Is it possible to fix the 'empty line on terminal open' issue in this xontrib?

[anki-code]

Try to cut empty line here:

xontrib-prompt-starship/xontrib/prompt_starship.py

Lines 11 to 16 in 00e7c8b

	return __xonsh__.subproc_captured_stdout([
	'starship', 'prompt',
	'--status', str(int( __xonsh__.history[-1].rtn)) if len(__xonsh__.history) > 0 else '0',
	'--cmd-duration' , str(int((__xonsh__.history[-1].ts[1] - __xonsh__.history[-1].ts[0])*1000)) if len(__xonsh__.history) > 0 else '0',
	'--jobs', str(len(__xonsh__.all_jobs))
	])

i.e. "Using starship cross-shell prompt to rendering right sections" in xontrib-prompt-bar

Oh so simple, thanks!
I came up with a naive solution:

_FIRST_PROMPT = True

def _starship_prompt(cfg=None):
    global _FIRST_PROMPT
    with __xonsh__.env.swap({'STARSHIP_CONFIG': cfg} if cfg else {}):
        prompt = __xonsh__.subproc_captured_stdout([
            'starship', 'prompt',
            '--status', str(int( __xonsh__.history[-1].rtn)) if len(__xonsh__.history) > 0 else '0',
            '--cmd-duration' , str(int((__xonsh__.history[-1].ts[1] - __xonsh__.history[-1].ts[0])*1000)) if len(__xonsh__.history) > 0 else '0',
            '--jobs', str(len(__xonsh__.all_jobs))
        ])
    if _FIRST_PROMPT:
        _FIRST_PROMPT = False
        return prompt.lstrip()
    return prompt

Works fine unless the screen is cleared (Ctrl + L). Is there a way how to detect execution of the clear command, so I could add one more condition for the left strip?
Thanks!

I think you're using prompt toolkit for $SHELL and the first way is to search there.

Hmm, I didn't even know that prompt toolkit provides shell functionality, because I don't have any experience with this library. Is it possible to access ptk's API somehow from the prompt_starship.py file please?
