== Description ==
Use this command to quickly execute some Lua code. TeX expands the argument ''before'' Lua receives it. Advantage: you can pass the contents of macro parameters like `#1` to Lua. Disadvantage: everything after a percent sign is ignored, and once the comments are processed out the linebreaks are stripped, too.
== Example ==
<context source=yes mode=mkiv>
\ctxlua{context(1+5)} % 6
%\ctxlua{context("5%")} % Is seen as `\ctxlua{context("5`
% 1, 2, 4, 8
\ctxlua{
context(1) % this comment is okay
i=2;
while i < 10 do
context(', ' .. i);
i = i*2
end}
</context>
