# 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
#
# V0.5.0
#
# 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.
# Tell shellcheck what kind of file this is.
# shellcheck shell=bash
# Make sure this is bash that's running and return otherwise.
# Use POSIX syntax for this line:
if [ -z "${BASH_VERSION-}" ]; then
return 1;
fi
# We only support Bash 3.1+.
# Note: BASH_VERSINFO is first available in Bash-2.0.
