When trying to typeset, luatex kept complaining about incorrect parameters for ‘minus’. There is no \minus command in the source however. So it turns out that the combination of using \quad with ‘plus’, 'minus', and some more make the error appear. If i rewrite minus by {minus} the error does not show up either.
That's because the skips in spac-hor.mkiv are defined like this \unexpanded\def\enskip{\hskip.5\emwidth} \unexpanded\def\quad {\hskip \emwidth} \unexpanded\def\qquad {\hskip 2\emwidth} The syntax for the \hskip primitive is \hskip<glue> and the definition of <glue> is <dimen>plus<dimen>minus<dimen> So “\quad minuskel” will expand to “\hskip\emwidth minuskel”. You see what's going to happen? The “minus” will be interpreted as part of the glue definition but no <dimen> is following it, so you get an error. To fix the bug, the definitions in spac-hor.mkiv have to changed \unexpanded\def\enskip{\hskip.5\emwidth\relax} \unexpanded\def\quad {\hskip \emwidth\relax} \unexpanded\def\qquad {\hskip 2\emwidth\relax} As a temporary workaround you can also just copy them into your document.
\starttext \quad minuskel \stoptext
Where do i go wrong?
Thanks. Floris
