BreakingAlgorithm Problem
Hi!
I use FOP 0.93 and write some data in a table with several columns. In one
column data can be broader than the column-width without any chance to
hyphenate.
FOP then logs message: "WARN [BreakingAlgorithm] Line 1 of a paragraph
overflows the available area."
I tried to get rid of it with overflow- and wrap-option-attributes, but it
doesn'nt work:
<fo:table-cell>
<fo:block-container overflow="scroll" wrap-option="wrap">
<fo:block language="de" hyphenate="true()">
<xsl:value-of select="."/>
</fo:block>
</fo:block-container>
</fo:table-cell>
Say, I have a string "www.verylonguri.com", FOP can't hyphenate it and does
write it into the next column. I would like to break it hard, like this:
www.verlon
guri.com
Is there any way to archive this?
Thank you in advance!
Franz

In addition 0.94 should break at the '/' character automatically, i.e.
it should break typical URLs. However, it will not break on '.' not
followed by whitespace (if it did if could have very unfortunate
effects on numbers like $12.50).

Yes, this was a bug in 0.93 IIRC. Upgrading to 0.94 should resolve
the issue.
HTH!

Hi Kumar,
thanks for your hint. I wrote a template, which checks if there are some
non-letter-characters (like '.', '/'; etc.). If this is the case, I concat
the string after each character with Unicode Zero Width Space('​'),
but then FOP 0.93 overlaps letters. I also tried FIGURE SPACE ('&x#2007;'),
but then FOP does break it half way ... very strange. Here my code snippet:
<xsl:variable name="sNew">
<xsl:for-each select="0 to string-length($s)">
<xsl:value-of select="concat(substring($s,.,1), '​')"/>
</xsl:for-each>
</xsl:variable>
<xsl:copy-of select="$sNew"/>
Any idea, why FOP0.93 is doing it that way?
Thanks in advance,
Franz

You could insert a Unicode Zero Width Space (​) after each
character within your table-cell. That should enable the word to break
properly without overflowing into the next cell.
However, if the same logic is applied to some standard text (which can
hyphenate) it will no longer hyphenate.
Thanks,
Kumar
