Examples: (set-inhibit-output-lst '(warning)) (set-inhibit-output-lst '(proof-tree prove proof-checker)) (set-inhibit-output-lst *valid-output-names*) ; inhibit all prover output :set-inhibit-output-lst (proof-tree prove) General Form: (set-inhibit-output-lst lst)where
lst is a form (which may mention state) that evaluates
to a list of names, each of which is the name of one of the
following ``kinds'' of output produced by ACL2.
error error messages
warning warnings other than those related to soundness
warning! warnings (of all degrees of importance)
observation observations
prove commentary produced by the theorem prover
proof-checker commentary produced by the proof-checker
event non-proof commentary produced by events such as defun
and encapsulate
expansion commentary produced by make-event expansion
summary the summary at the successful conclusion of an event
proof-tree proof-tree output
It is possible to inhibit each kind of output by putting the
corresponding name into lst. For example, if 'warning is
included in (the value of) lst, then no warnings are printed
except those related to soundness, e.g., the inclusion of an
uncertified book. Note that proof-tree output is affected by
set-inhibit-output-lst; see proof-tree.See with-output for a variant of this utility that can be used in books. Also see set-inhibit-warnings for how to inhibit individual warning types and see set-inhibited-summary-types for how to inhibit individual parts of the summary.
Printing of events on behalf of certify-book and encapsulate is
inhibited when both 'event and 'prove belong to lst. Otherwise,
printing of events is controlled by the ld special
ld-pre-eval-print.
Note for advanced users. By including warning! in lst, you are
automatically including warning as well: all warnings will be inhibited.
This is not the case if you modify value of state global variable
'inhibit-output-lst directly (with assign or f-put-global);
then, if you include warning! but not warning, then warnings not
related to soundness will still be printed (which is probably not what was
intended).
