checksum-action is a GitHub Action that generates SHA256 checksums for multiple files in your GitHub repository. It allows you to specify a pattern for matching files and optionally specify a suffix for the generated checksum files.

Inputs

`pattern`

Required The pattern used to search for files (glob format). For example:

pattern: "*.txt"

This would match all .txt files in the repository.

`suffix`

Optional The suffix to append to the generated checksum files. Default is checksum.

For example, given a file example.txt, if the suffix is set to checksum, the generated checksum file will be example.txt.checksum.

Example Usage

Here's a basic example that demonstrates how to use checksum-action in a workflow:

name: Generate Checksums

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      contents: write

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Generate checksums
        uses: Solratic/checksum-action@v1
        with:
          pattern: "<your folder>/*.txt"
          suffix: "checksum"

      - name: Commit changes
        uses: EndBug/add-and-commit@v9
        with:
          default_author: github_actions

This workflow will be triggered on a push to the main branch. It will:

Checkout the repository
Generate SHA256 checksums for all .txt files in the repository
Append .checksum to the generated checksum files.
You would see <your folder>/<file>.txt.checksum in your repository.
