GoDoc Playground (visit)

The GoDoc Playground lets you make changes to your packages documentation and see, in (near) realtime, exactly how this will be rendered on godoc.org.

Features

• Automagically fixes unresolved symbols so you don't need to paste in all your code, just a small snippet.
• Uses the actual godoc library to parse and render documentation so you can be confident your documentation will be rendered exactly as previewed.
• Completely in-browser: uses a GopherJS compiled parser/renderer so your code never leaves the browser. Even works offline!
