码工魄-代码统计

不知道社区各位,是否知道这样一个工具.

统计一个工程的源代码,对类库中方法/类的使用情况进行统计.

比如 java项目,
java.util.LinkedList 类, #### 次/千行代码
java.util.LinkedList.removeFirst() 方法, ####次/千行代码

最好能识别借口,父类,多态.

如果没有以上工具的话,打算用java做一个.
思路是使用正则表达式和语法分析( JavaCC)

这个代码统计的目的,主要是找出实际项目中最常用的20%的知识.

ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. Finally, it preverifies the processed code for Java 6 or for Java Micro Edition.

Java Gems are general purpose utilities for Java. Yes, Java Gems are those simple code snippets copied again and again from one project to another, often from your private project to several work projects, those small things you cannot find in java.util and its subpackages, but you cannot live without them.

ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR provides excellent support for tree construction, tree walking, translation, error recovery, and error reporting. There are currently about 5,000 ANTLR source downloads a month.
