Custom breakpoints for \hyphenatedurl

Custom breakpoints for \hyphenatedurl

[Joshua Krämer]

Dear list,

I could successfully configure ConTeXt to introduce linebreaks /after/
some characters in URLs with \sethyphenatedurlafter {...}

I would also like to disable linebreaks /before/ some of the predefined
characters.  For example, no linebreak should occur before :

Is this possible?  \sethyphenatedurlbefore {} (with empty braces)
does not work.

Unfortunately, usage of \sethyphenatedurlafter also introduced the
following problem:  the \hyphenatedurlseparator symbol now appears
after the linebreak, i.e. at the beginning of the new line.  Can I do
something about it?

Thanks and kind regards,
Joshua

Can you provide a working minimal example?

Sorry, please find an example at the end.

The first URL has the right linebreaks, but the arrow should be at the
end of the line.  Interestingly, it shows another problem:  the # is
repeated.

The second URL has a linebreak in front of the colon, which I do not
want.

Thanks and kind regards,
Joshua

The position of the \hyphenatedurlseparator symbol depends currently on the breakpoint in the url,
when the break is allowed after a character at the end of line but when the break is allowed before
a character the symbol appears at the begin of the line.

The question is now if this is intended or can it be changed. Another thing where we can discuss
is the way to set the separator, e.g. \sethypehantedurlseparator{…} seems more appropriate
than \def\hyphenatedurlseparator{…} because we already have other \setXXX commands.

Has to be fixed.

The points where contexts is allowed to break a url at :/# etc. are predefined in the Lua code.

When you want to change this you have to use the three commands

  - \sethyphenatedurlbefore{…}
  - \sethyphenatedurlafter{…}
  - \sethyphenatedurlnormal{…}

I can hardly imagine this to be intended.  The reader should be
informed about a break as soon as he reaches the break, so he knows the
word/token is not finished yet.  As we read from top to bottom, the
end of the top line is where this information should be.

Agreed.

Could you please change my minimal example (attached at the
end) accordingly? I want an URL like "http://optimist" to be wrapped
after "://" only, not in front of the colon.  I couldn't find out how to
achieve this.  I also want no linebreak to occur between two slahes
(if this is possible with the current implementation).  By the way, I
also don't understand the meaning of \sethyphenatedurlnormal {...}.

Kind regards,
Joshua


\setuplayout[width=5cm]
\sethyphenatedurlafter {/}
\sethyphenatedurlbefore {}

Word Word Word W \hyphenatedurl {http://optimist.optimist}

Word Word Word Wo \hyphenatedurl {http://optimist.optimist}

(Only the first of these three linebreaks is desired.)
