\begin{isamarkuptext}%
Isabelle/Isar provides a simple document preparation system
based on regular {PDF-\LaTeX} technology, with full support for
hyper-links and bookmarks. Thus the results are well suited for WWW
browsing and as printed copies.
\medskip Isabelle generates {\LaTeX} output while running a
\emph{logic session} (see also \cite{isabelle-sys}). Getting
started with a working configuration for common situations is quite
easy by using the Isabelle \verb|mkdir| and \verb|make|
tools. First invoke
\begin{ttbox}
isabelle mkdir Foo
\end{ttbox}
to initialize a separate directory for session \verb|Foo| (it
is safe to experiment, since \verb|isabelle mkdir| never
overwrites existing files). Ensure that \verb|Foo/ROOT.ML|
holds ML commands to load all theories required for this session;
furthermore \verb|Foo/document/root.tex| should include any
special {\LaTeX} macro packages required for your document (the
default is usually sufficient as a start).
The session is controlled by a separate \verb|IsaMakefile|
(with crude source dependencies by default). This file is located
one level up from the \verb|Foo| directory location. Now
invoke
\begin{ttbox}
isabelle make Foo
\end{ttbox}
to run the \verb|Foo| session, with browser information and
document preparation enabled. Unless any errors are reported by
Isabelle or {\LaTeX}, the output will appear inside the directory
defined by the \verb|ISABELLE_BROWSER_INFO| setting (as
reported by the batch job in verbose mode).
\medskip You may also consider to tune the \verb|usedir|
options in \verb|IsaMakefile|, for example to switch the output
format between \verb|pdf| and \verb|dvi|, or activate the
\verb|-D| option to retain a second copy of the generated
{\LaTeX} sources (for manual inspection or separate runs of
\hyperlink{executable.latex}{\mbox{\isa{\isatt{latex}}}}).
\medskip See \emph{The Isabelle System Manual} \cite{isabelle-sys}
for further details on Isabelle logic sessions and theory
presentation. The Isabelle/HOL tutorial \cite{isabelle-hol-book}
also covers theory presentation to some extent.%

Markup commands provide a structured way to insert text into the
document generated from a theory. Each markup command takes a
single \hyperlink{syntax.text}{\mbox{\isa{text}}} argument, which is passed as argument to a
corresponding {\LaTeX} macro. The default macros provided by
\verb|~~/lib/texinputs/isabelle.sty| can be redefined according
to the needs of the underlying document and {\LaTeX} styles.
Note that formal comments (\secref{sec:comments}) are similar to
markup commands, but have a different status within Isabelle/Isar
syntax.

\begin{description}
\item \hyperlink{command.header}{\mbox{\isa{\isacommand{header}}}} provides plain text markup just preceding
the formal beginning of a theory. The corresponding {\LaTeX} macro
is \verb|\isamarkupheader|, which acts like \hyperlink{command.section}{\mbox{\isa{\isacommand{section}}}} by default.
\item \hyperlink{command.chapter}{\mbox{\isa{\isacommand{chapter}}}}, \hyperlink{command.section}{\mbox{\isa{\isacommand{section}}}}, \hyperlink{command.subsection}{\mbox{\isa{\isacommand{subsection}}}},
and \hyperlink{command.subsubsection}{\mbox{\isa{\isacommand{subsubsection}}}} mark chapter and section headings
within the main theory body or local theory targets. The
corresponding {\LaTeX} macros are \verb|\isamarkupchapter|,
\verb|\isamarkupsection|, \verb|\isamarkupsubsection| etc.
\item \hyperlink{command.sect}{\mbox{\isa{\isacommand{sect}}}}, \hyperlink{command.subsect}{\mbox{\isa{\isacommand{subsect}}}}, and \hyperlink{command.subsubsect}{\mbox{\isa{\isacommand{subsubsect}}}}
mark section headings within proofs. The corresponding {\LaTeX}
macros are \verb|\isamarkupsect|, \verb|\isamarkupsubsect| etc.
\item \hyperlink{command.text}{\mbox{\isa{\isacommand{text}}}} and \hyperlink{command.txt}{\mbox{\isa{\isacommand{txt}}}} specify paragraphs of plain
text. This corresponds to a {\LaTeX} environment \verb|\begin{isamarkuptext}| \isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{5C3C646F74733E}{\isasymdots}}{\isaliteral{22}{\isachardoublequote}}} \verb|\end{isamarkuptext}| etc.
\item \hyperlink{command.text-raw}{\mbox{\isa{\isacommand{text{\isaliteral{5F}{\isacharunderscore}}raw}}}} and \hyperlink{command.txt-raw}{\mbox{\isa{\isacommand{txt{\isaliteral{5F}{\isacharunderscore}}raw}}}} insert {\LaTeX}
source into the output, without additional markup. Thus the full
range of document manipulations becomes available, at the risk of
messing up document output.
\end{description}
Except for \hyperlink{command.text-raw}{\mbox{\isa{\isacommand{text{\isaliteral{5F}{\isacharunderscore}}raw}}}} and \hyperlink{command.txt-raw}{\mbox{\isa{\isacommand{txt{\isaliteral{5F}{\isacharunderscore}}raw}}}}, the text
passed to any of the above markup commands may refer to formal
entities via \emph{document antiquotations}, see also
\secref{sec:antiq}. These are interpreted in the present theory or
proof context, or the named \isa{{\isaliteral{22}{\isachardoublequote}}target{\isaliteral{22}{\isachardoublequote}}}.
\medskip The proof markup commands closely resemble those for theory
specifications, but have a different formal status and produce
different {\LaTeX} macros. The default definitions coincide for
analogous commands such as \hyperlink{command.section}{\mbox{\isa{\isacommand{section}}}} and \hyperlink{command.sect}{\mbox{\isa{\isacommand{sect}}}}.%

The overall content of an Isabelle/Isar theory may alternate between
formal and informal text. The main body consists of formal
specification and proof commands, interspersed with markup commands
(\secref{sec:markup}) or document comments (\secref{sec:comments}).
The argument of markup commands quotes informal text to be printed
in the resulting document, but may again refer to formal entities
via \emph{document antiquotations}.
For example, embedding of ``\isa{{\isaliteral{40}{\isacharat}}{\isaliteral{7B}{\isacharbraceleft}}term\ {\isaliteral{5B}{\isacharbrackleft}}show{\isaliteral{5F}{\isacharunderscore}}types{\isaliteral{5D}{\isacharbrackright}}\ {\isaliteral{22}{\isachardoublequote}}f\ x\ {\isaliteral{3D}{\isacharequal}}\ a\ {\isaliteral{2B}{\isacharplus}}\ x{\isaliteral{22}{\isachardoublequote}}{\isaliteral{7D}{\isacharbraceright}}}''
within a text block makes
\isa{{\isacharparenleft}f{\isasymColon}{\isacharprime}a\ {\isasymRightarrow}\ {\isacharprime}a{\isacharparenright}\ {\isacharparenleft}x{\isasymColon}{\isacharprime}a{\isacharparenright}\ {\isacharequal}\ {\isacharparenleft}a{\isasymColon}{\isacharprime}a{\isacharparenright}\ {\isacharplus}\ x} appear in the final {\LaTeX} document.
Antiquotations usually spare the author tedious typing of logical
entities in full detail. Even more importantly, some degree of
consistency-checking between the main body of formal text and its
informal explanation is achieved, since terms and types appearing in
antiquotations are checked within the current theory or proof
context.

The antiquotations \isa{thm}, \isa{prop} and \isa{term} admit an extra \emph{style} specification to modify the

\begin{isamarkuptext}%
The following options are available to tune the printed output
of antiquotations. Note that many of these coincide with global ML
flags of the same names.
\begin{description}
\item \indexdef{}{antiquotation option}{show\_types}\hypertarget{antiquotation option.show-types}{\hyperlink{antiquotation option.show-types}{\mbox{\isa{show{\isaliteral{5F}{\isacharunderscore}}types}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} and

printing of explicit type and sort constraints.
\item \indexdef{}{antiquotation option}{show\_structs}\hypertarget{antiquotation option.show-structs}{\hyperlink{antiquotation option.show-structs}{\mbox{\isa{show{\isaliteral{5F}{\isacharunderscore}}structs}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}}
controls printing of implicit structures.
\item \indexdef{}{antiquotation option}{show\_abbrevs}\hypertarget{antiquotation option.show-abbrevs}{\hyperlink{antiquotation option.show-abbrevs}{\mbox{\isa{show{\isaliteral{5F}{\isacharunderscore}}abbrevs}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}}
controls folding of abbreviations.
\item \indexdef{}{antiquotation option}{names\_long}\hypertarget{antiquotation option.names-long}{\hyperlink{antiquotation option.names-long}{\mbox{\isa{names{\isaliteral{5F}{\isacharunderscore}}long}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} forces
names of types and constants etc.\ to be printed in their fully
qualified internal form.
\item \indexdef{}{antiquotation option}{names\_short}\hypertarget{antiquotation option.names-short}{\hyperlink{antiquotation option.names-short}{\mbox{\isa{names{\isaliteral{5F}{\isacharunderscore}}short}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}}
forces names of types and constants etc.\ to be printed unqualified.
Note that internalizing the output again in the current context may
well yield a different result.
\item \indexdef{}{antiquotation option}{names\_unique}\hypertarget{antiquotation option.names-unique}{\hyperlink{antiquotation option.names-unique}{\mbox{\isa{names{\isaliteral{5F}{\isacharunderscore}}unique}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}}
determines whether the printed version of qualified names should be
made sufficiently long to avoid overlap with names declared further
back. Set to \isa{false} for more concise output.
\item \indexdef{}{antiquotation option}{eta\_contract}\hypertarget{antiquotation option.eta-contract}{\hyperlink{antiquotation option.eta-contract}{\mbox{\isa{eta{\isaliteral{5F}{\isacharunderscore}}contract}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}}
prints terms in \isa{{\isaliteral{5C3C6574613E}{\isasymeta}}}-contracted form.
\item \indexdef{}{antiquotation option}{display}\hypertarget{antiquotation option.display}{\hyperlink{antiquotation option.display}{\mbox{\isa{display}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} indicates
if the text is to be output as multi-line ``display material'',
rather than a small piece of text without line breaks (which is the
default).
In this mode the embedded entities are printed in the same style as
the main theory text.
\item \indexdef{}{antiquotation option}{break}\hypertarget{antiquotation option.break}{\hyperlink{antiquotation option.break}{\mbox{\isa{break}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} controls
line breaks in non-display material.
\item \indexdef{}{antiquotation option}{quotes}\hypertarget{antiquotation option.quotes}{\hyperlink{antiquotation option.quotes}{\mbox{\isa{quotes}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} indicates
if the output should be enclosed in double quotes.
\item \indexdef{}{antiquotation option}{mode}\hypertarget{antiquotation option.mode}{\hyperlink{antiquotation option.mode}{\mbox{\isa{mode}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ name{\isaliteral{22}{\isachardoublequote}}} adds \isa{name} to the print mode to be used for presentation. Note that the
standard setup for {\LaTeX} output is already present by default,
including the modes \isa{latex} and \isa{xsymbols}.
\item \indexdef{}{antiquotation option}{margin}\hypertarget{antiquotation option.margin}{\hyperlink{antiquotation option.margin}{\mbox{\isa{margin}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ nat{\isaliteral{22}{\isachardoublequote}}} and

or indentation for pretty printing of display material.
\item \indexdef{}{antiquotation option}{goals\_limit}\hypertarget{antiquotation option.goals-limit}{\hyperlink{antiquotation option.goals-limit}{\mbox{\isa{goals{\isaliteral{5F}{\isacharunderscore}}limit}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ nat{\isaliteral{22}{\isachardoublequote}}}
determines the maximum number of goals to be printed (for goal-based
antiquotation).
\item \indexdef{}{antiquotation option}{source}\hypertarget{antiquotation option.source}{\hyperlink{antiquotation option.source}{\mbox{\isa{source}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ bool{\isaliteral{22}{\isachardoublequote}}} prints the
original source text of the antiquotation arguments, rather than its
internal representation. Note that formal checking of
\hyperlink{antiquotation.thm}{\mbox{\isa{thm}}}, \hyperlink{antiquotation.term}{\mbox{\isa{term}}}, etc. is still
enabled; use the \hyperlink{antiquotation.text}{\mbox{\isa{text}}} antiquotation for unchecked
output.
Regular \isa{{\isaliteral{22}{\isachardoublequote}}term{\isaliteral{22}{\isachardoublequote}}} and \isa{{\isaliteral{22}{\isachardoublequote}}typ{\isaliteral{22}{\isachardoublequote}}} antiquotations with \isa{{\isaliteral{22}{\isachardoublequote}}source\ {\isaliteral{3D}{\isacharequal}}\ false{\isaliteral{22}{\isachardoublequote}}} involve a full round-trip from the original source
to an internalized logical entity back to a source form, according
to the syntax of the current context. Thus the printed output is
not under direct control of the author, it may even fluctuate a bit
as the underlying theory is changed later on.
In contrast, \hyperlink{antiquotation option.source}{\mbox{\isa{source}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3D}{\isacharequal}}\ true{\isaliteral{22}{\isachardoublequote}}}
admits direct printing of the given source text, with the desirable
well-formedness check in the background, but without modification of
the printed text.
\end{description}
For boolean flags, ``\isa{{\isaliteral{22}{\isachardoublequote}}name\ {\isaliteral{3D}{\isacharequal}}\ true{\isaliteral{22}{\isachardoublequote}}}'' may be abbreviated as
``\isa{name}''. All of the above flags are disabled by default,
unless changed from ML, say in the \verb|ROOT.ML| of the
logic session.%

\isamarkupsection{Markup via command tags \label{sec:tags}%
}
\isamarkuptrue%
%
\begin{isamarkuptext}%
Each Isabelle/Isar command may be decorated by additional
presentation tags, to indicate some modification in the way it is
printed in the document.
\begin{railoutput}
\rail@begin{2}{\indexdef{}{syntax}{tags}\hypertarget{syntax.tags}{\hyperlink{syntax.tags}{\mbox{\isa{tags}}}}}

\rail@nextbar{1}
\rail@nont{\hyperlink{syntax.string}{\mbox{\isa{string}}}}[]
\rail@endbar
\rail@end
\end{railoutput}
Some tags are pre-declared for certain classes of commands, serving
as default markup if no tags are given in the text:
\medskip
\begin{tabular}{ll}
\isa{{\isaliteral{22}{\isachardoublequote}}theory{\isaliteral{22}{\isachardoublequote}}} & theory begin/end \\
\isa{{\isaliteral{22}{\isachardoublequote}}proof{\isaliteral{22}{\isachardoublequote}}} & all proof commands \\
\isa{{\isaliteral{22}{\isachardoublequote}}ML{\isaliteral{22}{\isachardoublequote}}} & all commands involving ML code \\
\end{tabular}
\medskip The Isabelle document preparation system
\cite{isabelle-sys} allows tagged command regions to be presented
specifically, e.g.\ to fold proof texts, or drop parts of the text
completely.
For example ``\hyperlink{command.by}{\mbox{\isa{\isacommand{by}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{25}{\isacharpercent}}invisible\ auto{\isaliteral{22}{\isachardoublequote}}}'' causes
that piece of proof to be treated as \isa{invisible} instead of
\isa{{\isaliteral{22}{\isachardoublequote}}proof{\isaliteral{22}{\isachardoublequote}}} (the default), which may be shown or hidden
depending on the document setup. In contrast, ``\hyperlink{command.by}{\mbox{\isa{\isacommand{by}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{25}{\isacharpercent}}visible\ auto{\isaliteral{22}{\isachardoublequote}}}'' forces this text to be shown
invariably.
Explicit tag specifications within a proof apply to all subsequent
commands of the same level of nesting. For example, ``\hyperlink{command.proof}{\mbox{\isa{\isacommand{proof}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{25}{\isacharpercent}}visible\ {\isaliteral{5C3C646F74733E}{\isasymdots}}{\isaliteral{22}{\isachardoublequote}}}~\hyperlink{command.qed}{\mbox{\isa{\isacommand{qed}}}}'' forces the whole
sub-proof to be typeset as \isa{visible} (unless some of its parts
are tagged differently).
\medskip Command tags merely produce certain markup environments for
type-setting. The meaning of these is determined by {\LaTeX}
macros, as defined in \verb|~~/lib/texinputs/isabelle.sty| or
by the document author. The Isabelle document preparation tools
also provide some high-level options to specify the meaning of
arbitrary tags to ``keep'', ``drop'', or ``fold'' the corresponding
parts of the text. Logic sessions may also specify ``document
versions'', where given tags are interpreted in some particular way.
Again see \cite{isabelle-sys} for further details.%

The lexical syntax of \isa{{\isaliteral{22}{\isachardoublequote}}identifier{\isaliteral{22}{\isachardoublequote}}} coincides with that of
\hyperlink{syntax.ident}{\mbox{\isa{ident}}} in regular Isabelle syntax, but \isa{string} uses
single quotes instead of double quotes of the standard \hyperlink{syntax.string}{\mbox{\isa{string}}} category, to avoid extra escapes.
Each \isa{rule} defines a formal language (with optional name),
using a notation that is similar to EBNF or regular expressions with
recursion. The meaning and visual appearance of these rail language
elements is illustrated by the following representative examples.
