Discussion on: My Terminal Setup

Function prompt_customIcon is slower than it could be (due to forking) and isn't quite correct. Here's a fixed version:

function prompt_customIcon() {
  local -i currenttime=${(%):-%D{%H%M}}
  if (( currenttime > 1619 || currenttime < 421 )); then
    ...
  else
    ...
  fi
}

It's also a very good idea to prefix all your custom prompt segments with my_ to avoid clashes with future versions of powerlevel10k.

function prompt_my_icon() {
  ...
}

Thanks for the tip! What do you mean by forking?

It calls an external command (date), which is implemented as fork + exec. Both of these calls are very expensive and slow.
