Isabelle provides several ways to present the outcome of formal |
|
11 |
developments, including WWW-based browsable libraries or actual |
|
12 |
printable documents. Presentation is centered around the concept of |
|
13 |
\emph{logic sessions}. The global session structure is that of a |
|
14 |
tree, with Isabelle Pure at its root, further object-logics derived |
|
15 |
(e.g.\ HOLCF from HOL, and HOL from Pure), and application sessions |
|
16 |
in leaf positions (usually without a separate image). |
|
17 |
||
18 |
The Isabelle tools @{tool_ref mkdir} and @{tool_ref make} provide |
|
19 |
the primary means for managing Isabelle sessions, including proper |
|
20 |
setup for presentation. Here the @{tool_ref usedir} tool takes care |
|
21 |
to let @{executable_ref "isabelle-process"} process run any |
|
22 |
additional stages required for document preparation, notably the |
|
23 |
tools @{tool_ref document} and @{tool_ref latex}. The complete tool |
|
24 |
chain for managing batch-mode Isabelle sessions is illustrated in |
|
25 |
\figref{fig:session-tools}. |

|
62 |

63 |
As a side-effect of running a logic sessions, Isabelle is able to |
|
64 |
generate theory browsing information, including HTML documents that |
|
65 |
show a theory's definition, the theorems proved in its ML file and |
|
66 |
the relationship with its ancestors and descendants. Besides the |
|
67 |
HTML file that is generated for every theory, Isabelle stores links |
|
68 |
to all theories in an index file. These indexes are linked with |
|
69 |
other indexes to represent the overall tree structure of logic |
|
70 |
sessions. |
|
71 |
||
72 |
Isabelle also generates graph files that represent the theory |
|
73 |
hierarchy of a logic. There is a graph browser Java applet embedded |
|
74 |
in the generated HTML pages, and also a stand-alone application that |
|
75 |
allows browsing theory graphs without having to start a WWW client |
|
76 |
first. The latter version also includes features such as generating |
|
77 |
Postscript files, which are not available in the applet version. |
|
78 |
See \secref{sec:browse} for further information. |
|
79 |
||
80 |
\medskip |
|
81 |
||
82 |
The easiest way to let Isabelle generate theory browsing information |
|
83 |
for existing sessions is to append ``@{verbatim "-i true"}'' to the |
|
84 |
@{setting_ref ISABELLE_USEDIR_OPTIONS} before invoking @{verbatim |
|

85 |
isabelle} @{tool make} (or @{"file" "$ISABELLE_HOME/build"}). For |
28221 | 86 |
example, add something like this to your Isabelle settings file |
87 |
||
88 |
\begin{ttbox} |
|
89 |
ISABELLE_USEDIR_OPTIONS="-i true" |
|
90 |
\end{ttbox} |
|
91 |
||
28238 | 92 |
and then change into the @{"file" "~~/src/FOL"} directory and run |

@{verbatim isabelle} @{tool make}, or even @{verbatim isabelle} @{tool |
28238 | 94 |
make}~@{verbatim all}. The presentation output will appear in |
95 |
@{verbatim "ISABELLE_BROWSER_INFO/FOL"}, which usually refers to |

@{verbatim "~/.isabelle/browser_info/FOL"}. Note that option |
28221 | 97 |
@{verbatim "-v true"} will make the internal runs of @{tool usedir} |
98 |
more explicit about such details. |
|
99 |
||
28238 | 100 |
Many standard Isabelle sessions (such as @{"file" "~~/src/HOL/ex"}) |
101 |
also provide actual printable documents. These are prepared |
|
28221 | 102 |
automatically as well if enabled like this, using the @{verbatim |
103 |
"-d"} option |
|
104 |
\begin{ttbox} |
|
105 |
ISABELLE_USEDIR_OPTIONS="-i true -d dvi" |
|
106 |
\end{ttbox} |
|
107 |
Enabling options @{verbatim "-i"} and @{verbatim "-d"} |
|
28225 | 108 |
simultaneously as shown above causes an appropriate ``document'' |
28221 | 109 |
link to be included in the HTML index. Documents (or raw document |
110 |
sources) may be generated independently of browser information as |
|
111 |
well, see \secref{sec:tool-document} for further details. |
|
112 |
||
113 |
\bigskip The theory browsing information is stored in a |
|
114 |
sub-directory directory determined by the @{setting_ref |
|
115 |
ISABELLE_BROWSER_INFO} setting plus a prefix corresponding to the |
|
116 |
session identifier (according to the tree structure of sub-sessions |
|
117 |
by default). A complete WWW view of all standard object-logics and |
|
28225 | 118 |
examples of the Isabelle distribution is available at the usual |
119 |
Isabelle sites: |

invoked in an appropriate @{verbatim IsaMakefile}, via the Isabelle |

The Isabelle graph browser is a general tool for visualizing |

167 |
dependency graphs. Certain nodes of the graph (i.e.~theories) can |
|
168 |
be grouped together in ``directories'', whose contents may be |
|
169 |
hidden, thus enabling the user to collapse irrelevant portions of |
|
170 |
information. The browser is written in Java, it can be used both as |
|

a stand-alone application and as an applet. Note that the option |

We describe the usage of the directory browser and the meaning of |
|
226 |
the different items in the browser window. |
|
227 |
||
228 |
\begin{itemize} |
|
229 |
||
230 |
\item A red arrow before a directory name indicates that the |
|
231 |
directory is currently ``folded'', i.e.~the nodes in this directory |
|
232 |
are collapsed to one single node. In the right sub-window, the names |
|
233 |
of nodes corresponding to folded directories are enclosed in square |
|
234 |
brackets and displayed in red color. |
|
235 |
||
236 |
\item A green downward arrow before a directory name indicates that |
|
237 |
the directory is currently ``unfolded''. It can be folded by |
|
238 |
clicking on the directory name. Clicking on the name for a second |
|
239 |
time unfolds the directory again. Alternatively, a directory can |
|
240 |
also be unfolded by clicking on the corresponding node in the right |
|
241 |
sub-window. |
|
242 |
||
243 |
\item Blue arrows stand before ordinary node names. When clicking on |
|
244 |
such a name (i.e.\ that of a theory), the graph display window |
|
245 |
focuses to the corresponding node. Double clicking invokes a text |
|
246 |
viewer window in which the contents of the theory file are |
|
247 |
displayed. |

When pointing on an ordinary node, an upward and a downward arrow is |

shown. Initially, both of these arrows are green. Clicking on the |

258 |
upward or downward arrow collapses all predecessor or successor |
|
259 |
nodes, respectively. The arrow's color then changes to red, |
|
260 |
indicating that the predecessor or successor nodes are currently |
|
261 |
collapsed. The node corresponding to the collapsed nodes has the |
|
262 |
name ``@{verbatim "[....]"}''. To uncollapse the nodes again, simply |
|
263 |
click on the red arrow or on the node with the name ``@{verbatim |
|
264 |
"[....]"}''. Similar to the directory browser, the contents of |
|
265 |
theory files can be displayed by double clicking on the |

266 |
corresponding node. |

The meaning of the items in a vertex description is as follows: |
|
308 |
||
309 |
\begin{description} |
|
310 |
||
311 |
\item[@{text vertex_name}] The name of the vertex. |
|
312 |
||
313 |
\item[@{text vertex_ID}] The vertex identifier. Note that there may |
|
314 |
be several vertices with equal names, whereas identifiers must be |
|
315 |
unique. |
|
316 |
||
317 |
\item[@{text dir_name}] The name of the ``directory'' the vertex |
|
318 |
should be placed in. A ``@{verbatim "+"}'' sign after @{text |
|
319 |
dir_name} indicates that the nodes in the directory are initially |
|
320 |
visible. Directories are initially invisible by default. |
|
321 |
||
322 |
\item[@{text path}] The path of the corresponding theory file. This |
|
323 |
is specified relatively to the path of the graph definition file. |
|
324 |
||
325 |
\item[List of successor/predecessor nodes] A ``@{verbatim "<"}'' |
|
326 |
sign before the list means that successor nodes are listed, a |
|
327 |
``@{verbatim ">"}'' sign means that predecessor nodes are listed. If |
|
328 |
neither ``@{verbatim "<"}'' nor ``@{verbatim ">"}'' is found, the |
|
329 |
browser assumes that successor nodes are listed. |

The @{tool_def mkdir} utility prepares Isabelle session source |
|
340 |
directories, including a sensible default setup of @{verbatim |
|
341 |
IsaMakefile}, @{verbatim ROOT.ML}, and a @{verbatim document} |
|
342 |
directory with a minimal @{verbatim root.tex} that is sufficient to |
|
343 |
print all theories of the session (in the order of appearance); see |

The @{tool mkdir} tool is conservative in the sense that any |

362 |
existing @{verbatim IsaMakefile} etc.\ is left unchanged. Thus it |
|
363 |
is safe to invoke it multiple times, although later runs may not |
|
364 |
have the desired effect. |
|
365 |

366 |
Note that @{tool mkdir} is unable to change @{verbatim IsaMakefile} |
|
367 |
incrementally --- manual changes are required for multiple |
|
368 |
sub-sessions. On order to get an initial working session, the only |
|
369 |
editing needed is to add appropriate @{ML use_thy} calls to the |

The @{verbatim "-I"} option specifies an alternative to @{verbatim |
|
378 |
IsaMakefile} for dependencies. Note that ``@{verbatim "-"}'' refers |
|
379 |
to \emph{stdout}, i.e.\ ``@{verbatim "-I-"}'' provides an easy way |

380 |
to peek at @{tool mkdir}'s idea of @{tool make} setup required for |
|
381 |
some particular of Isabelle session. |
|
382 |

383 |
\medskip The @{verbatim "-P"} option includes a target for the |
|
384 |
parent @{verbatim LOGIC} session in the generated @{verbatim |

IsaMakefile}. The corresponding sources are assumed to be located |
|
386 |
within the Isabelle distribution. |

388 |
\medskip The @{verbatim "-b"} option sets up the current directory |
|
389 |
as the base for a new session that provides an actual logic image, |
|
390 |
as opposed to one that only runs several theories based on an |
|
391 |
existing image. Note that in the latter case, everything except |

392 |
@{verbatim IsaMakefile} would be placed into a separate directory |

Basically, there are two different modes of operation: \emph{build |
|
491 |
mode} (enabled through the @{verbatim "-b"} option) and |
|
492 |
\emph{example mode} (default). |
|
493 |
||
494 |
Calling @{tool usedir} with @{verbatim "-b"} runs @{executable |
|
495 |
"isabelle-process"} with input image @{verbatim LOGIC} and output to |
|
496 |
@{verbatim NAME}, as provided on the command line. This will be a |
|
497 |
batch session, running @{verbatim ROOT.ML} from the current |
|
498 |
directory and then quitting. It is assumed that @{verbatim ROOT.ML} |
|
499 |
contains all ML commands required to build the logic. |
|
500 |
||
28238 | 501 |
In example mode, @{tool usedir} runs a read-only session of |
28221 | 502 |
@{verbatim LOGIC} and automatically runs @{verbatim ROOT.ML} from |
503 |
within directory @{verbatim NAME}. It assumes that this file |
|
504 |
contains appropriate ML commands to run the desired examples. |
|
505 |
||
506 |
\medskip The @{verbatim "-i"} option controls theory browser data |
|
507 |
generation. It may be explicitly turned on or off --- as usual, the |
|
508 |
last occurrence of @{verbatim "-i"} on the command line wins. |
|
509 |
||
510 |
The @{verbatim "-P"} option specifies a path (or actual URL) to be |
|
511 |
prefixed to any \emph{non-local} reference of existing theories. |
|
512 |
Thus user sessions may easily link to existing Isabelle libraries |
|
513 |
already present on the WWW. |
|
514 |
||
515 |
The @{verbatim "-m"} options specifies additional print modes to be |
|
516 |
activated temporarily while the session is processed. |
|
517 |
||
518 |
\medskip The @{verbatim "-d"} option controls document preparation. |
|
519 |
Valid arguments are @{verbatim false} (do not prepare any document; |
|
520 |
this is default), or any of @{verbatim dvi}, @{verbatim dvi.gz}, |
|
521 |
@{verbatim ps}, @{verbatim ps.gz}, @{verbatim pdf}. The logic |
|
522 |
session has to provide a properly setup @{verbatim document} |
|
523 |
directory. See \secref{sec:tool-document} and |
|
524 |
\secref{sec:tool-latex} for more details. |
|
525 |
||
526 |
\medskip The @{verbatim "-V"} option declares alternative document |
|
527 |
versions, consisting of name/tags pairs (cf.\ options @{verbatim |
|
528 |
"-n"} and @{verbatim "-t"} of the @{tool_ref document} tool). The |
|
529 |
standard document is equivalent to ``@{verbatim |
|
530 |
"document=theory,proof,ML"}'', which means that all theory begin/end |
|
531 |
commands, proof body texts, and ML code will be presented |
|
532 |
faithfully. An alternative version ``@{verbatim |
|
533 |
"outline=/proof/ML"}'' would fold proof and ML parts, replacing the |
|
534 |
original text by a short place-holder. The form ``@{text |
|
535 |
name}@{verbatim "=-"},'' means to remove document @{text name} from |
|
536 |
the list of versions to be processed. Any number of @{verbatim |
|
537 |
"-V"} options may be given; later declarations have precedence over |
|
538 |
earlier ones. |
|
539 |
||
540 |
\medskip The @{verbatim "-g"} option produces images of the theory |
|
541 |
dependency graph (cf.\ \secref{sec:browse}) for inclusion in the |
|
542 |
generated document, both as @{verbatim session_graph.eps} and |
|
543 |
@{verbatim session_graph.pdf} at the same time. To include this in |
|
544 |
the final {\LaTeX} document one could say @{verbatim |
|
545 |
"\\includegraphics{session_graph}"} in @{verbatim |
|
546 |
"document/root.tex"} (omitting the file-name extension enables |
|
547 |
{\LaTeX} to select to correct version, either for the DVI or PDF |
|
548 |
output path). |
|
549 |
||
550 |
\medskip The @{verbatim "-D"} option causes the generated document |
|
551 |
sources to be dumped at location @{verbatim PATH}; this path is |
|
552 |
relative to the session's main directory. If the @{verbatim "-C"} |
|
553 |
option is true, this will include a copy of an existing @{verbatim |
|
554 |
document} directory as provided by the user. For example, |

|
561 |
facilitates debugging of serious {\LaTeX} errors, for example. |

for internal proof objects, see also the \emph{Isabelle Reference |
|
565 |
Manual}~\cite{isabelle-ref}. |
|
566 |

31688 | 567 |
\medskip The @{verbatim "-t"} option produces a more detailed |
568 |
internal timing report of the session. |
|
569 |
||
28221 | 570 |
\medskip The @{verbatim "-v"} option causes additional information |
571 |
to be printed while running the session, notably the location of |
|
572 |
prepared documents. |
|
573 |
||
574 |
\medskip The @{verbatim "-M"} option specifies the maximum number of |
|
575 |
parallel threads used for processing independent tasks when checking |
|
576 |
theory sources (multithreading only works on suitable ML platforms). |
|
28238 | 577 |
The special value of @{verbatim 0} or @{verbatim max} refers to the |
578 |
number of actual CPU cores of the underlying machine, which is a |
|
579 |
good starting point for optimal performance tuning. The @{verbatim |
|
580 |
"-T"} option determines the level of detail in tracing output |
|
581 |
concerning the internal locking and scheduling in multithreaded |
|
582 |
operation. This may be helpful in isolating performance |
|
583 |
bottle-necks, e.g.\ due to excessive wait states when locking |
|
584 |
critical code sections. |

637 |
Isabelle batch process, provided document preparation has been |
|
638 |
enabled (cf.\ the @{verbatim "-d"} option of the @{tool_ref usedir} |

\medskip The @{verbatim "-c"} option tells the @{tool document} tool |
|
644 |
to dispose the document sources after successful operation. This is |
|
645 |
the right thing to do for sources generated by an Isabelle process, |

\medskip The @{verbatim "-n"} and @{verbatim "-o"} option specify |
|
649 |
the final output file name and format, the default is ``@{verbatim |

|
651 |
the target @{verbatim DIR}. |
|
652 |

653 |
\medskip The @{verbatim "-t"} option tells {\LaTeX} how to interpret |

654 |
tagged Isabelle command regions. Tags are specified as a comma |
|
655 |
separated list of modifier/name pairs: ``@{verbatim "+"}@{text |
|

foo}'' (or just ``@{text foo}'') means to keep, ``@{verbatim |
|
657 |
"-"}@{text foo}'' to drop, and ``@{verbatim "/"}@{text foo}'' to |

fold text tagged as @{text foo}. The builtin default is equivalent |

\medskip Document preparation requires a properly setup ``@{verbatim |
|
666 |
document}'' directory within the logic session sources. This |
|
667 |
directory is supposed to contain all the files needed to produce the |
|
668 |
final document --- apart from the actual theories which are |
|
669 |
generated by Isabelle. |
|
670 |
||
671 |
\medskip For most practical purposes, the @{tool document} tool is |
|
672 |
smart enough to create any of the specified output formats, taking |
|
673 |
@{verbatim root.tex} supplied by the user as a starting point. This |
|
674 |
even includes multiple runs of {\LaTeX} to accommodate references |
|
675 |
and bibliographies (the latter assumes @{verbatim root.bib} within |
|
676 |
the same directory). |
|
677 |
||
678 |
In more complex situations, a separate @{verbatim IsaMakefile} for |
|
679 |
the document sources may be given instead. This should provide |
|
680 |
targets for any admissible document format; these have to produce |
|
681 |
corresponding output files named after @{verbatim root} as well, |
|
682 |
e.g.\ @{verbatim root.dvi} for target format @{verbatim dvi}. |
|
683 |
||
684 |
\medskip When running the session, Isabelle copies the original |
|
685 |
@{verbatim document} directory into its proper place within |
|
28238 | 686 |
@{setting ISABELLE_BROWSER_INFO} according to the session path. |
28221 | 687 |
Then, for any processed theory @{text A} some {\LaTeX} source is |
688 |
generated and put there as @{text A}@{verbatim ".tex"}. |
|
689 |
Furthermore, a list of all generated theory files is put into |
|
690 |
@{verbatim session.tex}. Typically, the root {\LaTeX} file provided |
|
691 |
by the user would include @{verbatim session.tex} to get a document |
|
692 |
containing all the theories. |
|
693 |
||
694 |
The {\LaTeX} versions of the theories require some macros defined in |
|
28238 | 695 |
@{"file" "~~/lib/texinputs/isabelle.sty"}. Doing @{verbatim |
696 |
"\\usepackage{isabelle}"} in @{verbatim root.tex} should be fine; |
|
697 |
the underlying Isabelle @{tool latex} tool already includes an |
|
698 |
appropriate path specification for {\TeX} inputs. |
|
28221 | 699 |
|
700 |
If the text contains any references to Isabelle symbols (such as |
|
701 |
@{verbatim "\\"}@{verbatim "<forall>"}) then @{verbatim |
|
28238 | 702 |
"isabellesym.sty"} should be included as well. This package |
703 |
contains a standard set of {\LaTeX} macro definitions @{verbatim |

For proper setup of DVI and PDF documents (with hyperlinks and |

The @{tool_def latex} utility provides the basic interface for |
|
733 |
Isabelle document preparation. Its usage is: |
|
734 |
\begin{ttbox} |
|
735 |
Usage: latex [OPTIONS] [FILE] |
|
736 |
||
737 |
Options are: |
|
738 |
-o FORMAT specify output format: dvi (default), dvi.gz, ps, |
|
739 |
ps.gz, pdf, bbl, idx, sty, syms |
|
740 |
||
741 |
Run LaTeX (and related tools) on FILE (default root.tex), |
|
742 |
producing the specified output format. |
|
743 |
\end{ttbox} |
|
744 |
||
745 |
Appropriate {\LaTeX}-related programs are run on the input file, |
|
746 |
according to the given output format: @{executable latex}, |
|
747 |
@{executable pdflatex}, @{executable dvips}, @{executable bibtex} |
|
748 |
(for @{verbatim bbl}), and @{executable makeindex} (for @{verbatim |
|
749 |
idx}). The actual commands are determined from the settings |
|
750 |
environment (@{setting ISABELLE_LATEX} etc.). |
|
751 |
||
752 |
The @{verbatim sty} output format causes the Isabelle style files to |
|
753 |
be updated from the distribution. This is useful in special |
|
754 |
situations where the document sources are to be processed another |
|
755 |
time by separate tools (cf.\ option @{verbatim "-D"} of the @{tool |
|
756 |
usedir} utility). |
|
757 |
||
758 |
The @{verbatim syms} output is for internal use; it generates lists |
|
759 |
of symbols that are available without loading additional {\LaTeX} |
|
760 |
packages. |
