JythonScript 2.0.x

Description:

JythonScript is a simple Jython wrapper for easier execution and/or evaluation of Python expressions and scripts at runtime for JVM-based languages.

Maven

<dependency>
  <groupId>com.github.adchilds</groupId>
  <artifactId>jythonscript</artifactId>
  <version>2.0.1</version>
</dependency>

Dependencies:

None. JythonScript packages the Jython standalone JAR as part of it's distribution, so no further dependencies are required.

Examples:

test.py:

from java.lang import System

def test():
	System.out.println('Hello from Jython')

if __name__ == '__main__':
	test()

Test.java:

import com.github.adchilds.jython.JythonScript;

public class Test {

	public static void main(String[] args) {
		String filePath = ClassLoader.getSystemResource("test.py").getPath();
		
		JythonScript.execute(filePath);
	}
}

Output: "Hello from Jython"

test2.py:

import sys

def multiply(a, b):
	return a * b

if __name__ == '__main__':
	a = sys.argv[1]
	b = sys.argv[2]

	result = multiply(a, b)

Test2.java

import com.github.adchilds.jython.JythonScript;

public class Test2 {

	public static void main(String[] args) {
		String filePath = ClassLoader.getSystemResource("test2.py").getPath();
		
		Integer result = JythonScript.evaluate(filePath, 5, 5);
		System.out.println("Result = [" + result + "]");
	}
}

Output: "Result = [25]"

Test3.java

import com.github.adchilds.jython.JythonScript;
	
public class Test2 {
	
	public static void main(String[] args) {
		String script = "from java.lang import System\n" +
                        "\t\n" +
                        "\tdef test():\n" +
                        "\t\tSystem.out.println('Hello from Jython')\n" +
                        "\t\n" +
                        "\tif __name__ == '__main__':\n" +
                        "\t\ttest()";
		
		PyCode compiledScript = JythonScript.compileString(script);
		JythonScript.execute(compiledScript);
	}
}

Output: "Hello from Jython"
