have each function compiled as you go along.
Major Section:  EVENTS

Example Forms:
(set-compile-fns t)    ; new functions compiled after DEFUN
(set-compile-fns nil)  ; new functions not compiled after DEFUN
Note: This is an event! It does not print the usual event summary but nevertheless changes the ACL2 logical world and is so recorded.

Also see comp, because it may be more efficient in some Common Lisps to compile many functions at once rather than to compile each one as you go along.

General Form:
(set-compile-fns term)
where term is a variable-free term that evaluates to t or nil. This macro is equivalent to
(table acl2-defaults-table :compile-fns term)
and hence is local to any books and encapsulate events in which is occurs; see acl2-defaults-table. However, unlike the above simple call of the table event function (see table), no output results from a set-compile-fns event.

Set-compile-fns may be thought of as an event that merely sets a flag to t or nil. The flag's effect is felt when functions are defined, as with defun. If the flag is t, functions are automatically compiled after they are defined, as are their executable counterparts (see executable-counterpart). Otherwise, functions are not automatically compiled. Because set-compile-fns is an event, the old value of the flag is restored when a set-compile-fns event is undone.

Even when :set-compile-fns t has been executed, functions are not individually compiled when processing an include-book event. If you wish to include a book of compiled functions, we suggest that you first certify it with the compilation flag set; see certify-book. More generally, compilation via set-compile-fns is suppressed when the state global variable ld-skip-proofsp has value 'include-book.
