Hi @saibing! I'm one of the people currently working on golang.org/x/tools/cmd/golsp. We recently noticed and were excited to see your work on bingo. Our plan for golsp is for it to become the official language server supported by the Go team, and the folks at Sourcegraph have agreed that they would eventually like to use our code once it is ready.

We noticed that a lot of the code in this repository is shared with golsp and with go-langserver, so we were wondering if you would be interested in collaborating with us on golsp. More information about golsp can be found through the various channels listed here. If you'd like to continue this conversation, I'm happy to talk on this issue or via email (rstambler@golang.org).
