GitHub Action to retrieve the latest tag of any Git repo

Find Latest Tag

GitHub Action to find latest tag of any Git repository available on the Internet.

Examples

steps:
  - uses: tdemin/find-latest-tag@v1
    with:
      repo: https://github.com/tdemin/gmnhg.git
    # v0.4.0
  - uses: tdemin@find-latest-tag@v1
    with:
      repo: https://github.com/golang/go.git
      tag: '^go1'
    # go1.17.1

Usage

Inputs

• repo: required, Git URI of a remote to check tags from.
• tag: optional, regex to check tag names against (default "").

Private repository authentication is currently not implemented, although you can use the http://user:password@hostname.tld/repo.git URI notation for Git over HTTP(S).

Outputs

• tag: ${{ steps.STEP_NAME.outputs.tag }}

Errors

This action will fail if any of the conditions are met:

• Git is unable to ls-remote the repository;
• there are no tags in the repository;
• no tags are selected by the tag regular expression.

Sort order

Tags are sorted with sort -V. This has a few noticeable pitfalls:

• 1.2 goes before 1.2.5;
• v1.2 goes before 1.2.
