Good evening all,
interaction remains a mystery to me. When tracking things I encountered
the following deviation in footnotes:
---8<--------------------------------------------------------------------------
\startluacode
track = {}
track.preceding = ""
function track.simple(arg)
context("Last one:\\ {\\bf " .. track.preceding .. "}.\\ " ..
"This one:\\ {\\bf " .. arg .. "}")
if arg == track.preceding then
context("\\ -- matching!")
else
context("\\ -- not matching!")
track.preceding = arg
end
end
\stopluacode
\def\track#1{\ctxlua{track.simple("#1")}}
\def\foottrack#1{\footnote{\ctxlua{track.simple("#1")}}}
\starttext
\section{Normal}
\track{one}\par
\track{two}\par
\track{two}\par
\track{one}\par
\track{one}\par
\track{two}\par
\track{one}\par
\section{In Footnotes}
\foottrack{one}
\foottrack{two}
\foottrack{two}
\foottrack{one}
\foottrack{one}
\foottrack{two}
\foottrack{one}
\setupinteraction[state=start]
\section{In Footnotes, interaction enabled}
\footnote{\hrule}
\foottrack{one}
\foottrack{two}
\foottrack{two}
\foottrack{one}
\foottrack{one}
\foottrack{two}
\foottrack{one}
\stoptext
% vim:ft=context
---8<--------------------------------------------------------------------------
I'd naively expect \track#1 to behave identically regardless of
interaction. How do I make it interaction-proof, and, if possible,
how do I interaction-proof macros in general?
Thanks for your efforts,
Philipp

Try this:
print("TRACK:", arg)
> \def\foottrack#1{\footnote{\ctxlua{track.simple("#1")}}}
With interaction enabled, the argument to \footnote{} gets evaluated twice.
Cheers, Peter

eventually there will be a proper api for accessing footnote (and other)
data ... for instance, one can carry user data around and access that
later on

Sorry, I had forgotten to answer your main-question:
\def\foottrack#1{\expanded{\footnote{\ctxlua{track.simple("#1")}}}}
> and, if possible, how do I interaction-proof macros in general?
I don't know, but I suppose \expanded{} can help in most cases.
Cheers, Peter

Thanks very much, this does it!

Adding that one to my “try first”-list seems reasonable. There's a macro
\expanded defined in syst-aux.mkiv but it mentions certain “recent TeXs”
that have it builtin as a primitive -- which one am I using in mkiv?
The LuaTeXbook mentions an extra primitive “\expanded” taken from
pdfTeX. Are they equivalent?
Thanks a lot for your help!
Philipp

no, we had \expanded (and \protected and \unexpanded and ...) long
before they showed up as primitives
when \expanded was added, it was agreed that that name could be used
even if it clashed with context internals; ok, it add confusion for
users who use low level code, but as we always have \normalexpanded in
context it's no big deal; when in doubt, use \normal* for primitives (or
\primitive\expanded)
