Yoix

Yoix - Programming language

< >

Yoix is an open source programming language created in 2000 by Rich Drechsler and John Mocenigo.

#618on PLDB 23Years Old

In computer programming, Yoix is a high-level, general-purpose, interpreted, dynamic programming language. The Yoix interpreter is implemented using standard Java technology without any add-on packages and requires only a Sun-compliant JVM to operate. Initially developed by AT&T Labs researchers for internal use, it has been available as free and open source software since late 2000.. Read more on Wikipedia...


Example from hello-world:
import yoix.stdio.*; printf("Hello World");
Example from Wikipedia:
