How it Works code is really just a way to:

  • create the enviroment
  • create a document
  • generate the content
  • insert it within a document

So first we need to create the enviroment so that we don't generate a verbose code, we need to insert it into variable.

To create the enviroment we need a couple of things, first we import a library, which already save us a bunch of code in order to reference to UNO. The next step is to choose the fomat element we will need to input. For tha we use the uno.getConstantByName and point to the ControlCharacter component which includes all the format we need.

  • Paragraph Break
  • Line Break
  • Hard Hyphen
  • Soft Hyphen
  • Hard Space
  • Append Paragraph
