Previous Releases
Version 0.93 (released in 1993) is still available but is no longer supported.Working Versions
Working versions are created for internal development purposes and vary in reliability and stability. Some are robust enough for noncritical research use, others are not. Please pay careful attention to the README or NEWS file for each version before attempting to use it. Current and recent working versions are listed in the Working Versions index, which gives access to README files for recent working versions and the ftp directories for working versions that are currently available for downloading. The installation instructions for the release version will generally work, mutatis mutandis, for working versions. Some older working versions can be found at ftp://ftp.research.bell-labs.com/dist/smlnj/working.
We generally announce new versions (including working versions) on
comp.lang.ml, comp.lang.functional, freshmeat.net, and our
development mailing list 
.
After version 110.9.1, the older "cmachine" (i.e. non-MLRISC) code generators were replaced by new MLRISC code generators, except for the MIPS architecture, which is currently not supported in the latest working version. Work on a new MIPS MLRISC code generator is in progress.
Packages
The directory
ftp://ftp.research.bell-labs.com/dist/smlnj/packages/.contains software packages that are not part of the core SML/NJ distribution. Currently, this directory contains:
- ckit, a C front end.
Benchmarks
A set of programs used as a "benchmark suite" for Standard ML is available at:
ftp://ftp.research.bell-labs.com/dist/smlnj/benchmarks/.
SML/NJ Compiler Test Suites
The regression test suites used for the SML/NJ compiler are available at:
ftp://ftp.research.bell-labs.com/dist/smlnj/testing/.
Contributed Software
Some contributed software packages can be found at
ftp://ftp.research.bell-labs.com/dist/smlnj/contrib/.Currently this directory contains:
- emacs
- The sml-mode package provides an emacs mode for editing
sml code under Gnu emacs and running the sml top-level as a subprocess of
emacs. Originally developed by Matthew J. Morley, it is now maintained
by Stefan Monnier (monnier at iro dot umontreal dot ca).
Online documentation is available here. The latest sml-mode tarball
is available at
http://www.iro.umontreal.ca/~monnier/elisp/.
- tools
- Various software tools, including:
- heap2exec, Lorenz Huelsbergen's "heap2exec" utility for building Unix executables from heap images and the SML/NJ runtime executable.
- lexgenmos.tar.Z, a translation of the Moscow ML lexer generator, which produces lexers that run a bit faster than the improved ML-Lex in working version 110.7.
- lib
- Some contributed or "borrowed" libraries, including:
- CGI.tar.Z, a port of Moscow ML's CGI library.
- Util.tar.Z, utility modules contributed by Nikolai Bjorner and Matthias Blume.
- getopt.tar.Z, a port (via Haskell) of the GNU getopt library.
Additional packages will be added as they become available. New contributions are eagerly sought!
