Feature Request: Pages #10

Closed jbellanca closed 2 years ago

I'd like to request a feature where you could specify the start and end page numbers, and have it just download those images. Would be very helpful to just grab the last 8 pages of an index, for example.

A very interesting feature, thanks @jbellanca. I'll try to implement it!

I second this. And ideally, a shorthand to fetch just a single page by its number.

Thank you for publishing this excellent tool, in any case.

Hi @gcerretani. I got inspired and ended up implementing this feature, along with a couple of other small things.

Feel free to merge in some/all of these changes, if you like.

You'll have to forgive me for switching CLI parsing to the Cloup library... I have already been looking for an excuse to play around with it, but also I didn't see a way to make optional (positional) arguments using argparse. Regardless, it should be easy enough to ignore that change.

Done on 7c40b4bc8185ee9fccce33af372fcb4b24e91630 (sorry for the bad issue reference on the commit message, 1 instead o 10!)

You can select the range using new command line options. For example:

antenati.py URL downloads everything.

antenati.py URL -f 0 downloads everything.

antenati.py URL -f 10 downloads everything starting from page 10.

antenati.py URL -l 11 downloads from first to page 11 excluded (11 pages, first index is 0).

antenati.py URL -f 10 -l 11 downloads from fome page 10 to page 11 excluded (1 page).

Also negative indexes can be used:

antenati.py URL -f -4 downloads only last 4 pages.

antenati.py URL -l -3 downloads eveything except last 3 pages.
