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