[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
- 不包含代码注释的代码行数
- CCN 代码的复杂度，也就是分支复杂度
- token的个数（关键字，标示符，常量，标点符号，操作符)
- 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
- 不需要头文件全部指定（宏展开可能有失偏颇）
- 能够同时统计代码量和代码复杂度
- 能够产生和cppNCSS相同的报告
缺点
- c／c++的三字符组和双字符组
- c／c++的代码预处理和宏扩展没有实现
- c++的一些模版
对应的可以选择的参数

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.ws
positional 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 LANGUAGES
List the programming languages you want to analyze. if
left 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 bigger
than it will generate warning
-f INPUT_FILE, --input_file INPUT_FILE
get a list of filenames from the given file
-L LENGTH, --length LENGTH
Threshold for maximum function length warning. The
default value is 1000. Functions length bigger than it
will generate warning
-a ARGUMENTS, --arguments ARGUMENTS
Limit for number of parameters
-w, --warnings_only Show warnings only, using clang/gcc's warning format
for printing warnings.
http://clang.llvm.org/docs/UsersManual.html#cmdoption-
fdiagnostics-format
--warning-msvs Show warnings only, using Visual Studio's warning
format for printing warnings.
https://msdn.microsoft.com/en-us/library/yxkt8b26.aspx
-i NUMBER, --ignore_warnings NUMBER
If the number of warnings is equal or less than the
number, the tool will exit normally; otherwise, it
will generate error. If the number is negative, the
tool exits normally regardless of the number of
warnings. Useful in makefile for legacy code.
-x EXCLUDE, --exclude EXCLUDE
Exclude files that match this pattern. * matches
everything, ? matches any single character,
"./folder/*" exclude everything in the folder
recursively. Multiple patterns can be specified. Don't
forget to add "" around the pattern.
-t WORKING_THREADS, --working_threads WORKING_THREADS
number of working threads. The default value is 1.
Using a bigger number can fully utilize the CPU and
often faster.
-X, --xml Generate XML in cppncss style instead of the tabular
output. Useful to generate report in Jenkins server
-H, --html Output HTML report
-m, --modified Calculate modified cyclomatic complexity number
-E EXTENSIONS, --extension EXTENSIONS
User the extensions. The available extensions are:
-Ecpre: it will ignore code in the #else branch.
-Ewordcount: count word frequencies and generate tag
cloud. -Eoutside: include the global code as one
function. -EIgnoreAssert: to ignore all code in
assert. -ENS: count nested control structures.
-s SORTING, --sort SORTING
Sort the warning with field. The field can be nloc,
cyclomatic_complexity, token_count, p#arameter_count,
etc. Or an customized field.
-T THRESHOLDS, --Threshold THRESHOLDS
Set the limit for a field. The field can be nloc,
cyclomatic_complexity, token_count, parameter_count,
etc. Or an customized file. Lizard will report warning
if a function exceed the limit
-W WHITELIST, --whitelist WHITELIST
The path and file name to the whitelist file. It's
'./whitelizard.txt' by default. Find more information
in README.
