Note
I am very sorry that I have planned not continue to maintain this project.
According to the issue #13 collaborating on golsp, I hope that we will eventually have a unified language server:
gopls.
It is Google's upcoming Go language server. It is in the best interests of the community to only have a single language server.
I have ported some features such as references, rename, workspace symbol, implementation of bingo to gopls.
If you want to use the enhanced version of gopls, try https://github.com/saibing/tools.
