NaturalDocs

Natural Docs is a free and open-source documentation generator that supports 25 programming languages, with the ability to be extended for additional languages. It is designed for developers who need to produce readable source code documentation from comments, including projects that use multiple languages, as all languages can be included in the same set of documentation. The tool emphasizes natural language comments that are readable both in source code and in the generated output, avoiding unusual syntax or tags. Its generated documentation features three independently scrolling panels, dynamic menus, search functionality, and pop-up summaries when hovering over links. These features function regardless of whether the documentation is hosted on a web server, a network share, or opened locally from a hard drive. The software is available for download, and its website provides a getting started guide, a full reference, and a tour of what is new in version 2.0. Recent development updates include the addition of repository links to web-based sites like GitHub, which allow users to hover over a prototype to see a tab with a link to its source code, including support for files that define the same element across multiple files, such as header and source files in C++.
