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 '#{pane_current_path}' The equivalent of default-path '~' is left as an exercise for the reader. 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.

#define SPLIT_WINDOW_TEMPLATE "#{session_name}:#{window_index}.#{pane_index}"
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.

Add resize-pane -Z to temporary zoom the active pane to occupy the full window or unzoom (restored to the normal layout) if it already zoomed, bound to C-b z by default. The pane is unzoomed on pretty much any excuse whatsoever. We considered making this a new layout but the requirements are quite different from layouts so decided it is better as a special case. Each current layout cell is saved, a temporary one-cell layout generated and all except the active pane set to NULL. Prompted by suggestions and scripts from several. Thanks to Aaron Jensen and Thiago Padilha for testing an earlier version.

Sync OpenBSD patchset 829: 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.

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.
