hyphenation blues

hyphenation blues

[Steffen Wolfrum]

Hi,

please have a look at the following unfairness:


\mainlanguage[en]
\enableregime[utf]
\showframe

\setupcolors[state=start]

\def\Textit%
{\groupedcommand\em\/}

\define[1]\Colorit%
   {\color[blue]{\groupedcommand\em\/ #1}}

\starttext

text text text text text text text text text text text text text text  
text text "\Textit{hyphenation}"

text text text text text text text text text text text text text text  
text text "\Colorit{hyphenation}"

\stoptext



Is there a trick to turn on hyphenation again?

Steffen

Try this:

\define\Colorit%
   {\groupedcommand{\color[blue]\em}\/}

Best wishes,
Taco

You are running pdftex, 'cause it worked fine in mkiv :-)

\def\Colorit%
   {\groupedcommand{\color[red]\em\penalty10000\hskip0pt }\/}

The penalty and skip are needed because the \color generates
a node that prevents the next word from hyphenating.

Best wishes,
Taco

I still got the blues!

It works fine for normal text, but try it in footnotes (test below)  
and you'll get in mkii:

! You can't use `\end' in internal vertical mode.
<recently read> \normalend



\mainlanguage[en]
\enableregime[utf]
\showframe

\setupcolors[state=start]

\def\Textit%
{\groupedcommand\em\/}

\def\Colorit%
   {\groupedcommand{\color[red]\em\penalty10000\hskip0pt }\/}

\starttext

test\footnote{text text text text text text text text text text text  
text text text text text text text text "\Textit{hyphenation}"}

test\footnote{text text text text text text text text text text text  
text text text text text text text text "\Colorit{hyphenation}"}

\stoptext

Jikes. Looks like that is because \color is a \groupedcommand  itself.
This works for this test file (and hopefully for everything  else):

\def\Colorit%
    {\groupedcommand
       {\startcolor[red]\em\penalty10000\hskip0pt }
       {\/\stopcolor}}

Best wishes,
Taco

\color expects an argument

\def\Colorit%
   {\groupedcommand
      {\startcolor[red]\em\penalty10000\hskip\zeropoint}
      {\stopcolor\/}}

works! and that from Hans too.

Hans ends with ... {\stopcolor\/}}
Tacos with ... {\/\stopcolor}}


Sorry, this is too sophisticated for me to figure out:

Which one is better, i.e. more robust?



Thanks you two!!

Steffen

depends on how \/ is implemented, as lookback or lookforward, just see 
what works best
