Run diff against an uncommited file

[leovinsen]

Hi guys, thanks for the amazing product! I'm in the middle of POCing for my company's documentation needs. Deployment works well, but diff is not fully suited for my use case.

I am not committing the specs file into our repository and instead generate it in our CI workflow. Is it possible to run diff against the actual file inside the Github Action runner, similar to how deployment works?

name: diff OpenAPI
on:
  pull_request:
    branches:
      - development
jobs:
  api-diff:
    if: ${{ github.event_name == 'pull_request' }}
    name: Check API diff on Bump.sh
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v3

     - name: Generate OpenAPI specs
        run: // script to generate OpenAPI specs in ./openapi.json
        
      - name: Comment pull request with API diff
        uses: bump-sh/github-action@v1
        with:
          doc: <doc>
          token: ${{ secrets.BUMPSH_SECRET }}
          file: openapi.json
          command: diff
        env:
          GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}

Hi @leovinsen,

Thanks for your message!

If I understand correctly your provided action workflow, you would like to compute a diff between an already published documentation on bump.sh (your <doc> documentation slug + BUMPSH_SECRET token) and a generated openapi.json from the CI workflow. Is that correct?

It does sound like a legit use case which should already work with the current version of our GH action.
Could you show me the logs of the action run which doesn't work as you expect please?

Hi @paulRbr thanks for the quick response!

Yes that's correct, I would like to diff the currently deployed docs against a generated openapi.json inside the CI workflow. Something similar to bump diff openapi.json --doc <doc> --token <token> using Bump CLI.

Here is the logs:

Run bump-sh/github-action@v1
  with:
    doc: <doc>
    token: ***
    file: openapi.json
    command: diff
    fail_on_breaking: false
  env:
    GITHUB_TOKEN: ***

/usr/bin/git restore -s 6339eecfb67991bc22a9878ca3802e1406c2c309 .
No diff found, nothing more to do.

I observe that it checks out from 2 branches and then performs comparison on the two openapi.json file found on both branches. To test my theory:

• I tried removing the step that generates openapi.json, and it fails for deploy but not diff
• I tried commiting openapi.json, and it finally printed the diff results on my PR

Hi @leovinsen,

Sorry for the late reply. I took some time to try this out and I can't seem to reproduce the error with a generated API definition file.

Here's my test on our examples repo: https://github.com/bump-sh/examples/pull/35/files which lead to a correct diff.

Could you try to reproduce on a public repo so I can see both the git repository, the action workflow and the action logs?

Thanks a lot for your help 🙏
