# 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.

# the end of this script:
# PS1="$(iterm2_prompt_prefix)$PS1($iterm2_prompt_suffix)"
# and have iterm2_prompt_prefix set a global variable that tells precmd not to
# output anything and have iterm2_prompt_suffix reset that variable.
# Unfortunately, command substitutions run in subshells and can't
# communicate to the outside world.
# Instead, we have this workaround. We save the original value of PS1 in
# $ITERM_ORIG_PS1. Then each time this function is run (it's called from
# PROMPT_COMMAND just before the prompt is shown) it will change PS1 to a
# string without any command substitutions by doing eval on ITERM_ORIG_PS1. At
# this point ITERM_PREEXEC_INTERACTIVE_MODE is still the empty string, so preexec
# won't produce output for command substitutions.

# is undefined (not just empty) and initializes it. We can't initialize this at the
# top of the script because it breaks with liquidprompt. liquidprompt wants to
# 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

# There are three possible paths in life.
#
# 1) A command is entered at the prompt and you press return.
# The following steps happen:
# * iterm2_preexec is invoked
# * PS1 is set to ITERM2_PRECMD_PS1
# * ITERM2_SHOULD_DECORATE_PROMPT is set to 1
# * The command executes (possibly reading or modifying PS1)
# * iterm2_precmd is invoked
# * ITERM2_PRECMD_PS1 is set to PS1 (as modified by command execution)
# * PS1 gets our escape sequences added to it
# * zsh displays your prompt
# * You start entering a command
#
# 2) You press ^C while entering a command at the prompt.
# The following steps happen:
# * (iterm2_preexec is NOT invoked)
# * iterm2_precmd is invoked
# * iterm2_before_cmd_executes is called since we detected that iterm2_preexec was not run
# * (ITERM2_PRECMD_PS1 and PS1 are not messed with, since PS1 already has our escape
# sequences and ITERM2_PRECMD_PS1 already has PS1's original value)
# * zsh displays your prompt
# * You start entering a command
#
# 3) A new shell is born.
# * PS1 has some initial value, either zsh's default or a value set before this script is sourced.
# * iterm2_precmd is invoked
# * ITERM2_SHOULD_DECORATE_PROMPT is initialized to 1
# * ITERM2_PRECMD_PS1 is set to the initial value of PS1
# * PS1 gets our escape sequences added to it
# * Your prompt is shown and you may begin entering a command.
#
# Invariants:
# * ITERM2_SHOULD_DECORATE_PROMPT is 1 during and just after command execution, and "" while the prompt is
# shown and until you enter a command and press return.
# * PS1 does not have our escape sequences during command execution
# * After the command executes but before a new one begins, PS1 has escape sequences and
# ITERM2_PRECMD_PS1 has PS1's original value.
