As already mentioned in #1682 I would like to offer help with this. I already looked at the your changes, but I still have some questions:

  • It seems that this PR depends on some unpublished changes in pydyf. I made my own version of pydyf to make this branch work, but I had to disable some things as the resulting PDF was broken. I am not sure if its due to the changes here, or if I forgot some adjustments in pydyf. Would you mind publishing your current progress with pydyf?
  • The tagging seems to work mostly fine but the structure tree and parent tree references are apparently not completely valid. Are you working on this right now?
  • What are the next steps in your opinion? Do you have a specific roadmap what to tackle next? I don't want to do things in parallel again. ;)

@flintflump Thanks a lot for your help.

  • It seems that this PR depends on some unpublished changes in pydyf. I made my own version of pydyf to make this branch work, but I had to disable some things as the resulting PDF was broken. I am not sure if its due to the changes here, or if I forgot some adjustments in pydyf. Would you mind publishing your current progress with pydyf?

Sorry, we forgot to push the changes. It’s done (on master).

  • The tagging seems to work mostly fine but the structure tree and parent tree references are apparently not completely valid. Are you working on this right now?

We’ll be working for a client on this topic during August. We’ll first try to make everything work for his needs, so things will probably change during the next days/weeks (including tests).

  • What are the next steps in your opinion? Do you have a specific roadmap what to tackle next? I don't want to do things in parallel again. ;)

Adding unit tests, refactoring and cleaning (we have dirty code that may lead to broken structures, we know that). Including #1695 could also be interesting. Then we’ll test our client’s documents and be sure that everything works fine. So it’ll be probably easier to work in parallel when everything is OK for our client, in a few weeks.

print/py-weasyprint: Update to 59.0.
c82b5df 
Version 59.0
------------

Released on 2023-05-11.

below.

* `#1864 <https://github.com/Kozea/WeasyPrint/issues/1864>`_:

Version 59.0b1
--------------

Released on 2023-04-14.

**This version is experimental, don't use it in production. If you find bugs,
please report them!**

Command-line API:

* The ``--optimize-size`` option and its short equivalent ``-O`` have been
  deprecated. To activate or deactivate different size optimizations, you can
  now use:

  * ``--uncompressed-pdf``,
  * ``--optimize-images``,
  * ``--full-fonts``,
  * ``--hinting``,
  * ``--dpi <resolution>``, and
  * ``--jpeg-quality <quality>``.

* A new ``--cache-folder <folder>`` option has been added to store temporary
  data in the given folder on the disk instead of keeping them in memory.

Python API:

* Global rendering options are now given in ``**options`` instead of dedicated
  parameters, with slightly different names. It means that the signature of the
  ``HTML.render()``, ``HTML.write_pdf()`` and ``Document.write_pdf()`` has
  changed. Here are the steps to port your Python code to v59.0:

  1. Use named parameters for these functions, not positioned parameters.
  2. Rename some the parameters:

     * ``image_cache`` becomes ``cache`` (see below),
     * ``identifier`` becomes ``pdf_identifier``,
     * ``variant`` becomes ``pdf_variant``,
     * ``version`` becomes ``pdf_version``,
     * ``forms`` becomes ``pdf_forms``.

* The ``optimize_size`` parameter of ``HTML.render()``, ``HTML.write_pdf()``
  and ``Document()`` has been removed and will be ignored. You can now use the
  ``uncompressed_pdf``, ``full_fonts``, ``hinting``, ``dpi`` and
  ``jpeg_quality`` parameters that are included in ``**options``.

* The ``cache`` parameter can be included in ``**options`` to replace
  ``image_cache``. If it is a dictionary, this dictionary will be used to store
  temporary data in memory, and can be even shared between multiple documents.
  If it’s a folder Path or string, WeasyPrint stores temporary data in the
  given temporary folder on disk instead of keeping them in memory.
