This eases porting portable code and does not break compatibility with the previous release. Json::Value::asLargestInt() has also be added to ease writing portable code independent of 64 bits integer support. It is typically used to implement writers.

New in JsonCpp 0.6.0:
|
|
---------------------
|
|
|
|
* Compilation
|
|
|
|
- LD_LIBRARY_PATH and LIBRARY_PATH environment variables are now propagated to the build
|
|
environment as this is required for some compiler installation.
|
|
|
|
- Added support for Microsoft Visual Studio 2008 (bug #2930462):
|
|
The platform "msvc90" has been added.
|
|
|
|
Notes: you need to setup the environment by running vcvars32.bat
|
|
(e.g. MSVC 2008 command prompt in start menu) before running scons.
|
|
|
|
* Value
|
|
|
|
- Removed experimental ValueAllocator, it caused static
|
|
initialization/destruction order issues (bug #2934500).
|
|
The DefaultValueAllocator has been inlined in code.
|
|
|
|
- Added support for 64 bits integer:
|
|
|
|
Types Json::Int64 and Json::UInt64 have been added. They are aliased
|
|
to 64 bits integers on system that support them (based on __int64 on
|
|
Microsoft Visual Studio platform, and long long on other platforms).
|
|
|
|
Types Json::LargestInt and Json::LargestUInt have been added. They are
|
|
aliased to the largest integer type supported:
|
|
either Json::Int/Json::UInt or Json::Int64/Json::UInt64 respectively.
|
|
|
|
Json::Value::asInt() and Json::Value::asUInt() still returns plain
|
|
"int" based types, but asserts if an attempt is made to retrieve
|
|
a 64 bits value that can not represented as the return type.
|
|
|
|
Json::Value::asInt64() and Json::Value::asUInt64() have been added
|
|
to obtain the 64 bits integer value.
|
|
|
|
Json::Value::asLargestInt() and Json::Value::asLargestUInt() returns
|
|
the integer as a LargestInt/LargestUInt respectively. Those functions
|
|
functions are typically used when implementing writer.
|
|
|
|
The reader attempts to read number as 64 bits integer, and fall back
|
|
to reading a double if the number is not in the range of 64 bits
|
|
integer.
|
|
|
|
Warning: Json::Value::asInt() and Json::Value::asUInt() now returns
|
|
long long. This changes break code that was passing the return value
|
|
to *printf() function.
|
|
|
|
Support for 64 bits integer can be disabled by defining the macro
|
|
JSON_NO_INT64 (uncomment it in json/config.h for example), though
|
|
it should have no impact on existing usage.
|
|
|
|
- The type Json::ArrayIndex is used for indexes of a JSON value array. It
|
|
is an unsigned int (typically 32 bits).
|
|
|
|
- Array index can be passed as int to operator[], allowing use of literal:
|
|
Json::Value array;
|
|
array.append( 1234 );
|
|
int value = array[0].asInt(); // did not compile previously
|
|
|
|
- Added float Json::Value::asFloat() to obtain a floating point value as a
|
|
float (avoid lost of precision warning caused by used of asDouble()
|
|
to initialize a float).
|
|
|
|
* Tests
|
|
|
|
- Added test to ensure that the escape sequence "\/" is corrected handled
|
|
by the parser.
|
|
|
|
* License
|
|
|
|
- See file LICENSE for details. Basically JsonCpp is now licensed under
|
|
MIT license, or public domain if desired and recognized in your jurisdiction.

|
Thanks to Stephan G. Beal [http://wanderinghorse.net/home/stephan/]) who
|
|
helped figuring out the solution to the public domain issue.
