<!-- Generated by Ddoc from dyaml/loader.d -->
|

<p>Class used to load YAML documents.</p>
|
|
|
|
<dl><dt class="d_decl"><a name="Loader"></a>struct <a name="Loader"></a><span class="ddoc_psymbol">Loader</span>;
|
|
</dt>
|
|
<dd><p>Loads YAML documents from files or streams.
|
|
</p>
|
|
<p>User specified Constructor and/or Resolver can be used to support new
|
|
tags / data types.
|
|
|
|
</p>
|
|
<b>Examples:</b><div class="pbr">Load single YAML document from a file:
|
|
<pre class="d_code"><span class="d_keyword">auto</span> rootNode = <span class="d_psymbol">Loader</span>(<span class="d_string">"file.yaml"</span>).load();
|
|
...
|
|
</pre>
|
|
<br>
|
|
|
|
Load all YAML documents from a file:
|
|
<pre class="d_code"><span class="d_keyword">auto</span> nodes = <span class="d_psymbol">Loader</span>(<span class="d_string">"file.yaml"</span>).loadAll();
|
|
...
|
|
</pre>
|
|
<br>
|
|
|
|
Iterate over YAML documents in a file, lazily loading them:
|
|
<pre class="d_code"><span class="d_keyword">auto</span> loader = <span class="d_psymbol">Loader</span>(<span class="d_string">"file.yaml"</span>);
|
|
|
|
<span class="d_keyword">foreach</span>(<span class="d_keyword">ref</span> node; loader)
|
|
{
|
|
...
|
|
}
|
|
</pre>
|
|
<br>
|
|
|
|
Load YAML from memory:
|
|
<pre class="d_code"><span class="d_keyword">import</span> std.stream;
|
|
<span class="d_keyword">import</span> std.stdio;
|
|
|
|
string yaml_input = <span class="d_string">"red: '#ff0000'\n"</span>
|
|
<span class="d_string">"green: '#00ff00'\n"</span>
|
|
<span class="d_string">"blue: '#0000ff'"</span>;
|
|
|
|
<span class="d_keyword">auto</span> colors = <span class="d_psymbol">Loader</span>.fromString(yaml_input).load();
|
|
|
|
<span class="d_keyword">foreach</span>(string color, string value; colors)
|
|
{
|
|
writeln(color, <span class="d_string">" is "</span>, value, <span class="d_string">" in HTML/CSS"</span>);
|
|
}
|
|
</pre>
|
|
<br>
|
|
|
|
Use a custom constructor/resolver to support custom data types and/or implicit tags:
|
|
<pre class="d_code"><span class="d_keyword">auto</span> constructor = <span class="d_keyword">new</span> Constructor();
|
|
<span class="d_keyword">auto</span> resolver = <span class="d_keyword">new</span> Resolver();
|
|
|
|
<span class="d_comment">//Add constructor functions / resolver expressions here...
|
|
</span>
|
|
<span class="d_keyword">auto</span> loader = <span class="d_psymbol">Loader</span>(<span class="d_string">"file.yaml"</span>);
|
|
loader.constructor = constructor;
|
|
loader.resolver = resolver;
|
|
<span class="d_keyword">auto</span> rootNode = loader.load(node);
|
|
</pre>
