# ROX-0install eclass Version 1
# Created by Jim Ramsay (lack@gentoo.org) to ease installation of ROX desktop
# applications and integrate this with zeroinstall-injector
# (http://0install.net)
# These variables are only used inside functions, and so may be set anywhere in
# the ebuild:
#
# ZEROINSTALL_STRIP_REQUIRES - this flag, if set, will force the local
# zeroinstall feed to have all its 'requires' directives stripped out
# LOCAL_FEED_SRC - The ebuild-supplied native feed, for those packages which do
# not already contain one. By default we check for ${APPNAME}.xml and
# ${APPNAME}/${APPNAME}.xml
# This is an extension of rox.eclass
inherit rox
DEPEND="${DEPEND}
>=rox-base/zeroinstall-injector-0.31"
# Some locations for ZEROINSTALL
NATIVE_FEED_DIR="/usr/share/0install.net/native_feeds"
ICON_CACHE_DIR="/var/cache/0install.net/interface_icons"
# Does all the 0install local feed magic you could want:
# - Parses the input file to get the interface URI
# - Edits the input file and installs it to the final location
# - Installs a local feed pointer
#
# Environment variables:
# ZEROINSTALL_STRIP_REQUIRES - If set, strips all 'requires' sections from the XML
# on editing. Default: Not set
#
# 0install_native_feed <src> <destpath>
# src - The XML file we will edit, install, and point at
# path - The path where the implementation will be installed
# IE, the final edited xml will be at <path>/<basename of src>
