[feature request] add option for `gum spin` to dump output on error about gum HOT 7 CLOSED

Hey @jackmac92, I think this is a really great idea. Let me/us think a little bit more about it / how to implement it (default behaviour vs opt-in, etc...).

Thanks for sharing the chronic tool, btw!

Also, if you want a quick and dirty version of this functionality while we think about it, you can do this (on gum HEAD)

gum spin --show-output -- <command> >/dev/null

This will only display the stderr and not the stdout which should generally only output errors and be quiet if there are no errors

I'm piggybacking a little, but I'm realizing that this is close to what I want. I want to display a gum spinner while I run a long-running process whose output I want/need. That is, I'm trying something like:

gum spin -s points --title "Fetching list of sites..." -- someLongCommand > output.txt

What I really want is to display a spinner while someLongCommand writes its output to a file. So, would there perhaps be a flag to also allow the output to pass through? Or to add a --output-to-file option or something?

@chrisfromredfin That should work but you need to use the --show-output to redirect the output to the file (also make sure you're on the latest version of gum)

Ah sorry, I think the change that fixes this is not on v0.4.0.

@chrisfromredfin I think if you build on the latest code (including this commit: 4e61c12), the spinner will not be included in the file.

We will likely make a new release soon.

Yes, just confirming that with a HEAD build it works! Excited for a new release. :)
