Hi. I'm happy to help you work through this, but so that it doesn't recur as a problem, I'd appreciate it if you would help me fix the manual's discussion of this.

First, have you read this page https://common-lisp.net/project/asdf/asdf.html#Creating-new-operations ?

Please have a look at that -- it's not very long -- and let us know what more needs to be supplied.

I note the discussion of operation-done-p. I suspect that is your problem -- your new operation is not aware that it needs to be performed.

This page is substantially redundant with the pages on the object model, and should be beefed up with cross-references, and more inclusion of docstrings...

Hi

I am trying to create a new ASDF:OPERATION, but I must be missing something and the manual (or Google) does not seem to help much.

How do you create a new operation, which may be quite simple?  Or better, how do you get PERFORM and/or OPERATE to actually do something for you.

I know I should RTFM, but in this case it is more of a RTFC, which is far more difficult.

I tried the following

(defclass my-op (non-propagating-operation) ())

(defmethod perform ((o my-op) (s system))

   (print 42))

(defmethod operate ((o my-op) (s system) &key &allow-other-keys)

   (print 666))

But then, doing

cl-user 42> (operate 'my-op (find-system "somesys") :bar 1024)

#<MY-OP >

#<ASDF/PLAN:SEQUENTIAL-PLAN 2301B97B>

is all I get.

Any tutorial or advice?

Thanks
