2 Spaces or 1 Tab, what's the standard for indentation in the Rails Community?

Question

I've noticed that most of the HTML/XML/HAML that gets generated from plugins uses 2 spaces instead of 1 tab. I use textmate and have tabs set to 4 spaces for HAML/HTML/XML and 2 spaces for Javascript/Ruby, but I only have to press the tab key once to get nice indentation. Pressing the space bar twice and delete twice seems like too much work :p.

Do you manually type two spaces, or is some middle layer converting tabs to two spaces? Or do just a few of you use tabs?

Answer 1

2 spaces is generally agreed-upon.

Answer 2

2 spaces. Even for the plain Ruby kids.

Answer 3

2 spaces is the convention for Ruby which Ruby on Rails is based upon.

Answer 4

In more practical terms, if you use mutliple OS and editors ( such as at work I used RubyMine on Win XP and TextMate on my MacBook at home and one of our developers uses Notepad ++ and another Aptana and we even have one who uses Netbeans, all of these editors interpret tabs differently - different indentation, but 2 spaces are always 2 spaces. Also if you ever use HAML or if you need to copy paste your code into some websites that try to colorcode your code, 2 spaces are essential.
