Enabling Syntax Highlight for Velocity Files in Eclipse

Hi Forks,

I've been working with a new Greenbox module, which will allow Eclipse developers to use Greenbox Framework easier.

I that worked, I did a really nice thing, I associate a *.vm file with Java Editor, and in a few seconds I had Velocty Editor with All syntax highlight necessary to create and edit Velocity templates for Greenbox.

Take a look how to Enable it on your enviroment:

I hope this could be as useful as it was to me!

AppFuse Article

In that article,
Matt Raible, shows interesting reasons to use AppFuse.

In Brazil, a gret friend of mine : Paulo Jerônimo, which promotes very enthusiastics presentations in Brazil, in events such as JustJava(Biggest Brazilian Java Event) talking about AppFuse.

AppFuse is a really nice way to getting started a project, and there are a lot of people using it here in Brazil.

Mr. Raible, added Greenbox on Resources section, and We would like to say thanks by reference.

Hope you enjoy the article reading it here.

NetBeans Plugin: Janino Plugin

Now my friends at Summa are happy with opportunity of to edit and create with a real productivity for Janino files using NetBeans.

If you want donwload it click here The following images shows Janino in action:

Usign NetBeans Diff Module

Basically, when user generates a code by second time, the NetBeans will ask to him "Hey you did some changes in original file, would you like to see the diff between old file and new file you are generating?", If User presse "yes" button, The Diff module will appear to user.

To invoke the Diff Panel on NetBeans you can use something similar to following source code:

  DiffVisualizer diff = (DiffVisualizer) Lookup.getDefault().lookup(DiffVisualizer.class);
    DiffProvider dprov = (DiffProvider) Lookup.getDefault().lookup(DiffProvider.class);
    StreamSource src = (StreamSource) Lookup.getDefault().lookup(StreamSource.class);  
    DiffPresenter v = (DiffPresenter) Lookup.getDefault().lookup(DiffPresenter.class);
class MyInfo extends DiffPresenter.Info {
   private Difference[] differences; 
    
public MyInfo(String name1, String name2, String title1, String title2,
              String mimeType, boolean chooseProviders, boolean chooseVisualizers) {
    super(name1,name2,title1,title2,mimeType,chooseProviders,chooseVisualizers);
  }
  public void setDifferences(Difference[] adiff) {
     differences = adiff;
  }

  public Difference[] getDifferences() {
      return differences;
  }

  public Difference[] getInitialDifferences() {
      return differences;
  }

  public  Reader createFirstReader() throws FileNotFoundException {
    Reader f = new FileReader("/Users/edgarsilva/summa/dev/GreenboxBaseProject/web/WEB-INF/spring-context.xml");
    return f;
  }
  
  public  Reader createSecondReader() throws FileNotFoundException{
   
      
      String springContext = new String("");
      try {        
              springContext= ClassGeneratorBase.getInstance().generateSourceByTemplateName(getClasse(),"springContext",initializeGreenboxContextAndVariables(),"/templates");
      } catch (Exception e ) {
         e.printStackTrace();
      }
      
      return new StringReader(springContext); 
  }
    
    }
    
      MyInfo i = new MyInfo("old","new","old","new","text/xml",true,true);
        try {
            
            s1 =  new FileReader("/Users/edgarsilva/summa/dev/GreenboxBaseProject/web/WEB-INF/spring-context.xml");
        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
        }
            String springContext = new String("");
            try {        
                    springContext= ClassGeneratorBase.getInstance().generateSourceByTemplateName(getClasse(),"springContext",initializeGreenboxContextAndVariables(),"/templates");
            } catch (Exception e ) {
               e.printStackTrace();
            }
      
      s2 = new StringReader(springContext); 
    
 try {
    v = new DiffPresenter(i);
    
    v.setProvider(dprov);
    v.setVisualizer(diff);
    diffPanel.add(v,BorderLayout.CENTER);
      
 }catch (Exception e) {
    NbUtils.showMessage(e.getMessage());
 }

The main point, you should pay atention is the fact to extend the class DiffPresenter.Info , in order to allow it works correctlly.

Any different tip will be appreciated in the comments section.
