Do you use spaces or tabs in your code for indentation?

Apparently, StackOverflow says you get paid better for spaces than tabs!

(I'm not sure whether to take this seriously or not, or, if serious, how much salt to consume simultaneously...)

Me, I just let my editor do my indenting for me, and it produces spaces, so I'm good. :)

    Apparently, StackOverflow says you get paid better for spaces than tabs!

    This interpretation of statistical data looks like some sort of post hoc ergo propter hoc fallacy to me.

    More experienced and better programmers get better pay, and they surely have seen lots of source code with messed up indentation, so they use spaces.

    For instance, one schmock does set tabstop=4 in vi, the next goes WTF?? and is told to set ts=4 to get the intended (indented :-) view, but has set expandtab in their .vimrc, edit, save. The next one pages the file with less(1) and seriously goes WTF.

    I use spaces, except where tabs are mandatory. There are a couple of config file formats which absolutely demand tabs.

    More chars in the source file, more volume, better pay :-P

    perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
      Yes, I think someone went on a fishing expedition. I wonder if space-use correlates with online-forum-use? It's irritating when your posts get tabdamaged.

    Since I'm retired and no longer get paid for code, I use tabs because they take less disk space (snicker).

    Then for pasting to perlmonks I have the following line in my .vimrc (vim forever!)

    nnoremap QQ :w !expand -2 \| (echo \<code\>; cat -; echo \</code\>) \| + xclip<CR>

    which converts tabs to spaces and wraps the whole program in a code block and sticks it in the clipboard for immediate pasting.

    The idea that you can only choose one is the root of the problem, IMO.

    Tabs are indentation, spaces are alignment. Then you can set your tab width to anything and it all works.

    If tab stops could be globally set at PI spaces wide, then this would be obvious.

    In the end, you just go with the flow and clone whatever style is already there to get money.

      The idea that you can only choose one is the root of the problem, IMO.

      I'd say that the root of the problem is unfamiliarity with old typewriters, and the fact that the convention of tab stops defaulting to 8 spaces can so easily be overridden in the wrong way, yielding disastrous results.

      Tabs are indentation, spaces are alignment.

      The other way round that is. On the old typewriters, you could set stops for alignment of data skipping thus a fixed amount of spaces, mainly for filling out tables; whereas the indentation in typesetting e.g. at the beginning of a paragraph was done with spaces.

    It makes sense, since the technocrats probably analyze code by how much actual text-code there is. Since a space is actually holds a character space, your code's character count is higher with spaces.

    What peeves me is the little useless dots many editors insert into spaces to show they are not used.


    I'm not really a human, but I play one on earth. ..... an animated JAPH
      I think I always used tabs, but seems that my primitive editor of choice convert them into 2 (?!) spaces.

      Anyway I'll pass all my codebase through  perl -i.bak -e "s/\t+/' ' x (length($&) * 8 - length($`) % 8)/e" and monday I'll ask my boss for more money.. ;=)

      L*

        Don't sell yourself short - go for 32 instead of 8. Have to justify that widescreen monitor somehow.

    Yes auto-indenting is a bliss ... but even better if your editor knows how to back-delete spaces till the former tab stop.

    update

    See also emacs M-x untabify changes all tabs in the region to appropriate numbers of spaces.

    Autoindent and tabs. I have learnt to keep it simple and mechanical. "Smart" editor mode did not work for me; the logic goes:

    • Text alignment is separate from indentation. E.g. a char table[] definition, where you put spaces before the small numbers to make the columns align. The editor does not know where indentation ends and whitespace starts.
    • The "smart" editor makes mistakes. Having to guess what happens if I hit that Backspace key amounts to an unacceptable cognitive load / annoyance.
    • My fingers find Tab and Backspace easily, I'll never use any other keys to change indentation.
    • Manual indent changes are effortless and "automatic". Somehow being assertive and in control goes well with the flow of thought.
    • Consequently, I encode indent level as tabs in the source files.

    Of course, using tabs is not mandatory, but to sum this up:

    People who do not know of indentation character are bound to reinvent it.

    ps. Oh by the way, should you want to increment the troll-level, the next question to ask is if one uses braces for scoping.

    pps. Curiously, Unicode has a number of space characters, but none wider that 1 em...

    Ugh .. this debate has been going on for decades. To me, it was just something to generate traffic .. aka "Someone is wrong on the Internet!" Tie it to "Who gets paid better?", and you've got a burst of traffic for a week.

    Meh.

    This is why I continue to write all of my code on an Apple ][!! Its 40-column uppercase-only screen ensures that I can fill up the same amount of square-footage using only half as many characters, thereby doubling the amount that I get paid!
