Re: [docbook-apps] Admon graphics: customizing spaces

["Bob Stayton" <bobs@sagehill.net>]

Unfortunately there is no way in XSLT to count the number of lines in tip.
The lines are formed by the XSL-FO processor after the stylesheet is done,
so the stylesheet has no information about how many lines a given tip
element will be.

You might want to study the rules of how spaces are combined in XSL-FO and
use combinations of space-after and space-before, and possibly
space-before.precedence and space-after.precedence.

Done.

Actually, after looking at the pdf production more in depth, I found
that this occurs only when the tip, note, etc. contains one and
unique line and not only inside a procedure.

I've styled the admonition outer-block as follows:

<!-- Style of admonitions -->
<xsl:attribute-set name="graphical.admonition.properties">
   <xsl:attribute name="space-before.minimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-before.optimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-before.maximum">0.3em</xsl:attribute>
   <xsl:attribute name="space-after.minimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-after.optimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-after.maximum">0.3em</xsl:attribute>
</xsl:attribute-set>

and normal para spacing as follows:

<!-- Normal paragraph spacing -->
<xsl:attribute-set name="normal.para.spacing">
    <xsl:attribute name="space-before.optimum">0.5em</xsl:attribute>
    <xsl:attribute name="space-before.minimum">0.5em</xsl:attribute>
    <xsl:attribute name="space-before.maximum">0.5em</xsl:attribute>
<xsl:attribute name="text-indent">0em</xsl:attribute>
</xsl:attribute-set>

Other paragraph space-before and space-after spacings vary from 0.8em
to 0.6em for sections.
List block space-before and space-after spacing are 0.4em, list item
space-before spacing 0.3em and compact list item space-before spacing
is 0em.

On the other way, I've defined the properties related to tip, notes,
etc as follows:

<!-- For figures, procedure, example, table -->
<xsl:attribute-set name="formal.object.properties">
   <xsl:attribute name="space-before.minimum">0.4em</xsl:attribute>
   <xsl:attribute name="space-before.optimum">0.4em</xsl:attribute>
   <xsl:attribute name="space-before.maximum">0.4em</xsl:attribute>
   <xsl:attribute name="space-after.minimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-after.optimum">0.3em</xsl:attribute>
   <xsl:attribute name="space-after.maximum">0.3em</xsl:attribute>
   <xsl:attribute name="keep-together.within-column">always</
xsl:attribute>
</xsl:attribute-set>

<!-- Style of title for procedure, example, table, figures
And space after procedure title -->
<xsl:attribute-set name="formal.title.properties">
   <xsl:attribute name="font-weight">bold</xsl:attribute>
   <xsl:attribute name="font-size">10pt</xsl:attribute>
   <xsl:attribute name="hyphenate">false</xsl:attribute>
   <xsl:attribute name="space-after.minimum">
     <xsl:choose>
       <xsl:when test="self::procedure">0em</xsl:when>
       <xsl:otherwise>inherit</xsl:otherwise>
     </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-after.optimum">
     <xsl:choose>
       <xsl:when test="self::procedure">0em</xsl:when>
       <xsl:otherwise>inherit</xsl:otherwise>
     </xsl:choose>
   </xsl:attribute>
   <xsl:attribute name="space-after.maximum">
     <xsl:choose>
       <xsl:when test="self::procedure">0em</xsl:when>
       <xsl:otherwise>inherit</xsl:otherwise>
     </xsl:choose>
   </xsl:attribute>
</xsl:attribute-set>


It seems that I need to count the number of lines of the tip text,
then if there is only one line, make the space after the tip graphics
a little more than 0em.

A little too complicated for me at the moment, i.e. I have no idea
how I can count the number of lines.
