\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 current version of Isabelle offers Isar as an alternative proof language

  interface layer.  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.  Isar 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.
