Reproducible command

mangadex-dl "cover:https://mangadex.org/title/a6bfedbc-9846-4a97-9fcb-77a426d978e6/ubunchu"

Additional context

The command works when I'm checked out on older version (v2.9.0) , which was the version that introduced the "cover:" feature.

Starting from v2.10.x volume covers locale are now following --language value by default. It seems the manga didn't have English covers so it should throw error. But i forgot to put error handler for "cover" command for this case. Sorry about that.

NOTE: If you set --volume-cover-language, the covers will looking for locale from --volume-cover-language instead of --language

I've made PR #83 to fix this, you can test it by installing development version.

Installation with git + pip:

pip uninstall mangadex-downloader
pip install git+https://github.com/mansuf/mangadex-downloader.git@6d4e93b6acd104ca03bdc23d81c91bd7f3a7314e

Let me know if you have problem during installing and testing this patch 😉

---

If you want to show all covers, you can use all language

For example:

mangadex-dl "cover:https://mangadex.org/title/a6bfedbc-9846-4a97-9fcb-77a426d978e6/ubunchu" --language "all"
