This package adds debugging tools to Femlisp. This is a slightly modified version of the debugging suite proposed in (Norvig 1992).
When debugging on id print out the arguments args using the format in format-string.
When debugging id, print out the arguments args using the format in format-string with indentation given by indent.
Stop debugging on the passed symbols. With no arguments, stop debugging altogether.
Register ids for dbg.
Returns T if id-or-ids is in the debug list, NIL otherwise. If id-or-ids is a list, then every of its elements is checked if it is in the debug list.
Perform a check only if debugging id.
Execute body with debugging bound to ids.
