Coding Guidelines

• This project contains a .prettierrc configuration file to help your editor contribute consistent code. For vscode, use this extension.
• We use conventional commits to help with automatic semantic versioning. Please ensure your commit messages follow this format.

Helpful commands

• npm run bootstrap to bootstrap the project.
• npx lerna add <dep> packages/<project> [--dev] to add a dep (--dev makes it a dev dep).
• npm run build builds all packages.
• npm run clangffi runs clangffi (remember to build first).
• npm run generate-dogfood re-generates our libclang bindings using libclang-bindings (ourself).
