call-seq: new()
:beautify
generate indented (beautiful) output. Default ‘false`.
:indent_string
Set an indent string which is used when yajl_gen_beautify
is enabled. Maybe something like \\t or some number of
spaces. The default is four spaces ' '.
:validate_utf8
Normally the generator does not validate that strings you
pass to it are valid UTF8. Enabling this option will cause
it to do so.
:escape_solidus
the forward solidus (slash or ‘/’ in human) is not required
to be escaped in json text. By default, YAJL will not escape
it in the iterest of saving bytes. Setting this flag will
cause YAJL to always escape '/' in generated JSON strings.
