The impetus for this question is, I have subclassed cl-source-file with
org-source-file and have defined tangle-op (as a subclass of both
sideway-operation and upward-operation). my perform method is:
(defmethod perform ((op tangle-op) (file org-source-file))
(let* ((input-file (first (input-files op file)))
(output-file (first (output-files op file))))
(tangle input-file output-file)))
where (tangle input-file output-file) runs emacs in batch mode to produce a
lisp source file.
How can I define my input-files and output-files methods to make the lisp
source files appear in some build directory maintained by ASDF, rather than in
my source tree?
thanks,
Phoebe
