[bug#35082] [PATCH] gnu: Add kawa.

[Carlo Zancanaro]

[-- Attachment #1: Type: text/plain, Size: 759 bytes --]

The attached patch adds a package definition for Kawa. The 
synopsis and description differ from what guix lint suggests, but 
I'm not convinced that the suggested synopsis and description are 
better than what I have.

The suggested synopsis is "Java framework and implementation of 
Scheme, Elisp, and more", and the suggested description is "GNU 
Kawa is an implementation of the Scheme programming language that 
is built on top of the Java platform.  It is thus conveniently 
integrated with Java and benefits from this by having a compiler, 
optional static typing, and so on.  Kawa also serves as a 
framework for implementing other programming languages on the Java 
platform.  Included in Kawa is qexo, a partial implementation of 
XQuery in Java."

I actually have a slight preference for these :-), I find it more
factual than what you propose, but I’m happy either way.

Please use mirror://gnu.

I can amend the URL you, or you can send another patch.  Let me know!

Thanks,

The main difference is the emphasis. The suggested text emphasises 
the "framework" aspect of Kawa, whereas my text emphasise the 
"Scheme" aspect (with a short mention of the framework at the 
end). I don't know which emphasis the project desires, so I've 
Cced Per Bothner in case he has a preference. The text that I have 
used in the description is loosely taken from the Kawa home 
page[1].

The placement in scheme.scm makes the Scheme emphasis a natural 
choice. Compare with the description of Racket, which is also a 
framework for building programming languages, but our synopsis and 
description emphasise that it is an implementation of Scheme.

I've attached a patch with the updated URL.

Carlo

Per, note that the “suggested description” that Carlo refers to above
is the canonical description that GNU has for Kawa:

  http://cvs.savannah.gnu.org/viewvc/*checkout*/womb/gnumaint/rec/pkgblurbs.rec

We should change it if it doesn’t match the way you would present Kawa.

Let us know what you think!

Thanks,
Ludo’.

It just occurred to me that this new dependency on java.scm is probably
not desirable since it pulls in a lot of additional stuff.  I think we
should instead move Kawa to java.scm.  WDYT?

Anyway let’s also wait for Per’s reply.

Thanks,
Ludo’.

…or even to kawa.scm, just as we have clojure.scm.  I’ve been meaning to
move everything but the JDK bootstrap out of java.scm.
