Not too sure what's going on here. Something important seems to have died with RuntimeError: Cannot understand pandocversion=3.1.8

Could it be that this project depends on an outdated version of pandoc?

Hi @greyltc

pandoc-xnos seems to not be in active development anymore. There is a solution. So you could give that a try. It's also possible to remove pandoc-xnos filters out of your wiki.py in case you don't need it.
here:

wikmd/src/wikmd/wiki.py

Line 309 in 33e1c0b

filters=['pandoc-xnos'])

and here:

wikmd/src/wikmd/wiki.py

Line 197 in 33e1c0b

format='md', extra_args=["--mathjax"], filters=['pandoc-xnos'])

An other option would be to downgrade pandoc to version 2...

Maybe we could find an alternative or we could write this functionality as our own plugin.

The patch that you've identified above from the pandoc-xnos page works for me (Python 3.12 on MacOS 14.5, installed with pip).

Within your virtual environment, run the command:

python -m pip install --force-reinstall git+https://github.com/tomduck/pandoc-xnos@284474574f51888be75603e7d1df667a0890504d#egg=pandoc-xnos

Perhaps it could be added to the installation instructions until a more thorough fix is available.

Could the usage of an abandoned package which does not work with current pandoc versions not get removed from the code?

@Linbreux

Owner

@johann-petrak, yes that would indeed be better. But we need a replacement for it or write our own plugin. Until then, I'd like to keep it

@johann-petrak
Copy link

ok, but I have to admit I do not understand why it should be kept ... removing this from the code until there is an alternate solution is just a small fix and would prevent all new users for having to 1) encounter the problem and either give up immediately or 2) figure out what is going on and 3) manually edit the source code (something not many non-developer people would want to do)
I already did this so it does not even impact me any more, but I think having this in the code will discourage quite a few people to continue using wikmd.

@johann-petrak How did you run it? since we integrated pypandoc-binary this issue should not happen anymore.

This way it should work:
https://linbreux.github.io/wikmd/installation/regular_install.html

@johann-petrak
Copy link

I did:

  • clone the repo
  • create a conda env
  • pip install -e .
  • run from command line using "wikmd"

Encountered the error, removed the mentions of pandoc-xnos from the wiki.py file and after that it worked.

@Linbreux

Did you already have pandoc version 3 installed? Version 2 should still work

@johann-petrak

Yes, there was/is a system-wide installation of pandoc version 3.1.3
