How to get Class from Action.ReturnType or Action.Parameters about ntypewriter HOT 3 OPEN

Ok, I think I have figured it out.

IType is a symbol and as such, I can assume that it has an attributes array and do a filter on it.

I have created a function like this:

{{- func typeName(type)
   	useType = Type.Unwrap(type)
	if (useType.ArrayType != null) 
	    useType = useType.ArrayType
	end
        typeAttrs = useType.Attributes | Array.Filter @AttrIsTypescriptType
        if (typeAttrs.size > 0)
             ret typeAttrs[0] | Custom.ExtractTypescriptType;
        end
	ret useType | Type.ToTypeScriptType
	end
}}
{{- func AttrIsTypescriptType(attr)
	ret attr.Name | String.Contains "TypescriptType"
	end
}}

first, I nwrap the type and extract the actual type if the type is an array type.
Then, I search the list of attributes for the symbol to find the TypescriptType attribute and if it exists, I use a custom c# function to extract the attributes parameter, which is it's name.
If the symbol doesn't have the TypescriptType attribute, I just return the Type.ToTypescriptType.

This seems to work well. I now just need to figure out how to do this on the parameter array.

It looks like you are getting there, but I really do not know why you prefer to do it in scriban instead of C#.

Hmm, that is a good point. I hadn't thought of doing it in C#. In my mind, the NTypewriter scripts are scriban and I was just locked into "do it in scriban". I will have to re-evaluate it. I think I could really simplify the scripts, and introduce better reuse if I did more in C#.

Thanks for the suggestion!
