Re: [Pharo-users] Loading Seaside and Magritte in Pharo8 - baseline load conflicts

by Sebastijan Kaplar

Thanks everyone, I guess Iâll go with it. However, I can say #onConflict or #onConflictUseIncoming when loading the project, eg. Metacello new baseline: #NewWave; repository: 'github://skaplar/NewWave:development <github://skaplar/NewWave:development>'; onConflictUseIncoming; load. Iâm interested to know can I do something like that in my baseline configuration, so that the build does not fail?

Yes, because Metacello does not recognise this naming convention. Instead, Metacello has/had the question mark as a notation (e.g. v1.4.?) to allow this but it also means that it will try to detect the latest version which was blowing up the GitHub rate api and thus it became unusable :( There is a need to fix package versioning and dependencies, but I am not following enough to know if there are efforts going on to improve package management. > I don't know if this is a bug or by design.

Re: [Pharo-users] [ANN] QRCode on github

by CÃ©drick BÃ©ler

I did some research on qrcode. There are some great libraries out there. This one is great regarding implementation (and comments). Thatâd 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 Â« artistic QR code Â» 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 rÃ©a search is great to read too (http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/halftoneQR_sigg…) 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, Iâll happy to try your implementation Torsten (the version from Jochen Rick had some problems for me with big qrcode).

Re: [Pharo-users] [ANN] QRCode on github

by Torsten Bergmann

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.
