The CBOR and MessagePack parsers now expect the input to be read until the end. Unless the new parameter "strict" is set to false (it is true by default), an exception is raised if the parser ends prematurely. This is a breaking change as the parsers ignored unread input so far.
Furthermore, the offset/startIndex paramter introduced in #462 was removed as this behavior can be mimicked with an iterator range. For instance, instead of calling "from_cbor(vec, 5);", you can write "from_cbor({vec.begin()+5, vec.end()});".
o To prevent the compilation issue on OSX with the intel compiler suite. The
error was found with icpc version 15.0.3.187 where the "__clang_version__" was
not defined correctly, while "__clang__" was.
- replaced list of pairs by flat list in next_byte_in_range
- implemented early exit in case of parse errors
- reused memory for object keys
- direct calls to embedded objects/arrays for insertions
You can now pass a boolean "allow_exceptions" to the parse functions. If it is false, no exceptions are thrown in case of a parse error. Instead, parsing is stopped at the first error and a JSON value of type "discarded" (check with is_discarded()) is returned.
On MSVC compiler, temporaries that are constructed during a
list initialization, are sometimes destroyed even before calling
the initializing constructor, instead of at the end of the
containing full-expression. This is clearly non-conforming to
[class.temporary].
As the impact of this bug is silently producing incorrect
JSON values, move eagerly from rvalues to be safe.

- You can now pass a reference to a vector to the to_cbor and to_msgpack functions. The output will be written (appended) to the vector. #476
- You can now pass an output stream with uint8_t character type to the to_cbor and to_msgpack functions. #477
- You can now read from uint8_t */size in the to_cbor and to_msgpack functions. An input adapter will be created from this pair, so you need to use braces. #478
This commit works around an issue in std::initializer_list design.
By using a detail::json_ref proxy with a mutable value inside,
rvalue-ness of an input to list initializer is remembered and
used later to move from the proxy instead of copying.
Travis found an error with Clang 3.8's sanitizers, see https://travis-ci.org/nlohmann/json/jobs/256366699. Unfortunately, I cannot reproduce this error with clang version 6.0.0 (trunk 308825) locally. However, this seems to be an issue, because so far, we did not reset a value after moving from it.
A complete rewrite of the string escape function. It now provides codepoint-to-\uxxxx escaping. Invalid UTF-8 byte sequences are not escaped, but copied as-is. I haven’t spent much time optimizing the code - but the library now agrees with Python on every single Unicode character’s escaping (see file test/data/json_nlohmann_tests/all_unicode_ascii.json).
Other minor changes: replaced "size_t" by "std::size_t"
It makes no sense to have this special exception. Instead of throwing when an input adapter is created, it is better to detect a parse error in later usage when an EOF is "read" unexpectedly.
These breaks were just added to silence a GCC warning - the GCC is right about warning as it cannot know that the expect function will not return in these two scenarios.
It seems these functions are not required any more. The code was added in commit 7e32457 to fix issue #171. There are still regression tests for #171, so when this commit passes the CI, the functions may be removed for good.
When an empty vector was passed to the parse function, an empty iterator range was used to construct an input iterator. Unfortunately, we then cannot use the start iterator to derive a pointer from.
Found with Xcode's undefined behavior sanitizer.
