Usually I use 2 spaces indent for all files. But for some project I must use tab character instead.
I've found .idea/projectCodeStyle.xml in project directory. It looks like what I want. I've replaced all <option name="USE_TAB_CHARACTER" value="false" /> to <option name="USE_TAB_CHARACTER" value="true" />, restart RubyMine, and nothing changed.
What I'm doing wrong?
I use RubyMine 2.0 beta 2 build 1480 on Mac OS X.
