# Tips for developing Dawn code

- Set up your IDE to use clangd:
  - Set `"custom_vars": { "checkout_clangd": True }` in `.gclient`
    (or just use `standalone-maximal.gclient`).
  - Point your IDE to the binary at
    `third_party/llvm-build/Release+Asserts/bin/clangd`.
  - Use the compile commands from `out/YourBuildDir/compile_commands.json`.
    These are generated by `gn gen`.
- Build/run as much stuff as possible locally, to avoid finding bugs on CQ:
  - Use `scripts/standalone-maximal.gclient` instead of `standalone.gclient`.
  - Use `scripts/args-maximal.gn` as reference for building as much as possible
  - Run `gn gen --check` to locally run the check that C++ includes match the
    build files.
