About openharmony-cpp
openharmony-cpp is a skill for writing, refactoring, and reviewing C++ code under OpenHarmony conventions. It brings together platform-specific naming, formatting, header, and secure-coding rules.
Key features
- 01OpenHarmony naming and formatting rules
- 02Header and include guidance
- 03Input validation requirements
- 04Memory and bitwise safety rules
Use cases
- 01Generate classes or modules to OpenHarmony conventions
- 02Clean up legacy C++ code
- 03Review code against the conventions

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
.cppand.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
#ifndefguards. #pragma once is FORBIDDEN. - Includes: Prefer
#includeover forward declarations to prevent hidden dependencies. - Details: See headers_scopes.md.
3. Critical Security Requirements
- Input Validation: All external data must be validated before use (indices, sizes, loops).
- Memory Safety: Pointers must be set to
nullptrimmediately after deletion. - Bitwise: Only on unsigned types.
- Details: See secure_coding.md.
Usage Guide
When to use
- New Code: Generating new classes or modules.
- Refactoring: Cleaning up legacy code.
- Review: Checking code against OpenHarmony standards.
Reference Map
- naming_formatting.md: Naming conventions (g_, _), braces (K&R), line length.
- secure_coding.md: Input validation, integer safety, memory management, prohibited functions.
- class_function_design.md: Constructors, inheritance, modern C++ (nullptr, const), function size.
- headers_scopes.md: Header guards, namespaces, include rules.
