Eclipse 4 Plug-in Development by Example : Beginner's Guide

By: Dr Alex Blewitt

Overview of this book

<p>As a highly extensible platform, Eclipse is used by everyone from independent software developers to NASA. Key to this is Eclipse’s plug-in ecosystem, which allows applications to be developed in a modular architecture and extended through its use of plug-ins and features.<br /><br />"Eclipse 4 Plug-in Development by Example Beginner's Guide" takes the reader through the full journey of plug-in development, starting with an introduction to Eclipse plug-ins, continued through packaging and culminating in automated testing and deployment. The example code provides simple snippets which can be developed and extended to get you going quickly.</p> <p>This book covers basics of plug-in development, creating user interfaces with both SWT and JFace, and interacting with the user and execution of long-running tasks in the background.</p> <p>Example-based tasks such as creating and working with preferences and advanced tasks such as well as working with Eclipse’s files and resources. A specific chapter on the differences between Eclipse 3.x and Eclipse 4.x presents a detailed view of the changes needed by applications and plug-ins upgrading to the new model. Finally, the book concludes on how to package plug-ins into update sites, and build and test them automatically.</p>

Time for action – writing the markup parser


First, the format of the markup language needs to be explained. The first line will be a title, and then subsequent paragraphs are blank-line separated. This can be translated into an HTML file as follows:

minimark source

Translated HTML

This is the title

A paragraph with some text

Another paragraph

<html><head><title>This is the title</title></head><body><h1>This is the title</h1><p>
A paragraph with some text
</p><p>
Another paragraph
</p></body></html>

Perform the following steps:

  1. Create a class called MinimarkTranslator in the com.packtpub.e4.minimark.ui package as follows:

    public class MinimarkTranslator {
      public static void convert(Reader reader, Writer writer)throws IOException {
        BufferedReader lines = new BufferedReader(reader);
        String line;
        String title = String.valueOf(lines.readLine());
        writer.write("<html><head&gt...
