介绍一个类似Python和Ruby的新型脚本语言

这是一个支持动态类型的脚本语言，支持函数式编程和prototype based面向对象的OO开发。这个语言同Java可以无缝衔接：可以容易的访问Java的类，同时可以被Java的代码调用。

同Python、Ruby和Groovy相比，这个语言的语法相对更接近Java。所以熟悉Java的朋友学习起来很容易。

这个动态类型的脚本语言可以极大地加快你的开发速度，让你可以轻松完成开发任务。

下面是一个用Swing类库的计算器程序的示范程序。


运行方法:
(1) 你必须有JRE 1.6或者1.7已经安装
(2) 下载OrangeScript.jar
wget http://www.stonezhong.net/orangescript/OrangeScript.jar
(3) 下载计算器源码
wget http://www.stonezhong.net/orangescript/contents/examples/calculator.os
(4) 运行
java -classpath OrangeScript.jar orangeScript.parser.Main -file calculator.os

没搞懂是什么语言

[libralibra]

jython不是就可以调用java的类,还用的是python的语法吗?

OrangeScript......

fun main(args : Array<String>) { if (args.size == 0) { println("Please provide a name as a command-line argument") return } println("Hello, ${args[0]}!") } http://kotlin.jetbrains.org/

楼主的英文有待提高！建议重新打磨一下文档！ Variables must be declared before it can be referenced, reference a undeclared variable is a runtime error. 例如这一句。
