Subject: Setting style and color attributes of label in metapost
Date: Sat, 24 Sep 2011 20:43:53 -0400 (EDT) [thread overview]
Message-ID: <alpine.LNX.2.02.1109242022560.14346@ybpnyubfg.ybpnyqbznva> (raw)
I am writing a module which uses metapost in the background for drawing. I
wanted to create an interface for setting the style and color of metapost
labels but using \doset...attributes is not working.
Here is an example:
\definenamespace
[test]
[style=yes,
name=test,
command=yes,
setup=yes]
\definetest
[blue]
[color=blue, text=Blue]
\definetest
[two]
[blue]
[style=\bold, text=Two]
\starttext
\edef\currenttest{two}
\startMPdrawing
label.lft(\sometxt{\dosettestattributes{style}{color}
\testparameter{text}}, (0,0)) ;
\stopMPdrawing
\edef\currenttest{blue}
\startMPdrawing
label.lft(\sometxt{\dosettestattributes{color}{style}
\testparameter{text}}, (2cm,0)) ;
\stopMPdrawing
\MPdrawingdonetrue\getMPdrawing
\stoptext
Notice that the first label has the same style as the last label. This is
happening because \doset..attributes is defined as an unexpandable macro.
I can get around this by setting the value of \currenttest inside the
\sometxt{...} argument. Something like:
\def\dosometxt#1#2%
{\normaldosometxt{#1}%
{\def\noexpand\letterbackslash currenttest{\currenttest #2}}}
Surely, there should be a more direct way of achieving this?
Aditya
