Hey, I was looking around for samples of Isabelle code and I ran across the "archive of formal proofs" at https://www.isa-afp.org/index.html . But, it seems like it is a bunch of PDFs. Do people use that in some way? Is there something like, a github repository with this code?

well, i managed to prove this great work of mathematics:

lemma foo: "2 + 2 = 4"
  by auto

If you go to the 'About' link on the menu on the left, you can find your way to a repository. You can also download all the entries from the 'Download' link on the left. Or you can browse the theory files in each entry from the 'Browse theories' link in the page for each entry.

ok cool. do you know if there's any particular reason this doesn't use github?

On the one hand: why would they use github?

On the other hand: historically, isabelle uses mercurial and github only supports git. And some people complain loudly about github.

i was just curious because i looked on github first and didn't see anything. but it makes sense if isabelle folks are attached to mercurial
