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

[NTG-context] Re: using an end of line as parameter
Thanks a lot Bruce, that did the trick! definitely I will have to learn a bit lua in summer. I just got an error on \qquad and found searching in internet that it was because escape character conflicts between tex and lua. For the time i removed it and since I will create itemizes I hope I dont get that error if I use \item instead of \qquad. Thanks again, I spent hours of trial and error, error, error... on this matter. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

A variation on Hans original suggestion is to use a buffer instead of a
separate text file, combined with Lua.
\startluacode
userdata = userdata or {}
function userdata.formatTestQuestions()
local the_buffer = buffers.getlines("TestQuestions")
local tracker = 0
local the_question = {}
local letters = {"-", "a", "b", "c"}
-- 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.startlines()
context("{\\bf Beispiel:} %s", the_question[1])
context(true)
for answer = 2,4 do
context("\\qquad %s) %s", letters[answer], the_question[answer])
context(true)
end
context.stoplines()
-- 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()}}
\starttext

[NTG-context] Re: using an end of line as parameter
no, I just want to split at the end of each sentence to get the four arguments:
now I pass this four lines to my macro \tareaAbc (with the dirty trick of ñ)
In den Büchereien gibt es auch …ñ
… Kuchen.ñ
… Theater.ñ
… Workshops.ñ
and I wish your context.foo(lines[i]) iteration would become a single
context.tareaAbc(the four arguments somehow separated so that I can manage each
line with the corresponding context formatting)
As you see my definition is: \def\tareaAbc #1ñ#2ñ#3ñ#4ñ{...context formating
for each #)}; Its the clue to pass each sentence as an independent argument
that I don't get to work.
thanks again
Miguel

You have to provide more details about these lines. For instance, do you
want to split on spaces?

Dear list,

(comments are mine)

I need to detect \par or whatever sign marks the newline character as an
argument delimiter so that I dont have to paste hundreds of times braces
for each argument.
For the example, I use this macro definition (which does no work!)
\long\def\prueba
#1\par#2\par#3\par#4ñ{\framed[frame=off,width=0.8\textwidth,corner=round,offset=1em,align=flushleft]%
{{\bf Beispiel}: #1\\
\qquad a) #2\\
\qquad b) {\bf #3}\\
\qquad c) #4
}
I get: tex error on line 493 in file ./prueba.tex: The file ended when
scanning an argument.
the macro seems to read to the end of file not detecting \par; I know
its the \par that causes the problem; I used ^^M also which I read is a
sinonym for return but it also does not work.
Help would be appreciated (my computer keyboard would appreciate it too...)
better start thinking something:
\starttext
\def\foo#1{<<<#1\par}
\startluacode
local s = [[
line 1
line 2
line 3
line 4
]]
-- local s - io.loaddata("yourfile.txt")
local lines = string.splitlines(s)
for i=1,#lines do
if lines[i] ~= "" then
context.foo(lines[i])
end
end
\stopluacode
