The Isabelle System Distribution

See the NEWS file in the distribution for details on user-relevant changes. The ANNOUNCE file recounts notable changes for the latest official release.

The core of Isabelle is subject to a 3-clause BSD license, but add-on components have their own license schemes (similar to a Linux distribution).

Installation

Isabelle works on the three main platform families: Linux, Windows, and macOS. The application bundles from the Isabelle web page include sources, documentation, and add-on tools for all supported platforms.

Some technical background information may be found in the Isabelle System Manual (directory doc).

User interface

Isabelle/jEdit is an advanced Prover IDE based on jEdit and Isabelle/Scala. It is the main example application of the Isabelle/PIDE framework, and the default user interface of Isabelle. It provides a metaphor of continuous proof checking of a versioned collection of theory sources, with instantaneous feedback in real-time and rich semantic markup associated with the formal text.
