Flatpak module yaml file for PyMuPDF

[cbm755]

If anyone needs PyMuPDF as a dependency for a Flatpak, feel free to use this module:

https://github.com/flathub/org.plomgrading.PlomClient/blob/master/python3-pymupdf.yaml

My intention will be to update this after new PyMuPDF releases, although perhaps the above link will track whatever version Plom is pinned. If you update it first, please post below.

background

I needed this for the linked project, and found the usual tooling namely flatpak-pip-generator was trying to build PyMuPDF from source, which is a pain b/c then we need MuPDF from source etc etc.

Without this, my builds would fail like:

  PyMuPDF/setup.py:     PIP_EXISTS_ACTION: i
  PyMuPDF/setup.py:     PIP_BUILD_TRACKER: /tmp/pip-build-tracker-sbu00e44
  PyMuPDF/setup.py:     PLAT: linux-aarch64
  running install
  /usr/lib/python3.9/site-packages/setuptools/command/install.py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools.
    warnings.warn(
  running build
  running build_py
  running build_ext
  building 'fitz._fitz' extension
  swigging fitz/fitz.i to fitz/fitz_wrap.c
  swig -python -o fitz/fitz_wrap.c fitz/fitz.i
  error: command 'swig' failed: No such file or directory
  error: subprocess-exited-with-error

Instead I found flatpak/flatpak-builder-tools#296 (comment)
which showed me how to specify all the relevant wheels manually. thanks @real-yfprojects.

This involved a bunch of copy-paste so I thought I'd share it here for search engines to index for the benefit of others.

I have updated this for 1.20.2, same link as above.

[cbm755]

Updated again for 1.21.1.

[real-yfprojects]

Have you seen req2flatpak.py?

[cbm755]

very cool, will look into this next time I'm updating my Flatpak, or of course patches always welcome

flathub/org.plomgrading.PlomClient#79

[cbm755]

Thanks @real-yfprojects, I have started using that so I will not maintain my manually-generated .yaml any more.

If anyone was relying on that, I suggest:

pip install req2flatpak
req2flatpak --requirements pymupdf==1.21.1 --target-platforms 39-x86_64 39-aarch64 --outfile python3-pymupdf.json

The 39 refers to Python 3.9 which in my case is what my Flatpak base image is using. For example, for Python 3.10: ... --target-platforms 310-x86_64 310-aarch64

FYI: I think I could go further and use req2flatpak directly on my requirements.txt: maybe I'll do so on a future release.

Great! If you encounter any problem like missing yaml support, feel free to tell me or open an issue.
