v0.4.0

Latest

Summary

This release adds new features: parsing multi-line plain scalars & reverse iterations over sequence/mapping node elements.
See the related pull requests and documentations for more details.

A number of bugs (mostly in the deserialization feature) have also been resolved.
Note that a breaking change has been made in the way of error handling when deserializing an int or float scalar fail. The library now emits no error on such a scalar and treats it as a string scalar instead.

What's Changed

💥 Breaking Changes

Stop throwing parse_error on string-to-int/float conversion failures if not forced with tag (#431, @fktn-k)
- reported by @tomwpid in the issue #428
- The library used to throw a fkyaml::parse_error upon conversion failures from a scalar to an integer or floating point value while parsing a YAML like this:
```
id: 6E-578 # "6E-578" is interpreted as a floating point value but not expressible as a `double`
           # --> `fkyaml::parse_error` gets thrown due to the conversion failure.
```
- Such a conversion failure is now internally recovered by treating the scalar as a string scalar instead.

✨ New Features

Support parsing multiline plain scalars (#432, @fktn-k)
- Parsing a YAML which contains multi-line plain (unquoted) scalars are now supported.
```
foo: this is 
  a multi-line
    plain scalar # interpreted as "this is a multi-line plain scalar"
```

Support reverse iterations over sequence/mapping nodes (#440, @fktn-k)

You can now iterate over sequence/mapping elements in a reversed order like this:

// node is [1, 2, 3]
for (auto rit = node.rbegin(); rit != node.rend(); ++rit) {
    std::cout << *rit << std::endl;
}

// output:
// 3
// 2
// 1

⚡ Improvements

Resolve the C4800 warning when compiled with MSVC (#430, @fktn-k)
- reported by tomwpid in the issue #429
Make node iterators compatible with different value type const-ness (#438, @fktn-k)
- fkyaml::node::iterator and fkyaml::node::const_iterator are compatible in constructions, assignments and comparisons.

fkYAML version 0.3.14

Summary

This release adds the new header file fkyaml_fwd.hpp which provides the library's namespace macros and forward declarations of the library's API classes. With the file, you can reduce the compile time cost of including the full library header if some source files do not actually use the library features.
Furthermore, conversions of YAML nodes into arbitrary types have been much improved and a lot more STL container and scalar types have been supported for that purpose. See the API documentation page for more details.
Other changes are related to minor bug fixes in YAML scalar parsing and maintenance fixes for CI.
