Subject: Re: [docbook-apps] Zero-width space as line-wrapping workaround?
Hi Thomas,Thanks for advising, and for the hyphenate-url.xsl template! Minor question below.

Personally, I don't like invisible things like this that could get in the way of grepping through the source. Any other pros and cons? Maybe other/better ways to work around the problem?I had the same concerns with grepping through the sources. For URLs, the solution is very easy. Use the following two parameters: * $ulink.hyphenate Set it to the ZERO WIDTH SPACE character (​ or ​). By default, it is empty. * $ulink.hyphenate.chars Defines which characters are considered to contain the ZWS after that character. By default, it's "/", but you could extend it with other characters like "_", "-", "&", ... These two parameters are used in the "hyphenate-url" template. This template goes through the string and checks each character, if it's in the set of $ulink.hyphenate.chars. You could use this template as a base for your <option> template.
Any experience with performance impacts? I'm asking because we have quite a few options that would get parsed:
~/svn/mysqldoc> grep -R "<option" | wc -l 65219
You can find an example of my modification of hyphenate-url in the daps repository. I needed a finer control which characters should contain the ZWS before or after that character. You can find the code here: https://svn.code.sf.net/p/daps/svn/trunk/daps/suse/xslt/fo/hyphenate-url.xsl Hope this helps. :)
Sure, thanks again! -- Cheers, Stefan Hinz <email@example.com>, MySQL Documentation Manager Phone: +49-30-82702940, Fax: +49-30-82702941, http://dev.mysql.com/doc ORACLE Deutschland B.V.& Co.
