How to use the JRuby Complete framework in the Java library

How to use the JRuby Complete framework in the Java library JRuby is a Ruby interpreter running on the Java virtual machine (JVM) that allows developers to use Ruby code in Java applications.JRuby Complete is a JRUBY distribution version that provides a complete Ruby language function.In this article, we will explore how to use the JRuby Complete framework in the Java class library. Step 1: Install JRuby Complete First, you need to download and install the JRuby Complete framework from the official website of JRuby (https://www.jruby.org/).The installation process is similar to any other Java library. Step 2: Configure items Next, you need to configure the JRuby Complete framework to your Java project.The JAR file containing the JRuby Complete framework in the project's ClassPath.You can also add it to the dependency item configuration of the project construction tool (such as Maven or Gradle). Step 3: Use JRuby Complete framework Once your project configuration is completed, you can start using the JRuby Complete framework in the Java class library.The following is a simple example: import org.jruby.embed.LocalContextScope; import org.jruby.embed.LocalVariableBehavior; import org.jruby.embed.ScriptingContainer; import org.jruby.embed.internal.LocalContextProvider; public class JRubyExample { public static void main(String[] args) { ScriptingContainer container = new ScriptingContainer(LocalContextScope.THREADSAFE, LocalVariableBehavior.PERSISTENT); container.put("name", "John"); String script = "puts 'Hello ' + name"; container.runScriptlet(script); } } In the above example, we first introduced the necessary class of the JRuby Complete framework.Then, we created a ScriptingContainer object that is used to run the Ruby code.We pass a variable called "John" to the Ruby script and use the RunScriptlet method to run the script. Step 4: Run code Compile and run the above Java class.You will see the console output "Hello John". The above is the basic step of using the JRuby Complete framework in the Java library.Please note that if you have other dependent items or configuration requirements, you may need to adjust the project settings according to the relevant documentation. I hope this article can help you start using the JRuby Complete framework in the Java class library.I wish you a pleasant code!
