Examples: (set-invisible-fns-table ((binary-+ unary--) (binary-* unary-/) (unary-- unary--) (unary-/ unary-/))) (set-invisible-fns-table t) ; restore original invisible-fns-tableAmong other things, the setting above has the effect of making

(unary-- arg)will be given the same weight and will be permuted so as to be adjacent. The form
(invisible-fns-table (w state))returns the current value of the invisible functions table.
Also see add-invisible-fns and see remove-invisible-fns for events that add to and remove from the invisible functions table.
General Form: (set-invisible-fns-table alist)where
tor a true list of pairs, each element of which is of the form
(fn ufn1 ... ufnk), where
fnis a function symbol and each
ufniis a unary function symbol. When alist is
t, the initial value of this table is used in its place. Modulo the replacement of
alistby the default setting when
t, this macro is equivalent to
(table invisible-fns-table nil 'alist :clear)which is also an event (see table).
See invisible-fns-table for a description of the invisible functions table.
