Subject: LAML SchemeDoc - Documentation of Scheme Libraries

As part of the development of LAML I have - through the last 6 years -
constructed a tool for extraction of API documentation from Scheme
source files. Until now, SchemeDoc has been one of several tools in
the LAML distribution. I have used the tool extensively for documentation of
my own software. It is called LAML SchemeDoc, to separate it from
other attempts in the same direction, and to emphasize the relations
with similar tool for other languages (such as the well-known Javadoc
and Doxygen).

It is now possible to download LAML SchemeDoc separately (without 
unnecessary LAML context) from the SchemeDoc home page:

On request I've added example code to the SQLI/SQLD
web pages. You can find it at:

1. HtmlPrag 0.14 has been released.

2. Other recent releases of packages:

3. If you have a contact at ISO or ANSI, please let me know.  I have a
   pretty extensive implementation of much of ISO 8601, but am having
   trouble getting ISO to open up the latest version of the spec.

4. If you're in the Boston area and not yet on the very-low-traffic
   Bothton list, please join at "http://www.bothton.org/".  We already
   have 46 members, and very few of those are from the universities.

5. Especially now that I'm job-hunting, I'm trying to promote my brand
   (or at least my Google juice).  If you use one of my Scheme libraries
   in your project, I'd appreciate a link or mention on your project's
   Web page/site.

Subject: A more hygienic SYNTAX-CASE implementation

I would like to announce version 1 of the syntax-case implementation
to be found at:

Subject: Portable macro and modules - version 1

I would like to announce version 1 of the portable macros 
and modules system for Scheme, to be found at:

  http://www.het.brown.edu/people/andre/macros/index.htm

A portable implementation of hygienic macros and modules for Scheme. 
Among other novel features, it addresses a large class of variable capture
problems that are often overlooked in existing hygienic procedural macro
systems. It also introduces a new primitive for breaking hygiene that leads
to better behaviour of unhygienic macros under composition. It includes
SYNTAX-CASE and it contains a novel module system with a very
programmer-friendly semantics.

From: Michael Sperber <sperber@informatik.uni-tuebingen.de>
Subject: Scheme 48 1.3 available

Scheme 48 is an implementation of Scheme written by Richard Kelsey and
Jonathan Rees. It is based on a byte-code interpreter and is designed
to be used as a testbed for experiments in implementation techniques
and as an expository tool. It comes with a module system, an extensive
set of libraries, an interactive command-line-based development
environment and a manual in various formats. Scheme 48 runs on most
Unix/Linux systems, as well as Windows NT, 2000, and XP, and is fully
R5RS-conformant.

Scheme 48 is available (under a very liberal license) from 

http://www.s48.org/ 

Scheme 48 1.3 is a significant feature release.  Among the things
added was an experimental Windows port, a Concurrent ML library,
integration for SRFIs 34-36 (exceptions and conditions), and a new
infrastructure for dynamically loading external libraries.  As usual,
we also fixed a number of bugs.  For details, refer to the attached
release notes and the documentation.

Subject: ROOS Version 0.33

I'd like to announce ROOS, an OO implementation
for Scheme.
It is used as an OO system for mzgtk2, which is a mzscheme
binding to gtk2 that's currently being developed.

There has been a lot of development on ROOS lately.
The implementation is pretty complete now.
Persistent ROOS is under development.

Subject: datastructs v0.25

I've released 'datastructs' version 0.25, which
provides a couple of datastructures for mzscheme.

Changes:

     - Fixed bug in sets.scm,set-filter would return
       an AVL Tree instead of a SET.

Subject: Persistent ROOS

I'd like to announce Persistent ROOS, a Transparent
OO Persistence implementation for ROOS.

It has been implemented for mzscheme.

It persists data members of ROOS objects that have
been declared persistent. Works like 'getters' and
'setters'.

Persistent ROOS is under development and must be
considered alpha/beta code.

Subject: SISCweb 0.22 - Stateful Scheme web framework for J2EE

I would like to announce the release of SISCweb v0.22, available at:
 http://siscweb.sf.net/

CHANGES

This release fixes a couple of bugs and completes the basic feature
set introduced in the previous release. [...]

OVERVIEW

SISCweb is a framework to facilitate writing stateful Scheme web
applications in a J2EE environment.

Through the use of continuations, SISCweb does away with the
page-centric execution model typical of web programming. Every time a
response is sent to the browser, the program execution flow is
suspended, to be then resumed from that exact point when the browser
submits a request.

From: Hans Oesterholt-Dijkema <hdnews@gawab.com>
Subject: spodcxx v0.22

I've released 'spodcxx' version 0.22, which
provides a sPOD 2 HTML converter. SPOD is
a superset of POD.

SPOD can be used to document scheme code.

This release fixes a small bug in wikiwikiwiki mode.

From: "Scott G\. Miller" <scgmille@freenetproject.org>
Subject: SISC 1.9.8 Released

This is a maintenance release for the 1.9.x series of SISC.  It contains
several bug fixes. [...]

SISC is an extensible heap-based interpreter of Scheme running on
the Java VM, with an aggressively optimized, lightweight (<200k)
Scheme engine.  SISC outperforms all existing Java
interpreters (often by more than an order of magnitude). [...]

Source code, binaries, and SISC documentation can be found on
the web at:

From: Alex Shinn <alexshinn@gmail.com>
Subject: Common-Scheme 0.2

New and improved!  Less ugly than before!  More half-tested modules!

Tired of manually porting between different Scheme implementations?
Fed up with preprocessors that ruin your source?  Wish Common-Lispers
would just shut up about Scheme's lack of portability and small library?
Common-Scheme may be for you.

Common-Scheme is a portable module system and collection of modules for
Scheme.  It is not a preprocessor - the same exact source works
unmodified on a number of implementations (currently Chicken, Gauche,
Guile and SISC).  The modules include portable regexps, networking and
process control, already making it a more modern and practical language
than portable Common-Lisp.

This is an initial beta release.  It's usable, but I'm still looking
for feedback, and the API is subject to change.

From: Eli Barzilay <eli@barzilay.org>
Subject: PLT Scheme v299.200

PLT Scheme v299.200 is now available from
    http://download.plt-scheme.org/

THIS IS A v300 ALPHA RELEASE.  Teachers and students using DrScheme
with "How to Design Programs" should wait for the final v300 release,
which will occur close to a new semester. [...]

The v300 series (including v299.200) is incompatible with the v200
series.  The most significant incompatibilities include (1) support
for Unicode breaks old programs that treat characters as bytes or
pathnames as strings; (2) case-sensitivity is now the default; and (3)
the built-in exception hierarchy has been revised.

Subject: beta of kawa 1.8 beta and new website preview available

Snapshots from the latest CVS sources, which should be fairly close to
what will hopefully very soon be released as Kawa/Qexo version 1.8:
ftp://bothner.com/pub/kawa-1.8beta.tar.gz  (source code)
ftp://bothner.com/pub/kawa-1.8beta.jar     (binary)

In addition I've been working on an updated and redesigned web page:
http://per.bothner.com/tmp/kawa/
Of course this is a temporary location; the final location will be:
http://www.gnu.org/software/kawa/
I hope the new web page/site is more appealing and useful (though
it is still automatically generated from the texinfo manual).
