1) A new macro YAML_CPP_NORETURN to annotate functions as not returning in dll.h
2) A new function YAML_throw<ExceptionType>(args...) in exception.h
this function will throw an exception unless exceptions are disabled in the compiler,
detected by checking the pre-defined macro __cpp_exceptions
In this case the exception class will be instantiated, and the user-provided function
YAML::handle_exception(const char*) will be called on the exception's what() method
3) if exceptions are disabled,and the library's user does not provide YAML::handle_exception,
there will be a linker error
4) all other files have been changed automatedly by running the following sed commands
sed -i "s/throw \([A-Za-z]*\)(\(.*\))/YAML_throw<\1>(\2)/g" # throw statements for non-templated exceptions
sed -i "s/throw \(.*\)<\(.*\)>(/YAML_throw<\1<\2> >(/g" # throw statements for templated exceptions
* Removed an expression which is always true
* The second expression (ch is space) is removed because the first one contains space 0x20
* nextEmptyLine is always false so it is removed from the expression
This improves performance on the test.yaml attached to #158 by about
25% on my machine as compared to the previous commit (0.25s -> 0.20s),
as measured by `time build/util/parse < test.yaml > /dev/null`.
In particular:
1. Windows CR/LF weren't read properly (issue #11)
2. Scanning wasn't reading EOF properly
3. Documents may be empty (this was old, I think)
Also fixed some VS2008 warnings on /W4.
We were getting memory leaks (as told by the CRT detectors, which I also added), and there's really no reason (as long as we're careful) to use pointers there.
