Hi David,

Petr Olsak has changed slightly Czech pattern file czhyph.tex for TeXlive2003, it's a bit `Babelized' now. It produces \errmessage for Babel's \addlanguage being \undefined. It also contains several ugly hacks to make both plain and LaTeX read \v and ' syntax for Czech accents, and finally it reads czhyphen.tex containing real patterns.

The result is that generating ConTeXt format ends with the \errmessage. Simple workaround is to change alias in cont-usr.tex to pattern files from czhyph.tex to czhyphen.tex. My discussion with Petr Olsak suggests to make a more systematic correction: to add a test into czhyph.tex and make it directly read czhyphen.tex if ConTeXt is detected.

This needs two things to make sure:

1. Is it OK to read patterns with \v and ' syntax into ConTeXt?
2. Is there a way to detect ConTeXt in order to put into czhyph.tex

something like:

\ifx<something-typical-to-detect-ConTeXt>\undefined \else % for ConTeXt \input czhyphen.tex \endinput \fi

Is there a more systematic/clean solution? Or shall I ask Petr Olsak to change this in the czhyph.tex file?

Ah ... i just found that out yesterday and had on my agenda to ask you to look into it. I have now adapted cont-usr.tex and commented:

% \definefilesynonym [lang-cz.pat] [czhyph.tex] % \definefilesynonym [lang-cz.pat] [skhyph.tex]

maybe you can trigger on:

\contextversion

Thanks for taking care of it.
