How Can I Effectively Document Unexported Functions in My Go `package main` with Godoc?

Documenting package main in Godoc: A Comprehensive Guide

Despite its usefulness for package documentation, Godoc poses limitations when applied to package main. This article delves into the necessary steps to document package main effectively in Godoc, addressing concerns about unexported functions and creating a comprehensive documentation experience.

One challenge lies in Godoc's focus on exported functions, rendering unexported functions in package main invisible. This has prompted users to resort to a workaround of manually listing functions at the top of the package description. While this approach provides temporary visibility, it raises questions about its long-term practicality.

The alternative solution involves modifying the Godoc codebase. By adjusting the code in $GOPATH/src/golang.org/x/tools/godoc/server.go, specifically the line info.IsMain = pkgname == "main", you can ensure that package main is treated differently.

Once the modification is complete, build and install the updated Godoc with go install golang.org/x/tools/cmd/godoc. This action will enable $GOPATH/bin/godoc to display unexported functions in package main.

This modification addresses the issue of documenting unexported functions, providing a more comprehensive documentation experience for package main. However, it does require manual intervention and code modification. It is crucial to carefully consider the trade-offs before implementing this solution.
