godoc

Godoc is a command-line tool that is part of the Go Programming Language. It is used to generate documentation for Go packages, including both the standard library and user-defined packages. The tool extracts information about the package's API from the source code comments in Go files and presents it in a web-based format.

Godoc allows developers to quickly browse and search documentation for any installed package on their local machine. It provides easy navigation through package directories, listings of exported symbols (functions, types, variables), and shows associated documentation comments. Users can also generate static HTML pages for viewing offline.

Additionally, Godoc serves as a development tool that can display the documentation inline with Go code during coding and while exploring unfamiliar codebases. This integration simplifies the process of understanding and using external packages and promotes the documentation-driven development process.

Godoc is an essential tool for Go developers as it makes it easy to access and understand package documentation, promoting the Go community's emphasis on clear, self-contained code with comprehensive documentation.
