Hi all,
what is the better way to apply a metapost effect to a piece of any structure
text
for example when defining footnotes, frames , etc.
i use this method for frames:
this is my MWE:
\defineframed[Myframe][frame=off]
\starttexdefinition spaces protected Mystyle #1
\startMPcode
picture tt ; tt:= lmt_outline [
kind = "path",
text = "\Myframe{#1}",
];
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red,blue);
\stopMPcode
\stoptexdefinition
\starttext
\Mystyle{hello}
\stoptext
but what is the proper way if i want to use this style as simple as \tfb in
definition of this structures? such as:
\defineframed[Myframe][frame=off,style=\tfb\Mystyle,]
You can't apply commands which take arguments (like \Mystyle) to pass
content fro TeX to Metapost with the style key. The only solution here
is to create a new commands which takes the content as argument and
combine the frame and shade in the command definition.
\defineframed[Myframe][frame=off]
\starttexdefinition spaces protected Mystyle #1
\startMPcode
picture tt ; tt:= lmt_outline [
kind = "path",
text = "#1",
];
fill
for i within tt : pathpart i && endfor cycle
withshademethod "linear"
withshadedirection up
withshadecolors (red,blue);
\stopMPcode
\stoptexdefinition
\define[1]\Mycommand
{\Myframe{\Mystyle{#1}}}
% \define[1]\Mycommand
% {\Mystyle{\Myframe{#1}}}
\starttext
\Mycommand{hello}
\stoptext
