QR codes on terminal for passing things to phone…

ie `qr foo`

```

#!/usr/bin/env python3

import os, sys, pyqrcode

p = ' '.join(sys.argv[1:])

if not p:

print(f'{sys.argv[0]} data-for-qr')

sys.exit(1)

q = pyqrcode.create(p)

print(q.terminal())

```

Nice! I use qrencode for that: (testing code formatting here)

```

$ qrencode -tutf8 'LNURL1DP68GURN8GHJ7MRWVF5HGUEWWFHHXETWVFSH2MFWWDJJ7MRWW4EXCUP02DU42NJGDVTHM57P'

Ok, that sucked. This is how it looks in the terminal:

Testing a smaller qr:

```

$ qrencode -tutf8 'foo'

I already had qrencode installed, but didn’t even know it supported displaying in terminal. I always wrote to an image file 🤦.

Well now I added

alias qr='qrencode -tutf8'

to my bashrc and got the comfort of just typing qr followed by the text to be encoded or piping to qr straight from the terminal. Thanks for the idea guys :)
