[Asdf-devel] ASDF and generated files

[Faré]

Dear Ralf,

congratulations for maintaining Common Music!
How does it compare to OpenMusic, these days?

Is this where the code is? I see nothing related to ASDF there:
http://sourceforge.net/p/commonmusic/code/HEAD/tree/trunk/

Regarding ASDF, I propose that you emulate the way cffi-grovel does it.

(defclass cm-scheme-file (cl-source-file) ((type :initform "scm")))
(defclass cm-scheme-to-lisp-op (non-propagating-operation))
(defmethod output-files ((o cm-scheme-to-lisp-op) (c cm-scheme-file)) ...)
(defmethod perform ((o cm-scheme-to-lisp-op) (c cm-scheme-file)) ...)
(defmethod component-depends-on ((o compile-op) (c cm-scheme-file))
   `((cm-scheme-to-lisp-op ,c) ,@(call-next-method)))
(defmethod input-files ((o compile-op) (c cm-scheme-file)) ...)

If your scheme to cl transformation itself depends on other files,
then instead of non-propagating-operation, make it something appropriate,
i.e. a selfward-operation on prepare-cm-scheme-to-lisp-op or something.
