Why is this necessary? Shouldn't fetchzip take care of the unpacking?

Thanks for reviewing!
Hm. I modeled the PR after #78409 and other fonts do the same thing, e.g. yanone-kaffeesatz or ubuntu-fonts. But that doesn't mean it's correct 🤔
I think this overrides the postFetch defined by fetchzip, which is where the unpacking takes place. So it has to be done manually. But I concur, it's weird.

Yeah, it seems very weird. If we're unzipping manually anyway, we might as well use fetchurl.
Maybe this should use mkDerivation instead, disable the unnecessary phases (mostly build) and do the installation in installPhase. I don't have much experience with fonts in nixpkgs though. @marsam, what are your thoughts on this?

(Its possible I won't be able to react to emails over the rest of the weekend. So if someone else wants to merge, no need to wait for my approval)

@puzzlewolf according to the docs, you should just add unzip to nativeBuildInputs, see: https://nixos.org/nixpkgs/manual/#ssec-unpack-phase .

@doronbehar Do you want me to model this after e.g. nafees? It's quite different from e.g. ubuntu-fonts, it uses mkDerivation instead of fetchzip. Do you know of a community-agreed default way of doing this kind of font packages?

I can see that we have many fonts installed with fetchzip which is a bit unfortunate since this has the disadvantage that it makes it impossible to override these derivations with <font>.overrideAttrs. nafees is written great so yes, please.

Done, now it uses mkDerivation.

And now it's fixed-output. It should be, right? The manual seems pretty clear: https://nixos.org/nix/manual/#sec-advanced-attributes, but fixed-output derivations seem to be their own can of worms NixOS/nix#2270. |

If there's anything else you would like me to take a look at (a PR of yours or one you have reviewed), let me know. No guarantees of course. |

Thanks for reviewing, explaining and your receptiveness on discourse 🚀. Currently, there is only #83028, which should probably also go the I wonder if we should document somewhere in the manual that |
|
Yes, I think #83028 could be modeled after this PR. Documentation would be great! Are you up to writing that? I think the ´fetchX` functions are pretty much just intended to be used as part of a package, but never as the top-level package. If you feel up to it, you could write some documentation. We can then look for some people who have contributed |
