dblatex @0.3.12_2 still needs Python 3.10

[ballapete (Peter "Pete" Dyballa)]

Since about one year Python 3.11 is the default, in a few days Python 3.12 will become it. Has now the time come to update this package?

pete 310 /\ port deps dblatex
Full Name: dblatex @0.3.12_2
Library Dependencies: texlive-latex-extra, texlive-latex-recommended, texlive-math-science, dejavu-fonts, ImageMagick,
                      docbook-xml, docbook-xsl-nons, docbook-xml-5.0, python310
pete 311 /\ port deps dblatex +mactex
Full Name: dblatex @0.3.12_2+mactex
Library Dependencies: dejavu-fonts, ImageMagick, docbook-xml, docbook-xsl-nons, docbook-xml-5.0, python310

Simply changing 310 to 311 causes a warning:

/opt/local/var/macports/build/_Volumes_Shared_macports-ports_textproc_dblatex/dblatex/work/dblatex3-0.3.12/setup.py:255: SetuptoolsDeprecationWarning: setup.py install is deprecated.

        Please avoid running ``setup.py`` directly.
        Instead, use pypa/build, pypa/installer or other

Using 312 causes build failure:

Traceback (most recent call last):
  File "/opt/local/var/macports/build/_Volumes_Shared_macports-ports_textproc_dblatex/dblatex/work/dblatex3-0.3.12/setup.py", line 15, in <module>
    from setuptools import setup
ImportError: cannot import name 'setup' from 'setuptools' (unknown location)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/local/var/macports/build/_Volumes_Shared_macports-ports_textproc_dblatex/dblatex/work/dblatex3-0.3.12/setup.py", line 18, in <module>
    from distutils.core import setup
ModuleNotFoundError: No module named 'distutils'

I guess for python312 we would need to use pep517 but dblatex is apparently incompatible with that; see [3593e1ca3bd419d0dd6d494dac11e24ab4cd7933/macports-ports]. I don't see any upstream bug report about that though.

I don't see any other package managers that currently build dblatex against Python 3.12 yet, either. All of the existing ones that build against Python 3.11 continue to use the setup.py method.

Upstream isn't very active. I don't think filing a ticket there will achieve much unless it comes with a patch. Personally, I don't know how to update a package to conform to PEP517.

​https://sourceforge.net/p/dblatex/patches/12/ provides a patch to build dblatex with Python 3.12 – could be with others too.
