# Generate Nix Hash

[![Github Workflow](https://github.com/Gerschtli/generate-nix-hash/workflows/build-test/badge.svg)](https://github.com/Gerschtli/generate-nix-hash/actions)

This action fetches the `.tar.gz` archive of the provided repository revision and creates a JSON file containing the revision and sha256 hash generated by `nix-prefetch-url`. As a consequence [`nix`](https://nixos.org/nix) is needed for this action as shown in the example below.

## Usage

Create `.github/workflows/test.yml` in your repo with the following contents:

```yaml

name: "Test"

on:

  pull_request:

  push:

jobs:

  tests:

    runs-on: ubuntu-latest

    steps:

      - uses: actions/checkout@v2

      - uses: cachix/install-nix-action@v8

      - uses: Gerschtli/generate-nix-hash@v1

        with:

          rev: c61573364694a68d9993c8b0fb603b29e7251d79  # commit id

          owner: Gerschtli

          repo: generate-nix-hash

          file: config.json

```

This produces a JSON file like:

```json

{

  "rev": "c61573364694a68d9993c8b0fb603b29e7251d79",

  "sha256": "1s0qrrin8ry9klvjaxj4hd3qlf3cayfisq8pn7idqddgcg0lc079"

}

```

See [action.yml](action.yml) for all options.

## Publish to a distribution branch

Actions are run from GitHub repos so we will checkin the packed dist folder.

Then run [ncc](https://github.com/zeit/ncc) and push the results:

```bash

$ npm run pack

$ git add dist

$ git commit -a -m "prod dependencies"

$ git push origin releases/v1

```

Your action is now published! :rocket:

See the [versioning documentation](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
