1.1       misho       1: CHANGES FROM 2.3 to 2.4 20 April 2017
                      2:

                      4: ====================
                      5: 
                      6: * Key tables have undergone major changes. Mode key tables are no longer
                      7:   separate from the main key tables. All mode key tables have been removed,
                      8:   together with the -t flag to bind-key and unbind-key.
                      9: 
                     10:   The emacs-edit, vi-edit, emacs-choose and vi-choose tables have been replaced
                     11:   by fixed key bindings in the command prompt and choose modes. The mode-keys
                     12:   and status-keys options remain.
                     13: 
                     14:   The emacs-copy and vi-copy tables have been replaced by the copy-mode and
                     15:   copy-mode-vi tables. Commands are sent using the -X and -N flags to
                     16:   send-keys. So the following:
                     17: 
                     18:     bind -temacs-copy C-Up scroll-up
                     19:     bind -temacs-copy -R5 WheelUpPane scroll-up
                     20: 
                     21:   Becomes:
                     22: 
                     23:     bind -Tcopy-mode C-Up send -X scroll-up
                     24:     bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
                     25: 
                     26:   This changes allows the full command parser (including command sequences) and
                     27:   command set to be used - for example, the normal command prompt with editing
                     28:   and history is now used for searching, jumping, and so on instead of a custom
                     29:   one. The default C-r binding is now:
                     30: 
                     31:     bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
                     32: 
                     33:   There are also some new commmands available with send -X, such as
                     34:   copy-pipe-and-cancel.
                     35: * set-remain-on-exit has gone -- can be achieved with hooks instead.
                     36: * Hooks: before hooks have been removed and only a selection of commands now
                     37:   have after hooks (they are no longer automatic). Additional hooks have been
                     38:   added.
                     39: * The xterm-keys option now defaults to on.

                     47:   additionally, the number of search results is displayed. The highlighting
                     48:   updates interactively with the default emacs key bindings (incremental
                     49:   search).
                     50: * source-file now understands glob patterns.
                     51: * Formats now have simple comparisons:

                     60:   - #{client_name} -- the name of a client;
                     61:   - #{client_written} -- the number of bytes written to the client.
                     62: 
                     63: * The configuration file now accepts %if/%endif conditional blocks which are
                     64:   processed when it is parsed; the argument is a format string (useful with the
                     65:   new format comparison options).
                     66: * detach-client now has -E to execute a command replacing the client instead of
                     67:   exiting.
                     68: * Add support for custom command aliases, this is an array option which
                     69:   contains items of the form "alias=command". This is consulted when an
                     70:   unknown command is parsed.
                     71: * break-pane now has -n to specify the new window name.
                     72: * OSC 52 support has been added for programs inside tmux to set a tmux buffer.
                     73: * The mouse "all event" mode (1003) is now supported.
                     74: * Palette setting is now possible (OSC 4 and 104).
                     75: * Strikethrough support (a recent terminfo is required).
                     76: * Grouped sessions can now be named (new -t).
                     77: * terminal-overrides and update-environment are now array options (the previous
                     78:   set -ag syntax should work without change).
                     79: * There have been substantial performance improvements.
                     80:

                    207:   can then be used with commands which understand src-pane specifiers
                    208:   automatically.

                    230:   has been removed, and like other commands, they now produce nothing on
                    231:   success.
                    232: 
                    233: Normal Changes
                    234: ==============
                    235: 
                    236: * tmux can now write an entry to utmp if the library 'utempter' is present
                    237:   at compile time.
                    238: * set-buffer learned append mode (-a), and a corresponding
                    239:   'append-selection' command has been added to copy-mode.
                    240: * choose-mode now has the following commands which can be bound:
                    241:        - start-of-list
                    242:        - end-of-list
                    243:        - top-line
                    244:        - bottom-line
                    245: 
                    246: * choose-buffer now understands UTF-8.
                    247: * Pane navigation has changed:
                    248:        - The old way of always using the top or left if the choice is ambiguous.
                    249:        - The new way of remembering the last used pane is annoying if the
                    250:          layout is balanced and the leftmost is obvious to the user (because
                    251:          clearly if we go right from the top-left in a tiled set of four we want
                    252:          to end up in top-right, even if we were last using the bottom-right).
                    253: 
                    254:       So instead, use a combination of both: if there is only one possible
                    255:       pane alongside the current pane, move to it, otherwise choose the most
                    256:       recently used of the choice.
                    257: * 'set-buffer' can now be told to give names to buffers.
                    258: * The 'new-session', 'new-window', 'split-window', and 'respawn-pane' commands
                    259:   now understand multiple arguments and handle quoting problems correctly.
                    260: * 'capture-pane' understands '-S-' to mean the start of the pane, and '-E-' to
                    261:   mean the end of the pane.
                    262: * Support for function keys beyond F12 has changed.  The following explains:
                    263:        - F13-F24 are S-F1 to S-F12
                    264:        - F25-F36 are C-F1 to C-F12
                    265:        - F37-F48 are C-S-F1 to C-S-F12
                    266:        - F49-F60 are M-F1 to M-F12
                    267:        - F61-F63 are M-S-F1 to M-S-F3
                    268: 
                    269:  Therefore, F13 becomes a binding of S-F1, etc.
                    270: * Support using pane id as part of session or window specifier (so % means
                    271:   session-of-%1 or window-of-%1) and window id as part of session
                    272:   (so @1 means session-of-@1).
                    273: * 'copy-pipe' command now understands formats via -F
                    274: * 'if-shell'  command now understands formats via -F
                    275: * 'split-window' and 'join-window' understand -b to create the pane to the left
                    276:   or above the target pane.
                    277:

                    280: NOTE:  This is a bug-fix release to address some important bugs which just

                    290: 
                    291: NOTE:  This release has bumped the tmux protocol version.  It is therefore
                    292: advised that the prior tmux server is restarted when this version of tmux is
                    293: installed, to avoid protocol mismatch errors for newer clients trying to
                    294: talk to an older running tmux server.
                    295:

                    302:   $PWD', the previous value of '' which meant current path of the pane can
                    303:   be specified as:  'neww -c "#{pane_current_path}"'
                    304:

                    309:   deprecated and replaced with longer-named equivalents, as listed in the
                    310:   FORMATS section of the tmux manpage.
                    311: * The various foo-{fg,bg,attr} commands have been deprecated and replaced
                    312:   with equivalent foo-style option instead.  Currently this is still
                    313:   backwards-compatible, but will be removed over time.
                    314:

                    321: * A #{pane_synchronized} format specifier has been added to be a conditional
                    322:   format if a pane is in a synchronised mode (c.f. synchronize-panes)
                    323: * Tmux now runs under Cygwin natively.
                    324: * Formats can now be nested within each other and expanded accordingly.
                    325: * Added 'automatic-rename-format' option to allow the automatic rename
                    326:   mechanism to use something other than the default of
                    327:   #{pane_current_command}.
                    328: * new-session learnt '-c' to specify the starting directory for that session
                    329:   and all subsequent windows therein.
                    330: * The session name is now shown in the message printed to the terminal when

                    336: * attach-session and switch-client learnt the '-t' option to accept a window
                    337:   and/or a pane to use.
                    338: * Copy-mode is only exited if no selection is in progress.
                    339: * Paste key in copy-mode is now possible to enter text from the clipboard.

                    426:   the pane every 100 milliseconds instead of making each change as it
                    427:   comes. Two configuration options - c0-change-trigger and
                    428:   c0-change-interval.
                    429: * find-window learns new flags:  "-C", "-N", "-T" to match against either or
                    430:   all of a window's content, name, or title.  Defaults to all three options
                    431:   if none specified.

                    443:   a session when a window is closed.  (see "move-window -r").

                    463:   list-{panes,windows,sessions}. This allows more descriptive replacements
                    464:   (such as #{session_name}) and conditionals.

                    481:   of the process in the active pane. If that fails, the directory where the

                    491:   activity) added. Therefore, remove the superfluous options
                    492:   window-status-alert-{attr,bg,fg}.

                    531: * Simplify the way jobs work and drop the persist type, so all jobs are
                    532:   fire-and-forget.

                    761:   current window, but where the linked windows are synchronized (ie creating,
                    762:   killing windows are mirrored between the sessions). A grouped session may be

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

                    842: * Improved window resizing behaviour, modelled after xterm.
                    843: * Some code reduction and a number of miscellaneous bug fixes.

                    846: 
                    847: On 01 June 2009, tmux was imported into the OpenBSD base system. From this date
                    848: onward changes are logged as part of the normal CVS commit message to either
                    849: OpenBSD or SourceForge CVS. This file will be updated to contain a summary of
                    850: major changes with each release, and to mention important configuration or
                    851: command syntax changes during development.
                    852:

                    857: 21 May 2009
                    858: 
                    859: * stat(2) files before trying to load them to avoid problems, for example
                    860:   with "source-file /dev/zero".
                    861: 
                    862: 19 May 2009
                    863: 
                    864: * Try to guess if the window is UTF-8 by outputting a three-byte UTF-8 wide
                    865:   character and seeing how much the cursor moves. Currently tries to figure out
                    866:   if this works by some stupid checks on the terminal, these need to be
                    867:   rethought. Also might be better using a width 1 character rather than width 2.
                    868: * If LANG contains "UTF-8", assume the terminal supports UTF-8, on the grounds
                    869:   that anyone who configures it probably wants UTF-8. Not certain if this is
                    870:   a perfect idea but let's see if it causes any problems.
                    871: * New window option: monitor-content. Searches for a string in a window and if
                    872:   it matches, highlight the status line.
                    873: 
                    874: 18 May 2009
                    875: 
                    876: * main-horizontal layout and main-pane-height option to match vertical.
                    877: * New window option main-pane-width to set the width of the large left pane with
                    878:   main-vertical (was left-vertical) layout. 
                    879: * Lots of layout cleanup. manual layout is now manual-vertical.
                    880: 
                    881: 16 May 2009
                    882: 
                    883: * select-layout command and a few default key bindings (M-0, M-1, M-2, M-9) to
                    884:   select layouts.
                    885: * Recreate server socket on SIGUSR1, per SF feature request 2792533.
                    886: 
                    887: 14 May 2009
                    888: 
                    889: * Keys in status line (p in vi mode, M-y in emacs) to paste the first line
                    890:   of the upper paste buffer. Suggested by Dan Colish.
                    891: * clear-history command to clear a pane's history.
                    892: * Don't force wrapping with \n when asked, let the cursor code figure it out.
                    893:   Should fix terminals which use this to detect line breaks.
                    894: * Major cleanup and restructuring of build infrastructure. Still separate files
                    895:   for GNU and BSD make, but they are now hugely simplified at the expense of
                    896:   adding a configure script which must be run before make. Now build and
                    897:   install with:
                    898: 
                    899:        $ ./configure && make && sudo make install
                    900: 
                    901: 04 May 2009
                    902: 
                    903: * Use ACS line drawing characters for pane separator lines.
                    904: 
                    905: 30 April 2009
                    906: 
                    907: * Support command sequences without a space before the semicolon, for example
                    908:   "neww; neww" now works as well as "neww ; neww". "neww;neww" is still an
                    909:   error.
                    910: * previous-layout command.
                    911: * Display the layout name in window lists.
                    912: * Merge resize-pane-up and resize-pane-down into resize-pane with -U and -D
                    913:   flags.
                    914: 
                    915: 29 April 2009
                    916: 
                    917: * Get rid of compat/vis.* - only one function was used which is easily
                    918:   replaced,and less compat code == good.
                    919: 
                    920: 27 April 2009
                    921: 
                    922: * Avoid using the prompt history when the server is locked, and prevent any
                    923:   input entered from being added to the client's prompt history.
                    924: * New command, confirm-before (alias confirm), which asks for confirmation
                    925:   before executing a command. Bound "&" and "x" by default to confirm-before
                    926:   "kill-window" and confirm-before "kill-pane", respectively.
                    927: 
                    928: 23 April 2009
                    929: 
                    930: * Support NEL, yet another way of making newline. Fixes the output from some
                    931:   Gentoo packaging thing. Reported by someone on SF then logs that allowed a
                    932:   fix sent by tcunha.
                    933: * Use the xenl terminfo flag to detect early-wrap terminals like the FreeBSD
                    934:   console. Many thanks for a very informative email from Christian Weisgerber.
                    935: 
                    936: 21 April 2009
                    937: 
                    938: * tmux 0.8 released.
                    939: 
                    940: 17 April 2009
                    941: 
                    942: * Remove the right number of characters from the buffer when escape then
                    943:   a cursor key (or other key prefixed by \033) is pressed. Reported by
                    944:   Stuart Henderson.
                    945: 
                    946: 03 April 2009
                    947: 
                    948: * rotate-window command. -U flag (default) for up, -D flag for down.
                    949: 
                    950: 02 April 2009
                    951: 
                    952: * Change scroll/pane redraws to only redraw the single pane affected rather
                    953:   than the entire window.
                    954: * If redrawing the region would mean redrawing > half the pane, just schedule
                    955:   to redraw the entire window. Also add a flag to skip updating the window any
                    956:   further if it is scheduled to be redrawn. This has the effect of batching
                    957:   multiple redraws together.
                    958: 
                    959: 01 April 2009
                    960: 
                    961: * Basic horizontal splitting and layout management. Still some redraw and other
                    962:   issues - particularly, don't mix with manual pane resizing, be careful when
                    963:   viewing from multiple clients and don't expect shell windows to redraw very
                    964:   well after the layout is changed; generally cycling the layout a few times
                    965:   will fix most problems. Getting this in for testing while I think about how
                    966:   to deal with manual mode.
                    967: 
                    968:   Split window as normal and cycle the layouts with C-b space. Some of the
                    969:   layouts will work better when swap-pane comes along.
                    970: 
                    971: 31 March 2009
                    972: 
                    973: * AIX port, thanks to cmihai for access to a box. Only tested on 6.1 with xlc
                    974:   10.1 (make sure CC is set). Needs GNU make and probably ncurses (didn't try
                    975:   plain curses). Also won't build with DEBUG, so comment the FDEBUG=1 line in
                    976:   GNUmakefile.
                    977: * Draw a vertical line on the right when the window size is less than the
                    978:   terminal size. This is partly to shake out any horizontal limit bugs on the
                    979:   way to horizontal splitting/pane tiling. Currently a bit slow since it has to
                    980:   do a lot of redrawing but hopefully that will improve as I get some better
                    981:   ideas for how to do it.
                    982: * Fix remaining problems with copy and paste and UTF-8.
                    983: 
                    984: 28 March 2009
                    985: 
                    986: * Better UTF-8 support, including combined characters. Unicode data is now
                    987:   stored as UTF-8 in a separate array, the code does a lookup into this every
                    988:   time it gets to a UTF-8 cell. Zero width characters are just appended onto
                    989:   the UTF-8 data for the previous cell. This also means that almost no bytes
                    990:   extra are wasted non-Unicode data (yay).
                    991: 
                    992:   Still some oddities, such as copy mode skips over wide characters in a
                    993:   strange way, and the code could do with some tidying.
                    994: * Key repeating is now a property of the key binding not of the command.
                    995:   Repeat is turned on when the key is bound with the -r flag to bind-key.
                    996:   next/previous-window no longer repeat by default as it turned out to annoy
                    997:   me.
                    998: 
                    999: 27 March 2009
                   1000: 
                   1001: * Clear using ED when redrawing the screen. I foolishly assumed using spaces
                   1002:   would be equivalent and terminals would pick up on this, but apparently not.
                   1003:   This fixes copy and paste in xterm/rxvt.
                   1004: * Sockets in /tmp are now created in a subdirectory named, tmux-UID, eg
                   1005:   tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a
                   1006:   separate server, the new -L command line option should be used: this creates
                   1007:   a socket in the same directory with a different name ("-L main" will create
                   1008:   socket called "main"). -S should only be used to place the socket outside
                   1009:   /tmp. This makes sockets a little more secure and a bit more convenient to
                   1010:   use multiple servers.
                   1011: 
                   1012: 21 March 2009
                   1013: 
                   1014: * New session flag "set-remain-on-exit" to set remain-on-exit flag for new
                   1015:   windows created in that session (like "remain-by-default" used to do). Not
                   1016:   perfectly happy about this, but until I can think of a good way to introduce
                   1017:   it generically (maybe a set of options in the session) this will do. Fixes
                   1018:   SF request 2527847.
                   1019: 
                   1020: 07 March 2009
                   1021: 
                   1022: * Support for 88 colour terminals.
                   1023: * break-pane command to create a new window using an existing pane.
                   1024: 
                   1025: 02 March 2009
                   1026: 
                   1027: * Make escape key timer work properly so escape+key can be used without
                   1028:   lightning fast key presses.
                   1029: 
                   1030: 13 February 2009
                   1031: 
                   1032: * Redo mode keys slightly more cleanly and apply them to command prompt
                   1033:   editing. vi or emacs mode is controlled by the session option status-keys.
                   1034: 
                   1035: 12 February 2009
                   1036: 
                   1037: * Looking up argv[0] is expensive, so just use p_comm for the window name which
                   1038:   is good enough. Also increase name update time to 500 ms.
                   1039: 
                   1040: 11 February 2009
                   1041: 
                   1042: * Only use ri when actually at the top of the screen; just move the cursor up
                   1043:   otherwise.
                   1044: * FreeBSD's console wraps lines at $COLUMNS - 1 rather than $COLUMNS (the
                   1045:   cursor can never be beyond $COLUMNS - 1) and does not appear to support
                   1046:   changing this behaviour, or any of the obvious possibilities (turning off
                   1047:   right margin wrapping, insert mode). This is irritating, most notably because
                   1048:   it impossible to write to the very bottom-right of the screen without
                   1049:   scrolling. To work around this, if built on FreeBSD and run with a "cons"
                   1050:   $TERM, the bottom-right cell on the screen is omitted.
                   1051: * Emulate scroll regions (slowly) to support the few terminals which don't have
                   1052:   it (some of which don't really have any excuse).
                   1053: 
                   1054: 10 February 2009
                   1055: 
                   1056: * No longer redraw the status line every status-interval unless it has actually
                   1057:   changed.
                   1058:

                   1061: * Don't treat empty arguments ("") differently when parsing configuration
                   1062:   file/command prompt rather than command line.
                   1063: * tmux 0.7 released.
                   1064: 
                   1065: 03 February 2009
                   1066: 
                   1067: * New command, copy-buffer (alias copyb), to copy a session paste buffer to
                   1068:   another session.
                   1069: 
                   1070: 01 February 2009
                   1071: 
                   1072: * The character pair #(command) may now contain (escaped) right parenthesis.
                   1073: 
                   1074: 30 January 2009
                   1075: 
                   1076: * . now bound to "command-prompt 'move-window %%'" by default, from joshe.
                   1077: 
                   1078: 29 January 2009
                   1079: 
                   1080: * Window options to set status line fg, bg and attributes for a single
                   1081:   window. Options are: window-status-fg, window-status-bg,
                   1082:   window-status-attr. Set to "default" to use the session status colours.
                   1083: 
                   1084:   This allows quite neat things like:
                   1085: 
                   1086:        $ cat ~/bin/xssh
                   1087:        #!/bin/sh
                   1088: 
                   1089:        if [ ! -z "$TMUX" ]; then
                   1090:        case "$1" in

                   1096:                ;;
                   1097:        esac

                   1102: 
                   1103: * Support #(command) in status-left, and status-right, which is displayed as
                   1104:   the first line of command's output (e.g. set -g status-right
                   1105:   "#(whoami)@#(hostname -s)"). Commands with )s aren't supported.
                   1106: 
                   1107: 28 January 2009
                   1108: 
                   1109: * Support mouse in copy mode to move cursor. Can't do anything else at the
                   1110:   moment until other mouse modes are handled.
                   1111: * Better support for at least the most common variant of mouse input: parse it
                   1112:   and adjust for different panes. Also support mouse in window/session choice
                   1113:   mode.
                   1114: 
                   1115: 27 January 2009
                   1116: 
                   1117: * Bring back the fancy window titles with session/window names: it is easy to
                   1118:   work around problems with elinks (see FAQ).
                   1119: * -u flag to scroll-mode and copy-mode to start scrolled one page
                   1120:   up. scroll-mode -u is bound to prefix,page-up (ppage) by default.
                   1121: * Allow status, mode and message attributes to be changed by three new options:
                   1122:   status-attr, mode-attr, message-attr. A comma-separated list is accepted
                   1123:   containing: bright, dim, underscore, blink, reverse, hidden, italics, for
                   1124:   example:
                   1125: 
                   1126:        set -g status-attr bright,blink
                   1127: 
                   1128:   From Josh Elsasser, thanks!
                   1129: 
                   1130: 26 January 2009
                   1131: 
                   1132: * Be more clever about picking the right process to create the window name.
                   1133: * Don't balls up the terminal on UTF-8 combined characters. Don't support them
                   1134:   properly either - they are just discarded for the moment.
                   1135: 
                   1136: 25 January 2009
                   1137: 
                   1138: * load-buffer command
                   1139: 
                   1140: 23 January 2009
                   1141: 
                   1142: * Use reverse colours rather than swapping fg and bg for message, mode and
                   1143:   status line. This makes these usable on black and white terminals.
                   1144: * Better error messages when creating a session or window fails.
                   1145: * Oops. Return non-zero on error. Reported by Will Maier.
                   1146: 
                   1147: 21 January 2009
                   1148: 
                   1149: * Handle SIGTERM (and kill-server which uses it), a bit more neatly - tidy
                   1150:   up properly and print a nicer message. Same effect though :-).
                   1151: * new-window now supports -k to kill target window if it exists.
                   1152: * Bring back split-window -p and -l options to specify the height a percentage
                   1153:   or as a number of lines.
                   1154: * Make window and session choice modes allow you to choose items in vi keys
                   1155:   mode (doh!). As a side-effect, this makes enter copy selection (as well
                   1156:   as C-w/M-w) when using emacs keys in copy mode. Reported by merdely.
                   1157: 
                   1158: 20 January 2009
                   1159: 
                   1160: * Darwin support for automatic-rename from joshe; Darwin doesn't seem to have
                   1161:   a sane method of getting argv[0] and searching for the precise insane way
                   1162:   is too frustrating, so this just uses the executable name.
                   1163: * Try to change the window title to match the command running it in. This is
                   1164:   done by reading argv[0] from the process group leader of the group that owns
                   1165:   the tty (tcgetpgrp()). This can't be done portably so some OS-dependent code
                   1166:   is introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment.
                   1167: 
                   1168:   A new window flag, automatic-rename, is available: if this is set to off, the
                   1169:   window name is not changed. Specifying a name with the new-window,
                   1170:   new-session or rename-window commands will automatically set this flag to off
                   1171:   for the window in question. To disable it entirely set the option to off
                   1172:   globally (setw -g automatic-rename off).
                   1173: 
                   1174: 19 January 2009
                   1175: 
                   1176: * Fix various stupid issues when the status line is turned off. Grr.
                   1177: * Use reverse attributes for clock and cursor, otherwise they do not
                   1178:   appear on black and white terminals.
                   1179: * An error in a command sequence now stops execution of that sequence.
                   1180:   Internally, each command code now passes a return code back rather than
                   1181:   talking to the calling client (if any) directly.
                   1182: * attach-session now tries to start the server if it isn't already started - if
                   1183:   no sessions are created in .tmux.conf this will cause an error.
                   1184: * Clean up starting server by making initial client get a special socketpair.
                   1185: 
                   1186: 18 January 2009
                   1187: 
                   1188: * Unbreak UTF-8.
                   1189: * -a flag to next-window and previous-window to select the next or previous
                   1190:   window with activity or bell. Bound to M-n and M-p.
                   1191: * find-window command to search window names, titles and visible content (but
                   1192:   not history) for a string. If only one is found, the window is selected
                   1193:   otherwise a choice list is shown. This (as with the other choice commands)
                   1194:   only works from a key. Bound to "f" by default.
                   1195: * Cleaned up command printing code, also enclose arguments with spaces in "s.
                   1196: * Added command sequences. These are entered by separating each argument by a ;
                   1197:   argument (spaces on both sides), for example:
                   1198: 
                   1199:        lsk ; lsc
                   1200: 
                   1201:   To use a literal ; as the argument prefix it with \, for example:
                   1202: 
                   1203:        bind x lsk \; lsc
                   1204: 
                   1205:   Commands are executed from left to right. Also note that command sequences do
                   1206:   not support repeat-time repetition unless all commands making up the sequence
                   1207:   support it.
                   1208: * suspend-client command to suspend a client. Don't try to background it
                   1209:   though...
                   1210: * Mark attached sessions in sessions lists. Suggested by Simon Kuhnle.
                   1211: 
                   1212: 17 January 2009
                   1213: 
                   1214: * tmux 0.6 released.
                   1215: 
                   1216: 15 January 2009
                   1217: 
                   1218: * Support #H for hostname and #S for session name in status-left/right.
                   1219: * Two new commands, choose-window and choose-session which work only when bound
                   1220:   to a key and allow the window or session to be selected from a list. These
                   1221:   are now bound to "w" and "s" instead of the list commands.
                   1222: 
                   1223: 14 January 2009
                   1224: 
                   1225: * Rework the prefix-time stuff. The option is now called repeat-time and
                   1226:   defaults to 500 ms. It only applies to a small subset of commands, currently:
                   1227:   up-pane, down-pane, next-window, previous-window, resize-pane-up,
                   1228:   resize-pane-down. These are the commands for which it is obviously useful,
                   1229:   having it for everything else was just bloody annoying.
                   1230: * The alt-up and alt-down keys now resize a pane by five lines at a time.
                   1231: * switch-pane is now select-pane and requires -p to select a pane. The
                   1232:   "o" key binding is changed to down-pane.
                   1233: * up-pane and down-pane commands, bound to arrow up and down by default.
                   1234: * Multiple vertical window splitting. Minimum pane size is four lines, an
                   1235:   (unhelpful) error will be shown if attempting to split a window with less
                   1236:   that eight lines. If the window is resized, as many panes are shown as can
                   1237:   fit without reducing them below four lines. There is (currently!) not a way
                   1238:   to show a hidden pane without making the window larger.
                   1239: 
                   1240:   Note the -p and -l options to split-window are now gone, these may reappear
                   1241:   once I think them through again.
                   1242: * Server locking on inactivity (lock-after-time) is now disabled by default.
                   1243: 
                   1244: 13 January 2009
                   1245: 
                   1246: * kill-pane command.
                   1247: 
                   1248: 12 January 2009
                   1249: 
                   1250: * command-prompt now accepts a single argument, a template string. Any
                   1251:   occurrences of %% in this string are replaced by whatever is entered at the
                   1252:   prompt and the result is executed as a command. This allows things like (now
                   1253:   bound by default):
                   1254: 
                   1255:         bind , command-prompt "rename-window %%"
                   1256: 
                   1257:   Or my favourite:
                   1258: 
                   1259:          bind x command-prompt "split-window 'man %%'"
                   1260: 
                   1261: * Option to set prefix time, allowing multiple commands to be entered without
                   1262:   pressing the prefix key again, so long as they each typed within this time of
                   1263:   each other.
                   1264: * Yet more hacks for key handling. Think it is just about working now.
                   1265: * Two commands, resize-pane-up and resize-pane-down to resize a pane.
                   1266: * Make the window pane code handle panes of different sizes, and add a -l
                   1267:   and -p arguments to split-window to specify the new window size in lines
                   1268:   or as a percentage.
                   1269: 
                   1270: 11 January 2009
                   1271: 
                   1272: * Vertical window splitting. Currently can only split a window into two panes.
                   1273:   New split-window command splits (bound to ") and switch-pane command (bound to
                   1274:   o) switches between panes.
                   1275: 
                   1276:   close-pane, swap-pane commands are to follow. Also to come are pane resizing,
                   1277:   >2 panes, the ability to break a pane out to a full window and vice versa and
                   1278:   possibly horizontal splitting.
                   1279: 
                   1280:   Panes are subelements of windows rather than being windows in their own
                   1281:   right. I tried to make them windows (so the splitting was at the session or
                   1282:   client level) but this rapidly became very complex and invasive. So in the
                   1283:   interests of having something working, I just made it so each window can have
                   1284:   two child processes instead of one (and it still took me 12 hours straight
                   1285:   coding). Now the concept is proven and much of the support code is there,
                   1286:   this may change in future if more flexibility is needed.
                   1287: * save-buffer command, from Tiago Cunha.
                   1288: 
                   1289: 10 January 2009
                   1290: 
                   1291: * New option, lock-after-time. If there is no activity in the period specified
                   1292:   by this option (in seconds), tmux will lock the server. Default is 1800 (30
                   1293:   minutes), set to 0 to disable.
                   1294: * Server locking. Two new commands: set-password to set a password (a
                   1295:   preencrypted password may be specified with -c); and lock-server to lock the
                   1296:   server until the password is entered. Also an additional command line flag,
                   1297:   -U, to unlock from the shell. The default password is blank (any password
                   1298:   accepted). If specifying an encrypted password from encrypt(1) in .tmux.conf
                   1299:   with -c, don't forget to enclose it in single-quotes (') to prevent shell
                   1300:   variable expansion.
                   1301: * If a window is created from the command line, tmux will now use the same
                   1302:   current working directory for the new process. A new default-path option to
                   1303:   sets the working directory for processes created from keys or interactively
                   1304:   from the prompt.
                   1305: * New mode to display a large clock. Entered with clock-mode command (bound to
                   1306:   C-b t by default); two window options: clock-mode-colour and clock-mode-style
                   1307:   (12 or 24). This will probably be used as the basis for window locking.
                   1308: * New command, server-info, to show some server information and terminal
                   1309:   details.
                   1310: 
                   1311: 09 January 2009
                   1312: 
                   1313: * Stop using ncurses variables and instead build a table of the codes we want
                   1314:   into an array for each terminal type. This makes the code a little more
                   1315:   untidy in places but gets rid of the awful global variables and calling
                   1316:   setterm all the time, and shoves all the ncurses-dependent mess into a single
                   1317:   file, tty-term.c. It also allows overriding single terminal codes, this is
                   1318:   used to fix rxvt on some platforms (where it is missing dch) and in future
                   1319:   may allow user customisation a la vim.
                   1320: * Update key handling code. Simplify, support ctrl properly and add a new
                   1321:   window option (xterm-keys) to output xterm key codes including ctrl and,
                   1322:   if available, alt and shift.
                   1323: 
                   1324: 08 January 2009
                   1325: 
                   1326: * If built without DEBUG (the release versions), don't cause a fatal error if
                   1327:   the grid functions notice an input error, just log and ignore the
                   1328:   request. This might mean me getting shouted at less often when bugs kill
                   1329:   long-running sessions, at least in release versions.
                   1330: * Hopefully fix cursor out-of-bounds checking when writing to grid. When I
                   1331:   wrote the code I must have forgotten that the cursor can be one cell off the
                   1332:   right of the screen (yes, I know), so there were number of out-of-bounds/
                   1333:   overflow problems.
                   1334: 
                   1335: 07 January 2009
                   1336: 
                   1337: * New flag to set and setw, -u, to unset an option (allowing it to inherit from)
                   1338:   the global options again.
                   1339: * Added more info messages for options changes.
                   1340: * A bit of tidying and reorganisation of options code.
                   1341: 
                   1342: 06 January 2009
                   1343: 
                   1344: * Don't crash when backspacing if cursor is off the right of the screen,
                   1345:   reported by David Chisnall.
                   1346: * Complete words at any point inside command in prompt, also use option name
                   1347:   as well as command names.
                   1348: * Per-client prompt history of up to 100 items.
                   1349: * Use a splay tree for key bindings instead of an array. As a side-effect this
                   1350:   sorts them when listed.
                   1351: 
                   1352: 22 December 2008
                   1353: 
                   1354: * Use the right keys for home and end.
                   1355: 
                   1356: 20 December 2008
                   1357: 
                   1358: * Add vim mode for tmux configuration file to examples/, from Tiago Cunha.
                   1359: 
                   1360: 15 December 2008
                   1361: 
                   1362: * New command, source-file (alias source), to load a configuration
                   1363:   file. Written by Tiago Cunha, many thanks.
                   1364: 
                   1365: 13 December 2008
                   1366: 
                   1367: * Work around lack of dch. On Linux, the rxvt termcap doesn't have it (it is
                   1368:   lying, but we can't really start disbelieving termcaps...). This is a bit
                   1369:   horrible - I can see no way to do it without pretty much redrawing the whole
                   1370:   line, but it works...
                   1371: 
                   1372: 10 December 2008
                   1373: 
                   1374: * glibc's getopt(3) is useless: it is not POSIX compliant without jumping
                   1375:   through non-portable hoops, and the method of resetting it is unclear (the
                   1376:   man page on my system says set optind to 1, but other sources say 0). So,
                   1377:   import OpenBSD's getopt_long.c into compat/ for use on Linux and use the
                   1378:   clearly documented optreset = optind = 1 method. This fixes some strange
                   1379:   issues with command parsing (getting the syntax wrong would prevent any
                   1380:   further commands being parsed).
                   1381: 
                   1382: 06 December 2008
                   1383: 
                   1384: * Bring set/setw/show/showw into line with other commands. This means that by
                   1385:   default they now affect the current window (if any); the new -g flag must be
                   1386:   passed to set the global options. This changes the behaviour of set/show and
                   1387:   WILL BREAK CURRENT CONFIGURATIONS.
                   1388: 
                   1389:   In summary, whether in the configuration file, the command prompt, or a key
                   1390:   binding, use -g to set a global option, use -t to specify a particular window
                   1391:   or session, or omit both to try and use the current window or session.
                   1392: 
                   1393:   This makes set/show a bit of a pain but is the correct behaviour for
                   1394:   setw/showw and is the same as every other command, so we can put up with a
                   1395:   bit of pain for consistency.
                   1396: * Redo window options. They now work in the same way to session options with a
                   1397:   global options set. showw/setw commands now have similar syntax to show/set
                   1398:   (including the ability to use abbreviations).
                   1399: 
                   1400:   PLEASE NOTE this includes the following configuration-breaking changes:
                   1401: 
                   1402:   - remain-by-default is now GONE, use "setw -g remain-on-exit" to apply the
                   1403:     global window option instead;
                   1404:   - mode-keys is now a window option rather than session - use "setw [-g]
                   1405:     mode-keys" instead of set.
                   1406: 
                   1407:   There are also some additions:
                   1408: 
                   1409:   - message-fg and message-bg session options to control status line message
                   1410:     colours;
                   1411:   - mode-fg and mode-bg window options to set colours in window modes such as
                   1412:     copy mode.
                   1413: 
                   1414:   The options code still a mess and now there is twice as much of it :-(.
                   1415: 
                   1416: 02 December 2008
                   1417: 
                   1418: * Add support for including the window title in status-left or status-right
                   1419:   strings by including the character pair "#T". This may be prefixed with
                   1420:   a number to specify a maximum length, for example "#24T" to use at most
                   1421:   24 characters of the title.
                   1422: * Introduce two new options, status-left-length and status-right-length,
                   1423:   control the maximum length of left and right components of the status bar.
                   1424: * elinks (and possibly others) bypass the terminal and talk directly to X to
                   1425:   restore the window title when exiting. tmux can't know about this particular
                   1426:   bit of stupidity so the title ends up strange - the prefix isn't terribly
                   1427:   important and elinks is quite useful so just get rid of it.
                   1428: 
                   1429: 27 November 2008
                   1430: 
                   1431: * Tweaks to support Dragonfly.
                   1432: 
                   1433: 17 November 2008
                   1434: 
                   1435: * tmux 0.5 released.
                   1436: 
                   1437: 16 November 2008
                   1438: 
                   1439: * New window option: "utf8"; this must be on (it is off by default) for UTF-8
                   1440:   to be parsed. The global/session option "utf8-default" controls the setting
                   1441:   for new windows.
                   1442: 
                   1443:   This means that by default tmux does not handle UTF-8. To use UTF-8 by
                   1444:   default it is necessary to a) "set utf8-default on" in .tmux.conf b) start
                   1445:   tmux with -u on any terminal which support UTF-8.
                   1446: 
                   1447:   It seems a bit unnecessary for this to be a per-window option but that is
                   1448:   the easiest way to do it, and it can't do any harm...
                   1449: * Enable default colours if op contains \033[39;49m, based on a report from
                   1450:   fulvio ciriaco.
                   1451: 
                   1452: 12 November 2008
                   1453: 
                   1454: * Keep stack of last windows rather than just most recent; based on a diff from
                   1455:   joshe.
                   1456: 
                   1457: 04 November 2008
                   1458: 
                   1459: * Don't try to redraw status line when showing a prompt or message; if it does,
                   1460:   the status timer is never reset so it redraws on every loop. Spotted by
                   1461:   joshe.
                   1462: 
                   1463: 09 October 2008
                   1464: 
                   1465: * Translate 256 colours into 16 if 256 is not available, same as screen does.
                   1466: * Better support for OSC command (only to set window title now), and also
                   1467:   support using APC for the same purpose (some Linux default shell profiles do
                   1468:   this).
                   1469: 
                   1470: 25 September 2008
                   1471: 
                   1472: * Large internal rewrite to better support 256 colours and UTF-8. Screen data
                   1473:   is now stored as single two-way array of structures rather than as multiple
                   1474:   separate arrays. Also simplified a lot of code.
                   1475: 
                   1476:   Only external changes are three new flags, -2, -d and -u, which force tmux to
                   1477:   assume the terminal supports 256 colours, default colours (useful for
                   1478:   xterm-256color which lacks the AX flag), or UTF-8 respectively.
                   1479: 
                   1480: 10 September 2008
                   1481: 
                   1482: * Split off colour conversion code from screen code.
                   1483: 
                   1484: 09 September 2008
                   1485: 
                   1486: * Initial UTF-8 support. A bit ugly and with a limit of 4096 UTF-8
                   1487:   characters per window.
                   1488: 
                   1489: 08 September 2008
                   1490: 
                   1491: * 256 colour support. tmux attempts to autodetect the terminal by looking
                   1492:   both at what ncurses reports (usually wrong for xterm) and checking if
                   1493:   the TERM contains "256col". For xterm TERM=xterm-256color is needed (as
                   1494:   well as a build that support 256 colours); this seems to work for rxvt
                   1495:   as well. On non-256 colour terminals, high colours are translated to white
                   1496:   foreground and black background.
                   1497: 
                   1498: 28 August 2008
                   1499: 
                   1500: * Support OS X/Darwin thanks to bsd-poll.c from OpenSSH. Also convert
                   1501:   from clock_gettime(2) to gettimeofday(2) as OS X doesn't support the
                   1502:   former; microsecond accuracy will have to be sufficient ;-).
                   1503: 
                   1504: 07 August 2008
                   1505: 
                   1506: * Lose some unused/useless wrapper functions.
                   1507: 
                   1508: 25 July 2008
                   1509: 
                   1510: * Shell variables may now be defined and used in configuration file. Define
                   1511:   variables with:
                   1512: 
                   1513:        VAR=1
                   1514: 
                   1515:   And use with:
                   1516: 
                   1517:         renamew ${VAR}
                   1518:        renamew "x${VAR}x"
                   1519: 
                   1520:  Also some other fixes to make, for example, "abc""abc" work similarly to
                   1521:  the shell.
                   1522: 
                   1523: 24 July 2008
                   1524: 
                   1525: * Finally lose inconsistently-used SCREEN_DEF* defines.
                   1526: * If cursor mode is on, switch the arrow keys from \033[A to \033OA.
                   1527: * Support the numeric keypad in both application and numbers mode. This is
                   1528:   different from screen which always keeps it in application mode.
                   1529: 
                   1530: 19 July 2008
                   1531: 
                   1532: * Unbreak "set status" - tmux thought it was ambiguous, reported by rivo nurges.
                   1533: 
                   1534: 02 July 2008
                   1535: 
                   1536: * Split vi and emacs mode keys into two tables and add an option (mode-keys)
                   1537:   to select between them. Default is emacs, use,
                   1538: 
                   1539:      tmux set mode-keys vi
                   1540: 
                   1541:   to change to vi.
                   1542: 
                   1543:   vi mode uses space to start selection, enter to copy selection and escape
                   1544:   to clear selection.
                   1545: 
                   1546: 01 July 2008
                   1547: 
                   1548: * Protocol versioning. Clients which identify as a different version from the
                   1549:   server will be rejected.
                   1550: * tmux 0.4 released.
                   1551: 
                   1552: 29 June 2008
                   1553: 
                   1554: * Zombie windows. These are not closed when the child process dies. May be
                   1555:   set for a window with the new "remain-on-exit" option; the default setting
                   1556:   of this flag for new windows may be set with the "remain-by-default" session
                   1557:   option.
                   1558: 
                   1559:   A window may be restarted with the respawn-window command:
                   1560: 
                   1561:        respawn-window [-k] [command]
                   1562: 
                   1563:   If -k is given, any existing process running in the window is killed;
                   1564:   if command is omitted, the same command as when the window was first
                   1565:   created is used.
                   1566: 
                   1567: 27 June 2008
                   1568: 
                   1569: * Handle nonexistent session or client to -t properly.
                   1570: 
                   1571: 25 June 2008
                   1572: 
                   1573: * select-prompt command to allow a window to be selected at a prompt. Only
                   1574:   windows in the current session may be selected. Bound to ' by default.
                   1575:   Suggested by merdely.
                   1576: * move-window command. Requested by merdely.
                   1577: * Support binding alt keys (prefixed with M-). Change default to use
                   1578:   C- for ctrl keys (^ is still accepted as an alternative).
                   1579: * Slim down default key bindings: support lowercase only.
                   1580: * Handle escaped keys properly (parse eg \033b into a single key code) and
                   1581:   use this to change copy mode next/previous work to M-f and M-b to match
                   1582:   emacs.
                   1583: 
                   1584: 24 June 2008
                   1585: 
                   1586: * Next word (C-n/w) and previous word (C-b/b) in copy mode.
                   1587: 
                   1588: 23 June 2008
                   1589: 
                   1590: * list-commands command (alias lscm).
                   1591: * Split information about options into a table and use it to parse options
                   1592:   on input (allowing abbreviations) and to print them with show-options
                   1593:   (meaning that bell-action gets a proper string). This turned out a bit ugly
                   1594:   though :-/.
                   1595: 
                   1596: 22 June 2008
                   1597: 
                   1598: * Do not translate black and white into default if the terminal supports
                   1599:   default colours. This was nice to force programs which didn't use default
                   1600:   colours to be properly transparent in rxvt/aterm windows with a background
                   1601:   image, but it causes trouble if someone redefines the default foreground and
                   1602:   background (to have black on white or something).
                   1603: 
                   1604: 21 June 2008
                   1605: 
                   1606: * Naive tab completion in the command prompt. This only completes command
                   1607:   names if a) they are at the start of the text b) the cursor is at
                   1608:   the end of the text c) the text contains no spaces.
                   1609: * Only attempt to set the title where TERM looks like an xterm (contains
                   1610:   "xterm", "rxvt" or is "screen"). I hate this but I don't see a better way:
                   1611:   setting the title actually kills some other terminals pretty much dead.
                   1612: * Strip padding out of terminfo(5) strings. Currently the padding is just
                   1613:   ignored, this may need to be altered if there are any software terminals
                   1614:   out there that actually need it.
                   1615: 
                   1616: 20 June 2008
                   1617: 
                   1618: * buffer-limit option to set maximum size of buffer stack. Default is 9.
                   1619: * Initial buffer improvements. Each session has a stack of buffers and each
                   1620:   buffer command takes a -b option to manipulate items on the stack. If -b
                   1621:   is omitted, the top entry is used. The following commands are currently
                   1622:   available:
                   1623: 
                   1624:        set-buffer [-b index] [-t target-session] string
                   1625:        paste-buffer [-d] [-b index] [-t target-window]
                   1626:        delete-buffer [-b index] [-t target-session]
                   1627:        show-buffers [-t target-session]
                   1628:        show-buffer [-b index] [-t target-session]
                   1629: 
                   1630:   -d to paste-buffer deletes the buffer after pasting it.
                   1631: * New option, display-time, sets the time status line messages stay on screen
                   1632:   (unless a key is pressed). Set in milliseconds, default is 750 (0.75 seconds).
                   1633:   The timer is only checked every 100 ms or so.
                   1634: 
                   1635: 19 June 2008
                   1636: 
                   1637: * Use "status" consistently for status line option, and prefix for "prefix" key
                   1638:   option.
                   1639: * Allow commands to be entered at a prompt. This is triggered with the
                   1640:   command-prompt command, bound to : by default.
                   1641: * Show status messages properly, without blocking the server.
                   1642: 
                   1643: 18 June 2008
                   1644: 
                   1645: * New option, set-titles. On by default, this attempts to set the window title
                   1646:   using the \e]2;...\007 xterm code.
                   1647: 
                   1648:   Note that elinks requires the STY environment variable (used by screen) to be
                   1649:   set before it will set the window title. So, if you want window titles set by
                   1650:   elinks, set STY before running it (any value will do). I can't do this for all
                   1651:   windows since setting it to an invalid value breaks screen.
                   1652: * Show arrows at either end of status line when scrolled if more windows
                   1653:   exist. Highlight the arrow if a hidden window has activity or bell.
                   1654: * Scroll the status line to show the current window if necessary. Also handle
                   1655:   windows smaller than needed better (show a blank status line instead of
                   1656:   hanging or crashing).
                   1657: 
                   1658: 17 June 2008
                   1659: 
                   1660: * tmux 0.3 released.
                   1661: 
                   1662: 16 June 2008
                   1663: 
                   1664: * Add some information messages when window options are changed, suggested by
                   1665:   Mike Erdely. Also add a -q command-line option to suppress them.
                   1666: * show-window-options (showw) command.
                   1667: 
                   1668: 15 June 2008
                   1669: 
                   1670: * show-options (show) command to show one or all options.
                   1671: 
                   1672: 14 June 2008
                   1673: 
                   1674: * New window options: force-width and force-height. This will force a window
                   1675:   to an arbitrary width and height (0 for the default unlimited). This is
                   1676:   neat for emacs which doesn't have a sensible way to force hard wrapping at 80
                   1677:   columns. Also, don't try to be clever and use clr_eol when redrawing the
                   1678:   whole screen, it causes trouble since the redraw functions are used to draw
                   1679:   the blank areas too.
                   1680: * Clear the blank area below windows properly when they are smaller than client,
                   1681:   also add an indicator line to show the vertical limit.
                   1682: * Don't die on empty strings in config file, reported by Will Maier.
                   1683: 
                   1684: 08 June 2008
                   1685: 
                   1686: * Set socket mode +x if any sessions are attached and -x if not.
                   1687: 
                   1688: 07 June 2008
                   1689: 
                   1690: * Make status-interval actually changeable.
                   1691: 
                   1692: 06 June 2008
                   1693: 
                   1694: * New window option: aggressive-resize. Normally, windows are resized to the
                   1695:   size of the smallest attached session to which they are linked. This means a
                   1696:   window only changes size when sessions are detached or attached, or they are
                   1697:   linked or unlinked from a session. This flag changes a window to be the size
                   1698:   of the smallest attached session for which it is the current window - it is
                   1699:   resized every time a session changes to it or away from it. This is nice for
                   1700:   things that handle SIGWINCH well (like irssi) and bad for things like shells.
                   1701: * The server now exits when no sessions remain.
                   1702: * Fix bug with inserting characters with TERM=xterm-color.
                   1703: 
                   1704: 05 June 2008
                   1705: 
                   1706: * Completely reorganise command parsing. Much more common code in cmd-generic.c
                   1707:   and a new way of specifying windows, clients or sessions. Now, most commands
                   1708:   take a -t argument, which specifies a client, a session, or a window target.
                   1709:   Clients and sessions are given alone (sessions are fnmatch(3)d and
                   1710:   clients currently not), windows are give by (client|session):index. For
                   1711:   example, if a user is in session "1" window 0 on /dev/ttypi, these should all
                   1712:   be equivalent:
                   1713: 
                   1714:        tmux renamew newname                    (current session and window)
                   1715:        tmux renamew -t: newname                (current session and window)

                   1719:        tmux renamew -t1: newname               (session 1's current window)
                   1720:        tmux renamew -t/dev/ttypi newname       (client /dev/ttypi's current
                   1721:                                                 session and window)
                   1722:        tmux renamew -t/dev/ttypi: newname      (client /dev/ttypi's current
                   1723:                                                 session and window)
                   1724:        tmux renamew -t/dev/ttypi:0 newname     (client /dev/ttypi's current
                   1725:                                                 session, window 0)
                   1726: 
                   1727:   This does have some downsides, for example, having to use -t on selectw,
                   1728: 
                   1729:        tmux selectw -t7
                   1730: 
                   1731:   is annoying. But then using non-flagged arguments would mean renaming the
                   1732:   current window would need to be something like:
                   1733: 
                   1734:        tmux renamew : newname
                   1735: 
                   1736:   It might be better not to try and be so consistent; comments to the usual
                   1737:   address ;-).
                   1738: * Infrastructure for printing arguments in list-keys output. Easy ones only for
                   1739:   now.
                   1740: 
                   1741: 04 June 2008
                   1742: 
                   1743: * Add some vi(1) key bindings in copy mode, and support binding ^[, ^\, ^]
                   1744:   ^^ and ^_. Both from/prompted by Will Maier.
                   1745: * setw monitor-activity and set status without arguments now toggle the current
                   1746:   value; suggested by merdely.
                   1747: * New command set-window-option (alias setw) to set the single current window
                   1748:   option: monitor-activity to determine whether window activity is shown in
                   1749:   the status bar for that window (default off).
                   1750: * Change so active/bell windows are inverted in status line.
                   1751: * Activity monitoring - window with activity are marked in status line. No
                   1752:   way to disable this/filter windows yet.
                   1753: * Brought select-window command into line with everything else; it now uses
                   1754:   -i for the window index.
                   1755: * Strings to display on the left and right of the status bar may now be set
                   1756:   with the status-left and status-right options. These are passed through
                   1757:   strftime(3) before being displayed. The status bar is automatically updated
                   1758:   at an interval set by the status-interval option. The default is to display
                   1759:   nothing on the left and the date and time on the left; the default update
                   1760:   interval is 15 seconds.
                   1761: 
                   1762: 03 June 2008
                   1763: 
                   1764: * Per session options. Setting options without specifying a session sets the
                   1765:   global options as normal (global options are inherited by all sessions);
                   1766:   passing -c or -s will set the option only for that session.
                   1767: * Because a client has a session attached, any command needing a session can
                   1768:   take a client and use its session. So, anything that used to accept -s now
                   1769:   accepts -c as well.
                   1770: * -s to specify session name now supports fnmatch(3) wildcards; if multiple
                   1771:   sessions are found, or if no -s is specified, the most newly created is used.
                   1772: * If no command is specified, assume new-session. As a byproduct, clean up
                   1773:   command default values into separate init functions.
                   1774: * kill-server command.
                   1775: 
                   1776: 02 June 2008
                   1777: 
                   1778: * New command, start-server (alias "start"), to start the tmux server and do
                   1779:   nothing else. This is good if you have a configuration file which creates
                   1780:   windows or sessions (like me): in that case, starting the server the first
                   1781:   time tmux new is run is bad since it creates a new session and window (as
                   1782:   it is supposed to - starting the server is a side-effect).
                   1783: 
                   1784:   Instead, I have a little script which does the equivalent of:
                   1785: 
                   1786:        tmux has -s0 2>/dev/null || tmux start
                   1787:        tmux attach -d -s0
                   1788: 
                   1789:   And I use it to start the server if necessary and attach to my primary
                   1790:   session.
                   1791: * Basic configuration file in ~/.tmux.conf or specified with -f. This is file
                   1792:   contains a set of tmux commands that are run the first time the server is
                   1793:   started. The configuration commands are executed before any others, so
                   1794:   if you have a configuration file that contains:
                   1795: 
                   1796:        new -d
                   1797:        neww -s0
                   1798: 
                   1799:   And you do the following without an existing server running:
                   1800: 
                   1801:        tmux new
                   1802: 
                   1803:   You will end up with two sessions, session 0 with two windows (created by
                   1804:   the configuration file) and your client attached to session 1 with one
                   1805:   window (created by the command-line command). I'm not completely happy with
                   1806:   this, it seems a little non-obvious, but I haven't yet decided what to do
                   1807:   about it.
                   1808: 
                   1809:   There is no environment variable handling or other special stuff yet.
                   1810: 
                   1811:   In the future, it might be nice to be able to have per-session configuration
                   1812:   settings, probably by having conditionals in the file (so you could, for
                   1813:   example, have commands to define a particular window layout that would only
                   1814:   be invoked if you called tmux new -smysession and mysession did not already
                   1815:   exist).
                   1816: * BIG CHANGE: -s and -c to specify session name and client name are now passed
                   1817:   after the command rather than before it. So, for example:
                   1818: 
                   1819:        tmux -s0 neww
                   1820: 
                   1821:   Becomes:
                   1822: 
                   1823:        tmux neww -s0
                   1824: 
                   1825:   This is to allow them to be used in the (forthcoming) configuration file
                   1826:   THIS WILL BREAK ANY CURRENT SCRIPTS OR ALIASES USING -s OR -c.
                   1827: 
                   1828: 01 June 2008
                   1829: 
                   1830: * Bug fix: don't die if -k passed to link-window and the destination doesn't
                   1831:   exist.
                   1832: * New command, send-keys, will send a set of keys to a window.
                   1833: 
                   1834: 31 May 2008
                   1835: 
                   1836: * Fix so tmux doesn't hang if the initial window fails for some reason. This
                   1837:   was highlighted by problems on Darwin, thanks to Elias Pipping for the report
                   1838:   and access to a test account. (tmux still won't work on Darwin since its
                   1839:   poll(2) is broken.)
                   1840: 
                   1841: 02 January 2008
                   1842: 
                   1843: * Don't attempt to reset the tty on exit if it has been closed externally.
                   1844: 
                   1845: 06 December 2007
                   1846: 
                   1847: * Restore checks for required termcap entries and add a few more obvious
                   1848:   emulations.
                   1849: * Another major reorganisation, this time of screen handling. A new set of
                   1850:   functions, screen_write_*, are now used to write to a screen and a tty
                   1851:   simultaneously. These are used by the input parser to update the base
                   1852:   window screen and also by the different modes which now interpose their own
                   1853:   screen.
                   1854: 
                   1855: 30 November 2007
                   1856: 
                   1857: * Support \ek...\e\ to set window name.
                   1858: 
                   1859: 27 November 2007
                   1860: 
                   1861: * Enable/disable mouse when asked, if terminal claims to support it. Mouse
                   1862:   sequences are just passed through unaltered for the moment.
                   1863: * Big internal reorganisation. Rather than leaving control of the tty solely in
                   1864:   the client and piping all data through a socket to it, change so that the
                   1865:   server opens the tty again and reads and writes to it directly. This avoids
                   1866:   a lot of buffering and copying. Also reorganise the redrawing stuff so that
                   1867:   everything goes through screen_draw_* - this makes the code simpler, but
                   1868:   still needs broken up more, and all the ways of writing to screens should be
                   1869:   more consistent.
                   1870: 
                   1871: 26 November 2007
                   1872: 
                   1873: * Rather than shifting up one line at a time once the history is full,
                   1874:   shift by 10% of the history each time. This is faster.
                   1875: * Add ^A and ^E to copy mode to move to start-of-line/end-of-line.
                   1876: 
                   1877: 24 November 2007
                   1878: 
                   1879: * Support for alt charset mode (VT100 graphics characters).
                   1880: 
                   1881: 23 November 2007
                   1882: 
                   1883: * Mostly complete copy & paste. Copy mode entered with C-b [ (copy-mode
                   1884:   command). In copy mode, arrow keys/page up/page down/hjkl/C-u/C-f navigate,
                   1885:   space or C-space starts selection, and enter or C-w copies and (important!)
                   1886:   exits copy mode. C-b ] (paste-buffer) pastes into current window. No
                   1887:   extra utility keys (bol/eol/clear selection/etc), only one single buffer,
                   1888:   and no buffer manipulation commands (clear/view/etc) yet. The code is also
                   1889:   fugly :-(.
                   1890: * history-limit option to set maximum history. Does not apply retroactively to
                   1891:   existing windows! Lines take up a variable amount of space, but a reasonable
                   1892:   guess for an 80-column terminal is 250 KB per 1000 lines (of history used,
                   1893:   an empty history takes no space).
                   1894: 
                   1895: 21 November 2007
                   1896: 
                   1897: * Create every line as zero length and only expand it as data is written,
                   1898:   rather than creating at full size immediately.
                   1899: * Make command output (eg list-keys) go to a scrollable window similar to
                   1900:   scroll mode.
                   1901: * Redo screen redrawing so it is a) readable b) split into utility functions
                   1902:   that can be used outside screen.c. Use these to make scroll mode only
                   1903:   redraw what it has to which gets rid of irritating flickering status box and
                   1904:   makes it much faster.
                   1905: * Full line width memory and horizontal scrolling in history.
                   1906: * Initial support for scroll history. = to enter scrolling mode, and then
                   1907:   vi keys or up/down/pgup/pgdown to navigate. Q to exit. No horizontal history
                   1908:   yet (need per-line sizes) and a few kinks to be worked out (resizing while in
                   1909:   history mode will probably cause trouble).
                   1910: 
                   1911: 20 November 2007
                   1912: 
                   1913: * Fix format string error with "must specify a client" message. Also
                   1914:   sprinkle some printflike tags.
                   1915: * tmux 0.1 released.
                   1916: 
                   1917: 17 November 2007
                   1918: 
                   1919: * (nicm) Add -k option to link-window to kill target window if it exists.
                   1920: 
                   1921: 16 November 2007
                   1922: 
                   1923: * (nicm) Split in-client display into two columns. This is a hack but not a lot
                   1924:   more so than that bit is already and it helps with lots of keys.
                   1925: * (nicm) switch-client command to switch client between different sessions. This
                   1926:   is pretty cool:
                   1927: 
                   1928:        $ tmux bind q switch 0
                   1929:        $ tmux bind w switch 1
                   1930: 
                   1931:   Then you can switch between sessions 0 and 1 with a key :-).
                   1932: * (nicm) Accept "-c client-tty" on command line to allow client manipulation
                   1933:   commands, and change detach-/refresh-session to detach-/refresh-client (this
                   1934:   loses the -a behaviour, but at some point -session versions may return, and
                   1935:   -c will allow fnmatch(3)).
                   1936: * (nicm) List available commands on ambiguous command.
                   1937:

                   1941:   background and white foreground to default. This is useful on transparent

                   1943: * (nicm) Fill in the rest of the man page.

                   1963: 
                   1964: * (nicm) swap-window command. Same as link-window but swaps windows.
                   1965: 
                   1966: 26 October 2007
                   1967: 
                   1968: * (nicm) Saving scroll region on \e7 causes problems with ncmpc so I guess
                   1969:   it is not required.
                   1970: * (nicm) unlink-window command.
                   1971: * (nicm) link-window command to link an existing window into another session
                   1972:   (or another index in the same session). Syntax:
                   1973: 
                   1974:        tmux -s dstname link-window [-i dstidx] srcname srcidx
                   1975: 
                   1976: * (nicm) Redo window data structures. The global array remains, but each per-
                   1977:   session list is now a RB tree of winlink structures. This disassociates the
                   1978:   window index from the array size (allowing arbitrary indexes) which still
                   1979:   allowing windows to have multiple indexes.

                   1989:   Currently don't save mode (probably should). Also change some cases where
                   1990:   out-of-bound values are ignored to limit them to within range (there are
                   1991:   others than need to be checked too).
                   1992:

                   2000: 20 October 2007
                   2001: 
                   2002: * (nicm) Add default-command option and change default to be $SHELL rather than
                   2003:   $SHELL -l. Also try to read shell from passwd db if $SHELL isn't present.
                   2004: 
                   2005: 19 October 2007

                   2007: * (nicm) -n on new-session is now -s, and -n is now the initial window name.
                   2008:   This was documented but not implemented :-/.
                   2009: * (nicm) kill-window command, bound to & by default (because it should be hard
                   2010:   to hit accidently).
                   2011: * (nicm) bell-style option with three choices: "none" completely ignore bell;
                   2012:   "any" pass through a bell in any window to current; "current" ignore bells
                   2013:   except in current window. This applies only to the bell terminal signal,
                   2014:   the status bar always reflects any bells.
                   2015: * (nicm) Refresh session command.
                   2016:

                   2022:   from 0 to 8 or a string ("red", "blue", etc). status may be 1/0, on/off,
                   2023:   yes/no.
                   2024: * (nicm) Make status line mark window in yellow on bell.
                   2025: 
                   2026: 04 October 2007
                   2027: 
                   2028: * (nicm) -d option to attach to detach all other clients on the same session.
                   2029: * (nicm) Partial resizing support. Still buggy. A C-b S and back sometimes fixes
                   2030:   it when it goes wonky.
                   2031: * (mxey) Added my tmux start script as an example (examples/start-tmux.sh).
                   2032: * (mxey) New sessions can now be given a command for their first window.
                   2033: * (mxey) Fixed usage statement for new-window.
                   2034: * (nicm) attach-session (can't believe I forgot it until now!) and list-windows
                   2035:   commands.
                   2036: * (nicm) rename-window and select-window commands.
                   2037: * (nicm) set-option command (alias set): "tmux set-option prefix ^A".
                   2038: * (nicm) Key binding and unbinding is back.
                   2039:

                   2041: 
                   2042: * (nicm) {new,next,last,previous}-window.
                   2043: * (nicm) Rewrite command handling so commands are much more generic and the
                   2044:   same commands are used for command line and keys (although most will probably
                   2045:   need to check how they are called). Currently incomplete (only new/detach/ls
                   2046:   implemented). Change: -s is now passed before command again!
                   2047: * (nicm) String number arguments. So you can do: tmux bind ^Q create "blah".
                   2048: * (nicm) Key binding. tmux bind key command [argument] and tmux unbind key.
                   2049:   Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A.
                   2050:   Possible commands are in cmd.c (look at cmd_bind_table).
                   2051: * (nicm) Move command parsing into the client. Also rename some messages and
                   2052:   tidy up a few bits. Lots more tidying up needed :-/.
                   2053: 
                   2054: 02 October 2007
                   2055: 
                   2056: * (nicm) Redraw client status lines on rename.
                   2057: * (nicm) Error on ambiguous command.
                   2058: 
                   2059: 01 October 2007
                   2060: 
                   2061: * (nicm) Restore window title handling.
                   2062: * (nicm) Simple uncustomisable status line with window list.
                   2063: 
                   2064: 30 September 2007
                   2065: 
                   2066: * (nicm) Window info command for debugging, C-b I.
                   2067: 
                   2068: 29 September 2007
                   2069: 
                   2070: * (nicm) Deleting/inserting lines should follow scrolling region. Fix.
                   2071: * (nicm) Allow creation of detached sessions: "tmux new-session -d".
                   2072: * (nicm) Permit error messages to be passed back for transient clients like
                   2073:   rename. Also make rename -i work.
                   2074: * (nicm) Pass through bell in any window to current.
                   2075:

                   2077: 
                   2078: * (nicm) Major rewrite of input parser:
                   2079:        - Lose the old weirdness in favour of a state machine.
                   2080:        - Merge in parsing from screen.c.
                   2081:        - Split key parsing off into a separate file.
                   2082:   This is step one towards hopefully allowing a status line. It requires
                   2083:   that we output data as if the terminal had one line less than it really does -
                   2084:   a serious problem when it comes to things like scrolling. This change
                   2085:   consolidates all the range checking and limiting together which should make
                   2086:   it easier.
                   2087: * (mxey) Added window renaming, like "tmux rename [-s session] [-i index] name"
                   2088: 
                   2089: 27 September 2007
                   2090: 
                   2091: * Split "tmux list" into "tmux list-sessions" (ls) and "list-windows" (lsw).
                   2092: * New command session selection:
                   2093:        - if name is specified, look for it and use it if it exists, otherwise
                   2094:          error
                   2095:        - if no name specified, try the current session from $TMUX
                   2096:        - if $TMUX doesn't exist, and there is only one session, use it,
                   2097:          otherwise error
                   2098: 
                   2099: 26 September 2007
                   2100: 
                   2101: * Add command aliases, so "ls" is an alias for "list".
                   2102: * Rename some commands and alter syntax to take options after a la CVS. Also
                   2103:   change some flags. So:
                   2104: 
                   2105:        tmux -s/socket -nabc new
                   2106: 
                   2107:   Becomes:
                   2108: 
                   2109:        tmux -S/socket new -sabc
                   2110:

                   2114: 
                   2115: * Window list command (C-b W). Started by Maximilian Gass, finished by me.
                   2116: 
                   2117: 20 September 2007
                   2118: 
                   2119: * Specify meta via environment variable (META).
                   2120: * Record last window and ^L key to switch to it. Largely from Maximilian Gass.
                   2121: * Reset ignored signals in child after forkpty, makes ^C work.
                   2122: * Wrap on next/previous. From Maximilian Gass.
                   2123: 
                   2124: 19 September 2007
                   2125: 
                   2126: * Don't renumber windows on close.
                   2127: 
                   2128: 28 August 2007
                   2129: 
                   2130: * Scrolling region (\e[r) support.

                   2132: 27 August 2007
                   2133: 
                   2134: * Change screen.c to work more logically and hopefully fix heap corruption.
                   2135: 
                   2136: 09 July 2007
                   2137: 
                   2138: * Initial import to CVS. Basic functions are working, albeit with a couple of
                   2139:   showstopper memory bugs and many missing features. Detaching, reattaching,
                   2140:   creating new sessions, listing sessions work acceptably for using with shells.
                   2141:   Simple curses programs (top, systat, tetris) and more complicated ones (mutt,
                   2142:   emacs) that don't require scrolling regions (ESC[r) mostly work fine
                   2143:   (including mutt, emacs). No status bar yet and no key remapping or other
                   2144:   customisation.
