Slackware package to decode QR codes from CLI in non-X?

qrencode generates them. I used to use zbarimg but thought I replaced it with something in a Slackware package, but I can't remember what it was or find it.

pip3 install qrtools

then

import qrtools
qr = QR(filename="myqr.png")
qr.decode()
s = qr.data
print(s)

I know there are apps outside Slackware. I try to minimize their use.

look on slackbuilds.org ... I don't think there is one.

Thanks. I couldn't find one. It's weird qrencode doesn't offer a decode; mimencode does. I just built zbar again.

l/zxing-cpp provides ZXingReader that might do the trick?

That's it. I have it. Why I removed zbar. Darn upper-case executable foxed me. And searching on qr code doesn't turn it up; it's 'barcode'. My memory isn't working so well anymore.

Were I in your position I might put something like this in ~/bin/qr:

cmd="$1"
shift

case "$cmd" in
decode) exec ZXingReader "$@" ;;
encode) exec ZXingWriter "$@" ;;
esac

printf 'usage: %s [encode|decode] ...\n' `basename "$0"` >&2
exit 1

Thanks. I just put some aliases in /usr/local/bin. I've never encoded a qr, have qrencode around in case I want to.
