Replacing Delimited Field Names With Field Content

The example below replaces field names delimited between { and } with the field content. E.g:

“This is a field with another field {name} inside”

The replaces “name” with the contents of field called “name”.

-- Searches a field called "name" for fields delimited
-- between { and } and replaces them with field content

str = field(name)
while str:match("{(.-)}") do
  word=str:match("{(.-)}")
  str = string.gsub(str, "{" .. word .. "}", field(word));
end
return str
