My Problem

I am developing a Python package consumed by several internal consumers in my company using their CI/CD pipeline. Therefore, it's important for them to know what is the latest version of the package so that they can install it if it has been changed. The package uses the classic PEP 440 SemVer structure, so I usually just update the minor number.

I'm using Git and GitHub, so every new commit to the main branch means a new version. I'm currently updating the version manually, which is error-prone and tedious. I'm looking for a way to automatically bump the minor version whenever I merge a PR to the main branch.

What Have I Tried

Manual version bump before the merge
Using bump2version - I don't know how to make it happen automatically on a merge to the main branch

My Question

How can I automatically bump the minor version of a Python package upon a PR merged to the main branch of a repo?

CodePudding user response：

Instead of using bump2version locally, you can add to your GitHub repostory the bump2version-action, which states:

Every time you merge something to main branch, you'll receive an additional direct commit to main that increments the version in version.md.

Example:

name: Bump version workflow

on:
  push:
    branches:
    - main

jobs:
  bump-version:
    name: Bump package version
    if: "!contains(github.event.head_commit.message, 'Bump version')"
    runs-on: ubuntu-20.04
    steps:
    - name: actions/checkout
      uses: actions/checkout@v2
      with:
          persist-credentials: false
    - name: current_version
      run: echo "current_version=$(grep '# version' version.md | cut -d ' ' -f3)" >> $GITHUB_ENV
    - name: FragileTech/bump-version
      uses: FragileTech/bump-version@main
      with:
        current_version: "${{ env.current_version }}"
        files: version.md
