Hi, I’m trying YAML with Ruby and it allows TAB for indentation, but it  
seems  
that it shouldn’t be allowed (at least Wikipedia says that).

Is then TAB allowed or not for indentation in YAML format?  
Maybe Ruby YAML allows it but it shouldn’t do it?

Thanks a lot.

Cant give a definite answer on it but If i need to write rather freely  
in yaml I normally do:

entry: |  
"some really long  
string coming here… describing something etc… "

No, it isn’t allowed in Ruby YAML too.

Sorry, my mistake. Ruby YAML doesn’t allow TAB for indentation.  
Fucking VI that converts TAB to spaces XDDD
