Homebrew Portable Ruby

Formulae and tools to build versions of Ruby that can be installed and run from anywhere on the filesystem.

How do I install these formulae

Just brew install homebrew/portable-ruby/<formula>.

How do I build packages for these formulae

macOS

Run brew portable-package ruby inside an OS X 10.9 VM (so it is compatible with all working Homebrew macOS versions).

Linux

Build a Docker image for your architecture by running one of the following commands.

• docker build -f Dockerfile --platform linux/amd64 --build-arg img=debian/eol:wheezy -t homebrew-portable .
• docker build -f Dockerfile --platform linux/arm/v6 --build-arg img=resin/rpi-raspbian:wheezy -t homebrew-portable .
• docker build -f Dockerfile --platform linux/arm64/v8 --build-arg img=debian/eol:jessie -t homebrew-portable .

Build the portable-ruby package using that Docker image.

docker run --name=homebrew-portable-ruby -w /bottle homebrew-portable brew portable-package ruby
docker cp homebrew-portable-ruby:/bottle .

Current Status

Used in production for Homebrew/brew.

Linux

1. irb on Linux builds seems to fail to link to ncurses statically. If portable-ncurses is removed, irb will fail to handle left, right or backspace keystroke.
