YES! Casper brought tabs into it! Wahoo! We've got all the ingredients
here to beat the post count of the checked exception thread. It ran
for over 150 posts. Can we beat it?
I'll toss this one into the ring:
The ONLY right indentation scheme is to use tabs for indentation and
spaces for spacing. The following two rules may never ever be broken:
1. The character in front of a tab must be either (A): Start of File,
(B) another tab, (C) a newline. A tab anywhere else is an error.
2. 1 tab per semantic indentation.
3. Yes, this means you get mixed tabs and spaces if you want to line
up something (such as a line continuation). For all mixed cases, it's
always all tabs first, then all spaces.
As a natural result of these rules, changing tab size doesn't change
the way your code looks at all, other than in the most superficial
manner: The relative obviousness of each indent. That is dependent on
your font and screen size anyway, so it makes sense to leave the
rendering of it up to the editor, instead of hardcoding it.
I dare you to resist replying to this :)
NB: Tongue in cheek folks. The only right way to indent is whatever
you're comfortable with. The only wrong way is to get religious about
it.
