Konrad Windszus commented on DOXIA-764:
---------------------------------------
The {{<pre>}} element has special semantics
{quote}
In the HTML syntax, a leading newline character immediately following the pre
element start tag is stripped.
{quote}
(https://html.spec.whatwg.org/multipage/grouping-content.html#the-pre-element)
This used to kick in prior DOXIA-731, but afterwards no longer. Therefore
leading newlines should be removed manually by the Xhtml5BaseSink to imitate
the pre DOXIA-731 newline behaviour.
> XDoc source has a spurious new line at the beginning

> Key: DOXIA-764
> URL: https://issues.apache.org/jira/browse/DOXIA-764
> Project: Maven Doxia
> Issue Type: Bug
> Components: Module - Xdoc
> Affects Versions: 2.0.0
> Reporter: Konrad Windszus
> Assignee: Konrad Windszus
> Priority: Major
>
> HTML rendered from the following XDoc snippet
> {code}
> <source>
> sink.paragraph();
> sink.text( "my text" );
> sink.paragraph_(); </source>
> {code}
> has a spurious new line at the beginning when rendered as HTML:
> {code}
> <pre class="prettyprint linenums"><code>
> sink.paragraph();
> sink.text( "my text" );
> sink.paragraph_(); </code></pre>
> {code}
> Probably a regression of DOXIA-731.
> Previously this was converted to
> {code}
> <div class="source"><pre class="prettyprint linenums">
> sink.paragraph();
> sink.text( "my text" );
> sink.paragraph_(); </pre></div>
> {code}
> where the first linebreak inside {{pre}} was ignored as it is a block element.
