The text user interface (TUI) in Fluent, also referred to as The Console, is written in a dialect of Lisp called Scheme. Users familiar with Scheme will be able to use the interpretive capabilities of the interface to create customized commands. The text-based menu system provides a hierarchical interface to the underlying procedural interface of the program.
You can easily manipulate its operation with standard text-based tools—input can be saved in files, modified using text editors, and read back in to be executed.
The text menu system is tightly integrated with the Scheme extension language, so it can easily be programmed to provide sophisticated control and customized functionality.
A more complete description of the text-based interface, including a full list of commands is available in Fluent Text Command List.
