docbook-apps

Hi,

DocBook supports syntax highlighting in programlisting elements with
the help of the language attribute and the highlighting stylesheets
({fo,*html*}/highlight.xsl and highlighting/common.xsl). This works for
me.

Now I'm wondering if I can go it a bit further. Usually, customizing
the colors are done in xslthl mode. However, as it seems, I cannot get
the original language attribute anymore. I would like to implement
different colors for different programming languages.

How can I do that? Is there a recommended procedure?

Thanks!

Thomas, Publican [1] does this using the Kate HTML Syntax highlighting module.

I'm not sure whether this is the easiest solution but you can override
template apply-highlighting from highlighting/common.xsl in a way that
for each language special mode will be invoked instead of just
mode="xslthl", e.g.

<xsl:when test="function-available('s6hl:highlight') and $language =
'java'">
<xsl:apply-templates select="s6hl:highlight($language,
exsl:node-set($content), $highlight.xslthl.config)"
mode="xslthl-java"/>
</xsl:when>

<xsl:when test="function-available('s6hl:highlight') and $language =
'cpp'">
<xsl:apply-templates select="s6hl:highlight($language,
exsl:node-set($content), $highlight.xslthl.config)"
mode="xslthl-cpp"/>
</xsl:when>

Then you need to copy all templates with mode="xslthl" and change mode
to xslthl-java and xslthl-cpp and make appropriate changes.

For future we might pass optional parameter called language to all
templates in xslthl mode in order to for language in template for each
kind of keyword. If you think this will work better for your scenario,
please fill RFE.

Ahh, right. Thanks for the hint!

That would be a good idea. I've opened RFE#3608694.


Thanks to Jirka and Joshua!
