<h2>API improvements</h2>
|
|
<ul class="simple">
|
|
<li><tt class="docutils literal">Loader</tt> is now, by default, constructed from a non-const buffer containing YAML
|
|
data instead of a <tt class="docutils literal">std.stream.Stream</tt>. D:YAML reuses and overwrites this buffer to
|
|
minimize memory allocations during parsing. Convenience API such as the <tt class="docutils literal">Loader</tt>
|
|
constructor from a filename is unchanged although it loads the file to a buffer
|
|
internally.</li>
|
|
<li><tt class="docutils literal">Node.contains()</tt> method to check if a YAML sequence/mapping contains specified
|
|
value (as opposed to a key).</li>
|
|
<li><tt class="docutils literal">Node.containsKey()</tt> method to check if a YAML mapping contains specified key.</li>
|
|
<li><tt class="docutils literal">Node.isNull()</tt> property.</li>
|
|
<li><tt class="docutils literal">Node operator in</tt> analogous to associative array <tt class="docutils literal">in</tt>.</li>
|
|
<li><tt class="docutils literal">Loader.fromString()</tt> method as a quick wrapper to parse YAML from a string.</li>
|
|
<li><tt class="docutils literal">dyaml.hacks</tt> module for potentially useful things YAML specification doesn't allow.</li>
|
|
<li>Most of the API is <tt class="docutils literal">@safe</tt> or at least <tt class="docutils literal">@trusted</tt>. Also <tt class="docutils literal">pure</tt> and <tt class="docutils literal">nothrow</tt>
|
|
where possible.</li>
|
|
<li>User-defined constructors can now also construct builtin YAML types.</li>
|
|
<li>Input is now validated at Loader construction to detect invalid UTF sequences early
|
|
and to minimize internal exception handling during parsing.</li>
|
|
</ul>
|
|
</div>
|
|
<div class="section" id="other-improvements">
|
|
<h2>Other improvements</h2>
|
|
<ul class="simple">
|
|
<li>D:YAML now works with a UTF-8 buffer internally. This decreases memory usage for UTF-8
|
|
input, and UTF-32 inputs can be encoded into UTF-8 in-place without allocating.
|
|
UTF-16 inputs still need an allocation. This also gets rid of all dchar[]->char[]
|
|
conversions which were a significant source of GC allocations.</li>
|
|
<li>Less GC usage during YAML node construction.</li>
|
|
<li>The <tt class="docutils literal">Scanner</tt> subsystems is now mostly <tt class="docutils literal">@nogc</tt>; it never allocates memory for
|
|
token values, using slices into the input buffer instead.</li>
|
|
<li>Custom, <tt class="docutils literal">@nogc</tt> UTF decoding/encoding code based on <tt class="docutils literal">std.utf</tt> to enable more use
|
|
of <tt class="docutils literal">@nogc</tt> in D:YAML internals and to improve performance.</li>
|
|
<li>Replaced <tt class="docutils literal">std.stream.EndianStream</tt> with custom endian-fixing code.</li>
|
|
<li>D:YAML is now a DUB package.</li>
|
|
<li>Removed static data structures such as default Constructor and Resolver.</li>
|
|
<li>Compile-time checks for size of data structures that should be small.</li>
|
|
<li>Better error messages.</li>
|
|
<li>Various refactoring changes, using more 'modern' D features, better tests.</li>
|
|
<li>Updated documentation, examples.</li>

|
<h2>Features/improvements</h2>
|
|
<ul class="simple">
|
|
<li><strong>API BREAKING</strong>: All structs and classes stored directly in YAML nodes
|
|
(aka custom YAML data types) now need to define the opCmp operator.
|
|
This is used for duplicate detection instead of AAs (which are broken)
|
|
and will allow efficient access to data in unordered maps.</li>
|
|
<li><strong>API BREAKING</strong>: Simplified the Constructor API. Constructor functions now
|
|
don't need to get Marks through parameters - any exceptions thrown by
|
|
the constructor functions are caught and wrapped along with Mark info.</li>
|
|
<li>Various small improvements in the API documentation.</li>
|
|
<li>Updated API documentation, tutorials and examples to match the changes.</li>
|
|
<li>Small CDC (build script) improvements.</li>
|

</ul>

<h2>Bugfixes</h2>

<ul class="simple">
|
|
<li>Fixed compilation with DMD 2.057.</li>
|
|
<li>Fixed a bug caused by std.regex changes that broke null value parsing.</li>

<div class="section" id="id5">
|
|
<h2>Features/improvements</h2>
|
|
<ul class="simple">
|
|
<li><strong>API BREAKING</strong>: Removed Node.getToVar as it turned out to be a premature
|
|
optimization.</li>
|
|
<li><strong>API BREAKING</strong>: Constructor API for constructing custom YAML data types has
|
|
been improved to make it easier to load custom classes/structs. See the
|
|
custom types tutorial and Constructor API documentation.</li>
|
|
<li>Node.opIndex now returns a reference to a node.</li>
|
|
<li>Added a shortcut alias Node.as for Node.get . Node.as might eventually
|
|
replace Node.get (in a 1.0 release).</li>
|
|
<li>User can now access a string representation of tag of a node.</li>
|
|
<li>Nodes now remember their scalar and collection styles between loading and
|
|
dumping. These are not accessible to user. User can set output styles in
|
|
Representer.</li>
|
|
<li>Updated API documentation to reflect the new changes, added more examples
|
|
and overall made the documentation more readable.</li>
|
|
<li>Improved error messages of exceptions.</li>
|
|
<li>Drastically optimized scanning and parsing, decreasing parsing time to about
|
|
10% (no precise benchmark comparison with 0.2 at the moment).</li>
|
|
<li>Eliminated most GC usage, improving speed and memory usage.</li>
|
|
<li>Optimized Dumper for speed, especially when dumping many small files.</li>
|
|
<li>Reader has been reimplemented to improve performance.</li>
|
|
<li>Many other speed and memory optimizations.</li>
|
|
<li>Added a profiling build target and a parsing/dumping benchmark.</li>
|
|
<li>Added a random YAML file generator and a YAML file analyzer, as example
|
|
applications and for benchmarking.</li>
|
|
<li>Added a "clean" target to example Makefiles.</li>
|
|
<li>Got rid of all global state.</li>

<h2>Features/improvements</h2>
|
|
<ul class="simple">
|
|
<li>Implemented YAML emitter, and related unittests/documentation.</li>
|
|
<li>Tags are now stored in nodes, allowing D:YAML to be closer to the
|
|
specification.</li>
|
|
<li>Loader API has been broken to make it more extensible in future -
|
|
Representer and Constructor are no more specified in the constructor,
|
|
and the load() shortcut functions have been removed, as all that's needed to
|
|
load a YAML document now is Loader("file.yaml").load() .</li>
