Finally a standard language for the Java platform
URL: ABCL

ABCL is an almost complete (99.58%) Common Lisp implementation for the Java platform. ABCL mixes elegantly the power of Lisp while exposing the rich set of Java APIs. If your project needs a dynamic language or should be based on international standards, you should evaluate it. ABCL is still young but is progressing very quickly. We're currently porting a project, and ABCL gives us the opportunity to keep the core while redesigning the GUI. ABCL is distributed under the GNU GPL with the special linking exception so it is appropriate for any type of project.

Re: Finally a standard language for the Java platform
Does it have the same (extremely bad) 'Lots of Silly Parentheses' Lisp has?Re: Finally a standard language for the Java platform
Sorry but there is Java.Fine if you have others, but I do not see the need.
I prefer the power of Java.
Re: Finally a standard language for the Java platform
It depends on the kind of problem you have. I have a little experience with Prolog (have written a few Prolog compilers for java) and there are certain problems Java is bad at: backtracking for example.So there is no 'one shoe fits all' language.

You forgot to mention that it stands for Armed Bear Common Lisp. "The right of the people to keep and arm bears shall not be infringed!"

Of course, because this is common lisp. One parenthesis to open an expression, one to close it.
BTW, parenthesis are really not a problem because your code is cleanly indented and so perfectly readable. But this clean syntax gives you a kind of power you won't get in any other programming language, not even in Forth or Prolog. Of course, other programming languages have also very interesting features and Lisp has some drawbacks. But the Lisp syntax is really a good thing.

Actually there is more than one. Most flexible languages will allow libraries to do those tasks.
For Lisp all problems must ressemble a list of some kind (not all true but close). For Prolog, the approch is with predicate. So from language to language, the way to express the problem is different, but I have never met a problem I could not solve with Java, Lisp is also quite limitless, Prolog is limited.
So yes there is "one shoe fits all", Java certainly is.
Saving a few lines of code in another language does not make it more fit.
Re: Finally a standard language for the Java platform
There are also several high quality Scheme implementations for the JVM.For example: http://sisc.sourceforge.net/

Re: Finally a standard language for the Java platform
There is a lot of interesting implementations of programming languages for the JRE, SISC being one of them. But my post was more about standards than implementations.Concerning Scheme, the standard (IEEE) is obsolete and R5RS is not a "standard". That doesn't mean you should not used it, after all Java is not a standard either.

Again this boring flawed argument.
Java is much more standard than Lisp as never been or ever will be. There is many Lisp, so where is the standard. Java is unique, so what is standard ? A stamp that means nothing.
Finally?
Isn't Java a standard language for the Java platform?Just thinking about writing code in anything approaching Lisp makes me cringe.

Java is turing complete language.. So everything can be build with java. But it doesn`t make java the best solution for every problem. If you have never used another language you have no right to speak.

Again.. java is turign complete, but so is c. Do you want to tell me you would wouldn`t have a problem using c instead of java? There are reasons some languages are better at some problems than others. There are problems that are better expression in Prolog/Lisp (haven`t much experience with Lisp) than Java.

Prolog is turing complete so every program that can be written in Java, can be written in Prolog. The question is if you want to do that. There are a lot of problems I would never ever try to solve in prolog... but there are some problems that are hell of a lot easier in Prolog than in Java

I don`t agree. Java is a nice language and you can build everyting in it. But there are certain problems that could be expressed better in Prolog. The power should not be a single language, but the integration of multiple languages.

It can, for certain problems java is a drag.. and Prolog is a gift of God himself.. But it doesn`t make java or Prolog the best language for all problems. This is something you need to understand.

No, it is not. No national/international organization has stamped/blessed it.

Give it a serious try and you will love it (and later just like it). As a programming language.
Re: Finally?
Sun's stewardship of the Java platform might take the form of a benevolent dictatorship, but it works. I really don't see what benefit would be gained by having IEEE or ECMA or anybody else giving Java their "blessing".
