The Isabelle System Distribution
This is Isabelle98 as of January 1998. Compared to
the Isabelle94 line it introduces many new features, but also some
imcompatibilities. See the NEWS file in the distribution for
Isabelle requires a real Unix box with sufficient resources. Fun
starts at about 32MB of memory (somewhat depending on your ML system),
with several tens of MB disk space and a relatively fast CPU.
Furthermore, it needs the following software, which is not part of the
- A full Standard ML Compiler (e.g. Poly/ML or SML of New Jersey).
- The GNU bash shell (version 1.x or 2.x).
- Perl 5.x - the Pathologically Eclectic Rubbish Lister.
The following ML system and platform combinations are known to work
- Poly/ML versions 2.x and 3.1 on Suns.
- SML/NJ 0.93 on Suns and SGIs. There seem to be several
problems with Linux and HP-UX.
- SML/NJ versions 109.27 to 109.33 on Suns, Linux, etc.
- SML/NJ 110 on Suns, Linux, etc.
Poly/ML is a
commercial product and costs money, but it is stable and efficient. It
requires relatively little memory (starting at about 16MB) and disk
space (about 40MB for all distributed object logics).
SML/NJ needs lots of store and disk space, but it is free.
The current official release is 110. We also still support the old
0.93 release and working versions 109.27 to 109.33. Support for the
109 line of SML/NJ will be dropped next time! There is an unofficial
pre-built binary distribution of SML/NJ
110 for Linux.
See file INSTALL in the Isabelle sources on how to build the
system. Further background information may be found in the
Isabelle System Manual, distributed as dvi with the
The distribution includes only a very primitive interface based on
ordinary terminal sessions.
David Aspinall has written a more elaborate user interface
for Isabelle. It runs under recent versions of GNU Emacs and XEmacs,
the latter being recommended. It's useful to both novices and
