- Parsing invalid JSON no longer asserts
Instead of asserting when coming across malformed JSON,
JsonParser::parse now returns an Optional<JsonValue>.
- Disallow trailing commas in JSON objects and arrays
- No longer parse 'undefined', as that is a purely JS thing
- No longer allow non-whitespace after anything consumed by the initial
parse() call. Examples of things that were valid and no longer are:
- undefineddfz
- {"foo": 1}abcd
- [1,2,3]4
- JsonObject.for_each_member now iterates in original insertion order
Our C++ code generator tools have been relying on host-side dbg() being
forwarded to stdout until now. Now they use out() instead.
Hopefully this will make it easier and more enticing to use streams in
userspace programs as well. :^)
FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.
When to use FlyString:
- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings
When not to use FlyString:
- For strings that don't need either of the above features
- For strings that are likely to be unique
