Visualcounter: style parameter not working as expected

Visualcounter: style parameter not working as expected

[Romain Diss]

Hi all,

I'm actually using the visualcounter module for a presentation and I can't 
modify the style of the page number inside the countdown counter. The 
documentation let me think the 'style' parameter should do the job but it 
doesn't seem to work.

Do I miss something or is this a bug?

%% Minimal working exemple %%%%%%%%%%
\usemodule[visualcounter]

\definevisualcounter
  [test]
  [countdown]
  [counter=userpage]

\setupvisualcounter
  [test]
  [style=\tfd] % This is not taken into account

\setupfootertexts[][\usevisualcounter{test}]

\starttext
  \dorecurse{3}{\input knuth \par \input knuth \page}
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Thanks in advance.

This is a bug. Thanks for the report. I have fixed it on the github dev 
branch, and will upload a new version soon.

In case anyone is interested, this is what was happening:

Context parses the parameter of `\useMPgraphic` to 
determine the MP instance. The code was using

     \useMPgraphic{\visualcounterparameter\c!mp}

`\useMPgraphic` does not expand its arguments, so the proper MP instance 
was not initialized. Changed the above line to

     \expanded{\useMPgraphic{\visualcounterparameter\c!mp}}

and now style and color parameters work.

even if it would expand, then we still can have an issue when the 
definer uses a macro as that one doesn't get expanded either, like:

\starttext

\def\xxx{x}

\startuseMPgraphic   {\xxx 1} draw  fullcircle scaled 1cm ; 
\stopuseMPgraphic
\startuniqueMPgraphic{\xxx 1} draw  fullcircle scaled 1cm ; 
\stopuniqueMPgraphic

\def\xxx{xx}

     \useMPgraphic{x1}
     \uniqueMPgraphic{x1}

\stoptext

this is seldom an issue, but for convenience I patched the definers and 
resolvers so that the first argument gets expanded (next upload)
