HTML Content as init parameter

[bgisme]

I just started looking at Elementary. So I apologize if this is a dumb question.

It seems very straightforward when taking a swift property like an array of strings and using them in a defined html structure.

But what if I need to take html as a property?

Is this the correct way to do it?

The code compiles. I just don't know if this is the right approach.

Thanks in advance.

public struct MyDiv: HTML {
    public var features: [String]
    
    public var supplied: Content
    
    public init(
        features: [String],
        @HTMLBuilder content: () -> Content
    ) {
        self.features = features
        self.supplied = content()
    }
    
    public var content: some HTML {
        div {
            supplied.render()
            ul {
                for feature in features {
                    li { feature }
                }
            }
        }
    }
}

you almost got it right, but you need to make MyDiv generic over the type of supplied.
In your case, you are using the type Content, which is the associated type of the HTML protocol (ie: what var content returns) - that is why the swift type checker fails to figure out what is going on ; )
also, no need to call .render() in there.

you can see this in practice in the example project (under Examples/HummingbirdDemo/Sources/App/Pages.swift)

your snippet should look something like this:

public struct MyDiv<Supplied: HTML>: HTML {
    public var features: [String]
    
    public var supplied: Supplied
    
    public init(
        features: [String],
        @HTMLBuilder content: () -> Supplied
    ) {
        self.features = features
        self.supplied = content()
    }
    
    public var content: some HTML {
        div {
            supplied
            ul {
                for feature in features {
                    li { feature }
                }
            }
        }
    }
}
