# promlib

Prometheus Library (a.k.a. promlib) is the foundation of the Grafana Prometheus data source backend.

### How to tag/version?

- Checkout the commit you want to tag (`git checkout <COMMIT_SHA>`)
- Run `git tag pkg/promlib/<VERSION>` (For example `git tag pkg/promlib/v0.0.12`)
  - NOTE: We're using Lightweight Tags, so no other options are required
- Run `git push origin pkg/promlib/<VERSION>`
- Verify that the tag was created successfully [here](https://github.com/grafana/grafana/tags)
- DO NOT RELEASE anything! Tagging is enough.
- After tagging and waiting 5-10 minutes for go module registry to catch up just bump the `promlib` version on `grafana/grafana`
  - Bumping the version on `grafana/grafana` is not necessary as `grafana/grafana` is using the local version of it always.
  - **But it is a good practice to do it.**
