gin

gin is a simple command line utility for live-reloading Go web applications. Just run 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 HTTP request.

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.

Installation

Assuming you have a working Go environment and GOPATH/bin is in your PATH, gin is a breeze to install:

go get github.com/codegangsta/gin

Then verify that gin was installed correctly:

gin -h

Supporting Gin in Your Web app

gin assumes that your web app binds itself to the PORT environment variable so it can properly proxy requests to your app. Web frameworks like Martini do this out of the box.
