# Bash completion script for brew(1)
#
# To use, edit your .bashrc and add:
# source `brew --prefix`/Library/Contributions/brew_bash_completion.sh
#
# The __brew_ps1() function can be used to annotate your PS1 with
# Homebrew debugging information; it behaves similarly to the __git_ps1()
# function provided by the git's bash completion script.
#
# For example, the prompt string
# PS1='\u@\h \W $(__brew_ps1 "(%s)") $'
#
# would result in a prompt like
# user@hostname cwd $
#
# but if you are currently engaged in an interactive or debug install,
# (i.e., you invoked `brew install` with either '-i' or '-d'), then the
# prompt would look like
# user@hostname cwd (formula_name|DEBUG) $
#
# You can customize the output string, e.g. $(__brew_ps1 "[%s]") would
# output "[formula_name|DEBUG]". The default (if you do not provide a
# format argument) is to print "(formula_name|DEBUG)" prefixed with a
# single space.
