Contributing to pret/pokeheartgold

• Code Formatting

This document provides a synopsis and loose guidelines for how to contribute to this project. It is a work in progress. Maintainers should expand this document.

Code Formatting

This repository includes an opinionated clang-format specification to ensure that we maintain a common code style. For convenience, a pre-commit hook is also provided in .githooks which will run clang-format against any staged changes prior to executing a commit.

Requirements

• clang-format@17 or newer

Usage

To set up the pre-commit hook:

git config --local core.hooksPath .githooks/

To run the formatter on the full source tree:

./format.sh

Nonmatching functions

clang-format does not recognize the syntax for inline asm that is required by mwccarm, so it should be disabled for non-matching functions specifically. clang-format accepts directives via comments of the form // clang-format [on|off]. Example:

#ifdef NONMATCHING
void func() {
    // ...
}
#else
// clang-format off
asm void func() {
    push {lr}
    // ...
    pop {pc}
}
// clang-format on
#endif // NONMATCHING
