front-end/interaction in drscheme:language:language<%>

This method is just like front-end/complete-program except that it is called with program fragments, for example the expressions entered in the interactions window. It is also used in other contexts by tools to expand single expressions.

• (send a-drscheme:language:language front-end/interaction port line-col-offset settings teachpack-cache) -> (-> (union sexp syntax eof))
     port : port
     line-col-offset : (union false? (list/p (union false? number?) (union false? number?) (union false? number?)))
     settings : settings
     teachpack-cache : drscheme:teachpack:teachpack-cache

  The line-col-offset argument specifies the initial line, column, and offset for the text to be read from the port. If it is #f, a default value, (list 1 0 0) is used. See read-syntax for details on this argument. It should match read-syntax's last argument.
