Description
What did you do?
I installed vim-go on Windows 10, using the vim packages install method.
Saving a .go file triggers autoformatting, and that always failed with errors like this:
C:/Users/Joao/go-web-playground/hello/hello.go:JSON RPC parse error: DocumentURI scheme is not 'file': C%3A%2FUsers%2FJoao%2Fgo-web-playground%2Fhello%2Fhello.go
I believe this happens because the code in go#path#ToURI has special logic for Windows that is looking for backslashes, but my vim is using forward slashes on Windows instead.
This turns out to be caused by set shellslash on my .vimrc. Removing that fixes this problem.
However, I really prefer to use forward slashes by default, as I work mostly on WSL (Windows Subsystem for Linux).
I don't know enough vim script to upload a fix, but maybe go#path#ToURI could handle both backward and forward slashes on Windows? :-)
(FWIW, the OS supports both)
