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