Announcing Gwydion Dylan 2.0 Gwydion Dylan is freely available implementation of a dynamic language resembling the language defined in the Dylan Reference Manual. Gwydion Dylan differs in a number of ways from the official Dylan language definition. See our documentation for details. See the copyright notice for the conditions under which Gwydion Dylan is made available. Dylan(TM) is a trademark of Apple Computer Corp. Gwydion Dylan provides two different execution engines: d2c (new in version 2.0) An optimizing Dylan to C compiler which offers reasonably good runtime speed. Compilations are relatively slow and debugging facilities are less convenient that in Mindy. Mindy A byte-code compiler which offers extremely fast compilation, reasonably good debuggability, and slow runtime speed. Mindy is also somewhat more portable than d2c, and is available on more platforms. This is an update of our earlier Mindy releases. Release URL: All source and binary distributions and the documentation are available at: http://legend.gwydion.cs.cmu.edu/gwydion/dylan Currently Gwydion Dylan is believed to work on these platforms [actual build platform in brackets]: HPPA HP/Ux [9.03], x86 Microsoft Windows 32 [NT 4.0], x86 Linux [Red Hat 4.0/2.0.18], Sparc Solaris [Sparc 4 Sunos 5.5] Yes, it does seem to run on Windows 95, but has not been extensively used there. Note that Mindy can be built from sources on many other Unix platforms, notably AIX and Irix. Past versions of Mindy have also been built on Mac. Support and Disclaimer This software is made available "as is". Neither the authors nor Carnegie Mellon University make any warranty whatsoever concerning the software, its performance, or its conformity to any specification. Gwydion is a small research project, and most of our effort in the near future will be devoted to developing a "hypercode" programming environment. The amount of time and effort we can put into supporting this release is extremely limited. We will try to answer mail to "gwydion-bugs@cs.cmu.edu", but we can't guarantee that our replies will be timely or that we will fix every bug reported. We are releasing the Gwydion Dylan source so that users can fix things for themselves if they choose to do so. We encourage users to send improvements and bug-fixes to us so that we can add them to future releases.
