ANN: IronScheme 1.0 beta 3
leppie
What is IronScheme?
IronScheme will aim to be a conforming R6RS Scheme implementation on
the Microsoft DLR.
IronScheme provides 2 run modes: either via direct invocation on the
commandline or via a REPL interactive environment.
IronScheme can also used an embedded scripting library in your .NET
programs.
With 1.0 beta 3, IronScheme implements the entire R6RS Scheme
standard, and only fail 6 of 8871 tests in the PLT R6RS test suite.
IronScheme runs on MS .NET and Mono. Unfortunately, it does not seem
to work under 64bit on Mono.
Notably lacking for R6RS
* call/cc only supports escape continuations, trying to re-invoke
a continuation will result in an error
* during development of beta 2, I made a CPS version, but is too
slow to be useful currently, this will be addressed in IronScheme 2.0
Differences
* all raise's are continuable in the sense they can be caught
(this is also addressed with the CPS version)
Extras
* a generic load procedure for toplevel R6RS files
* many extras procedures and macros in (ironscheme) library,
mostly provided by psyntax
* syntactic CLR integration, automatic conversion of closures into
delegates
Credits
* Abdulaziz Ghuloum and Kent Dybvig for psyntax (and friends) (and
equal?)
* Marc Feeley for pretty-print
* anyone else I missed
Planned to-do's (before final release)
* testing of anything else
* any additional CLR integration required
* documentation
Updated (fixed/new)
* Converted a substantial part of code still written in C# into
Scheme
* Some minor compiler optimizations
* Improvements with exactness of numbers
* Added -I switch for extra library search paths
* Added -emacs switch to let the REPL behave better as a
subprocess (as well as auto-detection of this)
* Added extensions library for easy calling from .NET
* Added remoting library (connects with REPL)
