Running clang-tidy

  • Add "checkout_clang_tidy": True to .gclient file in the custom_vars.
      "custom_vars": {
        "checkout_clang_tidy": True,
  • gclient sync

There should now be third_party/llvm-build/Release+Asserts/bin/clang-tidy

  • cd out
  • git clone

The Chromium build folder contains the tricium files used to run clang-tidy

Running clang-tidy over all the source can be done with:

cd ..
out/build/recipes/recipe_modules/tricium_clang_tidy/resources/ \
--base_path $PWD \
--out_dir out/Debug \
--findings_file all_findings.json \
--clang_tidy_binary $PWD/third_party/llvm-build/Release+Asserts/bin/clang-tidy \

--all can be replaced by specific files if desired to run on individual source files.
