Java version of the Atlas toolkit

Java logo

The Atlas toolkit is a library to handle web interfaces.

Hello, World!

Here's how a Hello, World! type application made with the Atlas toolkit looks like:

Little demonstration

For a live demonstration: http://q37.info/runkit/Hello.

Source code:

import info.q37.atlas.*;
import java.util.HashMap;

class Hello extends Atlas {
	public void handle( DOM dom, String action, String id )
	{
		String body = 
		"<div class=\"vcenter-out\">" +
		" <div class=\"vcenter-in\">" +
		"  <fieldset>" +
		"   <label>Name:</label>" +
		"   <input id=\"input\" maxlength=\"20\" placeholder=\"Enter a name here\"'" +
		"	 type=\"text\" data-xdh-onevent=\"input|Typing\"/>" +
		"   <button data-xdh-onevent=\"Clear\">Clear</button>" +
		"   <hr/>" +
		"   <h1>" +
		"    <span>Hello </span>" +
		"    <span style=\"font-style: italic;\" id=\"name\"></span>" +
		"    <span>!</span>" +
		"   </h1>" +
		"  </fieldset>" +
		" </div>" +
		"</div>";

		if ( "Connect".equals( action ) ) {
			dom.setLayout("", body);
			dom.focus("input");
		} else if ("Typing".equals( action ) ) {
			dom.setContent("name", dom.getContent(id));
		} else if ( "Clear".equals( action ) ) {
			if ( dom.confirm( "Are you sure ?" ) )
				dom.setContents( new HashMap<String,String> ()
					{{ put( "input", ""); put( "name", ""); }} );
		} else {
			throw new RuntimeException( "Unknown action '" + action + "' !!!");
		}
	}
	public static void main(String[] args) throws Exception {
		String head = 
			"<title>\"Hello, World !\" example</title>" +
			"<link rel=\"icon\" type=\"image/png\" href=\"data:image/png;base64,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\" />" +

TodoMVC

And here's how the Atlas toolkit version of the TodoMVC application looks like:

TodoMVC

For a live demonstration: http://q37.info/runkit/TodoMVC.

Content of the repository

The Atlas directory contains the Java source code of the Atlas toolkit, which is not needed to run the examples.

Atlas.jar is the file you have to reference in the classpath in order to use the Atlas toolkit in your own application.

All other directories are examples.

To run an example, go inside its directory (Blank, Chatroom…) and launch:

  • under Windows : java -cp .;../Atlas.jar <Name> (with semi-colon as classpath separator),
  • under other platforms : java -cp .:../Atlas.jar <Name> (with colon as classpath separator).

where <Name> is the name of the example (Blank, Chatroom…).

The Atlas toolkit is also available for:
