类名称：Ruby
方法名：parse

Ruby.parse介绍

[英]Parse the script contained in the given input stream, using the given filename as the name of the script, and return the root Node. This is used to verify that the script syntax is valid, for jruby -c. The current scope (generally the top-level scope) is used as the parent scope for parsing.
[中]使用给定的文件名作为脚本名，解析给定输入流中包含的脚本，并返回根节点。这用于验证jruby-c的脚本语法是否有效。当前作用域（通常是顶级作用域）用作解析的父作用域。
