Hi,
How can we pass data (from validator)to quick fix ?

for instance,
I use the error() to issue the error INVALID_NAME
and @fix handles the error. how can we handle the error with data passed from error?

sincerely

Hi,

i am not quite sure what you are targeting with this question
the error methods in the validator have a String... varargs
param that allows you to pass data.

These will be available via org.eclipse.xtext.validation.Issue.getData()
in the quickfix provider

Ok thanks Christ.
I once use the quickfix in java, but now the xtext changes the source file into xtend and it seems that the syntax which works in java no longer works in xtend: the new ISemanticModification{} is not recognized.
can you give the equivalent codes to these:

acceptor.accept(issue, 'tag error', 'no tagsdfs', '', new ISemanticModification{
public void apply(final EObject element, IModificationContext context) {
createDefaultValue((KeyValuePair) element, "a");
}
})

Thanks.

Hi,
anonymous inner classes a not a feature of xtend. you can use a closure instead

acceptor.accept(issue, 'tag error', 'no tagsdfs',[object, context|createDefaultValue((KeyValuePair) element, "a")]);

HI, then where can i find the tutorial/example for this new syntax ?
Xtext 2.4.2 Documentation seems a little old-fashion~

Thx

Hi,

you are not forced to use xtend. you can configure the workflow to use java (though it may not work for all cases)

...
var generateXtendStub = false

Workflow {
...

So when i set
generateXtendStub = false

I switch to edit java code in xtend-gen folder, right?

No,

simply delete the xtend class, rerun the workflow and you should get a new java class in the src folder

It seems that content assist and validation are still in xtend.

jepp,

this is what i meant with "it may not work for all cases"
you have to replace the fragments with
- org.eclipse.xtext.generator.validation.JavaValidatorFragment
- org.eclipse.xtext.ui.generator.contentAssist.JavaBasedContentAssistFragment
