|  |  | 
|  | Incompatible Changes | 
|  | ==================== | 
|  |  | 
|  | * layout redo/undo has been removed. | 
|  |  | 
|  | Normal Changes | 
|  | ============== | 
|  |  | 
|  | * Add halfpage up/down bindings to copy mode. | 
|  | * Session choosing fixed to work with unattached sessions. | 
|  | * New window options window-status-last-{attr,bg,fg} to denote the last | 
|  | window which was active. | 
|  | * Scrolling in copy-mode now scrolls the region without moving the mouse | 
|  | cursor. | 
|  | * run-shell learnt '-t' to specify the pane to use when displaying output. | 
|  | * Support for middle-click pasting. | 
|  | * choose-tree learns '-u' to start uncollapsed. | 
|  | * select-window learnt '-T' to toggle to the last window if it's already | 
|  | current. | 
|  | * New session option 'assume-paste-time' for pasting text versus key-binding | 
|  | actions. | 
|  | * choose-* commands now work outside of an attached client. | 
|  | * Aliases are now shown for list-commands command. | 
|  | * Status learns about formats. | 
|  | * Free-form options can be set with set-option if prepended with an '@' | 
|  | sign. | 
|  | * capture-pane learnt '-p' to send to stdout, and '-e' for capturing escape | 
|  | sequences, and '-a' to capture the alternate screen, and '-P' to dump | 
|  | pending output. | 
|  | * Many new formats added (client_session, client_last_session, etc.) | 
|  | * Control mode, which is a way for a client to send tmux commands. | 
|  | Currently more useful to users of iterm2. | 
|  | * resize-pane learnt '-x' and '-y' for absolute pane sizing. | 
|  | * Config file loading now reports errors from all files which are loaded via | 
|  | the 'source-file' command. |

|  | * capture-pane and show-options learns '-q' to silence errors. | 
|  | * New command 'wait-for' which blocks a client until woken up again. | 
|  | * Resizing panes will now reflow the text inside them. | 
|  | * Lots and lots of bug fixes, fixing memory-leaks, etc. | 
|  | * Various manpage improvements. | 
|  |  | 
|  | CHANGES FROM 1.6 to 1.7, 13 October 2012 | 
|  |  | 
|  | * tmux configuration files now support line-continuation with a "\" at the | 
|  | end of a line. | 
|  | * New option status-position to move the status line to the top or bottom of | 
|  | the screen. | 
|  | * Enforce history-limit option when clearing the screen. | 
|  | * Give each window a unique id, like panes but prefixed with @. | 
|  | * Add pane id to each pane in layout description (while still accepting | 
|  | the old form). | 
|  | * Provide defined ways to set the various default-path possibilities: ~ | 
|  | for home directory, . for server start directory, - for session start | 
|  | directory and empty for the pane's working directory (the default). All | 
|  | can also be used as part of a relative path (eg -/foo). Also provide -c | 
|  | flags to neww and splitw to override default-path setting. | 
|  | * Add -l flag to send-keys to send input literally (without translating | 
|  | key names). | 
|  | * Allow a single option to be specified to show-options to show just that | 
|  | option. | 
|  | * New command "move-pane" (like join-pane but allows the same window). | 
|  | * join-pane and move-pane commands learn "-b" option to place the pane to | 
|  | the left or above. | 
|  | * Support for bracketed-paste mode. | 
|  | * Allow send-keys command to accept hex values. | 
|  | * Add locking around "start-server" to avoid race-conditions. | 
|  | * break-pane learns -P/-F arguments for display formatting. | 
|  | * set-option learns "-q" to make it quiet, and not print out anything. | 
|  | * copy mode learns "wrap-search" option. | 
|  | * Add a simple form of output rate limiting by counting the number of | 
|  | certain C0 sequences (linefeeds, backspaces, carriage returns) and if it | 
|  | exceeds a threshold (current default 250/millisecond), start to redraw | 
|  | the pane every 100 milliseconds instead of making each change as it | 
|  | comes. Two configuration options - c0-change-trigger and | 
|  | c0-change-interval. | 
|  | * find-window learns new flags:  "-C", "-N", "-T" to match against either or | 
|  | all of a window's content, name, or title.  Defaults to all three options | 
|  | if none specified. | 
|  | * find-window automatically selects the appropriate pane for the found | 
|  | matches. | 
|  | * show-environment can now accept one option to show that environment value. | 
|  | * Exit mouse mode when end-of-screen reached when scrolling with the mouse | 
|  | wheel. | 
|  | * select-layout learns -u and -U for layout history stacks. | 
|  | * kill-window, detach-client, kill-session all  learn "-a" option for | 
|  | killing all but the current thing specified. | 
|  | * move-window learns "-r" option to renumber window sequentially in a | 
|  | session. | 
|  | * New session option "renumber-windows" to automatically renumber windows in | 
|  | a session when a window is closed.  (see "move-window -r"). | 
|  | * Only enter copy-mode on scroll up. | 
|  | * choose-* and list-* commands all use "-F" for format specifiers. | 
|  | * When spawning external commands, the value from the "default-shell" option | 
|  | is now used, rather than assuming /bin/sh. | 
|  | * New choose-tree command to render window/sessions as a tree for selection. | 
|  | * display-message learns new format options. | 
|  | * For linked-windows across sessions, all flags for that window are now | 
|  | cleared across sessions. | 
|  | * Lots and lots of bug fixes, fixing memory-leaks, etc. | 
|  | * Various manpage improvements. | 
|  |  | 
|  | CHANGES FROM 1.5 TO 1.6, 23 January 2012 | 
|  |  | 
|  | * Extend the mode-mouse option to add a third choice which means the mouse | 
|  | does not enter copy mode. | 
|  | * Add a -r flag to switch-client to toggle the client read-only flag. | 
|  | * Add pane-base-index option. | 
|  | * Support \ for line continuation in the configuration file. | 
|  | * Framework for more powerful formatting of command output and use it for | 
|  | list-{panes,windows,sessions}. This allows more descriptive replacements | 
|  | (such as #{session_name}) and conditionals. | 
|  | * Mark dead panes with some text saying they are dead. | 
|  | * Reject $SHELL if it is not a full path. | 
|  | * Add -S option to refresh-client to redraw status line. | 
|  | * Add an else clause for if-shell. | 
|  | * Try to resolve relative paths for loadb and saveb (first, using client | 
|  | working directory, if any, then default-path or session working directory). | 
|  | * Support for \e[3J to clear the history and send the corresponding | 
|  | terminfo code (E3) before locking. | 
|  | * When in copy mode, make repeat count indicate buffer to replace, if used. | 
|  | * Add screen*:XT to terminal-overrides for tmux-in-tmux. | 
|  | * Status-line message attributes added. | 
|  | * Move word-separators to be a session rather than window option. | 
|  | * Change the way the working directory for new processes is discovered. If | 
|  | default-path isn't empty, it is used. Otherwise, if a new window is created | 
|  | from the command-line, the working directory of the client is used. If not, | 
|  | platform specific code is used to retrieve the current working directory | 
|  | of the process in the active pane. If that fails, the directory where the | 
|  | session was created is used, instead. | 
|  | * Do not change the current pane if both mouse-select-{pane,window} are | 
|  | enabled. | 
|  | * Add \033[s and \033[u to save and restore cursor position. | 
|  | * Allow $HOME to be used as default-path. | 
|  | * Add CNL and CPL escape sequences. | 
|  | * Calculate last position correctly for UTF-8 wide characters. | 
|  | * Add an option allow-rename to disable the window rename escape sequence. | 
|  | * Attributes for each type of status-line alert (ie bell, content and | 
|  | activity) added. Therefore, remove the superfluous options | 
|  | window-status-alert-{attr,bg,fg}. | 
|  | * Add a -R flag to send-keys to reset the terminal. | 
|  | * Add strings to allow the aixterm bright colours to be used when | 
|  | configuring colours. | 
|  | * Drop the ability to have a list of keys in the prefix in favour of two | 
|  | separate options, prefix and prefix2. | 
|  | * Flag -2 added to send-prefix to send the secondary prefix key. | 
|  | * Show pane size in top right of display panes mode. | 
|  | * Some memory leaks plugged. | 
|  | * More command-prompt editing improvements. | 
|  | * Various manpage improvements. | 
|  | * More Vi mode improvements. | 
|  |  | 
|  | CHANGES FROM 1.4 TO 1.5, 09 July 2011 | 
|  |  | 
|  | * Support xterm mouse modes 1002 and 1003. | 
|  | * Change from a per-session stack of buffers to one global stack. This renders | 
|  | copy-buffer useless and makes buffer-limit now a server option. | 
|  | * Fix most-recently-used choice by avoiding reset the activity timer for | 
|  | unattached sessions every second. | 
|  | * Add a -P option to new-window and split-window to print the new window or | 
|  | pane index in target form (useful to pass it into other commands). | 
|  | * Handle a # at the end of a replacement string (such as status-left) | 
|  | correctly. | 
|  | * Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262. | 
|  | If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all | 
|  | UTF-8 terminals. The option defaults to on if LANG etc are set in the same | 
|  | manner as the utf8 option. | 
|  | * Support for HP-UX. | 
|  | * Accept colours of the hex form #ffffff and translate to the nearest from the | 
|  | xterm(1) 256-colour set. | 
|  | * Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors | 
|  | before closing them (fixes things like "tmux ls && cat"). | 
|  | * Use TMPDIR if set. | 
|  | * Fix next and previous session functions to actually work. | 
|  | * Support -x and -y for new-session to specify the initial size of the window | 
|  | if created detached with -d. | 
|  | * Make bind-key accept characters with the top-bit-set and print them as octal. | 
|  | * Set $TMUX without the session when background jobs are run. | 
|  | * Simplify the way jobs work and drop the persist type, so all jobs are | 
|  | fire-and-forget. | 
|  | * Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the | 
|  | terminal disappears while locked. | 
|  | * Add a -P option to detach to HUP the client's parent process (usually causing | 
|  | it to exit as well). | 
|  | * Support passing through escape sequences to the underlying terminal by using | 
|  | DCS with a "tmux;" prefix. | 
|  | * Prevent tiled producing a corrupt layout when only one column is needed. | 
|  | * Give each pane created in a tmux server a unique id (starting from 0), put it | 
|  | in the TMUX_PANE environment variable and accept it as a target. | 
|  | * Allow a start and end line to be specified for capture-pane which may be | 
|  | negative to capture part of the history. | 
|  | * Add -a and -s options to lsp to list all panes in the server or session | 
|  | respectively. Likewise add -s to lsw. | 
|  | * Change -t on display-message to be target-pane for the #[A-Z] replacements | 
|  | and add -c as target-client. | 
|  | * The attach-session command now prefers the most recently used unattached | 
|  | session. | 
|  | * Add -s option to detach-client to detach all clients attached to a session. | 
|  | * Add -t to list-clients. | 
|  | * Change window with mouse wheel over status line if mouse-select-window is on. | 
|  | * When mode-mouse is on, automatically enter copy mode when the mouse is | 
|  | dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel | 
|  | is scrolled off the bottom. | 
|  | * Provide #h character pair for short hostname (no domain). | 
|  | * Don't use strnvis(3) for the title as it breaks UTF-8. | 
|  | * Use the tsl and fsl terminfo(5) capabilities to update terminal title and | 
|  | automatically fill them in on terminals with the XT capability (which means | 
|  | their title setting is xterm-compatible). | 
|  | * Add a new option, mouse-resize-pane. When on, panes may be resized by | 
|  | dragging their borders. | 
|  | * Fix crash by resetting last pane on {break,swap}-pane across windows. | 
|  | * Add three new copy-mode commands - select-line, copy-line, copy-end-of-line. | 
|  | * Support setting the xterm clipboard when copying from copy mode using the | 
|  | xterm escape sequence for the purpose (if xterm is configured to allow it). | 
|  | * Support xterm(1) cursor colour change sequences through terminfo(5) Cc | 
|  | (set) and Cr (reset) extensions. | 
|  | * Support DECSCUSR sequence to set the cursor style with two new terminfo(5) | 
|  | extensions, Cs and Csr. | 
|  | * Make the command-prompt custom prompts recognize the status-left option | 
|  | character pairs. | 
|  | * Add a respawn-pane command. | 
|  | * Add a couple of extra xterm-style keys that gnome terminal provides. | 
|  | * Allow the initial context on prompts to be set with the new -I option to | 
|  | command-prompt. Include the current window and session name in the prompt | 
|  | when renaming and add a new key binding ($) for rename session. | 
|  | * Option bell-on-alert added to trigger the terminal bell when there is an | 
|  | alert. | 
|  | * Change the list-keys format so that it shows the keys using actual tmux | 
|  | commands which should be able to be directly copied into the config file. | 
|  | * Show full targets for lsp/lsw -a. | 
|  | * Make confirm-before prompt customizable with -p option like command-prompt | 
|  | and add the character pairs #W and #P to the default kill-{pane,window} | 
|  | prompts. | 
|  | * Avoid sending data to suspended/locked clients. | 
|  | * Small memory leaks in error paths plugged. | 
|  | * Vi mode improvements. | 
|  |  | 
|  | CHANGES FROM 1.3 TO 1.4, 27 December 2010 | 
|  |  | 
|  | * Window bell reporting fixed. | 
|  | * Show which pane is active in the list-panes output. | 
|  | * Backoff reworked. | 
|  | * Prevent the server from dying when switching into copy mode when already | 
|  | in a different mode. | 
|  | * Reset running jobs when the status line is enabled or disabled. | 
|  | * Simplify xterm modifier detection. | 
|  | * Avoid crashing in copy mode if the screen size is too small for the | 
|  | indicator. | 
|  | * Flags -n and -p added to switch-client. | 
|  | * Use UTF-8 line drawing characters on UTF-8 terminals, thus fixing some | 
|  | terminals (eg putty) which disable the vt100 ACS mode switching sequences | 
|  | in UTF-8 mode. On terminals without ACS, use ASCII equivalents. | 
|  | * New server option exit-unattached added. | 
|  | * New session option destroy-unattached added. | 
|  | * Fall back on normal session choice method if $TMUX exists but is invalid | 
|  | rather than rejecting. | 
|  | * Mark repeating keys with "(repeat)" in the key list. | 
|  | * When removing a pane, don't change the active pane unless the active pane | 
|  | is actually the one being removed. | 
|  | * New command last-pane added. | 
|  | * AIX fixes. | 
|  | * Flag -a added to unbind-key. | 
|  | * Add XAUTHORITY to update-environment. | 
|  | * More info regarding window and pane flags is now shown in list-*. | 
|  | * If VISUAL or EDITOR contains "vi" configure mode-keys and status-key to vi. | 
|  | * New window option monitor-silence and session option visual-silence added. | 
|  | * In the built-in layouts distribute the panes more evenly. | 
|  | * Set the default value of main-pane-width to 80 instead of 81. | 
|  | * Command-line flag -V added. | 
|  | * Instead of keeping a per-client prompt history make it global. | 
|  | * Fix rectangle copy to behave like emacs (the cursor is not part of the | 
|  | selection on the right edge but on the left it is). | 
|  | * Flag -l added to switch-client. | 
|  | * Retrieve environment variables from the global environment rather than | 
|  | getenv(3), thus allowing them to be updated during the configuration file. | 
|  | * New window options other-pane-{height,width} added. | 
|  | * More minor bugs fixed and manpage improvements. | 
|  |  | 
|  | CHANGES FROM 1.2 TO 1.3, 18 July 2010 | 
|  |  | 
|  | * New input parser. | 
|  | * Flags to move through panes -UDLR added to select-pane. | 
|  | * Commands up-pane, and down-pane removed, since equivalent behaviour is now | 
|  | available through the target flag (-t:+ and -t:-). | 
|  | * Jump-forward/backward in copy move (based on vi's F, and f commands). | 
|  | * Make paste-buffer accept a pane as a target. | 
|  | * Flag -a added to new-window to insert a window after an existing one, moving | 
|  | windows up if necessary. | 
|  | * Merge more mode into copy mode. | 
|  | * Run job commands explicitly in the global environment (which can be modified | 
|  | with setenv -g), rather than with the environment tmux started with. | 
|  | * Use the machine's hostname as the default title, instead of an empty string. | 
|  | * Prevent double free if the window option remain-on-exit is set. | 
|  | * Key string conversions rewritten. | 
|  | * Mark zombie windows as dead in the choose-window list. | 
|  | * Tiled layout added. | 
|  | * Signal handling reworked. | 
|  | * Reset SIGCHLD after fork to fix problems with some shells. | 
|  | * Select-prompt command removed. Therefore, bound ' to command-prompt -p index | 
|  | "select-window -t:%%" by default. | 
|  | * Catch SIGHUP and terminate if running as a client, thus avoiding clients from | 
|  | being left hanging around when, for instance, a SSH session is disconnected. | 
|  | * Solaris 9 fixes (such as adding compat {get,set}env(3) code). | 
|  | * Accept none instead of default for attributes. | 
|  | * Window options window-status-alert-{alert,bg,fg} added. | 
|  | * Flag -s added to the paste-buffer command to specify a custom separator. | 
|  | * Allow dragging to make a selection in copy mode if the mode-mouse option is | 
|  | set. | 
|  | * Support the mouse scroll wheel. | 
|  | * Make pipe-pane accept special character sequences (eg #I). | 
|  | * Fix problems with window sizing when starting tmux from .xinitrc. | 
|  | * Give tmux sockets (but not the containing folder) group permissions. | 
|  | * Extend the target flags (ie -t) to accept an offset (for example -t:+2), and | 
|  | make it wrap windows, and panes. | 
|  | * New command choose-buffer added. | 
|  | * New server option detach-on-destroy to set what happens to a client when the | 
|  | session it is attached to is destroyed. If on (default), the client is | 
|  | detached. Otherwise, the client is switched to the most recently active of | 
|  | the remaining sessions. | 
|  | * The commands load-buffer, and save-buffer now accept a dash (-) as the file | 
|  | to read from stdin, or write to stdout. | 
|  | * Custom layouts added. | 
|  | * Additional code reduction, bug fixes, and manpage enhancements. | 
|  |  | 
|  | CHANGES FROM 1.1 TO 1.2, 10 March 2010 | 
|  |  | 
|  | * Switch to libevent. | 
|  | * Emulate the ri (reverse index) capability, ergo allowing tmux to at least | 
|  | start on Sun consoles (TERM=sun, or sun-color). | 
|  | * Assign each entry a number, or lowercase letter in choose mode, and accept | 
|  | that as a shortcut key. | 
|  | * Permit top-bit-set characters to be entered in the status line. | 
|  | * Mark no-prefix keys with (no prefix), rather than [] in list-keys. | 
|  | * New command show-messages (alias showmsgs), and new session option | 
|  | message-limit, to show a per-client log of status lines messages up to the | 
|  | number defined by message-limit. | 
|  | * Do not interpret #() for display-message to avoid leaking commands. | 
|  | * New window options window-status-format, and window-status-current-format to | 
|  | control the format of each window in the status line. | 
|  | * Add a -p flag to display-message to print the output, instead of displaying | 
|  | it in the status line. | 
|  | * Emulate il1, dl1, ich1 to run with vt100 feature set. | 
|  | * New command capture-pane (alias capturep) to copy the entire pane contents | 
|  | to a paste buffer. | 
|  | * Avoid duplicating code by adding a -w flag to set-option, and show-options to | 
|  | set, and show window options. The commands set-window-option, and | 
|  | show-window-options are now aliases. | 
|  | * Panes can now be referred to as top, bottom, top-left, etc. | 
|  | * Add server-wide options, which can be set with set-option -s, and shown with | 
|  | show-options -s. | 
|  | * New server option quiet (like -q from the command line). | 
|  | * New server option escape-time to set the timeout used to detect if escapes | 
|  | are alone, part of a function key, or meta sequence. | 
|  | * New session options pane-active-border-bg, pane-active-border-fg, | 
|  | pane-border-bg, and pane-border-fg to set pane colours. | 
|  | * Make split-window accept a pane target, instead of a window. | 
|  | * New command join-pane (alias joinp) to split, and move an existing pane into | 
|  | the space (the opposite of break-pane), thus simplifying calls to | 
|  | split-window, followed by move-window. | 
|  | * Permit S- prefix on keys for shift when the terminal/terminfo supports them. | 
|  | * Window targets (-t flag) can now refer to the last window (!), next (+), and | 
|  | previous (-) window by number. | 
|  | * Mode keys to jump to the bottom/top of history, end of the next word, scroll | 
|  | up/down, and reverse search in copy mode. | 
|  | * New session option display-panes-active-colour to display the active pane in | 
|  | a different colour with the display-panes command. | 
|  | * Read the socket path from $TMUX if it's present, and -L, and -S are not | 
|  | given. | 
|  | * Vi-style mode keys B, W, and E to navigate between words in copy mode. | 
|  | * Start in more mode when configuration file errors are detected. | 
|  | * Rectangle copy support added. | 
|  | * If attach-session was specified with the -r flag, make the client read-only. | 
|  | * Per-window alternate-screen option. | 
|  | * Make load-buffer work with FIFOs. | 
|  | * New window option word-separators to set the characters considered as word | 
|  | separators in copy mode. | 
|  | * Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9] | 
|  | in vi mode, or M-[1-9] in emacs mode. | 
|  | * utf8 improvements. | 
|  | * As usual, additional code reduction, bug fixes, and manpage enhancements. | 
|  |  | 
|  | CHANGES FROM 1.0 TO 1.1, 05 November 2009 | 
|  |  | 
|  | * New run-shell (alias run) command to run an external command without a | 
|  | window, capture it's stdout, and send it to output mode. | 
|  | * Ability to define multiple prefix keys. | 
|  | * Internal locking mechanism removed. Instead, detach each client and run the | 
|  | external command specified in the new session option lock-command (by default | 
|  | lock -np), thus allowing the system password to be used. | 
|  | * set-password command, and -U command line flag removed per the above change. | 
|  | * Add support for -c command line flag to execute a shell command. | 
|  | * New lock-client (alias lockc), and lock-session (alias locks) commands to | 
|  | lock a particular client, or all clients attached to a session. | 
|  | * Support C-n/C-p/C-v/M-v with emacs keys in choice mode. | 
|  | * Use : for goto line rather than g in vi mode. | 
|  | * Try to guess which client to use when no target client was specified. Finds | 
|  | the current session, and if only one client is present, use it. Otherwise, | 
|  | return the most recently used client. | 
|  | * Make C-Down/C-Up in copy mode scroll the screen down/up one line without | 
|  | moving the cursor. | 
|  | * Scroll mode superseded by copy mode. | 
|  | * New synchronize-panes window option to send all input to all other panes in | 
|  | the same window. | 
|  | * New lock-server session option to lock, when off (on by default), each | 
|  | session when it has been idle for the lock-after-time setting. When on, the | 
|  | entire server locks when all sessions have been idle for their individual | 
|  | lock-after-time setting. | 
|  | * Add support for grouped sessions which have independent name, options, | 
|  | current window, but where the linked windows are synchronized (ie creating, | 
|  | killing windows are mirrored between the sessions). A grouped session may be | 
|  | created by passing -t to new-session. | 
|  | * New mouse-select-pane session option to select the current pane with the | 
|  | mouse. | 
|  | * Queue, and run commands in the background for if-shell, status-left, | 
|  | status-right, and #() by starting each once every status-interval. Adds the | 
|  | capability to call some programs which would previously cause the server to | 
|  | hang (eg sleep/tmux). It also avoids running commands excessively (ie if used | 
|  | multiple times, it will be run only once). | 
|  | * When a window is zombified and automatic-rename is on, append [dead] to the | 
|  | name. | 
|  | * Split list-panes (alias lsp) off from list-windows. | 
|  | * New pipe-pane (alias pipep) to redirect a pane output to an external command. | 
|  | * Support for automatic-renames for Solaris. | 
|  | * Permit attributes to be turned off in #[] by prefixing with no (eg nobright). | 
|  | * Add H/M/L in vi mode, and M-R/M-r in emacs to move the cursor to the top, | 
|  | middle, and bottom of the screen. | 
|  | * -a option added to kill-pane to kill all except current pane. | 
|  | * The -d command line flag is now gone (can be replaced by terminal-overrides). | 
|  | Just use op/AX to detect default colours. | 
|  | * input/tty/utf8 improvements. | 
|  | * xterm-keys rewrite. | 
|  | * Additional code reduction, and bug fixes. | 
|  |  | 
|  | CHANGES FROM 0.9 TO 1.0, 20 Sept 2009 | 
|  |  | 
|  | * Option to alter the format of the window title set by tmux. | 
|  | * Backoff for a while after multiple incorrect password attempts. | 
|  | * Quick display of pane numbers (C-b q). | 
|  | * Better choose-window, choose-session commands and a new choose-client command. | 
|  | * Option to request multiple responses when using command-prompt. | 
|  | * Improved environment handling. | 
|  | * Combine wrapped lines when pasting. | 
|  | * Option to override terminal settings (terminal-overrides). | 
|  | * Use the full range of ACS characters for drawing pane separator lines. | 
|  | * Customisable mode keys. | 
|  | * Status line colour options, with embedded colours in status-left/right, and | 
|  | an option to centre the window list. | 
|  | * Much improved layouts, including both horizontal and vertical splitting. | 
|  | * Optional visual bell, activity and content indications. | 
|  | * Set the utf8 and status-utf8 options when the server is started with -u. | 
|  | * display-message command to show a message in the status line, by default some | 
|  | information about the current window. | 
|  | * Improved current process detection on NetBSD. | 
|  | * unlink-window -k is now the same as kill-window. | 
|  | * attach-session now works from inside tmux. | 
|  | * A system-wide configuration file, /etc/tmux.conf. | 
|  | * A number of new commands in copy mode, including searching. | 
|  | * Panes are now specified using the target (-t) notation. | 
|  | * -t now accepts fnmatch(3) patterns and looks for prefixes. | 
|  | * Translate \r into \n when pasting. | 
|  | * Support for binding commands to keys without the prefix key | 
|  | * Support for alternate screen (terminfo smcup/rmcup). | 
|  | * Maintain data that goes off screen after reducing the window size, so it can | 
|  | be restored when the size is increased again. | 
|  | * New if-shell command to test a shell command before running a tmux command. | 
|  | * tmux now works as the shell. | 
|  | * Man page reorganisation. | 
|  | * Many minor additions, much code tidying and several bug fixes. | 
|  |  | 
|  | CHANGES FROM 0.8 TO 0.9, 01 July 2009 | 
|  |  | 
|  | * Major changes to build infrastructure: cleanup of makefiles and addition | 
|  | of a configure script. | 
|  | * monitor-content window option to monitor a window for a specific fnmatch(3) | 
|  | pattern. The find-window command also now accepts fnmatch(3) patterns. | 
|  | * previous-layout and select-layout commands, and a main-horizontal layout. | 
|  | * Recreate the server socket on SIGUSR1. | 
|  | * clear-history command. | 
|  | * Use ACS line drawing characters for pane separator lines. | 
|  | * UTF-8 improvements, and code to detect UTF-8 support by looking at | 
|  | environment variables. | 
|  | * The resize-pane-up and resize-pane-down commands are now merged together | 
|  | into a new resize-pane command with -U and -D flags. | 
|  | * confirm-before command to request a yes/no answer before executing dangerous | 
|  | commands. | 
|  | * Status line bug fixes, support for UTF-8 (status-utf8 option), and a key to | 
|  | paste from the paste buffer. | 
|  | * Support for some additional escape sequences and terminal features, including | 
|  | better support for insert mode and tab stops. | 
|  | * Improved window resizing behaviour, modelled after xterm. | 
|  | * Some code reduction and a number of miscellaneous bug fixes. | 
|  |  | 
|  | ================================================================================ | 
|  |  | 
|  | On 01 June 2009, tmux was imported into the OpenBSD base system. From this date | 
|  | onward changes are logged as part of the normal CVS commit message to either | 
|  | OpenBSD or SourceForge CVS. This file will be updated to contain a summary of | 
|  | major changes with each release, and to mention important configuration or | 
|  | command syntax changes during development. | 
|  |  | 
|  | The list of older changes is below. | 
|  |  | 
|  | ================================================================================ | 
|  |  | 
|  | 21 May 2009 | 
|  |  | 
|  | * stat(2) files before trying to load them to avoid problems, for example | 
|  | with "source-file /dev/zero". | 
|  |  | 
|  | 19 May 2009 | 
|  |  | 
|  | * Try to guess if the window is UTF-8 by outputting a three-byte UTF-8 wide | 
|  | character and seeing how much the cursor moves. Currently tries to figure out | 
|  | if this works by some stupid checks on the terminal, these need to be | 
|  | rethought. Also might be better using a width 1 character rather than width 2. | 
|  | * If LANG contains "UTF-8", assume the terminal supports UTF-8, on the grounds | 
|  | that anyone who configures it probably wants UTF-8. Not certain if this is | 
|  | a perfect idea but let's see if it causes any problems. | 
|  | * New window option: monitor-content. Searches for a string in a window and if | 
|  | it matches, highlight the status line. | 
|  |  | 
|  | 18 May 2009 | 
|  |  | 
|  | * main-horizontal layout and main-pane-height option to match vertical. | 
|  | * New window option main-pane-width to set the width of the large left pane with | 
|  | main-vertical (was left-vertical) layout. | 
|  | * Lots of layout cleanup. manual layout is now manual-vertical. | 
|  |  | 
|  | 16 May 2009 | 
|  |  | 
|  | * select-layout command and a few default key bindings (M-0, M-1, M-2, M-9) to | 
|  | select layouts. | 
|  | * Recreate server socket on SIGUSR1, per SF feature request 2792533. | 
|  |  | 
|  | 14 May 2009 | 
|  |  | 
|  | * Keys in status line (p in vi mode, M-y in emacs) to paste the first line | 
|  | of the upper paste buffer. Suggested by Dan Colish. | 
|  | * clear-history command to clear a pane's history. | 
|  | * Don't force wrapping with \n when asked, let the cursor code figure it out. | 
|  | Should fix terminals which use this to detect line breaks. | 
|  | * Major cleanup and restructuring of build infrastructure. Still separate files | 
|  | for GNU and BSD make, but they are now hugely simplified at the expense of | 
|  | adding a configure script which must be run before make. Now build and | 
|  | install with: | 
|  |  | 
|  | $ ./configure && make && sudo make install | 
|  |  | 
|  | 04 May 2009 | 
|  |  | 
|  | * Use ACS line drawing characters for pane separator lines. | 
|  |  | 
|  | 30 April 2009 | 
|  |  | 
|  | * Support command sequences without a space before the semicolon, for example | 
|  | "neww; neww" now works as well as "neww ; neww". "neww;neww" is still an | 
|  | error. | 
|  | * previous-layout command. | 
|  | * Display the layout name in window lists. | 
|  | * Merge resize-pane-up and resize-pane-down into resize-pane with -U and -D | 
|  | flags. | 
|  |  | 
|  | 29 April 2009 | 
|  |  | 
|  | * Get rid of compat/vis.* - only one function was used which is easily | 
|  | replaced,and less compat code == good. | 
|  |  | 
|  | 27 April 2009 | 
|  |  | 
|  | * Avoid using the prompt history when the server is locked, and prevent any | 
|  | input entered from being added to the client's prompt history. | 
|  | * New command, confirm-before (alias confirm), which asks for confirmation | 
|  | before executing a command. Bound "&" and "x" by default to confirm-before | 
|  | "kill-window" and confirm-before "kill-pane", respectively. | 
|  |  | 
|  | 23 April 2009 | 
|  |  | 
|  | * Support NEL, yet another way of making newline. Fixes the output from some | 
|  | Gentoo packaging thing. Reported by someone on SF then logs that allowed a | 
|  | fix sent by tcunha. | 
|  | * Use the xenl terminfo flag to detect early-wrap terminals like the FreeBSD | 
|  | console. Many thanks for a very informative email from Christian Weisgerber. | 
|  |  | 
|  | 21 April 2009 | 
|  |  | 
|  | * tmux 0.8 released. | 
|  |  | 
|  | 17 April 2009 | 
|  |  | 
|  | * Remove the right number of characters from the buffer when escape then | 
|  | a cursor key (or other key prefixed by \033) is pressed. Reported by | 
|  | Stuart Henderson. | 
|  |  | 
|  | 03 April 2009 | 
|  |  | 
|  | * rotate-window command. -U flag (default) for up, -D flag for down. | 
|  |  | 
|  | 02 April 2009 | 
|  |  | 
|  | * Change scroll/pane redraws to only redraw the single pane affected rather | 
|  | than the entire window. | 
|  | * If redrawing the region would mean redrawing > half the pane, just schedule | 
|  | to redraw the entire window. Also add a flag to skip updating the window any | 
|  | further if it is scheduled to be redrawn. This has the effect of batching | 
|  | multiple redraws together. | 
|  |  | 
|  | 01 April 2009 | 
|  |  | 
|  | * Basic horizontal splitting and layout management. Still some redraw and other | 
|  | issues - particularly, don't mix with manual pane resizing, be careful when | 
|  | viewing from multiple clients and don't expect shell windows to redraw very | 
|  | well after the layout is changed; generally cycling the layout a few times | 
|  | will fix most problems. Getting this in for testing while I think about how | 
|  | to deal with manual mode. | 
|  |  | 
|  | Split window as normal and cycle the layouts with C-b space. Some of the | 
|  | layouts will work better when swap-pane comes along. | 
|  |  | 
|  | 31 March 2009 | 
|  |  | 
|  | * AIX port, thanks to cmihai for access to a box. Only tested on 6.1 with xlc | 
|  | 10.1 (make sure CC is set). Needs GNU make and probably ncurses (didn't try | 
|  | plain curses). Also won't build with DEBUG, so comment the FDEBUG=1 line in | 
|  | GNUmakefile. | 
|  | * Draw a vertical line on the right when the window size is less than the | 
|  | terminal size. This is partly to shake out any horizontal limit bugs on the | 
|  | way to horizontal splitting/pane tiling. Currently a bit slow since it has to | 
|  | do a lot of redrawing but hopefully that will improve as I get some better | 
|  | ideas for how to do it. | 
|  | * Fix remaining problems with copy and paste and UTF-8. | 
|  |  | 
|  | 28 March 2009 | 
|  |  | 
|  | * Better UTF-8 support, including combined characters. Unicode data is now | 
|  | stored as UTF-8 in a separate array, the code does a lookup into this every | 
|  | time it gets to a UTF-8 cell. Zero width characters are just appended onto | 
|  | the UTF-8 data for the previous cell. This also means that almost no bytes | 
|  | extra are wasted non-Unicode data (yay). | 
|  |  | 
|  | Still some oddities, such as copy mode skips over wide characters in a | 
|  | strange way, and the code could do with some tidying. | 
|  | * Key repeating is now a property of the key binding not of the command. | 
|  | Repeat is turned on when the key is bound with the -r flag to bind-key. | 
|  | next/previous-window no longer repeat by default as it turned out to annoy | 
|  | me. | 
|  |  | 
|  | 27 March 2009 | 
|  |  | 
|  | * Clear using ED when redrawing the screen. I foolishly assumed using spaces | 
|  | would be equivalent and terminals would pick up on this, but apparently not. | 
|  | This fixes copy and paste in xterm/rxvt. | 
|  | * Sockets in /tmp are now created in a subdirectory named, tmux-UID, eg | 
|  | tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a | 
|  | separate server, the new -L command line option should be used: this creates | 
|  | a socket in the same directory with a different name ("-L main" will create | 
|  | socket called "main"). -S should only be used to place the socket outside | 
|  | /tmp. This makes sockets a little more secure and a bit more convenient to | 
|  | use multiple servers. | 
|  |  | 
|  | 21 March 2009 | 
|  |  | 
|  | * New session flag "set-remain-on-exit" to set remain-on-exit flag for new | 
|  | windows created in that session (like "remain-by-default" used to do). Not | 
|  | perfectly happy about this, but until I can think of a good way to introduce | 
|  | it generically (maybe a set of options in the session) this will do. Fixes | 
|  | SF request 2527847. | 
|  |  | 
|  | 07 March 2009 | 
|  |  | 
|  | * Support for 88 colour terminals. | 
|  | * break-pane command to create a new window using an existing pane. | 
|  |  | 
|  | 02 March 2009 | 
|  |  | 
|  | * Make escape key timer work properly so escape+key can be used without | 
|  | lightning fast key presses. | 
|  |  | 
|  | 13 February 2009 | 
|  |  | 
|  | * Redo mode keys slightly more cleanly and apply them to command prompt | 
|  | editing. vi or emacs mode is controlled by the session option status-keys. | 
|  |  | 
|  | 12 February 2009 | 
|  |  | 
|  | * Looking up argv[0] is expensive, so just use p_comm for the window name which | 
|  | is good enough. Also increase name update time to 500 ms. | 
|  |  | 
|  | 11 February 2009 | 
|  |  | 
|  | * Only use ri when actually at the top of the screen; just move the cursor up | 
|  | otherwise. | 
|  | * FreeBSD's console wraps lines at $COLUMNS - 1 rather than $COLUMNS (the | 
|  | cursor can never be beyond $COLUMNS - 1) and does not appear to support | 
|  | changing this behaviour, or any of the obvious possibilities (turning off | 
|  | right margin wrapping, insert mode). This is irritating, most notably because | 
|  | it impossible to write to the very bottom-right of the screen without | 
|  | scrolling. To work around this, if built on FreeBSD and run with a "cons" | 
|  | $TERM, the bottom-right cell on the screen is omitted. | 
|  | * Emulate scroll regions (slowly) to support the few terminals which don't have | 
|  | it (some of which don't really have any excuse). | 
|  |  | 
|  | 10 February 2009 | 
|  |  | 
|  | * No longer redraw the status line every status-interval unless it has actually | 
|  | changed. | 
|  |  | 
|  | 08 February 2009 | 
|  |  | 
|  | * Don't treat empty arguments ("") differently when parsing configuration | 
|  | file/command prompt rather than command line. | 
|  | * tmux 0.7 released. | 
|  |  | 
|  | 03 February 2009 | 
|  |  | 
|  | * New command, copy-buffer (alias copyb), to copy a session paste buffer to | 
|  | another session. | 
|  |  | 
|  | 01 February 2009 | 
|  |  | 
|  | * The character pair #(command) may now contain (escaped) right parenthesis. | 
|  |  | 
|  | 30 January 2009 | 
|  |  | 
|  | * . now bound to "command-prompt 'move-window %%'" by default, from joshe. | 
|  |  | 
|  | 29 January 2009 | 
|  |  | 
|  | * Window options to set status line fg, bg and attributes for a single | 
|  | window. Options are: window-status-fg, window-status-bg, | 
|  | window-status-attr. Set to "default" to use the session status colours. | 
|  |  | 
|  | This allows quite neat things like: | 
|  |  | 
|  | $ cat ~/bin/xssh | 
|  | #!/bin/sh | 
|  |  | 
|  | if [ ! -z "$TMUX" ]; then | 
|  | case "$1" in | 
|  | natalya) | 
|  | tmux setw window-status-fg red >/dev/null | 
|  | ;; | 
|  | natasha) | 
|  | tmux setw window-status-fg yellow >/dev/null | 
|  | ;; | 
|  | esac | 
|  | fi | 
|  | ssh "$@" | 
|  | [ ! -z "$TMUX" ] && tmux setw -u window-status-fg >/dev/null | 
|  | $ alias ssh="~/bin/xssh" | 
|  |  | 
|  | * Support #(command) in status-left, and status-right, which is displayed as | 
|  | the first line of command's output (e.g. set -g status-right | 
|  | "#(whoami)@#(hostname -s)"). Commands with )s aren't supported. | 
|  |  | 
|  | 28 January 2009 | 
|  |  | 
|  | * Support mouse in copy mode to move cursor. Can't do anything else at the | 
|  | moment until other mouse modes are handled. | 
|  | * Better support for at least the most common variant of mouse input: parse it | 
|  | and adjust for different panes. Also support mouse in window/session choice | 
|  | mode. | 
|  |  | 
|  | 27 January 2009 | 
|  |  | 
|  | * Bring back the fancy window titles with session/window names: it is easy to | 
|  | work around problems with elinks (see FAQ). | 
|  | * -u flag to scroll-mode and copy-mode to start scrolled one page | 
|  | up. scroll-mode -u is bound to prefix,page-up (ppage) by default. | 
|  | * Allow status, mode and message attributes to be changed by three new options: | 
|  | status-attr, mode-attr, message-attr. A comma-separataed list is accepted | 
|  | containing: bright, dim, underscore, blink, reverse, hidden, italics, for | 
|  | example: | 
|  |  | 
|  | set -g status-attr bright,blink | 
|  |  | 
|  | From Josh Elsasser, thanks! | 
|  |  | 
|  | 26 January 2009 | 
|  |  | 
|  | * Be more clever about picking the right process to create the window name. | 
|  | * Don't balls up the terminal on UTF-8 combined characters. Don't support them | 
|  | properly either - they are just discarded for the moment. | 
|  |  | 
|  | 25 January 2009 | 
|  |  | 
|  | * load-buffer command | 
|  |  | 
|  | 23 January 2009 | 
|  |  | 
|  | * Use reverse colours rather than swapping fg and bg for message, mode and | 
|  | status line. This makes these usable on black and white terminals. | 
|  | * Better error messages when creating a session or window fails. | 
|  | * Oops. Return non-zero on error. Reported by Will Maier. | 
|  |  | 
|  | 21 January 2009 | 
|  |  | 
|  | * Handle SIGTERM (and kill-server which uses it), a bit more neatly - tidy | 
|  | up properly and print a nicer message. Same effect though :-). | 
|  | * new-window now supports -k to kill target window if it exists. | 
|  | * Bring back split-window -p and -l options to specify the height a percentage | 
|  | or as a number of lines. | 
|  | * Make window and session choice modes allow you to choose items in vi keys | 
|  | mode (doh!). As a side-effect, this makes enter copy selection (as well | 
|  | as C-w/M-w) when using emacs keys in copy mode. Reported by merdely. | 
|  |  | 
|  | 20 January 2009 | 
|  |  | 
|  | * Darwin support for automatic-rename from joshe; Darwin doesn't seem to have | 
|  | a sane method of getting argv[0] and searching for the precise insane way | 
|  | is too frustrating, so this just uses the executable name. | 
|  | * Try to change the window title to match the command running it in. This is | 
|  | done by reading argv[0] from the process group leader of the group that owns | 
|  | the tty (tcgetpgrp()). This can't be done portably so some OS-dependent code | 
|  | is introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment. | 
|  |  | 
|  | A new window flag, automatic-rename, is available: if this is set to off, the | 
|  | window name is not changed. Specifying a name with the new-window, | 
|  | new-session or rename-window commands will automatically set this flag to off | 
|  | for the window in question. To disable it entirely set the option to off | 
|  | globally (setw -g automatic-rename off). | 
|  |  | 
|  | 19 January 2009 | 
|  |  | 
|  | * Fix various stupid issues when the status line is turned off. Grr. | 
|  | * Use reverse attributes for clock and cursor, otherwise they do not | 
|  | appear on black and white terminals. | 
|  | * An error in a command sequence now stops execution of that sequence. | 
|  | Internally, each command code now passes a return code back rather than | 
|  | talking to the calling client (if any) directly. | 
|  | * attach-session now tries to start the server if it isn't already started - if | 
|  | no sessions are created in .tmux.conf this will cause an error. | 
|  | * Clean up starting server by making initial client get a special socketpair. | 
|  |  | 
|  | 18 January 2009 | 
|  |  | 
|  | * Unbreak UTF-8. | 
|  | * -a flag to next-window and previous-window to select the next or previous | 
|  | window with activity or bell. Bound to M-n and M-p. | 
|  | * find-window command to search window names, titles and visible content (but | 
|  | not history) for a string. If only one is found, the window is selected | 
|  | otherwise a choice list is shown. This (as with the other choice commands) | 
|  | only works from a key. Bound to "f" by default. | 
|  | * Cleaned up command printing code, also enclose arguments with spaces in "s. | 
|  | * Added command sequences. These are entered by separating each argument by a ; | 
|  | argument (spaces on both sides), for example: | 
|  |  | 
|  | lsk ; lsc | 
|  |  | 
|  | To use a literal ; as the argument prefix it with \, for example: | 
|  |  | 
|  | bind x lsk \; lsc | 
|  |  | 
|  | Commands are executed from left to right. Also note that command sequences do | 
|  | not support repeat-time repetition unless all commands making up the sequence | 
|  | support it. | 
|  | * suspend-client command to suspend a client. Don't try to background it | 
|  | though... | 
|  | * Mark attached sessions in sessions lists. Suggested by Simon Kuhnle. | 
|  |  | 
|  | 17 January 2009 | 
|  |  | 
|  | * tmux 0.6 released. | 
|  |  | 
|  | 15 January 2009 | 
|  |  | 
|  | * Support #H for hostname and #S for session name in status-left/right. | 
|  | * Two new commands, choose-window and choose-session which work only when bound | 
|  | to a key and allow the window or session to be selected from a list. These | 
|  | are now bound to "w" and "s" instead of the list commands. | 
|  |  | 
|  | 14 January 2009 | 
|  |  | 
|  | * Rework the prefix-time stuff. The option is now called repeat-time and | 
|  | defaults to 500 ms. It only applies to a small subset of commands, currently: | 
|  | up-pane, down-pane, next-window, previous-window, resize-pane-up, | 
|  | resize-pane-down. These are the commands for which it is obviously useful, | 
|  | having it for everything else was just bloody annoying. | 
|  | * The alt-up and alt-down keys now resize a pane by five lines at a time. | 
|  | * switch-pane is now select-pane and requires -p to select a pane. The | 
|  | "o" key binding is changed to down-pane. | 
|  | * up-pane and down-pane commands, bound to arrow up and down by default. | 
|  | * Multiple vertical window splitting. Minimum pane size is four lines, an | 
|  | (unhelpful) error will be shown if attempting to split a window with less | 
|  | that eight lines. If the window is resized, as many panes are shown as can | 
|  | fit without reducing them below four lines. There is (currently!) not a way | 
|  | to show a hidden pane without making the window larger. | 
|  |  | 
|  | Note the -p and -l options to split-window are now gone, these may reappear | 
|  | once I think them through again. | 
|  | * Server locking on inactivity (lock-after-time) is now disabled by default. | 
|  |  | 
|  | 13 January 2009 | 
|  |  | 
|  | * kill-pane command. | 
|  |  | 
|  | 12 January 2009 | 
|  |  | 
|  | * command-prompt now accepts a single argument, a template string. Any | 
|  | occurrences of %% in this string are replaced by whatever is entered at the | 
|  | prompt and the result is executed as a command. This allows things like (now | 
|  | bound by default): | 
|  |  | 
|  | bind , command-prompt "rename-window %%" | 
|  |  | 
|  | Or my favourite: | 
|  |  | 
|  | bind x command-prompt "split-window 'man %%'" | 
|  |  | 
|  | * Option to set prefix time, allowing multiple commands to be entered without | 
|  | pressing the prefix key again, so long as they each typed within this time of | 
|  | each other. | 
|  | * Yet more hacks for key handling. Think it is just about working now. | 
|  | * Two commands, resize-pane-up and resize-pane-down to resize a pane. | 
|  | * Make the window pane code handle panes of different sizes, and add a -l | 
|  | and -p arguments to split-window to specify the new window size in lines | 
|  | or as a percentage. | 
|  |  | 
|  | 11 January 2009 | 
|  |  | 
|  | * Vertical window splitting. Currently can only split a window into two panes. | 
|  | New split-window command splits (bound to ") and switch-pane command (bound to | 
|  | o) switches between panes. | 
|  |  | 
|  | close-pane, swap-pane commands are to follow. Also to come are pane resizing, | 
|  | >2 panes, the ability to break a pane out to a full window and vice versa and | 
|  | possibly horizontal splitting. | 
|  |  | 
|  | Panes are subelements of windows rather than being windows in their own | 
|  | right. I tried to make them windows (so the splitting was at the session or | 
|  | client level) but this rapidly became very complex and invasive. So in the | 
|  | interests of having something working, I just made it so each window can have | 
|  | two child processes instead of one (and it still took me 12 hours straight | 
|  | coding). Now the concept is proven and much of the support code is there, | 
|  | this may change in future if more flexibility is needed. | 
|  | * save-buffer command, from Tiago Cunha. | 
|  |  | 
|  | 10 January 2009 | 
|  |  | 
|  | * New option, lock-after-time. If there is no activity in the period specified | 
|  | by this option (in seconds), tmux will lock the server. Default is 1800 (30 | 
|  | minutes), set to 0 to disable. | 
|  | * Server locking. Two new commands: set-password to set a password (a | 
|  | preencrypted password may be specified with -c); and lock-server to lock the | 
|  | server until the password is entered. Also an additional command line flag, | 
|  | -U, to unlock from the shell. The default password is blank (any password | 
|  | accepted). If specifying an encrypted password from encrypt(1) in .tmux.conf | 
|  | with -c, don't forget to enclose it in single-quotes (') to prevent shell | 
|  | variable expansion. | 
|  | * If a window is created from the command line, tmux will now use the same | 
|  | current working directory for the new process. A new default-path option to | 
|  | sets the working directory for processes created from keys or interactively | 
|  | from the prompt. | 
|  | * New mode to display a large clock. Entered with clock-mode command (bound to | 
|  | C-b t by default); two window options: clock-mode-colour and clock-mode-style | 
|  | (12 or 24). This will probably be used as the basis for window locking. | 
|  | * New command, server-info, to show some server information and terminal | 
|  | details. | 
|  |  | 
|  | 09 January 2009 | 
|  |  | 
|  | * Stop using ncurses variables and instead build a table of the codes we want | 
|  | into an array for each terminal type. This makes the code a little more | 
|  | untidy in places but gets rid of the awful global variables and calling | 
|  | setterm all the time, and shoves all the ncurses-dependent mess into a single | 
|  | file, tty-term.c. It also allows overriding single terminal codes, this is | 
|  | used to fix rxvt on some platforms (where it is missing dch) and in future | 
|  | may allow user customisation a la vim. | 
|  | * Update key handling code. Simplify, support ctrl properly and add a new | 
|  | window option (xterm-keys) to output xterm key codes including ctrl and, | 
|  | if available, alt and shift. | 
|  |  | 
|  | 08 January 2009 | 
|  |  | 
|  | * If built without DEBUG (the release versions), don't cause a fatal error if | 
|  | the grid functions notice an input error, just log and ignore the | 
|  | request. This might mean me getting shouted at less often when bugs kill | 
|  | long-running sessions, at least in release versions. | 
|  | * Hopefully fix cursor out-of-bounds checking when writing to grid. When I | 
|  | wrote the code I must have forgotten that the cursor can be one cell off the | 
|  | right of the screen (yes, I know), so there were number of out-of-bounds/ | 
|  | overflow problems. | 
|  |  | 
|  | 07 January 2009 | 
|  |  | 
|  | * New flag to set and setw, -u, to unset an option (allowing it to inherit from) | 
|  | the global options again. | 
|  | * Added more info messages for options changes. | 
|  | * A bit of tidying and reorganisation of options code. | 
|  |  | 
|  | 06 January 2009 | 
|  |  | 
|  | * Don't crash when backspacing if cursor is off the right of the screen, | 
|  | reported by David Chisnall. | 
|  | * Complete words at any point inside command in prompt, also use option name | 
|  | as well as command names. | 
|  | * Per-client prompt history of up to 100 items. | 
|  | * Use a splay tree for key bindings instead of an array. As a side-effect this | 
|  | sorts them when listed. | 
|  |  | 
|  | 22 December 2008 | 
|  |  | 
|  | * Use the right keys for home and end. | 
|  |  | 
|  | 20 December 2008 | 
|  |  | 
|  | * Add vim mode for tmux configuration file to examples/, from Tiago Cunha. | 
|  |  | 
|  | 15 December 2008 | 
|  |  | 
|  | * New command, source-file (alias source), to load a configuration | 
|  | file. Written by Tiago Cunha, many thanks. | 
|  |  | 
|  | 13 December 2008 | 
|  |  | 
|  | * Work around lack of dch. On Linux, the rxvt termcap doesn't have it (it is | 
|  | lying, but we can't really start disbelieving termcaps...). This is a bit | 
|  | horrible - I can see no way to do it without pretty much redrawing the whole | 
|  | line, but it works... | 
|  |  | 
|  | 10 December 2008 | 
|  |  | 
|  | * glibc's getopt(3) is useless: it is not POSIX compliant without jumping | 
|  | through non-portable hoops, and the method of resetting it is unclear (the | 
|  | man page on my system says set optind to 1, but other sources say 0). So, | 
|  | import OpenBSD's getopt_long.c into compat/ for use on Linux and use the | 
|  | clearly documented optreset = optind = 1 method. This fixes some strange | 
|  | issues with command parsing (getting the syntax wrong would prevent any | 
|  | further commands being parsed). | 
|  |  | 
|  | 06 December 2008 | 
|  |  | 
|  | * Bring set/setw/show/showw into line with other commands. This means that by | 
|  | default they now affect the current window (if any); the new -g flag must be | 
|  | passed to set the global options. This changes the behaviour of set/show and | 
|  | WILL BREAK CURRENT CONFIGURATIONS. | 
|  |  | 
|  | In summary, whether in the configuration file, the command prompt, or a key | 
|  | binding, use -g to set a global option, use -t to specify a particular window | 
|  | or session, or omit both to try and use the current window or session. | 
|  |  | 
|  | This makes set/show a bit of a pain but is the correct behaviour for | 
|  | setw/showw and is the same as every other command, so we can put up with a | 
|  | bit of pain for consistency. | 
|  | * Redo window options. They now work in the same way to session options with a | 
|  | global options set. showw/setw commands now have similar syntax to show/set | 
|  | (including the ability to use abbreviations). | 
|  |  | 
|  | PLEASE NOTE this includes the following configuration-breaking changes: | 
|  |  | 
|  | - remain-by-default is now GONE, use "setw -g remain-on-exit" to apply the | 
|  | global window option instead; | 
|  | - mode-keys is now a window option rather than session - use "setw [-g] | 
|  | mode-keys" instead of set. | 
|  |  | 
|  | There are also some additions: | 
|  |  | 
|  | - message-fg and message-bg session options to control status line message | 
|  | colours; | 
|  | - mode-fg and mode-bg window options to set colours in window modes such as | 
|  | copy mode. | 
|  |  | 
|  | The options code still a mess and now there is twice as much of it :-(. | 
|  |  | 
|  | 02 December 2008 | 
|  |  | 
|  | * Add support for including the window title in status-left or status-right | 
|  | strings by including the character pair "#T". This may be prefixed with | 
|  | a number to specify a maximum length, for example "#24T" to use at most | 
|  | 24 characters of the title. | 
|  | * Introduce two new options, status-left-length and status-right-length, | 
|  | control the maximum length of left and right components of the status bar. | 
|  | * elinks (and possibly others) bypass the terminal and talk directly to X to | 
|  | restore the window title when exiting. tmux can't know about this particular | 
|  | bit of stupidity so the title ends up strange - the prefix isn't terribly | 
|  | important and elinks is quite useful so just get rid of it. | 
|  |  | 
|  | 27 November 2008 | 
|  |  | 
|  | * Tweaks to support Dragonfly. | 
|  |  | 
|  | 17 November 2008 | 
|  |  | 
|  | * tmux 0.5 released. | 
|  |  | 
|  | 16 November 2008 | 
|  |  | 
|  | * New window option: "utf8"; this must be on (it is off by default) for UTF-8 | 
|  | to be parsed. The global/session option "utf8-default" controls the setting | 
|  | for new windows. | 
|  |  | 
|  | This means that by default tmux does not handle UTF-8. To use UTF-8 by | 
|  | default it is necessary to a) "set utf8-default on" in .tmux.conf b) start | 
|  | tmux with -u on any terminal which support UTF-8. | 
|  |  | 
|  | It seems a bit unnecessary for this to be a per-window option but that is | 
|  | the easiest way to do it, and it can't do any harm... | 
|  | * Enable default colours if op contains \033[39;49m, based on a report from | 
|  | fulvio ciriaco. | 
|  |  | 
|  | 12 November 2008 | 
|  |  | 
|  | * Keep stack of last windows rather than just most recent; based on a diff from | 
|  | joshe. | 
|  |  | 
|  | 04 November 2008 | 
|  |  | 
|  | * Don't try to redraw status line when showing a prompt or message; if it does, | 
|  | the status timer is never reset so it redraws on every loop. Spotted by | 
|  | joshe. | 
|  |  | 
|  | 09 October 2008 | 
|  |  | 
|  | * Translate 256 colours into 16 if 256 is not available, same as screen does. | 
|  | * Better support for OSC command (only to set window title now), and also | 
|  | support using APC for the same purpose (some Linux default shell profiles do | 
|  | this). | 
|  |  | 
|  | 25 September 2008 | 
|  |  | 
|  | * Large internal rewrite to better support 256 colours and UTF-8. Screen data | 
|  | is now stored as single two-way array of structures rather than as multiple | 
|  | separate arrays. Also simplified a lot of code. | 
|  |  | 
|  | Only external changes are three new flags, -2, -d and -u, which force tmux to | 
|  | assume the terminal supports 256 colours, default colours (useful for | 
|  | xterm-256color which lacks the AX flag), or UTF-8 respectively. | 
|  |  | 
|  | 10 September 2008 | 
|  |  | 
|  | * Split off colour conversion code from screen code. | 
|  |  | 
|  | 09 September 2008 | 
|  |  | 
|  | * Initial UTF-8 support. A bit ugly and with a limit of 4096 UTF-8 | 
|  | characters per window. | 
|  |  | 
|  | 08 September 2008 | 
|  |  | 
|  | * 256 colour support. tmux attempts to autodetect the terminal by looking | 
|  | both at what ncurses reports (usually wrong for xterm) and checking if | 
|  | the TERM contains "256col". For xterm TERM=xterm-256color is needed (as | 
|  | well as a build that support 256 colours); this seems to work for rxvt | 
|  | as well. On non-256 colour terminals, high colours are translated to white | 
|  | foreground and black background. | 
|  |  | 
|  | 28 August 2008 | 
|  |  | 
|  | * Support OS X/Darwin thanks to bsd-poll.c from OpenSSH. Also convert | 
|  | from clock_gettime(2) to gettimeofday(2) as OS X doesn't support the | 
|  | former; microsecond accuracy will have to be sufficient ;-). | 
|  |  | 
|  | 07 August 2008 | 
|  |  | 
|  | * Lose some unused/useless wrapper functions. | 
|  |  | 
|  | 25 July 2008 | 
|  |  | 
|  | * Shell variables may now be defined and used in configuration file. Define | 
|  | variables with: | 
|  |  | 
|  | VAR=1 | 
|  |  | 
|  | And use with: | 
|  |  | 
|  | renamew ${VAR} | 
|  | renamew "x${VAR}x" | 
|  |  | 
|  | Also some other fixes to make, for example, "abc""abc" work similarly to | 
|  | the shell. | 
|  |  | 
|  | 24 July 2008 | 
|  |  | 
|  | * Finally lose inconsistently-used SCREEN_DEF* defines. | 
|  | * If cursor mode is on, switch the arrow keys from \033[A to \033OA. | 
|  | * Support the numeric keypad in both application and numbers mode. This is | 
|  | different from screen which always keeps it in application mode. | 
|  |  | 
|  | 19 July 2008 | 
|  |  | 
|  | * Unbreak "set status" - tmux thought it was ambiguous, reported by rivo nurges. | 
|  |  | 
|  | 02 July 2008 | 
|  |  | 
|  | * Split vi and emacs mode keys into two tables and add an option (mode-keys) | 
|  | to select between them. Default is emacs, use, | 
|  |  | 
|  | tmux set mode-keys vi | 
|  |  | 
|  | to change to vi. | 
|  |  | 
|  | vi mode uses space to start selection, enter to copy selection and escape | 
|  | to clear selection. | 
|  |  | 
|  | 01 July 2008 | 
|  |  | 
|  | * Protocol versioning. Clients which identify as a different version from the | 
|  | server will be rejected. | 
|  | * tmux 0.4 released. | 
|  |  | 
|  | 29 June 2008 | 
|  |  | 
|  | * Zombie windows. These are not closed when the child process dies. May be | 
|  | set for a window with the new "remain-on-exit" option; the default setting | 
|  | of this flag for new windows may be set with the "remain-by-default" session | 
|  | option. | 
|  |  | 
|  | A window may be restarted with the respawn-window command: | 
|  |  | 
|  | respawn-window [-k] [command] | 
|  |  | 
|  | If -k is given, any existing process running in the window is killed; | 
|  | if command is omitted, the same command as when the window was first | 
|  | created is used. | 
|  |  | 
|  | 27 June 2008 | 
|  |  | 
|  | * Handle nonexistent session or client to -t properly. | 
|  |  | 
|  | 25 June 2008 | 
|  |  | 
|  | * select-prompt command to allow a window to be selected at a prompt. Only | 
|  | windows in the current session may be selected. Bound to ' by default. | 
|  | Suggested by merdely. | 
|  | * move-window command. Requested by merdely. | 
|  | * Support binding alt keys (prefixed with M-). Change default to use | 
|  | C- for ctrl keys (^ is still accepted as an alternative). | 
|  | * Slim down default key bindings: support lowercase only. | 
|  | * Handle escaped keys properly (parse eg \033b into a single key code) and | 
|  | use this to change copy mode next/previous work to M-f and M-b to match | 
|  | emacs. | 
|  |  | 
|  | 24 June 2008 | 
|  |  | 
|  | * Next word (C-n/w) and previous word (C-b/b) in copy mode. | 
|  |  | 
|  | 23 June 2008 | 
|  |  | 
|  | * list-commands command (alias lscm). | 
|  | * Split information about options into a table and use it to parse options | 
|  | on input (allowing abbreviations) and to print them with show-options | 
|  | (meaning that bell-action gets a proper string). This turned out a bit ugly | 
|  | though :-/. | 
|  |  | 
|  | 22 June 2008 | 
|  |  | 
|  | * Do not translate black and white into default if the terminal supports | 
|  | default colours. This was nice to force programs which didn't use default | 
|  | colours to be properly transparent in rxvt/aterm windows with a background | 
|  | image, but it causes trouble if someone redefines the default foreground and | 
|  | background (to have black on white or something). | 
|  |  | 
|  | 21 June 2008 | 
|  |  | 
|  | * Naive tab completion in the command prompt. This only completes command | 
|  | names if a) they are at the start of the text b) the cursor is at | 
|  | the end of the text c) the text contains no spaces. | 
|  | * Only attempt to set the title where TERM looks like an xterm (contains | 
|  | "xterm", "rxvt" or is "screen"). I hate this but I don't see a better way: | 
|  | setting the title actually kills some other terminals pretty much dead. | 
|  | * Strip padding out of terminfo(5) strings. Currently the padding is just | 
|  | ignored, this may need to be altered if there are any software terminals | 
|  | out there that actually need it. | 
|  |  | 
|  | 20 June 2008 | 
|  |  | 
|  | * buffer-limit option to set maximum size of buffer stack. Default is 9. | 
|  | * Initial buffer improvements. Each session has a stack of buffers and each | 
|  | buffer command takes a -b option to manipulate items on the stack. If -b | 
|  | is omitted, the top entry is used. The following commands are currently | 
|  | available: | 
|  |  | 
|  | set-buffer [-b index] [-t target-session] string | 
|  | paste-buffer [-d] [-b index] [-t target-window] | 
|  | delete-buffer [-b index] [-t target-session] | 
|  | show-buffers [-t target-session] | 
|  | show-buffer [-b index] [-t target-session] | 
|  |  | 
|  | -d to paste-buffer deletes the buffer after pasting it. | 
|  | * New option, display-time, sets the time status line messages stay on screen | 
|  | (unless a key is pressed). Set in milliseconds, default is 750 (0.75 seconds). | 
|  | The timer is only checked every 100 ms or so. | 
|  |  | 
|  | 19 June 2008 | 
|  |  | 
|  | * Use "status" consistently for status line option, and prefix for "prefix" key | 
|  | option. | 
|  | * Allow commands to be entered at a prompt. This is triggered with the | 
|  | command-prompt command, bound to : by default. | 
|  | * Show status messages properly, without blocking the server. | 
|  |  | 
|  | 18 June 2008 | 
|  |  | 
|  | * New option, set-titles. On by default, this attempts to set the window title | 
|  | using the \e]2;...\007 xterm code. | 
|  |  | 
|  | Note that elinks requires the STY environment variable (used by screen) to be | 
|  | set before it will set the window title. So, if you want window titles set by | 
|  | elinks, set STY before running it (any value will do). I can't do this for all | 
|  | windows since setting it to an invalid value breaks screen. | 
|  | * Show arrows at either end of status line when scrolled if more windows | 
|  | exist. Highlight the arrow if a hidden window has activity or bell. | 
|  | * Scroll the status line to show the current window if necessary. Also handle | 
|  | windows smaller than needed better (show a blank status line instead of | 
|  | hanging or crashing). | 
|  |  | 
|  | 17 June 2008 | 
|  |  | 
|  | * tmux 0.3 released. | 
|  |  | 
|  | 16 June 2008 | 
|  |  | 
|  | * Add some information messages when window options are changed, suggested by | 
|  | Mike Erdely. Also add a -q command-line option to suppress them. | 
|  | * show-window-options (showw) command. | 
|  |  | 
|  | 15 June 2008 | 
|  |  | 
|  | * show-options (show) command to show one or all options. | 
|  |  | 
|  | 14 June 2008 | 
|  |  | 
|  | * New window options: force-width and force-height. This will force a window | 
|  | to an arbitrary width and height (0 for the default unlimited). This is | 
|  | neat for emacs which doesn't have a sensible way to force hard wrapping at 80 | 
|  | columns. Also, don't try to be clever and use clr_eol when redrawing the | 
|  | whole screen, it causes trouble since the redraw functions are used to draw | 
|  | the blank areas too. | 
|  | * Clear the blank area below windows properly when they are smaller than client, | 
|  | also add an indicator line to show the vertical limit. | 
|  | * Don't die on empty strings in config file, reported by Will Maier. | 
|  |  | 
|  | 08 June 2008 | 
|  |  | 
|  | * Set socket mode +x if any sessions are attached and -x if not. | 
|  |  | 
|  | 07 June 2008 | 
|  |  | 
|  | * Make status-interval actually changeable. | 
|  |  | 
|  | 06 June 2008 | 
|  |  | 
|  | * New window option: aggressive-resize. Normally, windows are resized to the | 
|  | size of the smallest attached session to which they are linked. This means a | 
|  | window only changes size when sessions are detached or attached, or they are | 
|  | linked or unlinked from a session. This flag changes a window to be the size | 
|  | of the smallest attached session for which it is the current window - it is | 
|  | resized every time a session changes to it or away from it. This is nice for | 
|  | things that handle SIGWINCH well (like irssi) and bad for things like shells. | 
|  | * The server now exits when no sessions remain. | 
|  | * Fix bug with inserting characters with TERM=xterm-color. | 
|  |  | 
|  | 05 June 2008 | 
|  |  | 
|  | * Completely reorganise command parsing. Much more common code in cmd-generic.c | 
|  | and a new way of specifying windows, clients or sessions. Now, most commands | 
|  | take a -t argument, which specifies a client, a session, or a window target. | 
|  | Clients and sessions are given alone (sessions are fnmatch(3)d and | 
|  | clients currently not), windows are give by (client|session):index. For | 
|  | example, if a user is in session "1" window 0 on /dev/ttypi, these should all | 
|  | be equivalent: | 
|  |  | 
|  | tmux renamew newname			(current session and window) | 
|  | tmux renamew -t: newname		(current session and window) | 
|  | tmux renamew -t:0 newname		(current session, window 0) | 
|  | tmux renamew -t0 newname		(current session, window 0) | 
|  | tmux renamew -t1:0 newname		(session 1, window 0) | 
|  | tmux renamew -t1: newname		(session 1's current window) | 
|  | tmux renamew -t/dev/ttypi newname	(client /dev/ttypi's current | 
|  | session and window) | 
|  | tmux renamew -t/dev/ttypi: newname	(client /dev/ttypi's current | 
|  | session and window) | 
|  | tmux renamew -t/dev/ttypi:0 newname	(client /dev/ttypi's current | 
|  | session, window 0) | 
|  |  | 
|  | This does have some downsides, for example, having to use -t on selectw, | 
|  |  | 
|  | tmux selectw -t7 | 
|  |  | 
|  | is annoying. But then using non-flagged arguments would mean renaming the | 
|  | current window would need to be something like: | 
|  |  | 
|  | tmux renamew : newname | 
|  |  | 
|  | It might be better not to try and be so consistent; comments to the usual | 
|  | address ;-). | 
|  | * Infrastructure for printing arguments in list-keys output. Easy ones only for | 
|  | now. | 
|  |  | 
|  | 04 June 2008 | 
|  |  | 
|  | * Add some vi(1) key bindings in copy mode, and support binding ^[, ^\, ^] | 
|  | ^^ and ^_. Both from/prompted by Will Maier. | 
|  | * setw monitor-activity and set status without arguments now toggle the current | 
|  | value; suggested by merdely. | 
|  | * New command set-window-option (alias setw) to set the single current window | 
|  | option: monitor-activity to determine whether window activity is shown in | 
|  | the status bar for that window (default off). | 
|  | * Change so active/bell windows are inverted in status line. | 
|  | * Activity monitoring - window with activity are marked in status line. No | 
|  | way to disable this/filter windows yet. | 
|  | * Brought select-window command into line with everything else; it now uses | 
|  | -i for the window index. | 
|  | * Strings to display on the left and right of the status bar may now be set | 
|  | with the status-left and status-right options. These are passed through | 
|  | strftime(3) before being displayed. The status bar is automatically updated | 
|  | at an interval set by the status-interval option. The default is to display | 
|  | nothing on the left and the date and time on the left; the default update | 
|  | interval is 15 seconds. | 
|  |  | 
|  | 03 June 2008 | 
|  |  | 
|  | * Per session options. Setting options without specifying a session sets the | 
|  | global options as normal (global options are inherited by all sessions); | 
|  | passing -c or -s will set the option only for that session. | 
|  | * Because a client has a session attached, any command needing a session can | 
|  | take a client and use its session. So, anything that used to accept -s now | 
|  | accepts -c as well. | 
|  | * -s to specify session name now supports fnmatch(3) wildcards; if multiple | 
|  | sessions are found, or if no -s is specified, the most newly created is used. | 
|  | * If no command is specified, assume new-session. As a byproduct, clean up | 
|  | command default values into separate init functions. | 
|  | * kill-server command. | 
|  |  | 
|  | 02 June 2008 | 
|  |  | 
|  | * New command, start-server (alias "start"), to start the tmux server and do | 
|  | nothing else. This is good if you have a configuration file which creates | 
|  | windows or sessions (like me): in that case, starting the server the first | 
|  | time tmux new is run is bad since it creates a new session and window (as | 
|  | it is supposed to - starting the server is a side-effect). | 
|  |  | 
|  | Instead, I have a little script which does the equivalent of: | 
|  |  | 
|  | tmux has -s0 2>/dev/null || tmux start | 
|  | tmux attach -d -s0 | 
|  |  | 
|  | And I use it to start the server if necessary and attach to my primary | 
|  | session. | 
|  | * Basic configuration file in ~/.tmux.conf or specified with -f. This is file | 
|  | contains a set of tmux commands that are run the first time the server is | 
|  | started. The configuration commands are executed before any others, so | 
|  | if you have a configuration file that contains: | 
|  |  | 
|  | new -d | 
|  | neww -s0 | 
|  |  | 
|  | And you do the following without an existing server running: | 
|  |  | 
|  | tmux new | 
|  |  | 
|  | You will end up with two sessions, session 0 with two windows (created by | 
|  | the configuration file) and your client attached to session 1 with one | 
|  | window (created by the command-line command). I'm not completely happy with | 
|  | this, it seems a little non-obvious, but I haven't yet decided what to do | 
|  | about it. | 
|  |  | 
|  | There is no environment variable handling or other special stuff yet. | 
|  |  | 
|  | In the future, it might be nice to be able to have per-session configuration | 
|  | settings, probably by having conditionals in the file (so you could, for | 
|  | example, have commands to define a particular window layout that would only | 
|  | be invoked if you called tmux new -smysession and mysession did not already | 
|  | exist). | 
|  | * BIG CHANGE: -s and -c to specify session name and client name are now passed | 
|  | after the command rather than before it. So, for example: | 
|  |  | 
|  | tmux -s0 neww | 
|  |  | 
|  | Becomes: | 
|  |  | 
|  | tmux neww -s0 | 
|  |  | 
|  | This is to allow them to be used in the (forthcoming) configuration file | 
|  | THIS WILL BREAK ANY CURRENT SCRIPTS OR ALIASES USING -s OR -c. | 
|  |  | 
|  | 01 June 2008 | 
|  |  | 
|  | * Bug fix: don't die if -k passed to link-window and the destination doesn't | 
|  | exist. | 
|  | * New command, send-keys, will send a set of keys to a window. | 
|  |  | 
|  | 31 May 2008 | 
|  |  | 
|  | * Fix so tmux doesn't hang if the initial window fails for some reason. This | 
|  | was highlighted by problems on Darwin, thanks to Elias Pipping for the report | 
|  | and access to a test account. (tmux still won't work on Darwin since its | 
|  | poll(2) is broken.) | 
|  |  | 
|  | 02 January 2008 | 
|  |  | 
|  | * Don't attempt to reset the tty on exit if it has been closed externally. | 
|  |  | 
|  | 06 December 2007 | 
|  |  | 
|  | * Restore checks for required termcap entries and add a few more obvious | 
|  | emulations. | 
|  | * Another major reorganisation, this time of screen handling. A new set of | 
|  | functions, screen_write_*, are now used to write to a screen and a tty | 
|  | simultaneously. These are used by the input parser to update the base | 
|  | window screen and also by the different modes which now interpose their own | 
|  | screen. | 
|  |  | 
|  | 30 November 2007 | 
|  |  | 
|  | * Support \ek...\e\ to set window name. | 
|  |  | 
|  | 27 November 2007 | 
|  |  | 
|  | * Enable/disable mouse when asked, if terminal claims to support it. Mouse | 
|  | sequences are just passed through unaltered for the moment. | 
|  | * Big internal reorganisation. Rather than leaving control of the tty solely in | 
|  | the client and piping all data through a socket to it, change so that the | 
|  | server opens the tty again and reads and writes to it directly. This avoids | 
|  | a lot of buffering and copying. Also reorganise the redrawing stuff so that | 
|  | everything goes through screen_draw_* - this makes the code simpler, but | 
|  | still needs broken up more, and all the ways of writing to screens should be | 
|  | more consistent. | 
|  |  | 
|  | 26 November 2007 | 
|  |  | 
|  | * Rather than shifting up one line at a time once the history is full, | 
|  | shift by 10% of the history each time. This is faster. | 
|  | * Add ^A and ^E to copy mode to move to start-of-line/end-of-line. | 
|  |  | 
|  | 24 November 2007 | 
|  |  | 
|  | * Support for alt charset mode (VT100 graphics characters). | 
|  |  | 
|  | 23 November 2007 | 
|  |  | 
|  | * Mostly complete copy & paste. Copy mode entered with C-b [ (copy-mode | 
|  | command). In copy mode, arrow keys/page up/page down/hjkl/C-u/C-f navigate, | 
|  | space or C-space starts selection, and enter or C-w copies and (important!) | 
|  | exits copy mode. C-b ] (paste-buffer) pastes into current window. No | 
|  | extra utility keys (bol/eol/clear selection/etc), only one single buffer, | 
|  | and no buffer manipulation commands (clear/view/etc) yet. The code is also | 
|  | fugly :-(. | 
|  | * history-limit option to set maximum history. Does not apply retroactively to | 
|  | existing windows! Lines take up a variable amount of space, but a reasonable | 
|  | guess for an 80-column terminal is 250 KB per 1000 lines (of history used, | 
|  | an empty history takes no space). | 
|  |  | 
|  | 21 November 2007 | 
|  |  | 
|  | * Create every line as zero length and only expand it as data is written, | 
|  | rather than creating at full size immediately. | 
|  | * Make command output (eg list-keys) go to a scrollable window similar to | 
|  | scroll mode. | 
|  | * Redo screen redrawing so it is a) readable b) split into utility functions | 
|  | that can be used outside screen.c. Use these to make scroll mode only | 
|  | redraw what it has to which gets rid of irritating flickering status box and | 
|  | makes it much faster. | 
|  | * Full line width memory and horizontal scrolling in history. | 
|  | * Initial support for scroll history. = to enter scrolling mode, and then | 
|  | vi keys or up/down/pgup/pgdown to navigate. Q to exit. No horizontal history | 
|  | yet (need per-line sizes) and a few kinks to be worked out (resizing while in | 
|  | history mode will probably cause trouble). | 
|  |  | 
|  | 20 November 2007 | 
|  |  | 
|  | * Fix format string error with "must specify a client" message. Also | 
|  | sprinkle some printflike tags. | 
|  | * tmux 0.1 released. | 
|  |  | 
|  | 17 November 2007 | 
|  |  | 
|  | * (nicm) Add -k option to link-window to kill target window if it exists. | 
|  |  | 
|  | 16 November 2007 | 
|  |  | 
|  | * (nicm) Split in-client display into two columns. This is a hack but not a lot | 
|  | more so than that bit is already and it helps with lots of keys. | 
|  | * (nicm) switch-client command to switch client between different sessions. This | 
|  | is pretty cool: | 
|  |  | 
|  | $ tmux bind q switch 0 | 
|  | $ tmux bind w switch 1 | 
|  |  | 
|  | Then you can switch between sessions 0 and 1 with a key :-). | 
|  | * (nicm) Accept "-c client-tty" on command line to allow client manipulation | 
|  | commands, and change detach-/refresh-session to detach-/refresh-client (this | 
|  | loses the -a behaviour, but at some point -session versions may return, and | 
|  | -c will allow fnmatch(3)). | 
|  | * (nicm) List available commands on ambiguous command. | 
|  |  | 
|  | 12 November 2007 | 
|  |  | 
|  | * (nicm) If the terminal supports default colours (AX present), force black | 
|  | background and white foreground to default. This is useful on transparent | 
|  | *terms for programs which don't do it themselves (like most(1)). | 
|  | * (nicm) Fill in the rest of the man page. | 
|  | * (nicm) kill-session command. | 
|  |  | 
|  | 09 November 2007 | 
|  |  | 
|  | * (nicm) C-space is now "^ " not "^@". | 
|  | * (nicm) Support tab (\011). | 
|  | * (nicm) Initial man page outline. | 
|  | * (nicm) -V to show version. | 
|  | * (nicm) rename-session command. | 
|  |  | 
|  | 08 November 2007 | 
|  |  | 
|  | * (nicm) Check for required terminal capabilities on start. | 
|  |  | 
|  | 31 October 2007 | 
|  |  | 
|  | * (nicm) Linux port. | 
|  |  | 
|  | 30 October 2007 | 
|  |  | 
|  | * (nicm) swap-window command. Same as link-window but swaps windows. | 
|  |  | 
|  | 26 October 2007 | 
|  |  | 
|  | * (nicm) Saving scroll region on \e7 causes problems with ncmpc so I guess | 
|  | it is not required. | 
|  | * (nicm) unlink-window command. | 
|  | * (nicm) link-window command to link an existing window into another session | 
|  | (or another index in the same session). Syntax: | 
|  |  | 
|  | tmux -s dstname link-window [-i dstidx] srcname srcidx | 
|  |  | 
|  | * (nicm) Redo window data structures. The global array remains, but each per- | 
|  | session list is now a RB tree of winlink structures. This disassociates the | 
|  | window index from the array size (allowing arbitrary indexes) which still | 
|  | allowing windows to have multiple indexes. | 
|  |  | 
|  | 25 October 2007 | 
|  |  | 
|  | * (nicm) has-session command: checks if session exists. | 
|  |  | 
|  | 24 October 2007 | 
|  |  | 
|  | * (nicm) Support for \e6n to request cursor position. resize(1) now works. | 
|  | * (nicm) Support for \e7, \e8 save/restore cursor and attribute sequences. | 
|  | Currently don't save mode (probably should). Also change some cases where | 
|  | out-of-bound values are ignored to limit them to within range (there are | 
|  | others than need to be checked too). | 
|  |  | 
|  | 23 October 2007 | 
|  |  | 
|  | * (nicm) Lift limit on session name passed with -s. | 
|  | * (nicm) Show size in session/window lists. | 
|  | * (nicm) Pass tty up to server when client identifies and add a list-clients | 
|  | command to list connected clients. | 
|  |  | 
|  | 20 October 2007 | 
|  |  | 
|  | * (nicm) Add default-command option and change default to be $SHELL rather than | 
|  | $SHELL -l. Also try to read shell from passwd db if $SHELL isn't present. | 
|  |  | 
|  | 19 October 2007 | 
|  |  | 
|  | * (nicm) -n on new-session is now -s, and -n is now the initial window name. | 
|  | This was documented but not implemented :-/. | 
|  | * (nicm) kill-window command, bound to & by default (because it should be hard | 
|  | to hit accidently). | 
|  | * (nicm) bell-style option with three choices: "none" completely ignore bell; | 
|  | "any" pass through a bell in any window to current; "current" ignore bells | 
|  | except in current window. This applies only to the bell terminal signal, | 
|  | the status bar always reflects any bells. | 
|  | * (nicm) Refresh session command. | 
|  |  | 
|  | 12 October 2007 | 
|  |  | 
|  | * (nicm) Add a warning if $TMUX exists on new/attach. | 
|  | * (nicm) send-prefix command. Bound to C-b by default. | 
|  | * (nicm) set status, status-fg, status-bg commands. fg and bg are as a number | 
|  | from 0 to 8 or a string ("red", "blue", etc). status may be 1/0, on/off, | 
|  | yes/no. | 
|  | * (nicm) Make status line mark window in yellow on bell. | 
|  |  | 
|  | 04 October 2007 | 
|  |  | 
|  | * (nicm) -d option to attach to detach all other clients on the same session. | 
|  | * (nicm) Partial resizing support. Still buggy. A C-b S and back sometimes fixes | 
|  | it when it goes wonky. | 
|  | * (mxey) Added my tmux start script as an example (examples/start-tmux.sh). | 
|  | * (mxey) New sessions can now be given a command for their first window. | 
|  | * (mxey) Fixed usage statement for new-window. | 
|  | * (nicm) attach-session (can't believe I forgot it until now!) and list-windows | 
|  | commands. | 
|  | * (nicm) rename-window and select-window commands. | 
|  | * (nicm) set-option command (alias set): "tmux set-option prefix ^A". | 
|  | * (nicm) Key binding and unbinding is back. | 
|  |  | 
|  | 03 October 2007 | 
|  |  | 
|  | * (nicm) {new,next,last,previous}-window. | 
|  | * (nicm) Rewrite command handling so commands are much more generic and the | 
|  | same commands are used for command line and keys (although most will probably | 
|  | need to check how they are called). Currently incomplete (only new/detach/ls | 
|  | implemented). Change: -s is now passed before command again! | 
|  | * (nicm) String number arguments. So you can do: tmux bind ^Q create "blah". | 
|  | * (nicm) Key binding. tmux bind key command [argument] and tmux unbind key. | 
|  | Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A. | 
|  | Possible commands are in cmd.c (look at cmd_bind_table). | 
|  | * (nicm) Move command parsing into the client. Also rename some messages and | 
|  | tidy up a few bits. Lots more tidying up needed :-/. | 
|  |  | 
|  | 02 October 2007 | 
|  |  | 
|  | * (nicm) Redraw client status lines on rename. | 
|  | * (nicm) Error on ambiguous command. | 
|  |  | 
|  | 01 October 2007 | 
|  |  | 
|  | * (nicm) Restore window title handling. | 
|  | * (nicm) Simple uncustomisable status line with window list. | 
|  |  | 
|  | 30 September 2007 | 
|  |  | 
|  | * (nicm) Window info command for debugging, C-b I. | 
|  |  | 
|  | 29 September 2007 | 
|  |  | 
|  | * (nicm) Deleting/inserting lines should follow scrolling region. Fix. | 
|  | * (nicm) Allow creation of detached sessions: "tmux new-session -d". | 
|  | * (nicm) Permit error messages to be passed back for transient clients like | 
|  | rename. Also make rename -i work. | 
|  | * (nicm) Pass through bell in any window to current. | 
|  |  | 
|  | 28 September 2007 | 
|  |  | 
|  | * (nicm) Major rewrite of input parser: | 
|  | - Lose the old weirdness in favour of a state machine. | 
|  | - Merge in parsing from screen.c. | 
|  | - Split key parsing off into a separate file. | 
|  | This is step one towards hopefully allowing a status line. It requires | 
|  | that we output data as if the terminal had one line less than it really does - | 
|  | a serious problem when it comes to things like scrolling. This change | 
|  | consolidates all the range checking and limiting together which should make | 
|  | it easier. | 
|  | * (mxey) Added window renaming, like "tmux rename [-s session] [-i index] name" | 
|  |  | 
|  | 27 September 2007 | 
|  |  | 
|  | * Split "tmux list" into "tmux list-sessions" (ls) and "list-windows" (lsw). | 
|  | * New command session selection: | 
|  | - if name is specified, look for it and use it if it exists, otherwise | 
|  | error | 
|  | - if no name specified, try the current session from $TMUX | 
|  | - if $TMUX doesn't exist, and there is only one session, use it, | 
|  | otherwise error | 
|  |  | 
|  | 26 September 2007 | 
|  |  | 
|  | * Add command aliases, so "ls" is an alias for "list". | 
|  | * Rename some commands and alter syntax to take options after a la CVS. Also | 
|  | change some flags. So: | 
|  |  | 
|  | tmux -s/socket -nabc new | 
|  |  | 
|  | Becomes: | 
|  |  | 
|  | tmux -S/socket new -sabc | 
|  |  | 
|  | * Major tidy and split of client/server code. | 
|  |  | 
|  | 22 September 2007 | 
|  |  | 
|  | * Window list command (C-b W). Started by Maximilian Gass, finished by me. | 
|  |  | 
|  | 20 September 2007 | 
|  |  | 
|  | * Specify meta via environment variable (META). | 
|  | * Record last window and ^L key to switch to it. Largely from Maximilian Gass. | 
|  | * Reset ignored signals in child after forkpty, makes ^C work. | 
|  | * Wrap on next/previous. From Maximilian Gass. | 
|  |  | 
|  | 19 September 2007 | 
|  |  | 
|  | * Don't renumber windows on close. | 
|  |  | 
|  | 28 August 2007 | 
|  |  | 
|  | * Scrolling region (\e[r) support. | 
|  |  | 
|  | 27 August 2007 | 
|  |  | 
|  | * Change screen.c to work more logically and hopefully fix heap corruption. | 
|  |  | 
|  | 09 July 2007 | 
|  |  | 
|  | * Initial import to CVS. Basic functions are working, albeit with a couple of | 
|  | showstopper memory bugs and many missing features. Detaching, reattaching, | 
|  | creating new sessions, listing sessions work acceptably for using with shells. | 
|  | Simple curses programs (top, systat, tetris) and more complicated ones (mutt, | 
|  | emacs) that don't require scrolling regions (ESC[r) mostly work fine | 
|  | (including mutt, emacs). No status bar yet and no key remapping or other | 
|  | customisation. |
