Run various versions of ruby command

all-ruby

This software is a script to install historic Ruby versions since ruby-0.49. Also, all-ruby script runs all ruby binaries with same arguments.

Platform

This software is developed on Debian GNU/Linux 10 (buster) amd64.

However Ruby doesn't support 64 bit platform until ruby 1.8.0. So, the older ruby needs 32 bit development tools which can be installed as follows.

% sudo dpkg --add-architecture i386
% sudo apt update
% sudo apt-get build-dep ruby2.5
% sudo apt install rake gcc-multilib \
    zlib1g:i386 libncurses5:i386 libgdbm6:i386 libssl1.1:i386 \
    libreadline7:i386 libffi6:i386

For Debian GNU/Linux 9 (stretch) :

% sudo apt-get build-dep ruby2.3
% sudo apt install rake gcc-multilib \
    zlib1g:i386 libncurses5:i386 libgdbm3:i386 libssl1.0.2:i386 \
    libreadline7:i386 libffi6:i386

Usage

This software provides Rakefile and "rake all" downloads and builds historic ruby versions.

% git clone https://github.com/akr/all-ruby.git
% cd all-ruby
% rake setup_build
% rake all  # this takes long time

Note that rake setup_build is same as mkdir ../build-all-ruby; ln -s ../build-all-ruby build. build-all-ruby directory is required to avoid that ruby -v emits last_commit= line.

all-ruby script runs all ruby binaries.

% ./all-ruby -e 'p RUBY_VERSION'
ruby-0.49             -e:1: syntax error
	      exit 1
ruby-0.50             -e:1: syntax error
	      exit 1
ruby-0.51             -e:1: undefined method `p' for "main"(Object)
	      exit 1

	      exit 1

	      exit 1
...

	      exit 1

...
ruby-2.7.0-preview1   Integer

Documentation

rake without arguments shows the help message for the Rakefile.

% rake
"rake all" will install 338 ruby
"rake list" shows versions
"rake sync" updates versions

all-ruby without arguments shows help message for all-ruby script.

% ./all-ruby
usage: all-ruby RUBY-ARGS
environment variables:
  ALL_RUBY_SINCE=ruby-1.4               run only versions since specified one
  ALL_RUBY_BINS='ruby-2.4.4 ruby-2.5.1' run only versions specfied
  ALL_RUBY_ADDBINS=./ruby               run specified commands additionaly
  ALL_RUBY_SHOW_DUP=yes                 don't suppress duplicated output

Docker

Dockerfile is provided to generate a docker image containing ruby binaries built by the Rakefile.

Pre-built docker image can be used as follows:

% docker pull rubylang/all-ruby
% docker run --rm rubylang/all-ruby ./all-ruby -v
% docker run --rm -e 'ALL_RUBY_SINCE=ruby-2.0' \
    -e 'ALL_RUBY_ADDBINS=/usr/bin/ruby' \
    rubylang/all-ruby ./all-ruby -e 'p 0.class'

If you want to build a docker image yourself, you can use following command. This uses your CPUs parallel.

% docker build ./ -t my-all-ruby

If you want to use only n CPUs, build argument j=n can be used. (--cpuset-cpus option of "docker build" is also usable.)

% docker build ./ --build-arg j=1 -t my-all-ruby
