Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
I want to be able to run the guix-install.sh non-interactively[1] like this:
echo "yy" | guix-install.sh
(One "y" for "Press return to continue..." prompt, the other "y" for
"Permit downloading pre-built package binaries from the project's build
farms? (yes/no)" prompt).
Currently, the `read` in welcome function reads both the "y". I updated it to
read just one character.

Not quite, but
$ echo -e "y\ny" | guix-install.sh
will. Or the more conventional
$ yes | guix-install.sh # untested
providing guix-install.sh doesn't choke on that infinite stream of
"y"s. Which it might, and even if it doesn't now, there's no
guarantee that this dirty hack won't break the future.
If this is something we want to support, it could be done more
better through a '--non-interactive' or '--force' flag that skips
these and any future prompts at the source.
Non?

This is actually something I was thinking of a while ago. I use github
as a mirror, and I definately wouldn't be against using their CI system
to install guix, 'guix pull', 'guix build -f guix.scm'.

Message #20 received at 33134 <at> debbugs.gnu.org (full text, mbox):
The following patch series adds "auto yes/no" switch to the guix-install.sh
script.
It works like this:
guix-install.sh -y
[ for non-interactively answering 'yes' to all y/n prompts ]
guix-install.sh -n
[ for non-interactively answering 'no' to all y/n prompts ]
If either the -y or the -n switch is provided, the script will skip the
"Press return to continue..." prompt.
I'm not a bash expert; if there is a better way to do this, let me know. I
would be happy to refactor and send a fresh patch series.

Why "export" ? Now all the child processes get it, making their environment
different from before. This makes parse_args have system-wide side effects.
If we wanted to export it, we could do it explicitly after parse_args has
been called.

Does this make it conditionally interactive? Would it be better to "exit 1" here?

While it's nice for the interactive user, doesn't this break
yes | ./guix-install.sh
because now it doesn't wait for the newline?

Remove the `export`.

Yes, it would break `yes | ./guix-install.sh`. I've removed `-N 1` from the `read` statement.

When the user is running the script interactively and answers, say "Oui", we
arrive at the:
*) _msg "Please answer yes or no.";
case. After this, we go to the beginning of the loop:
[[ -n $yn ]] || read -p "Permit downloading pre-built package binaries from the project's build farms? (yes/no) " yn
Since $yn is "Oui" `[[ -n $yn ]]` will evaluate to true, the user won't be
prompted again, we'll go back to:
*) _msg "Please answer yes or no."
and this will repeat infinitely.
The `yn=""` was added:
*) _msg "Please answer yes or no."; yn=""
to reset the value of yn, so that `[[ -n $yn ]]` will evaluate to false and
the user will be prompted again for answer.

The guix-install.sh saw some imrovements in v1.3.0 that makes it support
the non-interactive 'yes | sudo ./guix-install.sh' use case. I think it
obsoletes this patch.
Closing, but feel free to send a new patch series if I missed anything.
Thank you,
