gin is a simple command line utility for live-reloading Go web applications.
gin in your app directory and your web app will be served with
gin as a proxy.
gin will automatically recompile your code when it
detects a change. Your app will be restarted the next time it receives an
gin adheres to the "silence is golden" principle, so it will only complain
if there was a compiler error or if you succesfully compile after an error.
Assuming you have a working Go environment and
GOPATH/bin is in your
gin is a breeze to install:
go get github.com/codegangsta/gin
Then verify that
gin was installed correctly:
gin run main.go

Supporting Gin in Your Web app
gin assumes that your web app binds itself to the
variable so it can properly proxy requests to your app. Web frameworks
