Hi Jens,
Thanks for the idea, I tried it but it did not lead to a change. Looking a
bit further into how the <set-property> and <extend-property> are handled
that actually makes sense: set-property modifies only the *allowed* values
of the property, but the code generating the values 'locale' is checked
again looks at the *possible* values, which are controlled by
extend-property.
Ultimately I now went with a custom generator, which looks like this:
import java.util.SortedSet;
import com.google.gwt.core.ext.TreeLogger;
import com.google.gwt.core.ext.UnableToCompleteException;
import com.google.gwt.core.ext.linker.ConfigurationProperty;
import com.google.gwt.i18n.linker.LocalePropertyProviderGenerator;
public class RestrictedLocalePropertyProviderGenerator extends
LocalePropertyProviderGenerator {
@Override
public String generate(TreeLogger logger, SortedSet<String>possibleValues
, String fallback,
SortedSet<ConfigurationProperty> configProperties) throws
UnableToCompleteException {
String original = super.generate(logger, possibleValues,
fallback,configProperties
);
// original is now "{ ... code returning locale }", so
// wrap that into a function, invoke it, and filter the result.
return "{" +
"var allowedLocales = {'en':1, 'fr':1 };" +
"var locale = function() " + original + "();" +
"while (locale && !(locale in allowedLocales)) {" +
" var lastIndex = locale.lastIndexOf('_');" +
" if (lastIndex < 0) {" +
" locale = null;" +
" break;" +
" }" +
" locale = locale.substring(0, lastIndex);" +
"}" +
"return locale || '" + fallback + "'" +
"}";
}
}
Not pretty, but avoids most of the mentioned issues at the cost of
duplicating my list of allowed values (which change very rarely), and
ignoring a warning from the GWT compiler to not include gwt-dev as
dependency.
Regards,
