Re: Force a value:pair assignment to be string?

Kenneth,

short answer:
  You should be able quote those Y/N items to force them 
  to be a string.

long answer:
  You might be able to configure your parser to not "implicitly
  type" Y/N as a boolean value.  

longest answer: >
  You've hit the #1 usability prooblem with YAML, it's called "implicit
  type resolution" and different implementations are doing it
  differently.  
  
  The original goal was to make it easy to type in integers and have
  them show up as integers w/o littering your text with "!!int".
  Unfortuntely, where that line should be drawn is a bit hard.

  In the next pass of YAML, I am going to recommend that all parsers
  _only_ do implicit typing on:
  
    (a) symbolic values, such as <<, which can be used to 
        augment the YAML syntax /w very nice hooks
        
    (b) numbers, "true" "false" and "null", following
        the JSON standard (for compatibility)

  At least, this should, IMHO, be the default.  I think Ingy begs
  to differ and believes the default should be *all strings* with
  no implicit typing.  What ever we come up with, getting there 
  is sure to be unpleasent; but probably far less unpleasant than
  the current state of affairs.

Cheers,

Clark
