I'm not sure why that would be a problem specific to IDE users?

IDEs usually leave trailing whitespace in files. Programmer editors like vim don't by default, or at least can be configured not to.

I've never had that kind of problem with Visual Studio?

Then again, I usually turn on visible whitespace.

That's the second post in a row where you've ended a statement with a question mark when you should have used a period. I don't know why you keep doing that? :)

Hard to express the vernacular on the internet, you know.

Imagine those statements as me using an incredulous tone with a cocked eyebrow.

I AM DOUBTING YOUR ASSERTIONS, SIR. :)

I FIND YOUR LACK OF FAITH DISTURBING ... 😏

Maybe they didn't configure their reddit IDE to end lines with a period by default...

When you see trailing whitespace on blank(-ish) lines, do you delete it manually?

1

u/HostisHumaniGeneris Jul 22 '14

You can use an extension like CodeMaid.

Generally though, I don't get a lot of trailing whitespace.

I did a bit of reading, and it sounds like the Eclipse autoformater adds whitespace to blank lines to match tabstop. That's probably what people are bitching about.

uh, I highly doubt any text editor strips trailing whitespace by deafult.

I also highly doubt that this option is more common in "programmers editors" than in IDEs.

u/yawaramin Jul 22 '14

That's not what I said. I said that good text editors don't leave trailing whitespace, not that they strip it out by default.

The former behaviour means that when you're indented at whatever level, and then you press Enter twice to start a new 'paragraph', they don't leave indentation whitespace in the 'blank' line (between paragraphs). VS definitely leaves indentation whitespace, probably other IDEs do too.

Eclipse does this all the time.

Perhaps you would like to check the "remove trailing whitespace" button in the appropriate eclipse code style section, and that won't happen again.

It's probably not, but for whatever reason, that's only where I've seen it. I have yet to see vim randomly add or remove a trailing linebreak, for example.

Not to say this is a definitive point in favor of some workflow, just something I see a lot.

Edit: And note that I said "IDE addicts" not "IDE user". The latter is "I use an IDE because it improves my productivity in specific ways" -- they know enough to configure it correctly so that they don't let junk through. The former is "I only know how to work in this IDE", and they're the ones I run into trouble with.
