+# pkgs.appimageTools {#sec-pkgs-appimageTools}
+
+`pkgs.appimageTools` is a set of functions for extracting and wrapping [AppImage](https://appimage.org/) files. They are meant to be used if traditional packaging from source is infeasible, or it would take too long. To quickly run an AppImage file, `pkgs.appimage-run` can be used as well.
+
+::: warning
+The `appimageTools` API is unstable and may be subject to backwards-incompatible changes in the future.
+:::
+
+## AppImage formats {#ssec-pkgs-appimageTools-formats}
+
+There are different formats for AppImages, see [the specification](https://github.com/AppImage/AppImageSpec/blob/74ad9ca2f94bf864a4a0dac1f369dd4f00bd1c28/draft.md#image-format) for details.
+
+- Type 1 images are ISO 9660 files that are also ELF executables.
+- Type 2 images are ELF executables with an appended filesystem.
+
+They can be told apart with `file -k`:
+
+```ShellSession
+$ file -k type1.AppImage
+type1.AppImage: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) ISO 9660 CD-ROM filesystem data 'AppImage' (Lepton 3.x), scale 0-0,
+spot sensor temperature 0.000000, unit celsius, color scheme 0, calibration: offset 0.000000, slope 0.000000, dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=d629f6099d2344ad82818172add1d38c5e11bc6d, stripped\012- data
+
+$ file -k type2.AppImage
+type2.AppImage: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) (Lepton 3.x), scale 232-60668, spot sensor temperature -4.187500, color scheme 15, show scale bar, calibration: offset -0.000000, slope 0.000000 (Lepton 2.x), scale 4111-45000, spot sensor temperature 412442.250000, color scheme 3, minimum point enabled, calibration: offset -75402534979642766821519867692934234112.000000, slope 5815371847733706829839455140374904832.000000, dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=79dcc4e55a61c293c5e19edbd8d65b202842579f, stripped\012- data
+```
+
+Note how the type 1 AppImage is described as an `ISO 9660 CD-ROM filesystem`, and the type 2 AppImage is not.
+
+## Wrapping {#ssec-pkgs-appimageTools-wrapping}
+
+Depending on the type of AppImage you're wrapping, you'll have to use `wrapType1` or `wrapType2`.
+
+```nix
+appimageTools.wrapType2 { # or wrapType1
+  name = "patchwork";
+  src = fetchurl {
+    url = "https://github.com/ssbc/patchwork/releases/download/v3.11.4/Patchwork-3.11.4-linux-x86_64.AppImage";
+    sha256 = "1blsprpkvm0ws9b96gb36f0rbf8f5jgmw4x6dsb1kswr4ysf591s";
+  };
+  extraPkgs = pkgs: with pkgs; [ ];
+}
+```
+
+- `name` specifies the name of the resulting image.
+- `src` specifies the AppImage file to extract.
+- `extraPkgs` allows you to pass a function to include additional packages inside the FHS environment your AppImage is going to run in. There are a few ways to learn which dependencies an application needs:
+  - Looking through the extracted AppImage files, reading its scripts and running `patchelf` and `ldd` on its executables. This can also be done in `appimage-run`, by setting `APPIMAGE_DEBUG_EXEC=bash`.
+  - Running `strace -vfefile` on the wrapped executable, looking for libraries that can't be found.

+# pkgs.snapTools {#sec-pkgs-snapTools}
+
+`pkgs.snapTools` is a set of functions for creating Snapcraft images. Snap and Snapcraft is not used to perform these operations.
+
+## The makeSnap Function {#ssec-pkgs-snapTools-makeSnap-signature}
+
+`makeSnap` takes a single named argument, `meta`. This argument mirrors [the upstream `snap.yaml` format](https://docs.snapcraft.io/snap-format) exactly.
+
+The `base` should not be specified, as `makeSnap` will force set it.
+
+Currently, `makeSnap` does not support creating GUI stubs.
+
+## Build a Hello World Snap {#ssec-pkgs-snapTools-build-a-snap-hello}
+
+The following expression packages GNU Hello as a Snapcraft snap.
+
+```{#ex-snapTools-buildSnap-hello .nix}
+let
+  inherit (import <nixpkgs> { }) snapTools hello;
+in snapTools.makeSnap {
+  meta = {
+    name = "hello";
+    summary = hello.meta.description;
+    description = hello.meta.longDescription;
+    architectures = [ "amd64" ];
+    confinement = "strict";
+    apps.hello.command = "${hello}/bin/hello";
+  };
+}
+```
+
+`nix-build` this expression and install it with `snap install ./result --dangerous`. `hello` will now be the Snapcraft version of the package.
+
+## Build a Graphical Snap {#ssec-pkgs-snapTools-build-a-snap-firefox}
+
+Graphical programs require many more integrations with the host. This example uses Firefox as an example, because it is one of the most complicated programs we could package.
+
+```{#ex-snapTools-buildSnap-firefox .nix}
+let
+  inherit (import <nixpkgs> { }) snapTools firefox;
+in snapTools.makeSnap {
+  meta = {
+    name = "nix-example-firefox";
+    summary = firefox.meta.description;
+    architectures = [ "amd64" ];
+    apps.nix-example-firefox = {
+      command = "${firefox}/bin/firefox";
+      plugs = [
+        "pulseaudio"
+        "camera"
+        "browser-support"
+        "avahi-observe"
+        "cups-control"
+        "desktop"

+        "x11"
+      ];
+    };
+    confinement = "strict";
+  };
+}
+```
+
+`nix-build` this expression and install it with `snap install ./result --dangerous`. `nix-example-firefox` will now be the Snapcraft version of the Firefox package.
+
+The specific meaning behind plugs can be looked up in the [Snapcraft interface documentation](https://docs.snapcraft.io/supported-interfaces).
