some minor problems (mkiv)

some minor problems (mkiv)

[Peter Rolf]

hi,

i'm still trying to make my code run with mkiv. here are two minor 
problems. the first one is easy to deal with, but the second one 
currently breaks my testbed.


% engine=luatex
\setupcolors[state=start]

\starttext

\startMPcode
label("no color",origin) withcolor red; % always black
\stopMPcode

\string{\{}

\stoptext


greetings, peter

Interesting problem, that one. The lack of color is easily explained
because there is an implied textext() around the string., but it is
not that easily solved, I suspect.

> \string{\{}

Side note wrt. the example: don't you want \string\{ instead?

Anyway, the underlying problem is something for Aditya to look at,
maybe. Too many commands are now 'math mode only' because of changes
in char-def.lua.

Best wishes,
Taco

i currently use sometxt() instead (was label because of much better 
runtime in mkii). i guess it's one of the last places where i use text 
inside mp, so it doesn't hurt that much. mh, maybe i should extract the 
outlines (it's only one char) instead.

nope. the argument is a formal macro description with parameters in 
braces and brackets. it's part of the testbed for my graphic macros.

thanks wolfgang! but sadly it's not the only argument of \string (my 
example was bad).

best wishes, peter

actually this was a bug but probably only taco has the version that 
fixes it (after all, we must stay at least a week ahead of you)
