The bumpversion-action is a GitHub Actions workflow that automates the process of bumping the version of a project. It allows you to easily increment the version number based on the specified bump type (major, minor, or patch) and push the changes to a specified branch.

• bump-type (required): The type of the bump version. Valid options are 'major', 'minor', or 'patch'.
• branch (required): The branch to push the changes to. Default is 'main'.
• github-token (required): The GitHub token used for authentication. This should be a secret. Default is GITHUB_TOKEN.
• release-title (not required): A title to be the base for the realase like Release v2.3 etc default value is ''.
• generate-notes (not required): true if you want to generate notes automatically , false other wise default value is true.

• new_version: The new version after the bump version.
• old_version: The old version before the bump version.

create a bumpver.toml or .bumpver.toml file in your project dir similar the one used in bumpver library like this one .

[bumpver]
current_version = "0.1.0"
version_pattern = "MAJOR.MINOR.PATCH"

# pattern of files in which version is mentioned.
[bumpver.file_patterns]
"pyproject.toml" = [
    'version = "{version}"$',
]

then create a workflow file in .github/workflows dir like this one

name: test bumpversion-action

on:
  workflow_dispatch:
    inputs:
      bump-type:
        description: 'Bump type'
        required: true
        options:
          - major
          - minor
          - patch
        default: 'patch'

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@v4
      with:
        persist-credentials: false # otherwise, the token used is the GITHUB_TOKEN, instead of your personal token
        fetch-depth: 0             # otherwise, you will fail to push refs to dest repo
    - name: bumpversion
      uses: ouhammmourachid/bumpversion-action@v1.1.0
      with:
        github-token: ${{ secrets.TOKEN_PAT }}
        bump-type: ${{ github.event.inputs.bump-type }}
