A Source Code Documentation is a collection of documentation within the source code of a software program that explains how the code works or should be used.

  • Context:
    • It can (typically) include Code Comments, which are annotations within the code that explain the logic, functionality, or purpose of various code segments to human readers.
    • It can (often) consist of Docstrings in languages like Python, which provide a convenient way of associating documentation with Functions, Classes, Modules, or entire scripts.
    • It can be used to generate external documentation automatically through tools like Javadoc for Java, Doxygen for languages such as C++, C, and Sphinx for Python.
    • It can improve Code Readability and Software Maintainability by making the codebase easier for other developers to understand.
    • It can include inline documentation that explains the purpose of variables, the reasoning behind algorithm choices, and steps of complex logic.
    • It can serve as a reference for developers when updating or debugging existing code, reducing the effort required to familiarize oneself with unfamiliar codebases.
    • It can vary in detail and scope, from brief comments explaining a single line of code to comprehensive guides embedded within the code that explain entire modules or systems.
    • It can facilitate Software Testing and Quality Assurance processes by providing insights into intended functionality and behavior.
    • It can sometimes be neglected or given lower priority in fast-paced development environments, leading to software maintenance and enhancement challenges.
