io.github.libtmux.Options.Options.setExpanded(name: String, format: String) -> void
```

Sets one option to what a tmux format comes to, rather than to the format itself.

{@code setExpanded("status-left", "in #{session_name}")} stores {@code in base}. The
expansion happens once, when this is called; the option does not stay live.

Because tmux expands the format when this is called, a {@code #(...)} in it runs a command
at that moment. Pass any interpolated value through {@link TmuxFormats#literal} unless you mean
it to be expanded.
