On most distros, all one has to do is download the <code>.AppImage</code> file, make it executable <code>chmod +x $AppImage</code>, and execute it. This doesn't work in NixOS out of the box though, as AppImage files usually (if not always) depend on certain libraries commonly found on other Linux distributions to exist on certain paths; such as <code>/lib64/ld-linux-x86-64.so.2</code>.

AppImage is a monolithic packaging format for linux applications. It contains all dependencies in one file that is composed of an executable with a tacked on filesystem.

使い方

実行

ほとんどのLinuxディストリビューションでは、.AppImageファイルをダウンロードし、それを実行可能ファイルchmod +x $AppImageにして実行するだけです。ただし、AppImageファイルは通常(常にではないにしても)ハードコードされたパス内の特定のシステムライブラリに依存するため、NixOSではそのままでは機能しません。

$ nix-shell -p appimage-run
$ appimage-run path/to/application.AppImage
Appimage apps cannot access host fonts, icons and themes
Additional Packages

Some appimages still have issues, so you can override for additional pkgs such as

programs.appimage.enable = true;
programs.appimage.binfmt = true;
programs.appimage.package = pkgs.appimage-run.override 
{
  extraPkgs = pkgs: 
  [
    pkgs.icu
    pkgs.libxcrypt-legacy
    pkgs.python312
    pkgs.python312Packages.torch
  ]; 
};

パッケージング

nixpkgs manual on wrapping AppImage packagesを参照してください。要するに、AppImageが抽出され、依存関係がnixビルド依存関係として追加されます。 次の例は、AppImageとしても配布されているプログラム、Qubaの派生です。

{
  lib,
  appimageTools,
  fetchurl,
}:

let
  version = "1.4.0";
  pname = "quba";

  src = fetchurl {
    url = "https://github.com/ZUGFeRD/quba-viewer/releases/download/v${version}/Quba-${version}.AppImage";
    hash = "sha256-EsTF7W1np5qbQQh3pdqsFe32olvGK3AowGWjqHPEfoM=";
  };

  appimageContents = appimageTools.extractType1 { inherit name src; };
in
appimageTools.wrapType2 rec {
  inherit pname version src;

  extraInstallCommands = ''
    substituteInPlace $out/share/applications/${pname}.desktop \
      --replace-fail 'Exec=AppRun' 'Exec=${meta.mainProgram}'
  '';

  meta = {
    description = "Viewer for electronic invoices";
    homepage = "https://github.com/ZUGFeRD/quba-viewer";
    downloadPage = "https://github.com/ZUGFeRD/quba-viewer/releases";
    license = lib.licenses.asl20;
    sourceProvenance = with lib.sourceTypes; [ binaryNativeCode ];
    maintainers = with lib.maintainers; [ onny ];
    platforms = [ "x86_64-linux" ];
  };
}


設定

AppImageファイルタイプをバイナリタイプとしてbinfmt_miscに登録する

You can tell the Linux kernel to use an interpreter (e.g. appimage-run) when executing certain binary files through the use of binfmt_misc, either by filename extension or magic number matching. Below NixOS configuration registers AppImage files (ELF files with magic number "AI" + 0x02) to be run with appimage-run as interpreter:

programs.appimage = {
  enable = true;
  binfmt = true;
};

この方法では、AppImageファイルを通常のプログラムのように直接呼び出すことができます。
