From The Twelf Project
Mechanizing Metatheory with LF and Twelf
Do you want to learn how to use Twelf to specify, implement, and prove properties about programming languages?
Come to the Twelf tutorial on January 19, 2009, co-located with POPL 2009, in Savannah, Georgia.
under the helpful guidance of Twelf experts.
The tutorial will be a highly interactive introduction to LF and Twelf aimed at programming languages researchers. No prior experience with LF and Twelf is presumed. Participants will leave the workshop with experience in reading and writing LF representations of programming languages, and experience reading, writing, and debugging Twelf proofs.
Register at the POPL 2009 registration site!
The tutorial is organized and presented by the CMU Principles of Programming group. The presenters and TAs at POPL will be Dan Licata, William Lovas, Chris Martens, Rob Simmons, Bob Harper, and Karl Crary.
The tutorial will begin at 9:00AM. Get the slides!
- Part 1: Basic Twelf Skills
- Part 2: Mechanizing MinML
- Part 3: Combinators: Worlds and Adequacy
- Coda: What's next?
There will be a morning coffee break (10AM), lunch (12:30PM-1:30PM), and an afternoon coffee break (3PM).
Get Twelf before the tutorial!
The tutorial will be interactive, with participants writing Twelf code, so you should come with Twelf installed on your laptop.
Pre-built binaries of Twelf are available for most operating systems: see the download page.
- you can build Twelf from the source tarball. You will need MLton or sml/nj.
- you can make yourself an account on the wiki, and do the exercises on your User:<login> page (linked at the top after you log in).
