DEFAULT-RULER-EXTENDERS.html -- ACL2 Version 6.3

## DEFAULT-RULER-EXTENDERS

the default ruler-extenders for `defun`'d functions

    Major Section:  MISCELLANEOUS

When a `defun` is processed and no `:ruler-extenders` `xarg` is supplied, the function `default-ruler-extenders` is used to obtain the current ruler-extenders; see ruler-extenders. To find the default ruler-extenders of the current ACL2 world, type `(default-ruler-extenders (w state))`.

While events that change the default ruler-extenders are permitted within an `encapsulate` or the text of a book, their effects are `local` in scope to the duration of the encapsulation or inclusion. See default-defun-mode for an analogous discussion for defun-modes.
