If you want to call python from D, you should be able to install
pyd with dub. Depending on your python setup, it should Just
Work. If python is set up weird (ubuntu), you will need to
generate some custom dub config and insert it in your dub.json.
look for generate_dub_config.py on github for the generation
part. or install pyd with pip and run python -m
pyd.generate_dub_config
after that, you should be good to go. some example usage off the
top of my head that probably doesn't compile:
py_init();
InterpContext context = new InterpContext();
context.pystmts(`
from mutagen.flac import FLAC
audio = FLAC("example.flac")
audio["title"] = "An example"
`);
auto audio = context.audio;
audio.pprint();
audio.save();

Perhaps you can go that route. http://stackoverflow.com/questions/145270/calling-c-c-from-python That question is the reverse, calling C from python, rather than calling python from C. I think PyD is really your best option. The problem with PyD's docs is that it's not obvious how to get to them from the github page. You actually have to go to the wiki page and then there's a link to older docs from Bitbucket or ReadTheDocs, but those links are broken. Here's the readthedocs page: http://pyd.readthedocs.org/en/latest/ You would actually be interested in something like: http://pyd.readthedocs.org/en/latest/embed.html
