Fedora Formal Methods Special Interest Group (SIG)

What are Formal Methods?

"Formal methods" are techniques that use mathematics to prove that models of software, hardware, or systems will or will not have certain behavior. To be practical, they must be automated using tools. Free/Libre/Open Source Software (FLOSS) formal methods tools are now available, including automated theorem provers and model-checkers, but the tools can be difficult to install and apply.

Goal and Scope

The goal of the Formal Methods SIG is to make it easy to install formal methods tools in Fedora, ease learning how to apply them, encourage the development of "open proofs" (where an implementation, proofs, and required tools are all FLOSS), and to provide feedback to toolmakers so that the tools in Fedora can become more powerful, more scaleable, and easier to use together.

Mission and Plan

For more details, see the Mission Statement and Plan for the Formal Methods Fedora SIG.

Communication

The SIG will use the Fedora wiki, of course. Material that crosses beyond Fedora may also go into the open proofs site.

The mailing list to use is TBD:

Tasks

Recently Completed

  • Package "Why" updated to version 2.23 (needed for frama-C)
  • Package PVS; now packaged as pvs-sbcl

Ongoing

The following packages are our current focus and have someone working on them:

  • Package critically-needed pvs libraries, so "Why" can invoke them (jjames)
  • Update "Why" so it can invoke pvs-sbcl (jjames)
  • Package frama-c (adunn)
  • Package ACL2 (jjames looking at)

Top to-dos

For packages that we'd like to see created, see the Open Proofs packaging status page. Jerry James has draft packages for some of these.

Of those, in particular it'd be great to see:

  • Package APRON (a draft is available)
  • Package Isabelle/HOL
  • Package DiVinE-MC (a draft is available)

Yum group

We intend to create a "formal methods" yum group soon, so that 'yum groupinstall "Formal methods"' will get you lots of packagey goodness. The current plan is to wait until frama-c is packaged, though if that takes too long, we can go ahead.

This would include at least the following packages (with their dependencies): E, alt-ergo, coq (coq-coqide, coq-doc, coq-emacs), cvc3, emacs-proofgeneral (emacs-common-proofgeneral, emacs-proofgeneral-el.noarch), xemacs-proofgeneral (xemacs-proofgeneral-el), frama-c {TODO}, minisat2, ppl (ppl-*), prover9 (prover9-apps, prover9-devel, prover9-doc), pvs-sbcl, sat4j, splint, stp (stp-devel), tex-zfuzz, why (why-coq, why-gwhy), zenon.

Fedora Features

We could make this a proposed feature for the next release of Fedora; see the Fedora Features policy.

Spin

In the longer term, we hope to create a Fedora Spin with these packages. That will need to wait until after the yum group is formed.
