Ah, thanks, that looks like what I need, or at least part of it, and
will keep me busy making more experiments.

Sorry, I forgot to say that I had tried that version too but also with
no luck. Also, either version of onerg works as expected if I delete
the context.beginanswer() and the \endanswer lines.
the problem is that you effectively use buffers so you have a different
catcode regime ... i'm not sure what you want but thsi might give a clue
\starttext
\defineblock[foo]
\beginfoo
test 1
\endfoo
\startluacode
buffers.assign("temp","test 2")
structures.blocks.save("foo",nil,nil,"temp")
\stopluacode
\useblocks[foo]
\stoptext
there are mechanisms for templates for constructing more meaningful
content than "test 2" (see test suite)

Dear List,
I've been trying to construct part of a block's content programmatically
with Lua. Despite many experiments and much rereading of the cld manual
(especially chapter 3 on functions), the following attempt fails for
reasons that perplex me. Below is the MNWE (Minimal NonWorking
Example). It fails with these lines in the log file:

That is, when the "answer" block is included via \useblocks, somehow the
beginning of the answer, which should be "\onearg{Test parameter}", has
its curly braces and spaces elided.
What characteristic(s) of the Lua interface am I missing? Thank you if
you happen to where I've gone wrong. I've also tried steppers without
much luck (and, admittedly, without really understanding their use).
