How Can I Document the `main` Package in Godoc?

Documenting package main in Godoc

Godoc, a powerful package documentation tool, presents challenges when used with the main package. Unlike exported functions, functions within package main remain hidden from Godoc's output.

To address this issue, consider the following steps:

Customizing Godoc

• Modify $GOPATH/src/golang.org/x/tools/godoc/server.go and change the following line:

- info.IsMain = pkgname == "main"
+ info.IsMain = false && pkgname == "main"

• Build and install the modified Godoc with go install golang.org/x/tools/cmd/godoc.

Benefits of Customizing Godoc

This customization allows Godoc to display functions within package main. It eliminates the need for manual updates and provides a comprehensive view of all package functions.

Alternative Solutions

If customizing Godoc is not feasible, consider these alternatives:

• Place as much code as possible in exported packages to increase the visibility of functions.
• Create additional source files containing exported functions that wrap the unexported functions in package main. This enables Godoc to document the wrapped functions.

By implementing these steps, you can effectively document your package main functions and benefit from the extensive documentation capabilities of Godoc. The customized Godoc version ensures that all functions, including those within package main, are visible and accessible for improved code understanding and documentation accuracy.
