How to Preserve A Comment In an Example In Doxygen?

To preserve a comment in an example in Doxygen, use the tag before and after the comment. This will display the text exactly as it is written without any formatting or special characters being interpreted. This can be useful when you want to include code snippets or special characters in your comments without them being modified by Doxygen.

What is the process for controlling example visibility in Doxygen?

To control the visibility of examples in Doxygen, you can use the \example command in your source code comments.

Here is the process for controlling example visibility in Doxygen:

1. Add an \example command before each example code block in your source code comments. This command specifies the name of the example and sets its visibility level. You can use the following visibility levels: \example private: The example will not be included in the documentation. \example protected: The example will be included in the documentation, but marked as protected. \example public: The example will be included in the documentation and marked as public.
2. Specify the visibility level for each example according to your requirements.
3. Enable the EXAMPLE_PATH configuration option in the Doxygen configuration file to specify the directories where example files are located. This will allow Doxygen to include and display the examples in the documentation.
4. Generate the HTML documentation using the doxygen command. The examples with the specified visibility levels will be included in the documentation according to the settings you have defined.

By following these steps and using the \example command with the appropriate visibility level, you can control the visibility of examples in Doxygen documentation.

What is the importance of linking within examples in Doxygen?

Linking within examples in Doxygen is important for providing additional context and understanding for the reader. By including links to related functions, classes, or other parts of the documentation, users can easily navigate between different sections and learn more about the code and its relationships. This can help in clarifying complex concepts, reinforcing understanding, and improving overall comprehension of the software being documented. Additionally, linking within examples can also make the documentation more interactive and engaging for users, allowing them to explore related information and dive deeper into specific topics.

How to organize multiple examples in Doxygen documentation?

There are a few ways you can organize multiple examples in Doxygen documentation:

1. Use the \verbatim and \endverbatim commands to display code examples as-is, without any additional formatting. This is useful for longer code examples or examples that require specific formatting.
2. Use the \code and \endcode commands to display code examples with syntax highlighting and line numbering. This can help make code examples easier to read and understand.
3. Use the \codeline command to include a single line of code within a paragraph of text. This can be useful for providing context or explaining a specific part of a code example.
4. Use the \par command to create a new paragraph within a code example. This can help break up longer code examples into more digestible chunks.

Overall, the key to organizing multiple examples in Doxygen documentation is to structure them in a logical and coherent way that makes it easy for readers to follow along and understand the code you are presenting. Remember to use descriptive comments and annotations to provide context and explanations for each code example.

What is the recommended way to document examples in Doxygen?

The recommended way to document examples in Doxygen is to use the \code command to enclose the code or example that you want to document. This will ensure that the code is displayed correctly in the generated documentation. Additionally, you can use the \code and \endcode commands to mark the beginning and end of the code block.

Here is an example of how to document an example using Doxygen:

/**
 * @brief This function adds two numbers.
 *
 * This function takes two numbers as input and returns the sum of the numbers.
 *
 * @param a The first number to add
 * @param b The second number to add
 *
 * @return The sum of the two numbers
 *
 * @code
 * int add(int a, int b) {
 *     return a + b;
 * }
 * @endcode
 */
 int add(int a, int b) {
     return a + b;
 }

In the above example, the code block is enclosed within the \code and \endcode tags, which ensures that the code is displayed correctly in the generated documentation.
