Here are some code snippets for various programming languages (complete with completely unnecessary comments) showing how you can interface with Apertium by means of D-Bus. You'll need to install the D-Bus service for Apertium.

Python

#!/usr/bin/python
# coding=utf-8
# -*- encoding: utf-8 -*-

import dbus, sys, codecs;

sys.stdin = codecs.getwriter('utf-8')(sys.stdin);
sys.stdout = codecs.getwriter('utf-8')(sys.stdout);

mode_name = 'en-af'; # The name of the installed mode

bus = dbus.SessionBus(); # Create a new session bus

# Get the translator
translator = dbus.Interface(bus.get_object('org.apertium.mode', '/'), 'org.apertium.Translate'); 

input = sys.stdin.read(); # Read the data

print translator.translate(mode_name, {}, input); # Print the translation

Java

import org.freedesktop.DBus;
import org.freedesktop.dbus.DBusConnection;
import org.freedesktop.dbus.exceptions.DBusException;

import org.apertium.Info; // The interface we use to access org.apertium.info/

class TestDBus {

        public static void main(String[] args) throws org.freedesktop.dbus.exceptions.DBusException {
                DBusConnection bus = null;
                Info info = null;

                bus = DBusConnection.getConnection(DBusConnection.SESSION);
                info = bus.getRemoteObject("org.apertium.info", "/", Info.class);

                for (String s : info.modes()) {
                        System.out.println(s);
                }

                bus.disconnect();
        }
}

We have a guide on installing the Java D-Bus bindings and a guide on compiling a small Java application which uses an Apertium D-Bus service.
