How to Add Extension to Doxygen?

To add an extension to Doxygen, you first need to make sure that the extension is compatible with Doxygen. You can typically find extensions in the form of plugins or custom means of generating documentation.

Once you have the extension that you want to add, you can typically include it in your Doxygen configuration file. This file is usually named "Doxyfile" and can be edited using a text editor.

Within the Doxyfile, you will need to look for the section that specifies the INPUT variable. This variable specifies the input files or directories to be processed. In this section, you can add the path to the extension that you want to include.

After making these changes, you can run Doxygen normally, and it should process the extension along with your regular documentation. Make sure to check the output of the Doxygen run to ensure that the extension has been successfully added and processed.

How to modify the behavior of doxygen for non-standard input files?

To modify the behavior of Doxygen for non-standard input files, you can use one or more of the following methods:

1. Define new file extensions: In your Doxygen configuration file, you can define custom file extensions for files that are not recognized by default. You can do this by using the FILE_PATTERNS directive to specify which file extensions should be considered as input files for Doxygen.
2. Use the INPUT directive: You can specify the paths to specific input files or directories that you want Doxygen to process by using the INPUT directive in your configuration file.
3. Create custom input filters: If you have input files that do not conform to the standard format expected by Doxygen, you can create custom input filters to preprocess these files before they are processed by Doxygen. You can specify these filters using the INPUT_FILTER directive in your configuration file.
4. Use custom parsers: Doxygen allows you to define custom parsers for processing input files with non-standard formats. You can create a custom parser and specify it using the EXTENSION_MAPPING directive in your configuration file.

By using these methods, you can customize the behavior of Doxygen to handle non-standard input files and ensure that they are processed correctly.

How to define a preprocess step for handling custom file formats in doxygen?

To define a preprocess step for handling custom file formats in Doxygen, you can follow these steps:

1. Write a script or program that will preprocess your custom file format into a format that Doxygen can understand. This script should take your custom file as input and output a file in a format that Doxygen recognizes, such as a .txt or .h file.
2. Set up your Doxygen configuration file (Doxyfile) to include the preprocess step. You can do this by adding a preprocessor definition specifying the command or script to run before parsing the custom file. For example:

1
2

ENABLE_PREPROCESSING=YES
PREPROCESSING=/path/to/your/preprocess_script.sh

1. Run Doxygen with your updated configuration file to preprocess your custom file and generate the documentation. Doxygen will run your preprocess script before parsing the custom file, allowing it to recognize and document the contents of the file correctly.

By following these steps, you can define a preprocess step for handling custom file formats in Doxygen and generate documentation for your custom files effectively.

How to parse custom file types in doxygen with special processing rules?

To parse custom file types in Doxygen with special processing rules, you can define a new input filter in the Doxygen configuration file.

Here is an example of how you can define a new input filter for a custom file type:

1. Open your Doxygen configuration file (typically named Doxyfile).
2. Add the following lines to define a new input filter for your custom file type (replace customfile with the actual file extension of your custom file type):

1
2

INPUT_FILTER = "sed 's/^[ \t]*//' | path/to/custom_parser_script.sh"
FILE_PATTERNS = "*.customfile"

1. Create a custom parser script (e.g., custom_parser_script.sh) that implements the special processing rules for your custom file type. This script should read the input from stdin and output the processed content to stdout.
2. Make sure the custom parser script is executable:

1

chmod +x custom_parser_script.sh

1. Run Doxygen as usual to generate the documentation. Doxygen will use the input filter and custom parser script to parse and process your custom file type according to the specified rules.

By defining a custom input filter and parser script in Doxygen, you can apply special processing rules to your custom file types and include them in the generated documentation.

How to specify a fallback for unrecognized file types in doxygen?

To specify a fallback for unrecognized file types in Doxygen, you can use the FILE_PATTERNS configuration option in your Doxygen configuration file.

Here's how you can do it:

1. Open your Doxygen configuration file (typically named Doxyfile).
2. Locate the FILE_PATTERNS option in the configuration file.
3. Add an entry for the unrecognized file type with a corresponding fallback file type. For example, if you want to specify a fallback for a file type .xyz, you can add the following entry:

1

FILE_PATTERNS = *.xyz=*.txt

1. Save the configuration file and regenerate your Doxygen documentation.

With the above configuration, Doxygen will use the specified fallback file type (in this case, .txt) for any files with the unrecognized file type (in this case, .xyz). You can customize the fallback file type as needed to suit your project requirements.

How to customize the behavior of doxygen for specific file extensions?

To customize the behavior of Doxygen for specific file extensions, you can use the EXTENSION_MAPPING option in the Doxygen configuration file.

Here's how you can customize the behavior for specific file extensions:

1. Open the Doxygen configuration file (usually named Doxyfile).
2. Search for the EXTENSION_MAPPING option in the configuration file.
3. Add or modify the entry for the specific file extension you want to customize. The syntax for EXTENSION_MAPPING is as follows:

1

EXTENSION_MAPPING = <file extension>=<language id>

For example, if you want to customize the behavior for files with the .cpp extension and treat them as C++ files, you can add the following entry:

1

EXTENSION_MAPPING = cpp=C++

1. Save the changes to the configuration file and regenerate the Doxygen documentation.

By customizing the behavior of Doxygen for specific file extensions using the EXTENSION_MAPPING option, you can ensure that the documentation generation process is tailored to the specific needs of your project.

How to specify multiple file extensions for a single output type in doxygen?

In Doxygen, you can specify multiple file extensions for a single output type by using the FILE_PATTERNS configuration option in the Doxygen configuration file (Doxyfile).

To specify multiple file extensions for a single output type, you can do the following:

1. Open the Doxyfile in a text editor.
2. Locate the FILE_PATTERNS configuration option in the Doxyfile. If it does not exist, you can add it.
3. Add the file extensions that you want to include for the output type separated by spaces. For example, if you want to include .h and .hpp files for the output type, you can add the following line:

1

FILE_PATTERNS = *.h *.hpp

1. Save the Doxyfile and run Doxygen to generate the documentation with the specified file extensions included for the output type.

By specifying multiple file extensions using the FILE_PATTERNS configuration option, you can customize the types of files that are included in the documentation output.
