# (issue 4160).
|

# *BOTH* of these options need to be set for the DEBUG trap to be invoked
|

# in ( ) subshells. This smells like a bug in bash to me. The null stackederr
|

# redirections are to quiet errors on bash2.05 (i.e. OSX's default shell)

# where the options can't be set, and it's impossible to inherit the trap
|

# into subshells.
|
||||
# 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. If you have anything that's using the Debug Trap, change it to use
|
||||
# preexec. (Optional) change anything using PROMPT_COMMAND to now use
|
||||
# precmd instead.
|
||||
#
|
||||
# Note: This module requires two bash features which you must not otherwise be
|
||||
# using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. prexec_and_precmd_install
|

# will override these and if you override one or the other this will most likely break.
