一个类似的方法已经被JParseTree (JRuby的一个分析树端口)所采用，现在JRuby一部分额外软件包(JRuby Extras)提供了常用Ruby类库的JRuby端口。

A similar approach is already used by JParseTree, a port of ParseTree that works on JRuby, now a part of JRuby Extras which provides JRuby ports of popular Ruby libraries.

因为可以使用类似语法分析树(ParseTree)的通用方法来对Ruby代码进行分析并获得抽象语法树(Abstract Syntax Tree)，所以在Ruby历史上的一定时期内，纯ruby语法分析器的缺失被忽视了。

A lack of a pure Ruby parser has been negligible for some time in Ruby's history, since getting the Abstract Syntax Tree (AST) of some Ruby code was possible with utilities such as ParseTree.
