Gallery-dl: [Suggestion] EH JSON from API

[w158297]

Would it be possible to add an option to let the JSON data written for E-Hentai downloads be from their official API? https://ehwiki.org/wiki/API
The current implementation sadly leaves out a lot of data, although it provides information about Parent/ visibility which the API doesn't.

Also gallery-dl -j $gallery_page option for EH galleries starts going through all the pages instead of just showing the one for the requested URL

leaves out a lot of data

"archiver_key", "category", "thumb", "uploader" "rating", and "torrentcount" from what I can tell. And the total file size is only an rough estimate. Everything else just has a different name.
"category", "thumb", "uploader" "rating", and "torrentcount" would be easy enough to get from the gallery HTML page as well, only "archiver_key" would be missing.

I wouldn't mind adding an option to (also) get the metadata from the API, but that's 1 extra HTTP request which might not be necessary.

Also gallery-dl -j $gallery_page option for EH galleries starts going through all the pages instead of just showing the one for the requested URL

Use -K or -j --range 0

That would also work, thank you very much!

… from what I can tell

Also if there are torrents it gives you the hash,name, torrent+file size for them. Additionally the upload time is missing seconds, which doesn't matter I guess.

On a side note, about the current gallery-dl JSON: what is the "subcategory" entry referring to?
(and for some reason there are the two entries for language entries)

now that we are adding more info from the EH-api, its possible to redownload only the metadata for those ?

Extracting a gallery_id wasn't the problem, but all format strings still expected the old metadata names, e.g. gallery_id instead of gid from the API. I've now renamed the old metadata fields to match their API counterparts, so this doesn't happen anymore (https://github.com/mikf/gallery-dl/commit/61fbbd2dae68a4ed10751c9eb783d4ddde479537) and the metadata option is now a simple boolean value.

@hellupline I recommend --range 0 to skip all images, but this will still cost 1 image limit point per gallery.
