\definecharacter

\definecharacter

[Thomas A. Schmitz]

Hi all,

is the command \definecharacter deprecated in mkiv? Some of my  
environments stopped working. Minimal example:


%\definecharacter mytest \char"00F8
\define\mytest{\getglyph{name:lmroman10book}{\char"00F8}}

\starttext

Hello w\mytest rld!

\stoptext

I expected lines 1 and 2 to work, but line 1 gives an error  
("Undefined control sequence"). So: is this command no longer  
available in mkiv?

All best

Thomas

from enco-ini.mkiv

\def\definecharacter#1 #2 %
   {}

You could use \definecommand.

Wolfgang, thanks for pointing me to this. What is the reason of this  
unfriendly behavior? I can understand if the \definecharacter command  
is gone in mkiv, but simply taking the arguments and sending them into  
nirvana? It was a bit difficult for me to see where the errors in my  
environments came from, so I'm really wondering what this is supposed  
to do.

(i can make it a chardef if needed)

Hey, you should know that your users use ConTeXt for all kinds of  
weird and deviant purposes :-)

I have it in some of my private modules/environments, e.g. for  
creating symbols and a metrical font. What would you suggest using  
instead?

Best

Thomas

\definecharacter etc were closely related to font encoding, so unless 
you defined them in 'default' encoding you had to replicate the 
definitions in each fotn encoding

a more natural variant for your case is \definesymbol or just 
\def\MyFunnySymbol{...}

Even in XeTeX or LuaTeX one had to define a character only once.
\definecharacter worked just fine in both of them some time ago and I
find it a pitty to remove it (if there is no serious reason to do so).

\def\definecharacter#1 #2 %
   {\doifnumberelse{\string#2}
      {\setevalue{\string#1}{\utfchar{#2}}}
      {\unexpanded\setvalue {\string#1}{#2}}}
