display the current abbreviations
(show-abbreviations v w)
-- assuming that v and w currently abbreviate terms,
then this instruction displays them together with
the terms they abbreviate
-- display all abbreviations
Also see ACL2-pc::add-abbreviation for a general discussion of
abbreviations and see ACL2-pc::remove-abbreviations.
(show-abbreviations &rest vars)
Display each argument in vars together with the term it abbreviates
(if any). If there are no arguments, i.e. the instruction is simply
show-abbreviations, then display all abbreviations together with the
terms they abbreviate.
If the term abbreviated by a variable, say v, contains a proper
subterm that is also abbreviate by (another) variable, then both the
unabbreviated term and the abbreviated term (but not using (? v) to
abbreviate the term) are displayed with together with v.
