If both pdf and epub are available, download only pdf #48

I noticed that there are several books which have both pdf and epub available. The current script downloads both, creating a lot of duplicate files. It would be nice to only download pdf if epub and pdf both are available.

A simple mode variable along with a check whether to download PDF + EPUB or only PDF(if available.)

I can work on this if that's ok?

Yeah, the change should be simple. Sounds good to me.

alexgand commented 4 years ago

@sinnytk yes, please, but make it simple.

sinnytk commented 4 years ago

@alexgand These are the different modes that I came up with. What do you reckon would be a better implementation, using command line arguments or asking for mode as input from the user?

0, download both (EPUB and PDF)
1, download PDF only (if not available, skip)
2, download EPUB only (if not available, skip)
3, prefer PDF (otherwise download EPUB)
4, prefer EPUB (otherwise download PDF)

Have a look at my PR #54, I have included command-line options to select PDF only, EPUB, only, or both.

alexgand commented 4 years ago

Implemented in PR #57, please try the new code, it is now much better!
