Release Notes

Release notes for IronScheme 1.0 Beta 1

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.
With 1.0 beta 1, IronScheme implements the entire R6RS Scheme standard, and only fail 16 of 8897 tests in the PLT R6RS test suite.
IronScheme runs on MS .NET and Mono.

Notably lacking for R6RS

  • call/cc only supports escape continuations, trying to re-invoke a continuation will result in an error


  • all raise's are continuable in the sense they can be caught


  • 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


  • Abdulaziz Ghuloum and Kent Dybvig for psyntax (and friends)
  • Derick Eddington for making SRFI-1 R6RS compatible
  • Philip L. Bewig for SRFI-41
  • 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)

  • Visual Studio 2008 SP1 plugin
  • A tiny MVC web framework
  • Added a lot of documentation, more to come
  • Many bug fixes
  • See 'Source Code' page for more details

Reviews for this release

Very useful way to embed Scheme into .NET application. Great work!
