59 \emph{Intelligible semi-automated reasoning} (\emph{Isar}) is a generic
60 approach to readable formal proof documents. It sets out to bridge the
61 semantic gap between any internal notions of proof based on primitive
62 inferences and tactics, and an appropriate level of abstraction for
63 user-level work. The Isar formal proof language has been designed to
64 satisfy quite contradictory requirements, being both ``declarative'' and
65 immediately ``executable'', by virtue of the \emph{Isar/VM} interpreter.
67 The current version of Isabelle offers Isar as an alternative proof language
68 interface layer. The Isabelle/Isar system provides an interpreter for the
69 Isar formal proof language. The input may consist either of proper document
70 constructors, or improper auxiliary commands (for diagnostics, exploration
71 etc.). Proof texts consisting of proper elements only, admit a purely
72 static reading, thus being intelligible later without requiring dynamic
73 replay that is so typical for traditional proof scripts. Any of the
74 Isabelle/Isar commands may be executed in single-steps, so basically the
75 interpreter has a proof text debugger already built-in.
77 Employing the Isar instantiation of \emph{Proof~General}, a generic Emacs
78 interface for interactive proof assistants, we arrive at a reasonable
79 environment for \emph{live document editing}. Thus proof texts may be
80 developed incrementally by issuing proof commands, including forward and
81 backward tracing of partial documents; intermediate states may be inspected
82 by diagnostic commands.
84 The Isar subsystem is tightly integrated into the Isabelle/Pure meta-logic
85 implementation. Theories, theorems, proof procedures etc.\ may be used
86 interchangeably between classic Isabelle proof scripts and Isabelle/Isar
87 documents. Isar is as generic as Isabelle, able to support a wide range of
88 object-logics. Currently, the end-user working environment is most complete
