How to Use Exclude_symbols Correctly In Doxygen?

In Doxygen, the exclude_symbols configuration option can be used to exclude specific symbols from being documented in the generated output. This can be useful when there are certain functions, classes, or variables that are internal to the code base and not intended to be part of the public API documentation.

To use exclude_symbols correctly in Doxygen, you need to specify the names of the symbols that you want to exclude in the Doxyfile configuration file. This can be done by adding a line like this:

exclude_symbols = privateFunction, InternalClass, m_internalVariable

In this example, the symbols privateFunction, InternalClass, and m_internalVariable will be excluded from the documentation. You can specify multiple symbols by separating them with commas.

It's important to note that the names of the symbols should match exactly what is defined in the code. It's also possible to use wildcard characters to exclude multiple symbols that follow a certain pattern. For example, you could use a wildcard like *_internal to exclude all symbols that end with "_internal".

By using the exclude_symbols option in Doxygen, you can control which symbols are included in the generated documentation, helping to keep the documentation focused on the public API and improving its readability and usability.

What are some examples of when to use exclude_symbols in doxygen?

1. When documenting code that contains special symbols or characters that may be misinterpreted by Doxygen.
2. When generating documentation for code that involves mathematical expressions or formulas.
3. When documenting code that includes non-standard symbols or ASCII characters that may not be supported by Doxygen.
4. When documenting code that uses custom symbols or characters that are specific to a particular programming language or framework.
5. When documenting code that includes symbols or characters that may conflict with Doxygen's syntax or formatting rules.

What is the best way to test the exclude_symbols functionality in doxygen?

The best way to test the exclude_symbols functionality in Doxygen is to create a small test project with various symbols (e.g. classes, functions, variables) and then use the exclude_symbols configuration option in the Doxyfile to exclude specific symbols from the generated documentation.

Here are the steps to test the exclude_symbols functionality in Doxygen:

1. Create a small test project with multiple symbols in different source files (e.g. classes, functions, variables).
2. Configure the Doxyfile to include the source files and enable the EXTRACT_ALL option to extract all symbols from the source code.
3. Use the exclude_symbols configuration option in the Doxyfile to exclude specific symbols from the generated documentation. You can exclude symbols based on their names or patterns using regular expressions.
4. Run Doxygen to generate the documentation and verify that the excluded symbols are not included in the output.
5. Make any necessary adjustments to the configuration and repeat the process until you are satisfied with the results.

By following these steps, you can effectively test and validate the exclude_symbols functionality in Doxygen to ensure that it works as expected for your project.

How do I exclude global variables from my doxygen documentation using exclude_symbols?

To exclude global variables from your Doxygen documentation using exclude_symbols, you can add a configuration option in your Doxyfile as follows:

1

EXCLUDE_SYMBOLS = global_variable_name1 global_variable_name2 ...

Replace global_variable_name1, global_variable_name2, etc. with the names of the global variables you want to exclude from the documentation.

For example:

1

EXCLUDE_SYMBOLS = g_myGlobalVariable1 g_myGlobalVariable2

Make sure to run Doxygen again after updating the configuration file for the changes to take effect.

How do I handle conflicts between excluded symbols in doxygen?

Conflicts between excluded symbols in Doxygen can be handled by ensuring that the documentation for each symbol is clearly defined and differentiated.

One approach is to add specific comments or tags to each symbol that is excluded, explaining the reason for exclusion and any alternative documentation or references that may be relevant. This can help to prevent confusion and make it easier to understand why certain symbols were excluded.

Additionally, you can use the "exclude" tag in Doxygen to explicitly exclude certain symbols from being documented. This tag can be applied to individual symbols or entire sections of code, helping to clean up the documentation and streamline the documentation process.

Overall, the key is to be clear, consistent, and thorough in how you handle conflicts between excluded symbols in Doxygen. By following these guidelines, you can effectively manage conflicts and ensure that your documentation remains accurate and easy to navigate.

What is the most efficient way to use exclude_symbols in doxygen?

The most efficient way to use exclude_symbols in Doxygen is to specify the symbols that you want to exclude in the Doxyfile configuration file. This way, you can define the specific symbols that you want to exclude from the documentation generation process without having to manually exclude them within the code.

Here is an example of how to use exclude_symbols in the Doxyfile:

1
2

# Exclude symbols from the documentation
EXCLUDE_SYMBOLS = PrivateClass::PrivateMethod, DEBUG_MODE

In this example, the symbols PrivateClass::PrivateMethod and DEBUG_MODE will be excluded from the documentation. This can help to improve the clarity and focus of the generated documentation by removing internal implementation details or debug-specific code.
