Version

GitHub action to generate version numbers based on current build

Inputs

version

Required version prefix to use

Example usage

uses: rabotaua/actions-version@main
with:
  version: 2.1

Action will generate VERSION environment variable which then can be used anywhere:

- run: echo $VERSION

Version consists of: [version].[build]-[sha]-[branch] so output will be 2.1.3-dfcc185-main

Also GITHUB_SHA_SHORT and GITHUB_BRANCH_SLUG are exported just in case

Build

npm run build

WARNING: neither parcel nor ncc do not work under Windows

If you have made changes you should commit both source and dist

Context

Because of how GitHub works underneath there are few tricky things around pull requests

For usual builds commits are here github.context.sha but for pull requests actual commits are here github.context.payload.pull_request?.head.sha

The same story for branch names, here is an example

For usual build:

github.context.sha = xxxxxx
github.context.ref = refs/heads/main

For pull request:

github.context.sha = yyyyyy # merge commit
github.context.ref = refs/pull/3/merge

github.context.payload.pull_request.head.sha = xxxxxx # expected commit
process.env.GITHUB_HEAD_REF = refs/head/main # expected branch
