Reading Go documentation with gddo

2022-07-16 on

Today, I am pleased to announce the release of version 1.6 of gddo, the software powering For those unaware, gddo is a maintained fork of the software which powered the now-defunct It runs as a web server and serves documentation for Go packages.

This release focuses on improving the local documentation viewing experience. gddo now supports serving documentation for modules in the current directory, allowing you to preview documentation while making changes locally. This makes gddo a good replacement for the now-deprecated godoc tool, and a lightweight alternative to the pkgsite command.

To view documentation locally, simply run:

cd my-module
gddo --http :8080

Then navigate your web browser to http://localhost:8080 to view the documentation for your module.

gddo will also serve documentation for your local copy of the standard library, as well as any modules you have downloaded in your Go module cache, allowing you to easily view the documentation for your dependencies.

gddo is still not a complete replacement for the godoc tool. If you are missing a feature from godoc and want to implement it for gddo, patches are welcome!
