At an old place of work, someone wrote an awk script that parsed strings using regex from a CSV file, and it generated JavaScript code automatically. It was ~5000 lines of awk script, it was beautiful. I understood it after a couple of weeks, I was in charge of maintaining it, super interesting.
In my part of QC, the only "Loblaws" around me is a Maxi, it's pretty cheap certainly one of the most affordable groceries here. But I can go to a nearby SuperC just to boycott Galen.
