Subject: Improving JSON pretty printing, how to represent floats?
Date: Fri, 05 Apr 2024 11:39:10 +0200 [thread overview]
Message-ID: <87msq8w2zm.fsf@gmail.com> (raw)
Hi,
I'm thinking about using the new JSON parser and encoder for
json-pretty-print.
There is a thing that I don't like about the current
json-pretty-print: as it parses floats, pretty printing can be
lossy. If one pretty prints this
--8<---------------cut here---------------start------------->8---
{
"a": 3.333333333333000000000000000001
}
--8<---------------cut here---------------end--------------->8---
then the float gets rounded. I think pretty printing should be
lossless (keeping the exact format, exp notation, etc.).
What would be the best representation for numbers in this case?
I'm thinking about using symbols, but I'm not sure this is the
best approach. The parser/encoder would have a new keyword
parameter, like ":numbers-as-symbols t". If this is specified,
then numbers wouldn't be parsed, but kept as symbols. What do you
think, is this a good approach?
