blob: 519fde840dc4f5bad25038e4a991fe2118f65d8c [file] [log] [blame] [raw]
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.
* Lots more format specifiers have been added.
* Server race conditions have been fixed; in particular commands are not run
until after the configuration file is read completely.
* Case insensitive searching in tmux's copy-mode is now possible.
* attach-session and switch-client learnt the '-t' option to accept a window
and/or a pane to use.
* Copy-mode is only exited if no selection is in progress.
* Paste key in copy-mode is now possible to enter text from the clipboard.
* status-interval set to '0' now works as intended.
* tmux now supports 256 colours running under fbterm.
* Many bug fixes!
CHANGES FROM 1.7 TO 1.8, 26 March 2013
Incompatible Changes
====================
* layout redo/undo has been removed.
Normal Changes
==============
* Add halfpage up/down bindings to copy mode.
* Session choosing fixed to work with unattached sessions.
* New window options window-status-last-{attr,bg,fg} to denote the last
window which was active.
* Scrolling in copy-mode now scrolls the region without moving the mouse
cursor.
* run-shell learnt '-t' to specify the pane to use when displaying output.
* Support for middle-click pasting.
* choose-tree learns '-u' to start uncollapsed.
* select-window learnt '-T' to toggle to the last window if it's already
current.
* New session option 'assume-paste-time' for pasting text versus key-binding
actions.
* choose-* commands now work outside of an attached client.
* Aliases are now shown for list-commands command.
* Status learns about formats.
* Free-form options can be set with set-option if prepended with an '@'
sign.
* capture-pane learnt '-p' to send to stdout, and '-e' for capturing escape
sequences, and '-a' to capture the alternate screen, and '-P' to dump
pending output.
* Many new formats added (client_session, client_last_session, etc.)
* Control mode, which is a way for a client to send tmux commands.
Currently more useful to users of iterm2.
* resize-pane learnt '-x' and '-y' for absolute pane sizing.
* Config file loading now reports errors from all files which are loaded via
the 'source-file' command.
* 'copy-pipe' mode command to copy selection and pipe the selection to a
command.
* Panes can now emit focus notifications for certain applications
which use those.
* run-shell and if-shell now accept formats.
* resize-pane learnt '-Z' for zooming a pane temporarily.
* new-session learnt '-A' to make it behave like attach-session.
* set-option learnt '-o' to prevent setting an option which is already set.
* capture-pane and show-options learns '-q' to silence errors.
* New command 'wait-for' which blocks a client until woken up again.
* Resizing panes will now reflow the text inside them.
* Lots and lots of bug fixes, fixing memory-leaks, etc.
* Various manpage improvements.
CHANGES FROM 1.6 TO 1.7, 13 October 2012
* tmux configuration files now support line-continuation with a "\" at the
end of a line.
* New option status-position to move the status line to the top or bottom of
the screen.
* Enforce history-limit option when clearing the screen.
* Give each window a unique id, like panes but prefixed with @.
* Add pane id to each pane in layout description (while still accepting
the old form).
* Provide defined ways to set the various default-path possibilities: ~
for home directory, . for server start directory, - for session start
directory and empty for the pane's working directory (the default). All
can also be used as part of a relative path (eg -/foo). Also provide -c
flags to neww and splitw to override default-path setting.
* Add -l flag to send-keys to send input literally (without translating
key names).
* Allow a single option to be specified to show-options to show just that
option.
* New command "move-pane" (like join-pane but allows the same window).
* join-pane and move-pane commands learn "-b" option to place the pane to
the left or above.
* Support for bracketed-paste mode.
* Allow send-keys command to accept hex values.
* Add locking around "start-server" to avoid race-conditions.
* break-pane learns -P/-F arguments for display formatting.
* set-option learns "-q" to make it quiet, and not print out anything.
* copy mode learns "wrap-search" option.
* Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 250/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.
* find-window learns new flags: "-C", "-N", "-T" to match against either or
all of a window's content, name, or title. Defaults to all three options
if none specified.
* find-window automatically selects the appropriate pane for the found
matches.
* show-environment can now accept one option to show that environment value.
* Exit mouse mode when end-of-screen reached when scrolling with the mouse
wheel.
* select-layout learns -u and -U for layout history stacks.
* kill-window, detach-client, kill-session all learn "-a" option for
killing all but the current thing specified.
* move-window learns "-r" option to renumber window sequentially in a
session.
* New session option "renumber-windows" to automatically renumber windows in
a session when a window is closed. (see "move-window -r").
* Only enter copy-mode on scroll up.
* choose-* and list-* commands all use "-F" for format specifiers.
* When spawning external commands, the value from the "default-shell" option
is now used, rather than assuming /bin/sh.
* New choose-tree command to render window/sessions as a tree for selection.
* display-message learns new format options.
* For linked-windows across sessions, all flags for that window are now
cleared across sessions.
* Lots and lots of bug fixes, fixing memory-leaks, etc.
* Various manpage improvements.
CHANGES FROM 1.5 TO 1.6, 23 January 2012
* Extend the mode-mouse option to add a third choice which means the mouse
does not enter copy mode.
* Add a -r flag to switch-client to toggle the client read-only flag.
* Add pane-base-index option.
* Support \ for line continuation in the configuration file.
* Framework for more powerful formatting of command output and use it for
list-{panes,windows,sessions}. This allows more descriptive replacements
(such as #{session_name}) and conditionals.
* Mark dead panes with some text saying they are dead.
* Reject $SHELL if it is not a full path.
* Add -S option to refresh-client to redraw status line.
* Add an else clause for if-shell.
* Try to resolve relative paths for loadb and saveb (first, using client
working directory, if any, then default-path or session working directory).
* Support for \e[3J to clear the history and send the corresponding
terminfo code (E3) before locking.
* When in copy mode, make repeat count indicate buffer to replace, if used.
* Add screen*:XT to terminal-overrides for tmux-in-tmux.
* Status-line message attributes added.
* Move word-separators to be a session rather than window option.
* Change the way the working directory for new processes is discovered. If
default-path isn't empty, it is used. Otherwise, if a new window is created
from the command-line, the working directory of the client is used. If not,
platform specific code is used to retrieve the current working directory
of the process in the active pane. If that fails, the directory where the
session was created is used, instead.
* Do not change the current pane if both mouse-select-{pane,window} are
enabled.
* Add \033[s and \033[u to save and restore cursor position.
* Allow $HOME to be used as default-path.
* Add CNL and CPL escape sequences.
* Calculate last position correctly for UTF-8 wide characters.
* Add an option allow-rename to disable the window rename escape sequence.
* Attributes for each type of status-line alert (ie bell, content and
activity) added. Therefore, remove the superfluous options
window-status-alert-{attr,bg,fg}.
* Add a -R flag to send-keys to reset the terminal.
* Add strings to allow the aixterm bright colours to be used when
configuring colours.
* Drop the ability to have a list of keys in the prefix in favour of two
separate options, prefix and prefix2.
* Flag -2 added to send-prefix to send the secondary prefix key.
* Show pane size in top right of display panes mode.
* Some memory leaks plugged.
* More command-prompt editing improvements.
* Various manpage improvements.
* More Vi mode improvements.
CHANGES FROM 1.4 TO 1.5, 09 July 2011
* Support xterm mouse modes 1002 and 1003.
* Change from a per-session stack of buffers to one global stack. This renders
copy-buffer useless and makes buffer-limit now a server option.
* Fix most-recently-used choice by avoiding reset the activity timer for
unattached sessions every second.
* Add a -P option to new-window and split-window to print the new window or
pane index in target form (useful to pass it into other commands).
* Handle a # at the end of a replacement string (such as status-left)
correctly.
* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262.
If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the same
manner as the utf8 option.
* Support for HP-UX.
* Accept colours of the hex form #ffffff and translate to the nearest from the
xterm(1) 256-colour set.
* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors
before closing them (fixes things like "tmux ls && cat").
* Use TMPDIR if set.
* Fix next and previous session functions to actually work.
* Support -x and -y for new-session to specify the initial size of the window
if created detached with -d.
* Make bind-key accept characters with the top-bit-set and print them as octal.
* Set $TMUX without the session when background jobs are run.
* Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.
* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the
terminal disappears while locked.
* Add a -P option to detach to HUP the client's parent process (usually causing
it to exit as well).
* Support passing through escape sequences to the underlying terminal by using
DCS with a "tmux;" prefix.
* Prevent tiled producing a corrupt layout when only one column is needed.
* Give each pane created in a tmux server a unique id (starting from 0), put it
in the TMUX_PANE environment variable and accept it as a target.
* Allow a start and end line to be specified for capture-pane which may be
negative to capture part of the history.
* Add -a and -s options to lsp to list all panes in the server or session
respectively. Likewise add -s to lsw.
* Change -t on display-message to be target-pane for the #[A-Z] replacements
and add -c as target-client.
* The attach-session command now prefers the most recently used unattached
session.
* Add -s option to detach-client to detach all clients attached to a session.
* Add -t to list-clients.
* Change window with mouse wheel over status line if mouse-select-window is on.
* When mode-mouse is on, automatically enter copy mode when the mouse is
dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel
is scrolled off the bottom.
* Provide #h character pair for short hostname (no domain).
* Don't use strnvis(3) for the title as it breaks UTF-8.
* Use the tsl and fsl terminfo(5) capabilities to update terminal title and
automatically fill them in on terminals with the XT capability (which means
their title setting is xterm-compatible).
* Add a new option, mouse-resize-pane. When on, panes may be resized by
dragging their borders.
* Fix crash by resetting last pane on {break,swap}-pane across windows.
* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line.
* Support setting the xterm clipboard when copying from copy mode using the
xterm escape sequence for the purpose (if xterm is configured to allow it).
* Support xterm(1) cursor colour change sequences through terminfo(5) Cc
(set) and Cr (reset) extensions.
* Support DECSCUSR sequence to set the cursor style with two new terminfo(5)
extensions, Cs and Csr.
* Make the command-prompt custom prompts recognize the status-left option
character pairs.
* Add a respawn-pane command.
* Add a couple of extra xterm-style keys that gnome terminal provides.
* Allow the initial context on prompts to be set with the new -I option to
command-prompt. Include the current window and session name in the prompt
when renaming and add a new key binding ($) for rename session.
* Option bell-on-alert added to trigger the terminal bell when there is an
alert.
* Change the list-keys format so that it shows the keys using actual tmux
commands which should be able to be directly copied into the config file.
* Show full targets for lsp/lsw -a.
* Make confirm-before prompt customizable with -p option like command-prompt
and add the character pairs #W and #P to the default kill-{pane,window}
prompts.
* Avoid sending data to suspended/locked clients.
* Small memory leaks in error paths plugged.
* Vi mode improvements.
CHANGES FROM 1.3 TO 1.4, 27 December 2010
* Window bell reporting fixed.
* Show which pane is active in the list-panes output.
* Backoff reworked.
* Prevent the server from dying when switching into copy mode when already
in a different mode.
* Reset running jobs when the status line is enabled or disabled.
* Simplify xterm modifier detection.
* Avoid crashing in copy mode if the screen size is too small for the
indicator.
* Flags -n and -p added to switch-client.
* Use UTF-8 line drawing characters on UTF-8 terminals, thus fixing some
terminals (eg putty) which disable the vt100 ACS mode switching sequences
in UTF-8 mode. On terminals without ACS, use ASCII equivalents.
* New server option exit-unattached added.
* New session option destroy-unattached added.
* Fall back on normal session choice method if $TMUX exists but is invalid
rather than rejecting.
* Mark repeating keys with "(repeat)" in the key list.
* When removing a pane, don't change the active pane unless the active pane
is actually the one being removed.
* New command last-pane added.
* AIX fixes.
* Flag -a added to unbind-key.
* Add XAUTHORITY to update-environment.
* More info regarding window and pane flags is now shown in list-*.
* If VISUAL or EDITOR contains "vi" configure mode-keys and status-key to vi.
* New window option monitor-silence and session option visual-silence added.
* In the built-in layouts distribute the panes more evenly.
* Set the default value of main-pane-width to 80 instead of 81.
* Command-line flag -V added.
* Instead of keeping a per-client prompt history make it global.
* Fix rectangle copy to behave like emacs (the cursor is not part of the
selection on the right edge but on the left it is).
* Flag -l added to switch-client.
* Retrieve environment variables from the global environment rather than
getenv(3), thus allowing them to be updated during the configuration file.
* New window options other-pane-{height,width} added.
* More minor bugs fixed and manpage improvements.
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 September 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:

* 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-separated 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.
10 January 2009
* 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.
* New option, display-time, sets the time status line messages stay on screen
(unless a key is pressed). Set in milliseconds, default is 750 (0.75 seconds).
The timer is only checked every 100 ms or so.
19 June 2008
* Use "status" consistently for status line option, and prefix for "prefix" key
option.
* Allow commands to be entered at a prompt. This is triggered with the
command-prompt command, bound to : by default.
* Show status messages properly, without blocking the server.
18 June 2008
* New option, set-titles. On by default, this attempts to set the window title
using the \e]2;...\007 xterm code.
Note that elinks requires the STY environment variable (used by screen) to be
set before it will set the window title. So, if you want window titles set by
elinks, set STY before running it (any value will do). I can't do this for all
windows since setting it to an invalid value breaks screen.
* Show arrows at either end of status line when scrolled if more windows
exist. Highlight the arrow if a hidden window has activity or bell.
* Scroll the status line to show the current window if necessary. Also handle
windows smaller than needed better (show a blank status line instead of
hanging or crashing).
17 June 2008
* tmux 0.3 released.
16 June 2008
* Add some information messages when window options are changed, suggested by
Mike Erdely. Also add a -q command-line option to suppress them.
* show-window-options (showw) command.
15 June 2008
* show-options (show) command to show one or all options.
14 June 2008
* New window options: force-width and force-height. This will force a window
to an arbitrary width and height (0 for the default unlimited). This is
neat for emacs which doesn't have a sensible way to force hard wrapping at 80
columns. Also, don't try to be clever and use clr_eol when redrawing the
whole screen, it causes trouble since the redraw functions are used to draw
the blank areas too.
* Clear the blank area below windows properly when they are smaller than client,
also add an indicator line to show the vertical limit.
* Don't die on empty strings in config file, reported by Will Maier.
08 June 2008
* Set socket mode +x if any sessions are attached and -x if not.
07 June 2008
* Make status-interval actually changeable.
06 June 2008
* New window option: aggressive-resize. Normally, windows are resized to the
size of the smallest attached session to which they are linked. This means a
window only changes size when sessions are detached or attached, or they are
linked or unlinked from a session. This flag changes a window to be the size
of the smallest attached session for which it is the current window - it is
resized every time a session changes to it or away from it. This is nice for
things that handle SIGWINCH well (like irssi) and bad for things like shells.
* The server now exits when no sessions remain.
* Fix bug with inserting characters with TERM=xterm-color.
05 June 2008
* Completely reorganise command parsing. Much more common code in cmd-generic.c
and a new way of specifying windows, clients or sessions. Now, most commands
take a -t argument, which specifies a client, a session, or a window target.
Clients and sessions are given alone (sessions are fnmatch(3)d and
clients currently not), windows are give by (client|session):index. For
example, if a user is in session "1" window 0 on /dev/ttypi, these should all
be equivalent:
tmux renamew newname (current session and window)
tmux renamew -t: newname (current session and window)
tmux renamew -t:0 newname (current session, window 0)
tmux renamew -t0 newname (current session, window 0)
tmux renamew -t1:0 newname (session 1, window 0)
tmux renamew -t1: newname (session 1's current window)
tmux renamew -t/dev/ttypi newname (client /dev/ttypi's current
session and window)
tmux renamew -t/dev/ttypi: newname (client /dev/ttypi's current
session and window)
tmux renamew -t/dev/ttypi:0 newname (client /dev/ttypi's current
session, window 0)
This does have some downsides, for example, having to use -t on selectw,
tmux selectw -t7
is annoying. But then using non-flagged arguments would mean renaming the
current window would need to be something like:
tmux renamew : newname
It might be better not to try and be so consistent; comments to the usual
address ;-).
* Infrastructure for printing arguments in list-keys output. Easy ones only for
now.
04 June 2008
* Add some vi(1) key bindings in copy mode, and support binding ^[, ^\, ^]
^^ and ^_. Both from/prompted by Will Maier.
* setw monitor-activity and set status without arguments now toggle the current
value; suggested by merdely.
* New command set-window-option (alias setw) to set the single current window
option: monitor-activity to determine whether window activity is shown in
the status bar for that window (default off).
* Change so active/bell windows are inverted in status line.
* Activity monitoring - window with activity are marked in status line. No
way to disable this/filter windows yet.
* Brought select-window command into line with everything else; it now uses
-i for the window index.
* Strings to display on the left and right of the status bar may now be set
with the status-left and status-right options. These are passed through
strftime(3) before being displayed. The status bar is automatically updated
at an interval set by the status-interval option. The default is to display
nothing on the left and the date and time on the left; the default update
interval is 15 seconds.
03 June 2008
* Per session options. Setting options without specifying a session sets the
global options as normal (global options are inherited by all sessions);
passing -c or -s will set the option only for that session.
* Because a client has a session attached, any command needing a session can
take a client and use its session. So, anything that used to accept -s now
accepts -c as well.
* -s to specify session name now supports fnmatch(3) wildcards; if multiple
sessions are found, or if no -s is specified, the most newly created is used.
* If no command is specified, assume new-session. As a byproduct, clean up
command default values into separate init functions.
* kill-server command.
02 June 2008
* New command, start-server (alias "start"), to start the tmux server and do
nothing else. This is good if you have a configuration file which creates
windows or sessions (like me): in that case, starting the server the first
time tmux new is run is bad since it creates a new session and window (as
it is supposed to - starting the server is a side-effect).
Instead, I have a little script which does the equivalent of:
tmux has -s0 2>/dev/null || tmux start
tmux attach -d -s0
And I use it to start the server if necessary and attach to my primary
session.
* Basic configuration file in ~/.tmux.conf or specified with -f. This is file
contains a set of tmux commands that are run the first time the server is
started. The configuration commands are executed before any others, so
if you have a configuration file that contains:
new -d
neww -s0
And you do the following without an existing server running:
tmux new
You will end up with two sessions, session 0 with two windows (created by
the configuration file) and your client attached to session 1 with one
window (created by the command-line command). I'm not completely happy with
this, it seems a little non-obvious, but I haven't yet decided what to do
about it.
There is no environment variable handling or other special stuff yet.
In the future, it might be nice to be able to have per-session configuration
settings, probably by having conditionals in the file (so you could, for
example, have commands to define a particular window layout that would only
be invoked if you called tmux new -smysession and mysession did not already
exist).
* BIG CHANGE: -s and -c to specify session name and client name are now passed
after the command rather than before it. So, for example:
tmux -s0 neww
Becomes:
tmux neww -s0
This is to allow them to be used in the (forthcoming) configuration file
THIS WILL BREAK ANY CURRENT SCRIPTS OR ALIASES USING -s OR -c.
01 June 2008
* Bug fix: don't die if -k passed to link-window and the destination doesn't
exist.
* New command, send-keys, will send a set of keys to a window.
31 May 2008
* Fix so tmux doesn't hang if the initial window fails for some reason. This
was highlighted by problems on Darwin, thanks to Elias Pipping for the report
and access to a test account. (tmux still won't work on Darwin since its
poll(2) is broken.)
02 January 2008
* Don't attempt to reset the tty on exit if it has been closed externally.
06 December 2007
* Restore checks for required termcap entries and add a few more obvious
emulations.
* Another major reorganisation, this time of screen handling. A new set of
functions, screen_write_*, are now used to write to a screen and a tty
simultaneously. These are used by the input parser to update the base
window screen and also by the different modes which now interpose their own
screen.
30 November 2007
* Support \ek...\e\ to set window name.
27 November 2007
* Enable/disable mouse when asked, if terminal claims to support it. Mouse
sequences are just passed through unaltered for the moment.
* Big internal reorganisation. Rather than leaving control of the tty solely in
the client and piping all data through a socket to it, change so that the
server opens the tty again and reads and writes to it directly. This avoids
a lot of buffering and copying. Also reorganise the redrawing stuff so that
everything goes through screen_draw_* - this makes the code simpler, but
still needs broken up more, and all the ways of writing to screens should be
more consistent.
26 November 2007
* Rather than shifting up one line at a time once the history is full,
shift by 10% of the history each time. This is faster.
* Add ^A and ^E to copy mode to move to start-of-line/end-of-line.
24 November 2007
* Support for alt charset mode (VT100 graphics characters).
23 November 2007
* Mostly complete copy & paste. Copy mode entered with C-b [ (copy-mode
command). In copy mode, arrow keys/page up/page down/hjkl/C-u/C-f navigate,
space or C-space starts selection, and enter or C-w copies and (important!)
exits copy mode. C-b ] (paste-buffer) pastes into current window. No
extra utility keys (bol/eol/clear selection/etc), only one single buffer,
and no buffer manipulation commands (clear/view/etc) yet. The code is also
fugly :-(.
* history-limit option to set maximum history. Does not apply retroactively to
existing windows! Lines take up a variable amount of space, but a reasonable
guess for an 80-column terminal is 250 KB per 1000 lines (of history used,
an empty history takes no space).
21 November 2007
* Create every line as zero length and only expand it as data is written,
rather than creating at full size immediately.
* Make command output (eg list-keys) go to a scrollable window similar to
scroll mode.
* Redo screen redrawing so it is a) readable b) split into utility functions
that can be used outside screen.c. Use these to make scroll mode only
redraw what it has to which gets rid of irritating flickering status box and
makes it much faster.
* Full line width memory and horizontal scrolling in history.
* Initial support for scroll history. = to enter scrolling mode, and then
vi keys or up/down/pgup/pgdown to navigate. Q to exit. No horizontal history
yet (need per-line sizes) and a few kinks to be worked out (resizing while in
history mode will probably cause trouble).
20 November 2007
* Fix format string error with "must specify a client" message. Also
sprinkle some printflike tags.
* tmux 0.1 released.
17 November 2007
* (nicm) Add -k option to link-window to kill target window if it exists.
16 November 2007
* (nicm) Split in-client display into two columns. This is a hack but not a lot
more so than that bit is already and it helps with lots of keys.
* (nicm) switch-client command to switch client between different sessions. This
is pretty cool:
$ tmux bind q switch 0
$ tmux bind w switch 1
Then you can switch between sessions 0 and 1 with a key :-).
* (nicm) Accept "-c client-tty" on command line to allow client manipulation
commands, and change detach-/refresh-session to detach-/refresh-client (this
loses the -a behaviour, but at some point -session versions may return, and
-c will allow fnmatch(3)).
* (nicm) List available commands on ambiguous command.
12 November 2007
* (nicm) If the terminal supports default colours (AX present), force black
background and white foreground to default. This is useful on transparent
*terms for programs which don't do it themselves (like most(1)).
* (nicm) Fill in the rest of the man page.
* (nicm) kill-session command.
09 November 2007
* (nicm) C-space is now "^ " not "^@".
* (nicm) Support tab (\011).
* (nicm) Initial man page outline.
* (nicm) -V to show version.
* (nicm) rename-session command.
08 November 2007
* (nicm) Check for required terminal capabilities on start.
31 October 2007
* (nicm) Linux port.
30 October 2007
* (nicm) swap-window command. Same as link-window but swaps windows.
26 October 2007
* (nicm) Saving scroll region on \e7 causes problems with ncmpc so I guess
it is not required.
* (nicm) unlink-window command.
* (nicm) link-window command to link an existing window into another session
(or another index in the same session). Syntax:
tmux -s dstname link-window [-i dstidx] srcname srcidx
* (nicm) Redo window data structures. The global array remains, but each per-
session list is now a RB tree of winlink structures. This disassociates the
window index from the array size (allowing arbitrary indexes) which still
allowing windows to have multiple indexes.
25 October 2007
* (nicm) has-session command: checks if session exists.
24 October 2007
* (nicm) Support for \e6n to request cursor position. resize(1) now works.
* (nicm) Support for \e7, \e8 save/restore cursor and attribute sequences.
Currently don't save mode (probably should). Also change some cases where
out-of-bound values are ignored to limit them to within range (there are
others than need to be checked too).
23 October 2007
* (nicm) Lift limit on session name passed with -s.
* (nicm) Show size in session/window lists.
* (nicm) Pass tty up to server when client identifies and add a list-clients
command to list connected clients.
20 October 2007
* (nicm) Add default-command option and change default to be $SHELL rather than
$SHELL -l. Also try to read shell from passwd db if $SHELL isn't present.
19 October 2007
* (nicm) -n on new-session is now -s, and -n is now the initial window name.
This was documented but not implemented :-/.
* (nicm) kill-window command, bound to & by default (because it should be hard
to hit accidently).
* (nicm) bell-style option with three choices: "none" completely ignore bell;
"any" pass through a bell in any window to current; "current" ignore bells
except in current window. This applies only to the bell terminal signal,
the status bar always reflects any bells.
* (nicm) Refresh session command.
12 October 2007
* (nicm) Add a warning if $TMUX exists on new/attach.
* (nicm) send-prefix command. Bound to C-b by default.
* (nicm) set status, status-fg, status-bg commands. fg and bg are as a number
from 0 to 8 or a string ("red", "blue", etc). status may be 1/0, on/off,
yes/no.
* (nicm) Make status line mark window in yellow on bell.
04 October 2007
* (nicm) -d option to attach to detach all other clients on the same session.
* (nicm) Partial resizing support. Still buggy. A C-b S and back sometimes fixes
it when it goes wonky.
* (mxey) Added my tmux start script as an example (examples/start-tmux.sh).
* (mxey) New sessions can now be given a command for their first window.
* (mxey) Fixed usage statement for new-window.
* (nicm) attach-session (can't believe I forgot it until now!) and list-windows
commands.
* (nicm) rename-window and select-window commands.
* (nicm) set-option command (alias set): "tmux set-option prefix ^A".
* (nicm) Key binding and unbinding is back.
03 October 2007
* (nicm) {new,next,last,previous}-window.
* (nicm) Rewrite command handling so commands are much more generic and the
same commands are used for command line and keys (although most will probably
need to check how they are called). Currently incomplete (only new/detach/ls
implemented). Change: -s is now passed before command again!
* (nicm) String number arguments. So you can do: tmux bind ^Q create "blah".
* (nicm) Key binding. tmux bind key command [argument] and tmux unbind key.
Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A.
Possible commands are in cmd.c (look at cmd_bind_table).
* (nicm) Move command parsing into the client. Also rename some messages and
tidy up a few bits. Lots more tidying up needed :-/.
02 October 2007
* (nicm) Redraw client status lines on rename.
* (nicm) Error on ambiguous command.
01 October 2007
* (nicm) Restore window title handling.
* (nicm) Simple uncustomisable status line with window list.
30 September 2007
* (nicm) Window info command for debugging, C-b I.
29 September 2007
* (nicm) Deleting/inserting lines should follow scrolling region. Fix.
* (nicm) Allow creation of detached sessions: "tmux new-session -d".
* (nicm) Permit error messages to be passed back for transient clients like
rename. Also make rename -i work.
* (nicm) Pass through bell in any window to current.
28 September 2007
* (nicm) Major rewrite of input parser:
- Lose the old weirdness in favour of a state machine.
- Merge in parsing from screen.c.
- Split key parsing off into a separate file.
This is step one towards hopefully allowing a status line. It requires
that we output data as if the terminal had one line less than it really does -
a serious problem when it comes to things like scrolling. This change
consolidates all the range checking and limiting together which should make
it easier.
* (mxey) Added window renaming, like "tmux rename [-s session] [-i index] name"
27 September 2007
* Split "tmux list" into "tmux list-sessions" (ls) and "list-windows" (lsw).
* New command session selection:
- if name is specified, look for it and use it if it exists, otherwise
error
- if no name specified, try the current session from $TMUX
- if $TMUX doesn't exist, and there is only one session, use it,
otherwise error
26 September 2007
* Add command aliases, so "ls" is an alias for "list".
* Rename some commands and alter syntax to take options after a la CVS. Also
change some flags. So:
tmux -s/socket -nabc new
Becomes:
tmux -S/socket new -sabc
* Major tidy and split of client/server code.
22 September 2007
* Window list command (C-b W). Started by Maximilian Gass, finished by me.
20 September 2007
* Specify meta via environment variable (META).
* Record last window and ^L key to switch to it. Largely from Maximilian Gass.
* Reset ignored signals in child after forkpty, makes ^C work.
* Wrap on next/previous. From Maximilian Gass.
19 September 2007
* Don't renumber windows on close.
28 August 2007
* Scrolling region (\e[r) support.
27 August 2007
* Change screen.c to work more logically and hopefully fix heap corruption.
09 July 2007
* Initial import to CVS. Basic functions are working, albeit with a couple of
showstopper memory bugs and many missing features. Detaching, reattaching,
creating new sessions, listing sessions work acceptably for using with shells.
Simple curses programs (top, systat, tetris) and more complicated ones (mutt,
emacs) that don't require scrolling regions (ESC[r) mostly work fine
(including mutt, emacs). No status bar yet and no key remapping or other
customisation.
