sc-jsonnet

Build your snapcraft.yaml with jsonnet!

Description

Use jsonnet syntax to build your snapcraft.yaml.

For information about jsonnet see https://jsonnet.org/

Howto

First you need to get sc-jsonnet from the snap store. Either run:

sudo snap install sc-jsonnet

Or click the following button to go to the store where you can install it using the GUI:

Get it from the Snap Store

Now you have the program you need to make a file called snapcraft.jsonnet in your snapcraft project at ./snap/local/snapcraft.jsonnet. Add the following to begin with:

local snapcraft = import 'snapcraft.libsonnet';

snapcraft {
    name: "my-jsonnet-snap-name",
    version: "0.1",
    summary: "Single-line elevator pitch for your amazing snap",
    description: "This is my-snap's description. You have a paragraph or two to tell the most important story about your snap. Keep it under 100 words though, we live in tweetspace and your description wants to look good in the snap store.",
    grade: "devel",
    confinement: "devmode",

    parts: {
        "my-part": {
            plugin: "nil",
        },
    },
}

Finally we need to run the translation step to convert the jsonnet into yaml for snapcraft to use. First, we run sc-jsonnet without any parameters to see the yaml that will be produced:

sc-jsonnet

Now we have verified that everything works, we can run with -o snap/snapcraft.yaml to save into your project snapcraft.yaml for the snapcraft tool to use:

sc-jsonnet -o snap/snapcraft.yaml
