Weird question: Do you leave a blank line at the bottom of each file when you program?

I have atom editor setup to remove all trailing white-space and new lines on save .. so no.

Nope

Yes, because that looks nicer in the github diff viewer.

Yes, because of lint. But I can see its usefulness in case of needed concatenation

Ye/, because vsCode does it and github stops complaining.

Till completion yes. At the end I like to trim this spaces and makes code sexy.

Every File gets a "#end of File" line

Always try to. Ms word spoiled me to ALWAYS leave a trailing empty line after images, tables, other objects bcz if you don't you'll have trouble inserting text below the object afterwards. I got into a habbit of leaving trailing newlines and paying xtra attention to additional whitespaces - all thanks to ms word.

@netikras is MS WORD your IDE of choice?

IDLE and Atom automatically do it for .py files

Just to shut the f* up f*ing eslint... there is no thing that I hate more (and love more) than eslint. F*ing beautiful bastard. Pimping my code and stuff.

POSIX definition of a file is (something like): lines of characters.

POSIX definition of a line is zero or more characters ending with a newline character.

By that definition, the empty file contains one newline character. And every file ends with one too.

I use Prettier which automatically formats *all* my code, and since prettier inserts a newline the answer is yes.

The IDE does what the IDE does.

no, but my IDE occasionally adds it (or it just gets there somehow via my editing), and quite the opposite: every time I notice it, i delete it. because I have some OCD tendencies, and dammit, EOF==EndOfCode==ClosingBrace!

@donnico I used to write a lot of texts for university and college. A LOT! So no, word isn't my ide

I used to simply not care about that final new line. I recently told VS-Code to care for me (in order for every file to be styled the same) so the situation remains unchanged. I still don't care ¯\_(ツ)_/¯

@eeee THIS! THIS IS THE REASON! Try using any POSIX tools without a trailing line break, and you will curse yourself to death wondering why things don't work as expected. And it is not just POSIX, Python's PEP8 says the last char of a file has to be a line break. ALWAYS END YOUR FILES IN A LINE BREAK (and thank me later 😉).

No my IDE does

No, imho having that line is kind of ugly. I have a visual studio plugin for refactoring which I primarily installed to remove those lines automatically.
