#!/bin/bash
#
# bash completion file for core hyper commands
#
# This script provides completion of:
#  - commands and their options
#  - container ids and names
#  - image repos and tags
#  - filepaths
# To enable the completions:
# - place this file in /etc/bash_completion.d
#
# Configuration:
#
# For several commands, the amount of completions can be configured by
# setting environment variables.
#
# You can tailor completion for the "events", "history", "inspect", "run",
# "rmi" and "save" commands by settings the following environment
# variables:
#
# HYPER_COMPLETION_SHOW_IMAGE_IDS
#   "none" - Show names only (default)
#   "non-intermediate" - Show names and ids, but omit intermediate image IDs
#   "all" - Show names and ids, including intermediate image IDs
#
# HYPER_COMPLETION_SHOW_TAGS
#   "yes" - include tags in completion options (default)
#   "no"  - don't include tags in completion options
