asdf-ruby

Ruby plugin for asdf version manager

Install

asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git

Use

Check asdf readme for instructions on how to install & manage versions of Ruby.

When installing Ruby using asdf install, you can pass custom configure options with the env vars supported by ruby-build.

You may also apply custom patches before building with RUBY_APPLY_PATCHES, e.g.

RUBY_APPLY_PATCHES=$'dir/1.patch\n2.patch\nhttp://example.com/3.patch' asdf install ruby 2.4.1
RUBY_APPLY_PATCHES=$(curl -s https://raw.githubusercontent.com/rvm/rvm/master/patchsets/ruby/2.1.1/railsexpress) asdf install ruby 2.1.1

Default gems

asdf-ruby can automatically install a set of default gems right after installing a Ruby version. To enable this feature, provide a $HOME/.default-gems file that lists one gem per line, for example:

bundler
pry
gem-ctags

Migrating from another Ruby version manager

`.ruby-version` file

asdf uses the .tool-versions for auto-switching between software versions. To ease migration, you can have it read an existing .ruby-version file to find out what version of Ruby should be used. To do this, add the following to $HOME/.asdfrc:

legacy_version_file = yes

Rubies

asdf installs Rubies to $HOME/.asdf/installs/ruby, the directory structure is the same as other version managers, so you can just move the Rubies to this directory:

RVM

mkdir ~/.asdf/installs/
mv ~/.rvm/rubies ~/.asdf/installs/ruby/

rbenv

mkdir ~/.asdf/installs/
mv ~/.rbenv/versions/* ~/.asdf/installs/ruby/

chruby

mkdir ~/.asdf/installs/
mv ~/.rubies ~/.asdf/installs/ruby/
