\define
Syntax
| \define[...]\command{...} | |
| [...] | number |
| {...} | text |
Description
\define is like the TeX primitive \def: it defines a new TeX macro. Unlike
\def, it will not allow you to 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.
\define does not use \long, that means in MkII
multiple paragraphs (e.g. through \par or \endgraf)
inside arguments will not work.
comment
is there any bonus when I use \define instead of \def? -PG
Example
\define[1]\hello{Good morning, #1!} \starttext \hello{mom} \stoptext
