Forcing yourself to indent code?

How do you do it, guys?
I seem to only really indent my code when I use python.

tl;dr how can I improve my coding style?

... It's just habit man.

The thing is, Notepad++ used to have this function: re-indent C code.

It was EPIC and worked on any C like language (PHP, Java, whatever)

I now do Ruby/Rails development and I haven't found anything that'll reindent it for me.

The problem is that my text-editor at home uses 3-space soft tabs; and my editor at uni uses 5-space hard-tabs. So they fucking HATE working with each other.
