# C++ 代码分析
|
|
|
|
Doris支持使用[Clangd](https://clangd.llvm.org/)和[Clang-Tidy](https://clang.llvm.org/extra/clang-tidy/)进行代码静态分析。Clangd和Clang-Tidy在 [LDB-toolchain](/docs/install/source-install/compilation-with-ldb-toolchain)
|
|
中已经内置，另外也可以自己安装或者编译。
|
|
|
|
### Clang-Tidy
|
|
Clang-Tidy中可以做一些代码分析的配置,配置文件`.clang-tidy`在Doris根目录下。
|
|
|
|
### 在VSCODE中配置Clangd
|
|
|
|
首先需要安装clangd插件，然后在`settings.json`中编辑或者直接在首选项中更改插件配置。相比于vscode-cpptools，clangd可以为vscode提供更强大和准确的代码转跳，并且集成了clang-tidy的分析和快速修复功能。
|
|
在使用之前，先编译一次`be(RELEASE)`和`be-ut(ASAN)`，以生成对应的`compile_commands.json`文件。
|
|
|
|
```json
|
|
"clangd.path": "ldb_toolchain/bin/clangd", //clangd的路径
|
|
"clangd.arguments": [
|
|
"--background-index",
|
|
"--clang-tidy", //开启clang-tidy
|
|
"--compile-commands-dir=doris/be/build_Release/",
|
|
"--completion-style=detailed",
|
|
"-j=5", //clangd分析文件的并行数
|
|
"--all-scopes-completion",
|
|
"--pch-storage=memory",
|
|
"--pretty",
|
|
"--query-driver=ldb_toolchain/bin/*" //编译器路径
|
|
],
|
|
"clangd.trace": "output/clangd-server.log"
|
|
```
