General file style

  • General style guidelines -- like newlines at the end of file -- are linted for using pre-commit
  • The rules enforced are available in the repo's .pre-commit-config.yaml file.
  • You can install pre-commit locally with these instructions.
  • The linter may be run locally using pre-commit run --all-files. Additionally it can be installed as a commit hook with pre-commit install.

C++ coding style

Java coding style

  • Java code is auto-formatted using clang-format with these rules

Objective-C coding style

  • Objective-C code is auto-formatted using clang-format with these rules

  • The rules enforced are available in the repo's .swiftlint.yml file
