Apologies for multiple copies] Subject: Proof General --- Version 3.3 release Announcing Proof General Version 3.3 A Generic Emacs interface for Interactive Proof Assistants http://www.proofgeneral.org contact: David Aspinall Proof General is a generic (X)Emacs interface for proof assistants. It can be instantiated for the proof assistant of your choice, and is supplied ready-customised for Isabelle, Coq, LEGO, and PhoX, and, experimentally, for HOL, Twelf, and ACL2. Proof General includes these features, amongst others: . Script management: proof assistant state reflected in editor . Toolbar and menus: commands for building and replaying proofs . Syntax highlighting of proof scripts and prover output; hiding proofs . Display of real logical symbols, greek letters, etc . Simplified communication: proof assistant verbosity hidden . Menu for jumping to theorems in a proof script . Provision to easily run proof assistant on a remote host . Works on any platform Emacs does, in window system or plain console Summary of changes since 3.2: . Visibility control for completed proofs . Dependency browsing/highlighting (currently Isabelle only) . Bug fixes . Compatibility improvements: XEmacs 21.4, Coq 7, Windows For details of changes since 3.2, see http://www.proofgeneral.org/fileshow.php?file=ProofGeneral-3.3%2FCHANGES For the latest user manual, see http://www.proofgeneral.org/doc Proof General needs a recent version of Emacs to run with, and it much prefers XEmacs to FSF GNU Emacs. Proof General 3.3 has been tested with XEmacs 21.4 and Emacs 20.7. (It may work back to XEmacs 20.4 and Emacs 20.2, though). Installing Proof General is easy. Why not give it a try? - David Aspinall September 2001.
