GWT Generators vs java annotation processing

[Tal Shani]

Hi group,

I was wondering if the preferred way these days is to implement generation using the java annotation API or GWT generators is the way?

Does SDM works with java annotations in the whole edit->save->refresh cycle like the GWT generators do?

[Thomas Broyer]

GWT itself won't run annotation processors (yet), but if your IDE runs them automatically on file save then it should work just as well as GWT generators.

I will be presenting something around that at GWT.create -> http://gwtcreate.com/#agenda-us_room1_event9

Hi Daniel,

Thanks for sharing gwtcreate link. I just refer this link and just get to know about this event.

Will this event vedio share anywhere who are not attend this event?

Thanks,

Bhumika Thaker

@Thomas

Sadly (?!) I use intellij which doesn't compile on save. 

maybe doing some gradle magic to listen to file system changes and compile with -proc:only?!

@Daniel

Will there be a video of that presentation?

Is this project going to be available soon? (nothing relavent when googling "gwt singular")

Thanks,

Tal

IntelliJ has auto make. You can enable it in the compiler settings. You might also need to File -> Synchronize to make generated classes visible in the IDE.

Thanks! 
It's great to learn new things :)

@Thomas:

That sounds like GWT will use annotation processing instead of generators in the future. Is it a good idea to start writing annotation processors as an alternative for generators in new projects?

If you ask for my (very personal) opinion, I'd say that if you can use an annotation processor, then go ahead and do it.

I believe there are still good use-cases for GWT generators (for example, annotation processors are not designed to have dependencies on non-Java sources –such as ui.xml, gss or properties files–, and GWT generators are run once per permutation and can generate code specific to that permutation; choosing the right code-path for a given permutation when generating code through an annotation processor wouldn't be as easy). On the other hand GWT generators require you to fully manage your inputs and outputs if you want to take full advantage of incremental builds and not slow down SDM.

[Frank Hossfeld]

Thanks for your response. I am contributing the mvp4g framework. The framework uses annotations for events, presenters views, etc and has not to deal with -ui.xml, -html, css -files. Everything is pure Java. I have rewritten the generators. Now they are using IncrementalGenerators. But, because, the framework rescans the whole application every time and then generates the code, SDM is not as fast as it could be. Thinking about your answer, I will think about changing mvp4g to use annotation processing. This could be a real speed up.
