ble/prompt: Undefined named sequence: \q{user/currentmode}

I get this as a message in the top right corner on every bash startup. I use the set-up-status-line function to get the current vi mode so I can have it displayed in my prompt (but NOT in a modeline or status line). It works but the error message is very annoying so any solution, including a dirty hack to supress or otherwise get rid of the message would be very appreciated. Thanks.

My Config:

# 
# Ble.sh config file
#

# Use vi(m) keybinds
bleopt default_keymap=vi

# Disable bell
bleopt edit_bell=vbell
bleopt edit_vbell=

#\q{keymap:vi/mode-indicator}  # Example result: -- INSERT --

You can use \q{user/currentmode} only after you define the function ble/prompt/backslash:user/currentmode. In the above setup, you define the function ble/prompt/backslash:user/currentmode through the keymap_vi load hook, which is called after precmd and the first prompt. You use \q{user/currentmode} in precmd, but the function ble/prompt/backslash:user/currentmode is not defined for the first call of precmd. This causes the error.

To solve the problem, for example, one may consider defining the function ble/prompt/backslash:user/currentmode outside the keymap_vi load hook. However, there is a reason that the above ble/prompt/backslash:user/currentmode was defined through the keymap_vi load hook: the function ble/keymap:vi/script/get-mode called by ble/prompt/backslash:user/currentmode is only available after the vi module is loaded. Then, you can use ble/function#try ble/keymap:vi/script/get-mode to call ble/keymap:vi/script/get-mode only when it is available.

function ble/prompt/backslash:user/currentmode {
  local mode=
  ble/function#try ble/keymap:vi/script/get-mode
  case $mode in
  (*n)  ble/prompt/print $'\e[1mNormal\e[m' ;;
  (*i)  ble/prompt/print $'\e[1mInsert\e[m' ;;
  (*v)  ble/prompt/print $'\e[1mVisual\e[m' ;;
  (*V)  ble/prompt/print $'\e[1mV-Line\e[m' ;;
  (*^V) ble/prompt/print $'\e[1mV-Bloq\e[m' ;;
  (*s)  ble/prompt/print $'\e[1mSelect\e[m' ;;
  (*S)  ble/prompt/print $'\e[1mS-Line\e[m' ;;
  (*^S) ble/prompt/print $'\e[1mS-Bloq\e[m' ;;
  (R)   ble/prompt/print $'\e[1mRPlace\e[m' ;;
  (^R)  ble/prompt/print $'\e[1mVPlace\e[m' ;;
  (*)   ble/prompt/print $'\e[1m??????\e[m' ;;
  esac
}

Adding that function outside of the hook fixes it! Thanks. (Also, I removed the user/currentmode function from the keymap_vi load hook as it's not needed anymore and it still works). Closing this issue. Thank you!
