About:
Gauche is an R5RS Scheme implementation that aims to be a handy tool
for daily work. Quick startup, a built-in system interface, and native
multilingual support are some of its goals. It has an OO system
similar to STklos and Guile. It supports UTF-8, EUC-JP, and Shift-JIS
multibyte encodings natively.

Gauche is the Scheme I always wanted
by Evan Prodromou - Feb 20th 2006 07:18:35
I've been looking for a solid, high-performance Scheme implementation for
general scripting and systems programming for several years now. I was
really happy to find Gauche. It has an extensive library of support
functions and binary extensions and great support for SRFIs (Scheme
Requests for Implementation -- the "open standards" of the Scheme
world).
Most "modern" scripting issues -- networking, XML parsing, text
manipulation, Web programming, embedding and extending -- are nicely
handled with clean interfaces.
I think that programmers who are looking for top-notch alternative to
Python and Perl -- the crowd that is moving to e.g. Ruby and Groovy --
should take a close look at Gauche as a real alternative.

WHAT ??

Somebody please tell me what the HECK is R5RS..
What I mean is that how can something that most people probably won't
understand the meaning of, be handy in daily work ??

R5RS stands for Revised^5 Report on the Algorithmic Language Scheme",
the "standard" of the Scheme language.
IMHO, handy tools need not be what is obvious to those who are not
familiar with it,
although to be so may be a plus. If you're curious, take a look at the
following article:
Being popular
Of course, people can have different view.

It could be useful to compare [feature by feature] Gauche vs Guile. That
would help to choose a right Scheme for the right project. Guile was here
for awhile, why would we need another Scheme? Is there anything wrong with
Guile?
I would recommend to compare first of all the following features: XML
processing (including XPath and RDF), integration with web servers (CGI,
Apache modules, standalone HTTPD), integration with GUI (like GNOME, QT or
Win32), database API (PostgreSQL, MySQL), other communications (CORBA,
SOAP).
Also, it would be useful to show the best and typical applications using
Gaucho.

Good point. There's nothing wrong with Guile, but
simply there are some features I needed that
are (or were) not in Guile and was difficult to add
to the existing implementation without changins its design policy.
(1) Native multibyte string handling. I wanted string-ref
(and its corresponding C API) to work correctly on a string that mixes
latin and japanese characters. So as read-char. So as regexp.
If it were easy to modify existing implementation to
realize this, I'd done that. What I found was that
the change would affect everywhere in the code. and sometimes it
sacrifices the performance, so some users will not want to have it.
(2) Use of Boehm GC. This is also a fundamental design policy issue.
Changing this affects everywhere
in the code.
(3) VM architecture. The choice of interpreter engine
greatly affects the interface how C-defined procedure
is called. It is very difficult to change one to the other after you
wrote large number of C-defined procedures.
(4) Licensing issue. I'm not anti-GNU, but there are certain cases that I
have to avoid GNU-ed code to achieve my goal.
I have certain applications I want to write in Gauche,
and design decisions are made according to that goal.
Those design decisions need not agree with Guile's.
I don't want to reinvent every wheels. I'm trying to
keep the Scheme-level interface compatible to
existing implementations as much as possible, so that
the Scheme modules written in other implementations
can be easily ported to Gauche.

Oleg Kiselyov's SXML runs on Gauche. So on Guile.

No standalone httpd, or Apache module.
Simple CGI module is provided, but the API is
Gauche specific.

Not yet.

As I mentioned above, I started Gauche
to satisfy the requirements for the applications
I wanted to write. (Writing Scheme implementation
is not my goal; it's just a preparation).
Once Gauche become stable, I'll start writing applications.
Meanwhile, Gauche looks like some 'yet another premature Scheme
implementation'.
If you need features like GUI or Database
binding immediately, I don't recommend Gauche.
If you deal with multibyte documents, however,
Gauche may be some use.
