# C++ Header File Template Generator Generate header files following Google C++ Style Guide conventions. ## Usage Provide: class name, namespace, and file path to generate a compliant header. ## Template ```cpp // Copyright [year] [copyright holder] // // Licensed under the Apache License, Version 2.0 (the "License"); // you may not use this file except in compliance with the License. #ifndef [PROJECT]_[PATH]_[FILENAME]_H_ #define [PROJECT]_[PATH]_[FILENAME]_H_ // C system headers (if needed) // #include <sys/types.h> // C++ standard library headers #include <memory> #include <string> #include <vector> // Other library headers // #include "other/library.h" // Project headers // #include "project/base.h" namespace [namespace] { // Forward declarations (avoid when possible) /// Brief description of the class. /// /// Detailed description if needed. Include: /// - Purpose and responsibilities /// - Thread safety guarantees /// - Example usage (for complex classes) class [ClassName] { public: // Types and type aliases using ValueType = int; // Static constants static constexpr int kDefaultSize = 100; // Factory functions (if needed) static std::unique_ptr<[ClassName]> Create(); // Constructors [ClassName](); explicit [ClassName](int value); // Rule of five - be explicit about copy/move [ClassName](const [ClassName]&) = default; [ClassName]& operator=([const ClassName]&) = default; [ClassName]([ClassName]&&) noexcept = default; [ClassName]& operator=([ClassName]&&) noexcept = default; // Destructor ~[ClassName](); // Public methods void Process(); // Accessors and mutators int value() const { return value_; } void set_value(int value) { value_ = value; } protected: // Protected members (only if needed for inheritance) private: // Private methods void InternalHelper(); // Data members (always private for classes) int value_ = 0; std::string name_; }; } // namespace [namespace] #endif // [PROJECT]_[PATH]_[FILENAME]_H_ ``` ## Include Guard Format Convert path to uppercase with underscores: | File Path | Guard | |-----------|-------| | `foo/bar/baz.h` | `FOO_BAR_BAZ_H_` | | `src/http/parser.h` | `SRC_HTTP_PARSER_H_` | | `my_project/utils.h` | `MY_PROJECT_UTILS_H_` | ## Struct Template For passive data with public members and no invariants: ```cpp namespace [namespace] { /// Brief description. struct [StructName] { int field_one; // No trailing underscore for structs std::string field_two; float field_three = 0.0f; // Default values OK }; } // namespace [namespace] ``` ## Include Order 1. Related header (for `.cc` files) 2. Blank line 3. C system headers (`<unistd.h>`) 4. Blank line 5. C++ standard library (`<string>`, `<vector>`) 6. Blank line 7. Other libraries 8. Blank line 9. Project headers Each section sorted alphabetically.
