[gentoo-dev] add built_with_use_die() to eutils.eclass ?

[dju` <dju@gentoo.org>]

[-- Attachment #1: Type: text/plain, Size: 9788 bytes --]

Hello,

I'd like to add the following function to eutils.eclass :

# Generate a standard error message for missing USE flags
# in existing packages, and die.
#
# Usage: built_with_use_die <category/package> <functionality> [<USE flag>]
#    ex: built_with_use_die dev-util/subversion python
#    or: built_with_use_die net-www/apache LDAP ldap
#
# Typical usage:
#   if ! built_with_use dev-util/subversion python ; then
#        built_with_use_die dev-util/subversion python
#   fi
#
# Note: when <USE flag> is not specified, <functionality> is used for the USE 
flag name.
built_with_use_die() {
        local package=$1
        local func=$2
        local use_flag=$3

        [[ -z ${use_flag} ]] && use_flag=${func}

        eerror "Your ${package} package has been built without"
        eerror "${func} support, please enable the '${use_flag}' USE flag and"
        eerror "re-emerge ${package}."
        elog "You can enable this USE flag either globally in /etc/make.conf,"
        elog "or just for specific packages in /etc/portage/package.use."
        die "${package} missing ${func} support"
}

This function is already used in latest www-apps/trac ebuilds. The following 
packages might be concerned, i.e. packages that are currently using 
built_with_use() :
