Scalariform on a Play project
In the last days I have been playing with some powerful tools for start web applications in a fast and easy way that resides on the Cloud. These tools are:
- Playframework As my web framework. It is really easy to start a web application on Play and is oriented to REST. Play supports Scala or Java as a language (I recommend to use Scala).
- Heroku It is really simple to deploy a Scala application. I tried Openshift but is more complicated since they don’t have an environment for Scala (You need to use a DIY).
- MongoDB Really easy and powerful NoSQL database.
You can check the app here.
Finally after some attempts I was able to run my sample application. I was using Atom as my code editor (I needed to add a plugin to recognize the Scala syntax). I can say that Atom is a really good tool to edit Scala files but it doesn’t have plugins to format code like Eclipse or Intellij IDEA. Fortunately exists a tool in Scala (Scalariform) to format the code. You can run as an external tool or include in your SBT (Also is the plugin that Eclipse uses to format the code).
I chose to run Scalariform from my SBT script. The default behavior is that Scalariform is executed when the code is compiled but you can change the default behavior. I use the default behavior.
The only thing you need to do is add the Scalariform plugin into the plugins.sbt file. The file is located in:

To use the plugin just add this line in plugins.sbt

And that’s all!.
Now on every project compilation Scalariform will format all the Scala code :D. You can modify the default settings of Scalariform if you want a different style. The recommendation is to use the Scala Style Guide
