Translate objetive-c into ruby

Translate objetive-c into ruby

I am developing a Rubymotion app. I am using the pod
KNSemiModalViewController. How can I "translate" this Objective-C code
into ruby?
[self presentSemiViewController:semiVC withOptions:@{
KNSemiModalOptionKeys.pushParentBack : @(YES),
KNSemiModalOptionKeys.animationDuration : @(0.3),
KNSemiModalOptionKeys.shadowOpacity : @(0.8),
}];
