45# @ECLASS-VARIABLE: RUBY_OPTIONAL 47# @ECLASS-VARIABLE: RUBY_OPTIONAL
46# @DESCRIPTION: 48# @DESCRIPTION:
47# Set the value to "yes" to make the dependency on a Ruby interpreter optional. 49# Set the value to "yes" to make the dependency on a Ruby interpreter
50# optional and then ruby_implementations_depend() to help populate
51# DEPEND and RDEPEND.
52
53# @ECLASS-VARIABLE: RUBY_S
54# @DEFAULT_UNSET
55# @DESCRIPTION:
56# If defined this variable determines the source directory name after
57# unpacking. This defaults to the name of the package. Note that this
58# variable supports a wildcard mechanism to help with github tarballs
59# that contain the commit hash as part of the directory name.
60
61# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
62# @DEFAULT_UNSET
63# @DESCRIPTION:
64# If defined this variable contains a whitelist of shared objects that
65# are allowed to exist even if they don't link to libruby. This avoids
66# the QA check that makes this mandatory. This is most likely not what
67# you are looking for if you get the related "Missing links" QA warning,
68# since the proper fix is almost always to make sure the shared object
69# is linked against libruby. There are cases were this is not the case
70# and the shared object is generic code to be used in some other way
71# (e.g. selenium's firefox driver extension). When set this argument is
72# passed to "grep -E" to remove reporting of these shared objects.
