Scala> :load /Users/Al/ProjectX/Person.scala Note, however, that if your source code has a package declaration: Scala> val al = Person('Alvin Alexander')

Once the code is loaded into the REPL, you can create a new Person instance: Loading /Users/Al/ScalaTests/Person.scala. You can load that source code into the REPL environment like this: For example, assume you have the following source code in a file named Person.scala in the same directory where you started the REPL: Similarly, if you have source code in a file that you want to read into the REPL environment, you can use the :load command.

Press Ctrl-D, and the REPL will evaluate what you pasted in.

Paste in your block of code (Command-V on a Mac, Ctrl-V on Windows).

Entering paste mode (ctrl-D to finish)Īs shown, follow these steps to paste your code into the REPL: The :paste commandĪttempting to paste the following if/else block into the REPL will cause an error:īut by issuing the :paste command before pasting in the code, the code will be interpreted properly:

To solve the problem, either use the :paste command to paste blocks of code into the REPL, or use the :load command to load the code from a file into the REPL. The REPL is “greedy” and consumes the first full statement you type in, so attempting to paste blocks of code into it can fail. You want to experiment with some code in the Scala REPL, and typing it in or trying to paste it into the REPL won’t work. This is Recipe 14.2, “How to paste and load blocks of code in the Scala REPL.” Problem This is an excerpt from the Scala Cookbook. show more info on classes/objects in repl.
