Convert PyQRCode generated SVG to ASCII art
Project description
Convert SVG images containing barcodes generated by PyQRCode to ASCII art, for displaying in a terminal.
Because I’m a weird person who reads mail using Mutt over SSH in a terminal, and sometimes people send me QR codes for setting up TOTP authentication.
Example:
$ python3 >>> import pyqrcode >>> qr = pyqrcode.create('Hello world!') >>> qr.svg('hello.svg') $ qr2text --white-background hello.svg █▀▀▀▀▀█ ▀▄█▄▀▄▀▀▄ █▀▀▀▀▀█ █ ███ █ ▀ █▄ █ █ ███ █ █ ▀▀▀ █ ▀▀▄▄▀ ▀ ▄ █ ▀▀▀ █ ▀▀▀▀▀▀▀ █▄█▄▀▄▀▄▀ ▀▀▀▀▀▀▀ ▄▄▄▄▀▀ ▄▀▄▀██▀▀▀ ▀▄█▄▀ ▀ ▀▀▀▀▀▄▀▀▄▀▄▀▄ ▀▀█▀▄ ▀█ ██ ▄█▀▄▀ ▀▀▄ ▄██▄▀ ▀▄ █▄ ▀ █ ▄ ▀▀▀█▄ ██▀█▀██▀█▄▀█ ▀ ▀ ▀▀▀▄█▄▀▄█▀▀█▀▀▀███ ▄ █▀▀▀▀▀█ ▄ █▀▄▀██ ▀ █ █ █ ███ █ █▀▄ ▄ ▀▀█▀▀▀█▀▄ █ ▀▀▀ █ ▄▀▀▀▀ ▀ ▄█▄█ █ ▀▀▀▀▀▀▀ ▀ ▀▀ ▀▀ ▀ ▀ ▀ Hello world!
Note: you may have to tell qr2text whether your terminal is black-on-white (–white-background) or white-on-black (–black-background). Some QR code scanners don’t care, but others will refuse to recognize inverted QR codes.
Note: for QR code decoding to work you need to have libzbar installed on your system (e.g. sudo apt install libzbar0 on Ubuntu).
Synopsis:
usage: qr2text [-h] [--version] [--black-background] [--white-background] [--big] [--trim] [--pad PAD] [--decode] [--no-decode] [--encode-text ENCODE_TEXT] [filename ...] Convert PyQRCode SVG images to ASCII art positional arguments: filename SVG file with the QR code (use - for stdin) options: -h, --help show this help message and exit --version show program's version number and exit --black-background terminal is white on black (default) --white-background, --invert terminal is black on white --big use full unicode blocks instead of half blocks --trim remove empty border --pad PAD pad with empty border --decode decode the QR codes (default if libzbar is available) --no-decode don't decode the QR codes --encode-text ENCODE_TEXT generate a QR code with given text
