YAML serialization


The yaml vocabulary implements YAML serialization/deserialization. It uses LibYAML, a YAML parser and emitter written in C (http://pyyaml.org/wiki/LibYAML).

Main conversion words
>yaml ( obj -- str )

>yaml-docs ( seq -- str )

yaml> ( str -- obj )

yaml-docs> ( str -- arr )

Input
USING: prettyprint yaml ; "- true - null - ! 42 - \"42\" - 42 - 0x2A - 0o52 - 42.0 - 4.2e1" yaml> .
{ t f "42" "42" 42 42 42 42.0 42.0 }


Output -- human readable
