Ruby plugin for asdf version manager

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

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 following env vars:

• RUBY_CONFIGURE_OPTIONS - use only your configure options
• RUBY_EXTRA_CONFIGURE_OPTIONS - append these configure options along with ones that this plugin already uses

asdf uses the .tool-versions for auto-switching between software versions. To ease migration, you can you 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

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:

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

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

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