server.Server.display_popup

This needs a client with a terminal, so it fails on a server nothing is attached to.

Unlike Self::command_prompt and Self::display_menu , this does not wait for a person -- but it does wait for the command. The popup is opened with -E, so it closes when what runs inside it exits, and this returns then. A command that does not end holds the call until the dispatch timeout does.

Errors

Returns Error::ServerMismatch when the client belongs to another server, or an error when no suitable client exists, when tmux refuses the command, and when the dispatch timeout expires before it exits.
