Simplified examples.

[lscoughlin]

Can we get some simplified examples?

Right now, Example.java is huge and somewhat difficult to follow structure.

The API is a bit quirky and highly opinionated as it is... trying to unravel what all the bits do is proving more than a little challenging.

I agree in Example has remain also some outdated code. I will update it in near future.

There are other three example JLine apps: gogo, groovy-repl and graal. If you are looking something very simple to start with I will add here also a minimal JLine repl example:

import java.io.IOException;

import org.jline.reader.EndOfFileException;
import org.jline.reader.LineReader;
import org.jline.reader.LineReaderBuilder;
import org.jline.reader.UserInterruptException;
import org.jline.reader.impl.DefaultParser;
import org.jline.terminal.Terminal;
import org.jline.terminal.TerminalBuilder;

public class SimpleExample {

    public static void main(String[] args) throws IOException {
        Terminal terminal = TerminalBuilder.builder().build();
        DefaultParser parser = new DefaultParser();
        LineReader reader = LineReaderBuilder.builder()
                .terminal(terminal)
                .parser(parser)
                .build();
        while (true) {
            try {
                String line = reader.readLine("prompt > ");
                System.out.println(line);
            } catch (UserInterruptException e) {
                // Ignore
            } catch (EndOfFileException e) {
                return;
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

Example.java has been split in two.
Now usage of widgets, auto suggestions, object highlight printing and other advanced console features can be found at Console.java
