vs2010代码指标的延伸/扩展点在哪里？

Question

我想扩展 2010 年静态代码分析指标（主要是修复它，以便汇总是最大值而不是总和）。扩展点在哪里？它是某处的 MEF 组件吗？

Answer 1

我不确定 VS 2010 指标是否有任何扩展点。

或者，您可以选择附带 82 代码指标 的 NDepend，定义阈值就像这样简单编写一个简短的 针对 LINQ 查询 (CQLinq) 的代码规则，例如：

warnif count > 0 from m in Application.Methods where 
m.NbLinesOfCode > 30 || m.CyclomaticComplexity > 10
select new { m, m.NbLinesOfCode, m.CyclomaticComplexity }

您还可以查找像默认 CQLinq 代码规则一样的趋势： 避免使复杂方法均匀更复杂（源CC）

// <Name>Avoid making complex methods even more complex (Source CC)</Name>
// To visualize changes in code, right-click a matched method and select:
//  - Compare older and newer versions of source file
//  - Compare older and newer versions disassembled with Reflector

warnif count > 0 
from m in JustMyCode.Methods where
 !m.IsAbstract &&
  m.IsPresentInBothBuilds() &&
  m.CodeWasChanged()

let oldCC = m.OlderVersion().CyclomaticComplexity
where oldCC > 6 && m.CyclomaticComplexity > oldCC 

select new { m,
    oldCC ,
    newCC = m.CyclomaticComplexity ,
    oldLoc = m.OlderVersion().NbLinesOfCode,
    newLoc = m.NbLinesOfCode,
}

您还可以编写建议的代码指标，以定义您自己的代码指标，如CRAP 方法代码指标：

// <Name>C.R.A.P method code metric</Name>
// Change Risk Analyzer and Predictor (i.e. CRAP) code metric
// This code metric helps in pinpointing overly complex and untested code.
// Reference: http://www.artima.com/weblogs/viewpost.jsp?thread=215899
// Formula:   CRAP(m) = comp(m)^2 * (1 – cov(m)/100)^3 + comp(m)
warnif count > 0
from m in JustMyCode.Methods

// Don't match too short methods
where m.NbLinesOfCode > 10

let CC = m.CyclomaticComplexity
let uncov = (100 - m.PercentageCoverage) / 100f
let CRAP = (CC * CC * uncov * uncov * uncov) + CC
where CRAP != null && CRAP > 30
orderby CRAP descending, m.NbLinesOfCode descending
select new { m, CRAP, CC, uncoveredPercentage = uncov*100, m.NbLinesOfCode }
