ragel

The language is parsed by a parser written using the Ruby library Ragel.

这门语言使用以ruby类库ragel编写的解析器进行解析。

However, a state machine can still be better if it is small enough or in situations where it would be appropriate to use something like Ragel to generate it for you.

不过，当状态机足够小或者在一些情况下，比如适合用Ragel之类地东西来产生它时，状态机仍是更好地选择。
