Cataclysm: Dark Days Ahead can be played with numerous mods, soundpacks, and tilesets. Currently, most of them are not yet provided in the official nixpkgs.

This nixpkgs overlay is an attempt to improve the situation; it provides extra mods, soundpacks, and tilesets not available in nixpkgs. It also provides derivations for the recent experimental builds, making it easier to try the bleeding edge of Cataclysm: DDA.

See the manual to install nixpkgs overlays in general. You can install this overlay under your ~/.config/nixpkgs for example:

cd $SOMEWHERE
git clone https://github.com/mnacamura/nixpkgs-cdda-mods.git
cd ~/.config/nixpkgs/overlays
ln -s $SOMEWHERE/nixpkgs-cdda-mods

After that, mods, soundpacks, and tilesets defined in the overlay will be visible in cataclysmDDA.pkgs.

If you'd like to use the overlay without polluting your environment, you can do something like this:

let
  nixpkgs-cdda-mods = builtins.fetchTarball {
    url = "https://github.com/mnacamura/nixpkgs-cdda-mods/archive/master.tar.gz";
  };
in

with import <nixpkgs> {
  overlays = [ (import nixpkgs-cdda-mods) ];
};

...

You can install Cataclysm: DDA with mods as explained in the manual. Example:

let
  inherit (cataclysmDDA) attachPkgs git pkgs;

  # `attachPkgs` is required after you applied `override` or `overrideAttrs`
  # to your C:DDA derivation. It fixes some incorrect attributes remaining
  # after overrides.
  myCDDA = attachPkgs pkgs (((git.tiles.override {
    version = "2020-11-03";
    rev = "97896c2bc98aac1d47f94ff92d0f43670365ef5a";
    sha256 = "1qv30g8ahdgrbbp1kalwnn51mfb66a41dqmm0xifgw6r0pf246fk";
  })).overrideAttrs (_: {
    enableParallelBuilding = false;
  }));
in
myCDDA.withMods (mods: with mods; [
  tileset.UndeadPeople
  soundpack.Otopack
])

The latest experimental build (as of the most recent update in this repo) is available at

# Tiles build
cataclysmDDA.jenkins.latest.tiles

# Curses build
cataclysmDDA.jenkins.latest.curses

Older experimental builds are also available, up to 60 builds from the latest to older. Example:

cataclysmDDA.jenkins.b11150.tiles

Note that these builds have no pre-built binaries. You need to compile them by yourself on your machine.

Cataclysm: Bright Nights, a fork of Cataclysm: DDA, is available at

# Latest tiles build
cataclysmBN.release.latest.tiles

# Latest curses build
cataclysmBN.release.latest.curses

# Older releases are also supported. For example, release 891:
cataclysmBN.release.b891.tiles

As of now, the following mods, soundpacks, and tilesets are available. If you know any mod, soundpack, or tileset that should be in this overlay, feel free to make an issue or pull request.
