Arch Linux User Repository

@patlefort: Indeed, fixed in 8ce01347469d, thanks.

Your file comicthumb.thumbnailer contain an end-of-line character in the middle of the MimeType= entry, which cause it to fail to load:

(nemo:224849): CinnamonDesktop-WARNING **: 01:11:29.847: Failed to load thumbnailer from "/usr/share/thumbnailers/comicthumb.thumbnailer": Key file contains line “application/x-ext-cbr;application/x-ext-cbt;application/x-ext-cbz;application/vnd.comicbook-rar” which is not a key-value pair, group, or comment

@bluetail: please understand since Xfce/Thunar team do not provide a repository, the tumbler-extra-thumbnailers package on AUR is not strictly a 1:1 copy. I have harmonized the shell scripts for instance.
DjVu thumbnailer was added because it was requested (https://aur.archlinux.org/packages/tumbler-extra-thumbnailers?O=10#comment-792038).

In a5667f5083ea, I added the missing MIME type for .dds files, Thumbnailer for comic book archives and Thumbnailer for STL content.

@UnicornDarkness: Done. Thank you. Apologizing for what comes:

I chatted a bit with xfce / thunar people and they would recommend that the AUR package may follow with the current codebase.

The paths can remain the same, if pointing to ~/ that just means it can also be done non-globally. But it still works globally like before.

Are you able to update the code? I notice that djvu is not in that list, and I would leave it in for compatibility reasons.

Update

1 Customized Thumbnailer for .dds files
2 Customized Thumbnailer for folders
3 Customized Thumbnailer for text-based documents
4 Customized Thumbnailer for comic book archives
5 Customized Thumbnailer for webp content
6 Customized Thumbnailer for stl content

Thanks for your patience and devotion

@bluetail: I updated the script in 1c02ce6ac364, I hope the behavior is better.

PS: you posted your comment twice. Can you remove the older one which is lacking formatting, please?

Please stop removing thumbnails! This drove me insane.

Specifically, please remove

for directory in ".cache/thumbnails" ".thumbnails"; do
    for subdirectory in "normal" "large"; do
        rm -f "$HOME/$directory/$subdirectory/$THUMBNAIL"
    done
done

@dreieck: Done in ebe12846d971.

Please also add gnome-dds-thumbnailer to the conflicts and provides array (actually, gnome-dds-thumbnailer only installs that one file, so tumbler-extra-thumbnailers seems to be a drop-in replacement):

gnome-dds-thumbnailer: /usr/share/thumbnailers/dds.thumbnailer exists in filesystem (owned by tumbler-extra-thumbnailers)
Errors occurred, no packages were upgraded.

Regards!

@dreieck: Done in a9e7d48b818a.
