Deduce submodule update versions automatically

[alexgg]

The nested changelog support currently needs to be provided with the version range on the commit body, similarly to:

Update from to

This is cumbersome and does not work well with tools that automatically update submodule dependencies like renovatebot.

This commit keeps the legacy behaviour but will extract the version range from git metadata when not provided. This new behaviour can be used by specifyng a commit body similar to:

Update

Testing details:

• Fork a device repository on a test github account
• Install renovate on it
• Onboard and configure renovate with https://github.com/balena-os/renovate-config
• Fork versionist and deploy and npm package with my modifications
• Fork balena-versionist modify it to depend on ag-versionist and deploy an npm package
• Fork versionist github action and modify it to use the npm packages releases above
• Install the action in the device repository
• Configure the action with:

  
  name: Run versionist
  on:
  push:
  branches:
    - master

jobs:

versionist: name: Run versionist if: "!contains(github.event.head_commit.author.name, 'versionist')" # Ignore push events made by the service account runs-on: ubuntu-latest outputs: # (optional) Only if you want to use them in next jobs version: ${{ steps.versionist.outputs.version }} # version: project's version after running versionist updated: ${{ steps.versionist.outputs.updated }} # updated: true if the version has been updated steps:

• name: Checkout project uses: actions/checkout@v2 with: submodules: recursive fetch-depth: 0 # We need all commits and tags persist-credentials: false # Next step needs to use service account's token
• name: Run versionist id: versionist # (optional) Only needed if using outputs uses: alexgg/versionist@alexgg-nested-changelogs with:

  Provide your versionist service account details

  github_email: 'yoctocookbook2ndedition@lindusembedded.com'
  github_username: 'yoctocookbook2ndedition'
  github_token: ${{ secrets.GH_VERSIONIST_TOKEN }}

With the above, the device repostiory dependencies are updated and the changelog is nested correctly.
