The question is wrong; you have not said what you mean by ``Scheme''. If you mean the language that is defined by the (de-facto) standard ``Revised^3 Report on the Algorithmic Language Scheme'', then the answer is certainly ``no''. The standard does not define, for instance, how foreign language functions can be called from within Scheme (you would need this for an interface to the Xlib), or how a 32-bit value can be read from a socket (which would be needed when the Xlib is by-passed; CLX does this). If by ``Scheme'' you mean MIT-Scheme (C-Scheme), then the answer is ``I don't know''. But from what I have read in a Scheme mailing list, I assume that the MIT-Scheme implementors are having lots of other, more important work items in their queue. If by ``Scheme'' you mean ``any implementation of Scheme'', then the answer is ``Yes, someone has done this'', for instance, I am currently working on such an integration (it's nearly finished). I am doing this for my own Scheme interpreter (which accepts a superset of the Scheme defined by the R^3RS); since this involves non-portable language features it would probably be of no value for someone who doesn't also have that particluar Scheme implementation. The functions provided by the X11/Scheme integration are roughly equivalent to those offered by CLX (but, of course, more Scheme-oriented, e.g. no setf functions, no :keywords, etc.). If someone is interested in details, just send me a letter. Needless to say, I would also like to hear from people who are doing or have done an X11/Scheme integration for any Scheme implementation. -- Regards, Oliver Laumann, Technical University of Berlin, Germany. ...!pyramid!tub!net or net@TUB.BITNET ...!mcvax!unido!tub!net
