Announcement
============
The members of the Components Team at Lawrence Livermore
National Laboratory <components@llnl.gov> are pleased to
announce the beta release of Babel, version 0.10.2.
What's New
==========
The following features have been added, or completed, in
this release:
+ Fixed Roundup issues: 90, 91, 92, 93, 98, 103, 104, 106,
114, 122, 124, 126, 127, 128, 131, 133, 135
+ Add support for GCC 4.0 (based on prereleases) and gfortran
+ Enable more Fortran 90 function overloading
+ Allow developers to replace libsidl's mechanism for finding
types in libraries with their own mechanism for MOCCA CCA.
+ Undocumented prototype of assertion mechanism
+ Reduce the number of F90 stub files generated by
combining the _array.F90 into the normal stub file.
+ General Python binding upgrade.
+ Significantly reduce the amount of array copying that occurs
with the Python binding.
+ Python stub classes now have an inheritance structure that
matches the inheritance in the SIDL file.
+ Make "self" a keyword.
(Also refer to the CHANGES file for more details.)
What Babel Is
=============
Babel is designed to address problems of language
interoperability, particularly in scientific/engineering
applications. At the simplest level, Babel generates glue
code so that libraries written in one programming language
are callable from other programming languages. Babel
generates this glue code from an interface description
written in SIDL, our Scientific Interface Definition
Language. Babel supports full Object-Oriented features
and exception handling even in non-OO languages such as C
or Fortran77.
Supported Languages
===================
Babel currently supports calling libraries written in
C, C++, Fortran77, Fortran90, Java, or Python from drivers written
in either C, C++, Fortran77, Fortran90, Python or Java. (Python
support also requires the Numerical Python set of extensions at
http://numpy.sourceforge.net/ ). Fortran90 requires CHASM 1.0.1 (or
later) to be installed before Babel. Chasm 1.2.0 is required to use
the gfortran F90 compiler.
Supported Platforms
===================
Linux
Solaris
AIX (except Python)
(More expected in next few months.)
Broken Platforms (hopefully to be resurrected)
==============================================
Cygwin
Caveat
======
Babel is research in progress. This is a beta release
looking for more friendly users and now some power users.
Babel has been used on a few real projects now, there
are still too few examples, but the documentation is
improving.
Availability
============
The software is available for free download at
http://www.llnl.gov/CASC/components
User Resources
==============
Two email lists have been set up for the Babel community:
babel-users@llnl.gov (unmoderated discussions)
babel-announce@llnl.gov (announcements only)
To subscribe to one or both of these email lists, send
email to <majordomo@lists.llnl.gov> with the text
"subscribe babel-announce", "subscribe babel-users",
or both (one per line).
Contacting the Authors
======================
If you have any questions or concerns with the installation
process or usage of Babel, feel free to contact the project team
at components@llnl.gov. To report bugs or suggest feature
enhancements, please submit a report in the bug database at
https://www.cca-forum.org/bugs/babel/, or send email to
babel-bugs@cca-forum.org.
