# @BLURB: An eclass for supporting ruby scripts and bindings in non-ruby packages
# @DESCRIPTION:
# The ruby-utils eclass is designed to allow an easier installation of
# Ruby scripts and bindings for non-ruby packages.
#
# This eclass does not set any metadata variables nor export any phase
# functions. It can be inherited safely.

# @ECLASS-VARIABLE: RUBY_TARGETS_PREFERENCE
# @DESCRIPTION:
# This variable lists all the known ruby targets in preference of use as
# determined by the ruby team. By using this ordering rather than the
# USE_RUBY mandated ordering we have more control over which ruby
# implementation will be installed first (and thus eselected). This will
# provide for a better first installation experience.
# All RUBY_TARGETS
RUBY_TARGETS_PREFERENCE="ruby20 ruby19 "
# All other active ruby targets
RUBY_TARGETS_PREFERENCE+="ruby21 ruby22 "
