breaking line rules
Hello,
How do you format a column so that it breaks ONLY on space. Currently, it seems to have many rules to break a text in a column. For example, it breaks on space, but it wouldn't start a new line of text with a period or comma. We want it always to break on space and only on space, no matter what.
Thank you,
Elena

Thank you very much for a great explanation. We figured out how to do it (we insert a line feed character ($C(10)), and the instruction in ZEN (we use ZEN to create pdfs) to break the line on line feed. That overwrites the rules below, and allows us to break on any character, depending on the width of the column.
Thanks again,
Elena

Hi Elena,
Disabling hyphenation will prevent words from being split. By the sounds of it though from your original message, you also want to break before punctuation marks? e.g.
[ Ideally ]
<-------------- Column Width --------------->
test . . . . . test , , , , , , test . . . . . test , , ,
, , test . . . . .
[ What will happen ]
<-------------- Column Width --------------->
test . . . . . test , , , , , , test . . . . .
test , , , , , test . . . . .
The above happens because the breaking algorithm checks a pair table against what it can and can't break against. Having a space and a punctuation mark is unbreakable therefore it looks for the next best break point and uses that one. There are two possible solutions which are either to modify the pair table (LineBreakUtils.java) called from LineBreakStatus.java(nextChar:84) in order to change how it treats certain pairs of characters. This would require a bit of debugging to see which values needs to be changed, though it's quite involved and not really recommended. Alternatively you can use force breaks by inserting 
 characters at certain points in the FO.
If I have misunderstood, it may be best if you provide a small example of the issue so we can have a clearer idea of what you are trying to do.
Regards,
Robert Meyer

Thank you so much for your response.
Does Hyphenate restricts only hyphen? Is it possible to break on width only? Is it possible to break on space only?
Thanks

Hi,
you just need to set the property "hyphenate" to "false".
