Hi all,

Is there a way to load a system directly, leaving everything else (source-registry configuration, *central-registry*, or what not) alone?

I hacked up something to do this,

(asdf:load-system #P"c:/blah/blah/cl-ppcre-1.2.19/cl-ppcre.asd")

so that there's no need to worry about specific versions or setting up paths to a specific library. If the library being loaded depends on other modules, then we return to searching the source-registry as if by typing this before loading our system:

(asdf:load-system <lib-depended-upon>)

Does asdf already support this? Will such a feature be useful?

I don't know whether we ever returned to this. In essence, I think it would be great to have this incorporated. Here's the problem I can see: what do we do about .asd files that contain multiple DEFSYSTEM forms. E.g., my files that have DEFSYSTEM FOO and DEFSYSTEM FOO-TEST? Or what about McCLIM, whose asd file has a boatload of back-end systems?

What about tweaking this a little bit so that we support a :system-filename keyword argument, instead of taking the primary argument?

E.g.,

(asdf:load-system 'cl-ppcre :system-pathname #P"c:/blah/blah/cl-ppcre-1.2.19/cl-ppcre.asd")

?

That would solve the problems above about many-to-one system to file mappings.
