Quotes usage for properties

[Daniel Mallorga]

Hi guys,

I was wondering whether it is the same to quote the property keys of a YAML properties file, or are there some specific cases where they should be quoted? I read somewhere, I can't remember now, that if there is a chance of a possible ambiguity, it is recommended to use quotes even for keys. I just wanted to know if, for SnakeYaml, this does it matter or not.

Thanks in advance,

Daniel.

Even when not using SnakeYaml, I’ve used strings containing blanks, ampersand&, exclamation! etc .. within the keys/LHS. 

Which obviously have to be quoted.

Worked great without fail everywhere (AWS, python too)

normally (when you do not an explicit tag) you use quotes (single or double) to mark a string scalar.

"2", '2" - these are strings

2 - this is a number
