bell and a message.
* Add a pane_pipe format to show if pipe-pane is active.
* Block signals between forking and resetting signal handlers so that the
libevent signal handler doesn't get called in the child and incorrectly write
into the signal pipe that it still shares with the parent. GitHub issue 1001.
* Allow punctuation in pane_current_command.
* Add -c for respawn-pane and respawn-window.
* Wait for any remaining data to flush when a pane is closed while pipe-pane is
in use.
* Fix working out current client with no target. GitHub issue 995.
* Try to fallback to C.UTF-8 as well as en_US.UTF-8 when looking for a UTF-8
locale.
* Add user-keys option for user-defined key escape sequences (mapped to User0
to User999 keys).
* Add pane-set-clipboard hook.
* FAQ file has moved out of repository to online.
* Fix problem with high CPU usage when a client dies unexpectedly. GitHub issue
941.
* Do a dance on OS X 10.10 and above to return tmux to the user namespace,
allowing access to the clipboard.
* Do not allow escape sequences which expect a specific terminator (APC, DSC,
OSC) to wait for forever - use a small timeout. This reduces the chance of
the pane locking up completely when sent garbage (cat /dev/random or
similar).
* Support SIGUSR2 to toggle logging on a running server, also generate the
"out" log file with -vv not -vvvv.
* Make set-clipboard a three state option: on (tmux both sends to outside
terminal and accepts from applications inside); external (tmux sends outside
but does not accept inside); and off.
* Fix OSC 4 palette setting for bright foreground colours. GitHub issue 954.
* Use setrgbf and setrgbb terminfo(5) capabilities to set RGB colours, if they
are available. (Tc is still supported as well.)
* Fix redrawing panes when they are resized several times but end up with the
size unchanged (for example, splitw/resizep -Z/breakp).
* Major rewrite of choose mode. Now includes preview, sorting, searching and
tagging; commands that can be executed directly from the mode (for example,
to delete one or more buffers); and filtering in tree mode.
* choose-window and choose-session are now aliases of choose-tree (in the
command-alias option).
* Support OSC 10 and OSC 11 to set foreground and background colours.
* Check the U8 capability to determine whether to use UTF-8 line drawing
characters for ACS.
* Some missing notifications for layout changes.
* Control mode clients now do not affect session sizes until they issue
refresh-client -C. new-session -x and -y works with control clients even if
the session is not detached.
* All new sessions that are unattached (whether with -d or started with no
terminal) are now created with size 80 x 24. Whether the status line is on or
off does not affect the size of new sessions until they are attached.
* Expand formats in option names and add -F flag to expand them in option values.
* Remember the search string for a pane even if copy mode is exited and entered
again.
* Some further BCE fixes (scroll up, reverse index).
* Improvements to how terminals are cleared (entirely or partially).
CHANGES FROM 2.4 TO 2.5, 09 May 2017
* Reset updated flag when restarting #() command so that new output is properly
recognised. GitHub issue 922.
* Fix ECH with a background colour.
* Do not rely on the terminal not moving the cursor after DL or EL.
* Fix send-keys and send-prefix in copy-mode (so C-b C-b works). GitHub issue
905.
* Set the current pane for rotate-window so it works in command sequences.
* Add pane_mode format.
* Differentiate M-Up from Escape+Up when possible (that is, in terminals with
xterm(1) style function keys). GitHub issue 907.
* Add session_stack and window_stack_index formats.
* Some new control mode notifications and corresponding hooks:
pane-mode-changed, window-pane-changed, client-session-changed,
session-window-changed.
* Format pane_search_string for last search term while in copy mode (useful
with command-prompt -I).
* Fix a problem with high CPU usage and multiple clients with #(). GitHub issue
889.
* Fix UTF-8 combining characters in column 0.
* Fix reference counting so that panes are properly destroyed and their
processes killed.
* Clamp SU (CSI S) parameter to work around a bug in Konsole.
* Tweak line wrapping in full width panes to play more nicely with terminal
copy and paste.
* Fix when we emit SGR 0 in capture-pane -e.
* Do not change TERM until after config file parsing has finished, so that
commands run inside the config file can use it to make decisions (typically
about default-terminal).
* Make the initial client wait until config file parsing has finished to avoid
racing with commands.
* Fix core when if-shell fails.
* Only use ED to clear screen if the pane is at the bottom.
* Fix multibyte UTF-8 output.
* Code improvements around target (-t) resolution.
* Change how the default target (for commands without -t) is managed across
command sequences: now it is set up at the start and commands are required
to update it if needed. Fixes binding command sequences to mouse keys.
* Make if-shell from the config file work correctly.
* Change to always check the root key table if no binding is found in the
current table (prefix table or copy-mode table or whatever). This means that
root key bindings will take effect even in copy mode, if not overridden by a
copy mode key binding.
* Fix so that the history file works again.
* Run config file without a client rather than using the first client, restores
previous behaviour.
* If a #() command doesn't exit, continue to read from it and use its last full
line of output.
* Handle slow terminals and fast output better: when the amount of data
outstanding gets too large, discard output until it is drained and we are
able to do a full redraw. Prevents tmux sitting on a huge buffer that the
terminal will take forever to consume.
* Do not redraw a client unless we realistically think it can accept the data -
defer redraws until the client has nothing else waiting to write.
CHANGES FROM 2.3 TO 2.4, 20 April 2017
Incompatible Changes
====================
* Key tables have undergone major changes. Mode key tables are no longer
separate from the main key tables. All mode key tables have been removed,
together with the -t flag to bind-key and unbind-key.
The emacs-edit, vi-edit, emacs-choose and vi-choose tables have been replaced
by fixed key bindings in the command prompt and choose modes. The mode-keys
and status-keys options remain.
The emacs-copy and vi-copy tables have been replaced by the copy-mode and
copy-mode-vi tables. Commands are sent using the -X and -N flags to
send-keys. So the following:
bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up
Becomes:
bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
These changes allows the full command parser (including command sequences) and
command set to be used - for example, the normal command prompt with editing
and history is now used for searching, jumping, and so on instead of a custom
one. The default C-r binding is now:
bind -Tcopy-mode C-r command-prompt -i -p'search up' "send -X search-backward-incremental '%%'"
There are also some new commmands available with send -X, such as
copy-pipe-and-cancel.
* set-remain-on-exit has gone -- can be achieved with hooks instead.
* Hooks: before hooks have been removed and only a selection of commands now
have after hooks (they are no longer automatic). Additional hooks have been
added.
* The xterm-keys option now defaults to on.
Normal Changes
==============
* Support for mouse double and triple clicks.
* BCE (Background Colour Erase) is now supported.
* All occurrences of a search string in copy mode are now highlighted;
additionally, the number of search results is displayed. The highlighting
updates interactively with the default emacs key bindings (incremental
search).
* source-file now understands glob patterns.
* Formats now have simple comparisons:
#{==:a,b}
#{!=:a,b}
* There are the following new formats:
- #{version} -- the tmux server version;
- #{client_termtype} -- the terminal type of the client;
- #{client_name} -- the name of a client;
- #{client_written} -- the number of bytes written to the client.
* The configuration file now accepts %if/%endif conditional blocks which are
processed when it is parsed; the argument is a format string (useful with the
new format comparison options).
* detach-client now has -E to execute a command replacing the client instead of
exiting.
* Add support for custom command aliases, this is an array option which
contains items of the form "alias=command". This is consulted when an
unknown command is parsed.
* break-pane now has -n to specify the new window name.
* OSC 52 support has been added for programs inside tmux to set a tmux buffer.
* The mouse "all event" mode (1003) is now supported.
* Palette setting is now possible (OSC 4 and 104).
* Strikethrough support (a recent terminfo is required).
* Grouped sessions can now be named (new -t).
* terminal-overrides and update-environment are now array options (the previous
set -ag syntax should work without change).
* There have been substantial performance improvements.
CHANGES FROM 2.2 TO 2.3, 29 September 2016
Incompatible Changes
====================
None.
Normal Changes
==============
* New option 'pane-border-status' to add text in the pane borders.
* Support for hooks on commands: 'after' and 'before' hooks.
* 'source-file' understands '-q' to suppress errors for nonexistent files.
* Lots of UTF8 improvements, especially on MacOS.
* 'window-status-separator' understands #[] expansions.
* 'split-window' understands '-f' for performing a full-width split.
* Allow report count to be specified when using 'bind-key -R'.
* 'set -a' for appending to user options (@foo) is now supported.
* 'display-panes' can now accept a command to run, rather than always
selecting the pane.
CHANGES FROM 2.1 TO 2.2, 10 April 2016
Incompatible Changes
====================
* The format strings which referenced time have been removed. Instead:
#{t:window_activity}
can be used.
* Support for TMPDIR has been removed. Use TMUX_TMPDIR instead.
* UTF8 detection now happens automatically if the client supports it, hence
the:
mouse-utf8
utf8
options has been removed.
* The:
mouse_utf8_flag
format string has been removed.
* The -I option to show-messages has been removed. See:
#{t:start_time}
format option instead.
Normal Changes
==============
* Panes are unzoomed with selectp -LRUD
* New formats added:
#{scroll_position}
#{socket_path}
#{=10:...} -- limit to N characters (from the start)
#{=-10:...} -- limit to N characters (from the end)
#{t:...} -- used to format time-based formats
#{b:...} -- used to ascertain basename from string
#{d:...} -- used to ascertain dirname from string
#{s:...} -- used to perform substitutions on a string
* Job output is run via the format system, so formats work again
* If display-time is set to 0, then the indicators wait for a key to be
pressed.
* list-keys and list-commands can be run without starting the tmux server.
* kill-session learns -C to clear all alerts in all windows of the session.
* Support for hooks (internal for now), but hooks for the following have been
implemented:
alert-bell
alert-silence
alert-activity
client-attached
client-detached
client-resized
pane-died
pane-exited
* RGB (24bit) colour support. The 'Tc' flag must be set in the external TERM
entry (using terminal-overrides or a custom terminfo entry).
CHANGES FROM 2.0 TO 2.1, 18 October 2015
Incompatible Changes
====================
* Mouse-mode has been rewritten. There's now no longer options for:
- mouse-resize-pane
- mouse-select-pane
- mouse-select-window
- mode-mouse
Instead there is just one option: 'mouse' which turns on mouse support
entirely.
* 'default-terminal' is now a session option. Furthermore, if this is set
to 'screen-*' then emulate what screen does. If italics are wanted, this
can be set to 'tmux' but this is still new and not necessarily supported
on all platforms with older ncurses installs.
* The c0-* options for rate-limiting have been removed. Instead, a backoff
approach is used.
Normal Changes
==============
* New formats:
- session_activity
- window_linked
- window_activity_format
- session_alerts
- session_last_attached
- client_pid
- pid
* 'copy-selection', 'append-selection', 'start-named-buffer' now understand
an '-x' flag to prevent it exiting copying mode.
* 'select-pane' now understands '-P' to set window/pane background colours.
* 'renumber-windows' now understands windows which are unlinked.
* 'bind' now understands multiple key tables. Allows for key-chaining.
* 'select-layout' understands '-o' to undo the last layout change.
* The environment is updated when switching sessions as well as attaching.
* 'select-pane' now understands '-M' for marking a pane. This marked pane
can then be used with commands which understand src-pane specifiers
automatically.
* If a session/window target is prefixed with '=' then only an exact match
is considered.
* 'move-window' understands '-a'.
* 'update-environment' understands '-E' when attach-session is used on an
already attached client.
* 'show-environment' understands '-s' to output Bourne-compatible commands.
* New option: 'history-file' to save/restore command prompt history.
* Copy mode is exited if the history is cleared whilst in copy-mode.
* 'copy-mode' learned '-e' to exit copy-mode when scrolling to end.
CHANGES FROM 1.9a TO 2.0, 06 March 2015
Incompatible Changes
====================
* The choose-list command has been removed.
* 'terminal-overrides' is now a server option, not a session option.
* 'message-limit' is now a server option, not a session option.
* 'monitor-content' option has been removed.
* 'pane_start_path' option has been removed.
* The "info" mechanism which used to (for some commands) provide feedback
has been removed, and like other commands, they now produce nothing on
success.
Normal Changes
==============
* tmux can now write an entry to utmp if the library 'utempter' is present
at compile time.
* set-buffer learned append mode (-a), and a corresponding
'append-selection' command has been added to copy-mode.
* choose-mode now has the following commands which can be bound:
- start-of-list
- end-of-list
- top-line
- bottom-line
* choose-buffer now understands UTF-8.
* Pane navigation has changed:
- The old way of always using the top or left if the choice is ambiguous.
- The new way of remembering the last used pane is annoying if the
layout is balanced and the leftmost is obvious to the user (because
clearly if we go right from the top-left in a tiled set of four we want
to end up in top-right, even if we were last using the bottom-right).
So instead, use a combination of both: if there is only one possible
pane alongside the current pane, move to it, otherwise choose the most
recently used of the choice.
* 'set-buffer' can now be told to give names to buffers.
* The 'new-session', 'new-window', 'split-window', and 'respawn-pane' commands
now understand multiple arguments and handle quoting problems correctly.
* 'capture-pane' understands '-S-' to mean the start of the pane, and '-E-' to
mean the end of the pane.
* Support for function keys beyond F12 has changed. The following explains:
- F13-F24 are S-F1 to S-F12
- F25-F36 are C-F1 to C-F12
- F37-F48 are C-S-F1 to C-S-F12
- F49-F60 are M-F1 to M-F12
- F61-F63 are M-S-F1 to M-S-F3
Therefore, F13 becomes a binding of S-F1, etc.
* Support using pane id as part of session or window specifier (so % means
session-of-%1 or window-of-%1) and window id as part of session
(so @1 means session-of-@1).
* 'copy-pipe' command now understands formats via -F
* 'if-shell' command now understands formats via -F
* 'split-window' and 'join-window' understand -b to create the pane to the left
or above the target pane.
CHANGES FROM 1.9 TO 1.9a, 22 February 2014
NOTE: This is a bug-fix release to address some important bugs which just
missed the 1.9 deadline, but were found afterwards.
Normal Changes
==============
* Fix crash due to uninitialized lastwp member of layout_cell
* Fix -fg/-bg/-style with 256 colour terminals.
CHANGES FROM 1.8 TO 1.9, 20 February 2014
NOTE: This release has bumped the tmux protocol version. It is therefore
advised that the prior tmux server is restarted when this version of tmux is
installed, to avoid protocol mismatch errors for newer clients trying to
talk to an older running tmux server.
Incompatible Changes
====================
* 88 colour support has been removed.
* 'default-path' has been removed. The new-window command accepts '-c' to
cater for this. The previous value of "." can be replaced with: 'neww -c
$PWD', the previous value of '' which meant current path of the pane can
be specified as: 'neww -c "#{pane_current_path}"'
Deprecated Changes
==================
* The single format specifiers: #A -> #Z (where defined) have been
deprecated and replaced with longer-named equivalents, as listed in the
FORMATS section of the tmux manpage.
* The various foo-{fg,bg,attr} commands have been deprecated and replaced
with equivalent foo-style option instead. Currently this is still
backwards-compatible, but will be removed over time.
Normal Changes
==============
* A new environment variable TMUX_TMPDIR is now honoured, allowing the
socket directory to be set outside of TMPDIR (/tmp/ if not set).
* If -s not given to swap-pane the current pane is assumed.
* A #{pane_synchronized} format specifier has been added to be a conditional
format if a pane is in a synchronised mode (c.f. synchronize-panes)
* Tmux now runs under Cygwin natively.
* Formats can now be nested within each other and expanded accordingly.
* Added 'automatic-rename-format' option to allow the automatic rename
mechanism to use something other than the default of
#{pane_current_command}.
* new-session learnt '-c' to specify the starting directory for that session
and all subsequent windows therein.
* The session name is now shown in the message printed to the terminal when
a session is detached.
