# @BLURB: An eclass for installing Ruby packages with proper support for multiple Ruby slots.
# @DESCRIPTION:
# The Ruby eclass is designed to allow an easier installation of Ruby packages
# and their incorporation into the Gentoo Linux system.
#
# Currently available targets are listed in ruby-utils.eclass
#
# This eclass does not define the implementation of the configure,
# compile, test, or install phases. Instead, the default phases are
# used. Specific implementations of these phases can be provided in
# the ebuild either to be run for each Ruby implementation, or for all
# Ruby implementations, as follows:
#
# * each_ruby_configure
# * all_ruby_configure
# @ECLASS-VARIABLE: USE_RUBY
# @DEFAULT_UNSET
# @REQUIRED
# @DESCRIPTION:
# This variable contains a space separated list of targets (see above) a package
# is compatible to. It must be set before the `inherit' call. There is no
# default. All ebuilds are expected to set this variable.
# @ECLASS-VARIABLE: RUBY_PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# A String or Array of filenames of patches to apply to all implementations.
# @ECLASS-VARIABLE: RUBY_OPTIONAL
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set the value to "yes" to make the dependency on a Ruby interpreter
# optional and then ruby_implementations_depend() to help populate
# DEPEND and RDEPEND.
# @ECLASS-VARIABLE: RUBY_S
# @DEFAULT_UNSET
# @DESCRIPTION:
# If defined this variable determines the source directory name after
# unpacking. This defaults to the name of the package. Note that this
# variable supports a wildcard mechanism to help with github tarballs
# that contain the commit hash as part of the directory name.
# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
# @DEFAULT_UNSET
# @DESCRIPTION:
# If defined this variable contains a whitelist of shared objects that
# are allowed to exist even if they don't link to libruby. This avoids
# the QA check that makes this mandatory. This is most likely not what
# you are looking for if you get the related "Missing links" QA warning,
# since the proper fix is almost always to make sure the shared object
# is linked against libruby. There are cases were this is not the case
# and the shared object is generic code to be used in some other way
# (e.g. selenium's firefox driver extension). When set this argument is
# passed to "grep -E" to remove reporting of these shared objects.
