 # @SUPPORTED_EAPIS: 7
 # @BLURB: An eclass for Lua packages not installed for multiple implementations.
 # @DESCRIPTION:
 # An extension of lua.eclass suite for packages which don't support being
 # installed for multiple Lua implementations. This mostly includes software
 # embedding Lua.
 #
 # This eclass sets correct IUSE.  It also provides LUA_DEPS
 # and LUA_REQUIRED_USE that need to be added to appropriate ebuild
 # metadata variables.
 #
 # The eclass exports LUA_SINGLE_USEDEP that is suitable for depending
 # on other packages using the eclass.  Dependencies on packages using
 # lua.eclass should be created via lua_gen_cond_dep() function, using
 # LUA_USEDEP placeholder.
 #
 # Please note that packages support multiple Lua implementations
 # (using lua.eclass) cannot depend on packages not supporting
 # them (using this eclass).
 #
 # Note that since this eclass always inherits lua-utils as well, in ebuilds
 # using the former there is no need to explicitly inherit the latter in order
 # to use helper functions such as lua_get_CFLAGS.
 #
 # @EXAMPLE:
 # @CODE
 # EAPI=7
 #
 # LUA_COMPAT=( lua5-{1..3} )
 #
 # inherit lua-single
 #
 # [...]
 #
 # REQUIRED_USE="${LUA_REQUIRED_USE}"
 # DEPEND="${LUA_DEPS}"
 # RDEPEND="${DEPEND}
 #     $(lua_gen_cond_dep '
 #         dev-lua/foo[${LUA_USEDEP}]
 #     ')
 # "
 # BDEPEND="virtual/pkgconfig"
 #
 # # Only neeed if the setup phase has to do more than just call lua-single_pkg_setup
 # pkg_setup() {
 #     lua-single_pkg_setup
 #     [...]
 # }
 #
 # src_install() {
 #     emake LUA_VERSION="$(lua_get_version)" install
 # }

 EXPORT_FUNCTIONS pkg_setup
 # @ECLASS-VARIABLE: LUA_COMPAT
 # @REQUIRED
 # @PRE_INHERIT
 # @DESCRIPTION:
 # This variable contains a list of Lua implementations the package
 # supports. It must be set before the `inherit' call. It has to be
 # an array.
 #
 # Example:
 # @CODE
 # LUA_COMPAT=( lua5-1 lua5-2 lua5-3 )
 # @CODE
 #
 # Please note that you can also use bash brace expansion if you like:
 # @CODE
 # LUA_COMPAT=( lua5-{1..3} )
 # @CODE
 # @ECLASS-VARIABLE: LUA_COMPAT_OVERRIDE
 # @USER_VARIABLE
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # This variable can be used when working with ebuilds to override
 # the in-ebuild LUA_COMPAT. It is a string listing all
 # the implementations which package will be built for. It need be
 # specified in the calling environment, and not in ebuilds.
 #
 # It should be noted that in order to preserve metadata immutability,
 # LUA_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
 # The state of LUA_TARGETS is ignored, and all the implementations
 # in LUA_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
 # manually.
 #
 # Example:
 # @CODE
 # LUA_COMPAT_OVERRIDE='lua5-2' emerge -1v dev-lua/foo
 # @CODE
 # @ECLASS-VARIABLE: LUA_REQ_USE
 # @DEFAULT_UNSET
 # @PRE_INHERIT
 # @DESCRIPTION:
 # The list of USE flags required to be enabled on the chosen Lua
 # implementations, formed as a USE-dependency string. It should be valid
 # for all implementations in LUA_COMPAT, so it may be necessary to
 # use USE defaults.
 # This must be set before calling `inherit'.
 #
 # Example:
 # @CODE
 # LUA_REQ_USE="deprecated"
 # @CODE
 #
 # It will cause the Lua dependencies to look like:
 # @CODE
 # lua_targets_luaX-Y? ( dev-lang/lua:X.Y[deprecated] )
 # @CODE
 # @ECLASS-VARIABLE: LUA_DEPS
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated Lua dependency string for all
 # implementations listed in LUA_COMPAT.
 #
 # Example use:
 # @CODE
 # RDEPEND="${LUA_DEPS}
 #     dev-foo/mydep"
 # DEPEND="${RDEPEND}"
 # @CODE
 #
 # Example value:
 # @CODE
 # lua_targets_lua5-1? ( dev-lang/lua:5.1 )
 # lua_targets_lua5-2? ( dev-lang/lua:5.2 )
 # @CODE
 # @ECLASS-VARIABLE: LUA_REQUIRED_USE
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated required-use expression which ensures at
 # least one Lua implementation has been enabled.
 #
 # This expression should be utilized in an ebuild by including it in
 # REQUIRED_USE, optionally behind a use flag.
 #
 # Example use:
 # @CODE
 # REQUIRED_USE="lua? ( ${LUA_REQUIRED_USE} )"
 # @CODE
 #
 # Example value:
 # @CODE
 # || ( lua_targets_lua5-1 lua_targets_lua5-2 )
 # @CODE
 # @ECLASS-VARIABLE: LUA_SINGLE_USEDEP
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated USE-dependency string which can be used
 # to depend on another lua-single package being built for the same
 # Lua implementations.
 #
 # If you need to depend on a multi-impl (lua.eclass) package, use
 # lua_gen_cond_dep with LUA_USEDEP placeholder instead.
 #
 # Example use:
 # @CODE
 # RDEPEND="dev-lua/foo[${LUA_SINGLE_USEDEP}]"
 # @CODE
 #
 # Example value:
 # @CODE
 # lua_single_target_lua5-1(-)?
 # @CODE
 # @ECLASS-VARIABLE: LUA_USEDEP
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated USE-dependency string which can be used to
 # depend on another Lua package being built for the same Lua
 # implementations.
 #
 # Example use:
 # @CODE
 # RDEPEND="dev-lua/foo[${LUA_USEDEP}]"

 # @BLURB: A common eclass for Lua packages
 # @DESCRIPTION:
 # A common eclass providing helper functions to build and install
 # packages supporting being installed for multiple Lua implementations.
 #
 # This eclass sets correct IUSE. Modification of REQUIRED_USE has to
 # be done by the author of the ebuild (but LUA_REQUIRED_USE is
 # provided for convenience, see below). The eclass exports LUA_DEPS
 # and LUA_USEDEP so you can create correct dependencies for your
 # package easily. It also provides methods to easily run a command for
 # each enabled Lua implementation and duplicate the sources for them.
 #
 # Note that since this eclass always inherits lua-utils as well, in ebuilds
 # using the former there is no need to explicitly inherit the latter in order
 # to use helper functions such as lua_get_CFLAGS.
 #
 # @EXAMPLE:
 # @CODE
 # EAPI=7
 #
 # LUA_COMPAT=( lua5-{1..3} )
 #
 # inherit lua
 #
 # [...]
 #
 # REQUIRED_USE="${LUA_REQUIRED_USE}"
 # DEPEND="${LUA_DEPS}"
 # RDEPEND="${DEPEND}
 #     dev-lua/foo[${LUA_USEDEP}]"
 # BDEPEND="virtual/pkgconfig"
 #
 # lua_src_install() {
 #     emake LUA_VERSION="$(lua_get_version)" install

 # @ECLASS-VARIABLE: LUA_COMPAT
 # @REQUIRED
 # @PRE_INHERIT
 # @DESCRIPTION:
 # This variable contains a list of Lua implementations the package
 # supports. It must be set before the `inherit' call. It has to be
 # an array.
 #
 # Example:
 # @CODE
 # LUA_COMPAT=( lua5-1 lua5-2 lua5-3 )
 # @CODE
 #
 # Please note that you can also use bash brace expansion if you like:
 # @CODE
 # LUA_COMPAT=( lua5-{1..3} )
 # @CODE
 # @ECLASS-VARIABLE: LUA_COMPAT_OVERRIDE
 # @USER_VARIABLE
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # This variable can be used when working with ebuilds to override
 # the in-ebuild LUA_COMPAT. It is a string listing all
 # the implementations which package will be built for. It need be
 # specified in the calling environment, and not in ebuilds.
 #
 # It should be noted that in order to preserve metadata immutability,
 # LUA_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
 # The state of LUA_TARGETS is ignored, and all the implementations
 # in LUA_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
 # manually.
 #
 # Example:
 # @CODE
 # LUA_COMPAT_OVERRIDE='lua5-2' emerge -1v dev-lua/foo
 # @CODE
 # @ECLASS-VARIABLE: LUA_REQ_USE
 # @DEFAULT_UNSET
 # @PRE_INHERIT
 # @DESCRIPTION:
 # The list of USE flags required to be enabled on the chosen Lua
 # implementations, formed as a USE-dependency string. It should be valid
 # for all implementations in LUA_COMPAT, so it may be necessary to
 # use USE defaults.
 # This must be set before calling `inherit'.
 #
 # Example:
 # @CODE
 # LUA_REQ_USE="deprecated"
 # @CODE
 #
 # It will cause the Lua dependencies to look like:
 # @CODE
 # lua_targets_luaX-Y? ( dev-lang/lua:X.Y[deprecated] )
 # @CODE
 # @ECLASS-VARIABLE: BUILD_DIR
 # @OUTPUT_VARIABLE
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # The current build directory. In global scope, it is supposed to
 # contain an initial build directory; if unset, it defaults to ${S}.
 #
 # In functions run by lua_foreach_impl(), the BUILD_DIR is locally
 # set to an implementation-specific build directory. That path is
 # created through appending a hyphen and the implementation name
 # to the final component of the initial BUILD_DIR.
 #
 # Example value:
 # @CODE
 # ${WORKDIR}/foo-1.3-lua5-1
 # @CODE
 # @ECLASS-VARIABLE: LUA_DEPS
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated Lua dependency string for all
 # implementations listed in LUA_COMPAT.
 #
 # Example use:
 # @CODE
 # RDEPEND="${LUA_DEPS}
 #   dev-foo/mydep"
 # DEPEND="${RDEPEND}"
 # @CODE
 #
 # Example value:
 # @CODE
 # lua_targets_lua5-1? ( dev-lang/lua:5.1 )
 # lua_targets_lua5-2? ( dev-lang/lua:5.2 )
 # @CODE
 # @ECLASS-VARIABLE: LUA_REQUIRED_USE
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated required-use expression which ensures at
 # least one Lua implementation has been enabled.
 #
 # This expression should be utilized in an ebuild by including it in
 # REQUIRED_USE, optionally behind a use flag.
 #
 # Example use:
 # @CODE
 # REQUIRED_USE="lua? ( ${LUA_REQUIRED_USE} )"
 # @CODE
 #
 # Example value:
 # @CODE
 # || ( lua_targets_lua5-1 lua_targets_lua5-2 )
 # @CODE
 # @ECLASS-VARIABLE: LUA_USEDEP
 # @OUTPUT_VARIABLE
 # @DESCRIPTION:
 # This is an eclass-generated USE-dependency string which can be used to
 # depend on another Lua package being built for the same Lua
 # implementations.
 #
 # Example use:
 # @CODE
 # RDEPEND="dev-lua/foo[${LUA_USEDEP}]"
 # @CODE
 #
 # Example value:
 # @CODE
