Example Form: (add-include-book-dir :smith "/u/smith/") ; For (include-book "foo" :dir :smith), prepend "/u/smith/" to "foo". General Form: (add-include-book-dir kwd dir)where
diris the pathname of a directory. (If the final '
/' is missing, ACL2 will add it for you.) The effect of this event is to modify the meaning of the
:dirkeyword argument of
include-bookas indicated by the examples above, and similarly for
ld, namely by associating the indicated directory with the indicated keyword for purposes of the
:dirargument. By the ``indicated directory'' we mean, in the case that the pathname is a relative pathname, the directory relative to the current connected book directory; see cbd. See delete-include-book-dir for how to undo this effect.
A keyword that is already associated with a directory string by an existing
add-include-book-dir cannot be associated with a different
directory string. If that is your intention, first apply
delete-include-book-dir to that keyword; see delete-include-book-dir.
If however the new directory string is identical with the old, then the call
add-include-book-dir will be redundant (see redundant-events).
:system can never be redefined. It will always point to the
absolute pathname of the system books directory, which by default is
immediately under the directory where the ACL2 executable was originally
built (see include-book, in particular the discussion there of ``books
This macro generates (in essence) a call
(table acl2-defaults-table :include-book-dir-alist ...)
and hence is
local to any books and
in which it occurs. See acl2-defaults-table. Even if you invoke
add-include-book-dir before certifying a book, so that this event is
among the book's portcullis commands rather than in the book itself,
add-include-book-dir event will not be visible after
the book is included. (Note: The above behavior is generally preserved in
raw-mode (see set-raw-mode),though by means other than a table.)
