Problems with hyphenation and links
Dear FOP developers,
I sent a message to this list last week describing various problems
that I've encountered with FOP (look for "Probs with underline,
background, hyphenation, svg and more"). No-one has replied :-(
It would be really good to get someone's opinion, especially with
these two which I don't have a work-around for:
Hyphenation:
------------
Hyphenation works when there is more than one word in the block. If
there is only one word in the block, it is not hyphenated. I think it
should be. If I have one word in the block and the source has
whitespace before and after it, I get a run-time error. Here's the
example:
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master margin-right="25mm" margin-left="25mm"
margin-bottom="20mm" margin-top="15mm"
page-height="297mm" page-width="210mm"
master-name="a4">
<fo:region-before extent="10mm"/>
<fo:region-after extent="10mm"/>
<fo:region-body margin-bottom="15mm" margin-top="15mm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-name="a4">
<fo:flow flow-name="xsl-region-body">
<fo:block language="en" hyphenate="true">
Thisparagraphwillbehyphenated becauseithasmorethanonewordinit
andthisseemstoworkok. Theseverylongwords existonlysothat
thereisahighprobability thathyphenationwillberequired.
</fo:block>
<!-- Uncommenting this block gives "ERROR: null". This is identical to the
next block apart from white space before and after the single very-long
word.
<fo:block language="en" hyphenate="true">
ThisparagraphwillnotbehyphenatedbecauseitcontainsonlyoneextreemelylongwordandthisdoesnotseemtoworkIwasoriginallysufferingfromthisproblemintableswithnarrowcolumnsandwiththingslikeURLsthatareoftenverylongwithnospacesinthem.
</fo:block> -->
<!-- there should be no line breaks in the following; watch out if
they have been added "in the post". -->
<fo:block language="en" hyphenate="true">ThisparagraphwillnotbehyphenatedbecauseitcontainsonlyoneextreemelylongwordandthisdoesnotseemtoworkIwasoriginallysufferingfromthisproblemintableswithnarrowcolumnsandwiththingslikeURLsthatareoftenverylongwithnospacesinthem.</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
Links:
------
When I try this code, containing a basic-link and a break-before="page":
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master margin-right="25mm" margin-left="25mm"
margin-bottom="20mm" margin-top="15mm"
page-height="297mm" page-width="210mm"
master-name="a4">
<fo:region-body margin-bottom="15mm" margin-top="15mm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-name="a4">
<fo:flow flow-name="xsl-region-body">
<fo:block>
<fo:basic-link internal-destination="Y">
X
</fo:basic-link>
</fo:block>
<fo:block break-before="page"/>
<fo:block id="Y"/>
</fo:flow>
</fo:page-sequence>
</fo:root>
I get this output:
FOP 0.20.1
using SAX parser org.apache.xerces.parsers.SAXParser
building formatting object tree

[1] [2ERROR: The id "Y" already exists in this document
Any help very, very much appreciated.

Hi Keiron,
Many thanks for your reply.

Well I've downloaded 0.20.2 and tried my test code: the SVG and link
problems have both been fixed, which is great - thanks.
But I'm still getting run-time errors when I have hyphenation enabled
for blocks containing a single word. In my experiments I've also
uncovered an unpleasant interaction between hyphenation and
underlining: the part-word at the end of the line doesn't get
underlined.
The behaviour when I try to set the background colour for an inline or
make a block underlined also hasn't changed, i.e. they are still
ignored. Do you think this is the correct behaviour? Why?
Thanks for your time.
Regards,
--Phil.
Here is some code illustrating the problems that I'm still getting.
Remove the <!-- --> to see the run-time error.

Maybe everyone was inspired by your email address.
Most (if not all) of your problems have been fixed or don't appear to be
problems.
