Add package: termux-gui-pm

Could be nice to add termuxgui==$TERMUX_PKG_VERSION here, since package will be auto-update I guess there could be a risk of risk github being updated before pypi, leading to pip install --upgrade termuxgui installing an older version (?)

[tareksander]

I'll make sure to only release updates to the apps when the update is already on pypi. $TERMUX_PKG_VERSION can't be used, since the library and all programs don't share the same version. I also though about packaging the python library as a Termux package, but the installation path changes with every minor version of python (e.g. /data/data/com.termux/files/usr/lib/python3.10/site-packages would change to /data/data/com.termux/files/usr/lib/python3.11/site-packages). Are there other python libraries packaged as Termux packages? How do they handle that? Could I ship the wheel in the package instead and reinstall it with a dpkg hook after a python upgrade to avoid dependency on the python version?

[Grimler91]

Revision of other python packages have to be increased when python is updated, so that they are install to the new path.

You could perhaps drop using pip all together and use the termux_setup_python_crossenv function to install termux-gui-pm from source into TERMUX_PREFIX, see for example python-apt for another fairly small python package that uses it

I looked how linux distributions deal with this, and on debian there is a directory /usr/lib/python3/dist-packages added to the python module search path where all python3 modules from apt packages are placed. If that was implemented for Termux, there would be no need to manually increase the revision to rebuild the packages after each python release. Debian seems to modify Lib/sysconfig.py for that with this patch. Is that a good idea? Should I create an issue for something like that?

[Grimler91]

Probably a good idea to discuss it, it would not work (I think) for packages with native libraries as (I guess) the ABI can change on major python updates, but for termux-gui-pm it should work so might be a good idea

[Grimler91]

Please use termux_setup_python_crossenv here as well, even if it is not strictly necessary (adviced by @xtkoba in #12576 (comment)), and then we can merge this 👍

[tareksander]

I copied the pre-configure function from other packages that use termux_setup_python_crossenv is that good enough?

[Grimler91]

I forgot that package doesn't have an setup.py or pyproject.toml file, and that we install in a debscript, so crossenv shouldn't be needed in this case, thanks!
