Homebrew: programmatically replicate an installation?

Question

I would like to copy my macos brew configuration to multiple machines.

Is there a way to programmatically check the status of brew or create a set of commands for it to synchronize the state with another machine?

update: there seems to be nothing, so I put together a quick package that does this. This has worked well for me so far.

Here is a simple package that runs brew on multiple machines, synchronizing them so that they have the same installed packages. I also add support for font synchronization.

      [ $verbose -gt 0 ] && echo Processing package: $pkg
      # Find options used for this package
      options=$(brew info --json=v1 $pkg | jq '.[].installed[0].used_options')
      echo "{\"name\":\"$pkg\",\"used_options\":$options}"                >> "$f"

It's probably not quite what you are looking for in terms of synchronizing installations, but you should check out Brewfiles and Bundler: https://github.com/Homebrew/homebrew-bundle
