1CHANGES FROM 3.5 TO 3.5a 2 3* Do not translate BSpace as Unicode with extended keys. 4 5* Fix so that keys with Shift are represented correctly with extended keys. 6 7* Revert to using /bin/sh for #() and run-shell and if-shell; the change to use 8 default-shell only applies now to popups. 9 10* Fix grey colour without a number suffix in styles. 11 12CHANGES FROM 3.4 TO 3.5 13 14* Revamp extended keys support to more closely match xterm and support mode 2 15 as well as mode 1. This is a substantial change to key handling which changes 16 tmux to always request mode 2 from parent terminal, changes to an unambiguous 17 internal representation of keys, and adds an option (extended-keys-format) to 18 control the format similar to the xterm(1) formatOtherKeys resource. 19 20* Clear an overlay (popup or menu) when command prompt is entered. 21 22* Add copy-mode -d flag to scroll a page down if in copy mode already (matching 23 -e). 24 25* Display hyperlinks in copy mode and add copy_cursor_hyperlink format to get 26 the hyperlink under the cursor. 27 28* Add a prefix timeout option. 29 30* Mouse move keys are not useful as key bindings because we do not turn them on 31 unless the application requests them. Ignore them so they do not cause the 32 prefix to be canceled 33 34* Add search_count and search_count_partial formats in copy mode. 35 36* Do not reset mouse pane if clicked on status line, 37 38* Add mirrored versions of the main-horizontal and main-vertical layouts where 39 the main pane is bottom or right instead of top or left. 40 41* Allow REP to work with Unicode characters. 42 43* Fix size calculation of terminators for clipboard escape sequences. 44 45* Treat CRLF as LF in config files where it is easy to do so. 46 47* The Linux console has some bugs with bright colours, so add some workarounds 48 for it. 49 50* If built with systemd, remove some environment variables it uses. 51 52* Adjust the logic when deleting last buffer to better preserve the selection: 53 if selecting the element below the deleted one fails (because as the last 54 one), select the one above it instead. 55 56* Add --enable-jemalloc to build with jemalloc memory allocator (since glibc 57 malloc is so poor). 58 59* Add a way (refresh-client -r) for control mode clients to provide OSC 10 and 60 11 responses to tmux so they can set the default foreground and background 61 colours. 62 63* Add N to search backwards in tree modes. 64 65* Use default-shell for command prompt, #() and popups. 66 67* Revert part of a change intended to improve search performance by skipping 68 parts of lines already searched, but which in fact skipped the ends of lines 69 altogether. 70 71* Add a command-error hook when a command fails. 72 73* Add an option allow-set-title to forbid applications from changing the pane 74 title. 75 76* Correct handling of mouse up events (don't ignore all but the last released 77 button), and always process down event for double click. 78 79* Fix a crash if focusing a pane that is exiting. 80 81* Pick newest session (as documented) when looking for next session for 82 detach-on-destroy. 83 84* Reduce default escape-time to 10 milliseconds. 85 86* Add display-menu -M to always turn mouse on in a menu. 87 88* Look for feature code 21 for DECSLRM and 28 for DECFRA in the device 89 attributes and also accept level 1. 90 91* Fix crash if built with SIXEL and the SIXEL colour register is invalid; also 92 remove SIXEL images before reflow. 93 94* Do not notify window-layout-changed if the window is about to be destroyed. 95 96* Do not consider a selection present if it is empty for the selection_active 97 and selection_present format variables. 98 99* Fix split-window -p. 100 101CHANGES FROM 3.3a TO 3.4 102 103* Add options keep-last and keep-group to destroy-unattached to keep the last 104 session whether in a group. 105 106* Don't allow paste-buffer into dead panes. 107 108* Add -t to source-file. 109 110* Rewrite combined character handling to be more consistent and to support 111 newer Unicode combined characters. 112 113* Add basic support for SIXEL if built with --enable-sixel. 114 115* Add a session, pane and user mouse range types for the status line and add 116 format variables for mouse_status_line and mouse_status_range so they can be 117 associated with different commands in the key bindings. 118 119* Add flag (-o) to next-prompt/previous-prompt to go to OSC 133 command output. 120 121* Add options and flags for menu styles (menu-style, menu-border-style) similar 122 to those existing for popups. 123 124* Add support for marking lines with a shell prompt based on the OSC 133 extension. 125 126* Check for libterminfo for NetBSD. 127 128* Add "us" to styles for underscore colour. 129 130* Add flags (-c and -y) to change the confirm key and default behaviour of 131 confirm-before. 132 133* Use ncurses' new tparm_s function (added in 6.4-20230424) instead of tparm so 134 it does not object to string arguments in c apabilities it doesn't already 135 know. Also ignore errors from tparm if using previous ncurses versions. 136 137* Set default lock command to vlock on Linux if present at build time. 138 139* Discard mouse sequences that have the right form but actually are invalid. 140 141* Add support for spawning panes in separate cgroups with systemd and a 142 configure flag (--disable-cgroups) to turn off. 143 144* Add a format (pane_unseen_changes) to show if there are unseen changes while 145 in a mode. 146 147* Remove old buffer when renaming rather than complaining. 148 149* Add an L modifier like P, W, S to loop over clients. 150 151* Add -f to list-clients like the other list commands. 152 153* Extend display-message to work for control clients. 154 155* Add a flag to display-menu to select the manu item selected when the menu is 156 open. 157 158* Have tmux recognise pasted text wrapped in bracket paste sequences, rather 159 than only forwarding them to the program inside. 160 161* Have client return 1 if process is interrupted to an input pane. 162 163* Query the client terminal for foreground and background colours and if OSC 10 164 or 11 is received but no colour has been set inside tmux, return the colour 165 from the first attached client. 166 167* Add send-keys -K to handle keys directly as if typed (so look up in key 168 table). 169 170* Process escape sequences in show-buffer. 171 172* Add a -l flag to display-message to disable format expansion. 173 174* Add paste-buffer-deleted notification and fix name of paste-buffer-changed. 175 176* Do not attempt to connect to the socket as a client if systemd is active. 177 178* Add scroll-top and scroll-bottom commands to scroll so cursor is at top or 179 bottom. 180 181* Add a -T flag to capture-pane to stop at the last used cell instead of the 182 full width. Restore the previous behaviour by making it default to off unless 183 -J is used. 184 185* Add message-line option to control where message and prompt go. 186 187* Notification when a paste buffer is deleted. 188 189* Add a Nobr terminfo(5) capability to tell tmux the terminal does not use bright 190 colours for bold. 191 192* Change g and G to go to top and bottom in menus. 193 194* Add a third state "all" to allow-passthrough to work even in invisible panes. 195 196* Add support for OSC 8 hyperlinks. 197 198* Store the time lines are scrolled into history and display in copy mode. 199 200* Add a %config-error reply to control mode for configuration file errors since 201 reporting them in view mode is useless. 202 203* A new feature flag (ignorefkeys) to ignore terminfo(5) function key 204 definitions for rxvt. 205 206* Pass through first argument to OSC 52 (which clipboards to set) if the 207 application provides it. 208 209* Expand arguments to send-keys, capture-pane, split-window, join-pane where it 210 makes sense to do so. 211 212* Ignore named buffers when choosing a buffer if one is not specified by the user. 213 214CHANGES FROM 3.3 TO 3.3a 215 216* Do not crash when run-shell produces output from a config file. 217 218* Do not unintentionally turn off all mouse mode when button mode is also 219 present. 220 221CHANGES FROM 3.2a TO 3.3 222 223* Add an ACL list for users connecting to the tmux socket. Users may be 224 forbidden from attaching, forced to attach read-only, or allowed to attach 225 read-write. A new command, server-access, configures the list. File system 226 permissions must still be configured manually. 227 228* Emit window-layout-changed on swap-pane. 229 230* Better error reporting when applying custom layouts. 231 232* Handle ANSI escape sequences in run-shell output. 233 234* Add pane_start_path to match start_command. 235 236* Set PWD so shells have a hint about the real path. 237 238* Do not allow pipe-pane on dead panes. 239 240* Do not report mouse positions (incorrectly) above the maximum of 223 in 241 normal mouse mode. 242 243* Add an option (default off) to control the passthrough escape sequence. 244 245* Support more mouse buttons when the terminal sends them. 246 247* Add a window-resized hook which is fired when the window is actually resized 248 which may be later than the client resize. 249 250* Add next_session_id format with the next session ID. 251 252* Add formats for client and server UID and user. 253 254* Add argument to refresh-client -l to forward clipboard to a pane. 255 256* Add remain-on-exit-format to set text shown when pane is dead. 257 258* With split-window -f use percentages of window size not pane size. 259 260* Add an option (fill-character) to set the character used for unused areas of 261 a client. 262 263* Add an option (scroll-on-clear) to control if tmux scrolls into history on 264 clear. 265 266* Add a capability for OSC 7 and use it similarly to how the title is set (and 267 controlled by the same set-titles option). 268 269* Add support for systemd socket activation (where systemd creates the Unix 270 domain socket for tmux rather than tmux creating it). Build with 271 --enable-systemd. 272 273* Add an option (pane-border-indicators) to select how the active pane is shown 274 on the pane border (colour, arrows or both). 275 276* Support underscore styles with capture-pane -e. 277 278* Make pane-border-format a pane option rather than window. 279 280* Respond to OSC 4 queries 281 282* Fix g/G keys in modes to do the same thing as copy mode (and vi). 283 284* Bump the time terminals have to respond to device attributes queries to three 285 seconds. 286 287* If automatic-rename is off, allow the rename escape sequence to set an empty 288 name. 289 290* Trim menu item text more intelligently. 291 292* Add cursor-style and cursor-colour options to set the default cursor style 293 and colour. 294 295* Accept some useful and non-conflicting emacs keys in vi normal mode at the 296 command prompt. 297 298* Add a format modifier (c) to force a colour to RGB. 299 300* Add -s and -S to display-popup to set styles, -b to set lines and -T to set 301 popup title. New popup-border-lines, popup-border-style and popup-style 302 options set the defaults. 303 304* Add -e flag to set an environment variable for a popup. 305 306* Make send-keys without arguments send the key it is bound to (if bound to a 307 key). 308 309* Try to leave terminal cursor at the right position even when tmux is drawing 310 its own cursor or selection (such as at the command prompt and in choose 311 mode) for people using screen readers and similar which can make use of it. 312 313* Change so that {} is converted to tmux commands immediately when parsed. This 314 means it must contain valid tmux commands. For commands which expand %% and 315 %%%, this now only happens within string arguments. Use of nested aliases 316 inside {} is now forbidden. Processing of commands given in quotes remains 317 the same. 318 319* Disable evports on SunOS since they are broken. 320 321* Do not expand the file given with tmux -f so it can contain :s. 322 323* Bump FORMAT_LOOP_LIMIT and add a log message when hit. 324 325* Add a terminal feature for the mouse (since FreeBSD termcap does not have kmous). 326 327* Forbid empty session names. 328 329* Improve error reporting when the tmux /tmp directory cannot be created or 330 used. 331 332* Give #() commands a one second grace period where the output is empty before 333 telling the user they aren't doing anything ("not ready"). 334 335* When building, pick default-terminal from the first of tmux-256color, tmux, 336 screen-256color, screen that is available on the build system (--with-TERM 337 can override). 338 339* Do not close popups on resize, instead adjust them to fit. 340 341* Add a client-active hook. 342 343* Make window-linked and window-unlinked window options. 344 345* Do not configure on macOS without the user making a choice about utf8proc 346 (either --enable-utf8proc or --disable-utf8proc). 347 348* Do not freeze output in panes when a popup is open, let them continue to 349 redraw. 350 351* Add pipe variants of the line copy commands. 352 353* Change copy-line and copy-end-of-line not to cancel and add -and-cancel 354 variants, like the other copy commands. 355 356* Support the OSC palette-setting sequences in popups. 357 358* Add a pane-colours array option to specify the defaults palette. 359 360* Add support for Unicode zero-width joiner. 361 362* Make newline a style delimiter as well so they can cross multiple lines for 363 readability in configuration files. 364 365* Change focus to be driven by events rather than scanning panes so the 366 ordering of in and out is consistent. 367 368* Add display-popup -B to open a popup without a border. 369 370* Add a menu for popups that can be opened with button three outside the popup 371 or on the left or top border. Resizing now only works on the right and bottom 372 borders or when using Meta. The menu allows a popup to be closed, expanded to 373 the full size of the client, centered in the client or changed into a pane. 374 375* Make command-prompt and confirm-before block by default (like run-shell). A 376 new -b flags runs them in the background as before. Also set return code for 377 confirm-before. 378 379* Change cursor style handling so tmux understands which sequences contain 380 blinking and sets the flag appropriately, means that it works whether cnorm 381 disables blinking or not. This now matches xterm's behaviour. 382 383* More accurate vi(1) word navigation in copy mode and on the status line. This 384 changes the meaning of the word-separators option: setting it to the empty 385 string is equivalent to the previous behavior. 386 387* Add -F for command-prompt and use it to fix "Rename" on the window menu. 388 389* Add different command histories for different types of prompts ("command", 390 "search" etc). 391 392CHANGES FROM 3.2 TO 3.2a 393 394* Add an "always" value for the "extended-keys" option; if set then tmux will 395 forward extended keys to applications even if they do not request them. 396 397* Add a "mouse" terminal feature so tmux can enable the mouse on terminals 398 where it is known to be supported even if terminfo(5) says otherwise. 399 400* Do not expand the filename given to -f so it can contain colons. 401 402* Fixes for problems with extended keys and modifiers, scroll region, 403 source-file, crosscompiling, format modifiers and other minor issues. 404 405CHANGES FROM 3.1c TO 3.2 406 407* Add a flag to disable keys to close a message. 408 409* Permit shortcut keys in buffer, client, tree modes to be configured with a 410 format (-K flag to choose-buffer, choose-client, choose-tree). 411 412* Add a current_file format for the config file being parsed. 413 414* When display-message used in config file, show the message after the config 415 file finishes. 416 417* Add client-detached notification in control mode. 418 419* Improve performance of format evaluation. 420 421* Make jump command support UTF-8 in copy mode. 422 423* Support X11 colour names and other colour formats for OSC 10 and 11. 424 425* Add "pipe" variants of "copy-pipe" commands which do not copy. 426 427* Include "focused" in client flags. 428 429* Send Unicode directional isolate characters around horizontal pane borders if 430 the terminal supports UTF-8 and an extension terminfo(5) capability "Bidi" is 431 present. 432 433* Add a -S flag to new-window to make it select the existing window if one 434 with the given name already exists rather than failing with an error. 435 436* Add a format modifier to check if a window or session name exists (N/w or 437 N/s). 438 439* Add compat clock_gettime for older macOS. 440 441* Add a no-detached choice to detach-on-destroy which detaches only if there 442 are no other detached sessions to switch to. 443 444* Add rectangle-on and rectangle-off copy mode commands. 445 446* Change so that window_flags escapes # automatically. A new format 447 window_raw_flags contains the old unescaped version. 448 449* Add -N flag to never start server even if command would normally do so. 450 451* With incremental search, start empty and only repeat the previous search if 452 the user tries to search again with an empty prompt. 453 454* Add a value for remain-on-exit that only keeps the pane if the program 455 failed. 456 457* Add a -C flag to run-shell to use a tmux command rather than a shell command. 458 459* Do not list user options with show-hooks. 460 461* Remove current match indicator in copy mode which can't work anymore since we 462 only search the visible region. 463 464* Make synchronize-panes a pane option and add -U flag to set-option to unset 465 an option on all panes. 466 467* Make replacement of ##s consistent when drawing formats, whether followed by 468 [ or not. Add a flag (e) to the q: format modifier to double up #s. 469 470* Add -N flag to display-panes to ignore keys. 471 472* Change how escaping is processed for formats so that ## and # can be used in 473 styles. 474 475* Add a 'w' format modifier for string width. 476 477* Add support for Haiku. 478 479* Expand menu and popup -x and -y as formats. 480 481* Add numeric comparisons for formats. 482 483* Fire focus events even when the pane is in a mode. 484 485* Add -O flag to display-menu to not automatically close when all mouse buttons 486 are released. 487 488* Allow fnmatch(3) wildcards in update-environment. 489 490* Disable nested job expansion so that the result of #() is not expanded again. 491 492* Use the setal capability as well as (tmux's) Setulc. 493 494* Add -q flag to unbind-key to hide errors. 495 496* Allow -N without a command to change or add a note to an existing key. 497 498* Add a -w flag to set- and load-buffer to send to clipboard using OSC 52. 499 500* Add -F to set-environment and source-file. 501 502* Allow colour to be spelt as color in various places. 503 504* Add n: modifier to get length of a format. 505 506* Respond to OSC colour requests if a colour is available. 507 508* Add a -d option to display-message to set delay. 509 510* Add a way for control mode clients to subscribe to a format and be notified 511 of changes rather than having to poll. 512 513* Add some formats for search in copy mode (search_present, search_match). 514 515* Do not wait on shutdown for commands started with run -b. 516 517* Add -b flags to insert a window before (like the existing -a for after) to 518 break-pane, move-window, new-window. 519 520* Make paste -p the default for ]. 521 522* Add support for pausing a pane when the output buffered for a control mode 523 client gets too far behind. The pause-after flag with a time is set on the 524 pane with refresh-client -f and a paused pane may be resumed with 525 refresh-client -A. 526 527* Allow strings in configuration files to span multiple lines - newlines and 528 any leading whitespace are removed, as well as any following comments that 529 couldn't be part of a format. This allows long formats or other strings to be 530 annotated and indented. 531 532* Instead of using a custom parse function to process {} in configuration 533 files, treat as a set of statements the same as outside {} and convert back 534 to a string as the last step. This means the rules are consistent inside and 535 outside {}, %if and friends work at the right time, and the final result 536 isn't littered with unnecessary newlines. 537 538* Add support for extended keys - both xterm(1)'s CSI 27 ~ sequence and the 539 libtickit CSI u sequence are accepted; only the latter is output. tmux will 540 only attempt to use these if the extended-keys option is on and it can detect 541 that the terminal outside supports them (or is told it does with the 542 "extkeys" terminal feature). 543 544* Add an option to set the pane border lines style from a choice of single 545 lines (ACS or UTF-8), double or heavy (UTF-8), simple (plain ASCII) or number 546 (the pane numbers). Lines that won't work on a non-UTF-8 terminal are 547 translated back into ACS when they are output. 548 549* Make focus events update the latest client (like a key press). 550 551* Store UTF-8 characters differently to reduce memory use. 552 553* Fix break-pane -n when only one pane in the window. 554 555* Instead of sending all data to control mode clients as fast as possible, add 556 a limit of how much data will be sent to the client and try to use it for 557 panes with some degree of fairness. 558 559* Add an active-pane client flag (set with attach-session -f, new-session -f 560 or refresh-client -f). This allows a client to have an independent active 561 pane for interactive use (the window client pane is still used for many 562 things however). 563 564* Add a mark to copy mode, this is set with the set-mark command (bound to X) 565 and appears with the entire line shown using copy-mode-mark-style and the 566 marked character in reverse. The jump-to-mark command (bound to M-x) swaps 567 the mark and the cursor positions. 568 569* Add a -D flag to make the tmux server run in the foreground and not as a 570 daemon. 571 572* Do not loop forever in copy mode when search finds an empty match. 573 574* Fix the next-matching-bracket logic when using vi(1) keys. 575 576* Add a customize mode where options may be browsed and changed, includes 577 adding a brief description of each option. Bound to C-b C by default. 578 579* Change message log (C-b ~) so there is one for the server rather than one per 580 client and it remains after detach, and make it useful by logging every 581 command. 582 583* Add M-+ and M-- to tree mode to expand and collapse all. 584 585* Change the existing client flags for control mode to apply for any client, 586 use the same mechanism for the read-only flag and add an ignore-size flag. 587 588 refresh-client -F has become -f (-F stays for backwards compatibility) and 589 attach-session and switch-client now have -f flags also. A new format 590 client_flags lists the flags and is shown by list-clients by default. 591 592 This separates the read-only flag from "ignore size" behaviour (new 593 ignore-size) flag - both behaviours are useful in different circumstances. 594 595 attach -r and switchc -r remain and set or toggle both flags together. 596 597* Store and restore cursor position when copy mode is resized. 598 599* Export TERM_PROGRAM and TERM_PROGRAM_VERSION like various other terminals. 600 601* Add formats for after hook command arguments: hook_arguments with all the 602 arguments together; hook_argument_0, hook_argument_1 and so on with 603 individual arguments; hook_flag_X if flag -X is present; hook_flag_X_0, 604 hook_flag_X_1 and so on if -X appears multiple times. 605 606* Try to search the entire history first for up to 200 ms so a search count can 607 be shown. If it takes too long, search the visible text only. 608 609* Use VIS_CSTYLE for paste buffers also (show \012 as \n). 610 611* Change default formats for tree mode, client mode and buffer mode to be more 612 compact and remove some clutter. 613 614* Add a key (e) in buffer mode to open the buffer in an editor. The buffer 615 contents is updated when the editor exits. 616 617* Add -e flag for new-session to set environment variables, like the same flag 618 for new-window. 619 620* Improve search match marking in copy mode. Two new options 621 copy-mode-match-style and copy-mode-current-match-style to set the style for 622 matches and for the current match respectively. Also a change so that if a 623 copy key is pressed with no selection, the current match (if any) is copied. 624 625* Sanitize session names like window names instead of forbidding invalid ones. 626 627* Check if the clear terminfo(5) capability starts with CSI and if so then 628 assume the terminal is VT100-like, rather than relying on the XT capability. 629 630* Improve command prompt tab completion and add menus both for strings and -t 631 and -s (when used without a trailing space). command-prompt has additional 632 flags for only completing a window (-W) and a target (-T), allowing C-b ' to 633 only show windows and C-b . only targets. 634 635* Change all the style options to string options so they can support formats. 636 Change pane-active-border-style to use this to change the border colour when 637 in a mode or with synchronize-panes on. This also implies a few minor changes 638 to existing behaviour: 639 640 - set-option -a with a style option automatically inserts a comma between the 641 old value and appended text. 642 643 - OSC 10 and 11 no longer set the window-style option, instead they store the 644 colour internally in the pane data and it is used as the default when the 645 option is evaluated. 646 647 - status-fg and -bg now override status-style instead of the option values 648 being changed. 649 650* Add extension terminfo(5) capabilities for margins and focus reporting. 651 652* Try $XDG_CONFIG_HOME/tmux/tmux.conf as well as ~/.config/tmux/tmux.conf for 653 configuration file (the search paths are in TMUX_CONF in Makefile.am). 654 655* Remove the DSR 1337 iTerm2 extension and replace by the extended device 656 attributes sequence (CSI > q) supported by more terminals. 657 658* Add a -s flag to copy-mode to specify a different pane for the source 659 content. This means it is possible to view two places in a pane's history at 660 the same time in different panes, or view the history while still using the 661 pane. Pressing r refreshes the content from the source pane. 662 663* Add an argument to list-commands to show only a single command. 664 665* Change copy mode to make copy of the pane history so it does not need to 666 freeze the pane. 667 668* Restore pane_current_path format from portable tmux on OpenBSD. 669 670* Wait until the initial command sequence is done before sending a device 671 attributes request and other bits that prompt a reply from the terminal. This 672 means that stray replies are not left on the terminal if the command has 673 attached and then immediately detached and tmux will not be around to receive 674 them. 675 676* Add a -f filter argument to the list commands like choose-tree. 677 678* Move specific hooks for panes to pane options and windows for window options 679 rather than all hooks being session options. These hooks are now window options: 680 681 window-layout-changed 682 window-linked 683 window-pane-changed 684 window-renamed 685 window-unlinked 686 687 And these are now pane options: 688 689 pane-died 690 pane-exited 691 pane-focus-in 692 pane-focus-out 693 pane-mode-changed 694 pane-set-clipboard 695 696 Any existing configurations using these hooks on a session rather than 697 globally (that is, set-hook or set-option without -g) may need to be changed. 698 699* Show signal names when a process exits with remain-on-exit on platforms which 700 have a way to get them. 701 702* Start menu with top item selected if no mouse and use mode-style for the 703 selected item. 704 705* Add a copy-command option and change copy-pipe and friends to pipe to it if 706 used without arguments, allows all the default copy key bindings to be 707 changed to pipe with one option rather than needing to change each key 708 binding individually. 709 710* Tidy up the terminal detection and feature code and add named sets of 711 terminal features, each of which are defined in one place and map to a 712 builtin set of terminfo(5) capabilities. Features can be specified based on 713 TERM with a new terminal-features option or with the -T flag when running 714 tmux. tmux will also detect a few common terminals from the DA and DSR 715 responses. 716 717 This is intended to make it easier to configure tmux's use of terminfo(5) 718 even in the presence of outdated ncurses(3) or terminfo(5) databases or for 719 features which do not yet have a terminfo(5) entry. Instead of having to grok 720 terminfo(5) capability names and what they should be set to in the 721 terminal-overrides option, the user can hopefully just give tmux a feature 722 name and let it do the right thing. 723 724 The terminal-overrides option remains both for backwards compatibility and to 725 allow tweaks of individual capabilities. 726 727* Support mintty's application escape sequence (means tmux doesn't have to 728 delay to wait for Escape, so no need to reduce escape-time when using 729 mintty). 730 731* Change so main-pane-width and height can be given as a percentage. 732 733* Support for the iTerm2 synchronized updates feature (allows the terminal to 734 avoid unnecessary drawing while output is still in progress). 735 736* Make the mouse_word and mouse_line formats work in copy mode and enable the 737 default pane menu in copy mode. 738 739* Add a -T flag to resize-pane to trim lines below the cursor, moving lines out 740 of the history. 741 742* Add a way to mark environment variables as "hidden" so they can be used by 743 tmux (for example in formats) but are not set in the environment for new 744 panes. set-environment and show-environment have a new -h flag and there is a 745 new %hidden statement for the configuration file. 746 747* Change default position for display-menu -x and -y to centre rather than top 748 left. 749 750* Add support for per-client transient popups, similar to menus but which are 751 connected to an external command (like a pane). These are created with new 752 command display-popup. 753 754* Change double and triple click bindings so that only one is fired (previously 755 double click was fired on the way to triple click). Also add default double 756 and triple click bindings to copy the word or line under the cursor and 757 change the existing bindings in copy mode to do the same. 758 759* Add a default binding for button 2 to paste. 760 761* Add -d flag to run-shell to delay before running the command and allow it to 762 be used without a command so it just delays. 763 764* Add C-g to cancel command prompt with vi keys as well as emacs, and q in 765 command mode. 766 767* When the server socket is given with -S, create it with umask 177 instead of 768 117 (because it may not be in a safe directory like the default directory in 769 /tmp). 770 771* Add a copy-mode -H flag to hide the position marker in the top right. 772 773* Add number operators for formats (+, -, *, / and m), 774 775CHANGED FROM 3.1b TO 3.1c 776 777* Do not write after the end of the array and overwrite the stack when 778 colon-separated SGR sequences contain empty arguments. 779 780CHANGES FROM 3.1a TO 3.1b 781 782* Fix build on systems without sys/queue.h. 783 784* Fix crash when allow-rename is on and an empty name is set. 785 786CHANGES FROM 3.1 TO 3.1a 787 788* Do not close stdout prematurely in control mode since it is needed to print 789 exit messages. Prevents hanging when detaching with iTerm2. 790 791CHANGES FROM 3.0a TO 3.1 792 793* Only search the visible part of the history when marking (highlighting) 794 search terms. This is much faster than searching the whole history and solves 795 problems with large histories. The count of matches shown is now the visible 796 matches rather than all matches. 797 798* Search using regular expressions in copy mode. search-forward and 799 search-backward use regular expressions by default; the incremental versions 800 do not. 801 802* Turn off mouse mode 1003 as well as the rest when exiting. 803 804* Add selection_active format for when the selection is present but not moving 805 with the cursor. 806 807* Fix dragging with modifier keys, so binding keys such as C-MouseDrag1Pane and 808 C-MouseDragEnd1Pane now work. 809 810* Add -a to list-keys to also list keys without notes with -N. 811 812* Do not jump to next word end if already on a word end when selecting a word; 813 fixes select-word with single character words and vi(1) keys. 814 815* Fix top and bottom pane calculation with pane border status enabled. 816 817* Add support for adding a note to a key binding (with bind-key -N) and use 818 this to add descriptions to the default key bindings. A new -N flag to 819 list-keys shows key bindings with notes. Change the default ? binding to use 820 this to show a readable summary of keys. Also extend command-prompt to return 821 the name of the key pressed and add a default binding (/) to show the note 822 for the next key pressed. 823 824* Add support for the iTerm2 DSR 1337 sequence to get the terminal version. 825 826* Treat plausible but invalid keys (like C-BSpace) as literal like any other 827 unrecognised string passed to send-keys. 828 829* Detect iTerm2 and enable use of DECSLRM (much faster with horizontally split 830 windows). 831 832* Add -Z to default switch-client command in tree mode. 833 834* Add ~ to quoted characters for %%%. 835 836* Document client exit messages in the manual page. 837 838* Do not let read-only clients limit the size, unless all clients are 839 read-only. 840 841* Add a number of new formats to inspect what sessions and clients a window is 842 present or active in. 843 844* Change file reading and writing to go through the client if necessary. This 845 fixes commands like "tmux loadb /dev/fd/X". Also modify source-file to 846 support "-" for standard input, like load-buffer and save-buffer. 847 848* Add ~/.config/tmux/tmux.conf to the default search path for configuration 849 files. 850 851* Bump the escape sequence timeout to five seconds to allow for longer 852 legitimate sequences. 853 854* Make a best effort to set xpixel and ypixel for each pane and add formats for 855 them. 856 857* Add push-default to status-left and status-right in status-format[0]. 858 859* Do not clear search marks on cursor movement with vi(1) keys. 860 861* Add p format modifier for padding to width and allow multiple substitutions 862 in a single format. 863 864* Add -f for full size to join-pane (like split-window). 865 866* Do not use bright when emulating 256 colours on an 8 colour terminal because 867 it is also bold on some terminals. 868 869* Make select-pane -P set window-active-style also to match previous behaviour. 870 871* Do not truncate list-keys output. 872 873* Turn automatic-rename back on if the \033k rename escape sequence is used 874 with an empty name. 875 876* Add support for percentage sizes for resize-pane ("-x 10%"). Also change 877 split-window and join-pane -l to accept similar percentages and deprecate the 878 -p flag. 879 880* Add -F flag to send-keys to expand formats in search-backward and forward 881 copy mode commands and copy_cursor_word and copy_cursor_line formats for word 882 and line at cursor in copy mode. Use for default # and * binding with vi(1) 883 keys. 884 885* Add formats for word and line at cursor position in copy mode. 886 887* Add formats for cursor and selection position in copy mode. 888 889* Support all the forms of RGB colour strings in OSC sequences rather than 890 requiring two digits. 891 892* Limit lazy resize to panes in attached sessions only. 893 894* Add an option to set the key sent by backspace for those whose system uses ^H 895 rather than ^?. 896 897* Change new-session -A without a session name (that is, no -s option also) to 898 attach to the best existing session like attach-session rather than a new 899 one. 900 901* Add a "latest" window-size option which tries to size windows based on the 902 most recently used client. This is now the default. 903 904* Add simple support for OSC 7 (result is available in the pane_path format). 905 906* Add push-default and pop-default for styles which change the colours and 907 attributes used for #[default]. These are used in status-format to restore 908 the behaviour of window-status-style being the default for 909 window-status-format. 910 911* Add window_marked_flag. 912 913* Add cursor-down-and-cancel in copy mode. 914 915* Default to previous search string for search-forward and search-backward. 916 917* Add -Z flag to rotate-window, select-pane, swap-pane, switch-client to 918 preserve zoomed state. 919 920* Add -N to capture-pane to preserve trailing spaces. 921 922* Add reverse sorting in tree, client and buffer modes. 923 924CHANGES FROM 3.0 TO 3.0a 925 926* Do not require REG_STARTEND. 927 928* Respawn panes or windows correctly if default-command is set. 929 930* Add missing option for after-kill-pane hook. 931 932* Fix for crash with a format variable that doesn't exist. 933 934* Do not truncate list-keys output on some platforms. 935 936* Do not crash when restoring a layout with only one pane. 937 938CHANGES FROM 2.9 TO 3.0 939 940* Workaround invalid layout strings generated by older tmux versions and add 941 some additional sanity checks 942 943* xterm 348 now disables margins when resized, so send DECLRMM again after 944 resize. 945 946* Add support for the SD (scroll down) escape sequence. 947 948* Expand arguments to C and s format modifiers to match the m modifier. 949 950* Add support for underscore colours (Setulc capability must be added with 951 terminal-overrides as described in tmux(1)). 952 953* Add a "fill" style attribute for the fill colour of the drawing area (where 954 appropriate). 955 956* New -H flag to send-keys to send literal keys. 957 958* Format variables for pane mouse modes (mouse_utf8_flag and mouse_sgr_flag) 959 and for origin mode (origin_flag). 960 961* Add -F to refresh-client for flags for control mode clients, only one flag 962 (no-output) supported at the moment. 963 964* Add a few vi(1) keys for menus. 965 966* Add pane options, set with set-option -p and displayed with show-options -p. 967 Pane options inherit from window options (so every pane option is also 968 a window option). The pane style is now configured by setting window-style 969 and window-active-style in the pane options; select-pane -P and -g now change 970 the option but are no longer documented. 971 972* Do not document set-window-option and show-window-options. set-option -w and 973 show-options -w should be used instead. 974 975* Add a -A flag to show-options to show parent options as well (they are marked 976 with a *). 977 978* Resize panes lazily - do not resize unless they are in an attached, active 979 window. 980 981* Add regular expression support for the format search, match and substitute 982 modifiers and make them able to ignore case. find-window now accepts -r to 983 use regular expressions. 984 985* Do not use $TMUX to find the session because for windows in multiple sessions 986 it is wrong as often as it is right, and for windows in one session it is 987 pointless. Instead use TMUX_PANE if it is present. 988 989* Do not always resize the window back to its original size after applying a 990 layout, keep it at the layout size until it must be resized (for example when 991 attached and window-size is not manual). 992 993* Add new-session -X and attach-session -x to send SIGHUP to parent when 994 detaching (like detach-client -P). 995 996* Support for octal escapes in strings (such as \007) and improve list-keys 997 output so it parses correctly if copied into a configuration file. 998 999* INCOMPATIBLE: Add a new {} syntax to the configuration file. This is a string 1000 similar to single quotes but also includes newlines and allows commands that 1001 take other commands as string arguments to be expressed more clearly and 1002 without additional escaping. 1003 1004 A literal { and } or a string containing { or } must now be escaped or 1005 quoted, for example '{' and '}' instead of { or }, or 'X#{foo}' instead of 1006 X#{foo}. 1007 1008* New <, >, <= and >= comparison operators for formats. 1009 1010* Improve escaping of special characters in list-keys output. 1011 1012* INCOMPATIBLE: tmux's configuration parsing has changed to use yacc(1). There 1013 is one incompatible change: a \ on its own must be escaped or quoted as 1014 either \\ or '\' (the latter works on older tmux versions). 1015 1016 Entirely the same parser is now used for parsing the configuration file 1017 and for string commands. This means that constructs previously only 1018 available in .tmux.conf, such as %if, can now be used in string commands 1019 (for example, those given to if-shell - not commands invoked from the 1020 shell, they are still parsed by the shell itself). 1021 1022* Add support for the overline attribute (SGR 53). The Smol capability is 1023 needed in terminal-overrides. 1024 1025* Add the ability to create simple menus. Introduces new command 1026 display-menu. Default menus are bound to MouseDown3 on the status line; 1027 MouseDown3 or M-MouseDown3 on panes; MouseDown3 in tree, client and 1028 buffer modes; and C-b < and >. 1029 1030* Allow panes to be empty (no command). They can be created either by piping to 1031 split-window -I, or by passing an empty command ('') to split-window. Output 1032 can be sent to an existing empty window with display-message -I. 1033 1034* Add keys to jump between matching brackets (emacs C-M-f and C-M-b, vi %). 1035 1036* Add a -e flag to new-window, split-window, respawn-window, respawn-pane to 1037 pass environment variables into the newly created process. 1038 1039* Hooks are now stored in the options tree as array options, allowing them to 1040 have multiple separate commands. set-hook and show-hooks remain but 1041 set-option and show-options can now also be used (show-options will only show 1042 hooks if given the -H flag). Hooks with multiple commands are run in index 1043 order. 1044 1045* Automatically scroll if dragging to create a selection with the mouse and the 1046 cursor reaches the top or bottom line. 1047 1048* Add -no-clear variants of copy-selection and copy-pipe which do not clear the 1049 selection after copying. Make copy-pipe clear the selection by default to be 1050 consistent with copy-selection. 1051 1052* Add an argument to copy commands to set the prefix for the buffer name, this 1053 (for example) allows buffers for different sessions to be named separately. 1054 1055* Update session activity on focus event. 1056 1057* Pass target from source-file into the config file parser so formats in %if 1058 and %endif have access to more useful variables. 1059 1060* Add the ability to infer an option type (server, session, window) from its 1061 name to show-options (it was already present in set-option). 1062 1063CHANGES FROM 2.9 TO 2.9a 1064 1065* Fix bugs in select-pane and the main-horizontal and main-vertical layouts. 1066 1067CHANGES FROM 2.8 TO 2.9 1068 1069* Attempt to preserve horizontal cursor position as well as vertical with 1070 reflow. 1071 1072* Rewrite main-vertical and horizontal and change layouts to better handle the 1073 case where all panes won't fit into the window size, reduce problems with 1074 pane border status lines and fix other bugs mostly found by Thomas Sattler. 1075 1076* Add format variables for the default formats in the various modes 1077 (tree_mode_format and so on) and add a -a flag to display-message to list 1078 variables with values. 1079 1080* Add a -v flag to display-message to show verbose messages as the format is 1081 parsed, this allows formats to be debugged 1082 1083* Add support for HPA (\033[`). 1084 1085* Add support for origin mode (\033[?6h). 1086 1087* No longer clear history on RIS. 1088 1089* Extend the #[] style syntax and use that together with previous format 1090 changes to allow the status line to be entirely configured with a single 1091 option. 1092 1093 Now that it is possible to configure their content, enable the existing code 1094 that lets the status line be multiple lines in height. The status option can 1095 now take a value of 2, 3, 4 or 5 (as well as the previous on or off) to 1096 configure more than one line. The new status-format array option configures 1097 the format of each line, the default just references the existing status-* 1098 options, although some of the more obscure status options may be eliminated 1099 in time. 1100 1101 Additions to the #[] syntax are: "align" to specify alignment (left, centre, 1102 right), "list" for the window list and "range" to configure ranges of text 1103 for the mouse bindings. 1104 1105 The "align" keyword can also be used to specify alignment of entries in tree 1106 mode and the pane status lines. 1107 1108* Add E: and T: format modifiers to expand a format twice (useful to expand the 1109 value of an option). 1110 1111* The individual -fg, -bg and -attr options have been removed; they 1112 were superseded by -style options in tmux 1.9. 1113 1114* Allow more than one mode to be opened in a pane. Modes are kept on a stack 1115 and retrieved if the same mode is entered again. Exiting the active mode goes 1116 back to the previous one. 1117 1118* When showing command output in copy mode, call it view mode instead (affects 1119 pane_mode format). 1120 1121* Add -b to display-panes like run-shell. 1122 1123* Handle UTF-8 in word-separators option. 1124 1125* New "terminal" colour allowing options to use the terminal default colour 1126 rather than inheriting the default from a parent option. 1127 1128* Do not move the cursor in copy mode when the mouse wheel is used. 1129 1130* Use the same working directory rules for jobs as new windows rather than 1131 always starting in the user's home. 1132 1133* Allow panes to be one line or column in size. 1134 1135* Go to last line when goto-line number is out of range in copy mode. 1136 1137* Yank previously cut text if any with C-y in the command prompt, only use the 1138 buffer if no text has been cut. 1139 1140* Add q: format modifier to quote shell special characters. 1141 1142* Add StatusLeft and StatusRight mouse locations (keys such as 1143 MouseDown1StatusLeft) for the status-left and status-right areas of the 1144 status line. 1145 1146* Add -Z to find-window. 1147 1148* Support for windows larger than the client. This adds two new options, 1149 window-size and default-size, and a new command, resize-window. The 1150 force-width and force-height options and the session_width and session_height 1151 formats have been removed. 1152 1153 The new window-size option tells tmux how to work out the size of windows: 1154 largest means it picks the size of the largest session, smallest the smallest 1155 session (similar to the old behaviour) and manual means that it does not 1156 automatically resize windows. aggressive-resize modifies the choice of 1157 session for largest and smallest as it did before. 1158 1159 If a window is in a session attached to a client that is too small, only part 1160 of the window is shown. tmux attempts to keep the cursor visible, so the part 1161 of the window displayed is changed as the cursor moves (with a small delay, 1162 to try and avoid excess redrawing when applications redraw status lines or 1163 similar that are not currently visible). 1164 1165 Drawing windows which are larger than the client is not as efficient as those 1166 which fit, particularly when the cursor moves, so it is recommended to avoid 1167 using this on slow machines or networks (set window-size to smallest or 1168 manual). 1169 1170 The resize-window command can be used to resize a window manually. If it is 1171 used, the window-size option is automatically set to manual for the window 1172 (undo this with "setw -u window-size"). resize-window works in a similar way 1173 to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a 1174 sets the window to the size of the smallest client (what it would be if 1175 window-size was smallest) and -A the largest. 1176 1177 For the same behaviour as force-width or force-height, use resize-window -x 1178 or -y. 1179 1180 If the global window-size option is set to manual, the default-size option is 1181 used for new windows. If -x or -y is used with new-session, that sets the 1182 default-size option for the new session. 1183 1184 The maximum size of a window is 10000x10000. But expect applications to 1185 complain and higher memory use if making a window that big. The minimum size 1186 is the size required for the current layout including borders. 1187 1188 The refresh-client command can be used to pan around a window, -U -D -L -R 1189 moves up, down, left or right and -c returns to automatic cursor 1190 tracking. The position is reset when the current window is changed. 1191 1192CHANGES FROM 2.7 TO 2.8 1193 1194* Make display-panes block the client until a pane is chosen or it 1195 times out. 1196 1197* Clear history on RIS like most other terminals do. 1198 1199* Add an "Any" key to run a command if a key is pressed that is not 1200 bound in the current key table. 1201 1202* Expand formats in load-buffer and save-buffer. 1203 1204* Add a rectangle_toggle format. 1205 1206* Add set-hook -R to run a hook immediately. 1207 1208* Add README.ja. 1209 1210* Add pane focus hooks. 1211 1212* Allow any punctuation as separator for s/x/y not only /. 1213 1214* Improve resizing with the mouse (fix resizing the wrong pane in some 1215 layouts, and allow resizing multiple panes at the same time). 1216 1217* Allow , and } to be escaped in formats as #, and #}. 1218 1219* Add KRB5CCNAME to update-environment. 1220 1221* Change meaning of -c to display-message so the client is used if it 1222 matches the session given to -t. 1223 1224* Fixes to : form of SGR. 1225 1226* Add x and X to choose-tree to kill sessions, windows or panes. 1227 1228CHANGES FROM 2.6 TO 2.7 1229 1230* Remove EVENT_* variables from environment on platforms where tmux uses them 1231 so they do not pass on to panes. 1232 1233* Fixes for hooks at server exit. 1234 1235* Remove SGR 10 (was equivalent to SGR 0 but no other terminal seems to do 1236 this). 1237 1238* Expand formats in window and session names. 1239 1240* Add -Z flag to choose-tree, choose-client, choose-buffer to automatically 1241 zoom the pane when the mode is entered and unzoom when it exits, assuming the 1242 pane is not already zoomed. This is now part of the default key bindings. 1243 1244* Add C-g to exit modes with emacs keys. 1245 1246* Add exit-empty option to exit server if no sessions (defaults to on). 1247 1248* Show if a filter is present in choose modes. 1249 1250* Add pipe-pane -I to to connect stdin of the child process. 1251 1252* Performance improvements for reflow. 1253 1254* Use RGB terminfo(5) capability to detect RGB colour terminals (the existing 1255 Tc extension remains unchanged). 1256 1257* Support for ISO colon-separated SGR sequences. 1258 1259* Add select-layout -E to spread panes out evenly (bound to E key). 1260 1261* Support wide characters properly when reflowing. 1262 1263* Pass PWD to new panes as a hint to shells, as well as calling chdir(). 1264 1265* Performance improvements for the various choose modes. 1266 1267* Only show first member of session groups in tree mode (-G flag to choose-tree 1268 to show all). 1269 1270* Support %else in config files to match %if; from Brad Town in GitHub issue 1271 1071. 1272 1273* Fix "kind" terminfo(5) capability to be S-Down not S-Up. 1274 1275* Add a box around the preview label in tree mode. 1276 1277* Show exit status and time in the remain-on-exit pane text; from Timo 1278 Boettcher in GitHub issue 1103. 1279 1280* Correctly use pane-base-index in tree mode. 1281 1282* Change the allow-rename option default to off. 1283 1284* Support for xterm(1) title stack escape sequences (GitHub issue 1075 from 1285 Brad Town). 1286 1287* Correctly remove padding cells to fix a UTF-8 display problem (GitHub issue 1288 1090). 1289 1290CHANGES FROM 2.5 TO 2.6, 05 October 2017 1291 1292* Add select-pane -T to set pane title. 1293 1294* Fix memory leak when lines with BCE are removed from history. 1295 1296* Fix (again) the "prefer unattached" behaviour of attach-session. 1297 1298* Reorder how keys are checked to allow keys to be specified that have a 1299 leading escape. GitHub issue 1048. 1300 1301* Support REP escape sequence (\033[b). 1302 1303* Run alert hooks based on options rather than always, and allow further bells 1304 even if there is an existing bell. 1305 1306* Add -d flag to display-panes to override display-panes-time. 1307 1308* Add selection_present format when in copy mode (allows key bindings that do 1309 something different if there is a selection). 1310 1311* Add pane_at_left, pane_at_right, pane_at_top and pane_at_bottom formats. 1312 1313* Make bell, activity and silence alerting more consistent by: removing the 1314 bell-on-alert option; adding activity-action and silence-action options with 1315 the same possible values as the existing bell-action; adding a "both" value 1316 for the visual-bell, visual-activity and visual-silence options to trigger 1317 both a bell and a message. 1318 1319* Add a pane_pipe format to show if pipe-pane is active. 1320 1321* Block signals between forking and resetting signal handlers so that the 1322 libevent signal handler doesn't get called in the child and incorrectly write 1323 into the signal pipe that it still shares with the parent. GitHub issue 1001. 1324 1325* Allow punctuation in pane_current_command. 1326 1327* Add -c for respawn-pane and respawn-window. 1328 1329* Wait for any remaining data to flush when a pane is closed while pipe-pane is 1330 in use. 1331 1332* Fix working out current client with no target. GitHub issue 995. 1333 1334* Try to fallback to C.UTF-8 as well as en_US.UTF-8 when looking for a UTF-8 1335 locale. 1336 1337* Add user-keys option for user-defined key escape sequences (mapped to User0 1338 to User999 keys). 1339 1340* Add pane-set-clipboard hook. 1341 1342* FAQ file has moved out of repository to online. 1343 1344* Fix problem with high CPU usage when a client dies unexpectedly. GitHub issue 1345 941. 1346 1347* Do a dance on OS X 10.10 and above to return tmux to the user namespace, 1348 allowing access to the clipboard. 1349 1350* Do not allow escape sequences which expect a specific terminator (APC, DSC, 1351 OSC) to wait for forever - use a small timeout. This reduces the chance of 1352 the pane locking up completely when sent garbage (cat /dev/random or 1353 similar). 1354 1355* Support SIGUSR2 to toggle logging on a running server, also generate the 1356 "out" log file with -vv not -vvvv. 1357 1358* Make set-clipboard a three state option: on (tmux both sends to outside 1359 terminal and accepts from applications inside); external (tmux sends outside 1360 but does not accept inside); and off. 1361 1362* Fix OSC 4 palette setting for bright foreground colours. GitHub issue 954. 1363 1364* Use setrgbf and setrgbb terminfo(5) capabilities to set RGB colours, if they 1365 are available. (Tc is still supported as well.) 1366 1367* Fix redrawing panes when they are resized several times but end up with the 1368 size unchanged (for example, splitw/resizep -Z/breakp). 1369 1370* Major rewrite of choose mode. Now includes preview, sorting, searching and 1371 tagging; commands that can be executed directly from the mode (for example, 1372 to delete one or more buffers); and filtering in tree mode. 1373 1374* choose-window and choose-session are now aliases of choose-tree (in the 1375 command-alias option). 1376 1377* Support OSC 10 and OSC 11 to set foreground and background colours. 1378 1379* Check the U8 capability to determine whether to use UTF-8 line drawing 1380 characters for ACS. 1381 1382* Some missing notifications for layout changes. 1383 1384* Control mode clients now do not affect session sizes until they issue 1385 refresh-client -C. new-session -x and -y works with control clients even if 1386 the session is not detached. 1387 1388* All new sessions that are unattached (whether with -d or started with no 1389 terminal) are now created with size 80 x 24. Whether the status line is on or 1390 off does not affect the size of new sessions until they are attached. 1391 1392* Expand formats in option names and add -F flag to expand them in option values. 1393 1394* Remember the search string for a pane even if copy mode is exited and entered 1395 again. 1396 1397* Some further BCE fixes (scroll up, reverse index). 1398 1399* Improvements to how terminals are cleared (entirely or partially). 1400 1401CHANGES FROM 2.4 TO 2.5, 09 May 2017 1402 1403* Reset updated flag when restarting #() command so that new output is properly 1404 recognised. GitHub issue 922. 1405 1406* Fix ECH with a background colour. 1407 1408* Do not rely on the terminal not moving the cursor after DL or EL. 1409 1410* Fix send-keys and send-prefix in copy-mode (so C-b C-b works). GitHub issue 1411 905. 1412 1413* Set the current pane for rotate-window so it works in command sequences. 1414 1415* Add pane_mode format. 1416 1417* Differentiate M-Up from Escape+Up when possible (that is, in terminals with 1418 xterm(1) style function keys). GitHub issue 907. 1419 1420* Add session_stack and window_stack_index formats. 1421 1422* Some new control mode notifications and corresponding hooks: 1423 pane-mode-changed, window-pane-changed, client-session-changed, 1424 session-window-changed. 1425 1426* Format pane_search_string for last search term while in copy mode (useful 1427 with command-prompt -I). 1428 1429* Fix a problem with high CPU usage and multiple clients with #(). GitHub issue 1430 889. 1431 1432* Fix UTF-8 combining characters in column 0. 1433 1434* Fix reference counting so that panes are properly destroyed and their 1435 processes killed. 1436 1437* Clamp SU (CSI S) parameter to work around a bug in Konsole. 1438 1439* Tweak line wrapping in full width panes to play more nicely with terminal 1440 copy and paste. 1441 1442* Fix when we emit SGR 0 in capture-pane -e. 1443 1444* Do not change TERM until after config file parsing has finished, so that 1445 commands run inside the config file can use it to make decisions (typically 1446 about default-terminal). 1447 1448* Make the initial client wait until config file parsing has finished to avoid 1449 racing with commands. 1450 1451* Fix core when if-shell fails. 1452 1453* Only use ED to clear screen if the pane is at the bottom. 1454 1455* Fix multibyte UTF-8 output. 1456 1457* Code improvements around target (-t) resolution. 1458 1459* Change how the default target (for commands without -t) is managed across 1460 command sequences: now it is set up at the start and commands are required 1461 to update it if needed. Fixes binding command sequences to mouse keys. 1462 1463* Make if-shell from the config file work correctly. 1464 1465* Change to always check the root key table if no binding is found in the 1466 current table (prefix table or copy-mode table or whatever). This means that 1467 root key bindings will take effect even in copy mode, if not overridden by a 1468 copy mode key binding. 1469 1470* Fix so that the history file works again. 1471 1472* Run config file without a client rather than using the first client, restores 1473 previous behaviour. 1474 1475* If a #() command doesn't exit, continue to read from it and use its last full 1476 line of output. 1477 1478* Handle slow terminals and fast output better: when the amount of data 1479 outstanding gets too large, discard output until it is drained and we are 1480 able to do a full redraw. Prevents tmux sitting on a huge buffer that the 1481 terminal will take forever to consume. 1482 1483* Do not redraw a client unless we realistically think it can accept the data - 1484 defer redraws until the client has nothing else waiting to write. 1485 1486CHANGES FROM 2.3 TO 2.4, 20 April 2017 1487 1488Incompatible Changes 1489==================== 1490 1491* Key tables have undergone major changes. Mode key tables are no longer 1492 separate from the main key tables. All mode key tables have been removed, 1493 together with the -t flag to bind-key and unbind-key. 1494 1495 The emacs-edit, vi-edit, emacs-choose and vi-choose tables have been replaced 1496 by fixed key bindings in the command prompt and choose modes. The mode-keys 1497 and status-keys options remain. 1498 1499 The emacs-copy and vi-copy tables have been replaced by the copy-mode and 1500 copy-mode-vi tables. Commands are sent using the -X and -N flags to 1501 send-keys. So the following: 1502 1503 bind -temacs-copy C-Up scroll-up 1504 bind -temacs-copy -R5 WheelUpPane scroll-up 1505 1506 Becomes: 1507 1508 bind -Tcopy-mode C-Up send -X scroll-up 1509 bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up 1510 1511 These changes allows the full command parser (including command sequences) and 1512 command set to be used - for example, the normal command prompt with editing 1513 and history is now used for searching, jumping, and so on instead of a custom 1514 one. The default C-r binding is now: 1515 1516 bind -Tcopy-mode C-r command-prompt -i -p'search up' "send -X search-backward-incremental '%%'" 1517 1518 There are also some new commands available with send -X, such as 1519 copy-pipe-and-cancel. 1520* set-remain-on-exit has gone -- can be achieved with hooks instead. 1521* Hooks: before hooks have been removed and only a selection of commands now 1522 have after hooks (they are no longer automatic). Additional hooks have been 1523 added. 1524* The xterm-keys option now defaults to on. 1525 1526Normal Changes 1527============== 1528 1529* Support for mouse double and triple clicks. 1530* BCE (Background Colour Erase) is now supported. 1531* All occurrences of a search string in copy mode are now highlighted; 1532 additionally, the number of search results is displayed. The highlighting 1533 updates interactively with the default emacs key bindings (incremental 1534 search). 1535* source-file now understands glob patterns. 1536* Formats now have simple comparisons: 1537 1538 #{==:a,b} 1539 #{!=:a,b} 1540 1541* There are the following new formats: 1542 1543 - #{version} -- the tmux server version; 1544 - #{client_termtype} -- the terminal type of the client; 1545 - #{client_name} -- the name of a client; 1546 - #{client_written} -- the number of bytes written to the client. 1547 1548* The configuration file now accepts %if/%endif conditional blocks which are 1549 processed when it is parsed; the argument is a format string (useful with the 1550 new format comparison options). 1551* detach-client now has -E to execute a command replacing the client instead of 1552 exiting. 1553* Add support for custom command aliases, this is an array option which 1554 contains items of the form "alias=command". This is consulted when an 1555 unknown command is parsed. 1556* break-pane now has -n to specify the new window name. 1557* OSC 52 support has been added for programs inside tmux to set a tmux buffer. 1558* The mouse "all event" mode (1003) is now supported. 1559* Palette setting is now possible (OSC 4 and 104). 1560* Strikethrough support (a recent terminfo is required). 1561* Grouped sessions can now be named (new -t). 1562* terminal-overrides and update-environment are now array options (the previous 1563 set -ag syntax should work without change). 1564* There have been substantial performance improvements. 1565 1566CHANGES FROM 2.2 TO 2.3, 29 September 2016 1567 1568Incompatible Changes 1569==================== 1570 1571None. 1572 1573Normal Changes 1574============== 1575 1576* New option 'pane-border-status' to add text in the pane borders. 1577* Support for hooks on commands: 'after' and 'before' hooks. 1578* 'source-file' understands '-q' to suppress errors for nonexistent files. 1579* Lots of UTF8 improvements, especially on MacOS. 1580* 'window-status-separator' understands #[] expansions. 1581* 'split-window' understands '-f' for performing a full-width split. 1582* Allow report count to be specified when using 'bind-key -R'. 1583* 'set -a' for appending to user options (@foo) is now supported. 1584* 'display-panes' can now accept a command to run, rather than always 1585 selecting the pane. 1586 1587CHANGES FROM 2.1 TO 2.2, 10 April 2016 1588 1589Incompatible Changes 1590==================== 1591 1592* The format strings which referenced time have been removed. Instead: 1593 1594 #{t:window_activity} 1595 1596can be used. 1597 1598* Support for TMPDIR has been removed. Use TMUX_TMPDIR instead. 1599* UTF8 detection now happens automatically if the client supports it, hence 1600 the: 1601 1602 mouse-utf8 1603 utf8 1604 1605 options has been removed. 1606* The: 1607 1608 mouse_utf8_flag 1609 1610 format string has been removed. 1611* The -I option to show-messages has been removed. See: 1612 1613 #{t:start_time} 1614 1615 format option instead. 1616 1617Normal Changes 1618============== 1619 1620* Panes are unzoomed with selectp -LRUD 1621* New formats added: 1622 1623 #{scroll_position} 1624 #{socket_path} 1625 #{=10:...} -- limit to N characters (from the start) 1626 #{=-10:...} -- limit to N characters (from the end) 1627 #{t:...} -- used to format time-based formats 1628 #{b:...} -- used to ascertain basename from string 1629 #{d:...} -- used to ascertain dirname from string 1630 #{s:...} -- used to perform substitutions on a string 1631 1632* Job output is run via the format system, so formats work again 1633* If display-time is set to 0, then the indicators wait for a key to be 1634 pressed. 1635* list-keys and list-commands can be run without starting the tmux server. 1636* kill-session learns -C to clear all alerts in all windows of the session. 1637* Support for hooks (internal for now), but hooks for the following have been 1638 implemented: 1639 1640 alert-bell 1641 alert-silence 1642 alert-activity 1643 client-attached 1644 client-detached 1645 client-resized 1646 pane-died 1647 pane-exited 1648 1649* RGB (24bit) colour support. The 'Tc' flag must be set in the external TERM 1650 entry (using terminal-overrides or a custom terminfo entry). 1651 1652CHANGES FROM 2.0 TO 2.1, 18 October 2015 1653 1654Incompatible Changes 1655==================== 1656 1657* Mouse-mode has been rewritten. There's now no longer options for: 1658 - mouse-resize-pane 1659 - mouse-select-pane 1660 - mouse-select-window 1661 - mode-mouse 1662 1663 Instead there is just one option: 'mouse' which turns on mouse support 1664 entirely. 1665* 'default-terminal' is now a session option. Furthermore, if this is set 1666 to 'screen-*' then emulate what screen does. If italics are wanted, this 1667 can be set to 'tmux' but this is still new and not necessarily supported 1668 on all platforms with older ncurses installs. 1669* The c0-* options for rate-limiting have been removed. Instead, a backoff 1670 approach is used. 1671 1672Normal Changes 1673============== 1674 1675* New formats: 1676 - session_activity 1677 - window_linked 1678 - window_activity_format 1679 - session_alerts 1680 - session_last_attached 1681 - client_pid 1682 - pid 1683* 'copy-selection', 'append-selection', 'start-named-buffer' now understand 1684 an '-x' flag to prevent it exiting copying mode. 1685* 'select-pane' now understands '-P' to set window/pane background colours. 1686* 'renumber-windows' now understands windows which are unlinked. 1687* 'bind' now understands multiple key tables. Allows for key-chaining. 1688* 'select-layout' understands '-o' to undo the last layout change. 1689* The environment is updated when switching sessions as well as attaching. 1690* 'select-pane' now understands '-M' for marking a pane. This marked pane 1691 can then be used with commands which understand src-pane specifiers 1692 automatically. 1693* If a session/window target is prefixed with '=' then only an exact match 1694 is considered. 1695* 'move-window' understands '-a'. 1696* 'update-environment' understands '-E' when attach-session is used on an 1697 already attached client. 1698* 'show-environment' understands '-s' to output Bourne-compatible commands. 1699* New option: 'history-file' to save/restore command prompt history. 1700* Copy mode is exited if the history is cleared whilst in copy-mode. 1701* 'copy-mode' learned '-e' to exit copy-mode when scrolling to end. 1702 1703CHANGES FROM 1.9a TO 2.0, 06 March 2015 1704 1705Incompatible Changes 1706==================== 1707 1708* The choose-list command has been removed. 1709* 'terminal-overrides' is now a server option, not a session option. 1710* 'message-limit' is now a server option, not a session option. 1711* 'monitor-content' option has been removed. 1712* 'pane_start_path' option has been removed. 1713* The "info" mechanism which used to (for some commands) provide feedback 1714 has been removed, and like other commands, they now produce nothing on 1715 success. 1716 1717Normal Changes 1718============== 1719 1720* tmux can now write an entry to utmp if the library 'utempter' is present 1721 at compile time. 1722* set-buffer learned append mode (-a), and a corresponding 1723 'append-selection' command has been added to copy-mode. 1724* choose-mode now has the following commands which can be bound: 1725 - start-of-list 1726 - end-of-list 1727 - top-line 1728 - bottom-line 1729 1730* choose-buffer now understands UTF-8. 1731* Pane navigation has changed: 1732 - The old way of always using the top or left if the choice is ambiguous. 1733 - The new way of remembering the last used pane is annoying if the 1734 layout is balanced and the leftmost is obvious to the user (because 1735 clearly if we go right from the top-left in a tiled set of four we want 1736 to end up in top-right, even if we were last using the bottom-right). 1737 1738 So instead, use a combination of both: if there is only one possible 1739 pane alongside the current pane, move to it, otherwise choose the most 1740 recently used of the choice. 1741* 'set-buffer' can now be told to give names to buffers. 1742* The 'new-session', 'new-window', 'split-window', and 'respawn-pane' commands 1743 now understand multiple arguments and handle quoting problems correctly. 1744* 'capture-pane' understands '-S-' to mean the start of the pane, and '-E-' to 1745 mean the end of the pane. 1746* Support for function keys beyond F12 has changed. The following explains: 1747 - F13-F24 are S-F1 to S-F12 1748 - F25-F36 are C-F1 to C-F12 1749 - F37-F48 are C-S-F1 to C-S-F12 1750 - F49-F60 are M-F1 to M-F12 1751 - F61-F63 are M-S-F1 to M-S-F3 1752 1753 Therefore, F13 becomes a binding of S-F1, etc. 1754* Support using pane id as part of session or window specifier (so % means 1755 session-of-%1 or window-of-%1) and window id as part of session 1756 (so @1 means session-of-@1). 1757* 'copy-pipe' command now understands formats via -F 1758* 'if-shell' command now understands formats via -F 1759* 'split-window' and 'join-window' understand -b to create the pane to the left 1760 or above the target pane. 1761 1762CHANGES FROM 1.9 TO 1.9a, 22 February 2014 1763 1764NOTE: This is a bug-fix release to address some important bugs which just 1765missed the 1.9 deadline, but were found afterwards. 1766 1767Normal Changes 1768============== 1769 1770* Fix crash due to uninitialized lastwp member of layout_cell 1771* Fix -fg/-bg/-style with 256 colour terminals. 1772 1773CHANGES FROM 1.8 TO 1.9, 20 February 2014 1774 1775NOTE: This release has bumped the tmux protocol version. It is therefore 1776advised that the prior tmux server is restarted when this version of tmux is 1777installed, to avoid protocol mismatch errors for newer clients trying to 1778talk to an older running tmux server. 1779 1780Incompatible Changes 1781==================== 1782 1783* 88 colour support has been removed. 1784* 'default-path' has been removed. The new-window command accepts '-c' to 1785 cater for this. The previous value of "." can be replaced with: 'neww -c 1786 $PWD', the previous value of '' which meant current path of the pane can 1787 be specified as: 'neww -c "#{pane_current_path}"' 1788 1789Deprecated Changes 1790================== 1791 1792* The single format specifiers: #A -> #Z (where defined) have been 1793 deprecated and replaced with longer-named equivalents, as listed in the 1794 FORMATS section of the tmux manpage. 1795* The various foo-{fg,bg,attr} commands have been deprecated and replaced 1796 with equivalent foo-style option instead. Currently this is still 1797 backwards-compatible, but will be removed over time. 1798 1799Normal Changes 1800============== 1801 1802* A new environment variable TMUX_TMPDIR is now honoured, allowing the 1803 socket directory to be set outside of TMPDIR (/tmp/ if not set). 1804* If -s not given to swap-pane the current pane is assumed. 1805* A #{pane_synchronized} format specifier has been added to be a conditional 1806 format if a pane is in a synchronised mode (c.f. synchronize-panes) 1807* Tmux now runs under Cygwin natively. 1808* Formats can now be nested within each other and expanded accordingly. 1809* Added 'automatic-rename-format' option to allow the automatic rename 1810 mechanism to use something other than the default of 1811 #{pane_current_command}. 1812* new-session learnt '-c' to specify the starting directory for that session 1813 and all subsequent windows therein. 1814* The session name is now shown in the message printed to the terminal when 1815 a session is detached. 1816* Lots more format specifiers have been added. 1817* Server race conditions have been fixed; in particular commands are not run 1818 until after the configuration file is read completely. 1819* Case insensitive searching in tmux's copy-mode is now possible. 1820* attach-session and switch-client learnt the '-t' option to accept a window 1821 and/or a pane to use. 1822* Copy-mode is only exited if no selection is in progress. 1823* Paste key in copy-mode is now possible to enter text from the clipboard. 1824* status-interval set to '0' now works as intended. 1825* tmux now supports 256 colours running under fbterm. 1826* Many bug fixes! 1827 1828CHANGES FROM 1.7 TO 1.8, 26 March 2013 1829 1830Incompatible Changes 1831==================== 1832 1833* layout redo/undo has been removed. 1834 1835Normal Changes 1836============== 1837 1838* Add halfpage up/down bindings to copy mode. 1839* Session choosing fixed to work with unattached sessions. 1840* New window options window-status-last-{attr,bg,fg} to denote the last 1841 window which was active. 1842* Scrolling in copy-mode now scrolls the region without moving the mouse 1843 cursor. 1844* run-shell learnt '-t' to specify the pane to use when displaying output. 1845* Support for middle-click pasting. 1846* choose-tree learns '-u' to start uncollapsed. 1847* select-window learnt '-T' to toggle to the last window if it's already 1848 current. 1849* New session option 'assume-paste-time' for pasting text versus key-binding 1850 actions. 1851* choose-* commands now work outside of an attached client. 1852* Aliases are now shown for list-commands command. 1853* Status learns about formats. 1854* Free-form options can be set with set-option if prepended with an '@' 1855 sign. 1856* capture-pane learnt '-p' to send to stdout, and '-e' for capturing escape 1857 sequences, and '-a' to capture the alternate screen, and '-P' to dump 1858 pending output. 1859* Many new formats added (client_session, client_last_session, etc.) 1860* Control mode, which is a way for a client to send tmux commands. 1861 Currently more useful to users of iterm2. 1862* resize-pane learnt '-x' and '-y' for absolute pane sizing. 1863* Config file loading now reports errors from all files which are loaded via 1864 the 'source-file' command. 1865* 'copy-pipe' mode command to copy selection and pipe the selection to a 1866 command. 1867* Panes can now emit focus notifications for certain applications 1868 which use those. 1869* run-shell and if-shell now accept formats. 1870* resize-pane learnt '-Z' for zooming a pane temporarily. 1871* new-session learnt '-A' to make it behave like attach-session. 1872* set-option learnt '-o' to prevent setting an option which is already set. 1873* capture-pane and show-options learns '-q' to silence errors. 1874* New command 'wait-for' which blocks a client until woken up again. 1875* Resizing panes will now reflow the text inside them. 1876* Lots and lots of bug fixes, fixing memory-leaks, etc. 1877* Various manpage improvements. 1878 1879CHANGES FROM 1.6 TO 1.7, 13 October 2012 1880 1881* tmux configuration files now support line-continuation with a "\" at the 1882 end of a line. 1883* New option status-position to move the status line to the top or bottom of 1884 the screen. 1885* Enforce history-limit option when clearing the screen. 1886* Give each window a unique id, like panes but prefixed with @. 1887* Add pane id to each pane in layout description (while still accepting 1888 the old form). 1889* Provide defined ways to set the various default-path possibilities: ~ 1890 for home directory, . for server start directory, - for session start 1891 directory and empty for the pane's working directory (the default). All 1892 can also be used as part of a relative path (eg -/foo). Also provide -c 1893 flags to neww and splitw to override default-path setting. 1894* Add -l flag to send-keys to send input literally (without translating 1895 key names). 1896* Allow a single option to be specified to show-options to show just that 1897 option. 1898* New command "move-pane" (like join-pane but allows the same window). 1899* join-pane and move-pane commands learn "-b" option to place the pane to 1900 the left or above. 1901* Support for bracketed-paste mode. 1902* Allow send-keys command to accept hex values. 1903* Add locking around "start-server" to avoid race-conditions. 1904* break-pane learns -P/-F arguments for display formatting. 1905* set-option learns "-q" to make it quiet, and not print out anything. 1906* copy mode learns "wrap-search" option. 1907* Add a simple form of output rate limiting by counting the number of 1908 certain C0 sequences (linefeeds, backspaces, carriage returns) and if it 1909 exceeds a threshold (current default 250/millisecond), start to redraw 1910 the pane every 100 milliseconds instead of making each change as it 1911 comes. Two configuration options - c0-change-trigger and 1912 c0-change-interval. 1913* find-window learns new flags: "-C", "-N", "-T" to match against either or 1914 all of a window's content, name, or title. Defaults to all three options 1915 if none specified. 1916* find-window automatically selects the appropriate pane for the found 1917 matches. 1918* show-environment can now accept one option to show that environment value. 1919* Exit mouse mode when end-of-screen reached when scrolling with the mouse 1920 wheel. 1921* select-layout learns -u and -U for layout history stacks. 1922* kill-window, detach-client, kill-session all learn "-a" option for 1923 killing all but the current thing specified. 1924* move-window learns "-r" option to renumber window sequentially in a 1925 session. 1926* New session option "renumber-windows" to automatically renumber windows in 1927 a session when a window is closed. (see "move-window -r"). 1928* Only enter copy-mode on scroll up. 1929* choose-* and list-* commands all use "-F" for format specifiers. 1930* When spawning external commands, the value from the "default-shell" option 1931 is now used, rather than assuming /bin/sh. 1932* New choose-tree command to render window/sessions as a tree for selection. 1933* display-message learns new format options. 1934* For linked-windows across sessions, all flags for that window are now 1935 cleared across sessions. 1936* Lots and lots of bug fixes, fixing memory-leaks, etc. 1937* Various manpage improvements. 1938 1939CHANGES FROM 1.5 TO 1.6, 23 January 2012 1940 1941* Extend the mode-mouse option to add a third choice which means the mouse 1942 does not enter copy mode. 1943* Add a -r flag to switch-client to toggle the client read-only flag. 1944* Add pane-base-index option. 1945* Support \ for line continuation in the configuration file. 1946* Framework for more powerful formatting of command output and use it for 1947 list-{panes,windows,sessions}. This allows more descriptive replacements 1948 (such as #{session_name}) and conditionals. 1949* Mark dead panes with some text saying they are dead. 1950* Reject $SHELL if it is not a full path. 1951* Add -S option to refresh-client to redraw status line. 1952* Add an else clause for if-shell. 1953* Try to resolve relative paths for loadb and saveb (first, using client 1954 working directory, if any, then default-path or session working directory). 1955* Support for \e[3J to clear the history and send the corresponding 1956 terminfo code (E3) before locking. 1957* When in copy mode, make repeat count indicate buffer to replace, if used. 1958* Add screen*:XT to terminal-overrides for tmux-in-tmux. 1959* Status-line message attributes added. 1960* Move word-separators to be a session rather than window option. 1961* Change the way the working directory for new processes is discovered. If 1962 default-path isn't empty, it is used. Otherwise, if a new window is created 1963 from the command-line, the working directory of the client is used. If not, 1964 platform specific code is used to retrieve the current working directory 1965 of the process in the active pane. If that fails, the directory where the 1966 session was created is used, instead. 1967* Do not change the current pane if both mouse-select-{pane,window} are 1968 enabled. 1969* Add \033[s and \033[u to save and restore cursor position. 1970* Allow $HOME to be used as default-path. 1971* Add CNL and CPL escape sequences. 1972* Calculate last position correctly for UTF-8 wide characters. 1973* Add an option allow-rename to disable the window rename escape sequence. 1974* Attributes for each type of status-line alert (ie bell, content and 1975 activity) added. Therefore, remove the superfluous options 1976 window-status-alert-{attr,bg,fg}. 1977* Add a -R flag to send-keys to reset the terminal. 1978* Add strings to allow the aixterm bright colours to be used when 1979 configuring colours. 1980* Drop the ability to have a list of keys in the prefix in favour of two 1981 separate options, prefix and prefix2. 1982* Flag -2 added to send-prefix to send the secondary prefix key. 1983* Show pane size in top right of display panes mode. 1984* Some memory leaks plugged. 1985* More command-prompt editing improvements. 1986* Various manpage improvements. 1987* More Vi mode improvements. 1988 1989CHANGES FROM 1.4 TO 1.5, 09 July 2011 1990 1991* Support xterm mouse modes 1002 and 1003. 1992* Change from a per-session stack of buffers to one global stack. This renders 1993 copy-buffer useless and makes buffer-limit now a server option. 1994* Fix most-recently-used choice by avoiding reset the activity timer for 1995 unattached sessions every second. 1996* Add a -P option to new-window and split-window to print the new window or 1997 pane index in target form (useful to pass it into other commands). 1998* Handle a # at the end of a replacement string (such as status-left) 1999 correctly. 2000* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262. 2001 If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all 2002 UTF-8 terminals. The option defaults to on if LANG etc are set in the same 2003 manner as the utf8 option. 2004* Support for HP-UX. 2005* Accept colours of the hex form #ffffff and translate to the nearest from the 2006 xterm(1) 256-colour set. 2007* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors 2008 before closing them (fixes things like "tmux ls && cat"). 2009* Use TMPDIR if set. 2010* Fix next and previous session functions to actually work. 2011* Support -x and -y for new-session to specify the initial size of the window 2012 if created detached with -d. 2013* Make bind-key accept characters with the top-bit-set and print them as octal. 2014* Set $TMUX without the session when background jobs are run. 2015* Simplify the way jobs work and drop the persist type, so all jobs are 2016 fire-and-forget. 2017* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the 2018 terminal disappears while locked. 2019* Add a -P option to detach to HUP the client's parent process (usually causing 2020 it to exit as well). 2021* Support passing through escape sequences to the underlying terminal by using 2022 DCS with a "tmux;" prefix. 2023* Prevent tiled producing a corrupt layout when only one column is needed. 2024* Give each pane created in a tmux server a unique id (starting from 0), put it 2025 in the TMUX_PANE environment variable and accept it as a target. 2026* Allow a start and end line to be specified for capture-pane which may be 2027 negative to capture part of the history. 2028* Add -a and -s options to lsp to list all panes in the server or session 2029 respectively. Likewise add -s to lsw. 2030* Change -t on display-message to be target-pane for the #[A-Z] replacements 2031 and add -c as target-client. 2032* The attach-session command now prefers the most recently used unattached 2033 session. 2034* Add -s option to detach-client to detach all clients attached to a session. 2035* Add -t to list-clients. 2036* Change window with mouse wheel over status line if mouse-select-window is on. 2037* When mode-mouse is on, automatically enter copy mode when the mouse is 2038 dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel 2039 is scrolled off the bottom. 2040* Provide #h character pair for short hostname (no domain). 2041* Don't use strnvis(3) for the title as it breaks UTF-8. 2042* Use the tsl and fsl terminfo(5) capabilities to update terminal title and 2043 automatically fill them in on terminals with the XT capability (which means 2044 their title setting is xterm-compatible). 2045* Add a new option, mouse-resize-pane. When on, panes may be resized by 2046 dragging their borders. 2047* Fix crash by resetting last pane on {break,swap}-pane across windows. 2048* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line. 2049* Support setting the xterm clipboard when copying from copy mode using the 2050 xterm escape sequence for the purpose (if xterm is configured to allow it). 2051* Support xterm(1) cursor colour change sequences through terminfo(5) Cc 2052 (set) and Cr (reset) extensions. 2053* Support DECSCUSR sequence to set the cursor style with two new terminfo(5) 2054 extensions, Cs and Csr. 2055* Make the command-prompt custom prompts recognize the status-left option 2056 character pairs. 2057* Add a respawn-pane command. 2058* Add a couple of extra xterm-style keys that gnome terminal provides. 2059* Allow the initial context on prompts to be set with the new -I option to 2060 command-prompt. Include the current window and session name in the prompt 2061 when renaming and add a new key binding ($) for rename session. 2062* Option bell-on-alert added to trigger the terminal bell when there is an 2063 alert. 2064* Change the list-keys format so that it shows the keys using actual tmux 2065 commands which should be able to be directly copied into the config file. 2066* Show full targets for lsp/lsw -a. 2067* Make confirm-before prompt customizable with -p option like command-prompt 2068 and add the character pairs #W and #P to the default kill-{pane,window} 2069 prompts. 2070* Avoid sending data to suspended/locked clients. 2071* Small memory leaks in error paths plugged. 2072* Vi mode improvements. 2073 2074CHANGES FROM 1.3 TO 1.4, 27 December 2010 2075 2076* Window bell reporting fixed. 2077* Show which pane is active in the list-panes output. 2078* Backoff reworked. 2079* Prevent the server from dying when switching into copy mode when already 2080 in a different mode. 2081* Reset running jobs when the status line is enabled or disabled. 2082* Simplify xterm modifier detection. 2083* Avoid crashing in copy mode if the screen size is too small for the 2084 indicator. 2085* Flags -n and -p added to switch-client. 2086* Use UTF-8 line drawing characters on UTF-8 terminals, thus fixing some 2087 terminals (eg putty) which disable the vt100 ACS mode switching sequences 2088 in UTF-8 mode. On terminals without ACS, use ASCII equivalents. 2089* New server option exit-unattached added. 2090* New session option destroy-unattached added. 2091* Fall back on normal session choice method if $TMUX exists but is invalid 2092 rather than rejecting. 2093* Mark repeating keys with "(repeat)" in the key list. 2094* When removing a pane, don't change the active pane unless the active pane 2095 is actually the one being removed. 2096* New command last-pane added. 2097* AIX fixes. 2098* Flag -a added to unbind-key. 2099* Add XAUTHORITY to update-environment. 2100* More info regarding window and pane flags is now shown in list-*. 2101* If VISUAL or EDITOR contains "vi" configure mode-keys and status-key to vi. 2102* New window option monitor-silence and session option visual-silence added. 2103* In the built-in layouts distribute the panes more evenly. 2104* Set the default value of main-pane-width to 80 instead of 81. 2105* Command-line flag -V added. 2106* Instead of keeping a per-client prompt history make it global. 2107* Fix rectangle copy to behave like emacs (the cursor is not part of the 2108 selection on the right edge but on the left it is). 2109* Flag -l added to switch-client. 2110* Retrieve environment variables from the global environment rather than 2111 getenv(3), thus allowing them to be updated during the configuration file. 2112* New window options other-pane-{height,width} added. 2113* More minor bugs fixed and manpage improvements. 2114 2115CHANGES FROM 1.2 TO 1.3, 18 July 2010 2116 2117* New input parser. 2118* Flags to move through panes -UDLR added to select-pane. 2119* Commands up-pane, and down-pane removed, since equivalent behaviour is now 2120 available through the target flag (-t:+ and -t:-). 2121* Jump-forward/backward in copy move (based on vi's F, and f commands). 2122* Make paste-buffer accept a pane as a target. 2123* Flag -a added to new-window to insert a window after an existing one, moving 2124 windows up if necessary. 2125* Merge more mode into copy mode. 2126* Run job commands explicitly in the global environment (which can be modified 2127 with setenv -g), rather than with the environment tmux started with. 2128* Use the machine's hostname as the default title, instead of an empty string. 2129* Prevent double free if the window option remain-on-exit is set. 2130* Key string conversions rewritten. 2131* Mark zombie windows as dead in the choose-window list. 2132* Tiled layout added. 2133* Signal handling reworked. 2134* Reset SIGCHLD after fork to fix problems with some shells. 2135* Select-prompt command removed. Therefore, bound ' to command-prompt -p index 2136 "select-window -t:%%" by default. 2137* Catch SIGHUP and terminate if running as a client, thus avoiding clients from 2138 being left hanging around when, for instance, a SSH session is disconnected. 2139* Solaris 9 fixes (such as adding compat {get,set}env(3) code). 2140* Accept none instead of default for attributes. 2141* Window options window-status-alert-{alert,bg,fg} added. 2142* Flag -s added to the paste-buffer command to specify a custom separator. 2143* Allow dragging to make a selection in copy mode if the mode-mouse option is 2144 set. 2145* Support the mouse scroll wheel. 2146* Make pipe-pane accept special character sequences (eg #I). 2147* Fix problems with window sizing when starting tmux from .xinitrc. 2148* Give tmux sockets (but not the containing folder) group permissions. 2149* Extend the target flags (ie -t) to accept an offset (for example -t:+2), and 2150 make it wrap windows, and panes. 2151* New command choose-buffer added. 2152* New server option detach-on-destroy to set what happens to a client when the 2153 session it is attached to is destroyed. If on (default), the client is 2154 detached. Otherwise, the client is switched to the most recently active of 2155 the remaining sessions. 2156* The commands load-buffer, and save-buffer now accept a dash (-) as the file 2157 to read from stdin, or write to stdout. 2158* Custom layouts added. 2159* Additional code reduction, bug fixes, and manpage enhancements. 2160 2161CHANGES FROM 1.1 TO 1.2, 10 March 2010 2162 2163* Switch to libevent. 2164* Emulate the ri (reverse index) capability, ergo allowing tmux to at least 2165 start on Sun consoles (TERM=sun, or sun-color). 2166* Assign each entry a number, or lowercase letter in choose mode, and accept 2167 that as a shortcut key. 2168* Permit top-bit-set characters to be entered in the status line. 2169* Mark no-prefix keys with (no prefix), rather than [] in list-keys. 2170* New command show-messages (alias showmsgs), and new session option 2171 message-limit, to show a per-client log of status lines messages up to the 2172 number defined by message-limit. 2173* Do not interpret #() for display-message to avoid leaking commands. 2174* New window options window-status-format, and window-status-current-format to 2175 control the format of each window in the status line. 2176* Add a -p flag to display-message to print the output, instead of displaying 2177 it in the status line. 2178* Emulate il1, dl1, ich1 to run with vt100 feature set. 2179* New command capture-pane (alias capturep) to copy the entire pane contents 2180 to a paste buffer. 2181* Avoid duplicating code by adding a -w flag to set-option, and show-options to 2182 set, and show window options. The commands set-window-option, and 2183 show-window-options are now aliases. 2184* Panes can now be referred to as top, bottom, top-left, etc. 2185* Add server-wide options, which can be set with set-option -s, and shown with 2186 show-options -s. 2187* New server option quiet (like -q from the command line). 2188* New server option escape-time to set the timeout used to detect if escapes 2189 are alone, part of a function key, or meta sequence. 2190* New session options pane-active-border-bg, pane-active-border-fg, 2191 pane-border-bg, and pane-border-fg to set pane colours. 2192* Make split-window accept a pane target, instead of a window. 2193* New command join-pane (alias joinp) to split, and move an existing pane into 2194 the space (the opposite of break-pane), thus simplifying calls to 2195 split-window, followed by move-window. 2196* Permit S- prefix on keys for shift when the terminal/terminfo supports them. 2197* Window targets (-t flag) can now refer to the last window (!), next (+), and 2198 previous (-) window by number. 2199* Mode keys to jump to the bottom/top of history, end of the next word, scroll 2200 up/down, and reverse search in copy mode. 2201* New session option display-panes-active-colour to display the active pane in 2202 a different colour with the display-panes command. 2203* Read the socket path from $TMUX if it's present, and -L, and -S are not 2204 given. 2205* Vi-style mode keys B, W, and E to navigate between words in copy mode. 2206* Start in more mode when configuration file errors are detected. 2207* Rectangle copy support added. 2208* If attach-session was specified with the -r flag, make the client read-only. 2209* Per-window alternate-screen option. 2210* Make load-buffer work with FIFOs. 2211* New window option word-separators to set the characters considered as word 2212 separators in copy mode. 2213* Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9] 2214 in vi mode, or M-[1-9] in emacs mode. 2215* utf8 improvements. 2216* As usual, additional code reduction, bug fixes, and manpage enhancements. 2217 2218CHANGES FROM 1.0 TO 1.1, 05 November 2009 2219 2220* New run-shell (alias run) command to run an external command without a 2221 window, capture it's stdout, and send it to output mode. 2222* Ability to define multiple prefix keys. 2223* Internal locking mechanism removed. Instead, detach each client and run the 2224 external command specified in the new session option lock-command (by default 2225 lock -np), thus allowing the system password to be used. 2226* set-password command, and -U command line flag removed per the above change. 2227* Add support for -c command line flag to execute a shell command. 2228* New lock-client (alias lockc), and lock-session (alias locks) commands to 2229 lock a particular client, or all clients attached to a session. 2230* Support C-n/C-p/C-v/M-v with emacs keys in choice mode. 2231* Use : for goto line rather than g in vi mode. 2232* Try to guess which client to use when no target client was specified. Finds 2233 the current session, and if only one client is present, use it. Otherwise, 2234 return the most recently used client. 2235* Make C-Down/C-Up in copy mode scroll the screen down/up one line without 2236 moving the cursor. 2237* Scroll mode superseded by copy mode. 2238* New synchronize-panes window option to send all input to all other panes in 2239 the same window. 2240* New lock-server session option to lock, when off (on by default), each 2241 session when it has been idle for the lock-after-time setting. When on, the 2242 entire server locks when all sessions have been idle for their individual 2243 lock-after-time setting. 2244* Add support for grouped sessions which have independent name, options, 2245 current window, but where the linked windows are synchronized (ie creating, 2246 killing windows are mirrored between the sessions). A grouped session may be 2247 created by passing -t to new-session. 2248* New mouse-select-pane session option to select the current pane with the 2249 mouse. 2250* Queue, and run commands in the background for if-shell, status-left, 2251 status-right, and #() by starting each once every status-interval. Adds the 2252 capability to call some programs which would previously cause the server to 2253 hang (eg sleep/tmux). It also avoids running commands excessively (ie if used 2254 multiple times, it will be run only once). 2255* When a window is zombified and automatic-rename is on, append [dead] to the 2256 name. 2257* Split list-panes (alias lsp) off from list-windows. 2258* New pipe-pane (alias pipep) to redirect a pane output to an external command. 2259* Support for automatic-renames for Solaris. 2260* Permit attributes to be turned off in #[] by prefixing with no (eg nobright). 2261* Add H/M/L in vi mode, and M-R/M-r in emacs to move the cursor to the top, 2262 middle, and bottom of the screen. 2263* -a option added to kill-pane to kill all except current pane. 2264* The -d command line flag is now gone (can be replaced by terminal-overrides). 2265 Just use op/AX to detect default colours. 2266* input/tty/utf8 improvements. 2267* xterm-keys rewrite. 2268* Additional code reduction, and bug fixes. 2269 2270CHANGES FROM 0.9 TO 1.0, 20 September 2009 2271 2272* Option to alter the format of the window title set by tmux. 2273* Backoff for a while after multiple incorrect password attempts. 2274* Quick display of pane numbers (C-b q). 2275* Better choose-window, choose-session commands and a new choose-client command. 2276* Option to request multiple responses when using command-prompt. 2277* Improved environment handling. 2278* Combine wrapped lines when pasting. 2279* Option to override terminal settings (terminal-overrides). 2280* Use the full range of ACS characters for drawing pane separator lines. 2281* Customisable mode keys. 2282* Status line colour options, with embedded colours in status-left/right, and 2283 an option to centre the window list. 2284* Much improved layouts, including both horizontal and vertical splitting. 2285* Optional visual bell, activity and content indications. 2286* Set the utf8 and status-utf8 options when the server is started with -u. 2287* display-message command to show a message in the status line, by default some 2288 information about the current window. 2289* Improved current process detection on NetBSD. 2290* unlink-window -k is now the same as kill-window. 2291* attach-session now works from inside tmux. 2292* A system-wide configuration file, /etc/tmux.conf. 2293* A number of new commands in copy mode, including searching. 2294* Panes are now specified using the target (-t) notation. 2295* -t now accepts fnmatch(3) patterns and looks for prefixes. 2296* Translate \r into \n when pasting. 2297* Support for binding commands to keys without the prefix key 2298* Support for alternate screen (terminfo smcup/rmcup). 2299* Maintain data that goes off screen after reducing the window size, so it can 2300 be restored when the size is increased again. 2301* New if-shell command to test a shell command before running a tmux command. 2302* tmux now works as the shell. 2303* Man page reorganisation. 2304* Many minor additions, much code tidying and several bug fixes. 2305 2306CHANGES FROM 0.8 TO 0.9, 01 July 2009 2307 2308* Major changes to build infrastructure: cleanup of makefiles and addition 2309 of a configure script. 2310* monitor-content window option to monitor a window for a specific fnmatch(3) 2311 pattern. The find-window command also now accepts fnmatch(3) patterns. 2312* previous-layout and select-layout commands, and a main-horizontal layout. 2313* Recreate the server socket on SIGUSR1. 2314* clear-history command. 2315* Use ACS line drawing characters for pane separator lines. 2316* UTF-8 improvements, and code to detect UTF-8 support by looking at 2317 environment variables. 2318* The resize-pane-up and resize-pane-down commands are now merged together 2319 into a new resize-pane command with -U and -D flags. 2320* confirm-before command to request a yes/no answer before executing dangerous 2321 commands. 2322* Status line bug fixes, support for UTF-8 (status-utf8 option), and a key to 2323 paste from the paste buffer. 2324* Support for some additional escape sequences and terminal features, including 2325 better support for insert mode and tab stops. 2326* Improved window resizing behaviour, modelled after xterm. 2327* Some code reduction and a number of miscellaneous bug fixes. 2328 2329================================================================================ 2330 2331On 01 June 2009, tmux was imported into the OpenBSD base system. From this date 2332onward changes are logged as part of the normal CVS commit message to either 2333OpenBSD or SourceForge CVS. This file will be updated to contain a summary of 2334major changes with each release, and to mention important configuration or 2335command syntax changes during development. 2336 2337The list of older changes is below. 2338 2339================================================================================ 2340 234121 May 2009 2342 2343* stat(2) files before trying to load them to avoid problems, for example 2344 with "source-file /dev/zero". 2345 234619 May 2009 2347 2348* Try to guess if the window is UTF-8 by outputting a three-byte UTF-8 wide 2349 character and seeing how much the cursor moves. Currently tries to figure out 2350 if this works by some stupid checks on the terminal, these need to be 2351 rethought. Also might be better using a width 1 character rather than width 2. 2352* If LANG contains "UTF-8", assume the terminal supports UTF-8, on the grounds 2353 that anyone who configures it probably wants UTF-8. Not certain if this is 2354 a perfect idea but let's see if it causes any problems. 2355* New window option: monitor-content. Searches for a string in a window and if 2356 it matches, highlight the status line. 2357 235818 May 2009 2359 2360* main-horizontal layout and main-pane-height option to match vertical. 2361* New window option main-pane-width to set the width of the large left pane with 2362 main-vertical (was left-vertical) layout. 2363* Lots of layout cleanup. manual layout is now manual-vertical. 2364 236516 May 2009 2366 2367* select-layout command and a few default key bindings (M-0, M-1, M-2, M-9) to 2368 select layouts. 2369* Recreate server socket on SIGUSR1, per SF feature request 2792533. 2370 237114 May 2009 2372 2373* Keys in status line (p in vi mode, M-y in emacs) to paste the first line 2374 of the upper paste buffer. Suggested by Dan Colish. 2375* clear-history command to clear a pane's history. 2376* Don't force wrapping with \n when asked, let the cursor code figure it out. 2377 Should fix terminals which use this to detect line breaks. 2378* Major cleanup and restructuring of build infrastructure. Still separate files 2379 for GNU and BSD make, but they are now hugely simplified at the expense of 2380 adding a configure script which must be run before make. Now build and 2381 install with: 2382 2383 $ ./configure && make && sudo make install 2384 238504 May 2009 2386 2387* Use ACS line drawing characters for pane separator lines. 2388 238930 April 2009 2390 2391* Support command sequences without a space before the semicolon, for example 2392 "neww; neww" now works as well as "neww ; neww". "neww;neww" is still an 2393 error. 2394* previous-layout command. 2395* Display the layout name in window lists. 2396* Merge resize-pane-up and resize-pane-down into resize-pane with -U and -D 2397 flags. 2398 239929 April 2009 2400 2401* Get rid of compat/vis.* - only one function was used which is easily 2402 replaced,and less compat code == good. 2403 240427 April 2009 2405 2406* Avoid using the prompt history when the server is locked, and prevent any 2407 input entered from being added to the client's prompt history. 2408* New command, confirm-before (alias confirm), which asks for confirmation 2409 before executing a command. Bound "&" and "x" by default to confirm-before 2410 "kill-window" and confirm-before "kill-pane", respectively. 2411 241223 April 2009 2413 2414* Support NEL, yet another way of making newline. Fixes the output from some 2415 Gentoo packaging thing. Reported by someone on SF then logs that allowed a 2416 fix sent by tcunha. 2417* Use the xenl terminfo flag to detect early-wrap terminals like the FreeBSD 2418 console. Many thanks for a very informative email from Christian Weisgerber. 2419 242021 April 2009 2421 2422* tmux 0.8 released. 2423 242417 April 2009 2425 2426* Remove the right number of characters from the buffer when escape then 2427 a cursor key (or other key prefixed by \033) is pressed. Reported by 2428 Stuart Henderson. 2429 243003 April 2009 2431 2432* rotate-window command. -U flag (default) for up, -D flag for down. 2433 243402 April 2009 2435 2436* Change scroll/pane redraws to only redraw the single pane affected rather 2437 than the entire window. 2438* If redrawing the region would mean redrawing > half the pane, just schedule 2439 to redraw the entire window. Also add a flag to skip updating the window any 2440 further if it is scheduled to be redrawn. This has the effect of batching 2441 multiple redraws together. 2442 244301 April 2009 2444 2445* Basic horizontal splitting and layout management. Still some redraw and other 2446 issues - particularly, don't mix with manual pane resizing, be careful when 2447 viewing from multiple clients and don't expect shell windows to redraw very 2448 well after the layout is changed; generally cycling the layout a few times 2449 will fix most problems. Getting this in for testing while I think about how 2450 to deal with manual mode. 2451 2452 Split window as normal and cycle the layouts with C-b space. Some of the 2453 layouts will work better when swap-pane comes along. 2454 245531 March 2009 2456 2457* AIX port, thanks to cmihai for access to a box. Only tested on 6.1 with xlc 2458 10.1 (make sure CC is set). Needs GNU make and probably ncurses (didn't try 2459 plain curses). Also won't build with DEBUG, so comment the FDEBUG=1 line in 2460 GNUmakefile. 2461* Draw a vertical line on the right when the window size is less than the 2462 terminal size. This is partly to shake out any horizontal limit bugs on the 2463 way to horizontal splitting/pane tiling. Currently a bit slow since it has to 2464 do a lot of redrawing but hopefully that will improve as I get some better 2465 ideas for how to do it. 2466* Fix remaining problems with copy and paste and UTF-8. 2467 246828 March 2009 2469 2470* Better UTF-8 support, including combined characters. Unicode data is now 2471 stored as UTF-8 in a separate array, the code does a lookup into this every 2472 time it gets to a UTF-8 cell. Zero width characters are just appended onto 2473 the UTF-8 data for the previous cell. This also means that almost no bytes 2474 extra are wasted non-Unicode data (yay). 2475 2476 Still some oddities, such as copy mode skips over wide characters in a 2477 strange way, and the code could do with some tidying. 2478* Key repeating is now a property of the key binding not of the command. 2479 Repeat is turned on when the key is bound with the -r flag to bind-key. 2480 next/previous-window no longer repeat by default as it turned out to annoy 2481 me. 2482 248327 March 2009 2484 2485* Clear using ED when redrawing the screen. I foolishly assumed using spaces 2486 would be equivalent and terminals would pick up on this, but apparently not. 2487 This fixes copy and paste in xterm/rxvt. 2488* Sockets in /tmp are now created in a subdirectory named, tmux-UID, eg 2489 tmux-1000. The default socket is thus /tmp/tmux-UID/default. To start a 2490 separate server, the new -L command line option should be used: this creates 2491 a socket in the same directory with a different name ("-L main" will create 2492 socket called "main"). -S should only be used to place the socket outside 2493 /tmp. This makes sockets a little more secure and a bit more convenient to 2494 use multiple servers. 2495 249621 March 2009 2497 2498* New session flag "set-remain-on-exit" to set remain-on-exit flag for new 2499 windows created in that session (like "remain-by-default" used to do). Not 2500 perfectly happy about this, but until I can think of a good way to introduce 2501 it generically (maybe a set of options in the session) this will do. Fixes 2502 SF request 2527847. 2503 250407 March 2009 2505 2506* Support for 88 colour terminals. 2507* break-pane command to create a new window using an existing pane. 2508 250902 March 2009 2510 2511* Make escape key timer work properly so escape+key can be used without 2512 lightning fast key presses. 2513 251413 February 2009 2515 2516* Redo mode keys slightly more cleanly and apply them to command prompt 2517 editing. vi or emacs mode is controlled by the session option status-keys. 2518 251912 February 2009 2520 2521* Looking up argv[0] is expensive, so just use p_comm for the window name which 2522 is good enough. Also increase name update time to 500 ms. 2523 252411 February 2009 2525 2526* Only use ri when actually at the top of the screen; just move the cursor up 2527 otherwise. 2528* FreeBSD's console wraps lines at $COLUMNS - 1 rather than $COLUMNS (the 2529 cursor can never be beyond $COLUMNS - 1) and does not appear to support 2530 changing this behaviour, or any of the obvious possibilities (turning off 2531 right margin wrapping, insert mode). This is irritating, most notably because 2532 it impossible to write to the very bottom-right of the screen without 2533 scrolling. To work around this, if built on FreeBSD and run with a "cons" 2534 $TERM, the bottom-right cell on the screen is omitted. 2535* Emulate scroll regions (slowly) to support the few terminals which don't have 2536 it (some of which don't really have any excuse). 2537 253810 February 2009 2539 2540* No longer redraw the status line every status-interval unless it has actually 2541 changed. 2542 254308 February 2009 2544 2545* Don't treat empty arguments ("") differently when parsing configuration 2546 file/command prompt rather than command line. 2547* tmux 0.7 released. 2548 254903 February 2009 2550 2551* New command, copy-buffer (alias copyb), to copy a session paste buffer to 2552 another session. 2553 255401 February 2009 2555 2556* The character pair #(command) may now contain (escaped) right parenthesis. 2557 255830 January 2009 2559 2560* . now bound to "command-prompt 'move-window %%'" by default, from joshe. 2561 256229 January 2009 2563 2564* Window options to set status line fg, bg and attributes for a single 2565 window. Options are: window-status-fg, window-status-bg, 2566 window-status-attr. Set to "default" to use the session status colours. 2567 2568 This allows quite neat things like: 2569 2570 $ cat ~/bin/xssh 2571 #!/bin/sh 2572 2573 if [ ! -z "$TMUX" ]; then 2574 case "$1" in 2575 natalya) 2576 tmux setw window-status-fg red >/dev/null 2577 ;; 2578 natasha) 2579 tmux setw window-status-fg yellow >/dev/null 2580 ;; 2581 esac 2582 fi 2583 ssh "$@" 2584 [ ! -z "$TMUX" ] && tmux setw -u window-status-fg >/dev/null 2585 $ alias ssh="~/bin/xssh" 2586 2587* Support #(command) in status-left, and status-right, which is displayed as 2588 the first line of command's output (e.g. set -g status-right 2589 "#(whoami)@#(hostname -s)"). Commands with )s aren't supported. 2590 259128 January 2009 2592 2593* Support mouse in copy mode to move cursor. Can't do anything else at the 2594 moment until other mouse modes are handled. 2595* Better support for at least the most common variant of mouse input: parse it 2596 and adjust for different panes. Also support mouse in window/session choice 2597 mode. 2598 259927 January 2009 2600 2601* Bring back the fancy window titles with session/window names: it is easy to 2602 work around problems with elinks (see FAQ). 2603* -u flag to scroll-mode and copy-mode to start scrolled one page 2604 up. scroll-mode -u is bound to prefix,page-up (ppage) by default. 2605* Allow status, mode and message attributes to be changed by three new options: 2606 status-attr, mode-attr, message-attr. A comma-separated list is accepted 2607 containing: bright, dim, underscore, blink, reverse, hidden, italics, for 2608 example: 2609 2610 set -g status-attr bright,blink 2611 2612 From Josh Elsasser, thanks! 2613 261426 January 2009 2615 2616* Be more clever about picking the right process to create the window name. 2617* Don't balls up the terminal on UTF-8 combined characters. Don't support them 2618 properly either - they are just discarded for the moment. 2619 262025 January 2009 2621 2622* load-buffer command 2623 262423 January 2009 2625 2626* Use reverse colours rather than swapping fg and bg for message, mode and 2627 status line. This makes these usable on black and white terminals. 2628* Better error messages when creating a session or window fails. 2629* Oops. Return non-zero on error. Reported by Will Maier. 2630 263121 January 2009 2632 2633* Handle SIGTERM (and kill-server which uses it), a bit more neatly - tidy 2634 up properly and print a nicer message. Same effect though :-). 2635* new-window now supports -k to kill target window if it exists. 2636* Bring back split-window -p and -l options to specify the height a percentage 2637 or as a number of lines. 2638* Make window and session choice modes allow you to choose items in vi keys 2639 mode (doh!). As a side-effect, this makes enter copy selection (as well 2640 as C-w/M-w) when using emacs keys in copy mode. Reported by merdely. 2641 264220 January 2009 2643 2644* Darwin support for automatic-rename from joshe; Darwin doesn't seem to have 2645 a sane method of getting argv[0] and searching for the precise insane way 2646 is too frustrating, so this just uses the executable name. 2647* Try to change the window title to match the command running it in. This is 2648 done by reading argv[0] from the process group leader of the group that owns 2649 the tty (tcgetpgrp()). This can't be done portably so some OS-dependent code 2650 is introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment. 2651 2652 A new window flag, automatic-rename, is available: if this is set to off, the 2653 window name is not changed. Specifying a name with the new-window, 2654 new-session or rename-window commands will automatically set this flag to off 2655 for the window in question. To disable it entirely set the option to off 2656 globally (setw -g automatic-rename off). 2657 265819 January 2009 2659 2660* Fix various stupid issues when the status line is turned off. Grr. 2661* Use reverse attributes for clock and cursor, otherwise they do not 2662 appear on black and white terminals. 2663* An error in a command sequence now stops execution of that sequence. 2664 Internally, each command code now passes a return code back rather than 2665 talking to the calling client (if any) directly. 2666* attach-session now tries to start the server if it isn't already started - if 2667 no sessions are created in .tmux.conf this will cause an error. 2668* Clean up starting server by making initial client get a special socketpair. 2669 267018 January 2009 2671 2672* Unbreak UTF-8. 2673* -a flag to next-window and previous-window to select the next or previous 2674 window with activity or bell. Bound to M-n and M-p. 2675* find-window command to search window names, titles and visible content (but 2676 not history) for a string. If only one is found, the window is selected 2677 otherwise a choice list is shown. This (as with the other choice commands) 2678 only works from a key. Bound to "f" by default. 2679* Cleaned up command printing code, also enclose arguments with spaces in "s. 2680* Added command sequences. These are entered by separating each argument by a ; 2681 argument (spaces on both sides), for example: 2682 2683 lsk ; lsc 2684 2685 To use a literal ; as the argument prefix it with \, for example: 2686 2687 bind x lsk \; lsc 2688 2689 Commands are executed from left to right. Also note that command sequences do 2690 not support repeat-time repetition unless all commands making up the sequence 2691 support it. 2692* suspend-client command to suspend a client. Don't try to background it 2693 though... 2694* Mark attached sessions in sessions lists. Suggested by Simon Kuhnle. 2695 269617 January 2009 2697 2698* tmux 0.6 released. 2699 270015 January 2009 2701 2702* Support #H for hostname and #S for session name in status-left/right. 2703* Two new commands, choose-window and choose-session which work only when bound 2704 to a key and allow the window or session to be selected from a list. These 2705 are now bound to "w" and "s" instead of the list commands. 2706 270714 January 2009 2708 2709* Rework the prefix-time stuff. The option is now called repeat-time and 2710 defaults to 500 ms. It only applies to a small subset of commands, currently: 2711 up-pane, down-pane, next-window, previous-window, resize-pane-up, 2712 resize-pane-down. These are the commands for which it is obviously useful, 2713 having it for everything else was just bloody annoying. 2714* The alt-up and alt-down keys now resize a pane by five lines at a time. 2715* switch-pane is now select-pane and requires -p to select a pane. The 2716 "o" key binding is changed to down-pane. 2717* up-pane and down-pane commands, bound to arrow up and down by default. 2718* Multiple vertical window splitting. Minimum pane size is four lines, an 2719 (unhelpful) error will be shown if attempting to split a window with less 2720 that eight lines. If the window is resized, as many panes are shown as can 2721 fit without reducing them below four lines. There is (currently!) not a way 2722 to show a hidden pane without making the window larger. 2723 2724 Note the -p and -l options to split-window are now gone, these may reappear 2725 once I think them through again. 2726* Server locking on inactivity (lock-after-time) is now disabled by default. 2727 272813 January 2009 2729 2730* kill-pane command. 2731 273212 January 2009 2733 2734* command-prompt now accepts a single argument, a template string. Any 2735 occurrences of %% in this string are replaced by whatever is entered at the 2736 prompt and the result is executed as a command. This allows things like (now 2737 bound by default): 2738 2739 bind , command-prompt "rename-window %%" 2740 2741 Or my favourite: 2742 2743 bind x command-prompt "split-window 'man %%'" 2744 2745* Option to set prefix time, allowing multiple commands to be entered without 2746 pressing the prefix key again, so long as they each typed within this time of 2747 each other. 2748* Yet more hacks for key handling. Think it is just about working now. 2749* Two commands, resize-pane-up and resize-pane-down to resize a pane. 2750* Make the window pane code handle panes of different sizes, and add a -l 2751 and -p arguments to split-window to specify the new window size in lines 2752 or as a percentage. 2753 275411 January 2009 2755 2756* Vertical window splitting. Currently can only split a window into two panes. 2757 New split-window command splits (bound to ") and switch-pane command (bound to 2758 o) switches between panes. 2759 2760 close-pane, swap-pane commands are to follow. Also to come are pane resizing, 2761 >2 panes, the ability to break a pane out to a full window and vice versa and 2762 possibly horizontal splitting. 2763 2764 Panes are subelements of windows rather than being windows in their own 2765 right. I tried to make them windows (so the splitting was at the session or 2766 client level) but this rapidly became very complex and invasive. So in the 2767 interests of having something working, I just made it so each window can have 2768 two child processes instead of one (and it still took me 12 hours straight 2769 coding). Now the concept is proven and much of the support code is there, 2770 this may change in future if more flexibility is needed. 2771* save-buffer command, from Tiago Cunha. 2772 277310 January 2009 2774 2775* New option, lock-after-time. If there is no activity in the period specified 2776 by this option (in seconds), tmux will lock the server. Default is 1800 (30 2777 minutes), set to 0 to disable. 2778* Server locking. Two new commands: set-password to set a password (a 2779 preencrypted password may be specified with -c); and lock-server to lock the 2780 server until the password is entered. Also an additional command line flag, 2781 -U, to unlock from the shell. The default password is blank (any password 2782 accepted). If specifying an encrypted password from encrypt(1) in .tmux.conf 2783 with -c, don't forget to enclose it in single-quotes (') to prevent shell 2784 variable expansion. 2785* If a window is created from the command line, tmux will now use the same 2786 current working directory for the new process. A new default-path option to 2787 sets the working directory for processes created from keys or interactively 2788 from the prompt. 2789* New mode to display a large clock. Entered with clock-mode command (bound to 2790 C-b t by default); two window options: clock-mode-colour and clock-mode-style 2791 (12 or 24). This will probably be used as the basis for window locking. 2792* New command, server-info, to show some server information and terminal 2793 details. 2794 279509 January 2009 2796 2797* Stop using ncurses variables and instead build a table of the codes we want 2798 into an array for each terminal type. This makes the code a little more 2799 untidy in places but gets rid of the awful global variables and calling 2800 setterm all the time, and shoves all the ncurses-dependent mess into a single 2801 file, tty-term.c. It also allows overriding single terminal codes, this is 2802 used to fix rxvt on some platforms (where it is missing dch) and in future 2803 may allow user customisation a la vim. 2804* Update key handling code. Simplify, support ctrl properly and add a new 2805 window option (xterm-keys) to output xterm key codes including ctrl and, 2806 if available, alt and shift. 2807 280808 January 2009 2809 2810* If built without DEBUG (the release versions), don't cause a fatal error if 2811 the grid functions notice an input error, just log and ignore the 2812 request. This might mean me getting shouted at less often when bugs kill 2813 long-running sessions, at least in release versions. 2814* Hopefully fix cursor out-of-bounds checking when writing to grid. When I 2815 wrote the code I must have forgotten that the cursor can be one cell off the 2816 right of the screen (yes, I know), so there were number of out-of-bounds/ 2817 overflow problems. 2818 281907 January 2009 2820 2821* New flag to set and setw, -u, to unset an option (allowing it to inherit from) 2822 the global options again. 2823* Added more info messages for options changes. 2824* A bit of tidying and reorganisation of options code. 2825 282606 January 2009 2827 2828* Don't crash when backspacing if cursor is off the right of the screen, 2829 reported by David Chisnall. 2830* Complete words at any point inside command in prompt, also use option name 2831 as well as command names. 2832* Per-client prompt history of up to 100 items. 2833* Use a splay tree for key bindings instead of an array. As a side-effect this 2834 sorts them when listed. 2835 283622 December 2008 2837 2838* Use the right keys for home and end. 2839 284020 December 2008 2841 2842* Add vim mode for tmux configuration file to examples/, from Tiago Cunha. 2843 284415 December 2008 2845 2846* New command, source-file (alias source), to load a configuration 2847 file. Written by Tiago Cunha, many thanks. 2848 284913 December 2008 2850 2851* Work around lack of dch. On Linux, the rxvt termcap doesn't have it (it is 2852 lying, but we can't really start disbelieving termcaps...). This is a bit 2853 horrible - I can see no way to do it without pretty much redrawing the whole 2854 line, but it works... 2855 285610 December 2008 2857 2858* glibc's getopt(3) is useless: it is not POSIX compliant without jumping 2859 through non-portable hoops, and the method of resetting it is unclear (the 2860 man page on my system says set optind to 1, but other sources say 0). So, 2861 import OpenBSD's getopt_long.c into compat/ for use on Linux and use the 2862 clearly documented optreset = optind = 1 method. This fixes some strange 2863 issues with command parsing (getting the syntax wrong would prevent any 2864 further commands being parsed). 2865 286606 December 2008 2867 2868* Bring set/setw/show/showw into line with other commands. This means that by 2869 default they now affect the current window (if any); the new -g flag must be 2870 passed to set the global options. This changes the behaviour of set/show and 2871 WILL BREAK CURRENT CONFIGURATIONS. 2872 2873 In summary, whether in the configuration file, the command prompt, or a key 2874 binding, use -g to set a global option, use -t to specify a particular window 2875 or session, or omit both to try and use the current window or session. 2876 2877 This makes set/show a bit of a pain but is the correct behaviour for 2878 setw/showw and is the same as every other command, so we can put up with a 2879 bit of pain for consistency. 2880* Redo window options. They now work in the same way to session options with a 2881 global options set. showw/setw commands now have similar syntax to show/set 2882 (including the ability to use abbreviations). 2883 2884 PLEASE NOTE this includes the following configuration-breaking changes: 2885 2886 - remain-by-default is now GONE, use "setw -g remain-on-exit" to apply the 2887 global window option instead; 2888 - mode-keys is now a window option rather than session - use "setw [-g] 2889 mode-keys" instead of set. 2890 2891 There are also some additions: 2892 2893 - message-fg and message-bg session options to control status line message 2894 colours; 2895 - mode-fg and mode-bg window options to set colours in window modes such as 2896 copy mode. 2897 2898 The options code still a mess and now there is twice as much of it :-(. 2899 290002 December 2008 2901 2902* Add support for including the window title in status-left or status-right 2903 strings by including the character pair "#T". This may be prefixed with 2904 a number to specify a maximum length, for example "#24T" to use at most 2905 24 characters of the title. 2906* Introduce two new options, status-left-length and status-right-length, 2907 control the maximum length of left and right components of the status bar. 2908* elinks (and possibly others) bypass the terminal and talk directly to X to 2909 restore the window title when exiting. tmux can't know about this particular 2910 bit of stupidity so the title ends up strange - the prefix isn't terribly 2911 important and elinks is quite useful so just get rid of it. 2912 291327 November 2008 2914 2915* Tweaks to support Dragonfly. 2916 291717 November 2008 2918 2919* tmux 0.5 released. 2920 292116 November 2008 2922 2923* New window option: "utf8"; this must be on (it is off by default) for UTF-8 2924 to be parsed. The global/session option "utf8-default" controls the setting 2925 for new windows. 2926 2927 This means that by default tmux does not handle UTF-8. To use UTF-8 by 2928 default it is necessary to a) "set utf8-default on" in .tmux.conf b) start 2929 tmux with -u on any terminal which support UTF-8. 2930 2931 It seems a bit unnecessary for this to be a per-window option but that is 2932 the easiest way to do it, and it can't do any harm... 2933* Enable default colours if op contains \033[39;49m, based on a report from 2934 fulvio ciriaco. 2935 293612 November 2008 2937 2938* Keep stack of last windows rather than just most recent; based on a diff from 2939 joshe. 2940 294104 November 2008 2942 2943* Don't try to redraw status line when showing a prompt or message; if it does, 2944 the status timer is never reset so it redraws on every loop. Spotted by 2945 joshe. 2946 294709 October 2008 2948 2949* Translate 256 colours into 16 if 256 is not available, same as screen does. 2950* Better support for OSC command (only to set window title now), and also 2951 support using APC for the same purpose (some Linux default shell profiles do 2952 this). 2953 295425 September 2008 2955 2956* Large internal rewrite to better support 256 colours and UTF-8. Screen data 2957 is now stored as single two-way array of structures rather than as multiple 2958 separate arrays. Also simplified a lot of code. 2959 2960 Only external changes are three new flags, -2, -d and -u, which force tmux to 2961 assume the terminal supports 256 colours, default colours (useful for 2962 xterm-256color which lacks the AX flag), or UTF-8 respectively. 2963 296410 September 2008 2965 2966* Split off colour conversion code from screen code. 2967 296809 September 2008 2969 2970* Initial UTF-8 support. A bit ugly and with a limit of 4096 UTF-8 2971 characters per window. 2972 297308 September 2008 2974 2975* 256 colour support. tmux attempts to autodetect the terminal by looking 2976 both at what ncurses reports (usually wrong for xterm) and checking if 2977 the TERM contains "256col". For xterm TERM=xterm-256color is needed (as 2978 well as a build that support 256 colours); this seems to work for rxvt 2979 as well. On non-256 colour terminals, high colours are translated to white 2980 foreground and black background. 2981 298228 August 2008 2983 2984* Support OS X/Darwin thanks to bsd-poll.c from OpenSSH. Also convert 2985 from clock_gettime(2) to gettimeofday(2) as OS X doesn't support the 2986 former; microsecond accuracy will have to be sufficient ;-). 2987 298807 August 2008 2989 2990* Lose some unused/useless wrapper functions. 2991 299225 July 2008 2993 2994* Shell variables may now be defined and used in configuration file. Define 2995 variables with: 2996 2997 VAR=1 2998 2999 And use with: 3000 3001 renamew ${VAR} 3002 renamew "x${VAR}x" 3003 3004 Also some other fixes to make, for example, "abc""abc" work similarly to 3005 the shell. 3006 300724 July 2008 3008 3009* Finally lose inconsistently-used SCREEN_DEF* defines. 3010* If cursor mode is on, switch the arrow keys from \033[A to \033OA. 3011* Support the numeric keypad in both application and numbers mode. This is 3012 different from screen which always keeps it in application mode. 3013 301419 July 2008 3015 3016* Unbreak "set status" - tmux thought it was ambiguous, reported by rivo nurges. 3017 301802 July 2008 3019 3020* Split vi and emacs mode keys into two tables and add an option (mode-keys) 3021 to select between them. Default is emacs, use, 3022 3023 tmux set mode-keys vi 3024 3025 to change to vi. 3026 3027 vi mode uses space to start selection, enter to copy selection and escape 3028 to clear selection. 3029 303001 July 2008 3031 3032* Protocol versioning. Clients which identify as a different version from the 3033 server will be rejected. 3034* tmux 0.4 released. 3035 303629 June 2008 3037 3038* Zombie windows. These are not closed when the child process dies. May be 3039 set for a window with the new "remain-on-exit" option; the default setting 3040 of this flag for new windows may be set with the "remain-by-default" session 3041 option. 3042 3043 A window may be restarted with the respawn-window command: 3044 3045 respawn-window [-k] [command] 3046 3047 If -k is given, any existing process running in the window is killed; 3048 if command is omitted, the same command as when the window was first 3049 created is used. 3050 305127 June 2008 3052 3053* Handle nonexistent session or client to -t properly. 3054 305525 June 2008 3056 3057* select-prompt command to allow a window to be selected at a prompt. Only 3058 windows in the current session may be selected. Bound to ' by default. 3059 Suggested by merdely. 3060* move-window command. Requested by merdely. 3061* Support binding alt keys (prefixed with M-). Change default to use 3062 C- for ctrl keys (^ is still accepted as an alternative). 3063* Slim down default key bindings: support lowercase only. 3064* Handle escaped keys properly (parse eg \033b into a single key code) and 3065 use this to change copy mode next/previous work to M-f and M-b to match 3066 emacs. 3067 306824 June 2008 3069 3070* Next word (C-n/w) and previous word (C-b/b) in copy mode. 3071 307223 June 2008 3073 3074* list-commands command (alias lscm). 3075* Split information about options into a table and use it to parse options 3076 on input (allowing abbreviations) and to print them with show-options 3077 (meaning that bell-action gets a proper string). This turned out a bit ugly 3078 though :-/. 3079 308022 June 2008 3081 3082* Do not translate black and white into default if the terminal supports 3083 default colours. This was nice to force programs which didn't use default 3084 colours to be properly transparent in rxvt/aterm windows with a background 3085 image, but it causes trouble if someone redefines the default foreground and 3086 background (to have black on white or something). 3087 308821 June 2008 3089 3090* Naive tab completion in the command prompt. This only completes command 3091 names if a) they are at the start of the text b) the cursor is at 3092 the end of the text c) the text contains no spaces. 3093* Only attempt to set the title where TERM looks like an xterm (contains 3094 "xterm", "rxvt" or is "screen"). I hate this but I don't see a better way: 3095 setting the title actually kills some other terminals pretty much dead. 3096* Strip padding out of terminfo(5) strings. Currently the padding is just 3097 ignored, this may need to be altered if there are any software terminals 3098 out there that actually need it. 3099 310020 June 2008 3101 3102* buffer-limit option to set maximum size of buffer stack. Default is 9. 3103* Initial buffer improvements. Each session has a stack of buffers and each 3104 buffer command takes a -b option to manipulate items on the stack. If -b 3105 is omitted, the top entry is used. The following commands are currently 3106 available: 3107 3108 set-buffer [-b index] [-t target-session] string 3109 paste-buffer [-d] [-b index] [-t target-window] 3110 delete-buffer [-b index] [-t target-session] 3111 show-buffers [-t target-session] 3112 show-buffer [-b index] [-t target-session] 3113 3114 -d to paste-buffer deletes the buffer after pasting it. 3115* New option, display-time, sets the time status line messages stay on screen 3116 (unless a key is pressed). Set in milliseconds, default is 750 (0.75 seconds). 3117 The timer is only checked every 100 ms or so. 3118 311919 June 2008 3120 3121* Use "status" consistently for status line option, and prefix for "prefix" key 3122 option. 3123* Allow commands to be entered at a prompt. This is triggered with the 3124 command-prompt command, bound to : by default. 3125* Show status messages properly, without blocking the server. 3126 312718 June 2008 3128 3129* New option, set-titles. On by default, this attempts to set the window title 3130 using the \e]2;...\007 xterm code. 3131 3132 Note that elinks requires the STY environment variable (used by screen) to be 3133 set before it will set the window title. So, if you want window titles set by 3134 elinks, set STY before running it (any value will do). I can't do this for all 3135 windows since setting it to an invalid value breaks screen. 3136* Show arrows at either end of status line when scrolled if more windows 3137 exist. Highlight the arrow if a hidden window has activity or bell. 3138* Scroll the status line to show the current window if necessary. Also handle 3139 windows smaller than needed better (show a blank status line instead of 3140 hanging or crashing). 3141 314217 June 2008 3143 3144* tmux 0.3 released. 3145 314616 June 2008 3147 3148* Add some information messages when window options are changed, suggested by 3149 Mike Erdely. Also add a -q command-line option to suppress them. 3150* show-window-options (showw) command. 3151 315215 June 2008 3153 3154* show-options (show) command to show one or all options. 3155 315614 June 2008 3157 3158* New window options: force-width and force-height. This will force a window 3159 to an arbitrary width and height (0 for the default unlimited). This is 3160 neat for emacs which doesn't have a sensible way to force hard wrapping at 80 3161 columns. Also, don't try to be clever and use clr_eol when redrawing the 3162 whole screen, it causes trouble since the redraw functions are used to draw 3163 the blank areas too. 3164* Clear the blank area below windows properly when they are smaller than client, 3165 also add an indicator line to show the vertical limit. 3166* Don't die on empty strings in config file, reported by Will Maier. 3167 316808 June 2008 3169 3170* Set socket mode +x if any sessions are attached and -x if not. 3171 317207 June 2008 3173 3174* Make status-interval actually changeable. 3175 317606 June 2008 3177 3178* New window option: aggressive-resize. Normally, windows are resized to the 3179 size of the smallest attached session to which they are linked. This means a 3180 window only changes size when sessions are detached or attached, or they are 3181 linked or unlinked from a session. This flag changes a window to be the size 3182 of the smallest attached session for which it is the current window - it is 3183 resized every time a session changes to it or away from it. This is nice for 3184 things that handle SIGWINCH well (like irssi) and bad for things like shells. 3185* The server now exits when no sessions remain. 3186* Fix bug with inserting characters with TERM=xterm-color. 3187 318805 June 2008 3189 3190* Completely reorganise command parsing. Much more common code in cmd-generic.c 3191 and a new way of specifying windows, clients or sessions. Now, most commands 3192 take a -t argument, which specifies a client, a session, or a window target. 3193 Clients and sessions are given alone (sessions are fnmatch(3)d and 3194 clients currently not), windows are give by (client|session):index. For 3195 example, if a user is in session "1" window 0 on /dev/ttypi, these should all 3196 be equivalent: 3197 3198 tmux renamew newname (current session and window) 3199 tmux renamew -t: newname (current session and window) 3200 tmux renamew -t:0 newname (current session, window 0) 3201 tmux renamew -t0 newname (current session, window 0) 3202 tmux renamew -t1:0 newname (session 1, window 0) 3203 tmux renamew -t1: newname (session 1's current window) 3204 tmux renamew -t/dev/ttypi newname (client /dev/ttypi's current 3205 session and window) 3206 tmux renamew -t/dev/ttypi: newname (client /dev/ttypi's current 3207 session and window) 3208 tmux renamew -t/dev/ttypi:0 newname (client /dev/ttypi's current 3209 session, window 0) 3210 3211 This does have some downsides, for example, having to use -t on selectw, 3212 3213 tmux selectw -t7 3214 3215 is annoying. But then using non-flagged arguments would mean renaming the 3216 current window would need to be something like: 3217 3218 tmux renamew : newname 3219 3220 It might be better not to try and be so consistent; comments to the usual 3221 address ;-). 3222* Infrastructure for printing arguments in list-keys output. Easy ones only for 3223 now. 3224 322504 June 2008 3226 3227* Add some vi(1) key bindings in copy mode, and support binding ^[, ^\, ^] 3228 ^^ and ^_. Both from/prompted by Will Maier. 3229* setw monitor-activity and set status without arguments now toggle the current 3230 value; suggested by merdely. 3231* New command set-window-option (alias setw) to set the single current window 3232 option: monitor-activity to determine whether window activity is shown in 3233 the status bar for that window (default off). 3234* Change so active/bell windows are inverted in status line. 3235* Activity monitoring - window with activity are marked in status line. No 3236 way to disable this/filter windows yet. 3237* Brought select-window command into line with everything else; it now uses 3238 -i for the window index. 3239* Strings to display on the left and right of the status bar may now be set 3240 with the status-left and status-right options. These are passed through 3241 strftime(3) before being displayed. The status bar is automatically updated 3242 at an interval set by the status-interval option. The default is to display 3243 nothing on the left and the date and time on the left; the default update 3244 interval is 15 seconds. 3245 324603 June 2008 3247 3248* Per session options. Setting options without specifying a session sets the 3249 global options as normal (global options are inherited by all sessions); 3250 passing -c or -s will set the option only for that session. 3251* Because a client has a session attached, any command needing a session can 3252 take a client and use its session. So, anything that used to accept -s now 3253 accepts -c as well. 3254* -s to specify session name now supports fnmatch(3) wildcards; if multiple 3255 sessions are found, or if no -s is specified, the most newly created is used. 3256* If no command is specified, assume new-session. As a byproduct, clean up 3257 command default values into separate init functions. 3258* kill-server command. 3259 326002 June 2008 3261 3262* New command, start-server (alias "start"), to start the tmux server and do 3263 nothing else. This is good if you have a configuration file which creates 3264 windows or sessions (like me): in that case, starting the server the first 3265 time tmux new is run is bad since it creates a new session and window (as 3266 it is supposed to - starting the server is a side-effect). 3267 3268 Instead, I have a little script which does the equivalent of: 3269 3270 tmux has -s0 2>/dev/null || tmux start 3271 tmux attach -d -s0 3272 3273 And I use it to start the server if necessary and attach to my primary 3274 session. 3275* Basic configuration file in ~/.tmux.conf or specified with -f. This is file 3276 contains a set of tmux commands that are run the first time the server is 3277 started. The configuration commands are executed before any others, so 3278 if you have a configuration file that contains: 3279 3280 new -d 3281 neww -s0 3282 3283 And you do the following without an existing server running: 3284 3285 tmux new 3286 3287 You will end up with two sessions, session 0 with two windows (created by 3288 the configuration file) and your client attached to session 1 with one 3289 window (created by the command-line command). I'm not completely happy with 3290 this, it seems a little non-obvious, but I haven't yet decided what to do 3291 about it. 3292 3293 There is no environment variable handling or other special stuff yet. 3294 3295 In the future, it might be nice to be able to have per-session configuration 3296 settings, probably by having conditionals in the file (so you could, for 3297 example, have commands to define a particular window layout that would only 3298 be invoked if you called tmux new -smysession and mysession did not already 3299 exist). 3300* BIG CHANGE: -s and -c to specify session name and client name are now passed 3301 after the command rather than before it. So, for example: 3302 3303 tmux -s0 neww 3304 3305 Becomes: 3306 3307 tmux neww -s0 3308 3309 This is to allow them to be used in the (forthcoming) configuration file 3310 THIS WILL BREAK ANY CURRENT SCRIPTS OR ALIASES USING -s OR -c. 3311 331201 June 2008 3313 3314* Bug fix: don't die if -k passed to link-window and the destination doesn't 3315 exist. 3316* New command, send-keys, will send a set of keys to a window. 3317 331831 May 2008 3319 3320* Fix so tmux doesn't hang if the initial window fails for some reason. This 3321 was highlighted by problems on Darwin, thanks to Elias Pipping for the report 3322 and access to a test account. (tmux still won't work on Darwin since its 3323 poll(2) is broken.) 3324 332502 January 2008 3326 3327* Don't attempt to reset the tty on exit if it has been closed externally. 3328 332906 December 2007 3330 3331* Restore checks for required termcap entries and add a few more obvious 3332 emulations. 3333* Another major reorganisation, this time of screen handling. A new set of 3334 functions, screen_write_*, are now used to write to a screen and a tty 3335 simultaneously. These are used by the input parser to update the base 3336 window screen and also by the different modes which now interpose their own 3337 screen. 3338 333930 November 2007 3340 3341* Support \ek...\e\ to set window name. 3342 334327 November 2007 3344 3345* Enable/disable mouse when asked, if terminal claims to support it. Mouse 3346 sequences are just passed through unaltered for the moment. 3347* Big internal reorganisation. Rather than leaving control of the tty solely in 3348 the client and piping all data through a socket to it, change so that the 3349 server opens the tty again and reads and writes to it directly. This avoids 3350 a lot of buffering and copying. Also reorganise the redrawing stuff so that 3351 everything goes through screen_draw_* - this makes the code simpler, but 3352 still needs broken up more, and all the ways of writing to screens should be 3353 more consistent. 3354 335526 November 2007 3356 3357* Rather than shifting up one line at a time once the history is full, 3358 shift by 10% of the history each time. This is faster. 3359* Add ^A and ^E to copy mode to move to start-of-line/end-of-line. 3360 336124 November 2007 3362 3363* Support for alt charset mode (VT100 graphics characters). 3364 336523 November 2007 3366 3367* Mostly complete copy & paste. Copy mode entered with C-b [ (copy-mode 3368 command). In copy mode, arrow keys/page up/page down/hjkl/C-u/C-f navigate, 3369 space or C-space starts selection, and enter or C-w copies and (important!) 3370 exits copy mode. C-b ] (paste-buffer) pastes into current window. No 3371 extra utility keys (bol/eol/clear selection/etc), only one single buffer, 3372 and no buffer manipulation commands (clear/view/etc) yet. The code is also 3373 fugly :-(. 3374* history-limit option to set maximum history. Does not apply retroactively to 3375 existing windows! Lines take up a variable amount of space, but a reasonable 3376 guess for an 80-column terminal is 250 KB per 1000 lines (of history used, 3377 an empty history takes no space). 3378 337921 November 2007 3380 3381* Create every line as zero length and only expand it as data is written, 3382 rather than creating at full size immediately. 3383* Make command output (eg list-keys) go to a scrollable window similar to 3384 scroll mode. 3385* Redo screen redrawing so it is a) readable b) split into utility functions 3386 that can be used outside screen.c. Use these to make scroll mode only 3387 redraw what it has to which gets rid of irritating flickering status box and 3388 makes it much faster. 3389* Full line width memory and horizontal scrolling in history. 3390* Initial support for scroll history. = to enter scrolling mode, and then 3391 vi keys or up/down/pgup/pgdown to navigate. Q to exit. No horizontal history 3392 yet (need per-line sizes) and a few kinks to be worked out (resizing while in 3393 history mode will probably cause trouble). 3394 339520 November 2007 3396 3397* Fix format string error with "must specify a client" message. Also 3398 sprinkle some printflike tags. 3399* tmux 0.1 released. 3400 340117 November 2007 3402 3403* (nicm) Add -k option to link-window to kill target window if it exists. 3404 340516 November 2007 3406 3407* (nicm) Split in-client display into two columns. This is a hack but not a lot 3408 more so than that bit is already and it helps with lots of keys. 3409* (nicm) switch-client command to switch client between different sessions. This 3410 is pretty cool: 3411 3412 $ tmux bind q switch 0 3413 $ tmux bind w switch 1 3414 3415 Then you can switch between sessions 0 and 1 with a key :-). 3416* (nicm) Accept "-c client-tty" on command line to allow client manipulation 3417 commands, and change detach-/refresh-session to detach-/refresh-client (this 3418 loses the -a behaviour, but at some point -session versions may return, and 3419 -c will allow fnmatch(3)). 3420* (nicm) List available commands on ambiguous command. 3421 342212 November 2007 3423 3424* (nicm) If the terminal supports default colours (AX present), force black 3425 background and white foreground to default. This is useful on transparent 3426 *terms for programs which don't do it themselves (like most(1)). 3427* (nicm) Fill in the rest of the man page. 3428* (nicm) kill-session command. 3429 343009 November 2007 3431 3432* (nicm) C-space is now "^ " not "^@". 3433* (nicm) Support tab (\011). 3434* (nicm) Initial man page outline. 3435* (nicm) -V to show version. 3436* (nicm) rename-session command. 3437 343808 November 2007 3439 3440* (nicm) Check for required terminal capabilities on start. 3441 344231 October 2007 3443 3444* (nicm) Linux port. 3445 344630 October 2007 3447 3448* (nicm) swap-window command. Same as link-window but swaps windows. 3449 345026 October 2007 3451 3452* (nicm) Saving scroll region on \e7 causes problems with ncmpc so I guess 3453 it is not required. 3454* (nicm) unlink-window command. 3455* (nicm) link-window command to link an existing window into another session 3456 (or another index in the same session). Syntax: 3457 3458 tmux -s dstname link-window [-i dstidx] srcname srcidx 3459 3460* (nicm) Redo window data structures. The global array remains, but each per- 3461 session list is now a RB tree of winlink structures. This disassociates the 3462 window index from the array size (allowing arbitrary indexes) which still 3463 allowing windows to have multiple indexes. 3464 346525 October 2007 3466 3467* (nicm) has-session command: checks if session exists. 3468 346924 October 2007 3470 3471* (nicm) Support for \e6n to request cursor position. resize(1) now works. 3472* (nicm) Support for \e7, \e8 save/restore cursor and attribute sequences. 3473 Currently don't save mode (probably should). Also change some cases where 3474 out-of-bound values are ignored to limit them to within range (there are 3475 others than need to be checked too). 3476 347723 October 2007 3478 3479* (nicm) Lift limit on session name passed with -s. 3480* (nicm) Show size in session/window lists. 3481* (nicm) Pass tty up to server when client identifies and add a list-clients 3482 command to list connected clients. 3483 348420 October 2007 3485 3486* (nicm) Add default-command option and change default to be $SHELL rather than 3487 $SHELL -l. Also try to read shell from passwd db if $SHELL isn't present. 3488 348919 October 2007 3490 3491* (nicm) -n on new-session is now -s, and -n is now the initial window name. 3492 This was documented but not implemented :-/. 3493* (nicm) kill-window command, bound to & by default (because it should be hard 3494 to hit accidentally). 3495* (nicm) bell-style option with three choices: "none" completely ignore bell; 3496 "any" pass through a bell in any window to current; "current" ignore bells 3497 except in current window. This applies only to the bell terminal signal, 3498 the status bar always reflects any bells. 3499* (nicm) Refresh session command. 3500 350112 October 2007 3502 3503* (nicm) Add a warning if $TMUX exists on new/attach. 3504* (nicm) send-prefix command. Bound to C-b by default. 3505* (nicm) set status, status-fg, status-bg commands. fg and bg are as a number 3506 from 0 to 8 or a string ("red", "blue", etc). status may be 1/0, on/off, 3507 yes/no. 3508* (nicm) Make status line mark window in yellow on bell. 3509 351004 October 2007 3511 3512* (nicm) -d option to attach to detach all other clients on the same session. 3513* (nicm) Partial resizing support. Still buggy. A C-b S and back sometimes fixes 3514 it when it goes wonky. 3515* (mxey) Added my tmux start script as an example (examples/start-tmux.sh). 3516* (mxey) New sessions can now be given a command for their first window. 3517* (mxey) Fixed usage statement for new-window. 3518* (nicm) attach-session (can't believe I forgot it until now!) and list-windows 3519 commands. 3520* (nicm) rename-window and select-window commands. 3521* (nicm) set-option command (alias set): "tmux set-option prefix ^A". 3522* (nicm) Key binding and unbinding is back. 3523 352403 October 2007 3525 3526* (nicm) {new,next,last,previous}-window. 3527* (nicm) Rewrite command handling so commands are much more generic and the 3528 same commands are used for command line and keys (although most will probably 3529 need to check how they are called). Currently incomplete (only new/detach/ls 3530 implemented). Change: -s is now passed before command again! 3531* (nicm) String number arguments. So you can do: tmux bind ^Q create "blah". 3532* (nicm) Key binding. tmux bind key command [argument] and tmux unbind key. 3533 Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A. 3534 Possible commands are in cmd.c (look at cmd_bind_table). 3535* (nicm) Move command parsing into the client. Also rename some messages and 3536 tidy up a few bits. Lots more tidying up needed :-/. 3537 353802 October 2007 3539 3540* (nicm) Redraw client status lines on rename. 3541* (nicm) Error on ambiguous command. 3542 354301 October 2007 3544 3545* (nicm) Restore window title handling. 3546* (nicm) Simple uncustomisable status line with window list. 3547 354830 September 2007 3549 3550* (nicm) Window info command for debugging, C-b I. 3551 355229 September 2007 3553 3554* (nicm) Deleting/inserting lines should follow scrolling region. Fix. 3555* (nicm) Allow creation of detached sessions: "tmux new-session -d". 3556* (nicm) Permit error messages to be passed back for transient clients like 3557 rename. Also make rename -i work. 3558* (nicm) Pass through bell in any window to current. 3559 356028 September 2007 3561 3562* (nicm) Major rewrite of input parser: 3563 - Lose the old weirdness in favour of a state machine. 3564 - Merge in parsing from screen.c. 3565 - Split key parsing off into a separate file. 3566 This is step one towards hopefully allowing a status line. It requires 3567 that we output data as if the terminal had one line less than it really does - 3568 a serious problem when it comes to things like scrolling. This change 3569 consolidates all the range checking and limiting together which should make 3570 it easier. 3571* (mxey) Added window renaming, like "tmux rename [-s session] [-i index] name" 3572 357327 September 2007 3574 3575* Split "tmux list" into "tmux list-sessions" (ls) and "list-windows" (lsw). 3576* New command session selection: 3577 - if name is specified, look for it and use it if it exists, otherwise 3578 error 3579 - if no name specified, try the current session from $TMUX 3580 - if $TMUX doesn't exist, and there is only one session, use it, 3581 otherwise error 3582 358326 September 2007 3584 3585* Add command aliases, so "ls" is an alias for "list". 3586* Rename some commands and alter syntax to take options after a la CVS. Also 3587 change some flags. So: 3588 3589 tmux -s/socket -nabc new 3590 3591 Becomes: 3592 3593 tmux -S/socket new -sabc 3594 3595* Major tidy and split of client/server code. 3596 359722 September 2007 3598 3599* Window list command (C-b W). Started by Maximilian Gass, finished by me. 3600 360120 September 2007 3602 3603* Specify meta via environment variable (META). 3604* Record last window and ^L key to switch to it. Largely from Maximilian Gass. 3605* Reset ignored signals in child after forkpty, makes ^C work. 3606* Wrap on next/previous. From Maximilian Gass. 3607 360819 September 2007 3609 3610* Don't renumber windows on close. 3611 361228 August 2007 3613 3614* Scrolling region (\e[r) support. 3615 361627 August 2007 3617 3618* Change screen.c to work more logically and hopefully fix heap corruption. 3619 362009 July 2007 3621 3622* Initial import to CVS. Basic functions are working, albeit with a couple of 3623 showstopper memory bugs and many missing features. Detaching, reattaching, 3624 creating new sessions, listing sessions work acceptably for using with shells. 3625 Simple curses programs (top, systat, tetris) and more complicated ones (mutt, 3626 emacs) that don't require scrolling regions (ESC[r) mostly work fine 3627 (including mutt, emacs). No status bar yet and no key remapping or other 3628 customisation. 3629
