Today I released version 2.11 of Wraith Scheme, which is a
shareware and open-source full R5 Scheme implementation for the

Dear all,
Chicken Scheme 4.4.0 is available for download from here:

tail-call recursion, first-class continuations, and has a very

asynchronous resources + continuations + continuable exceptions

1 hour 4 min ago
Ciao,
I am looking for a way to handle asynchronous resources finalisation
in such a way that both continuations and continuable exceptions are
allowed; if I exclude garbage collector-related finalisation
mechanisms (guardians, ...) I do not see how to do it in an efficient/
convenient way.
Putting the finalisation form in the OUT-GUARD of a DYNAMIC-WIND

scheme FAQ

I purusing comp.lang.schem and I noticed mention of a FAQ. Some of the
questions looked quite interesting. The link given

seemed to be broken. Is this FAQ still around (there is a site called
"scheme FAQ" but it doesn't seem to be the same thing).

I wanted to let interested parties know that I have uploaded new versions
of my nedit.rc file and scheme.calltips files to my gopher server:

Nested quasiquotation question.

1 hour 4 min ago
Hi all.
In the expression:
`(a `(b ,(+ 1 2) ,(foo ,(+ 1 3) d) e) f)
that evaluates to
(a (quasiquote (b (unquote (+ 1 2)) (unquote (foo 4 d)) e)) f)
Why (+ 1 3) is evaluated and (+ 1 2) not?

query: nature of syntax-rules

1 hour 4 min ago
I am curious about an aspect of syntax-rules and my
curiosity gives rise to a history and "nature of" question
about syntax rules.
One of the curious facts about syntax-rules is that it
specifies transformations of source with a kind of
semi-agnosticism about whether the output of a
transformation is an expression or a syntactic datum.

Implementations for parallel programming?

1 hour 4 min ago
Which Scheme implementations allow to write parallel programs?
I require something beyond threads, e.g., based on MPI, in order
to run on a cluster.
Guile and Schemik offer convenient forms to use threads; other
implementations offer a more low-level interface. But I know none
that would allow to run a program in parallel on a cluster.

PLT 'load & run source/s' ?

1 hour 4 min ago
It's called 'successive refinement'.
-> non-X
-> mzscheme == shows blurb
-> ( + 2 3 ) == 5
-> experiment & find how to: ( exit) == OK
-> now write file: Sample1.ss == (+ 2 3 )
-> try: mzschem -f Sample1.ss == much IDE activity & exits
without output.
Please advise how do I start collecting and running my

implementing duodecimal numbers

Tue, 03/09/2010 - 09:00
I am interested in being able to do duodecimal (radix 12) arithmetic. Is
there a way to have for duodecimals something like the #b, #o, #x etc
notations for binary, octal, hex respectively? Can I define my own sharp
notation for a radix of my own choice and make it understood by the
interpreter as a number? How?

G'day everyone
My name is Bruce, and I'm a list lurker.
RosettaCode <[link]> is a programming language
task comparison site. I have no relationship to it other than that I'm
writing VBScript solutions to some of the tasks. Please take a look,
register and contribute your own solutions. I've benefited from seeing

On the Christmas I got a very nice gift(from myself to myself -

PLT without X ?

Fri, 03/05/2010 - 06:00
I can't sacrifice my main PC now, and I wasn't able to install
X on my spare PC - yet.
But the Debian DVD has got PLT-Scheme, which I'd like to
start experimenting with.
Can PLT-Scheme run without X?
== TIA.
