Expected Behavior

No deprecation warnings

Additional context/Screenshots

A little ahead here but I wanted to make a note of it, in elvish 0.18.0 (unreleased) and I think versions >= 0.17.0, starship yields a slew of deprecation warnings when bootstrapping starship. To be expected, elvish changed some stuff. They provide to automate the upgrade but in my experience you probably want to do this manually.

Starship Configuration

<unknown config>

[ryanjafari]

Otherwise seems to work fine... I'd ignore warnings if I knew how to configure that.

[davidkna]

It looks like some of these deprecation warnings cannot be fixed while retaining support for the current stable version (like the new lambda syntax). Do you know if there's an option to hide these warnings for the time being?

[ryanjafari]

eval (starship init elvish) 2> /dev/null seems to work...

[zQueal]

Just ran into this issue.

eval (starship init elvish) 2> /dev/null

Seems to be a workaround for right this second.

[zQueal]

Completely broken on windows as there is no way to quiet output ala 2> /dev/null.

[davidkna]

eval (starship init elvish) 2> nul works on Windows, or you could try using the init script from #3310.

[zQueal]

Very weird! I actually tried this yesterday with 2> NUL and for whatever reason, it didn't work. Beginning to think I didn't refresh the environment now...

Either way, thanks!
