If you haven't installed Activator, you can get the code by downloading the template bundle for atomic-scala-examples.

  1. Download the Template Bundle for "Atomic Scala Examples"
  2. Extract the downloaded zip file to your system
  3. The bundle includes a small bootstrap script that can start Activator. To start Typesafe Activator's UI:

    In your File Explorer, navigate into the directory that the template was extracted to, right-click on the file named "activator.bat", then select "Open", and if prompted with a warning, click to continue:

    Or from a command line:

     C:\Users\typesafe\atomic-scala-examples> activator ui 
    This will start Typesafe Activator and open this template in your browser.

Option 3: Create a atomic-scala-examples project from the command line

If you have Typesafe Activator, use its command line mode to create a new project from this template. Type activator new PROJECTNAME atomic-scala-examples on the command line.

Option 4: View the template source

The creator of this template maintains it at https://github.com/AtomicScala/atomic-scala-examples.

Option 5: Preview the tutorial below

We've included the text of this template's tutorial below, but it may work better if you view it inside Activator on your computer. Activator tutorials are often designed to be interactive.

Atomic Scala

Atomic Scala introduces the foundations of the Scala programming language in very small steps (which we call atoms). The book is designed to simplify learning the language for both beginners and experienced programmers. To get started download the first hundred pages of the book.

Run the Examples

All of the examples from the book can be found in the examples directory. Select a file to edit it. Run an example from the Activator UI by editing ExampleRunner.scala and putting the file name into the getOrElse part, like:

Then in Run select ExampleRunner from the drop-down menu and click the Start button. Whenever the code changes, the file specified in ExampleRunner.scala will automatically be re-run. If you want to run a different file simply change the file name there and click the Save button.

The examples can also be run from the command line by running the following from the main project directory (omit the ./ on Windows):
./activator "run-main ExampleRunner"
You can also specify the example to run from the command like, like:
./activator "run-main ExampleRunner DivZero.scala"
