Renaming a Formula

Sometimes software and formulae need to be renamed. To rename a formula you need to:

  1. Rename the formula file and its class to a new formula. The new name must meet all the usual rules of formula naming. Fix any test failures that may occur due to the stricter requirements for new formulae than existing formulae (i.e. brew audit --strict must pass for that formula).

  2. Create a pull request to the corresponding tap deleting the old formula file, adding the new formula file, and adding it to formula_renames.json with a commit message like newack: renamed from ack. Use the canonical name (e.g. ack instead of user/repo/ack).

A formula_renames.json example for a formula rename:

  "ack": "newack"
