Specifically, the package # should be a Desklet or Control ONLY (and *not* a Sensor). You # technically could have an ebuild that works around this limitation, # but no new packages should be added to the tree that do this (mainly # for ease of maintenance). # @ECLASS-VARIABLE: DESKLET_NAME # @DESCRIPTION: # *Optional* The name of the Desklet, if the package is one. The # default is to assume a Desklet with the name being ${PN} without the # "desklet-" prefix. # @ECLASS-VARIABLE: CONTROL_NAME # @DESCRIPTION: # *Optional* The name of the Control, if the package is one. # @ECLASS-VARIABLE: DOCS # @DESCRIPTION: # Anything (like a README) that should be dodoc'd. # @ECLASS-VARIABLE: SLOT # @DESCRIPTION: # Set only if the package is a Control and it provides a different # interface (i.e. expands to a different install directory) than a # previous version. inherit eutils multilib python if [[ -n "${CONTROL_NAME}" ]]; then debug-print "Looking for a Control named \"${CONTROL_NAME}\"" MY_PN="${CONTROL_NAME}" SRC_URI="http://gdesklets.de/files/controls/${MY_PN}/${MY_PN}-${PV}.tar.gz" unset DESKLET_NAME else # [[ -n "${DESKLET_NAME}" ]]; then # Assume an unset DESKLET_NAME means the name is ${PN} without # the "desklet-" prefix [[ -z "${DESKLET_NAME}" ]] && DESKLET_NAME="${PN#desklet-}" debug-print "Looking for a Desklet named \"${DESKLET_NAME}\"" MY_PN="${DESKLET_NAME}" SRC_URI="http://gdesklets.de/files/desklets/${MY_PN}/${MY_PN}-${PV}.tar.gz" fi MY_P="${MY_PN}-${PV}" S="${WORKDIR}/${MY_PN}" SLOT="0" # Ebuild writer shouldn't need to touch these (except maybe RDEPEND) IUSE="" RDEPEND=">=gnome-extra/gdesklets-core-0.36.1-r3" GDESKLETS_INST_DIR="${ROOT}usr/$(get_libdir)/gdesklets" # @FUNCTION: gdesklets_src_install # @DESCRIPTION: # Installs a Desklet or Control depending on which is set of # CONTROL_NAME or DESKLET_NAME gdesklets_src_install() { debug-print-function $FUNCNAME $* # Disable compilation of included python modules (for Controls) python_disable_pyc # Avoid sandbox violations caused by misbehaving packages (bug #128289) addwrite "${ROOT}/root/.gnome2" # Both Displays and Controls only need to be readable insopts -m0744 debug-print-section docs_install # Install some docs if so requested (and then delete them so they # don't get copied into the installation directory) [[ -n "${DOCS}" ]] && dodoc ${DOCS} && \ rm -f ${DOCS} \ debug-print "Installed and deleted ${DOCS}" # LICENSE doesn't need to get installed if it exists find . -name LICENSE -delete if [[ -n "${DESKLET_NAME}" ]]; then debug-print-section display_install # Base installation directory for displays from this desklet INSDIR="${GDESKLETS_INST_DIR}/Displays/${DESKLET_NAME}" debug-print "Installing into ${INSDIR}" debug-print "Exiting Display-specific installation code" elif [[ -n "${CONTROL_NAME}" ]]; then debug-print-section control_install # Unique name for this Control and its interface CTRL_DIRNAME=$( "${GDESKLETS_INST_DIR}/gdesklets-control-getid" `pwd` 2> /dev/null ) einfo "Installing Control ${CTRL_DIRNAME}" # Base installation directory for this Control INSDIR="${GDESKLETS_INST_DIR}/Controls/${CTRL_DIRNAME}" debug-print "Installing into ${INSDIR}" # Mercilessly delete all existing compiled code find . -iname '*.py[co]' -delete debug-print "Exiting Control-specific installation code" else die "nothing to install, is the ebuild written correctly?" fi debug-print-section common_install # Create the proper subdirectory in the global Controls or # Displays directory dodir "${INSDIR}" insinto "${INSDIR}" doins -r * } # @FUNCTION: gdesklets_pkg_postinst # @DESCRIPTION: # Marks the Control for rebuilding on Python version change and # compiles the Python code or display a useful message to the user, # depending on which of CONTROL_NAME or DESKLET_NAME is set. gdesklets_pkg_postinst() { # The only time compilation of python modules should occur is # for Controls, since Displays are run from inside the sandbox # (and therefore can't be compiled). if [[ -n "${CONTROL_NAME}" ]]; then CTRL_DIRNAME=$( "${GDESKLETS_INST_DIR}/gdesklets-control-getid" `pwd` 2> /dev/null ) python_need_rebuild python_mod_optimize "${GDESKLETS_INST_DIR}/Controls/${CTRL_DIRNAME}" else einfo "Each user can now add this desklet to their desktop through the" einfo "gDesklets shell or the command line (.display files can be" einfo "found in ${GDESKLETS_INST_DIR}/Displays/${DESKLET_NAME})." fi } EXPORT_FUNCTIONS src_install pkg_postinst
