Method combination and ASDF
by Robert Goldman 25 Apr '24

25 Apr '24

An issue that came up discussing ASDF-FLV with Didier has to do with outside modification to exported ASDF generic functions. I think it's unambiguously reasonable to say "if you mess with unexported functions, generic or otherwise, you're on your own, and could break things arbitrarily." But I don't think ASDF has established clear expectations about extending methods of exported ASDF generic functions. I think there's been an unspoken assumption that if ASDF generic functions are to be extended, particularly by `:around`, `:before`, and `:after` methods, there should be some novel class introduced that will be used to select extensions. So, for example, it's fine to wrap or write new methods for `perform`, but not for existing component and operation classes. Doing so means that a change one might think appropriate for one's own library bleeds out into other code that one has no way of predicting, and also has the potential to collide with ASDF's own code or other people's ASDF extensions. Those are good reasons for this convention -- no modification without introducing new classes for method dispatch -- but ASDF-FLV is an example of a system that wants to introspect about the entire running lisp image. I'd be interested in hearing what people think about this kind of case. Should we introduce, for example, an `ASDF` object that extenders could add mixins to in order to enable modifications to ASDF behavior that aren't limited to a single library? Please post any thoughts you have about this idea.

Loading only fasl files
by Greg Bennett 21 Apr '24

21 Apr '24

Hello from Greg Bennett who is trying to debug some compilation issues in Allegro. I have what I believe to be a completely compiled project, consisting of several systems, and I would like to load only its fasl files. Specifically I do not want to re-compile the source files which would replace those fasls. I have looked at the manual in the hope that load-bundle-op might work, but I see that this requires *compiling* the source into a single fasl. Perhaps (probably!) I'm missing something. Any advice/assistance much appreciated. Cheers Greg

This may be a duplicate query. I posted from another account which bounced. This may be the account with which I an 'registered'. Apologies for the noise.
