Here's an example config section for Starship:

def create_left_prompt [] {
    starship prompt --cmd-duration $env.CMD_DURATION_MS $'--status=($env.LAST_EXIT_CODE)'
}

# Use nushell functions to define your right and left prompt
let-env PROMPT_COMMAND = { || create_left_prompt }
let-env PROMPT_COMMAND_RIGHT = ""

# The prompt indicators are environmental variables that represent
# the state of the prompt
let-env PROMPT_INDICATOR = ""
let-env PROMPT_INDICATOR_VI_INSERT = ": "
let-env PROMPT_INDICATOR_VI_NORMAL = "〉"
let-env PROMPT_MULTILINE_INDICATOR = "::: "

Now restart Nu.
