Add an option for non-error exit status mark + customization

[eadmaster]

I'd like to see the exit status even when successful, possibly with a green color
[ble: exit 0]

Also, i'd like to add an emoji to both error and non-error exits to make them more readable.

Example made via PS1 customization:

If you want to print the exit status for both cases of successful execution and failure, you may turn off the exit-status display from ble.sh by setting an empty string to bleopt exec_errexit_mark and instead print one by yourself. You can print your own exit-status information via whatever you like such as blehook POSTEXEC, PS1, or PROMPT_COMMAND. Here's an example using blehook POSTEXEC:

# blerc

# Turn off the exit status [ble: exit $?] by ble.sh
bleopt exec_errexit_mark=

# Print status
print-exit-status() {
  local exit=$?
  if ((exit==0)); then
    echo $'status: \e[32m0 ♥\e[m'
  else
    echo $'status: \e[31m'"$exit"$' ♦\e[m'
  fi
}
blehook POSTEXEC=print-exit-status

thank you, it is working as expected, i've made some changes to better suits my tastes (that's some tricky code to edit):

# Turn off the exit status [ble: exit $?] by ble.sh
bleopt exec_errexit_mark=

# Print status
print-exit-status() {
  local exit=$?
  if ((exit==0)); then
    echo $'\e[2mstatus: \033[2;32m'"$exit"$' \u2665\e[m'
  else
    echo $'\e[2mstatus: \033[2;31m'"$exit"$' \u1F615\e[m'
    
  fi
}
blehook POSTEXEC=print-exit-status
