It might be nice if a future GWT 2.9.x release provides some rudimentary 
support for that procedure in preparation for J2CL. I'm not sure how that 
would look though. Maybe a way to specify extra .js files to be linked-in 
in the .gwt.xml file? Maybe a way to specify where the contents of those 
JavaScript files should be placed in the JavaScript namespace? Maybe a new 
GWT linker that outputs a single script file that runs in the same scope as 
the web page so that it doesn't require that $wnd stuff? Right now, I'm not 
sure how well blending external .js files with GWT2 actually works.

Re: GWT 2.9.0 release

[Colin Alworth]

There are sort of two categories of these - the ones on your JSOs, i.e. 
already native types, so you just want to describe the real JS API, except 
in terms that let you use it in Java, and cases where you need a util 
method to do something in JS that seemed difficult to do in Java. For the 
first, you mostly just add a @JsType(...) annotation, remove the JSNI body 
and make sure the method signature matches what will make sense in JS.

Here's an example of a class in com.google.gwt that has been ported, 
maintaining as much of its api as possible, while also now being compatible 
with J2CL:
Before: 
https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/typedarrays/client/DataViewNative.java
After: 
https://github.com/Vertispan/gwt-typedarrays/blob/master/src/main/java/org/gwtproject/typedarrays/client/DataViewNative.java


For the second case, with lambdas in Java 8 and jsinterop annotations, this 
is much simpler than it used to be. My standard approach is to remove the 
"native" keyword and "/*-", "-*/;" tokens, and then look for syntax errors. 
Most of my projects still assume Java 8 as a baseline, so "var" is a 
problem, but if you are using recent Java you can leave that in and just go 
after the other oddities.

For the most part, you can use Elemental2 types to get a pretty close-to-JS 
experience. Sometimes you'll need to "cheat" a bit with a Js.cast() or 
Js.uncheckedCast() to get to the matching type.

Here's an example where JSNI was probably not needed to begin with (and 
with the bug left intact for complete backward compatibility):
Before: 
https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/typedarrays/client/JsUtils.java#L47-L53
After: 
https://github.com/Vertispan/gwt-typedarrays/blob/master/src/main/java/org/gwtproject/typedarrays/client/JsUtils.java#L58-L64

Here's a more complex example - note that to achieve this, the odd annoying 
cast is required, as well as a new SAM interface, DOMImplStandard.Fn, which 
just has a onEvent(Event) method, and is marked as @JsFunction 
(https://github.com/treblereel/gwt-widgets/blob/master/gwt-widgets/src/main/java/org/gwtproject/user/client/impl/DOMImplStandard.java#L435-L440
 
for the source)
Before: 
https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/user/client/ui/impl/RichTextAreaImplStandard.java#L315-L353
After: 
https://github.com/treblereel/gwt-widgets/blob/master/gwt-widgets/src/main/java/org/gwtproject/user/client/ui/impl/RichTextAreaImplStandard.java#L324-L365

This could probably be made slightly more pretty, but the goal while 
porting this was to just get it done quickly (and as a result of these 
efforts, nearly all of gwt-user.jar in some way or another works in J2CL 
today).

Generally, your JSNI methods should be shorter than this, so it becomes a 
matter of knowing which tools are out there, and which parts of 
Java+JsInterop map nicely to which parts of JS. When you find something 
missing, 99% of the time it can be found in jsinterop-base - the Js class 
there provides a bit of extra glue for things that can't be expressed 
easily in both GWT2 and J2CL.


The really ugly way that Thomas was alluding to is moving JS to an external 
JS file, but this is not the path of least resistance, it may be brittle 
(unless you take great care to use JsInterop annotations to avoid renames, 
changes in the compiler could break how you reference Java), and it will 
not be GWT2 compatible any longer. Using JsInterop as the examples above 
show should be simpler, more correct, and let you finish most of your 
migration before you even glance at J2CL.

Congratulations on a big milestone and great news to hear for the plan to 
release more frequently. Is that just an intent or is it automated ?

Re: GWT 2.9.0 release

[Ahmad Bawaneh]

I forget to mention the generated project also include dominno-ui 
dependency, if you dont want it you can remove it, but it gives you the 
chance to test many of the GWT3/J2CL migrated modules.
and for quick support you can reach us at dominokit gitter channel  
or gwt gitter channel

Re: GWT 2.9.0 release

[Ahmad Bawaneh]

You can use domino-cli  to create 
a j2cl simple maven project, download and the proper package for your 
operating system from the releases page 
, then from the command 
line use the following command

dominokit gen app -t basic --j2cl -n sample -g com.foo


where sample is the name/artifactId of the generated project and com.foo is 
the group id

the generated project is similar to a generated GWT project from tbroyer 
archetype.

after the project is generated inside the root folder do 
mvn clean install

once the project is built you can run it in development mode 

in one terminal run 
mvn tomcat7:run -pl *-server -am -Denv=dev

to start the server

and in another terminal run

mvn j2cl:watch

access the running application from the browser through 
http://localhost:8080/

Happy J2CLing

Re: GWT 2.9.0 release

Congratulations on the release of 2.9.0.

Can anyone point me to a sample Maven pom.xml from which to begin a new GWT 
project?  I specifically want to be using J2CL, and I'm happy to use 
snapshot releases if required.  Thanks, Robin.

Thanks for the incredible amount of work you put into GWT, and for this 
release. Just tried it out, enjoyed replacing Lombok "var" with proper Java 
"var" :-)
