wezterm.shell_join_args({"foo", "bar"})

{{since('20220807-113146-c2fee766')}}

wezterm.shell_join_args joins together its array arguments by applying posix style shell quoting on each argument and then adding a space.

> wezterm.shell_join_args{"foo", "bar"}
"foo bar"
> wezterm.shell_join_args{"hello there", "you"}
"\"hello there\" you"

This is useful to safely construct command lines that you wish to pass to the shell.
