I'm trying to create a ConTeXt macro (mkiv) that will manipulate the
macro argument's text with Lua and then feed it back into ConTeXt
with tex.print(). My approach worked correctly until I called the
macro with \starttabulate ... \stoptabulate in the macro's
argument. So I started reducing the problem down to a minimum
example which surprisingly turned out to have nothing to do with the
manipulations I was performing.
Here is the working example (without \starttabulate):
\long\def\testmacro#1{\directlua0{d='\luaescapestring{#1}'}}
\starttext
Hello, world!
\testmacro{%
testing}
\stoptext
Here is the broken example:
\long\def\testmacro#1{\directlua0{d='\luaescapestring{#1}'}}
\starttext
Hello, world!
\testmacro{%
testing
\starttabulate
\NC 0 \NC testing tabulate. \NC \NR
\stoptabulate}
\stoptext
\def\testmacro
{\bgroup
\catcode`\\=12
\dotestmacro}
\def\dotestmacro#1
{\ctxlua{d='\luaescapestring{#1}'}%
\egroup}
\starttext
\testmacro{\starttabulate \NC text \NC text \NC\NR \stoptabulate}
%\ctxlua{tex.sprint(d)}
\stoptext
