Summary: Command Line Interface for Language Level Converter

Initial Comment:
There is a command line version of the language level converter that can be invoked using

java -cp drjava.jar edu.rice.cs.javalanglevels.LanguageLevelConverter MyFile.dj1 MyOtherFile.dj1

but it seems to have trouble with the classpath. It should be made very easy to use the command line interface. Perhaps the best thing would be to integrate the interface into DrJava so it can be invoked using

java -jar drjava.jar -jll MyFile.dj1 MyOtherFile.dj1

----

Here is an example of the current class path problem:

import junit.framework.*;

public class TestGCDLL extends TestCase {
    public int gcd(int x, int y) {
        if(y == 0) {
            return x;
        }
        else {
            return gcd(y, x%y);
        }
    }
    
    public void testGCD() {
        assertEquals(3, gcd(6,9));
    }
}

% java -cp /Applications/Dev/drjava.jar edu.rice.cs.javalanglevels.LanguageLevelConverter TestGCDLL.dj1
1 errors.
Converter could not resolve TestCase [TestGCDLL.dj1: (3,32)-(3,39)]

Even though junit.framework.TestCase is included in drjava.jar.
