lisp-packages.nix: update Nyxt

[jmercouris]

@7c6f434c

These are the changes I had to make to update Nyxt for NixOS.

Closes #127906

[7c6f434c]

Hmmm, so you need CL-WebKit2 fresher than the latest Quicklisp? Or would it be enough to run Quicklisp update?

(also, I think you said you expected an extra package to be needed)

[jmercouris]

We sometimes need cl-webkit2 fresher than the latest quicklisp. We need extra packages for 2.2.0, and 2.3.0.

[7c6f434c]

I am not exactly eager to edit generated files, and putting the real version into overrides sounds «update-forgetting-prone»… So I guess globally the way to go is to add cl-webkit2-nyxt in lispPackages that overrides the Quicklisp-converted version.

[jmercouris]

Perhaps that is the solution, in any case, I don't know how to make it happen. When 2.3.0 comes out I will ping you with the new dependencies and then we could do it at that time. I think that makes the most sense. What do you think?

Is there a way to locally override lispPackages with something like an overlay? I want to use a newer nyxt but since lispPackages is just an attribute set I'm not sure how to override nyxt and cl-webkit2.

[7c6f434c]

Well, you can use // { cl-webkit-2 = …; nyxt = …; }, as ot's not a deep override

[pjones]

@7c6f434c Oh, that's interesting. I didn't think the cl-webkit-2 change would propagate into the nyxt attribute. I'll give it a shot.

[7c6f434c]

@pjones you can always override, or even clone the expression and pass it whatever version you want. (Sure, it won't propagate per se, unless you do some magic)

[jmercouris]

@7c6f434c can you please remind me how I would test my local nixpkgs checkout/modifications?

I have cloned NixOS/nixpkgs, and made some changes, I then try to do:

sudo nix-env -i nyxt -I nixpkgs=/the/path/to/my/checkout

but for some reason it always ends up installing 'nyxt-2020-10-23'...

[jmercouris]

Nevermind, I found the answer here: https://nixos.wiki/wiki/Nixpkgs/Create_and_debug_packages

it seems my documentation was outdated.

[7c6f434c]

A proper Quicklisp update has happened since, and together with Nyxt update to a fresher version
