Re: Belgian Clojure base meetup?
I have joined the Amsterdam Clojurians before, but live in Vroenhoven now (near Maastricht, relatively close to Liége).

Re: on lisp and scheme macros
Em 12/04/11 03:16, Razvan Rotaru escreveu: Wow. I didn't thought this was possible. You know, I have seen a lot of people saying that scheme macros are more "powerfull", citing the fact that scheme also has lisp macros, while it's not possible to do it the other way around. Of course it's possible. I think it's mostly like training wheels on a bike and the like: defmacro is some kind of atom macro system you can use to do anything you can imagine, but some things are hard to do, and the scheme system is just making the common cases easier to do right. I have been reading the Guile 2.0 documentation (very much worth a read, as it's the first Guile with a VM and other languages than Scheme, e.g. Emacs lisp) and I think this and that (and Clojure) show very well that good lisps is more a case of sensible defaults (Guile: very very easy to integrate in C; Clojure: JVM as an asset, immutable by default and mutability as an option...) than anything else that makes a lisp better or worse. You can basically do everything in every lisp, but defaults really matter. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Adding "Change History" To Clojure Modules
In that case I would suggest putting it on top of the file more
or less like this
with a lot of ;'s at the start. You could create a script to
update that automatically
from the CVS I suppose, and if you make sure it's autogenerated
and that it comes
from the CVS it gives a lot more insight for both sides. But
that's my opinion.
At least I wouldn't put it in the docstring.

Re: let binding ~'=
it is a macro with a syntax quote, so all symbols are
namespace-qualified. so = will actually be clojure.core/=
the ~' removes this namespace-qualification, so it is rendered as just =.

Re: Clojure Web Programming group?
I am playing a bit with shapado (open source stackoverflow clone in ruby, I made an Esperanto QA site with it at demandoj.tk) and maybe it's an idea to create a clojure webdev shapado thus creating a fun to use self-documenting system and using the wikipages etc to provide more information of all separate projects... For project specific stuff I think mailing lists are the best thing since sliced bread. However for newbie questions and documentation it gets messy quite quickly, so I think a QA site for all of the Clojure Webdev stuff might be nice.

Re: chinese character in hiccup
What do you get if you use the meta-line with GBK encoding? if that
gives the right output, it is an input problem (i.e. the input is not
UTF-8).

Re: database management: curing lock issues

Re: group tag for clojure newsgroup
True what said, but sometimes I filter things on subject instead of list as it is all the same for me (e.g. clojure and compojure-list on the same label) and there it can be useful as well. Now I have compojure (low-volume) and clojure (high-volume) split up and it's just not worth it for the seldom appearing compojure-mails, but to see it's a compojure-thing is useful still. If some want it, +1 for me as well.

Clojure on Go
I read this part... http://www.reddit.com/r/programming/comments/b3sb1/golisp_a_lisp_interpreter_in_go/ and thought, would someone be able to do that for clojure? (the Clojure in Clojure stuff might make this easier :)) Is this a weird idea? I like a lot of ideas in go, and it's speed, but Clojure is just some bits nicer. When we have clojure on go, we can have compiled clojure without java runtime and fast, can't we? It sure has advantages, and as a toy project it might be cool. And most of Clojure's code is in clojure anyway, so that eases porting I guess. And you can add go's concurrency features as another way to get things done :). -- Communication is essential.

Re: error reporting for macro expansion
In the example, you can find a reference to the actual macro (line and name) in the second part (Caused by:).

This means you can arrange another license for paying people if you want, this is what is done when dual-licensing. If you reuse things of other people however, this must be in consent with those licenses.

Re: Getting started with few Java knowledge
I am just clueless in CCW how to get it compiled nicely. It doesn't get you started with the files you need minimally to get it compiled correctly and I remain clueless on how to get it to work. And I get duplicated files probably because of eclipse works (include every compiled file in the project as it is in the same directory). I got lost there =x. At least I would like to see a basic workflow document about CCW, and better of course to have it nicely built in in Eclipse. I hope you understand what I mean... 2009/12/28 Laurent PETIT : > > 2009/12/28 Joop Kiefte >> >> [...] I think this works a lot nicer than CCW.

Re: Getting started with few Java knowledge
Thanks a lot! I think this works a lot nicer than CCW. I have made a
little script to do a checkout and rename for new projects and it
works brilliant.
Again, thanks a lot!

Getting started with few Java knowledge
Hello folks,
I have been learning a bit of Java at school a loong time ago
("programming basics"), when we were programming applets and I
outscored all others with ease as I was the only one who could program
already, and now I do android programming in Java, but I have never
ever made a normal Java project, so I feel I'm missing some essentials
to get started in Clojure when I want to create "stand-alone" apps.
Can some of you maybe help me getting started on a Clojure project,
e.g. the files I need to have to get it compiled nicely to a working
JAR-package? (I use eclipse with CCW, but explanations for emacs are
fine as well.) I have been looking online but I don't succeed well
with the instructions found out there, I think it assumes too many
knowledge of Java...
Thanks beforehand, I would really appreciate your help (and don't be
shy to make it verbose and full of hints ;))
