FFO is a simple formatting library, mainly target to be used with old systems that do not support xml or other types of messages.

Note that this is a very very small library, just aimed at somthing I needed and I couldn't find... well a library like this to do it.

Do you need this?

  • Do you need to deal with messages that have fixed length, regardless of the size of the fields?
  • Does content get padded with (tipically) spaces or zeros?
  • Do you have a size for the different fields in your message?

    If the answer to some or all of these questions is yes, this library might be for you.
