Set-raw-warning-format

Print some warnings in a ``raw'', s-expression format

General Forms:
(set-raw-warning-format t)
:set-raw-warning-format t
(set-raw-warning-format nil)
:set-raw-warning-format nil

This command affects 'warning (and 'warning!) output from the theorem prover when not inhibited (see set-inhibit-output-lst). Calling this macro with value t as shown above will cause warnings to be printed in a ``raw'', s-expression format, of the form (:WARNING warning-type alist). The following example shows a traditional warning message followed by its counterpart after evaluating (set-raw-warning-format t).

; default format
ACL2 Warning [Subsume] in ( DEFTHM APP-COMMUTES ...):  A newly proposed
:REWRITE rule generated from APP-COMMUTES probably subsumes the previously
added :REWRITE rule APP-CONS, in the sense that the new rule will now
probably be applied whenever the old rule would have been.

; raw format
(:WARNING "Subsume"
          ((:CTX (DEFTHM . APP-COMMUTES))
           (:NEW-RULE APP-COMMUTES)
           (:RULE-CLASS-NEW :REWRITE)
           (:RULE-CLASS-OLD :REWRITE)
           (:SUBSUMED-RULES (APP-CONS))))

As illustrated above, it is typical that in the raw format, the :CTX entry is first in the alist while the others are ordered alphabetically by key (e.g., :NEW-RULE precedes :RULE-CLASS-NEW alphabetically).

To obtain the current raw-warning-format (t if that format is active, nil if not), evaluate (@ raw-warning-format).

NOTE: Only a few commonly-occurring classes of warnings are shown differently in raw-warning-format.
