Examples: (current-theory :here) (current-theory 'lemma3)See logical-name.
General Form: (current-theory logical-name)Returns the current theory as it existed immediately after the introduction of
logical-nameprovided it is evaluated in an environment in which the variable symbol WORLD is bound to the current ACL2 logical world,
(w state). Thus,
ACL2 !>(current-theory :here)will cause an (unbound variable) error while
ACL2 !>(let ((world (w state))) (current-theory :here))will return the current theory in world.
See theories and see logical-name for a discussion of
theories in general and why the commonly used ``theory functions''
current-theory are really macros that expand into terms
involving the variable
The theory returned by

You may experience a fencepost problem in deciding which logical
name to use.
Deflabel can always be used to mark unambiguously for
future reference a particular point in the development of your
