This change make safe for `char = signed char`.
As the spec, argment of `isprintf()` must be representabe as an
`unsigned char` (or equal to EOF, not expected here).
Additionally, some implementation define it as a macro using array,
then it cause warning "array subscript has type `char` [-Wchar-subscripts]"
with `char` argments.
msgpack_object_print used fwrite to write binary data to a stream. The intention
of the function is to produce a human-readable representation of the object for
debugging purposes. Having arbitrary data dumped as is can cause issues with
terminals that interpret it as control sequences.
This change prints printable characters as is and unprintable characters as
hex-escapes ("\xNN"). Note that UTF-8 encoded characters will now be printed as
escaped sequence of UTF-8 bytes. This is an acceptable compromise, as doing
otherwise would require a light form of UTF-8 decoding and BIN-typed objects
should not be used to transport UTF-8 strings anyway (STR should be used
instead).
The names of float format family are changed.
old new
dec -> f64
MSGPACK_OBJECT_DOUBLE -> MSGPACK_OBJECT_FLOAT
msgpack::type::DOUBLE -> msgpack::type::FLOAT
Client codes could have compile errors when it use dec, MSGPACK_OBJECT_DOUBLE or msgpack::type::DOUBLE.
The best way to fix such errors, update client code. If it can't, set MSGPACK_USE_LEGACY_NAME_AS_FLOAT macro.
Then both old names and new names are available.
Fixed inttypes.h inclusion problem on MSVC.
Fixed msgpack_object_print implementation using PRIi8, PRIi64, and PRIu64.
If 64bit print is not supported on fprintf, dispatch to fallback print.
