This is the internal repository version of Isabelle. See the NEWS file in the distribution for details on user-relevant changes.
Isabelle requires a regular Unix platform (e.g. GNU Linux) with the following additional software:
Binary packages are available for Isabelle/HOL and ZF for several platforms from the Isabelle web page. The system may be easily built from scratch as well, taking the traditional tar.gz source distribution. See file INSTALL as distributed with Isabelle for more information.
Further background information may be found in the Isabelle System Manual, distributed with the sources (directory doc).
The canonical Isabelle user interface is Proof General by David Aspinall and others. It is a generic (X)Emacs interface for proof assistants, including Isabelle (both for the classic and Isar version). Proof General is suitable for use by pacifists and Emacs militants alike. Its most prominent feature is script management, providing a metaphor of live proof script editing. Proof General has recently gained a rather large following of both beginning and expert users of Isabelle.
Proof General is distributed together with the XEmacs X-Symbol package, which provides a nice way to get proper mathematical symbols displayed on screen.
The Isabelle home page may be accessed both from Cambridge and Munich:
The electronic mailing list isabelle-users@cl.cam.ac.uk provides a forum for Isabelle users to discuss problems and exchange information. To join, send a message to isabelle-users-request@cl.cam.ac.uk.
