mode dependend character handling

mode dependend character handling

A happy new year!

I'd like to typeset a text in both German and Swiss German orthography,
i.e. I'd like to expand "s (or the like) to ß in German and ss in  
Swiss German mode,
or even better, automagically change ß to ss in Swiss mode.

This is what I have:
\startmode[swiss]
     \def\S#1{ss\relax}
\stopmode
\startnotmode[swiss]
     \def\S#1{\sz\relax}
\stopnotmode

That forces me to use \S{} in the middle of words, very ugly.
I know this is possible in a more sophisticated way! Please?
(My favorite solution would be to make ß expand to ss in Swiss mode.)

No doubt that's why spam for medication is so popular: you need
the medication to cope with the rest of the spam.

Likewise!

The correct way would be to define swiss as a language, because
then you can put a suitable redefinition inside the language
specifics, but the following hack will work as well and is a lot
faster to implement (please don't tell anyone I proposed this):

   \enableregime[il1]
   \let\normalssharp\ssharp
   \def\ssharp{\doifmodeelse{swiss}{ss}{\normalssharp}}
   \starttext
   {\enablemode[swiss] Grüßlis} Grüßlis
   \stoptext

Cheers, Taco

If everything is set OK in the regime you're using, this should work:

\startmode[swiss]
\definecharacter ssharp {ss}
\stopmode

Thank you, that works and is just the right solution for my problem.

Mojca's proposal:

> \startmode[swiss]
> \definecharacter ssharp {ss}
> \stopmode

unfortunately doesn't work, at least not with utf regime and ec  
encoding.

Since Taco's proposal is OK, you don't need this, but I'll reply
anyway. The problem is caused by "wrong order" of commands. If you
load ec encoding AFTER this command, your new definition of ssharp
will be overridden by the encoding definition again.

Compare:

\enableregime[utf] % may be whatever, no influence

\startmode[swiss]
    \definecharacter ssharp {ss}
\stopmode
\usetypescript[modern][ec] % or texnansi
\setupbodyfont[modern]
\starttext
Maß Bier! % fails (prints ß)
\stoptext

with:

\usetypescript[modern][ec] % or texnansi
\setupbodyfont[modern]
\startmode[swiss]
    \definecharacter ssharp {ss}
\stopmode
\starttext
Maß Bier! % prints ss
\stoptext

(Since ec encoding is the default one on my system, I had to use
texnansi in order to make the example fail.)

If you use a slightly longer variant

\startencoding[ec]
    \startmode[swiss]
        \definecharacter ssharp {ss}
    \stopmode
\stopencoding

than the order of commands doesn't matter any more (but then the
automatic conversion will only work for the ec encoding).

But now my question for Taco: why does your example work in both
cases? Does \def have a higher priority than \definecharacter?

Thanks,
    Mojca

ec is my default encoding, too, so I didn't use any changing commands.

No, it doesn't.
And I don't find any errors in the log.

mode processing is based on modes that are in effect
at the execution time of the \startmode macro, not
the typeset time. This would work:

   \enablemode[swiss]
   \startencoding[ec]
      \startmode[swiss]
          \definecharacter ssharp {ss}
      \stopmode
   \stopencoding

but then it would be on always, since it effectively becomes

   \startencoding[ec]
      \definecharacter ssharp {ss}
   \stopencoding

whereas without the \enablemode it becomes only:

   \startencoding[ec]
   \stopencoding

which does nothing.

HTH,

Taco

OK, thanks Taco. Now I understand the problem. I always compiled with or without
    texexec --mode=swiss
which worked fine. If mixing modes within the same document is
required (\enablemode/\disablemode[swiss]), it fails of course (I
didn't think about it).

Ah, ok, I didn't test with --mode, even if that will be my normal use  
case.

\startmode[*de]
  ...

languages have system modes (star prefix in order to prevent clashes 
with user modes)
