- Don't eagerly convert key to std::string
- Make const char* keys streamable when exception is thrown
- Don't create a temporary string when comparing a const char* key
Invalid access via operator[] or as<> will now print the offending key, if possible.
For example:
a:
x: 1
y: 2
node["a"]["z"].as<int>()
will say that the key "z" was invalid.
* Add compilation flags: -Wshadow -Weffc++ -pedantic -pedantic-errors
* Delete implicit copy & move constructors & assignment operators
in classes with pointer data members.
* An exception to the above: Add default copy & move constructors &
assignment operators for the Binary class.
* Convert boolean RegEx operators to binary operators.
* Initialize all members in all classes in ctors.
* Let default ctor delegate to the converting ctor in
Binary and RegEx
* Don't change any tests except regex_test (as a result of the change
to binary operators).
Note: https://bugzilla.redhat.com/show_bug.cgi?id=1544675 makes
-Weffc++ report a false positive in "include/yaml-cpp/node/impl.h".
"const Node Node::operator[](const Key& key) const" changed from
returning new empty node if the key was missing in 0.5.1 to returning
a shared 'zombie' node in 0.5.2 to resolve a memory leak.
(Specifically 1025f76df1 was where this
was introduced)
This caused some regressions where this 'zombie' object threw exceptions
in some functions where the 'empty' object would not.
This change fixes the Node::as(fallback) method (to return the
'fallback' instead of throwing an exception) and the
Node::begin()/Node::end() methods to return default-constructed
iterators (so begin() == end() in such cases) instead of another
exception.
