# Contributing new code

- Please do the following *before* sending a pull request:
  - Merge upstream code (if any) back into your own branch
  - Run formatters/linters

# Git

- TODO: tagging / versions
- TODO: branch stability / gitflow?

# Code style

- Formatting nitty-gritty is handled by clang-format/clang-tidy
- ASCII only
- When using libraries of which the header include order is important, make
  sure to separate the include statements using a blank line (clang-format may
  sort include statements, but does not sort across empty lines).

## CMakeLists specific

- Make sure list arguments (e.g. sources, libraries) given to commands (e.g.
  `target_sources`, `target_link_libraries`) are on separate lines. This makes
  resolving merge conflicts when multiple sources were added by different
  people to the same CMakeLists.txt easier.

# Documentation

- All documentation is written in U.S. English
- TODO

# Libraries

- External libraries should be included as Git submodules under the `lib/`
  subdirectory
- When adding new submodules, make sure to manually set the `branch` and
  `shallow` options in the [.gitmodules](./.gitmodules) file
