Oh right. It’s not really a bug, since the empty string is a valid base32 representation of the empty bytevector. >>> for example "" (an empty string).

Yes, it feels weird to me, the idea that an <origin> object with bogus values would be created just for the sake of satisfying the download tool. Wouldn’t the explanation in the manual of how to use this be relatively complex? That’s a good benchmark. >> What about, instead, providing an interactive function that would prompt >> for a URL, run ‘guix download’ on that, and emit an ‘origin’ template at >> point with all the info? > > I see several problems here, but the main is: this sounds like it should > be synchronous: you give an URL, wait until the source is downloaded and > finally get the template at point.

We want to welcome all human beings to our Guix party, don’t we? :-) Thanks, Ludo’.
