[NTG-context] ctxlua percentage format escape
Hi,
I was trying to use a quick calculation like the new mathfun in lmtx for an
older mkiv document.
MWE from the wiki:
https://wiki.contextgarden.net/Programming_in_LuaTeX#Examples
\starttext
$\pi = \ctxlua{context("\%.6f", math.pi)}$
\stoptext
But that gives an error (actually for both lmtx and mkiv): token call,
syntax: [ctxlua]:1: invalid escape sequence near '"\%'
Whereas
\starttext
$\pi = \startluacode context("%.6f", math.pi) \stopluacode$
\stoptext
Works fine as expected.
Is there a way to escape the percentage sign in ctxlua as a format value?
Adam
