GitHub Actions are so cool!
Check out our recording about them @ Ministry of Testing Abu Dhabi if you want a quick sneak peek, but today I want to self-advertise one of the reusable Actions I made for you. And it wasn’t hard at all, thanks to the way they work.
You have heard about Semantic Versioning, haven’t you? If you are a developer you probably know a lot of libraries using Semantic Versioning. Chances are, you even use it for your projects.
Sometimes during CI/CD in such projects, you need to take simple actions with versions: compare and parse them. E.g. you may want to check that a PR to the main branch increases the version ($new_version > $old_version) or you may want to create or update a v$major.$minor / v$major tag whenever you release your project.
This is what madhead/semver-utils is for! Just drop it into your workflow and use it for various operations with versions:
- uses: madhead/semver-utils@latest
id: version
with:
# A version to work with
version: 1.2.3+42.24
# A version to compare against
compare-to: 2.1.0
# A range to check agains
satisfies: 1.x
- run: |
echo "${{ steps.version.outputs.major }}" # 1
echo "${{ steps.version.outputs.minor }}" # 2
echo "${{ steps.version.outputs.patch }}" # 3
echo "${{ steps.version.outputs.build }}" # 42.24
echo "${{ steps.version.outputs.build-parts }}" # 2
echo "${{ steps.version.outputs.build-0 }}" # 42
echo "${{ steps.version.outputs.build-1 }}" # 24
echo "${{ steps.version.outputs.comparison-result }}" # <
echo "${{ steps.version.outputs.satisfies }}" # true
echo "${{ steps.version.outputs.inc-major }}" # 2.0.0
echo "${{ steps.version.outputs.inc-premajor }}" # 2.0.0-0
echo "${{ steps.version.outputs.inc-minor }}" # 1.3.0
echo "${{ steps.version.outputs.inc-preminor }}" # 1.3.0-0
echo "${{ steps.version.outputs.inc-patch }}" # 1.2.4
echo "${{ steps.version.outputs.inc-prepatch }}" # 1.2.4-0
echo "${{ steps.version.outputs.inc-prerelease }}" # 1.2.4-0
Yeah, it's basically a wapper around semver package, so the outputs may look familiar to you. But if you need more in your workflows — feel free to open an issue with a feature you’re missing.
I want this action to become a one-stop shop for working with semantic versions in your GitHub Actions workflows one day!
