How to exit a shell script using gum

[jbmoorhouse]

Problem

Firstly, thank you producing such a great tool!

I'm having issues quitting a program using gum.

To Reproduce

Given the following shell script. If I press CTRL + C, this only quits the current gum step. i.e. in the example below, I have to CTRL + C 3 times.

gum confirm "foo"
gum confirm "bar"
gum confirm "baz"

Expected behavior

More of a question, is this expected? Is there a way to exit the program entirely?

Setup Info

OS: Ubuntu 20.04.3 LTS
gum version: v0.10.0

Hey @jbmoorhouse!

Yes, this is bound to happen, as gum is another process within the script.

You can propagate it by adding a set -e, e.g.:

#!/bin/bash
set -e 
gum confirm "foo"
gum confirm "bar"
gum confirm "baz"

That means that if anything inside the script has an exit code > 0, it will fail right away, so pressing CTRL+C (or replying "no") in any of the confirms quits the entire script propagating the exit code. All this to say that, in your script, if you don't wan't the script to on, say, replying "no", you'll need to handle the exit codes.

For reference, gum confirm:

• exit 0 on "Yes"
• exit 1 on "No"
• exit 130 on CTRL+C

Here's an example handling the exit codes:

#!/bin/bash
set -e

if gum confirm "Do you want some soda?" ; then
	if gum confirm "What about some chips with that soda?" ; then
		gum format "OK, here's your soda with chips!"
		exit 0
	elif test $? -eq 130; then
		exit 130
	else
		gum format "OK, here's your soda!"
		exit 0
	fi
elif test $? -eq 130; then
	exit 130
else
	if gum confirm "OK, no soda, what about some coffee?"; then
		gum format "Cool, here's your coffee!"
	elif test $? -eq 130; then
		exit 130
	else
		gum format "OK, just water then, incoming!"
		exit 0
	fi
fi

Hope that helps :)

Perfect, just what I needed. Thank you very much, closing

Is the exit 130 still working with the latest version? The script above is not working anymore to handle 130 exit code.

Does this work even for gum input as well?

Like when I try to assign a value to a variable via gum input,
and then I try to exit the program via Ctrl + C, it does not exit the program, and just runs.
