8 This directory contains the complete Isabelle system. To build and test the
9 entire system, including all object-logics, use the shell script make-all.
10 Pure Isabelle and each of the object-logics can be built separately using the
11 Makefiles in the respective directories; read them for more information.
15 The Makefiles can use two different Standard ML compilers: Poly/ML version
16 1.88MSX or later (from Abstract Hardware Ltd) and Standard ML of New Jersey
17 (Version 75 or later). Poly/ML is a commercial product and costs money,
18 but it is reliable and its database system is convenient for interactive
19 work. SML of New Jersey requires lots of memory and disc space, but it is
20 free and its code sometimes runs faster. Both compilers are perfectly
21 satisfactory for running Isabelle.
23 The Makefiles and make-all use enviroment variables that you should set
24 according to your site configuration.
26 ISABELLEBIN is the directory to hold Poly/ML databases or New Jersey ML
27 images. When using Poly/ML, ISABELLEBIN must be an absolute pathname (one
30 ML_DBASE is an absolute pathname to the initial Poly/ML database (not
31 required for New Jersey ML).
33 ISABELLECOMP is the ML compiler, typically "poly -noDisplay" or "sml". If
34 ISABELLECOMP begins with the letters "poly" then the Makefiles assume that
35 it is Poly/ML; if it begins with the letters "sml" then they assume
36 Standard ML of New Jersey.
39 STRUCTURE OF THIS DIRECTORY
41 The directory Pure containes pure Isabelle, which has no object-logic.
43 Other important files include...
44 COPYRIGHT Copyright notice and Disclaimer of Warranty
45 make-rulenames shell script used during Make
46 make-all shell script for building entire system
47 expandshort shell script to expand "shortcuts" in files
48 prove_goal.el Emacs command to change proof format
49 xlisten shell script for running Isabelle under X
50 teeinput shell script to run Isabelle, logging inputs to a file
51 theory-template.ML template file for defining new theories
52 Pure directory of source files for Pure Isabelle
53 Provers directory of generic theorem provers
55 xlisten sets up a window running Isabelle, with a separate small "listener"
56 window, which keeps a log of all input lines. This log is a useful record
57 of a session. If you are not running X windows, teeinput can still be used at
58 least to record (if not to display) the log.
60 The following subdirectories contain object-logics:
61 FOL Natural deduction logic (intuitionistic and classical)
62 ZF Zermelo-Fraenkel Set theory
63 CTT Constructive Type Theory
64 HOL Classical Higher-Order Logic
65 LK Classical sequent calculus
66 Modal The modal logics T, S4, S43
67 LCF Logic for Computable Functions (domain theory)
68 Cube Barendregt's Lambda Cube
70 Object-logics include examples files in subdirectory ex or file ex.ML.
71 These files can be loaded in batch mode. The commands can also be
72 executed interactively, using the windows on your workstation. This is a
73 good way to get started.
75 Each object-logic is built on top of Pure Isabelle, and possibly on top of
76 another object logic (like FOL or LK). A database or binary called Pure is
77 first created, then the object-logic is loaded on top. Poly/ML extends
78 Pure using its "make_database" operation. Standard ML of New Jersey starts
79 with the Pure core image and loads the object-logic's ROOT.ML.
