Re: [docbook-apps] aligning code to the right

This is actually difficult to do inside a programlisting. The problem is that a programlisting is handled as a single string containing white space and line breaks that are preserved by the formatter.  But neither XSL-FO or CSS provide a way to change the alignment of an inline string, even when it is bounded by line feeds on both sides. 

 

To effect a change of alignment, the long string would need to be broken and "text to the right" would need to be placed inside an fo:block (or div for HTML) so that the text-align="right" formatting property could be applied.  But when you put that text in its own fo:block, that breaks the line before and after.  Those line breaks add to the line breaks already existing in the text string, so you get a blank line before and after from the double line breaks.

 

The only solution I can see is to remove the line breaks in the source file programlisting before and after such text, and wrap the text in <phrase role="right-align"> like this:

 

<programlisting>First line<phrase role="right-align">text to the right</phrase>Third line

And more lines.

</programlisting>

 

and add this template to your customization layer:

 

<xsl:template match="phrase[@role='right-align']">
  <fo:block text-align="end">
    <xsl:apply-templates/>
  </fo:block>
</xsl:template>

 

And something similar using <div> for HTML output.  This should result in:

 

-------------------------------------------------------------------

First line

                                                  text to the right

Third line

And more lines
--------------------------------------------------------------------

 

Removing the line breaks in the programlisting makes it difficult to read, but it does work.
