声纳-LOC&圈复杂度 [英] Sonar -LOC & Cyclomatic complexity

问题描述

Sonar如何计算软件指标，尤其是LOC和圈复杂度?它使用任何特定的工具吗?如果是的话，也请给出名字.

How does Sonar calculates software metrics particularly LOC and cyclomatic complexity? Does it uses any particular tools? IF yes, please also give the names.

推荐答案

对于每种受支持的语言，"squid"插件用于解析源代码并确定一些基本指标，例如LOC和复杂性.复杂度的计算方式因插件而异.

For each supported language, a "squid" plugin is used to parse the source code and determine some base metrics such as LOC and complexity. How the complexity is calculated varies based on the plugin.

例如，这是JavaScript插件的源代码文件:

For example, here's the source code files for the JavaScript plugin: https://github.com/SonarCommunity/sonar-javascript/tree/master/javascript-squid/src/main/java/org/sonar/javascript/metrics In this case, the complexity is calculated in the plugin itself using a very simple formula.

以下是C#支持的相同类集:

And here is the same set of classes for the C# support: https://github.com/SonarCommunity/sonar-dotnet/tree/master/sonar/csharp/sonar-csharp-squid/csharp-squid/src/main/java/com/sonar/csharp/squid/metric

但是，指标的创建可以由任何插件完成，因此，如果您想补充数据或以其他方式显示数据，则可以编写自己的插件.

The creation of metrics, though, can be done by any plugin, so you could write your own plugin if you wanted to supplement the data, or display the data in a different way.
