-New in SVN
-----------
-
- * Updated the type system's behavior, in order to better support backwards
- compatibility with code that was written before 64-bit integer support was
- introduced. Here's how it works now:
-
- * isInt, isInt64, isUInt, and isUInt64 return true if and only if the
- value can be exactly represented as that type. In particular, a value
- constructed with a double like 17.0 will now return true for all of
- these methods.
-
- * isDouble and isFloat now return true for all numeric values, since all
- numeric values can be converted to a double or float without
- truncation. Note however that the conversion may not be exact -- for
- example, doubles cannot exactly represent all integers above 2^53 + 1.
-
- * isBool, isNull, isString, isArray, and isObject now return true if and
- only if the value is of that type.
-
- * isConvertibleTo(fooValue) indicates that it is safe to call asFoo.
- (For each type foo, isFoo always implies isConvertibleTo(fooValue).)
- asFoo returns an approximate or exact representation as appropriate.
- For example, a double value may be truncated when asInt is called.
-
- * For backwards compatibility with old code, isConvertibleTo(intValue)
- may return false even if type() == intValue. This is because the value
- may have been constructed with a 64-bit integer larger than maxInt,
- and calling asInt() would cause an exception. If you're writing new
- code, use isInt64 to find out whether the value is exactly
- representable using an Int64, or asDouble() combined with minInt64 and
- maxInt64 to figure out whether it is approximately representable.
-
-* Value
- - Patch #10: BOOST_FOREACH compatibility. Made Json::iterator more
- standard compliant, added missing iterator_category and value_type
- typedefs (contribued by Robert A. Iannucci).
-
-* Compilation
-
- - New CMake based build system. Based in part on contribution from
- Igor Okulist and Damien Buhl (Patch #14).
-
- - New header json/version.h now contains version number macros
- (JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH
- and JSONCPP_VERSION_HEXA).
-
- - Patch #11: added missing JSON_API on some classes causing link issues
- when building as a dynamic library on Windows
- (contributed by Francis Bolduc).
-
- - Visual Studio DLL: suppressed warning "C4251: <data member>: <type>
- needs to have dll-interface to be used by..." via pragma push/pop
- in json-cpp headers.
-
- - Added Travis CI intregration: https://travis-ci.org/blep/jsoncpp-mirror
-
-* Bug fixes
- - Patch #15: Copy constructor does not initialize allocated_ for stringValue
- (contributed by rmongia).
-
- - Patch #16: Missing field copy in Json::Value::iterator causing infinite
- loop when using experimental internal map (#define JSON_VALUE_USE_INTERNAL_MAP)
- (contributed by Ming-Lin Kao).
-
-
- 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.
-
- - Added support for amalgamated source and header generation (a la sqlite).
- Refer to README.md section "Generating amalgamated source and header"
- for detail.
-
-* 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).
-
-* Reader
-
- - Renamed Reader::getFormatedErrorMessages() to getFormattedErrorMessages.
- Bug #3023708 (Formatted has 2 't'). The old member function is deprecated
- but still present for backward compatibility.
-
-* Tests
-
- - Added test to ensure that the escape sequence "\/" is corrected handled
- by the parser.
-
-* Bug fixes
-
- - Bug #3139677: JSON [1 2 3] was incorrectly parsed as [1, 3]. Error is now
- correctly detected.
-
- - Bug #3139678: stack buffer overflow when parsing a double with a
- length of 32 characters.
-
- - Fixed Value::operator <= implementation (had the semantic of operator >=).
- Found when adding unit tests for comparison operators.
-
- - Value::compare() is now const and has an actual implementation with
- unit tests.
-
- - Bug #2407932: strpbrk() can fail for NULL pointer.
-
- - Bug #3306345: Fixed minor typo in Path::resolve().
-
- - Bug #3314841/#3306896: errors in amalgamate.py
-
- - Fixed some Coverity warnings and line-endings.
-
-* 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.
