With the vim-go plugin, Vim gets all
kinds of support for working with a Go project. Generally, with a Go
project, you have to run go build to compile the project and if that is
successful, you can run go install to put the executable binary on the
$GOPATH.
This plugin allows you to tighten the feedback loop. You can build right within your Vim session using
:GoBuild
which will alert you to any compilation errors.
You can then install the program using
:GoInstall
Your program is now ready to run.
It's worth noting that this plugin will also notify you about syntax errors when you save, if they exist.
