Google recently published a C++ style guide, containing all the rules that Google code adheres to. Many of the style tips are quite sensible, and well accepted by many developers out there. However, I was surprised to find the following rule:
Spaces vs. Tabs: Use only spaces, and indent 2 spaces at a time.
We use spaces for indentation. Do not use tabs in your code. You should set your editor to emit spaces when you hit the tab key.
I never really understood why so many people have such a hatred towards tabs. Is it just because they have seen code where some editor has mixed tabs with spaces (which of course results in a horrible mess)? Or do they have valid counter-arguments, even when tabs are used consistently?
