Creating Comprehensive Package Documentation with Godoc

When utilizing godoc to generate HTML documentation for Go packages, it is possible to recursively iterate through subdirectories and include all contained packages in the generated file.

The godoc Command

Running godoc with the -html flag generates static HTML documentation for a package. However, by default, this documentation only covers the current directory or a specific file provided as an argument.

Recursive Documentation Generation

To generate documentation recursively for all subdirectories within a package, modify the godoc command as follows:

godoc -html -goroot="mypath" pkg/ ... > index.html

The addition of ... to the command instructs godoc to recursively traverse all subdirectories of the specified pkg directory and generate documentation for any Go package it finds.

Package Separation

It's important to understand that Go doesn't have a concept of subpackages. All packages are distinct and should have their own documentation. Therefore, attempting to merge documentation from multiple subdirectories into a single file is not idiomatic.

Instead, each package should be documented separately, allowing users to easily access the relevant documentation for the specific package they are interested in. This avoids clutter and confusion, enabling users to quickly navigate and find the information they need.
