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 current version of Isabelle offers Isar as an alternative proof language
73 interface layer. The Isabelle/Isar system provides an interpreter for the
74 Isar formal proof language. The input may consist either of proper document
75 constructors, or improper auxiliary commands (for diagnostics, exploration
76 etc.). Proof texts consisting of proper elements only, admit a purely
77 static reading, thus being intelligible later without requiring dynamic
78 replay that is so typical for traditional proof scripts. Any of the
79 Isabelle/Isar commands may be executed in single-steps, so basically the
80 interpreter has a proof text 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. Isar is as generic as Isabelle, able to support a wide range of
93 object-logics. Currently, the end-user working environment is most complete
