Re: too many lines too long

I am concerned that 80 character lines discourages the use of longerSymbolNamesLikeThis. Which I really like. On Mon, Nov 9, 2015 at 2:51 PM, Richard Eisenberg wrote:

At both school and at home I can fit 3 80-character buffers side by side, at a comfortable font size. Going up (even to 85 cols) would mean losing a buffer. (Or straining my eyes.) Of course I can deal with wrapped lines. But I still vote for 80 characters as a target, while allowing people wiggle room to miss this target.

The number 80 is with us for historical reasons, but I know I'm not the only one who still routinely uses 80-column buffers.

In my view 80 chars is too short. It was justified in the days of 80-column CRTs, but that just isn't a restriction any more. I routinely edit in a much wider window.

Clearly there's a judgement call here. But I'd prefer 120 cols say.

Hi devs,

We seem to be uncommitted to the ideal of 80-character lines. Almost every patch on Phab I look through has a bunch of "line too long" lint errors. No one seems to do much about these. And Phab's very very loud indication of a lint error makes reviewing the code harder.

I like the ideal of 80-character lines. I aim for this ideal in my patches, falling short sometimes, of course. But I think the current setting of requiring everyone to "explain" away their overlong lines during `arc diff` and then trying hard to ignore the lint errors during code review is wrong. And it makes us all inured to more serious lint errors.

How about this: after `arc diff` is run, it will count the number of overlong lines before and after the patch. If there are more after, have the last thing `arc diff` outputs be a stern telling-off of the dev, along the lines of

...

Before your patch, 15 of the edited lines were over 80 characters. Now, a whopping 28 of them are. Can't you do better? Please?

Would this be ignored more or followed more? Who knows. But it would sure be less annoying. :)

What do others think?
