<p dir="auto">Dear Greg,</p>
<p dir="auto">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.</p>
<p dir="auto">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: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">clinit.cl</code>, <code style="margin: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">.sbclrc</code>, etc. -- indeed I point all of those at one single <code style="margin: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">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!).</p>
<p dir="auto">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="color: #3983C4;">here</a>.</p>
<p dir="auto">I don't understand Windows enough to understand this piece of text from the ASDF manual:</p>
</div><div class="plaintext" style="white-space: normal;"><blockquote style="margin: 0 0 5px; padding-left: 5px; border-left: 2px solid #777777; color: #777777;"><p dir="auto">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.</p>

<div class="markdown" style="white-space: normal;">
<p dir="auto">The relevant code may be found in <a href="https://gitlab.common-lisp.net/asdf/asdf/-/blob/release/uiop/configuration.lisp" style="color: #3983C4;">uiop/configuration.lisp</a>. It looks like invoking the functions <code style="margin: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">uiop:xdg-config-home</code> and <code style="margin: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">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: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">(uiop:xdg-data-dirs "config/")</code> -- maybe see what that evaluates to on your Windows box?</p>
<p dir="auto">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.</p>
<p dir="auto">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: 0 0; padding: 0 0.25em; border-radius: 3px; background-color: #F7F7F7;">common-lisp.net</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).</p>
<p dir="auto">Good luck!<br>
R</p>

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