<p dir="auto">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 <em>after</em> 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).</p>
<p dir="auto">I believe the right thing would be for you to figure out how to add an entry to the variable <code style="margin:0 0;padding:0 0.25em;border-radius:3px;background-color:#f7f7f7">asdf:*default-source-registries*</code> that is a function that will collect the appropriate configuration information.

<p dir="auto" style="font-family:sans-serif"><span>Dear Greg,</span></p>
<p dir="auto" style="font-family:sans-serif"><span>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.</span></p>
<p dir="auto" style="font-family:sans-serif"><span>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 (<code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)"><a href="http://clinit.cl" style="font-family:monospace" rel="noreferrer noreferrer" target="_blank">clinit.cl</a></code>, <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)">.sbclrc</code>, etc. -- indeed I point all of those at one single <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)">lisp-config.lisp</code> 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!).</span></p>
<p dir="auto" style="font-family:sans-serif"><span>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 <a href="https://asdf.common-lisp.dev/asdf.html#XDG-base-directory" style="font-family:sans-serif;color:rgb(57,131,196)" rel="noreferrer noreferrer" target="_blank">here</a>.</span></p>
<p dir="auto" style="font-family:sans-serif"><span>I don't understand Windows enough to understand this piece of text from the ASDF manual:</span></p>

<p dir="auto" style="font-family:sans-serif"><span>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.</span></p>

<p dir="auto" style="font-family:sans-serif"><span>The relevant code may be found in <a href="https://gitlab.common-lisp.net/asdf/asdf/-/blob/release/uiop/configuration.lisp" style="font-family:sans-serif;color:rgb(57,131,196)" rel="noreferrer noreferrer" target="_blank">uiop/configuration.lisp</a>. It looks like invoking the functions <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)">uiop:xdg-config-home</code> and <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)">uiop:xdg-config-pathnames</code> 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 <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)">(uiop:xdg-data-dirs "config/")</code> -- maybe see what that evaluates to on your Windows box?</span></p>
<p dir="auto" style="font-family:sans-serif"><span>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.</span></p>
<p dir="auto" style="font-family:sans-serif"><span>It might be a good thing if someone with the resources would gift a Windows resource to the CL Foundation to hook into <code style="margin:0px;padding:0px 0.25em;border-radius:3px;font-family:monospace;background-color:rgb(247,247,247)"><a href="http://common-lisp.net" style="font-family:monospace" rel="noreferrer noreferrer" target="_blank">common-lisp.net</a></code> 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).</span></p>
