Creating HTML Documentation for an Entire Package Using Godoc

To generate HTML documentation for multiple packages simultaneously, including those in subdirectories, there is no direct method within the godoc tool. The concept of "sub packages" is not a inherent to Go, as all packages exist independently with distinct package declarations.

Therefore, it is not advisable to consolidate documentation from nested subdirectories into a single file. Instead, each package should have its own dedicated HTML documentation generated separately. This is because each package contains different functionalities and APIs, which warrants separate documentation to maintain clarity and organization.
