Quinn from Sourcegraph here. Thanks for posting this! It was actually a quick hack project I built on our API for fun last night. It basically uses sourceboxes (https://sourcegraph.com/blog/sourceboxes-a-better-way-to-embed-code-snippets https://sourcegraph.com/blog/sourceboxes-a-better-way-to-emb...), which are like Gists but with jump-to-def and doc tooltips, to display the function and type signatures for godoc definitions. It's pretty rough, but we'd love to hear feedback. And if anyone else wants to build similar tools using sourceboxes or our API, go for it and reach out if I can be helpful (sqs@sourcegraph.com). BTW, thanks to the awesome @kisielk (gorilla maintainer, etc.) for the gosrc.org domain. You can just go to gosrc.org/github.com/some/pkg to use gosrc.org for any package.
