I’ve always liked Homebrew’s bundle command. You can save a snapshot of everything you’ve installed with Homebrew, and then reinstall the snapshot on a new system.
I also like Ruby’s Bundler, which lets you save all of the gems needed by an application and then install them easily with bundle install.
However, I don’t like installing Ruby gems with Homebrew, mostly because brew-gem isn’t up-to-date and barely functions these days. I install all of my gems with just gem install.
Because of this, binaries that are installed by gems aren’t included when I do a brew bundle install. And Ruby’s bundler is project-specific. So I wrote a script that will save a snapshot of every gem that has a binary installed on your system, and then do a gem install on all of them when setting up a new system.
I gave it a decent README, so if this is of interest, go check it out. If you use any of my tools like howzit or na, you’ve probably installed those with gem install and they won’t be included if you try to restore using Homebrew (or dot files, etc.). So do yourself a favor and create a snapshot!
Please share issues and suggestions using the Issues section of the script’s GitHub home.
