OpenHarmony C++ Coding Skills

Core Mandates (Common Pitfalls)

These rules are strictly enforced in OpenHarmony and often differ from general C++ projects.

1. Strict Naming & Formatting

• Extensions: Always use .cpp and .h.
• Files: Filenames must match class names (Unix-like, e.g., my_class.cpp).
• Variables: Global vars must start with g_ (e.g., g_config). Class members must end with _ (e.g., value_).
• Braces: K&R Style is mandatory (opening brace on the same line).
• Details: See naming_formatting.md.

2. Header Management

• Guards: Use #ifndef guards. #pragma once is FORBIDDEN.
• Includes: Prefer #include over forward declarations to prevent hidden dependencies.
• Details: See headers_scopes.md.
