reading the value of a counter (footnote counter, i.e.) from lua

reading the value of a counter (footnote counter, i.e.) from lua

[massifr]

Hello list,
how can I read the numeric value of a counter in Lua?

local c_value = ...

Something like \rawcountervalue in ConTeXt, but in Lua.

Thanks in advance,
Massi

\starttext

x \footnote{x} x \footnote{x} x \footnote{x} x

\cldcontext{structures.counters.currentvalue("footnote",1)}

\stoptext

Thank you, Hans.

I searched for "currentvalue" in the source and now I'm looking at "strc-num.lua".
Is the second argument of currentvalue the level of a multi-level counter?
I suppose it is always 1 in footnotes, isn't it?

Best regards,
Massi

No, you can also use 2 for \subfootnote and 3 for \subsubfootnote.
