! LuaTeX error <main ctx instance>:1: ')' expected near '<eof>'.
<inserted text> ....pitex.print("pi = " .. (x - x}
This in spite of the wiki telling me:
To circumvent this problem, ConTeXt defines a environment called \startluacode ... \stopluacode. This sets the catcodes to what one would expect in lua. Basically only \ has its usual TeX meaning, the catcode of everything else is set to other. So, for all practical purposes, we can forget about catcodes inside \startluacode ... \stopluacode.
\startxmlsetups xml:mycommand
\startluacode
local x = math.pi
tex.print("pi = " .. (x - x\%0.01))
\stopluacode
\stopxmlsetups
When I try to escape the % with \% the result is no better:
! LuaTeX error <main ctx instance>:1: ')' expected near '\'.
<inserted text> ...rint("pi = " .. (x - x\%0.01))}
Is it not possible to directly use Lua inside these setups? If do, why the nonconforming behaviour?
