Delve: a debugger for Go, written in Go
This highlights my biggest criticism with Go (although I am a fan generally), the lack of a great IDE with powerful refactoring, debugging, test runner integration etc. These tools can be a great advantage of having a strongly typed static language. The current options are below par, hopefully jetbrains will step up and fill the void.General response to comments:
I think some people may not have seen what you can do with a good IDE and a strongly typed static language. Want to rename a function throughout the entire app and guarantee it works, no problem. How about moving a file and having all the imports changed to the new location, easy. You can't do that in ruby, but in Go/Java/C# it should be trivial with good tooling. If that does exist I would love to see it.
