[other] 代码量代码复杂度统计-lizard

lizard的可以用来统计下面的一些数据

1. 不包含代码注释的代码行数
2. CCN 代码的复杂度，也就是分支复杂度
3. token的个数（关键字，标示符，常量，标点符号，操作符)
4. 函数的参数个数

支持下列的一些语言

• C/C++ (works with C++14)
• Java
• C# (C Sharp)
• JavaScript
• Objective C
• Swift
• Python
• Ruby
• TTCN-3
• PHP
• Scala
• GDScript

优点

1. 不需要头文件全部指定（宏展开可能有失偏颇）
2. 能够同时统计代码量和代码复杂度
3. 能够产生和cppNCSS相同的报告

缺点

1. c／c++的三字符组和双字符组
2. c／c++的代码预处理和宏扩展没有实现
3. c++的一些模版

usage: lizard [options] [PATH or FILE] [PATH] ...lizard is an extensible Cyclomatic Complexity Analyzer for many programming
languages including C/C++ (doesn't require all the header files). For more
information visit http://www.lizard.wspositional arguments:paths                 list of the filename/paths.optional arguments:-h, --help            show this help message and exit--version             show program's version number and exit-l LANGUAGES, --languages LANGUAGESList the programming languages you want to analyze. ifleft empty, it'll search for all languages it knows.`lizard -l cpp -l java`searches for C++ and Java code.The available languages are: cpp, java, csharp,javascript, python, objectivec, ttcn, ruby, php,swift, scala, GDScript-V, --verbose         Output in verbose mode (long function name)-C CCN, --CCN CCN     Threshold for cyclomatic complexity number warning.The default value is 15. Functions with CCN biggerthan it will generate warning-f INPUT_FILE, --input_file INPUT_FILEget a list of filenames from the given file-L LENGTH, --length LENGTHThreshold for maximum function length warning. Thedefault value is 1000. Functions length bigger than itwill generate warning-a ARGUMENTS, --arguments ARGUMENTSLimit for number of parameters-w, --warnings_only   Show warnings only, using clang/gcc's warning formatfor printing warnings.http://clang.llvm.org/docs/UsersManual.html#cmdoption-fdiagnostics-format--warning-msvs        Show warnings only, using Visual Studio's warningformat for printing warnings.https://msdn.microsoft.com/en-us/library/yxkt8b26.aspx-i NUMBER, --ignore_warnings NUMBERIf the number of warnings is equal or less than thenumber, the tool will exit normally; otherwise, itwill generate error. If the number is negative, thetool exits normally regardless of the number ofwarnings. Useful in makefile for legacy code.-x EXCLUDE, --exclude EXCLUDEExclude files that match this pattern. * matcheseverything, ? matches any single character,"./folder/*" exclude everything in the folderrecursively. Multiple patterns can be specified. Don'tforget to add "" around the pattern.-t WORKING_THREADS, --working_threads WORKING_THREADSnumber of working threads. The default value is 1.Using a bigger number can fully utilize the CPU andoften faster.-X, --xml             Generate XML in cppncss style instead of the tabularoutput. Useful to generate report in Jenkins server-H, --html            Output HTML report-m, --modified        Calculate modified cyclomatic complexity number-E EXTENSIONS, --extension EXTENSIONSUser the extensions. The available extensions are:-Ecpre: it will ignore code in the #else branch.-Ewordcount: count word frequencies and generate tagcloud. -Eoutside: include the global code as onefunction. -EIgnoreAssert: to ignore all code inassert. -ENS: count nested control structures.-s SORTING, --sort SORTINGSort the warning with field. The field can be nloc,cyclomatic_complexity, token_count, p#arameter_count,etc. Or an customized field.-T THRESHOLDS, --Threshold THRESHOLDSSet the limit for a field. The field can be nloc,cyclomatic_complexity, token_count, parameter_count,etc. Or an customized file. Lizard will report warningif a function exceed the limit-W WHITELIST, --whitelist WHITELISTThe path and file name to the whitelist file. It's'./whitelizard.txt' by default.
