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