hyphenating urls and \tex

hyphenating urls and \tex

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \setuppapersize[A7]
    \define[1]\url{\useURL[url][#1]\from[url])}
    \starttext
    \hsize\zeropoint
    \tex{thisisthelongestcommandeverseen.com}
    \url{thisisthelongesturleverseen.com}
    \stoptext

In a beta from this year a new feature was introduced that enables
hyphenation in \tex commands.

How could I replace **only for \tex** the hyphenation character with an
underscore right below the previous character?

How could these hyphenation settings be added to \setupurl _besides the
ones from \hyphenatedurl_?

Locating the underscore below the previous character has the advantage
of avoiding the wrong impression that either the TeX command or the url
contain an underscore.

Manz thanks for your help,


Pablo

I have no time now to make a real mechanism ... maybe some day

\unexpanded\def\WhateverA#1%
   {\dontleavehmode
    \begingroup
    \prehyphenchar"B7\relax
    \setbox\scratchbox\hbox{\tttf#1}%
    \prehyphenchar`-\relax
    \unhbox\scratchbox
    \endgroup}

\unexpanded\def\WhateverB#1%
   {\dontleavehmode
    \begingroup
    \tttf
    \prehyphenchar\minusone
  % \localrightbox{\llap{_}}%
    \localrightbox{\llap{\smash{\lower1.5ex\hbox{\char"2192}}}}%
    \setbox\scratchbox\hbox{#1}%
    \prehyphenchar`-\relax
    \unhbox\scratchbox
    \endgroup}

\starttext
     \begingroup \hsize1cm
     \WhateverA{thisisaboringandverylongcommand}\par
     \WhateverB{thisisaboringandverylongcommand}\par

Many thanks for your reply, Hans.

Playing with your suggestion, I came to the following sample:

\definetype[TeXcode][option=TEX]

\unexpanded\def\underscorehyphenation#1%
   {\dontleavehmode
    \begingroup
    \prehyphenchar\minusone
    \localrightbox{\llap{\smash{\lower.1ex\hbox{_}}}}%
    \setbox\scratchbox\hbox{#1}%
    \prehyphenchar`-\relax
    \unhbox\scratchbox
    \endgroup}

\unexpanded\def\mex#1{\normalexpanded{\TeXcode{\letterbackslash#1}}}
\def\tex#1{\underscorehyphenation{\mex{#1}}}

\define[1]\url{{\tt\goto{\hyphenatedurl{#1}}}[url(#1)]}}

\starttext
\startTEXpage[offset=1em]
     \begingroup \hsize1cm
     \tex{thisisaboringandverylong[command}\par

     \url{thisisaboringandverylongcommand}\par
     \endgroup
\stopTEXpage
\stoptext

Is there a way to automatically detect (and apply it to the underscore)
the regular, bold font and its color?

Is there a way to apply both \hyphenatedurl and \underscorehyphenation
to an url?

Many thanks for your help,


Pablo
