Custom YAML data types
|

======================
|

Often you will want to serialize complex data types such as classes. You can use

functions to process nodes; e.g. a mapping containing class data members indexed

by name. Alternatively, YAML supports custom data types using identifiers called

*tags*. That is the topic of this tutorial.

<dd><p>Specify tag directives.
|

</p>
|
||||
<p>A tag directive specifies a shorthand notation for specifying tags.
|
||||
Each tag directive associates a handle with a prefix. This allows for
|
||||
compact tag notation.
|
||||
<br>
|
||||
|
||||
Each handle specified MUST start and end with a '!' character
|
||||
(a single character "!" handle is allowed as well).
|
||||
<br>
|
||||
|
||||
Only alphanumeric characters, '-', and '_' may be used in handles.
|
||||
<br>
|
||||
|
||||
Each prefix MUST not be empty.
|
||||
<br>
|
||||
|
||||
The "!!" handle is used for default YAML tags with prefix
|
||||
"tag:yaml.org,2002:". This can be overridden.
|
||||
|
||||
</p>
|
||||
<b>Parameters:</b><div class="pbr"><table class=parms><tr><td valign=top>string[string] <b>tags</b></td>
|
||||
<td valign=top>Tag directives (keys are handles, values are prefixes).</td></tr>
|
||||
</table></div>
|
||||
<p><b>Example:</b><br>
|
||||
<pre class="d_code"> Dumper dumper = Dumper(<span class="d_string">"file.yaml"</span>);
|
||||
<span class="d_comment">//This will emit tags starting with "tag:long.org,2011"

<p>To compile your project, you must give DMD the directories containing import
