Ruby MRI development with Docker and Dip

The repo contains Docker and Dip configuration for developing Ruby MRI.

• Clone Ruby to next to this project's folder:

git clone https://github.com/ruby/ruby.git ../ruby

If you want to keep Ruby source code in the different location, create a dip.override.yml file with following contents:

# dip.override.yml
environment:
  RUBY_SRC_PATH: "relative/path/to/ruby"

• Install Dip

• Provision the dev container and volumes:

dip provision

• Run make tasks with Dip:

dip make

# for example, to run pattern matching tests
dip make test-all TESTS='test/ruby/test_pattern_matching.rb'

• Login into the container:

dip bash

• (Optionally for VS Code users) Run container in the background and connect to it via Remote Containers feature:

dip up -d dev

# go to Remote-Container: Attach to Running Container...
# and chooose ruby_dev_1

Inspired by @kirs post "Contributing to Ruby MRI". The main difference is that the setup from this repo is IDE-agnostic (and at the same time plays well with VS Code Remote Containers).
