Convert covers to WebP, how?

[pixelfabs]

I like to convert my covers to WebP. WebP is supported since Hugo 0.83. I had a look at layout/partials/covers.html and assume it should be added to line 16 of covers.html

{{ printf "%s %s" (($cover.Resize (printf "%sx" $size)).Permalink) (printf "%sw ," $size) -}}

Hugo Docs says:

{{ $image.Resize "600x webp" }}

But I have no idea "where" I should add webp to covers.html.

Can someone point me in the right direction?

Replace: {{ printf "%s %s" (($cover.Resize (printf "%sx" $size)).Permalink) (printf "%sw ," $size) -}} with {{ printf "%s %s" (($cover.Resize (printf "%sx webp" $size)).Permalink) (printf "%sw ," $size) -}}

Which reminds me to make sure I did not forget to make that change in a personal fork after I did updates for sending upstream (here).

Excellent! Thank man :-)
It works just as intended.
