# bash-preexec.sh -- Bash support for ZSH-like 'preexec' and 'precmd' functions.
# https://github.com/rcaloras/bash-preexec
#
#
# 'preexec' functions are executed before each interactive command is
# executed, with the interactive command as its argument. The 'precmd'
# function is executed before each prompt is displayed.
#
# Author: Ryan Caloras (ryan@bashhub.com)
# Forked from Original Author: Glyph Lefkowitz
#
# V0.4.1
#

# General Usage:
#
#  1. Source this file at the end of your bash profile so as not to interfere
#     with anything else that's using PROMPT_COMMAND.
#
#  2. Add any precmd or preexec functions by appending them to their arrays:
#       e.g.
#       precmd_functions+=(my_precmd_function)
#       precmd_functions+=(some_other_precmd_function)
#
#       preexec_functions+=(my_preexec_function)
#
#  3. Consider changing anything using the DEBUG trap or PROMPT_COMMAND
#     to use preexec and precmd instead. Preexisting usages will be
#     preserved, but doing so manually may be less surprising.
#
#  Note: This module requires two Bash features which you must not otherwise be
#  using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. If you override
#  either of these after bash-preexec has been installed it will most likely break.

# Make sure this is bash that's running and return otherwise.

    # set PS1 from a PROMPT_COMMAND that runs just before us. Setting ITERM_ORIG_PS1
    # at the top of the script will overwrite liquidprompt's PS1, whose value would
    # never make it into ITERM_ORIG_PS1. Issue 4532. It's important to check
