Handy QR Generator: qrcode.show

Some days ago I was thinking about the possibility to have QR Codes on the terminal,and I was considering whether some ASCII Art with # and spaces would do the trick.

Then I discovered qrcode.show, which seems pretty much to address the displaying part:

Unfortunately… the embedded player for asciinema leaves some spaces that make it difficult to appreciate the result. Here is a snapshot of how I see it from my terminal:

The nifty thing is that it’s leveraging only three special characters, plus the space:

• FULL BLOCK █
• UPPER HALF BLOCK ▀
• LOWER HALF BLOCK ▄
• a simple space

This is a great idea, because terminal fonts are usually higher than wide, hence it makes sense to pack two pixels in a single character.

It’s a good starting point indeed…
