    3.12 +text {*
    3.13 +  Isabelle/Isar provides a simple document preparation system based on
    3.14 +  existing {PDF-\LaTeX} technology, with full support of hyper-links
    3.15 +  (both local references and URLs) and bookmarks.  Thus the results
    3.16 +  are equally well suited for WWW browsing and as printed copies.
    3.17 +
    3.18 +  \medskip Isabelle generates {\LaTeX} output as part of the run of a
    3.19 +  \emph{logic session} (see also \cite{isabelle-sys}).  Getting
    3.20 +  started with a working configuration for common situations is quite
    3.21 +  easy by using the Isabelle @{verbatim mkdir} and @{verbatim make}
    3.22 +  tools.  First invoke
    3.23 +\begin{ttbox}
    3.24 +  isatool mkdir Foo
    3.25 +\end{ttbox}
    3.26 +  to initialize a separate directory for session @{verbatim Foo} ---
    3.27 +  it is safe to experiment, since @{verbatim "isatool mkdir"} never
    3.28 +  overwrites existing files.  Ensure that @{verbatim "Foo/ROOT.ML"}
    3.29 +  holds ML commands to load all theories required for this session;
    3.30 +  furthermore @{verbatim "Foo/document/root.tex"} should include any
    3.31 +  special {\LaTeX} macro packages required for your document (the
    3.32 +  default is usually sufficient as a start).
    3.33 +
    3.34 +  The session is controlled by a separate @{verbatim IsaMakefile}
    3.35 +  (with crude source dependencies by default).  This file is located
    3.36 +  one level up from the @{verbatim Foo} directory location.  Now
    3.37 +  invoke
    3.38 +\begin{ttbox}
    3.39 +  isatool make Foo
    3.40 +\end{ttbox}
    3.41 +  to run the @{verbatim Foo} session, with browser information and
    3.42 +  document preparation enabled.  Unless any errors are reported by
    3.43 +  Isabelle or {\LaTeX}, the output will appear inside the directory
    3.44 +  @{verbatim ISABELLE_BROWSER_INFO}, as reported by the batch job in
    3.45 +  verbose mode.
    3.46 +
    3.47 +  \medskip You may also consider to tune the @{verbatim usedir}
    3.48 +  options in @{verbatim IsaMakefile}, for example to change the output
    3.49 +  format from @{verbatim pdf} to @{verbatim dvi}, or activate the
    3.50 +  @{verbatim "-D"} option to retain a second copy of the generated
    3.51 +  {\LaTeX} sources.
    3.52 +
    3.53 +  \medskip See \emph{The Isabelle System Manual} \cite{isabelle-sys}
    3.54 +  for further details on Isabelle logic sessions and theory
    3.55 +  presentation.  The Isabelle/HOL tutorial \cite{isabelle-hol-book}
    3.56 +  also covers theory presentation issues.

    3.76 +
    3.77 +  Apart from formal comments (see \secref{sec:comments}), markup
    3.78 +  commands provide a structured way to insert text into the document
    3.79 +  generated from a theory (see \cite{isabelle-sys} for more
    3.80 +  information on Isabelle's document preparation tools).

    3.87 +  \end{rail}
    3.88 +
    3.89 +  \begin{descr}
    3.90 +
    3.91 +  \item [@{command "chapter"}, @{command "section"}, @{command
    3.92 +  "subsection"}, and @{command "subsubsection"}] mark chapter and
    3.93 +  section headings.
    3.94 +
    3.95 +  \item [@{command "text"} and @{command "txt"}] specify paragraphs of
    3.96 +  plain text.
    3.97 +
    3.98 +  \item [@{command "text_raw"} and @{command "txt_raw"}] insert
    3.99 +  {\LaTeX} source into the output, without additional markup.  Thus
   3.100 +  the full range of document manipulations becomes available.
   3.101 +
   3.102 +  \end{descr}
   3.103 +
   3.104 +  The @{text "text"} argument of these markup commands (except for
   3.105 +  @{command "text_raw"}) may contain references to formal entities
   3.106 +  (``antiquotations'', see also \secref{sec:antiq}).  These are
   3.107 +  interpreted in the present theory context, or the named @{text
   3.108 +  "target"}.
   3.109 +
   3.110 +  Any of these markup elements corresponds to a {\LaTeX} command with
   3.111 +  the name prefixed by @{verbatim "\\isamarkup"}.  For the sectioning
   3.112 +  commands this is a plain macro with a single argument, e.g.\
   3.113 +  @{verbatim "\\isamarkupchapter{"}@{text "\<dots>"}@{verbatim "}"} for
   3.114 +  @{command "chapter"}.  The @{command "text"} markup results in a
   3.115 +  {\LaTeX} environment @{verbatim "\\begin{isamarkuptext}"} @{text
   3.116 +  "\<dots>"} @{verbatim "\\end{isamarkuptext}"}, while @{command "text_raw"}
   3.117 +  causes the text to be inserted directly into the {\LaTeX} source.
   3.118 +
   3.119 +  \medskip The proof markup commands closely resemble those for theory
   3.120 +  specifications, but have a different formal status and produce
   3.121 +  different {\LaTeX} macros.  Also note that the @{command_ref
   3.122 +  "header"} declaration (see \secref{sec:begin-thy}) admits to insert
   3.123 +  section markup just preceding the actual theory definition.

   3.150 +
   3.151 +  The text body of formal comments (see also \secref{sec:comments})
   3.152 +  may contain antiquotations of logical entities, such as theorems,
   3.153 +  terms and types, which are to be presented in the final output
   3.154 +  produced by the Isabelle document preparation system (see also
   3.155 +  \chref{ch:document-prep}).
   3.156 +
   3.157 +  Thus embedding of ``@{text "@{term [show_types] \"f x = a + x\"}"}''
   3.158 +  within a text block would cause
   3.159 +  \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} to appear in the final {\LaTeX} document.  Also note that theorem
   3.160 +  antiquotations may involve attributes as well.  For example,
   3.161 +  @{text "@{thm sym [no_vars]}"} would print the theorem's
   3.162 +  statement where all schematic variables have been replaced by fixed
   3.163 +  ones, which are easier to read.

   3.199 +
   3.200 +  \begin{descr}
   3.201 +  
   3.202 +  \item [@{text "@{theory A}"}] prints the name @{text "A"}, which is
   3.203 +  guaranteed to refer to a valid ancestor theory in the current
   3.204 +  context.
   3.205 +
   3.206 +  \item [@{text "@{thm a\<^sub>1 \<dots> a\<^sub>n}"}] prints theorems
   3.207 +  @{text "a\<^sub>1 \<dots> a\<^sub>n"}.  Note that attribute specifications
   3.208 +  may be included as well (see also \secref{sec:syn-att}); the
   3.209 +  @{attribute_ref no_vars} rule (see \secref{sec:misc-meth-att}) would
   3.210 +  be particularly useful to suppress printing of schematic variables.
   3.211 +
   3.212 +  \item [@{text "@{prop \<phi>}"}] prints a well-typed proposition @{text
   3.213 +  "\<phi>"}.
   3.214 +
   3.215 +  \item [@{text "@{term t}"}] prints a well-typed term @{text "t"}.
   3.216 +
   3.217 +  \item [@{text "@{const c}"}] prints a logical or syntactic constant
   3.218 +  @{text "c"}.
   3.219 +  
   3.220 +  \item [@{text "@{abbrev c x\<^sub>1 \<dots> x\<^sub>n}"}] prints a constant
   3.221 +  abbreviation @{text "c x\<^sub>1 \<dots> x\<^sub>n \<equiv> rhs"} as defined in
   3.222 +  the current context.
   3.223 +
   3.224 +  \item [@{text "@{typeof t}"}] prints the type of a well-typed term
   3.225 +  @{text "t"}.
   3.226 +
   3.227 +  \item [@{text "@{typ \<tau>}"}] prints a well-formed type @{text "\<tau>"}.
   3.228 +  
   3.229 +  \item [@{text "@{thm_style s a}"}] prints theorem @{text a},
   3.230 +  previously applying a style @{text s} to it (see below).
   3.231 +  
   3.232 +  \item [@{text "@{term_style s t}"}] prints a well-typed term @{text
   3.233 +  t} after applying a style @{text s} to it (see below).
   3.234 +
   3.235 +  \item [@{text "@{text s}"}] prints uninterpreted source text @{text
   3.236 +  s}.  This is particularly useful to print portions of text according
   3.237 +  to the Isabelle {\LaTeX} output style, without demanding
   3.238 +  well-formedness (e.g.\ small pieces of terms that should not be
   3.239 +  parsed or type-checked yet).
   3.240 +
   3.241 +  \item [@{text "@{goals}"}] prints the current \emph{dynamic} goal
   3.242 +  state.  This is mainly for support of tactic-emulation scripts
   3.243 +  within Isar --- presentation of goal states does not conform to
   3.244 +  actual human-readable proof documents.
   3.245 +
   3.246 +  Please do not include goal states into document output unless you
   3.247 +  really know what you are doing!
   3.248 +  
   3.249 +  \item [@{text "@{subgoals}"}] is similar to @{text "@{goals}"}, but
   3.250 +  does not print the main goal.
   3.251 +  
   3.252 +  \item [@{text "@{prf a\<^sub>1 \<dots> a\<^sub>n}"}] prints the (compact)
   3.253 +  proof terms corresponding to the theorems @{text "a\<^sub>1 \<dots>
   3.254 +  a\<^sub>n"}. Note that this requires proof terms to be switched on
   3.255 +  for the current object logic (see the ``Proof terms'' section of the
   3.256 +  Isabelle reference manual for information on how to do this).
   3.257 +  
   3.258 +  \item [@{text "@{full_prf a\<^sub>1 \<dots> a\<^sub>n}"}] is like @{text
   3.259 +  "@{prf a\<^sub>1 \<dots> a\<^sub>n}"}, but displays the full proof terms,
   3.260 +  i.e.\ also displays information omitted in the compact proof term,
   3.261 +  which is denoted by ``@{text _}'' placeholders there.
   3.262 +  
   3.263 +  \item [@{text "@{ML s}"}, @{text "@{ML_type s}"}, and @{text
   3.264 +  "@{ML_struct s}"}] check text @{text s} as ML value, type, and
   3.265 +  structure, respectively.  The source is displayed verbatim.
   3.266 +
   3.267 +  \end{descr}
   3.268 +
   3.269 +  \medskip The following standard styles for use with @{text
   3.270 +  thm_style} and @{text term_style} are available:
   3.271 +
   3.272 +  \begin{descr}
   3.273 +  
   3.274 +  \item [@{text lhs}] extracts the first argument of any application
   3.275 +  form with at least two arguments -- typically meta-level or
   3.276 +  object-level equality, or any other binary relation.
   3.277 +  
   3.278 +  \item [@{text rhs}] is like @{text lhs}, but extracts the second
   3.279 +  argument.
   3.280 +  
   3.281 +  \item [@{text "concl"}] extracts the conclusion @{text C} from a rule
   3.282 +  in Horn-clause normal form @{text "A\<^sub>1 \<Longrightarrow> \<dots> A\<^sub>n \<Longrightarrow> C"}.
   3.283 +  
   3.284 +  \item [@{text "prem1"}, \dots, @{text "prem9"}] extract premise
   3.285 +  number @{text "1, \<dots>, 9"}, respectively, from from a rule in
   3.286 +  Horn-clause normal form @{text "A\<^sub>1 \<Longrightarrow> \<dots> A\<^sub>n \<Longrightarrow> C"}
   3.287 +
   3.288 +  \end{descr}
   3.289 +
   3.290 +  \medskip
   3.291 +  The following options are available to tune the output.  Note that most of
   3.292 +  these coincide with ML flags of the same names (see also \cite{isabelle-ref}).
   3.293 +
   3.294 +  \begin{descr}
   3.295 +
   3.296 +  \item[@{text "show_types = bool"} and @{text "show_sorts = bool"}]

   3.298 +
   3.299 +  \item[@{text "show_structs = bool"}] controls printing of implicit
   3.300 +  structures.
   3.301 +
   3.302 +  \item[@{text "long_names = bool"}] forces names of types and
   3.303 +  constants etc.\ to be printed in their fully qualified internal
   3.304 +  form.
   3.305 +
   3.306 +  \item[@{text "short_names = bool"}] forces names of types and
   3.307 +  constants etc.\ to be printed unqualified.  Note that internalizing
   3.308 +  the output again in the current context may well yield a different
   3.309 +  result.
   3.310 +
   3.311 +  \item[@{text "unique_names = bool"}] determines whether the printed
   3.312 +  version of qualified names should be made sufficiently long to avoid
   3.313 +  overlap with names declared further back.  Set to @{text false} for
   3.314 +  more concise output.
   3.315 +
   3.316 +  \item[@{text "eta_contract = bool"}] prints terms in @{text

   3.319 +  \item[@{text "display = bool"}] indicates if the text is to be
   3.320 +  output as multi-line ``display material'', rather than a small piece
   3.321 +  of text without line breaks (which is the default).
   3.322 +
   3.323 +  \item[@{text "break = bool"}] controls line breaks in non-display
   3.324 +  material.
   3.325 +
   3.326 +  \item[@{text "quotes = bool"}] indicates if the output should be
   3.327 +  enclosed in double quotes.
   3.328 +
   3.329 +  \item[@{text "mode = name"}] adds @{text name} to the print mode to
   3.330 +  be used for presentation (see also \cite{isabelle-ref}).  Note that
   3.331 +  the standard setup for {\LaTeX} output is already present by
   3.332 +  default, including the modes @{text latex} and @{text xsymbols}.
   3.333 +
   3.334 +  \item[@{text "margin = nat"} and @{text "indent = nat"}] change the
   3.335 +  margin or indentation for pretty printing of display material.
   3.336 +
   3.337 +  \item[@{text "source = bool"}] prints the source text of the
   3.338 +  antiquotation arguments, rather than the actual value.  Note that
   3.339 +  this does not affect well-formedness checks of @{antiquotation
   3.340 +  "thm"}, @{antiquotation "term"}, etc. (only the @{antiquotation
   3.341 +  "text"} antiquotation admits arbitrary output).
   3.342 +
   3.343 +  \item[@{text "goals_limit = nat"}] determines the maximum number of
   3.344 +  goals to be printed.
   3.345 +
   3.346 +  \item[@{text "locale = name"}] specifies an alternative locale
   3.347 +  context used for evaluating and printing the subsequent argument.

   3.351 +  For boolean flags, ``@{text "name = true"}'' may be abbreviated as
   3.352 +  ``@{text name}''.  All of the above flags are disabled by default,
   3.353 +  unless changed from ML.
   3.354 +
   3.355 +  \medskip Note that antiquotations do not only spare the author from
   3.356 +  tedious typing of logical entities, but also achieve some degree of
   3.357 +  consistency-checking of informal explanations with formal
   3.358 +  developments: well-formedness of terms and types with respect to the
   3.359 +  current theory or proof context is ensured here.

   3.366 +  Each Isabelle/Isar command may be decorated by presentation tags:

   3.369 +  \begin{rail}
   3.370 +    tags: ( tag * )
   3.371 +    ;
   3.372 +    tag: '\%' (ident | string)
   3.373 +  \end{rail}
   3.374 +
   3.375 +  The tags @{text "theory"}, @{text "proof"}, @{text "ML"} are already
   3.376 +  pre-declared for certain classes of commands:
   3.377 +
   3.378 + \medskip
   3.379 +
   3.380 +  \begin{tabular}{ll}
   3.381 +    @{text "theory"} & theory begin/end \\
   3.382 +    @{text "proof"} & all proof commands \\
   3.383 +    @{text "ML"} & all commands involving ML code \\
   3.384 +  \end{tabular}
   3.385 +
   3.386 +  \medskip The Isabelle document preparation system (see also
   3.387 +  \cite{isabelle-sys}) allows tagged command regions to be presented
   3.388 +  specifically, e.g.\ to fold proof texts, or drop parts of the text
   3.389 +  completely.
   3.390 +
   3.391 +  For example ``@{command "by"}~@{text "%invisible auto"}'' would
   3.392 +  cause that piece of proof to be treated as @{text invisible} instead
   3.393 +  of @{text "proof"} (the default), which may be either show or hidden
   3.394 +  depending on the document setup.  In contrast, ``@{command
   3.395 +  "by"}~@{text "%visible auto"}'' would force this text to be shown
   3.396 +  invariably.
   3.397 +
   3.398 +  Explicit tag specifications within a proof apply to all subsequent
   3.399 +  commands of the same level of nesting.  For example, ``@{command
   3.400 +  "proof"}~@{text "%visible \<dots>"}~@{command "qed"}'' would force the
   3.401 +  whole sub-proof to be typeset as @{text visible} (unless some of its
   3.402 +  parts are tagged differently).
