ANN: Ypsilon - R6RS Scheme System for real-time applications
y.fuji...@gmail.com
applications is now available at:
http://code.google.com/p/ypsilon/
Version 0.9.5 beta release:
* It implements mostly concurrent mark & sweep garbage collector
to achieve minimal gc pause time and best performance on multi-core
CPU.
* Runs as a stand-alone interpreter on Linux(x86), Mac OS X(x86),
Windows Vista(x86).
* Backtrace feature with source code information for easy debugging.
* Auto-compile-cache feature to speed-up edit/run cycle in
development.
* Implements full and complete features of R6RS and R6RS standard
libraries.
* It is planned to develop a library which can embed to various
applications
as well as adding a native code generation feature to a virtual
machine.
* Current version runs faster than Petite Chez v7.4 with Linux
running on
Intel Core2 Duo in 10 out of 12 gabriel benchmarks.
I would be grateful for receiving any kind of bug reports especially
for
any malfunction about R6RS conformance since I'm not a specialist of
The Scheme Programming Language though I am an experienced programmer.
Thank you in advance.

Nice Glut demo as well. Kudos on a nice scheme interpreter.

Just downloaded and tried this on OS X (Leopard). Very nice. I'm
impressed. I was very impressed with how simple the FFI is and how
quickly I could make a very simple GLUT/OpenGL test program. The
backtracing feature for errors was also incredibly useful and
compromised just the right amount of readability and usefulness.
Bravo! Also, thank you *VERY* much for putting all the various project/
solution files in the download package!
The only few things I'd comment on requiring additional work:
* make check just hung on OS X. Everything was still good, but I don't
know what test it was on to give you more info.
* Not dying on Bus Errors. Using the FFI, I got these a few times. I
know that is tough, but having all my work just disappear because of a
typo sucks. :-(
I'll be playing with this some more over time. Looks very promising.
Definitely don't stop.
Can I ask what the impetus of creating it was?

PS: feel free to comment on that table/page - should I move it to some

I have started the development of Ypsilon four years ago :)
Thank you!
