| NOTES |
| ===== |
| |
| This file describes rough notes regarding ideas for potential future tmux |
| development. It's not necessarily guaranteed that items in this TODO file |
| will ever get implemented. |
| |
| It is asked therefore, that anyone thinking of undertaking a task in this |
| TODO file, email tmux-users@lists.sf.net to discuss the feature. |
| |
| In terms of submitting patches, see the PATCHES file. |
| |
| Thie file is split up between tmux user interface (UI) issues, and terminal |
| compatibility issues. |
| |
| TMUX UI ISSUES |
| ============== |
| |
| - implicitly add exec to the commands for new windows (switch to disable it)? |
| - bring back detach-session to detach all clients on a session? |
| - allow fnmatch for -c, so that you can, eg, detach all clients |
| - garbage collect window history (100 lines at a time?) if it hasn't been used |
| in $x time |
| - flags to centre screen in window |
| - activity/bell should be per-window not per-link? what if it is cur win in |
| session not being watched? |
| - should be able to move to a hidden pane and it would be moved into view. pane |
| number in status line/top-right would be cool for this |
| - support other mouse modes (highlight etc) and use it in copy mode |
| - set-remain-on-exit is a bit of a hack, some way to do it generically? |
| - would be nice to be able to use "--" to mark start of command w/ neww etc |
| to avoid quoting |
| - make command sequences more usable: don't require space after ;, handle |
| errors better |
| - attach should have a flag to create session if it doesn't exist |
| - choice and more mode would be better per client than per window? |
| - hooks to which commands may be attached, for example: tmux add-hook |
| "new-session" if-shell "[ -e $HOME/.tmux-session.conf ]" source-file |
| $HOME/.tmux-session.conf |
| - way to set socket path from config file |
| - what about utmp etc? can tmux update it like screen? setgid? |
| - warts on current naming: |
| - display-time but message-fg/bg/attr |
| - list-* vs show-* |
| - server-info |
| - up-pane/down-pane/swap-pane -U/swap-pane -D vs next-*/previous-* |
| - split-window -> split-pane?? |
| - a way for force-width/height to apply to only one pane (how?) |
| - command to list what is actually running in each window with command line, |
| pid (need some adaption of the osdep code) |
| - some way to force a screen to use the entire terminal even if it is forced |
| to be smaller by other clients. pan smaller terminal? (like screen F) |
| -- idea of a "view" onto a window, need base x/y offsets for redraw |
| - handle resize better in copy mode |
| - way to copy stuff that is off screen due to resize |
| - commands should be able to succeed or fail and have || or && for command |
| lists |
| - some way to KEEP a command running continually and just use its LAST line of |
| output |
| - UTF-8 to a non-UTF-8 terminal should not be able to balls up |
| the terminal - www/ruby-addressable; make regress |
| - support esc-esc to quit in modes |
| - fix ctrl+F1-F4 output. to what? |
| - better utf8 support: window names, prompt input, message display |
| - session history for client and last-session command |
| - option to change status line colour when current window is in a mode? |
| - option to move copy mode indicator into status line |
| - list-buffer/show-buffer should display UTF-8 |
| - selection behaviour closer to vi in vi mode |
| - live update: server started with -U connects to server, requests sessions and |
| windows, receives fds |
| - sort out inheriting config from shell on new sessions/windows: |
| should pick up default-path/termios/etc from client if possible, |
| else leave empty/default |
| - link panes into multiple windows |
| - bells should be passed between sessions with visual-bell etc |
| sequence until its shell exits, to allow them to be used from the config file |
| - better session sharing: create-socket command to create socket somewhere (-r |
| flag for readonly) |
| - multiline status line (no?) |
| - flag for absolute pane size to resize-pane |
| - sanity check input to socket |
| - support title stack, both internally and externally |

| - command to show status line information briefly when it is off |
| - some way to pad # stuff with spaces, #!2T maybe |
| - a binding to "scroll down and exit at bottom" copy mode |
| - some way to pass keystrokes in copy mode through to underlying window |
| - last window update time and # replacement for it for display-message |
| - find-window across sessions - other ways to make session handling easier? |
| - ' and " should be parsed the same (eg "\e" vs '\e') in config and command |
| prompt? |
| - command to toggle selection not to move it in copy-mode |
| - audit of escape sequence support vs xterm |
| - support binding keys to mouse (mouse-select-pane -> mouse-keys or something, |
| mouse click == select-pane -t %%, mouse scroll up == copy-mode) |
| - something for -t "last window in session" so a session can be used as a stack |
| - synchronous commands - client sends cmd and blocks, neww/splitw saves client |
| ptr then when program inside died, sends MSG_SOMETHING with wait status to |
| client |
| - bind commands to key sequences? -- make it so ALL keys go through a table, |
| first an implicit table in which C-b is the only default binding to a |
| command that says "next key from $othertable" and so on. means -n can |
| go away as well |
| - monitor, bell etc should monitor /all/ panes in the window not just one |
| - a history of commands that can be reversed (reverse member of each command, |
| and a buffer) info() when changing to same window |
| - way to add dest for break-pane; maybe some easier way to unbreak-pane |
| - case insensitive searching |
| - configurable borders and empty space filler for when panes < window? |
| - mouse-select-pane will screw up with !MODE_MOUSE_STANDARD (it sets the |
| flag on w/o checking the others before calling tty_update_mode) |
| - multiple keys could be done with tables, ie have prefixes go and instead |
| bind -n ^A prefix-table "default" |
| where prefix-table sets command lookup table and sets prefix flag, then next |
| key is looked up in that table |
| - pass shell commands as argv rather than strings, allow them to be specified |
| in commands without quotes |
| - numeric prefix in copy mode should be paste buffer for C-w |
| - named buffers and allow gaps in the stack |
| - get rid of separate UTF-8 cell stuff: add 1 byte to cell and store BMP as |
| uint16_t+3 bits of flags. anything <=0xffff is Unicode, higher are used to |
| build tree of combined characters/non-BMP (LRU dropped when full) |
| - entry in FAQ about what to do when someone does mkdir /tmp/tmux-1000 |
| - monitor-activity is broken in several ways with multiple clients |
| - monitor-activity should be more powerful (eg set a region) |
| - maybe a way to put pane names instead of window names in status line |
| - support for borderless panes |
| - run-shell/if-shell should support status_replace stuff |
| - wait-pane command or another way to make it synchronous/wait for command to |
| finish |
| - last-pane across sessions |
| - attach should take a pane and select it as well as attaching |
| - panes should have names like windows |
| - command-prompt doesn't work if made read-only. why? |
| - option to quote format eg #{session_name:quoted} |
| - formats need conditions for >0 (for #P) |
| - fetch full command line on !Linux, and add option to strip prefixes |
| such as "sh " "/bin/sh " etc etc |
| - synchronize-windows option |
| - append to buffer in copy mode |
| - way to paste w/o trailing whitespace |
| - flag to switch-client to switch all clients |
| - history of layouts and undo/redo flags to selectl |
| - way to tag a layout as a number/name |
| - optimize pane redraws, 20120318184853.GK10965@yelena.nicm.ath.cx |
| - support multibyte key strings |
| - allow commands to be executed when certaing patterns in a screen |
| are clicked on with the mouse |
| - flag to make next/previous commands skip a window |
| - way to do tmux command/run-shell from mode keys |
| - send command to all windows |
| - choose-pane command |
| - Augment choose-tree to do this? TA to investigate. |
| - choose-mode and copy-mode are very similar. Perhaps make choose-mode a |
| subset of copy-mode in that it inherits key-bindings and other traits but |
| not all. |
| |
| TERMINAL ISSUES |
| ================ |
| |
| - use a better termcap internally instead of screen, perhaps xterm |
| - clear window title on exit (see using xterm title stack) |
| - get it passing all the vttest tests that don't require resizing the terminal |
| - support for bce |
| - use screen-256color when started on 256 colour terminal?? |
| - if-shell/run-shell should block further command execution in the same command |
| - possibly support rxvt-unicode extended mouse input (1015) |
| - wrap/no wrap esc seq DEC CSI ? 7 h/l |
| * We need a tmux terminfo entry to document the extensions we are using in |
| upstream terminfo. Must NOT change (only add or remove) anything from |
| TERM=screen so we can fallback! |
