什么是php好的解析器生成器? [英] What is a good parser generator for php?
问题描述
我需要解析一种小的迷你语言"，用户可以在我的网站上键入该语言.我想知道lex和jacc或antlr的对应版本对php世界有什么作用.
I need to parse a small 'mini language' which users can type on my site. I was wondering what the counterparts of lex and jacc or antlr are for the world of php.
推荐答案
我使用了用于PHP的LIME Parser生成器几年前，它已经成熟并且稳定.
I used LIME Parser generator for PHP a couple of years ago, and it was already mature and stable.
解析器生成器本身是用PHP编写的，在任何技术意义上都没有关系-因为我们仅要求生成的解析器使用PHP-但尽管如此，我仍然喜欢这个细节.这使我对用PHP编写软件感到抱歉;;)
The parser generator itself is written in PHP, which doesn't really matter in any technical sense - as we require only that the generated parser be in PHP - but I like this detail nonetheless. It makes me feel less apologetic about writing software in PHP ;-)
我应该添加:
-
在我写二手"的地方，说我玩过"会更准确.我还没有使用石灰编写任何生产代码.但是我没有理由不这样做.
Where I wrote "used" it would be more accurate to say that I "played with". I haven't written any production code using lime, yet. But I see no reason not to do so.
lime附带的计算器示例"使用tokenize()方法，该方法与lex的功能的真正替代品相去甚远.但是，如果您需要一个真正的令牌生成器，则应该可以在前端"上使用lex将令牌提供给后端"上的lime.
The "calculator example" provided with lime uses a tokenize() method which is very far from a real substitute for the power of lex. But if you need a real tokenizer it ought to be possible to use lex on the "front end" to feed tokens to lime on the "back end".
