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