Command/define
\define
Syntax
\define[...]\command{...} | |
[...] | number |
{...} | text |
Description
\define
is like the TeX primitive \def
: it defines a new TeX macro. Unlike \def
, \define
can never redefine an already defined command.
The optional bracketed argument denotes the number of parameters you can give to your command. "text" is the result when the macro gets expanded.
Pitfalls
\define
does not use \long, that means in MkII
multiple paragraphs (e.g. through \par or \endgraf)
inside arguments will not work.
The name of the new command may not include numbers.
Example
% wiki mode=mkiv \define\hello{Good morning} % You may not use numbers % \define[1]\mp3{The ID3 Tag of the MP3 file is: #1} % but this will work: \define[1]\mpThree{The ID3 Tag of the MP3 file is: #1} % You can use non-ASCII characters in MkIV, but not in MkII. % This example is compiled using mkiv. \define[1]\KüFst{Küstenfunkstelle, #1!} \starttext \hello \KüFst{12} \stoptext
