FOP: force wordbreak

Rate this Message:
Hi,
I'm having a problem with wordbreaking correctly. The "word" is in this case a link url shown as text. The structure of it is like: <fo:basic-link external-destination"http://www.thisismyveryverylonglink.com/longlink">http://www.thisismyveryverylonglink.com/longlink</fo:basic-link> The link is placed in a table and sometimes it happens, that it doesnt break correctly. In most cases the link breaks after every last "/" in this case the output is ( # marks the tableborder): http://thisismaverylonglink.com/ # longlink But if the last slash is placed under 50% of the tablecellwidth it doesn't break: http://shortprename/longlonglongl#onglonglonglonglongtail Also do links exists like: http://www.xyz.com/ longlonglonglonglonglonglonglonglo#nglonglonglonglonglonglonglonglonglonglongtail I need a solution which breaks the link at the end of the tablecell and goes on next line, i don't need hyphenation rules like after "/" or something. Any ideas for that problem? Greetings JPee |

Hi JPee,
Probably the only thing you can do is insert zero-width spaces.

Thanks for your quick advise,
is there a way to get the position of the character where the line break should be? Greetings JPee |

Hi JPee,
I guess that depends on where the line break should be. A zws after each / is easy: Replace "/" with "/zws". A zws after every x characters should be possible through application of substring. But I don't know all the XSL string manipulation methods, so there might be smarter solutions. Maybe regex: After x characters which do not contain a zws, insert a zws.

My current solution is with substring and works fine but is not the best solution for my case, because characters have different lengths. Example:
iiiii eeeee both lines have 5 chars but have different lengths and if a link has 3 lines it looks not that good as possible. What I need is a method which gives the position where to enter the break. Greetings JPee

Hi JPee,
No luck there. The actual character width depends on the font used, which is available for fop, but not at the xslt stage. If you really need a break at any place, put a zws after each character.

Hi Chris,
I was afraid the specification was to blame. One could implement an extension, put it on flow, maybe even page-sequence and make it inheritable. So it would not break existing code.

So it would not break existing code. That would be quite easy. Only I don't know how much work the changes in the actual line-breaking algorithmus would be. See following bug report for a discussion of the issue: https://issues.apache.org/bugzilla/show_bug.cgi?id=43474 As a summary: I don’t think anything should be done in FOP. This issue is better handled upstream (usually by inserting zero-width spaces “at the right places”, which sometimes can be properly done only by a human being). If the URL doesn’t fit in a table cell, then don’t put it in a table. Or increase the width of the table cell accordingly. URL quickly become unreadable when they are broken anyway.

Hi Vincent,
I just read the bug report discussion. Most points I either agree with you or don't know enough to disagree (the relevance of 'script', for example). So, FOP is essentially correct and shouldn't change its default behaviour. Only an extension could help. > > More seriously, you could take it the other way around, and find users who > > wouldn't be happy at all to see FOP suddenly break their texts at arbitrary > > places, and would rather be warned when such situations are occuring, so that > > they can re-work their contents. From my experience, an overflow warning by itself hardly helps. During development I get PAGES of overflow warnings. 99% of them are, while not nice, ignoreable. I can't test every possible data combination. So sometimes the user might get an overflow. The debug output is not transfered to the user, only the finished PDF is. And here (for me) it's far easier to notice an additional line with only one letter than a full line with the last letter overwriting the first letter of the next cell. Yes, an upstream solution would be better, but we are talking about cases, where the only upstream solution would be a zws between each two characters. I don't know if anybody analyzed the content-to-markup-ratio of fo-files before, but I have fo-files of 220MB, let's assume 10% is real text, so I'd insert 20 million zws and actually need maybe two of them.

One could implement an extension, put it on flow, maybe even page-sequence and make it inheritable. So it would not break existing code. That would be quite easy. Only I don't know how much work the changes in the actual line-breaking algorithmus would be. See following bug report for a discussion of the issue: https://issues.apache.org/bugzilla/show_bug.cgi?id=43474 As a summary: I don't think anything should be done in FOP. This issue is better handled upstream (usually by inserting zero-width spaces "at the right places", which sometimes can be properly done only by a human being). If the URL doesn't fit in a table cell, then don't put it in a table. Or increase the width of the table cell accordingly. URL quickly become unreadable when they are broken anyway.

If FOP doesn't find a break possibility, the text is printed outside of the area. In table cells, the text is printed into the next cell. Does anybody need this? Wouldn't it be better to break anyway if the outer areas ipd is reached? And if I WANT to write into the next cell, I could always use keep-together.within-line="always"... > > or wrap-option="no-wrap" > > I think the reason this is not done as you suggest is because the specification mandates the current behaviour. However, I concur with you. It would be more beneficial if the behaviour was user friendly and either wrapped or not the text based on the wrap-option property. > > Thanks, > > Chris > >> Regards, >> >> Georg Datterl >> >> ------ Kontakt ------ >> >> Georg Datterl >> >> Geneon media solutions gmbh >> Gutenstetter Straße 8a >> 90449 Nürnberg >> >> HRB Nürnberg: 17193 >> Geschäftsführer: Yong-Harry Steiert >> >> Tel.: 0911/36 78 88 - 26 >> Fax: 0911/36 78 88 - 20 >> >> www.geneon.de >> >> Weitere Mitglieder der Willmy MediaGroup: >> >> IRS Integrated Realization Services GmbH: www.irs-nbg.de >> Willmy PrintMedia GmbH: www.willmy.de >> Willmy Consult & Content GmbH: www.willmycc.de >> -----Ursprüngliche Nachricht----- >> Von: J.Pietschmann [mailto:j3322ptm@...] >> Gesendet: Montag, 5.
