vagr9k / clang-tidy-linter

A Visual Studio Code extension to lint code by clang-tidy.

Clang Tidy Linter

This extension uses clang-tidy to lint C/C++ files.

This extension is in a very early stage of development. You will need to do some configuration before you can use it. But this extension is still kind of "usable".

Features

Basic diagnostic(linter) and quick fixes for the C/C++ source files with the clang-tidy.

Requirements

As for now you have to download/compile the clang-tidy executable. Maybe executables will be shipped with this extension in the future. The download link for official prebuilt binaries is http://releases.llvm.org/download.html.

Extension Settings

You may need to modify some default settings to get this extension to work for now.

clangTidy.executable: You need to manually set this to your clang-tidy executable file.

clangTidy.systemIncludePath: If you use the downloaded prebuilt binaries, it may fail to find some system headers. So put the system include paths here.

clangTidy.lintLanguages: What languages do you want to lint?

clangTidy.extraCompilerArgs: Extra arguments that pass to the compiler (not clang-tidy).

clangTidy.headerFilter: Value for -header-filter command line argument.

clangTidy.args: Additional arguments to pass to clang-tidy

If you want to configure the checks of clang tidy, create a .clang-tidy file in your working directory (please refer to the clang-tidy's document for detail).

Known Issues

Source files can only be lint when you save or open it.

You have to modify clangTidy.extraCompilerArgs setting if your C/C++ project has custom include paths.

I'm a beginner to vscode extension development, so if you have any suggestions, don't hesitate to post issues and/or pull requests.

Road Map (TODOs)

1. Refactor server.ts, it is now in a very bad structure (with lots of functions and global variables)

2. Write tests

3. Support for on-the-fly linting (if possible)

4. Support for custom include paths through settings and by reading .vscode/c_cpp_properties.json

5. Ship clang-tidy binaries

Know Issues

• When using -p compile_commands.json, saving a header or opening a header file for the first time can clear existing quick fixes for that file.
  • To regenerate the fixes, touch a cpp file which includes that header file.
  • compile_commands.json can be generated from CMake when CMAKE_EXPORT_COMPILE_COMMANDS is on.
