Hi all,
I just pushed out gwt-places to
GitHub: https://github.com/tbroyer/gwt-places
This is a port of the PlaceHistoryMapper generator as an annotation
processor: I copied the code from GWT proper and replaced uses of
com.google.gwt.core.ext. with javax.lang.model. and
javax.annotation.processing; and code generation with JavaPoet.
The tests have been copied almost verbatim, only adapted to JUnit 4 and
compile-testing (along with Truth assertions and a bit of Mockito), and
Maven (using the maven-invoker-plugin to replace the GWTTestCase machinery
and trigger the annotation processor).
*This is more of an experiment for now*, in preparation for GWT 3.0 which
will nuke generators.
The annotation processor is triggered by the presence of the
@WithTokenizers annotation. It means that if you use
PlaceHistoryMapperWithFactory, you have to annotation your interface with
@WithTokenizers even if all your tokenizers come from the factory; just use
an empty list in this case: @WithTokenizers({}).
The annotation processor generates a class with the same name as the GWT
generator (i.e. the name of your PlaceHistoryMapper subinterface with an
"Impl" suffix), so you just have to replace
GWT.create(MyPlaceHistoryMapper.class) with new MyPlaceHistoryMapperImpl().
I also added a quick check of @Prefix annotations, but it'll only emit
warnings and won't fail the build.
The JAR is available in Sonatype OSSRH snapshots repository at
net.ltgt.gwt:gwt-places:1.0-SNAPSHOT; its only dependency is gwt-user.
It's an annotation processor, so usage will depend on your build tool.
Ideally you'd put it (along with gwt-user) in your "processor path" (e.g.
using the 'apt' configuration in Gradle with my net.ltgt.apt plugin
<https://plugins.gradle.org/plugin/net.ltgt.apt>), but if you can't (e.g.
if you're using Maven), just add it to your compile classpath.
Note that I only verified that the tests passed, I've not used it anywhere
(yet).
