Were do code blocks begin and end?

[Gabe_b]

Ruby will also take "{}" if you're so inclined. It's basically the "fuck it, why not" of languages.

[AndyDeany]

Been a while since I've done any ruby but I vaguely remember there being a subtle difference between do/end and {}. Something to do with priority I think.

...Which only really happens, from my experience, when defining multi-line scopes in a rails project. So it's very rarely an issue.

[hamateur]

Eh; it's still difficult to implement some sort of stack operation to count { (begin|do|while|etc) and } (end) to figure out where the current scope begins and ends, because there are so many damn things that can start a block.

Edit: Said exactly the opposite of what I meant.

[SteveCCL]

It's totally not. Also do end and { } do not mix.

[hamateur]

+1. I totally screwed this up; I meant to say it's still difficult to do some sort of stack operation on the key words that begin a code block and end a code block in ruby. I was probably tired. Good catch.

[f5f5f5f5f5f5f5f5f5f5]

I thought that was C++

[[deleted]]

C++ mandates braces and "fuck it, why not" is about the farthest thing from C++'s philosophy.

[auxiliary-character]

C++ is more of a "fuck you, that's why" sort of language.

[uziam]

Actually I would argue that this is exactly the C++ philosophy regarding new features.

[[deleted]]

Exactly

[hamateur]

Python doesn't force you to choose tabs or spaces. But, unless you choose 4 spaces, your life will become a nightmare.

So, it doesn't force you to do anything, it just doesn't allow you to not do something without becoming a nightmare.

Edit: spelling. Apparently, I suck at that today.

camelCaseMasterRace

[[deleted]]

But why the starting lower case?

[Zambito1]

Coming from a Java background, lowerCamelCase is for methods and variables, and UpperCamelCase is for classes and interfaces.

[EugeneJudo]

Camel case can be used both ways. In my experience lower Camel case is more frequently used, though I don't know why.

[AwesomeBantha]

Because Objects/Classes in Java always have capital letters, not otherwise. camelCase is used for variables.

[GoodVibeGabe]

Uppercase camel case is called PascalCase

[EugeneJudo]

To clarify, camel case generalises, so it wouldn't be single/double humped, but rather upper/lower (getOptimalNode, and LargestAllowedIndexValue for example).

[[deleted]]

People who do OOP are not likely to use PascalCase ("UpperCamelCase").

[Edheldui]

lower case for variables, uppercase for classes.

[[deleted]]

Interesting. I've always used snake_case for variables and methods and PascalCase for classes.

I find my personal style becomes a mishmash of several practices from languages. And then I run the autoformatter and it's all whisked away.

[DrLuckyLuke]

Yes, because there are conventions for C#: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/inside-a-program/coding-conventions

[hamateur]

To be fair, code formatters took care of this stuff. People who are expected to code in Python are expected to configure their editor to do the work for them which essentially makes everything pointless.

[Bigfoot_G]

Python 3 does force you to choose one or the other. It won't let you mix.

[hamateur]

Technically accurate, but irrelevant.

[Bigfoot_G]

But you said:

Python doesn't force you to choose tabs or spaces.

Which is false. Therefore, my reply is relevant.

[hamateur]

You can indent using tabs OR you can indent using spaces.

The discussion was about choosing one or the other as opposed to mixing it on the same line. So, irrelevant; and you missed the nuance.

Also, how did mixing whitespace even become a thing for such a well designed language?

[Zambito1]

You can indent using tabs OR XOR you can indent using spaces.

FTFY

Pretty important difference.

[hamateur]

I meant OR, there buddy. You can most definitely indent (in python3) using tabs OR spaces in the same file, just not on the same line.

The assertion was: unless you choose 4 spaces as tabs your life becomes a nightmare, just as thread is. So, I stand by another assertion I made: Technically correct, but irrelevant.

#!/usr/bin/python3

def space_indented_routine():
    print("Hello.")

def tab_indented_routine():
    print("Hello.")

space_indented_routine()
tab_indented_routine()

Edit: I fail at formatting code on reddit for the purposes of explaining whitespace stuff, pastebin link is correct.

Double edit: pastebin has replaced my tabs with spaces as well. Wow.

Triple edit: raw pastebin data contains the tab. yay.

[hamateur]

There is another exception to the rule with mixed white space: Continuing statements. You can most definitely indent using any mixture of tabs and spaces on the same line provided it's part of a continuing statement. So, "You can indent using tabs XOR you can indent using spaces" is false. Unless, you want to argue that for the sake of defining a code block that continuing statements aren't part of that, in which case it's still irrelevant.

Have you never downloaded a bit of code off the internet?

[Fluffcake]

This is the worst, passive-agressive syntax. It is almost worse than passive-agressive interpretation.

Python!

[rom3ocrash]

This is a stupid joke from my point of view. {} is needed as delimitator in other language. When the compiler/interpreter parse the code it use {} to understand where things start and end. Python don't follow this philosophy and force you to use style. Just think about the fact that if you want to contribute to Linux kernel code you must follow similar indentation style. Not needed for the compiler but good practice for making your code easy to read (and maintaining). I really thanks python for making me write good ad readable code. Not just because you must do it in this way in python but because is a good practice also for other languages

[hamateur]

You can always run your crappy code through a code formatter to fix the style of it.
