Hi all, As announced previously I ported the builder back to Magritte, as I believe it was a missing piece in Magritte. A mail does not suffice to give the details, and in the past I did 2 presentations on this topic (dry-ing Magritte, https://www.slideshare.net/esug/drying-magritte?next_slideshow=1). I also extended the tutorial (build in with QC-Magritte, load QC-Magritte, and start a web-browser on http://localhost:8080/) with a chapter “technical details” where I made another effort in explaining why we need builders. If this gives questions, please ask them. Also I am not 100% sure a builder is the correct term: so if there are people with better suggestions, please post them. The coming weeks I will fill in the last blanks: - add testcases specific to the builder. The old ones still run, ensuring no builders == no change. - more work on tutorial. Of course it motivates me, when people comment or ask questions, so I know it is used. So thanks Udo for asking a question concerning QCMagritte, this helped me at least finish this far. Regards, Diego
