I have just started with ruby, and something that I have observed is
that most of the code is indented with 2 spaces. Having programmed some
time with C# and python, it's very strange to me so few identation. To
me 4 spaces is much better to read. Is there something like a style
guide in ruby that says that you should use 2 spaces or is it all right
using 4 or 3 spaces? What do you use in your code?

Thank you for your answers

Hi Alfonso,

indentation with 2 spaces is a non-written standard in Ruby. I use 2
spaces.

I use 2, 3 and 4 depending on who I'm working with an what I'm working on. I
think readability studies have shown that 4 is the best for most people, but
some companies (like Google I believe) have style guides that require 2.

I'd say it's mostly a personal preference thing. I started using
2-spaces when I started coding in Clipper many years ago.

I use 2 spaces, which is the Ruby tradition and custom. I don't think
there's anything in the standard library that does otherwise.
Whatever language I'm using, I don't like to have my code look like
David Black code, but rather like anonymous, standard, boring code
that uses the most common stylistic conventions for that language. If
you're more into making a statement about your own sense of style, you
can indent more

This is just an guestimation but I think Ruby went 2-space because the
most common keyword that takes a block is only three letters long:
'def'. So any more than 2 spaces of indention and you're past the end
of that word, which makes it look a little off kilter.

Use whatever indentation looks right to you, and don't let anyone
bully you into doing it otherwise. I indent by three spaces and don't
intend to change.

I agree. Use what you like on your personal projects and of course follow your
company's indentation policies when coding at work. I think this is common.
I've heard that Guido Van Rossum (of Python fame) indents 4 spaces for his own
personal programs and 2 spaces when coding for Google.

Best of luck,
Brad

That's what it's really about: that there is a traditional coding
style -- a "Rome". I think it's useful for it to be mentioned, not so
that no one ever deviates from it, but so that people who prefer to
use a language's traditional style will know that Ruby has one. That
sometimes gets overlooked amidst the excitement of how liberal the
parser is, etc.

One of my favorite things about Rails, and I think one of the
shrewdest things the Rails team has done, is that it's written for the
most part in a very vanilla coding style. Not all the code is
vanilla, of course But it blends very well with the standard
library and so forth in style.
