cocoa 下的正则表达式框架

RegexKit is an Objective-C framework for regular expressions:

  • Support for Mac OS X Cocoa and GNUstep. Mac OS X 10.4 or later required.

  • Mac OS X Universal Binary, including 64-bit support on Mac OS X 10.5.

  • No sub-classing required. Seamlessly adds regular expression support to all NSArray, NSData, NSDictionary, NSSet, and NSString Foundation objects with a rich set of Objective-C category additions.

  • Unicode enabled. Full Unicode support for NSString objects.

  • Extensive, high quality documentation.

  • Full source code with a BSD license.

  • Uses the BSD licensed PCRE Perl Compatible Regular Expressions library for the regular expression engine.


Tuned for high performance, including such features as:

  • Caches the compiled form of the regular expression for speed.

  • Multithreading safe, including multiple reader, single writer multithreaded access to the compiled regular expression cache.

  • Makes minimal use of heap storage (ie, malloc() and free()), instead allocating most temporary buffer needs dynamically from the stack.

  • Uses Core Foundation directly on Mac OS X for additional speed.


Includes support for Mac OS X 10.5 Leopard:

  • 64 bit support. Pre-built for ppc, ppc64, i386, and x86_64.

  • Garbage Collection enabled. Complete support for Leopards Garbage Collection feature.

  • Integrated Xcode 3.0 documentation. Get real time API information via the Research Assistant.

  • Collection of instruments for Instruments.app.

  • RegexKit specific DTrace probe points.

除了使用正则表达式匹配字符、数组以外,还可以使用NSPredicate做过滤查找。待续...
