This article will not discuss the AST in any detail here, except to say that when the extension needs to add new elements to the generated source it does so by calling methods on the AST objects. 本文在这里并不讨论关于AST的任何细节，除非当扩展需要向生成的代码添加新元素时，才会涉及到一些。通过访问AST的方法来做到这一点。 - 2
Tools, based on ParseTree, already exist, such as Ruby2Ruby which can turn an AST back into Ruby source code; useful if a tool wants to modify an AST and then output it as Ruby source. 已有的基于分析树的工具，比如Ruby2Ruby可以把AST转换成Ruby源代码；如果某工具想修改AST并输出为Ruby源代码，这很有用。 - 3
Of course, you could just deal with things as Strings and Lists and ignore the AST part of the world, picking apart the returned Strings and Lists and re-parsing them into AST elements. 当然，您可以只与String和List打交道，而忽略ast部分，拆开返回的String和List，并重新将它们解析成ast元素。
