Hi,
I would be supportive of making these changes for OpenLayers 3.0.
Thanks a lot for writing up this excellent explanation.
Agreed!

Best regards,

Hello Peter,
I have seen your ticket. OpenLayers 2.x can be compiled only with
SIMPLE OPTIMIZATION. Then the Closure Compiler is just another
minimizer, slightly better then JSMIN. No big deal, beside 20% smaller
file size for existing build process. ;-)
What I am suggesting with the blog post is to write the code of
OpenLayers 3.x in a way to allow ADVANCED_OPTIMIZATION of of the code.
This would bring:
- Much better code optimization - resulting in even smaller file size.
- Documentation with JSDoc Tags is validated and meaningful - code is
under better control
- Possibility to strip all unused parts of the OpenLayers library when
it is compiled together with the final application. No need to choose
in advance what functionality I want in the building profiles.
Dependencies are solved by the compiler automatically.
- Possibility to compile OpenLayers only for particular use - Mobile
WebKit browser, Quirks vs Standards mode, etc.
- Debugging with FireBug even for the compiled version of the source code.
- Generation of dynamically loadable modules, to speed up loading of
the library.
Details are in the blog post, including tips on how to do that - based
on our practical experience with Google Closure Compiler from another
projects. I can write also examples to demonstrate the described
features.
The question for community is mostly:
- Are we willing to follow the JavaScript Style Guide, which is
necessary for the advanced compilation: http://bit.ly/9lETMA
- Do we want to write the correct JSDoc tags according to:
http://bit.ly/3UNSlI
These are the decisions for OpenLayers 3.0, which should be done
before the one week active coding session is going to happen. BTW I am
keen to participate if it's going to be in Europe.

I set up a ticket on this subject a couple of weeks ago, as it didn't
seem to me to be limited to any particular version of OL and there's
no reason why people can't start using it for their builds
straightaway (though not mentioned in the ticket, I am also using GCC
for my proj4js builds, with similar results)

Dear OpenLayers developers,
I wrote a blog post which is summarizing what can the open-sourced
Google Closure Compiler do for OpenLayers 3.0, how it can be done and
what are the implications.
Let's discuss this subject with the community. I am keen to get a
feedback and know what people think about that.
Please read the blog post:
http://blog.klokantech.com/2010/12/closure-compiler-for-openlayers-3x.html
And send comments...
Regards,
Klokan Petr Pridal
P.S.
I promised Tim Schaub at FOSS4G in Barcelona to publish such a post,
but it took me a bit longer then I expected...
