Czech compound word handling

Czech compound word handling

[David Antos]

	Hello,

would it be possible to define || for compound words to act as
\discretionary{-}{-}{-}? In Czech, the hyphen for compound words should
be repeated in the following line.

Thanks,
D.A.

you mean something like this:

\unprotect

\def\activedododotextmodediscretionary#1#2%
   {\convertargument#2\to\discretionarytoken
    \def\textmodediscretionary%
      {\getvalue{\strippedcsname\textmodediscretionary\string#1}}%
    \ifx\discretionarytoken\empty
      \ifx#1\nextnext % takes care of ||| and +++ and ......
        \prewordbreak\discretionary{\hbox{$#1$}}{}{\hbox{$#1$}}%
        \allowbreak\postwordbreak
        \def\nextnextnext{\afterassignment\egroup\let\next=}%
      \else
        \checkafterdiscretionary
        \bgroup
          \checkbeforediscretionary
	 \textmodediscretionary\nextnext
        \egroup
      \fi
    \else\expandafter\ifx\csname\@tmd@\discretionarytoken\endcsname\relax
      \checkafterdiscretionary
      \bgroup
        \checkbeforediscretionary
        \prewordbreak
        \discretionary{\hbox{#2}}{}{\hbox{#2}}%
        \allowbreak\postwordbreak
      \egroup
    \else
      \csname\@tmd@\discretionarytoken\endcsname
    \fi\fi
    \nextnextnext} % can be \egroup so \aftergroup\ignorespaces

\startlanguagespecifics[cz]

   \setvalue{\strippedcsname\textmodediscretionary\string|}%
     {\discretionary{-}{-}{-}}%

\stoplanguagespecifics

\setvalue{\strippedcsname\textmodediscretionary\string|}%
   {\prewordbreak\hbox{\compoundhyphen}\allowbreak\postwordbreak}

\protect

\starttext

\en \dorecurse{100}{test||}test \endgraf
\cz \dorecurse{100}{test||}test \endgraf

\stoptext


so, in principle it is possible but i need to make it a bit nicer; maybe tonight -)

Wow, that's exactly what we need. I suggest to make this also
default setting for Czech.

Thank you,

It caused a recurse error in my cont-cz format (standard only english 
interface), see attch.

This mechanism is already present in the ConTeXt: use |_| like 
"bude|_|li". Unfortunately, AFAIK there are two drawbacks:

1) From some time the hyphen started to be defined
   \def\compoundhyphen{\hbox{-\kern-.25ex-}}
but for Czech is better:
   \def\compoundhyphen{-}
I intend to incorporated it to Czech support. (cont-cz.tex ?)

2) This kind of |.| does not operate inside with XML processing.
Here is minimal example sent last week:

-----
\defineXMLentity[hyphen]{|_|}
\starttext
   dojde|_|li
   \startXMLdata
     dojde‐li
   \stopXMLdata
\stoptext
------

Hello,

this ispired an idea: would it be possible to make the characters
configurable? I.e. to have in fact || configurable for pre-break,
post-break, and no-break character? I think it might be generic enough
for most languages.

Say, we would have
\setuphyphenmark[.. = ..]
sign ... (for backwards compatibility, would set up all the following)
presign ...
postsign ...
nosign ...
