40 \emph{Intelligible semi-automated reasoning} (\emph{Isar}) is a generic
41 approach to readable formal proof documents. It sets out to bridge the
42 semantic gap between any internal notions of proof based on primitive
43 inferences and tactics, and an appropriate level of abstraction for
44 user-level work. The Isar formal proof language has been designed to
45 satisfy quite contradictory requirements, being both ``declarative'' and
46 immediately ``executable'', by virtue of the \emph{Isar/VM} interpreter.
48 The current version of Isabelle offers Isar as an alternative proof language
49 interface layer, beyond traditional tactic scripts. The Isabelle/Isar
50 system provides an interpreter for the Isar formal proof document language.
51 Isabelle/Isar input may consist either of \emph{proper document
52 constructors}, or \emph{improper auxiliary commands} (for diagnostics,
53 exploration etc.). Proof texts consisting of proper document constructors
54 only, admit a purely static reading, thus being intelligible later without
55 requiring dynamic replay that is so typical for traditional proof scripts.
56 Any of the Isabelle/Isar commands may be executed in single-steps, so
57 basically the interpreter has a proof text debugger already built-in.
59 Employing the Isar instantiation of \emph{Proof~General}, the generic Emacs
60 interface for interactive proof assistants of LFCS Edinburgh, we arrive at a
61 reasonable environment for \emph{live document editing}. Thus proof texts
62 may be developed incrementally by issuing proper document constructors,
63 including forward and backward tracing of partial documents; intermediate
64 states may be inspected by diagnostic commands.
66 The Isar subsystem is tightly integrated into the Isabelle/Pure meta-logic
67 implementation. Theories, theorems, proof procedures etc.\ may be used
68 interchangeably between Isabelle-classic proof scripts and Isabelle/Isar
69 documents. Isar is as generic as Isabelle, able to support a wide range of
70 object-logics. The current end-user setup is mainly for Isabelle/HOL.
