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. $Id: CHANGES,v 1.174 2008-12-15 21:21:56 nicm Exp $ LocalWords: showw utf UTF fulvio ciriaco joshe OSC APC gettime abc DEF OA clr LocalWords: rivo nurges lscm Erdely eol smysession mysession ek dstname RB LocalWords: dstidx srcname srcidx winlink lsw nabc sabc Exp
