Calibre

From NixOS Wiki

Calibre is program to view, edit, convert and print ebooks.

This page is intended to explain how to run calibre in nixos.

.cbr and .cbz files

If you want to open .cbr and .cbz files, you need to add the following lines to your configuration.nix file:

/etc/nixos/configuration.nix
environment.systemPackages = with pkgs; [      
  (calibre.override {
    unrarSupport = true;
  })
]
Note: calibre requires several unfree packages to open .cbr and .cbz files. If you are using allowUnfreePredicate you will need to ensure that your configurations permit all of them.
{
  nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
    "calibre"
    "unrar"
  ];
}
