简介
MegaLinter 是一个多语言、多工具的集成代码检查工具，它能够通过一个统一的工作流来运行多个静态代码分析工具，从而提供全面的代码质量检查。
官网：https://megalinter.io/latest/
MegaLinter 的特点：
多语言支持：MegaLinter 支持多种编程语言，包括常见的如 C、C++、Java、Python、JavaScript 等，以及一些不太常见的语言。这使得它成为跨多个项目和团队的理想选择。
多工具集成：MegaLinter 集成了许多常用的静态代码分析工具，如 ESLint、Pylint、RuboCop、Checkstyle 等。通过 MegaLinter，我们可以在一个工作流中同时运行这些工具，减少配置和管理的复杂性。
全面的代码检查：MegaLinter 运行各种工具，并对代码库进行全面的代码质量检查。它可以检查代码规范、潜在的错误、安全漏洞、代码复杂度等等，帮助我们发现和解决潜在的问题。
体验
编写两个 js 文件
demo.js
cosole.log("nihao");
demo-2.js
console.log('nihao')
目录结构如下：
D:/apps-data/docker/megalinter/lint/
|- demo.js
|_ demo-2.js
启动镜像，开始检测
docker run --rm -v D:/apps-data/docker/megalinter/run/docker.sock:/var/run/docker.sock:rw -v D:/apps-data/docker/megalinter/lint:/tmp/lint:rw oxsecurity/megalinter:v7
其中 -v D:/apps-data/docker/megalinter/lint:/tmp/lint 将D:/apps-data/docker/megalinter/lint下存储的待测文件转储进 /tmp/lint
megalinter 将扫面 /tmp/lint 中的文件，并自动识别其语言，然后进行静态检查。
日志如下：

总结
- Megalinter 的 Docker 镜像包很大(9G多)，下载比较慢 。
- Megalinter 的结果生成在文件中，并不能拿来直接使用。
