An action that wraps brew bump-formula-pr to ease the process of updating the formula on new project releases.

Runs on ubuntu and macos.

It it is recommended to run this Action on macos if bumping a formula in core tap. You can run into issues when doing so on ubuntu.

One should use the Personal Access Token for token input to this Action, not the default GITHUB_TOKEN, because brew bump-formula-pr creates a fork of the formula's tap repository (if needed) and then creates a pull request.

There are two ways to use this Action.

Use if you want to simply bump the formula, when a new release happens.

Listen for new tags in workflow:

on:
  push:
    tags:
      - '*'

The Action will extract all needed informations by itself, you just need to specify the following step in your workflow:

- name: Update Homebrew formula
  uses: dawidd6/action-homebrew-bump-formula@v3
  with:
    # Required, custom GitHub access token with only the 'public_repo' scope 
    token: ${{secrets.TOKEN}}
    # Optional, defaults to homebrew/core
    tap: USER/REPO
    # Formula name, required
    formula: FORMULA
    # Optional, will be determined automatically
    tag: ${{github.ref}}
    # Optional, will be determined automatically
    revision: ${{github.sha}}
    # Optional, if don't want to check for already open PRs
    force: false # true

If livecheck input is set to true, the Action will run brew livecheck to check if any provided formulae are outdated or if tap contains any outdated formulae and then will run brew bump-formula-pr on each of those formulae with proper arguments to bump them.

Might be a good idea to run this on schedule in your tap repo, so one gets automated PRs updating outdated formulae.

If there are no outdated formulae, the Action will just exit.

- name: Update Homebrew formula
  uses: dawidd6/action-homebrew-bump-formula@v3
  with:
    # Required, custom GitHub access token with only the 'public_repo' scope enabled
    token: ${{secrets.TOKEN}}
    # Bump all outdated formulae in this tap
    tap: USER/REPO
    # Bump only these formulae if outdated
    formula: FORMULA-1, FORMULA-2, FORMULA-3, ...
    # Optional, if don't want to check for already open PRs
    force: false # true
    # Need to set this input if want to use `brew livecheck`
    livecheck: true

If only tap input is provided, all formulae in given tap will be checked and bumped if needed.
