Tab and indent = 4 is consent among the Java users @ cloudcontrol (i.e. do you think it's OK to merge without further discussion)?

@schu lets then use this pull request to finally decide. I am personally strict about spaces instead of tabs - this formatters use spaces.

Perfect. I go with whatever you decide, as long as it's consistent and easy-to-setup for reluctant Java users like me. We should mention this in the core README when it's merged.

I personally prefer TAB over spaces (exception python because PEP8 defined spaces), because this enables you to define in your IDE how you want to have it presented.

But I think this is should be a dev team decission - no hard feelings as long as my formatter takes care

Just to make it clear - this is so far only Intellij formatter.

I'm for 4 spaces but I would wait for Alex's and Stefan's opinion since they use it too.

I'm for tabs, just like Dimitris https://github.com/cloudControl/core/commit/c7488ffedf6d06876b3cd96eb0d39b0c53f9346f ;)

some numbers jfyi:
70% LOC of the core are tab indented
47 files indent exclusively with space
129 files indent exclusively with tab
39 files have mixed indents

@alpe @fern4lvarez any preferences?

For Python or Ruby choice is easy, always spaces. For Java I tend to see tabs more convenient (same with Go, where there's no discussion at all thanks to gofmt), as more of our codebase is already using tabs. My opinion on this is not that strong and this document, which seems respectable, points to the spaces option though.

Ok, lets then go with tabs. Will update formatters.
