Dear list,
I have the following sample:
\starttext
\startluacode
function document.print_the_thing(str)
context(str)
end
\stopluacode
\unexpanded\def\PrintTheThing#1{%
\ctxlua{document.print_the_thing([[\luaescapestring{#1}]])}}
\PrintTheThing{a \em b {c}}
\stoptext
I wonder whether there is a proper way in the Lua code to avoid
[[\luaescapestring{}]] in \ctxlua.
BTW, [[\luaescapestring{}]] in \ctxlua works better for me, since in my
real world document, I’m using str:match() to check whether the string
ends with interrogation or exclamation marks ("%?!$").
Many thanks for your help,
Pablo

\starttext
\startluacode
function document.print_the_thing()
context(tokens.scanners.string())
end
\stopluacode
\protected\def\PrintTheThing{\ctxlua{document.print_the_thing()}}
\PrintTheThing{a \em b {\bf c} d}
\stoptext
bonus:
test!\removepunctuation ?

Many thanks for your reply, Hans.

Sorry, but why \protected is required or recommended here?
Many thanks for your help,
