Currently Ypsilon development has been suspended due to the development of our new pinball title MAD DAEDALUS -Loony Labyrinth Returns.
I will feed back the result of MAD DAEDALUS development to Ypsilon after the release of it in Spring 2010.
Till then, it may be difficult to answer to your bug reports. Please allow me some time to get back to you. I appreciate your patience.
Thank you for your great contribution for Ypsion.
OverviewYpsilon is the implementation of Scheme Programming Language, which conforms to the latest standard R6RS. It achieves a remarkably short GC pause time and the best performance in parallel execution as it implements "mostly concurrent garbage collection", which is optimized for the multi-core CPU system.
Ypsilon is easy to use as well as good for applications of any kind that require quick, reliable, and interactive data processing. It implements full features of R6RS and R6RS standard libraries including:
arbitrary precision integer arithmetic rational number exact and inexact complex number implicitly phased library top-level program proper tail recursion call/cc and dynamic wind unicode bytevectors records exceptions and conditions i/o syntax-case hashtables enumerations
More libraries are included to support a wide variety of software development. Also it has built-in FFI which is easy to use. Please refer to the following files for FFI overview.
