Auto-generate caption for listings #19

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Captions are currently auto-generated for example, figure and table blocks. 
Numbering code listing blocks is a very common requirement for technical 
articles. Therefore, I think listing blocks should be added to the built-in set 
of blocks that get auto-numbered.

This requires a change to both the listingblock template and the 
source-highlight-block template (if in use).

The first step is to define a caption prefix in the language file:

[attributes]
listing-caption=Listing

The next step is to set the fallback caption in the listingblock in html 
backends. Here's the template for html5.conf.

[listingblock]
<div class="listingblock{role? {role}}{unbreakable-option? unbreakable}"{id? 
id="{id}"}>
<div class="title">{caption={listing-caption} {counter:listing-number}. 
}{title}</div>
<div class="content monospaced">
<pre>
|
</pre>
</div></div>

Here's the source-highlight-block template for the xhtml and html5 backends in 
source filter configuration file:

[source-highlight-block]
<div class="listingblock{role? {role}}">
<a name="{id}"></a>
<div class="title">{caption={listing-caption} {counter:listing-number}. 
}{title}</div>
<div class="content">
{source-highlighter$highlight:}<pre><code>
|
{source-highlighter$highlight:}</code></pre>
</div></div>
