Alter how tmux handles the working directory to internally use file descriptors rather than strings. - Each session still has a current working directory. - New sessions still get their working directory from the client that created them or its attached session if any. - New windows are created by default in the session working directory. - The -c flag to new, neww, splitw allows the working directory to be overridden. - The -c flag to attach let's the session working directory be changed. - The default-path option has been removed. To get the equivalent to default-path '.', do: bind c neww -c $PWD To get the equivalent of default-path '~', do: bind c neww -c ~ This also changes the client identify protocol to be a set of messages rather than one as well as some other changes that should make it easier to make backwards-compatible protocol changes in future.

Support for windows larger than the client. This adds two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options, and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-width -x or -y. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and higher memory use if you make a window that big. The minimum size is the size required for the current layout including borders. This change allows some code improvements, most notably that since windows can now never be cropped, that code can be removed from the layout code, and since panes can now never be outside the size of the window, window_pane_visible can be removed.

Because pledge(2) does not allow us to pass directory file descriptors around, we can't use file descriptors for the working directory because we will be unable to pass it to a privileged process to tell it where to read or write files or spawn children. So move tmux back to using strings for the current working directory. We try to check it exists with access() when it is set but ultimately fall back to ~ if it fails at time of use (or / if that fails too).

Trying to do hooks generically is way too complicated and unreliable and confusing, particularly trying to automatically figure out what target hooks should be using. So simplify it: - drop before hooks entirely, they don't seem to be very useful; - commands with special requirements now fire their own after hook (for example, if they change session or window, or if they have -t and -s and need to choose which one the hook uses as current target); - commands with no special requirements can have the CMD_AFTERHOOK flag added and they will use the -t state. At the moment new-session, new-window, split-window fire their own hook, and display-message uses the flag. The remaining commands still need to be looked at.

Clean up and simplify tmux command argument parsing. Originally, tmux commands were parsed in the client process into a struct with the command data which was then serialised and sent to the server to be executed. The parsing was later moved into the server (an argv was sent from the client), but the parse step and intermediate struct was kept. This change removes that struct and the separate parse step. Argument parsing and printing is now common to all commands (in arguments.c) with each command left with just an optional check function (to validate the arguments at parse time), the exec function and a function to set up any key bindings (renamed from the old init function). This is overall more simple and consistent. There should be no changes to any commands behaviour or syntax although as this touches every command please watch for any unexpected changes.

Instead of every command resolving the target (-t or -s) itself, prepare the state (client, session, winlink, pane) for it it before entering the command. Each command provides some flags that tell the prepare step what it is expecting. This is a requirement for having hooks on commands (for example, if you hook "select-window -t1:2", the hook command should to operate on window 1:2 not whatever it thinks is the current window), and should allow some other target improvements. The old cmd_find_* functions remain for the moment but that layer will be dropped later. Joint work with Thomas Adam.

Originally, tmux commands were parsed in the client process into a struct with the command data which was then serialised and sent to the server to be executed. The parsing was later moved into the server (an argv was sent from the client), but the parse step and intermediate struct was kept. This change removes that struct and the separate parse step. Argument parsing and printing is now common to all commands (in arguments.c) with each command left with just an optional check function (to validate the arguments at parse time), the exec function and a function to set up any key bindings (renamed from the old init function). This is overall more simple and consistent. There should be no changes to any commands behaviour or syntax although as this touches every command please watch for any unexpected changes.

detached = args_has(args, 'd');
Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.

Both of cmdclient and curclient CAN be NULL - if the command is executed from the configuration file. In this case, attach-session can't do much, and new-session should just assume -d.

Because pledge(2) does not allow us to pass directory file descriptors around, we can't use file descriptors for the working directory because we will be unable to pass it to a privileged process to tell it where to read or write files or spawn children. So move tmux back to using strings for the current working directory. We try to check it exists with access() when it is set but ultimately fall back to ~ if it fails at time of use (or / if that fails too).

Support for windows larger than the client. This adds two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options, and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-width -x or -y. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and higher memory use if you make a window that big. The minimum size is the size required for the current layout including borders. This change allows some code improvements, most notably that since windows can now never be cropped, that code can be removed from the layout code, and since panes can now never be outside the size of the window, window_pane_visible can be removed.

Support for windows larger than the client. This adds two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options, and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-width -x or -y. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000.

If multiple arguments are given to new-session, new-window, split-window, respawn-window or respawn-pane, pass them directly to execvp() to help avoid quoting problems. One argument still goes to "sh -c" like before. Requested by many over the years. Patch from J Raynor.

Instead of every command resolving the target (-t or -s) itself, prepare the state (client, session, winlink, pane) for it it before entering the command. Each command provides some flags that tell the prepare step what it is expecting. This is a requirement for having hooks on commands (for example, if you hook "select-window -t1:2", the hook command should to operate on window 1:2 not whatever it thinks is the current window), and should allow some other target improvements. The old cmd_find_* functions remain for the moment but that layer will be dropped later. Joint work with Thomas Adam.

Alter how tmux handles the working directory to internally use file descriptors rather than strings. - Each session still has a current working directory. - New sessions still get their working directory from the client that created them or its attached session if any. - New windows are created by default in the session working directory. - The -c flag to new, neww, splitw allows the working directory to be overridden. - The -c flag to attach let's the session working directory be changed. - The default-path option has been removed. To get the equivalent to default-path '.', do: bind c neww -c $PWD To get the equivalent of default-path '~', do: bind c neww -c ~ This also changes the client identify protocol to be a set of messages rather than one as well as some other changes that should make it easier to make backwards-compatible protocol changes in future.

Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.

Use a utility function for common code to show errors in config file, from Thomas Adam.

Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.

Mouse bindings and hooks set up an initial current state when running a command. This is used for the session, window and pane for all commands in the command sequence if there is no -t or -s. However, using it for all commands in the command sequence means that if the active pane or current session is changed, subsequent commands still use the previous state. So make commands which explicitly change the current state (such as neww and selectp) update it themselves for later commands. Commands which may invalidate the state (like killp) are already OK because an invalid state will be ignored. Also fill in the current state for all key bindings rather than just the mouse, so that any omissions are easier to spot.

Rewrite command queue handling. Each client still has a command queue, but there is also now a global command queue. Instead of command queues being dispatched on demand from wherever the command happens to be added, they are now all dispatched from the top level server loop. Command queues may now also include callbacks as well as commands, and items may be inserted after the current command as well as at the end. This all makes command queues significantly more predictable and easier to use, and avoids the complex multiple nested command queues used by source-file, if-shell and friends. A mass rename of struct cmdq to a better name (cmdq_item probably) is coming.

Alter how tmux handles the working directory to internally use file descriptors rather than strings. - Each session still has a current working directory. - New sessions still get their working directory from the client that created them or its attached session if any. - New windows are created by default in the session working directory. - The -c flag to new, neww, splitw allows the working directory to be overridden. - The -c flag to attach let's the session working directory be changed. - The default-path option has been removed. To get the equivalent to default-path '.', do: bind c neww -c $PWD To get the equivalent of default-path '~', do: bind c neww -c ~ This also changes the client identify protocol to be a set of messages rather than one as well as some other changes that should make it easier to make backwards-compatible protocol changes in future.
