This code was used to built emacs:

By the way, has someone migrated from straight/elpaca package manager to nix/nixos packages installation? Am I right that the only things which I need to do is just write: :straight nil for every package in my config and then write the list of package to my nix config?

Optionally provide extra packages not in the configuration file.

  extraEmacsPackages = epkgs: [
    epkgs.cask
  ];

Is there a package to integrate eshell with nix-shell (nix shell ...) ?

I'm recently seeing the following warning on a native-compiling emacs from the emacs overlay on macOS:

⛔ Warning (native-compiler): libgccjit.so: error: error invoking gcc driver
