How Can I Use Godoc to Document Unexported Functions in a `main` Package?

Godoc Documentation for Package Main

Godoc efficiently facilitates package documentation, but encounters challenges when applied to package main, displaying only exported functions and omitting unexported functionalities.

Steps to Document Package Main

To address this, a modified version of godoc is required:

1. Modify godoc Server File:

   • Navigate to $GOPATH/src/golang.org/x/tools/godoc/server.go
   • Locate the line containing "info.IsMain = pkgname == "main"" and change it to "info.IsMain = false && pkgname == "main"".

2. Build and Install Godoc:

   • Run "go install golang.org/x/tools/cmd/godoc"

Benefits of Modifying Godoc

Upon completing the modification, $GOPATH/bin/godoc will accurately display:

• Exported and unexported functions
• Function signatures
• Location within main.go file

This enhanced documentation aids developers in comprehensively understanding the package main's functionality.

Package Organization

Regarding the list of functions in main, it is generally not advisable to place excess code in packages solely for documentation purposes. Maintaining a concise package structure fosters code readability and reduces unnecessary duplication.
