jReddit

What is jReddit?

jReddit is a wrapper for the Reddit API written in Java. Project started by Omer Elnour. Taken over for further development and maintainence by Karan Goel.

What can it do?

jReddit can login with a user, retrieve user information, submit new links, and vote/comment on submissions, send and receive messages and notifications among other things.

What's next for jReddit?

The plan is to implement every feature documented here. To see which methods have been implemented, and which have not, see this file.

How to contribute?

Personally, I would suggest reading through the source code to understand the general structure and standards used. Then check the implemented_methods.md file to see which methods have not yet been implemented. Choose the ones you'd like to contribute to. After you write the method (and maybe commit it?), write a test to see if it works fine and as expected. Then make sure other tests are working too and your code does not break anty other method.

Send in a pull request with the test and I'll be happy to merge! :-)

Examples

Upvote every submission on the frontpage of a subreddit

import com.github.jreddit.submissions.Submission;
import com.github.jreddit.submissions.Submissions;
import com.github.jreddit.user.User;

public final class Test {
    public static void main(String[] args) throws Exception {
	    User user = new User("username", "password");
	    user.connect();

	    for (Submission submission : Submissions.getSubmissions("programming",
			    Submissions.Popularity.HOT, Submissions.Page.FRONTPAGE, user)) {
		    submission.upVote();
	    }
    }
}

Submit a link and self post

import com.github.jreddit.user.User;

public final class Test {
	public static void main(String[] args) throws Exception {
		User user = new User("username", "password");
		user.connect();

		user.submitLink(
				"Oracle V Google judge is a programmer!",
				"http://www.i-programmer.info/news/193-android/4224-oracle-v-google-judge-is-a-programmer.html",
				"programming");
		user.submitSelfPost("What's the difference between a duck?",
				"One of its legs are both the same!", "funny");
	}
}

List all submissions made by user called USERNAME_OF_OTHER_USER

import com.github.jreddit.submissions.Submission;
import com.github.jreddit.user.User;

/**
 * @author Benjamin Jakobus
 */
public final class Test {
	public static void main(String[] args) throws Exception {
		User user = new User("username", "password");
    		user.connect();

    		List<Submission> submissions = User.submissions("USERNAME_OF_OTHER_USER");
    		// To list hidden submissions, user User.hidden("...");
	
		for (Submission s : submissions) {
			// Print info here
		}
	}
}

Send a message to another user

import com.github.jreddit.message.Messages;
import com.github.jreddit.user.User;


public class ComposeTest {

	/**
	 * @author Karan Goel
	 */
	public static void main(String[] args) {
		User user = null;
		username_of_recipient = "other_user";
		try {
			user = new User("username", "password"); // Add your username and password
			user.connect();
		} catch (Exception exception) {
			exception.printStackTrace();
		}
		
		new Messages().compose(user, username_of_recipient, "this is the title", "the message", "", "");
	}
