Yes, the \'s need to be escaped in Lua. And it's made me realise that the
process of identifying the four lines of the question is separate from the
typesetting of the question later. The amended version below uses your
\tareaABC macro to format the question so you can more easily change the layout
without having to understand ConTeXT Lua Documents in detail.
\startluacode
userdata = userdata or {}
function userdata.formatTestQuestions()
local the_buffer = buffers.getlines("TestQuestions")
local tracker = 0
local the_question = {}
-- Go through the buffer of questions one line at a time
for i = 1,#the_buffer do
-- Skip blank lines but 'collect' non-blank lines until we have four
-- (which is assumed to be a whole question)
if string.strip(the_buffer[i]) == "" then
tracker = 0
the_question = {}
else
tracker = tracker + 1
the_question[tracker] = the_buffer[i]
end
-- If tracker has got to 4 then we've read four lines
if tracker == 4 then
context.tareaAbc(
the_question[1],
the_question[2],
the_question[3],
the_question[4])
-- Reset for the next question (in case no blank line)
tracker = 0
the_question = {}
end
end
end
\stopluacode
\def\startTestQuestions
{\dostartbuffer[TestQuestions][startTestQuestions][stopTestQuestions]}
\def\stopTestQuestions
{\ctxlua{userdata.formatTestQuestions()}}
\define[4]\tareaAbc{\item #1
\startitemgroup[itemize][a]
\item #2
\item #3
\item #4
\stopitemgroup}
\starttext
