# @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.
|
||
|
#
|
||
|
# Please note that for the time being this eclass does NOT support luajit.
|
||
|
#
|
||
|
# @EXAMPLE:
|
||
|
# @CODE
|
||
|
# EAPI=7
|
||
|
#
|
||
|
# LUA_COMPAT=( lua5-{1..3} )
|
||
|
#
|

|
# inherit lua

#

# [...]

# @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:
|
||
|

|
# ${WORKDIR}/foo-1.3-lua5-1
|

|
# @CODE
|
||
|
|

|
# @ECLASS-VARIABLE: ELUA

|

# @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
