Eclipse Setup

After checking Tessell out of git, there are two main projects, tessell-user and tessell-dev.

tessell-user uses annotation processing to generate some event classes, which is unfortunately kind of janky to setup in Eclipse.

1. Install the Gradle Eclipse plugin

• This is not strictly required, but the checked-in .classpath/.factorypath files assume this setup

2. Go to Window / Preferences / Java / Build Path / Classpath Variables

• Add GRADLE_REPO has /yourHomeDir/.gradle/caches/modules-2

3. Import tessell-user and tessell-dev into Eclipse

• Gradle should download all the dependencies and put them onto the Gradle classpath container
• However, Eclipse needs to be "kicked" to see the annotation processor jar is now available

4. Close tessell-user
5. Open tessell-user
6. Clean tessell-user
7. Hopefully you have no build errors

Todo

• Add @Place annotation
  • Take name of presenter
  • Any constructor parameters--how to denote application-level vs. request-level?
• Figure out cross-presenter transitions
  • Event bus doesn't make sense--these aren't global things
  • Have Slot listen to presenter events?
• Support 2nd generation Presenter interfaces via event hook hints in ui.xml file
• form disable on ServerCall
• indicator on ServerCall
• Pre-fill the handler (optional);
• doLogin.call(user, pass);
• HasDispatchAsync to ServerCall cstr
• Out-of-the-box local storage integration (probably via changes to dtonator, use AutoBeans)
• PropertyGroup copies are not deep

Notes

• ResourcesGenerator assumes a global namespace of image/CSS files, even if you use subdirectories. It also assumes all image/CSS files are below the packageName you pass to it.

Binder DSL Ideas

• SetActions

  binder.when(...).is(true).set(//
    textOf(...).toOrElse("", ""), // toOrElse returns SetAction
    styleOf(...).to(bz.active())); // to returns SetAction
  
  binder.on(keyPressOf(...)).then(execute(command));
  binder.on(clickOf(...)).then(toggle(button));
  binder.on(clickOf(...)).set(SetAction...);
  binder.on(blurOf(...)).set(SetAction...);
  
  // or, for more unique static imports
  binder.on(blurOf(...), thenSet(textOf(...).to(asdf)));
  
  // string actions
  binder.when(condition, action1, action2);
  // e.g.
  binder.when(value, is(true), show(this), hide(that));
  

• Non-trivial omponents, e.g.

  <foo:Form>
    <fields>
      <foo:TextLine />
    </fields>
    <blah>
      <foo:Bar />
    </blah>
  </foo:Form>
  

  Goes to:

  form.addField(textLine1);
  form.setBlah(...);
  

  Any HTML implicitly becomes an HTMLPanel, e.g.:

  <foo:Form>
    <blah>
      <p>
        <foo:Bar />
      </p>
    </blah>
  </foo:Form>
  

  Goes to:

  form.setBlah(htmlPanel, List<Bar> bars);
