Trying to create a DSL that converts to HTML

render_html.moon

render_tags= (fn)->
        
        setfenv fn, setmetatable({}, {
         __index:(tag_name)=>
            print tag_name
            (opts)->
              build_tag(tag_name, opts)
        })
        fn!

buid_tag= (tag_name, opts)->
        buffer = {'<', tag_name}
        if type(opts) == "table"
          for k,v in pairs(opts)
            if type(k) != "number"
              append_all buffer, " ", k, '="', v, '"'
        if void_tags[tag_name]
          append_all buffer, " />"
        else 
          append_all buffer, ">"
          if type(opts) == "table"
            append_all buffer, unpack opts
          else
            append_all buffer, opts
          append_all buffer, "</", tag_name, ">"

        table.concat(buffer)
        print buffer

append_all= (buffer,...)->
        for i=1,select("#", ...)
         table.insert(buffer, (select(i, ...)))

class View
   new:=>
    render_tags(->@content!)

   content: => {
    layout {
       type: "vertical"
       text "hello"
