wezterm.mux.spawn_window{}

Since: 20220624-141144-bd1b7c5d

Spawns a program into a new window, returning the MuxTab, MuxPane and MuxWindow objects associated with it:

local tab, pane, window = wezterm.mux.spawn_window {}

When no arguments are passed, the default program is spawned.

The following parameters are supported:

args

Specifies the argument array for the command that should be spawned. If omitted the default program for the domain will be spawned.

wezterm.mux.spawn_window { args = { 'top' } }

cwd

Specify the current working directory that should be used for the program.

If unspecified, follows the rules from default_cwd

wezterm.mux.spawn_window { cwd = '/tmp' }

set_environment_variables

Sets additional environment variables in the environment for this command invocation.

wezterm.mux.spawn_window { set_environment_variables = { FOO = 'BAR' } }

domain

Specifies the multiplexer domain into which the program should be spawned. The default value is assumed to be "DefaultDomain", which causes the default domain to be used.

You may specify the name of one of the multiplexer domains defined in your configuration using the following:

wezterm.mux.spawn_window { domain = { DomainName = 'my.name' } }

width and height

Only valid when width and height are used together, allows specifying the number of column and row cells that the window should have.

wezterm.mux.spawn_window { width = 60, height = 30 }

workspace

Specifies the name of the workspace that the newly created window will be associated with. If omitted, the currently active workspace name will be used.

wezterm.mux.spawn_window { workspace = { 'coding' } }
