\startluacode
interfaces.implement {
     name      = "Hashtag",
     public    = true,
     protected = true,
     arguments = "string",
     actions   = function(str)
         context("{\\nohyphens\\letterhash %s}",string.gsub(str," ","_"))
      -- str = string.gsub(str," ","_")
      -- context.bgroup()
      -- context.nohyphens()
      -- context.letterhash()
      -- context(str)
      -- context.egroup()
     end
}
\stopluacode
