We've talked about generating/parsing JSON a few times, and how we've
run into edge cases whenever we've rolled our own functions for that.
I've mentioned this C library a few times, but I'm not sure if I've
actually sent the link to anyone.. Here's a C library for
generating/parsing JSON, written by an ex-cow-orker of mine.
One feedback I've received earlier was that the "DOM-style"
architecture, where you build up the JSON object in-memory and then
dump it out, is not always a good match. If you want to avoid that,
you can pull off a trick like this pseudocode:
write("{")
json.dump(key)
write(":")
json.dump(value)
write(",")
json.dump(key2)
write(":")
json.dump(value2)
write("}")
The above still uses the library for proper string encoding etc, while
letting you control the top-level structure explicitly. And it should
be pretty easy to encapsulate the above in a convenience wrapper, to
make streaming even nicer; something like this pseudocode:
j = StreamingJSONObject(fd)
j.dump(key, value)
j.dump(key2, value2)
j.close()
