# @BLURB: An Interface for installing contributed bash-completion scripts
# @DESCRIPTION:
# Simple eclass that provides an interface for installing
# contributed (ie not included in bash-completion proper)
# bash-completion scripts.
# @ECLASS-VARIABLE: BASHCOMPLETION_NAME
# @DESCRIPTION:
# Install the completion script with this name (see also dobashcompletion)
EXPORT_FUNCTIONS pkg_postinst
IUSE="bash-completion"
# Allow eclass to be inherited by eselect without a circular dependency
if [[ ${CATEGORY}/${PN} != app-admin/eselect ]]; then
RDEPEND="bash-completion? ( app-admin/eselect )"
fi
PDEPEND="bash-completion? ( app-shells/bash-completion )"
# @FUNCTION: dobashcompletion
# @USAGE: < file > [ new_file ]
# @DESCRIPTION:
# First arg, <file>, is required and is the location of the bash-completion
# script to install. If the variable BASHCOMPLETION_NAME is set in the
# ebuild, dobashcompletion will install <file> as
# /usr/share/bash-completion/$BASHCOMPLETION_NAME. If it is not set,
# dobashcompletion will check if a second arg [new_file] was passed, installing as
# the specified name. Failing both these checks, dobashcompletion will
# install the file as /usr/share/bash-completion/${PN}.

# @FUNCTION: bash-completion_pkg_postinst
