Hang on a sec... *squints*
Well you proved that I can't hand-parse that on the first attempt in my
head... OK, I fixed the thing. :)
Null-embedded string is OK if the "null" is spelled "\u0000".
I'm not sure about literal null bytes in the input. The spec says no
"control characters" are allowed in strings, but doesn't say what a
control character is. In any case, simplejson accepts literal nulls in
the obvious way.
You can't have octals or regexes.
So you end up with this:
{
"haha": "yeah, sure",
"for":3,
"you":"", "to": [ "parse",
"this", "I"
, "to", "parse", "this\n\"" ]
}
... which even I can parse!
>>> simplejson.load(file('test.txt'))
{u'to': [u'parse', u'this', u'I', u'to', u'parse', u'this\n"'], u'you':
u'', u'haha': u'yeah, sure', u'for': 3}
I think this actually makes your point better: JSON is a really simple
and well-specified language. Simplejson is 1034 lines total, and 371 of
those are the encoder.
p.s. I didn't realise that double-quotes were required around otherwise
syntactically valid identifiers...
I love the way that site uses railroad diagrams! :) Brings back memories.
