Allow gum to work correctly with "gum spin $(...)" about gum HOT 12 CLOSED

Nonono :)
Thanks for creating it!

👍 We will try to fix this.

As a workaround you can make a script file and run that with gum spin ./file.sh

from gum.

Try and set the environment variable before gum, which should pass the entire environment on to the sub-command:

VARIABLE="foobar" gum spin command

from gum.

Also if you want to use the output of the command to the variable use --show-output and assign that.

VARIABLE=$(gum spin --show-output ....)

Hi. Thanks for super-quick response.
It's rather a bit different scenario:
gum spin --title="Getting possible options..." LIST_OF_POSSIBLE_VALUES=$(aws s3 ls ...)
But the idea with external script is quite useful. Thanks for that :)

from gum.

This should work:

LIST_OF_POSSIBLE_VALUES=$(gum spin --show-output --title="Getting possible options..." aws s3 ls ...)

from gum.

This should work:

LIST_OF_POSSIBLE_VALUES=$(gum spin --show-output --title="Getting possible options..." aws s3 ls ...)

It's not, sorry :) Tried that before and tried that again.

Ah, one more thing... What if the inner command output has to be processed with grep/sed/whatever?
I think the external script is the right way as otherwise the solution is too complicated (and actually not really required as the quite straightforward workaround is present).

Can you try that again with the latest code, I pushed a fix that should make it work now:
#95

If it doesn't please reopen the issue

You can write to a file instead of a variable to allow more global state sharing.

aws s3 ls > possible_options.txt

I've build gum from current sources. You're ritght, it's displaying spinner and gets data in the background. Cool :)
You're awsome, thanks!
