SQLiteCpp Doxygen Guide

For general style rules, see AGENTS.md and sqlitecpp-coding-standards.

Scope

• Doxygen runs on both include/ and src/ (see Doxyfile).
• Public API must be documented in headers.
• Source files still use Doxygen file headers.

Basic Example (Format Only)

/**
 * @file    Example.h
 * @ingroup SQLiteCpp
 * @brief   One-line summary of the file.
 */
class SQLITECPP_API Example
{
public:
    /**
     * @brief Do the thing.
     * @param[in] aValue  Value to use
     * @return Result value
     * @throw SQLite::Exception in case of error
     */
    int doThing(int aValue);
};

Keep the full MIT license block in real file headers.

Canonical Examples (Use These)

• File header + class + methods: include/SQLiteCpp/Database.h
• File header in src/: src/Database.cpp

File Header Rules

• Keep @file, @ingroup, @brief.
• Keep the MIT license block and copyright line.
• Keep #pragma once in headers.
• Match the existing header of the file you edit.

API Comment Rules

• @brief for every public class/method.
• @param[in|out] for each parameter.
• @return for non-void return values.
• @throw SQLite::Exception for throwing APIs.
• Use @note/@warning only when needed.
