Scala IDE

Definition of Scala IDE

Scala is an object-oriented programming language that has so many similarities like java. If we talk about IDE it is the tool by which we can write our code and they provide us much support for the language. When we work with any programming language we should choose our editor very wisely. With the use of IDE, we can also check-in and checkout our code to remote they come with various features. For scala also we have many different IDE available where we can edit our code and make it work the way we want.

List of Scala IDE with Explanation

We have a list of different IDE’s available in the market to edit our code. If we talk about Java the most popular editor we have is eclipse and intellij. Below we can see the list of editors that we can use for scala language which are as follows;

1. Intellij IDEA

Intellij idea is one of the most popular IDE we have. This editor provides supports or many languages which cover most of them like; java, typescript, groovy, scala, SQL, Kotline, javascript, and many more. Inside this, we have so many build tools available that can be used to create our project based on the requirement. In this, we have ANT, maven, and gradel support to make our applications. With the use of this, we can create a new project, import the existing project into the workspace which makes the development easy. To start with intellij idea and how to use scala with it we will see some steps to follow which are mentioned below;

• In order to start first, we need to download intellij idea into our system. We can download IntelliJ Community Edition for better support for the language.
• In the second step, we have to check whether java is installed in our machine or not. If not then we have to install it because scala uses java libraries. To check java installed or not we have one command for this, we should check for its version javac -version. You should have java 8 installed in your machine if not then we should install the Java Jdk 8 or higher.
• After setting up java, we can open the Intellij idea and set the version of java we want to use for the specific project.
• Now open intellij and download the plugin for Scala form market place. Go to file >> settings >> then search for scala plugin and type scala into it. You will see various plugin for scala. Download the most appropriate one.
• Now we will create a new project for scala, for this click on File > New > Project. This will open a panel where we have to select for the scala at the left-hand side.
• Give the name of the project. Example: DemoScalaProject
• We are creating the scala project for the first time so we need to setup the scala SDK as well. On the right hand side click on SDK and click Create.
• After setting all things click on finish.
• Now start writing code for scala. Go to the src folder and start writing your code. we can have one sample program to show its working see below;

object Main extends App{
// Your code here!
println("Welcome to Scala.!!")
println("Setup done.")
}

2. Eclipse for Scala

Eclipse also provides support for various programming languages. Which includes java, groovy, scala, typescript, and many more? It also has strong support for version control as well like; git, perforce, svn, etc. We can easily create our application using eclipse because in the market place it has so many plugins and support available for this. It provides various build in a tool such as a maven, ant,gradel, etc. We can also create web based applications very easily by using it. To start with scala we have to follow some steps below;

• To start with setting up a scala with Eclipse we have to download the eclipse installer for this. With the use of an eclipse installer, we can download the latest version for eclipse easily.
• After setting up eclipse we have to check for our java version. If java is not available in your machine, then download the latest one. JDK 8 or higher.
• Also, we have to download the Scala plugin from the eclipse marketplace for this inside eclipse search for the marketplace and type Scala there. You will see various available plugin for Scala. Download one from the list.
• After downloading plugin we will create one project. So click on File > New > Scala Project. You will see this option only when you have successfully installed a scala plugin into your eclipse.
• Before creating of the project setting up the SDK for scala also inside the settings menu.
• You will see a new window after clicking on the scala project. Provide a suitable name for your project and click finish.
• After finishing it will take around 3-4 seconds to load the project into the project explorer. Then you will see a project got created into your workspace by the name you have given.
• Go to the src folder, here you can create your own packages and classes to start with your code.

Code:

object Main extends App{
// Your code here!
println("Welcome to scala.!!")
println("Setup done using eclipse.")
}

From eclipse, you can check out your code as well. We just have to select the correct version control for this.

3. NetBeans for Scala

This is also one of the popular editors which provide support for various languages. But I would suggest you to go for an eclipse or intellij idea because they are more user friendly with lots of support available with less configuration. Let’s get started with net beans. Follow the below steps to work setting up the environment;

• First, we need to download the Netbeans for our machine. You can go for this >> NetBeans 6.7.1 – NetBeans 6.7.1 latest nightly.
• After setting up this we have to download the scala and setting up into home variable.
• After downloading of the scala file unzip it and open the environment variables >> go to your properties >> click on advance system properties.

• Add the path of scala here with the name of Scala_home
• We have to add this path for system variable.
• After setting up the scala home variable we have to download the scala plugin for Netbeans.
• Open net beans, go to the menu > tools > Plugin and look for an available plugin.
• At the top we have an option for the search for plugin >> search scala there and in some time you will see a list of the available plugin for scala.
• Select all the files and click install.
• We can create a new project by click on file > new project >scala project
• A new window will be appearing to type the name of the project and click finish.
