Hello, I modified sankaku.py and idolcomplex.py. It now supports multi-page URL like https://chan.sankakucomplex.com/?tags=marie_rose&page=98&next=3874906 (NSFW).

Please review my code.

Thanks for your contribution.

As a general rule, you should check your code with flake8 and also add a test-case for your implemented feature.

In this case you should just add, for example

("https://chan.sankakucomplex.com/?tags=marie_rose&page=98&next=3874906", None),

to the list.

r"/\?(?:[^&#]*&)*tags=([^&#]+)"]
r"/\?(?:[^&#]*&)*tags=([^&#]+)"
r"((?:[^&#]*&)*page=([^&#]+))*"
r"((?:[^&#]*&)*next=([^&#]+))*"]

Instead of capturing every query-parameter on its own, capture the whole query string ((?:\?([^#]*)?) and parse it with text.parse_query(...)

... OK ignore this one. What I wrote wouldn't work. Just leave it as it is.

r"/\?(?:[^&#]*&)*tags=([^&#]+)"]
r"/\?(?:[^&#]*&)*tags=([^&#]+)"
r"((?:[^&#]*&)*page=([^&#]+))*"

Use util.safe_int(..., 1).
You don't need to check if this particular group is None, safe_int() already handles that.

Also don't unquote something that should be a number.

No space between condition and :. flake8 should tell you that as well.

Nice, thank you.

The only remaining issue is the regex, which now also matches the URLs of the other two extractors.
It should be fixed with some smaller changes and adding a $ at the end. Something like this should do the trick:

r"(?:https?://)?chan\.sankakucomplex\.com"
r"/?(?:\?([^#]*))?(?:#.*)?$"
