Non-interactive fnm use -- avoid prompting to install version

[philipmat]

Problem: fnm use prompts to install version.

❯ fnm use 22
Can't find an installed Node version matching v22.x.x.
Do you want to install it? answer [y/N]: ^C

Would prefer: a way to disable this prompt, effectively the opposite of --install-if-missing and for fnm to return a non-zero exit code if it didn't use nor installed the specified version.

Scenario: I'm writing a CI script that wants to make use of specific versions, in an order of preferences, but not install any.
For example: fnm use 22 || fnm use 20 || fnm use 18 --install-if-missing

If it was just one, I could use echo "n" || fnm use 22, but it requires a lot more scripting to make the chain work due to fnm returning a 0 exit code.

I remember making “install if missing” by checking if stdout is tty. That should cover your case. I wonder why it isnt. Maybe because of the last piped command in your example which is actually interactive (it pipes to stdout/stderr which are interactive)

What a test case would be?
