Progress information for doc to PDF conversion #432

Open deeplow opened 1 year ago

deeplow commented 1 year ago

We currently don't have a way to see progress information when converting a libreoffice document to a PDF.

However, we may be able to to use libreoffice's page-range option to do it in batches of N pages.

@apyrgio stated in a verbal discussion that this will probably introduce overhead since we are starting libreoffice multiple times.

A solution to that could be to use the unoserver, a tool that's made to solve this exact problem (it's available as a python package)

Nice find, and it makes sense to have it in mind for the #424. For the Qubes integration though, would it make sense to follow an iterative process, where we first tally the time LibreOffice takes to finish the conversion into the time it takes to separate the pages? Not accurate, I know, but it's a first step towards a working progress counter.

Yes, we can start with what we already have (fixed % for this step of the process) and later change to protocol to accommodate more granular progress information.
