English(EN) Do Grep and AST Agree on Which Functions Are Dead Code?

Python 死代码检测:AST 优于 Grep

一位开发者比较了两种识别 Python 中死代码的方法:Grep 和抽象语法树 (AST) 解析。使用正则表达式的 Grep 方法比 AST 方法标记的潜在死函数更少。AST 解析器正确识别了对 dunder 方法的隐式调用,并区分了实际函数调用和文档字符串中的提及,而 Grep 方法在这方面存在困难。然而,这两种方法都未能检测到通过外部框架(MCP tools)调用的函数,导致这些情况下出现死代码的误报。 AI

影响 强调了静态代码分析工具的局限性,影响了开发者的生产力和代码质量。

    Grep 和 AST 在判断哪些函数是死代码方面是否一致?

    <p>I wanted a quick dead-code pass over the Python files in my <code>my-git-manager</code> repo (<code>server.py</code>, <code>reply_comments.py</code>, <code>publish_devto.py</code>, <code>git_commit.py</code>, and three scripts under <code>scripts/</code>) and had two options s…
