Ruby + MMTk

This repository provides builds of the Ruby programming language, with MMTk as a garbage collector. To download a build, find a recent nightly release at https://github.com/Shopify/ruby-mmtk-builder/releases/tag/nightly and download either the debug or release artefact.

Use ruby --mmtk to enable. See ruby --help for more information.

Use as a development environment

./build.sh will set up a working full-source checkout and build of Ruby with MMTk. MMTk is Linux only.

A Containerfile is included that will run build.sh and create an image with the resulting Ruby build.

Make sure you have installed podman and then run

podman build .

Within this directory.

The following environment variables can be used

WITH_LATEST_MMTK_CORE=1 to use latest MMTk (may not work.)

WITH_UPSTREAM_RUBY=1 to merge with upstream Ruby (may not work.)

WITH_DEBUG=1 to build a debug version.

First build using ./build.sh. Then TAG=mytag ./package.sh to build a tarball.
