[NTG-context] Setting style and color attributes of label in metapost
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?

\setupcaption[picture][way=bytext,label=Picture] does the trick

Use can use “\setuplabeltext[en][picture=Picture ]” to set a label for “en-gb”.

Something like:
\definefloat[picture][pictures]
I'd then like the caption to read:
Picture 1 - my caption text
Picture 2 - etc
At the moment I've used \setupcaption[picture][way=bytext] to sort out
the numbering but I cannot figure out how to do the label.

Firstly, thanks for the reply. Secondly, apologies again for not
supplying a minimal example - this would have helped me track down
what's causing my issue.
\mainlanguage[en-gb] %% Remove me for labels
%\mainlanguage[en] %% or use me instead
\definefloat[picture][pictures] % Define our fancy boxout
\starttext
\placepicture{This is my caption}{Some float text}
\stoptext
The above will fail to generate a caption. Removing the \mainlanguage
command will cause the label to appear as expected. Using
\setuplabeltext[en-gb][picture=Picture ] will fail to work. Changing
the main language to 'en' or 'nl' will cause the label to reappear.
I'll change the main language to 'en' for the time being.
Thanks again for the help,
Felix

[NTG-context] math signs in itemize
