    How do you indent: spaces or tabs?

    Another thread was about this, I was just wondering: how do you indent your source code?
    I prefer indenting with two spaces.

    4 spaces. I used to use tabs until I realized it made the source code look different depending on what application was viewing it.

    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    I bet a bunch of newbies are going to read this thread and be like "huh? wuzzat???".

    Anyway, one tab or 6 spaces.

    So, we need to periodically hold this poll so as to determine some trend?

    Actually, that's not a bad idea.
    I didn't know this poll already existed. Although, honestly, I'm not surprised.

    Well, there seems to be several threads about indent style, but the one that most closely matches this poll is... How far do you indent?

    I think this would be a good idea. It would allow us to see how everyone slowly trends from their imperfect indentation style, to the correct style of 4 spaces over time

    I use tabs (set to the width of 4 spaces) because we use Visual C++ exclusively for our coding and tabs are easiest to work with.

    On personal projects I often set my editor to convert tabs to spaces (still at 4 spaces per tab). For code I post on forums I have a macro that converts all tabs to 4 spaces that I run before posting since tabs don't look so good on these forums.

    I'd like to add that one space just isn't sufficient. On a side note, I wonder if anyone indents using only semicolens?

    I follow Linus's lead:
    Quote Originally Posted by Linus Torvalds
    Chapter 1: Indentation

    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 preferred way to ease multiple indentation levels in a switch statement is
    to align the "switch" and its subordinate "case" labels in the same column
    instead of "double-indenting" the "case" labels. E.g.:
    Code:
            switch (suffix) {
            case 'G':
            case 'g':
                    mem <<= 30;
                    break;
            case 'M':
            case 'm':
                    mem <<= 20;
                    break;
            case 'K':
            case 'k':
                    mem <<= 10;
                    /* fall through */
            default:
                    break;
            }
    Don't put multiple statements on a single line unless you have
    something to hide:

    if (condition) do_this;
    do_something_everytime;

    Don't put multiple assignments on a single line either. Kernel coding style
    is super simple. Avoid tricky expressions.

    Outside of comments, documentation and except in Kconfig, spaces are never
    used for indentation, and the above example is deliberately broken.

    Get a decent editor and don't leave whitespace at the end of lines.

    When I'm indenting blocks of code like functions, conditionals, etc... I use tabs.

    When I'm trying to get various parts of the code to line up (like when I have very similar lines of code and I want to emphasize their similiarity and clarify the different parts of each line, I use spaces (that way it doesn't get messed up if someone uses 4-space-tabs instead of my 8-space-tabs).

    edit: Linus Torvalds endorses my 8-space-tabs? YES!

    Who is Linus Torvalds?

    EDIT: Just found it on Wikipedia. Didn't look too impressive. But 8 space tabs surely look impressive on C++ generic programming...
