Github Commit Timestamp Tagger

This action met a very simple need I had that nothing else seemed to do: it generates a tag for commits on a branch where the tagname is composed of a base version and a timestamp.

Nothing fancy. Just a way to tag commits to, for example, a development branch so a build can be produced for each merge.

Inputs

• base_version - The root text to use when creating the tag; i.e., v0.5.0

Outputs

• tag_name - The generated tag; i.e., v0.5.0-20191204081223
• tag_hash - The commit hash for the tag.
• tag_time - The timstamp from the tag; i.e., 20191204081223

Usage

Add a workflow file like the following to your project:

name: "Tag commits on develop"
on:
push:
branches:
- develop
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Apply a tag to the new commit
id: create_tag
uses: mcpierce/github-commit-timestamp-tagger@master
with:
repo-token: "${{ secrets.GITHUB_TOKEN }}"
base_version: "v0.5.0"
- name: Use the tag in another step
run: echo ${{ steps.create_tag.outputs.tag_name }}
