具有unicode属性支持的Qt / C ++正则表达式库 [英] Qt/C++ regular expression library with unicode property support

问题描述

我使用C ++将应用程序从.Net框架转换为Qt。该应用程序广泛使用正则表达式unicode属性，即 \\ \\ p {L}，\p {M} 等等。我刚刚发现QRegExp类不支持这个东西（lookbehinds等）。

任何人都可以推荐一个C ++正则表达式库：

• 支持unicode属性


• 在其他方面（即\w匹配超过ASCII字符）


• 作为奖励，支持后退。

请不要指向维基百科的文章;我不相信。该文章说，QRegExp支持unicode属性。除非我真的做错了事，否则不会。我正在寻找一个实际上在项目中使用unicode属性和regex库的人。

ICU是一个成熟，广泛使用的
C / C ++ 和提供
的Java库。
软件应用程序的Unicode和全球化支持。

• 根据非限制性开源许可证发布


• ...


• 正则表达式：ICU的正则表达式完全支持Unicode
  ，同时提供非常有竞争力的
  性能。

它还与 Boost 兼容，请参阅这方面的声明。 / p>

I'm converting an application from the .Net framework to Qt using C++. The application makes extensive use of regular expression unicode properties, i.e. \p{L}, \p{M}, etc. I've just discovered that the QRegExp class lacks support for this among other things (lookbehinds, etc.)

Can anyone recommend a C++ regular expression library that:

• Supports unicode properties
• Is unicode-aware in other respects (i.e. \w matches more than ASCII word characters)
• As a bonus, supports lookbehinds.

Please don't point me to the wikipedia article; I don't trust it. That article says that QRegExp supports unicode properties. Unless I'm really doing something wrong, it doesn't. I'm looking for someone actually using unicode properties with a regex library in a project.

解决方案

ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications.

• released under a nonrestrictive open source license
• ...
• Regular Expression: ICU's regular expressions fully support Unicode while providing very competitive performance.

It's also compatible to Boost, see their statement in this regard.
