Doxygen不会生成任何文档

Question

这是我的lexer.hpp文件：

/**
 * \file
 * \brief Lexical analysis
 * \author Igor Zashchelkin
 *
 * Lexical analysis API for MyLisp.
 */

#ifndef LEXER_H
#define LEXER_H

#include <string>
#include <vector>

/**
 * \brief Used to link token (Token) with it's type.
 * \date June 29, 2018
 *
 * TokenNumber     - 12, 5.4, -200
 * TokenString     - "hello, world"
 * TokenBoolean    - true, false
 * TokenIdentifier - function name, variable name
 * TokenSeparator  - ( ) ,
 */

enum TokenType {
     TokenNumber /// \brief Tokens which store numeric data
    ,TokenString /// \brief Tokens which store symbolic data, that ends and starts at "
    ,TokenBoolean /// \brief Tokens which store only one state 1 or 0
    ,TokenIdentifier /// \brief Tokens which link to something (variable, function)
    ,TokenSeparator /// \brief Tokens which splits logical parts of code
};

/**
 * \brief Token's value type
 * \date June 29, 2018
 *
 * Simply, wrap of std::string
 */

typedef std::string TokenValue;

/**
 * \brief Minimal part of lexical analysis
 * \date June 29, 2018
 *
 * Structured pair of TokenType and TokenValue (aka std::string)
 */

class Token {
private:
    const TokenType type; /// \brief Token's type
    const TokenValue value; /// \brief Token's value
public:
    Token(TokenType type, std::string value); /// \brief Constructor

    const TokenType getType(); /// /brief Getter for type property
    const TokenValue getValue(); /// \brief Getter for value property
};

/**
 * \brief Lexical analysis API instance
 * \date June 29, 2018
 */

class Lexer {
private:
    std::string code; /// \brief Source code
public:
    Lexer(std::string code); /// \brief Constructor

    /**
     * \brief Tokenize source code
     * \date June 29, 2018
     *
     * Generate sequence of tokens (std::vector) from code property (std::string)
     */

    std::vector tokenize();
};

#endif //LEXER_H

一切都很好（这是我的想法），但是当我运行

doxygen src/lexer/lexer.hpp

Doxygen生成空文档。 怎么了？

Answer 1

您应该有一个doxygen配置文件（Doxyfile），可以使用doxygen -g生成默认版本。在Doxyfile中，您可以设置所需的选项。然后，您可以仅从doxygen中的doxygen Doxyfile开始doxygen。

即使使用OP所使用的设置，我也得到了文档（以及许多警告消息，例如：“警告：忽略lexer.hpp文件第2行中的未知标记`file'”，表明有些错误）。

另请参阅doxygen文档。
