I am flexible about how wide my editor is. Pretty much all code I read bounds itself to some sort of limit around 80-120 characters. If there are a few individual lines that exceed the current editor width, I can scroll. I don't have to work with any codebases that have ridiculously long lines.
To be honest, I don't often read such code, or I try to run it through a formatter prior to reading. I guess I should have said that I _generally_ don't have soft wraps enabled. Sometimes I just have to plug my nose and soft-wrap.
The problem is that it doesn't work, even on mobile, whether you're posting code or the Declaration of Independence.
At its heart, this web site is about communicating information. The current state of the code block fails at that mission.
Would you use an IDE without word wrap?
