Bubble bubble, toil and brew...

Alchemist Backup

Alchemist can backup your entire Homebrew (macOS and Linux) or Chocolatey (Windows) instance. It does this by retrieving the list of installed packages and creating a script that can be run to restore your entire Homebrew or Chocolatey instance.

alchemist --backup

If you run into troubles backing up your Homebrew instance, it's recommended to try running Alcehmist with the --update flag first.

Alchemist Update

macOS and Linux

Alchemist automates the entire Homebrew update process including:

1. Updating available taps and formula references
2. Upgrading packages
3. Upgrading casks
4. Cleaning up old/stale taps and formula
5. Checking for problems with your Homebrew instance

Windows

Alchemist will update all of your Chocolatey packages:

alchemist --update

Install

macOS and Linux

# Setup the tap
brew tap justintime50/formulas

# Install the tool
brew install alchemist

Windows

Download the Windows binary from the releases page.
