I don't understand the hate for "kilometer-long" lines (say in the 120-200 char range). My screen is much wider than it is long, so having longer lines allows me to fit more code onto the screen at once (which is fantastic for readability). Also, sometimes the extra content is uninteresting. And it makes sense to hide it away where it's only sometimes seen.

I'm modern, and a 120 char line is not kilometers long. It's in the range for modern stuff (yep, I'm an advocate for dropping 80 chars). km long lines start at 200 chars IMHO. To me, too long lines actually hinders readability:

- kilometer-long lines makes your eyes travel a lot more to read what is happening. travel is not that an issue, but context is. it is quite hard to get at a glance e.g. the argument list of a function. or know if e.g. a specific parameter is in the argument list.

- I almost never have my editor's viewport set to kilometers. It's usually in the ~110 chars range to fit multiple files at once (two side-by-side on 1080p, three on 1440p). Not that I am editing three files at once, but I'm usually editing the middle one with other files on the side for context and reference. In such a setup, the line ends up wrapped anyways, but with ugly wrapping that does not match indentation and in the middle of words.

As for hiding it, that's what editor folds are for.

Anyways, I guess we found bikeshedding topic not solved by formatters :D

Wider screens can also be used to have more code files or sections of the same file side-by-side. You can get two, three, sometimes four 80-char width files very nicely side by side.
