Is there a smarter way to change only one field value of a tuple?

There is also sugar for this:
    
    
    import sugar
    
    var
      frameTextDefaults = (
        author: "Thomas",
        version: "unknown")
    
    frameTextDefaults = frameTextDefaults.dup:
      author = "Ralf"
    
    echo frameTextDefaults
    
    
    Run
