C解析乐趣 [英] C parsing fun
问题描述
Helo ppl！
在工作中，我被赋予了根据我老板的概念制作脚本来分析C ++代码
的任务。要做到这一点，我需要以某种方式在Python中表示C ++
代码结构。我读了Yapps的文档，pyparsing
和其他类似的东西，然后我提出了一个非常简单的想法。我b $ b意识到括号中的代码几乎就像一个Python列表，除了我
必须用方括号替换大括号并包围
剩余带引号的东西。这个过程不会调用递归或节点
对象，只有纯粹的字符串操作，所以我相信它真的很快。
最后我可以通过调用eval得到结果列表（ ）用
字符串。
例如当我需要解析类定义时，我只需要
寻找包含模式* class *的列表项，下一个
项将是该类的内容作为另一个列表。

（包括测试脚本[test.py]）
Helo ppl!
At the job I was given the task to make a script to analyze C++ code
based on concepts my boss had. To do this I needed to represent C++
code structure in Python somehow. I read the docs for Yapps, pyparsing
and other stuff like those, then I came up with a very simple idea. I
realized that bracketed code is almost like a Python list, except I
have to replace curly brackets with squared ones and surround the
remaining stuff with quotes. This process invokes no recursion or node
objects, only pure string manipulations so I believe it''s really fast.
Finally I can get the resulting list by calling eval() with the
string.
For example when I need to parse a class definition, I only need to
look for a list item containing the pattern "*class*", and the next
item will be the contents of the class as another list.

推荐答案
，最棒的是该算法可以与任何使用括号构造代码的
语言一起使用，例如PHP和许多
其他。
and the great thing is that the algorithm can be used with any
language that structures the code with brackets, like PHP and many
others.

是的，这是一个不错的解决方案
有时候它还不够（赢了'''无论如何你需要更复杂的东西然后我会推荐
gccxml或者是它的python绑定：
http://www.language-binding.net/pygccxml/pygccxml.html
yes that''s a nice solution
sometimes it''s not enough though (won''t work on code obfuscated with
macros)
anyway if you need something more sophisticated then i''d recommend
gccxml or it''s python binding:

响应的Thx，Szabolcs！我已经尝试过了，但是没有b $ b设法让它上班。我试图解析的源是一个巨大的MSVC
7.1解决方案，包含大约38个项目，我相信代码是如此复杂，以至于它有太多不同的依赖关系和GCC只是
无法处理它们。顺便说一下，我对C ++编译器不是很熟悉，所以
也许是因为编译器配置错误，但我真的不知道... b $ b知道...

Thx for responding, Szabolcs! I''ve already tried that, but couldn''t
manage to get it to work. The source I tried to parse is a huge MSVC
7.1 solution containing about 38 projects, and I believe the code is
so complex that it has too many different dependencies and GCC just
can''t handle them. Btw I''m not deeply familiar with C++ compilers, so
maybe it was because of compiler misconfiguration, but I really don''t
know...
