Problem with newlines in TextLayoutManager

Luca (and maybe Finn),

I think I found a problem with TextLayoutManager where NEWLINEs are not
properly handled. Consider the following block (extracted from list.fo):

          <fo:block line-height="10pt" space-before.optimum="5cm" 
            white-space-collapse="false" white-space-treatment="preserve" linefeed-treatment="preserve" wrap-option="no-wrap">
<![CDATA[<!-- list level 1 -->
<fo:list-block provisional-distance-between-starts="0.4cm"
               provisional-label-separation="0.15cm">

  <!-- list item -->
]]>
</fo:block>

If the FO file is parsed directly the SAX events happen to always start
with a NEWLINE and then adding exactly one line of text. In this case
the current algorithm finds the NEWLINE characters and adds the
necessary KnuthPenalty.

However, if you do an XSLT transform (as happens with my layout engine
test cases) the SAX characters() call can contain more than one line at
once. In this case the algorithm ignores the NEWLINEs (see comment). I
wonder why this was done like this. I think the whole linefeed handling
is done beforehand and all NEWLINEs still coming through this algorithm
are preserved linefeeds.

Is there some reason why my patch below would make anything worse? It
seems to fix my problem here and all my test cases still pass (at least
the ones that passed before).

Re: cvs commit: xml-fop/test/layoutengine/testcases normal-breaking2.xml

Just to be clear. This ArrayOutOfBoundsException is not the same problem
I've described in my earlier post. I just happened to run into both
problems at the same time. Running normal-breaking2.xml with the current
code (without my patch) will result in a document with 1 page and the
linefeeds displayed as "#". So, this test will fail because of the
single check in the test case.

If someone has an idea about the ArrayOutOfBoundsException, all the
better. I'm currently trying to debug that thing.

I'm not an expert on XML Schema and regular expressions, but shouldn't the "+" 
also be escaped, i.e. [\+\-]? If yes, don't bother to write a new patch. I'll 
do that for you, James.

FOP Bridge plug-in for FOP and Eclipse Integration

Hello Team FOP,

I wanted to let you know about a plugin for FOP integrates into Eclipse 3.x 
and allows users to render fo documents into any one of the many output 
formats supported by FOP, as well as TIFF, via the TIFF renderer component. 
I don't know if you would consider adding a link to the tool from the FOP 
website, as, to my knowledge, this is the first such tool that offers such 
integration.

http://www.ahmadsoft.org/fopbridge.html

thank you,
Amin Ahmad
