Hi Robert,
AFAIU this is the configuration of ASDF itself, when loading in a fresh CL. I think we are not clear about the timing of what should be loaded when.
CLAD does not need ASDF or UIOP. It just has a .asd file because Quicklisp asks for it.
Cheers

TBQH, I am not as sure as I should be. I try to avoid all the configuration that happens while ASDF loads, so that I configure only *after* the load is complete, at a point where I can watch what goes on. As I have said before, I don't like the configuration that uses config files, environment variables or magic directories, because it's impossible to debug (by the time ASDF is loaded and can be instrumented, it's too late).
I believe the right thing would be for you to figure out how to add an entry to the variable asdf:*default-source-registries* that is a function that will collect the appropriate configuration information. But I don't claim to fully understand source-registry.lisp https://gitlab.common-lisp.net/asdf/asdf/-/blob/9c7f1b76ca8e820c020a3ec3aeb4b507ab15aa34/source-registry.lisp .

Sure.
I am not privy to ASDF bootstrap. Where would you start?

The next step would be to add an ASDF plug-in so that ASDF can read its configuration from a CLAD set up…. :-)

Wellll. You need a CL to load ASDF, don’t you? :)
CLAD is minimal and barebones. You can load it from two files (just because the DEFPACKAGE is separate) and it’s there. Look ma! No ASDF! :) (Or UIOP)
But I see your point. Time to add a clad-setup.lisp file.

I do like the idea of CLAD, but in this case isn't there a Catch-22? You need to configure ASDF in order to load CLAD, so you can't use CLAD to configure ASDF, can you?

Dear Greg,
Thanks for the kind words! I am not sure why I didn't see your post on ASDF-devel, but I didn't. And I have seen several requests for moderation, so the list seems live. In case my response is interesting to the group, I am responding to the list as well.
A couple of disclaimers: (1) I haven't used Windows in more than a decade, and (2) I don't use these configuration files. I find I'm happier to keep all of my lisp configuration in lisp configuration files ( clinit.cl, .sbclrc, etc. -- indeed I point all of those at one single lisp-config.lisp file), instead of having to hunt through multiple files in multiple locations for this information. So take anything I say with more than a grain of salt (given your cardiologist approves!).
That said, these config files are placed according to the XDG standard which... as far as I can tell only applies to linux, and not to either Windows or MacOS. So there's code in ASDF/UIOP that extends XDG to other platforms. ASDF documentation about XDG can be found here https://asdf.common-lisp.dev/asdf.html#XDG-base-directory.
I don't understand Windows enough to understand this piece of text from the ASDF manual:
Since support for querying the Windows registry is not possible to do in reasonable amounts of portable Common Lisp code, ASDF 3 relies on the environment variables that Windows usually exports, and are hopefully in synch with the Windows registry. If you care about the details, see uiop/configuration.lisp and don’t hesitate to suggest improvements.
The relevant code may be found in uiop/configuration.lisp https://gitlab.common-lisp.net/asdf/asdf/-/blob/release/uiop/configuration.lisp. It looks like invoking the functions uiop:xdg-config-home and uiop:xdg-config-pathnames might help you figure out where ASDF is looking. But I don't really understand the discussion about the registry above. I do see a bit of code that says that UIOP (and thus ASDF) look for configs in the value of (uiop:xdg-data-dirs "config/") -- maybe see what that evaluates to on your Windows box?
I hope that these snippets have been helpful, and if you find the answers you seek, please send to me and ASDF-devel, so that the information will be available to others.
It might be a good thing if someone with the resources would gift a Windows resource to the CL Foundation to hook into common-lisp.net so that the community doesn't have to rely on this kind of guesswork. I note that ASDF is no longer tested on Windows at all, since I don't have access to a Windows VM and even if I did, I wouldn't know how to use it (nor do I have the time to learn).
Good luck! R

Good evening Robert,
Some longish time ago you were kind enough to help me with ASDF matters. I posted recently to asdf-devel, largely in the hope that you might see it, I confess.
Web search has, so far, not been helpful, I'm afraid.
I shall quite understand if you do not reply; your inbox must receive lots of this sort of thing.
I have a test system in c:/ASDF/asdf-tests/ copied from the linux directory /home/gwbennett/ASDF/asdf-tests/
Under Linux in my source-registry.conf.d directory I have the file gb-source.conf with the one line (:tree "/home/gwbennett/ASDF/asdf-tests/")
Then in sbcl I can issue (asdf:load-system "gb-a") and all is well.
I have tried various spots for gb-source.conf under Windows, all without success:
c:\Users\Greg\AppData\Local\config\common-lisp\source-registry.conf.d\
c:\Users\Greg\
c:\Users\Greg\AppData\
c:\Users\Greg\AppData\Local\
If I issue, old style, (push "c:/ASDF/asdf-tests/" asdf:*central-registry*) then all is well.
Perhaps there is no place for a config file under W!
Cheers
Greg
