Re: [NTG-context] using variable for subscript in math+lua (and math+MetaFun)
Dear Hans,
The structure of your code is very interesting.
MP code) inside ConTeXt) inside Lua) inside ConTeXt) again!
It is really useful.
Thank you.
Best regards,
Dalyoung

play with code like this
\starttext
\startluacode
context.startMPcode()
for i=1,10 do
for j=1,10 do
context('draw (%scm,%scm) withpen pencircle scaled 2mm
;',i,j)
context('draw
thetextext.top("\\tt%s,%s",(%scm,%scm+2mm)) ;',i,j,i,j)
end
end
context.stopMPcode()
\stopluacode
\stoptext

Re: [NTG-context] using variable for subscript in math+lua (and math+MetaFun)
Dear Gesang and Hans,
Your solution is working nicely.
I may use lua to simplify my other work.
I'd like to ask you one more thing.
I tried to write a matrix using MetaFun to add some graphics as following:
label(btex $a_{11}$ etex, ( , ));
label(btex $a_{12}$ etex, ( , ));
label(btex $a_{13}$ etex, ( , ));
…
label(btex $a_{3,3}$ etex, ( , ));
Since the same command is repeated, I tested to use "for" iteration.
But I couldn't succeed. It is OK to use the variable as a text but I couldn't
find a way to use a variable as a subscript.
For example,
for i=1 unto 3: label(btex decimal(i) etex, (x,y)); endfor;
is OK. But,
for i=1 upto 3: label(btex $a_{i}$ etex, (x,y)); endfor;
or
for i=1 upto 3: label(btex $a_{deciaml(i)}$ etex, (x,y)); endfor;
are not working as I wanted.
Is there a way to use variable as a subscript in "label"?
Thank you again.
Best regards,
Dalyoung
