`snprintf()` will use the current `LC_NUMERIC` locale
for converting a double to a string,
which will use a `,` instead of a `.` in some locales (e.g. de_DE).
`std::stringstream` allows setting the locale to `"C"` to always get a `.`.
This occurs only for that `stringstream` instance; no global is
altered.
for (int index = 0; index < size && !isMultiLine; ++index)
In addition to dead code, in the above if condition checking to !isMultiLine is of no use as it will be always true and hence "for" depends only on condition [index < size.]
The mentioned test case works fine in this case also.
if (!isMultiLine) at line 563 suggests that isMultiline is 0 when if takes true branch. So the condition && at line 571 will always be false.
Also at line 568 !isMultiline in loop conditional check suggests that it depends only on one condition i.e. index <size because !isMultiline is always true.
Hence , it seems logical mistake at line 571 of using && instead of ||
This allows applications for interactively viewing or editing JSON to do
a better job of highlighting errors. Also added offset accessors to
Value, offering the same sort of functionality even for non-errors.
Thanks to Zach Clifford (zacharyc@google.com) for the patch.
This patch fixes some aspects of reading and writing comments:
- Multiple C++-style comments before a Json value had extra newlines appended to them. This patch removes the addition of those newlines.
- Comments written before Json values in the StyledWriter were not indented to match the indentation level of the value. This patch adds indentation to comments.
- Fixed inconsistency in newlines following C- and C++-style comments being saved as part of the comment. All newlines at the end of a comment are now removed.
- Added an additional test of comments.

The previous one was confusing and prone to buffer overflows, and didn't
work correctly with 16-decimal-digit numbers. The new one simply uses
snprintf with a standard format string.
The major change is that we don't always print a decimal point now.
Fortunately, JSON doesn't distinguish between integers and reals.
Most reasonable platforms have this function. If you're here because
this broke the build for you, consider adding an ifdef for your platform
and using sprintf there (but not on other platforms).
Igor Okulist and Damien Buhl (Patch #14). Added support for running
tests and building with DLL on Windows.
- added missing JSON_API
- 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.
- New header json/version.h now contains version number macros
(JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH
and JSONCPP_VERSION_HEXA). While this header is generated by CMake,
it is committed to ease build with alternate build system
(CMake only update the file when it changes avoid issues with VCS).
* isFoo methods determine exact representability.
* asFoo methods cause casting when safe.
* isConvertibleTo indicates whether casting is safe.
