doxygen

Doxygen is a popular command line tool used for generating documentation from annotated source code. It is particularly useful for projects written in C++, C, Python, Java, and other languages.

With Doxygen, developers can describe the structure and purpose of their code using specific tags and comments within the source code files. These tags include information about classes, functions, variables, and other elements. The tool then parses these source files and generates a wide range of documentation formats, including HTML, PDF, LaTeX, RTF, and more.

Doxygen allows for the generation of various types of documentation, including API reference documentation, class hierarchy diagrams, collaboration diagrams, and even cross-referencing between different parts of the codebase. It can also extract class and method documentation from header files or inline comments and merge them into the generated documentation.

Furthermore, Doxygen supports documentation customization through its configuration file. Developers can modify the generated output by specifying options such as layout, styling, and page ordering. Additionally, it provides support for including external documentation, linking to external resources, and adding diagrams, charts, or images to the generated documentation.

Overall, Doxygen simplifies the process of documenting code by automatically generating comprehensive and readable documentation, making it easier for developers, users, and other stakeholders to understand and use the codebase.
