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.

• my main go file is under src/main/main.go. Normally I use go build -o bin/main main which is not workable under the origianl gin.

• Monitor all files under src folder.

• Monitor not only .go file, but also .tmpl file.

Thus I modified the command input a bit, in order to be able to pass the folder name for building and the src for watching any changes.

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

go get github.com/stefanzan/gin

Then verify that gin was installed correctly:

gin -h

How to use it ? (2015/09/05)

You can modify the run.sh to feed your own needs. Basically,

gin -a "8000" -p "3000" -m "main"

main is a folder under src folder, in which there is a main file named main.go .

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.

When you normally start your server with flags if you want to override any of them when running gin we suggest you instead use github.com/namsral/flag as explained in this post
