Hello @800a7b32, thanks for the PR! Seen that this is a bit important changes, I would require to check deeper your code changes, will do that as soon I will have some spare time and provide feedback on the code.

Thanks again!

Thanks again, see my feedback, will do a test for the prawn creation and let u know

[damoiser]

thanks for the PR! I would find better to pass an additional params directly in the qr_params variable, you can add a new parameter there called [:output][:prawn][:pdf], so we can leave all prawn objects under that place. Or eventually we can create a new section for the inputs like "[:format_inputs][:prawn][:pdf]"

[damoiser]

why was this removed?

[damoiser]

thanks for this, I would need to test it accordingly

[damoiser]

If I may add some input: I would recommend replacing QRPRAWNLayout with a prawn extension module like so https://prawnpdf.org/docs/0.11.1/Prawn/Document.html#method-c-extensions (e.g. call it QRBills::PrawnExtension).

With this there is no need for additional params and layout logic and one can just simply add the extension and use it within their pdf workflow.

An example:

  Prawn::Document.extensions << QRBills::PrawnExtension

  Prawn::Document.generate("foo.pdf") do
    qr_bills_payslip(qr_bills_params)
  end
