Sweep integrates with the Emacs minor mode ElDoc, which automatically displays documentation for the predicate at point. Whenever you move the cursor into a predicate definition or invocation, ElDoc displays the signature and summary of that predicate in the echo area at the bottom of the frame.
Whether to enable ElDoc support in sweeprolog-mode buffers.
Defaults to t.
To disable the ElDoc integration in Sweep Prolog mode buffers,
customize the user option sweeprolog-enable-eldoc to
nil.
See (emacs)Programming Language Doc, for more information about ElDoc and its customization options.
