A super simple diff checker for your GitHub workflow.

Very simple, you provide the action with a path to a file or folder, and it tells you if the file was added, modified, removed, or renamed. It will also output the items name and previous name, particularly usefull if it was just renamed.

• Usage
• Inputs
• Outputs
• Example Case

- name: Simple Diff
  uses: mudlabs/simple-diff@v1.2.0
  with:
    path: path/to/file   

You have a workflow that only runs on a push event to a file path. But you don't want it to run if the file was removed (deleted).

• Note: In this example we do not specify the path property. If your workflow is conditioned to only run when changes to a given path occure, you don't need to provide the action with the file path. (assuming that's the file path you want to check).

name: My File Workflow

on:
  push:
    paths:
      - path/to/my/file.ext

jobs:
  diff:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Simple Diff
        uses: mudlabs/simple-diff@v1.2.0
        id: diff
      - run: exit 1
        if: steps.diff.outputs.removed == true
  
  # Other jobs will run only if file.ext was NOT removed.
