[ANN] QRCode on github

Need to generate a QRCode ? An old (but still relevant) project was available on smalltalkhub.

As I wasn't aware if it was already available elsewhere, I moved it to Github, including load instruction:

https://github.com/rvillemeur/QRCode

Unit test are all green on Linux.

Have fun.

Great, thanks. This is indeed a very well written project.

Hi Renaud,

your code is also based on the orginal version of Jochen Rick. Jochens code always worked but unfortunately had
only a few tests and was codewise hard to understand. Dont know if you just moved or also refactored and extended it.

I also once started with a clean reimplementation (also based on Jochens code but also checked barcode code
from Java/JavScript) - mainly to understand the algorithms. I also did not want to limit to QR but also other barcode,
includes proper packaging and more tests. Result is here:

https://github.com/astares/Pharo-Barcode

including also EAN8/EAN13 barcodes.

Had to put it aside for time reasons - but maybe this could be the base for a full and clean barcode library
for Pharo. I can move it to a community hosted location if more people want to join.

Thanks
T.

Re: [ANN] QRCode on github

I did some research on qrcode. There are some great libraries out there.

This one is great regarding implementation (and comments). That’d be possible to port or at least inspire (again look at the comments).

https://github.com/nayuki/QR-Code-generator/blob/master/python/qrcodegen.py

Also I felt in love with « artistic QR code »

Especially half tone QR code. Basically it needs usual qrcode generation then some other (longer) processing. The best library I found is again a python one. You should try it ! Orignal réa search is great to read too (http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/halftoneQR_sigga13.html).

MyQR

https://github.com/sylnsfar/qrcode/blob/master/README.md

pip(3) install myqr

myqr https://github.com -p github.jpg

Again there is not a real interest to reimplement it except for learning purposes !

That being said, I’ll happy to try your implementation Torsten (the version from Jochen Rick had some problems for me with big qrcode). QRCode are on my ToDo’s ^^

Cheers,

Cedrick
