# bash completion file for ostree commands
#
# This script provides completion of:
#  - commands and their options
#  - ostree commit checksums
#  - ostree ref names
#
# To enable the completions either:
#  - place this file in /etc/bash_completion.d
# or
#  - copy this file to e.g. ~/.ostree-completion.sh and add the line
#    below to your .bashrc after bash completion features are loaded
#    . ~/.ostree-completion.sh
#
# Note for developers:
# Please arrange options sorted alphabetically by long name with the short
# options immediately following their corresponding long form.
# This order should be applied to lists, alternatives and code blocks.

# TODO
#
#  - Long form options with an equal sign (--foo=BAR) are not parsed.
#
#  - Structured option arguments (e.g. --foo KEY=VALUE) are not parsed.
#
#  - Static deltas could likely be completed. (e.g. ostree static-delta delete [TAB])
