Try running
 java -classpath ...fop.jar \
   org.apache.fop.layout.hyphenation.HyphenationTree
This class has a main function, which can be used for debugging
(check the source for details). You can use this to check whether
the problem is with the hyphenation librabry code and/or your
pattern definitions or whether it is in the code invoking the
hyphenator in the line layout.

"Odd numbers represent an acceptable location for a hyphen, with
higher values overriding lower inhibiting values. . .Due to a bug
currently patterns with values of 8 and greater don't have an effect,
so don't wonder." (from http://xml.apache.org/fop/hyphenation.html)

This leads me to believe that I should be using 7.  With 7 or with 1

Not necessarily... '7' indicates an acceptable possibility for hyphenating,
but as long as there's a possibility of breaking it at a '3', the latter
will be chosen.

Besides that:
F-R-A-P-P-L-E-S-,-R-O-B-E-R-T

is 15 characters, so I'd expect it to break between 'Robert' and '('.

What result do you get?

You have to add parenthesis and comma to the "classes" entry. And
you'll get a hyphen unless you redefined the hyphen character to

If you would have no file vi.xml and declare the language of the
vietnamese text parts to be 'vi', those parts should not be
hyphenated.

I'm a bit confused here... So, you are 'copying' the XML containing the
English hyphenation patterns to a new file 'vi.xml'? :-/
As I see it, this will have exactly the effect I described as 'using English
hyph patterns for Vietnamese text'. Unless the 'vi.xml' is made to contain
information specifically about hyphenation in Vietnamese, it's always going
to lead to undesired results.

All depends on where this attribute-set is used. If this set is in fact
being used on the Vietnamese parts, and hyphenation is still not disabled
for those blocks of text, this would be a bug.

If you were using two attribute-sets:


  en
  true

and

  vi
  false


The XSL should look like:


  



  


IIC, it would even be sufficient to only use the first set, and for the
Vietnamese parts, just omit the hyphenation properties.

Hope this helps!

Well... I see the document in question uses Vietnamese as well as English. I
suspect you have hyphenation turned on for all of the document (?) So most
likely, FOP is using English hyphenation patterns for the Vietnamese parts
as well?

If that is the case, I see two options:
- activate hyphenation for all of the document, and disable it
(hyphenate="false") for the Vietnamese parts
- activate hyphenation (hyphenate="true") only for the English parts

Hope this helps!

I'm not aware of any Java RTL class which reads the original

Charachter and Character.UnicodeBlock classes though, and
as of Unicode 4.0 the data seems to be stable enough that
outdated data isn't a problem (it never was for the vast
majority of the Java deveolpers). However, the line breaking
properties are not directly accessible, only through the
BreakIterator class. I think BIDI properties aren't directly

Somehow, the simple port of patgen as well as other attempts at
simplifying the current FOP hyphenator are missing, I hope I
remember to upload them tomorrow.
If someone want some problems to chew on:
- Implementation of an optimized trie or ternary or PATRICIA tree.
 Issues here: The FOP implementation packs both tree construction and
 retrieval into a single class, while the data structure is WORM.
 Furthermore, while it is fast, it could be implemented with much
 less memory, especially peak memory during construction. I ultimately
 concluded compiling the data into Java bytecode would be the best.
 Consider inserting the words WORD and WORM. A PATRICIA tree would
 collapse this to
   root: WOR -> leaf D
 -> leaf M
 In order to map this, the root node gets an operation "match string"
 with the string "WOR" leading to the subtree. Statistical compression
 could optimize the necessary operation, like "switch array", match
 2char string, match 3char string, match n-char string etc. May utilize
 BCEL.
- Institutionalized alphabet transformation. This is somewhat of a
 generalization of the hyphenation character classes. Java uses 16bit
 characters, but in many languages it is rare that more than 256
 characters are actually used in words. TeX/PatGen also map the
 characters onto the numbers 1..N (<256), folding character
 classification into the process. Mapping chars onto bytes saves almost
 half the memory. Because there are languages which requires more than
 256 characters, at least two implementation of the trie/whatever
 holding the patterns are necessary, one where the keys are byte
 sequences, another with char sequences. Too bad generics aren't ready
 yet, but if the data is byte compiled into a Java class, the compiler
 may analyze the patterns and decide whether bytes are sufficient.
 Stuff like Unicode character normalization should probably be folded
 into the classification/alphabet transformation too. It would be too
 bad if hyphenation failed because someone decided to use unnormalized
 characters like FI LIGATURE.
- API design. Need a hierarchy of interfaces which allow polymorphy
 at various levels:
  + Hyphenator
  implementations: pattern hyphenator, dictionary hyphenator,
  composite hyphenator: delegate to a collection of child
  hyphenators
  + Pattern hyphenator - pattern storage
 implementations: HashTable (very easy to understand but slow),
 R/W-trie, optimized WORM class, ...
  + Dictionary hyphenator - dictionary ...
 For reuse in interactive applications, R/W storage may be useful (user
 dictionaries)
- Generalized line breaking strategies. Possible strategies
 + naive, break before the first non-space after a space
 + TR14
 + break before any character
 + pattern, regexp or dictionary pased
- Other ideas: API for processing the Unicode data files. Optimized
 compile for Unicode properties into Java class data: select the
 properties you want, get it. Use this to get the latest Unicode data
 into your Java applications rather than the outdated stuff in the
 JRE.

participate? Do you know a nice name?
Regards, Simon
Sure! I'd love to participate! I don't know how yet, though...
Ideas for names? I guess it depends on how 'we' want to position this 
foundry. Is the foundry geared toward FOP users?

* fopstuff
* fop-stuff
* fostuff
* fo-stuff
* xslfostuff
* xsl-fo-stuff
* foptoys
* fop-toys
* fotoys
* fo-toys
* xslfotoys
* xsl-fo-toys
* fopaccessories
* fop-accessories
* foaccessories
* fo-accessories
* xslfoaccessories
* xsl-fo-accessories
* fopperipherals
* fop-peripherals
* foperipherals
* fo-peripherals
* xslfoperipherals
* xsl-fo-peripherals
I don't have a particular favorite, although since there are so many, 
it wouldn't be very helpful if I didn't 'choose' one or two. I like the 
ones *with* the hyphen (no pun intended! ;-) -- which makes it easier 
to read):

* xsl-fo-toys
* xsl-fo-stuff
In addition, since we want it to be of broader use (i.e., not just 
FOP), I would think we'd want to use one of the 'fo' or 'xsl-fo' 
prefixes (with or without hyphens) over the 'fop' based ones.

Hope this helps!

Even I've add to fop.jar the fr.hyp file.
Well, the hyphenator looks for a fr_fr.hyp file, probably because
you have both language="fr" and country="fr" defined. Either omit
the country, or rename the file, or just ignore the message.

You could simply exclude this word from hyphenation in the fo code like this:
some-word

As far as i understand the documentation at 
http://xml.apache.org/fop/hyphenation.html#patterns
there is no way to exclude words with characters in them that equal the hyphen 
character.

>From the documentation:
-
 contains whitespace-separated words, each of which has either 
explicit hyphen characters to denote acceptable breakage
points, or no hyphen characters, to indicate that this word should never be 
hyphenated, or contain explicit  elements for
specifying changes of spelling due to hyphenation (like backen -> bak-ken or 
Stoffarbe -> Stoff-farbe in the old german spelling).
Exceptions override the patterns described below. Explicit  declarations 
don't work yet (patches welcome). Exceptions are
generally a bit brittle, test carefully.
-

But if you replace the hyphen in the word with a similar looking character 
other than the hyphenation character, you should be able
to exclude this word from hyphenation generally by putting it into the 
 section of your hyphenation xml file as
described in the documentation.

Which character to use instead depends on the font you use. At least i think 
so. I do not know, which character is used for
hyphenation by default. In Arial for example there is a minus (U+002D) and a 
hyphen (U+2013). So if the hyphen is used for
hyphenation you could be able to use the minus for your special word, if these 
two characters are not treated the same (but that may
be the case). But this is only what i think. I don't have tried this or have 
any experience with that.
Just have a look into the character table for your font and you should find 
characters you might be able to use alternatively.

Maybe someone else can give some more hints on that.

Kind regards,
Roland

Re: Hyphenation on free text

From: Sherlane Lam <[EMAIL PROTECTED]>
Hi all,

I have made a sample.xml with a long free text as
shown in the attached document (sample3.xml) with
continuous character - 'AABBCCC..'
and so on.  I find that the appearance of the
characters become dis-order after the line breaking
(please find in the output.pdf).  I don't know whether
it is due to the xslt problem or fo problem.  Please
give me some suggestions.
I believe this behaviour was a bug in 0.20.4. Please upgrade to 0.20.5, as 
this problem should be fixed.

OK, it seems to work, thanks!

I have in this case some questions, but i fear they are not 100% FOP
related.

1. Further i were able to write the path to my True Types without drive

No "de" localization of "hyphenation-push-character-count" exists; using

...

But when FOP renders the FO-file there are no warnings and the generated
PDF has hyphenation.


3. The separator sign for hyphention in the preface is "#" and in the
chapters correct "-". I use DocBook with Stylesheet version 1.61.2.

then BUILD FOP yourself).

Good luck!

I will post my LineArea.java as soon as I have it cleaned up a bit. :-)
Here it is.
The problem concerning additional space is solved, too.

Re: Hyphenation

[Ralf Steppacher]

Is there a way to enforce TeX's behavior?
Not prepackaged. You are invited to hack around in the files
in layout/hyphenation.
OK, I did:
It is all in org.apache.fop.layout.LineArea.java. I altered the 
hyphenation strategie as follows:
If there is a hyphen in a word and the character data before the hyphen 
will fit into the current line, hyphenation will be done at the existing 
hyphen and nowhere else in the word.
If there is a hyphen but not enough space left do not hyphenate at all 
except for the case when this word is the first in a line (->the 
column/cell is not wide enough to hold the word in one piece).
In the latter case fall back to the standard hyphenation strategie.

There is also a bug (I think) in LineArea:
If the word to be hyphenated is the first in a line an additional space 
is put in front of it.
I tried to solve it by not assigning a 'space' as a spacer but a zero 
width space (\u200B) in this case. But I still end up with a visible 
space in the PDF document.

I will post my LineArea.java as soon as I have it cleaned up a bit. :-)

I don't think so.
