c# の code metricsは、visual studio で計測できますが、全srcの循環的複雑度をコマンドラインから一覧で生成したかった為、lizard を利用。

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, go, lua
  -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.

  -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 the 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
  --csv                 Generate CSV output as a transform of the default
                        output
  -H, --html            Output HTML report
  -m, --modified        Calculate modified cyclomatic complexity number ,
                        which count a switch/case with multiple cases as one
                        CCN.
  -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.
