I thought python allowed whatever indentation you wanted as long as it's consistent?

It does, but most style guides and autoformatters will use 4

Python is one of the few languages with an official style guide, I think that guide says 4 spaces.

Tabs!

[–] [email protected] 11 points 3 months ago (2 children)

I've set tabs to four spaces in vim because who the fuck defaults tab to eight spaces. That shit looks alien and pushes text off the screen fast.

Linux uses 8 spaces. Excerpt from the official style guide:

Tabs are 8 characters, and thus indentations are also 8 characters. There are heretic movements that try to make indentations 4 (or even 2!) characters deep, and that is akin to trying to define the value of PI to be 3.

Rationale: The whole idea behind indentation is to clearly define where a block of control starts and ends. Especially when you’ve been looking at your screen for 20 straight hours, you’ll find it a lot easier to see how the indentation works if you have large indentations.

Now, some people will claim that having 8-character indentations makes the code move too far to the right, and makes it hard to read on a 80-character terminal screen. The answer to that is that if you need more than 3 levels of indentation, you’re screwed anyway, and should fix your program.

In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep. Heed that warning.

The reasoning seems sound, but I still prefer 4 personally.

I don't develop kernel modules, I use python. That's pretty interesting though.

I set my clang-format to tabs only (actual tabs ASCII 0x9, no alignment and there is a continuation tab instead), then anyone can set their editor to whatever tab length they feel like and look at their code however they want.
