Description Tanja Roth 2011-07-18 12:58:51 UTC

When building our books with FOP, there is a huge amount of whitespace after each <ulink> or <filename> element by which the following text or punctuation is separated.

Example for <filename>: see https://bugzilla.novell.com/attachment.cgi?id=437718, p. 132, text below entry "meatware". 

Example for <ulink>: see https://bugzilla.novell.com/attachment.cgi?id=437718, p. viii.

Comment 1 Thomas Schraitle 2011-12-05 14:07:14 UTC

This is the affected line:

 | [...] cluster that it may consider the node dead. See /usr/share/doc/
 | packages/cluster-glue/README.meatware                      for more
 | information.

After some investigation, these are the current facts:

 * The URL is treated correctly and line break occurs after "/".
 * For some reason, "information" does not get hyphenated.

After the facts, here comes the speculations:
I guess, the hyphenation patterns for FOP (OFFO) are not installed. The whole guide seems to have no hyphenation at all (after browsing through it).

So it seems to me, this is more a FOP configuration bug rather than a FO stylesheet bug.

Comment 2 Thomas Schraitle 2011-12-05 14:20:46 UTC

It seems it is indeed a FOP configuration issue. I've added in etc/fop/fop-daps.xml the following line:

  <hyphenation-base>/usr/share/xmlgraphics-fop/hyph/</hyphenation-base>

This fixed this issue. I could successfully build one of our guides with hyphenation enabled.

Comment 3 Thomas Schraitle 2011-12-05 14:21:09 UTC

Resolved in revision 8039.

Comment 4 Thomas Schraitle 2012-02-03 14:51:35 UTC

It seems, FOP has some problems with Zero Width Spaces (ZWS, U+200B). If parameter 
ulink.hyphenate is set to "&#x200B;" the above effect in comment#1 will be printed.

For the time being, I disable ulink.hyphenate for FOP (leaving this bug as resolved/fixed).

Further information will be tracked in https://sourceforge.net/p/daps/tickets/33/
