Hallo,
Dana Scott just asked me why he could not get the AFP entry
Incompleteness to work. I tried it myself and found that the entry makes
use of Nominal2, but Nominal2 is not an AFP entry itself, nor is it
available anywhere else. All I found is an old version that works with
Isabelle 2014.
Strangely, when clicking ‘Browse theories’ in the Incompleteness AFP
entry, some Nominal2 theories show up, but when downloading the .tar.gz
(‘Download this entry’), they are not in the archive.
What is the current status of Nominal2, especially in combination with
Incompleteness? Having an AFP entry online that does not work when you
download it and load it into Isabelle seems highly undesirable to me.
Cheers,
Manuel

This is weird. It is definitely in the mercurial repository, but it doesn’t appear as an individual entry. This means that you have to download the entire AFP, all 144 MB, if you want to get it. I think that this has been the situation for a considerable time.
It’s worth mentioning that Incompleteness takes several minutes to run, even on a fast machine.

How about downloading it from the official Nominal Isabelle site:
http://www.inf.kcl.ac.uk/staff/urbanc/Publications/Nominal2-2014.tgz
I don't know though if the incompleteness proof works with this version.

That's Isabelle 2014. It doesn't work with the current version of
Isabelle. Since Incompleteness depends on Nominal2, is in the AFP, and
works in the automatic tests (I think), there must be an up-to-date
version of Nominal2. The question is just: Where is it?

I've always found the official AFP website a bit inconvenient wrt. entries
that depend on other entries; in practice I am always using a repository
clone (official or devel).
For Nominal2, the situation seems to be worse, since it is not even an
official entry -- which I did not know before, but I am not an AFP editor,
just a maintainer.
Here is the relevant changeset history with the typical dry humor
of changelog entries:

The last change merely formalizes the de-facto situation that Nominal2 is
a permanent part of AFP. IIRC, it was also based on some private
discussions with Christian Urban and/or Gerwin Klein.

What’s going on is that Nominal2 is not an official entry, so has no website entry and no separate tar file to download.
Nominal2 was supposed to go into the Isabelle distribution and replace Nominal. This has not happened in over a year, and I’m not happy with this situation. It should either become a real entry or be removed.
Currently, the best way to get it is to download the whole AFP release (from the download link in the navigation panel on the left).

Gerwin

Hello,
With the following download links I was successful (14.06.2015):
http://www.cl.cam.ac.uk/research/hvg/Isabelle/dist/Isabelle2015.dmg

Just to add that I updated my nominal web-page with a
current version of Nominal2 for Isabelle 2015. Sorry, I
was still running Isabelle 2014 and somehow forgot to
do this.
Please let me know if there is anything not working
or not available.
Best wishes,
Christian
