New language V (on JVM)
Rahul — 2007-03-02 19:36:25
Hi,
First (alpha) release of V is available here
http://v-language.googlecode.com/files/v_0.001.jar
It is nothing more than a dialect of Joy at this point
(with some differences).
Only a few of the primitives are available:
[?(peek),??(show stack),.(define word)
!=, *,+,-,/,<,<=,=,>,>=,and,concat,cons,dip,dup,false
fold,i,map,not,or,pop,put,rolldown,rollup,swap,true
uncons,while]
More information is available here
http://v-language.googlecode.com/svn/trunk/v/status.txt
I hope to add an FFI for callout to java and a stack shuffling
operator soon.
Please do take a look, (I am just learning the theory and
implementing as I go along).

I love to see languages running on the JVM.
A couple of pointers just in case you're not aware:
1. Consider binding your implementation to the scripting framework:
http://java.sun.com/developer/technicalArticles/J2SE/Desktop/scripting/
https://scripting.dev.java.net/
2. Consider adding your implementation to the list of Languages for the JVM:

Cool, congrats on nice progress.

Curiosity: what's your goals?
Your definition syntax looks nice, by the way. Simple and clean...
Although I suppose one could complain that it's hard to visually
discern definitions from random blocks of code, I think it'll be
pretty rare to just have a random block of code.
Can definitions be constructed at runtime? Is "." a normal word or is it syntax?

Good idea, of course.
I've occasionally wondered what a concatenative language modeled to
take advantage of the JVM would look like. I recall that the JVM isn't
totally stack-centered; it has a lot of machinery for stack frames as
well.

Looks nice. This is probably a good way to learn.

dont have any goals (other than minimal syntax - (just '[' and ']'))
for now, I think I will let the language evolve and see where it goes.

thanks,

I agree it is hard to see definitions if it is inside an unformated
block of code but usually users format and delimit definitions
with empty lines comment headers and such,
I hope it would not prove to be a bad decision.

. is just a normal word.
