\isamarkupsection{Plain TTY interaction \label{sec:tool-tty}%
}
\isamarkuptrue%
%
\begin{isamarkuptext}%
The \indexdef{}{tool}{tty}\hypertarget{tool.tty}{\hyperlink{tool.tty}{\mbox{\isa{\isatt{tty}}}}} tool runs the Isabelle process interactively
  within a plain terminal session:
\begin{ttbox}
Usage: tty [OPTIONS]

  Options are:
    -l NAME      logic image name (default ISABELLE_LOGIC)
    -m MODE      add print mode for output
    -p NAME      line editor program name (default ISABELLE_LINE_EDITOR)

  Run Isabelle process with plain tty interaction, and optional line editor.
\end{ttbox}

  The \verb|-l| option specifies the logic image.  The
  \verb|-m| option specifies additional print modes.  The The
  \verb|-p| option specifies an alternative line editor (such
  as the \indexdef{}{executable}{rlwrap}\hypertarget{executable.rlwrap}{\hyperlink{executable.rlwrap}{\mbox{\isa{\isatt{rlwrap}}}}} wrapper for GNU readline); the
  fall-back is to use raw standard input.

  Regular interaction is via the standard Isabelle/Isar toplevel loop.
  The Isar command \hyperlink{command.exit}{\mbox{\isa{\isacommand{exit}}}} drops out into the raw ML system,
  which is occasionally useful for low-level debugging.  Invoking \verb|Isar.loop|~\verb|();| in ML will return to the Isar toplevel.%

\isamarkupsection{Proof General / Emacs%
}
\isamarkuptrue%
%
\begin{isamarkuptext}%
The \indexdef{}{tool}{emacs}\hypertarget{tool.emacs}{\hyperlink{tool.emacs}{\mbox{\isa{\isatt{emacs}}}}} tool invokes a version of Emacs and Proof
  General within the regular Isabelle settings environment
  (\secref{sec:settings}).  This is more robust than starting Emacs
  separately, loading the Proof General lisp files, and then
  attempting to start Isabelle with dynamic \hyperlink{setting.PATH}{\mbox{\isa{\isatt{PATH}}}} lookup
  etc.

  The actual interface script is part of the Proof General
  distribution~\cite{proofgeneral}; its usage depends on the
  particular version.  There are some options available, such as
  \verb|-l| for passing the logic image to be used by default,
  or \verb|-m| to tune the standard print mode.  The following
  Isabelle settings are particularly important for Proof General:

  \begin{description}

  \item[\indexdef{}{setting}{PROOFGENERAL\_HOME}\hypertarget{setting.PROOFGENERAL-HOME}{\hyperlink{setting.PROOFGENERAL-HOME}{\mbox{\isa{\isatt{PROOFGENERAL{\isacharunderscore}HOME}}}}}] points to the main
  installation directory of the Proof General distribution.  The
  default settings try to locate this in a number of standard places,
  notably \verb|$ISABELLE_HOME/contrib/ProofGeneral|.

  \item[\indexdef{}{setting}{PROOFGENERAL\_OPTIONS}\hypertarget{setting.PROOFGENERAL-OPTIONS}{\hyperlink{setting.PROOFGENERAL-OPTIONS}{\mbox{\isa{\isatt{PROOFGENERAL{\isacharunderscore}OPTIONS}}}}}] is implicitly prefixed to
  the command line of any invocation of the Proof General \verb|interface| script.

  \item[\indexdef{}{setting}{XSYMBOL\_INSTALLFONTS}\hypertarget{setting.XSYMBOL-INSTALLFONTS}{\hyperlink{setting.XSYMBOL-INSTALLFONTS}{\mbox{\isa{\isatt{XSYMBOL{\isacharunderscore}INSTALLFONTS}}}}}] may contain a small shell
  script to install the X11 fonts required for the X-Symbols mode of
  Proof General.  This is only relevant if the X11 display server runs
  on a different machine than the Emacs application, with a different
  file-system view on the Proof General installation.  Under most
  circumstances Proof General is able to refer to the font files that
  are part of its distribution.
