# 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.
|

# really adds up. It would be great if we could do something like this at

# PS1="$(iterm2_prompt_prefix)$PS1($iterm2_prompt_suffix)"
|

|
|
# 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

|
|
# 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
|
