Eric Milles commented on GROOVY-9510:
-------------------------------------
I found that the delegate needs to be set only once. So the contributions can
be simplified a bit:
{code:groovy}
def hasPrecondition = { annotatedBy(name('spock.lang.Requires') |
name('spock.lang.IgnoreIf') | name('spock.lang.PendingFeatureIf')) }
contribute(inClosure() & isThisType() &
enclosingClass(subType('spock.lang.Specification'))
& (enclosingClass(conditions: hasPrecondition()) | enclosingMethod(conditions:
hasPrecondition()))) {
for (AnnotationNode pre : conditions) {
def condition = pre.getMember('value')
if (condition.getCode().is(currentNode)) {
delegateType =
resolver.resolve('org.spockframework.runtime.extension.builtin.PreconditionContext')
provider = 'Spock framework'
return
}
}
}
contribute(inClosure() & isThisType() &
enclosingClass(subType('spock.lang.Specification'))
& (enclosingClass(annotations: annotatedBy('spock.lang.Retry')) |
enclosingMethod(annotations: annotatedBy('spock.lang.Retry')))) {
for (AnnotationNode retry : annotations) {
def condition = retry.getMember('condition')
if (condition.getCode().is(currentNode)) {
delegateType =
resolver.resolve('org.spockframework.runtime.extension.builtin.RetryConditionContext')
provider = 'Spock framework'
return
}
}
}
{code}
In this case, {{currentType}} is {{Class<TheSpecClass>}} in recent tooling
snapshots. At the moment, {{currentType}} is not used. But if it were (as we
discussed above) we'd need to check for {{Class<TheSpecClass>}} and
{{TheSpecClass}}. Otherwise there is a cross-compatible way to capture from
the {{enclosingClass(...)}} pointcut.
Could you add this to your "spk.dsld"? And possibly rename the file to
"spock_tests.dsld"?

> If you have an annotation with a closure field like for example this in Spock:
> {code:java}
> @Retention(RetentionPolicy.RUNTIME)
> @Target({ElementType.TYPE, ElementType.METHOD})
> @ExtensionAnnotation(RequiresExtension.class)
> public @interface Requires {
> Class<? extends Closure> value();
> }{code}
> you can use it like
> {code:java}
> @Requires({ os.windows }){code}
> But I see no way to add IDE-hints for that closure like
> {{@DelegatesTo(PreconditionContext.class)}} as it is restriced to parameters.
> It would be nice if you could also annotate annotation member methods (and if
> IDEs would then support that too).
