# 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"
|
|
"desktop-legacy"
|
|
"gsettings"
|
|
"home"
|
|
"network"
|
|
"mount-observe"
|
|
"removable-media"
|
|
"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).
