# This module contains the helper functions to use in the %post and %preun
# scriptlets of the VO support RPMs. In fact, the following should
# suffice in the SPEC file (replace %{myvo} with the real VO name):

# %post
# if [ $1 -ge 1 ]; then
#    if [ -e /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh ]; then
#       . /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh
#       configure_vo %{myvo}
#    fi
# fi
# 
# %preun
# if [ $1 -eq 0 ]; then
#    if [ -e /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh ]; then
#       . /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh
#       deconfigure_vo %{myvo}
#    fi
# fi

# The base path of this script is where we find the other utilities of
# interest
scriptdir=`dirname $0`

# function configure_vo() takes care of configuring the system by
# running each support module for the VOs given as arguments.
configure_vo() {
    vo-support configure-vo "$@"
}

# function deconfigure_vo() takes care of removing support for the VOs
# passed as arguments.
deconfigure_vo() {
    vo-support deconfigure-vo "$@"
}

# function add_module() runs a module for all configured VOs. Use this
# in the %post script for a module package like so:
# %post
# if [ $1 -ge 1 ]; then
#    if [ -e /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh ]; then
#       . /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh
#       add_module MYMODULE
#    fi
# fi
# 
# The argument is the name of the module to add.
add_module() {
    vo-support add-module $1
}

# function remove_module() runs a module for all VOs. Use
# in the %preun scriptlet in the spec file of a module package:
# %preun
# if [ $1 -eq 0 ]; then
#    if [ -e /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh ]; then
#       . /usr/share/vo-support/scriptlets/maintainerscript-helpers.sh
#       remove_module MYMODULE
#    fi
# fi
# The argument is the name of the module to remove.
remove_module() {
    vo-support remove-module $1
}
