Some manga doesn’t get downloaded fully

[StaticVoidDev]

What happened ?

I tried downloading the following url: https://mangadex.org/title/d8323b7b-9a7a-462b-90f0-2759fed52511/dosanko-gal-wa-namaramenkoi But it only downloads 50 of the 102 chapters.

What did you expect to happen ?

I expected all the chapters to be downloaded.

OS version

Windows 11 21H2

App version

2.10.3

Installation origin

Github releases

Installation origin (other sources)

No response

Reproducible command

py -3 -m mangadex_downloader "https://mangadex.org/title/d8323b7b-9a7a-462b-90f0-2759fed52511/dosanko-gal-wa-namaramenkoi" --no-group-name --no-track --path D:\manga

Additional context

After looking at MangaDex it seems that the downloader only downloads third party translations and not the official release, I couldn’t figure out how to force it to download official release.

Those issues are to an external site so there's nothing for mangadex-dl to grab. This is detectable in the response from mangadex with the externalUrl property in the response for a Chapter or MangaFeed.

I'm not sure this would be considered a bug, necessarily. I believe the publisher works with mangadex in a way to give those issues away for free, so they're preferred over any scan groups.

Here's an annotated chapter response for one with externalUrl:

I know it’s not really a bug, but it was the most fitting github issue category. I was wondering if it would be possible for mangadex downloader to grab the Manga plus versions of chapters, so that I wouldn’t need to use Manga plus specific downloaders like mloader.

Well, the name of the application says it all. It's downloader for MangaDex only. It cannot download from other sites.

If i want to implement download from other sites, then i'm forced to change the name of application. But i don't have any interest doing that. Besides implementing all features from MangaDex is already painful for me.

can we grab this url and pass it to another application/script from mangadex-downloader?
