Dear sirs, In my project I need to format some data from a csv file. The csv file is scanned using the scancsv module and part of this information is formatted inside luacode environment, but the text.print("") and the context("") functions don´t be able to send the formatted data to the output. The result is a empty pdf. The example attached is from a old question. Thanks a lot for your time Jorge M. --- example -- \usemodule[scancsv] \def\ddmmyyyy#1#2#3{% #1 - date, #2 - old separator, #3 - new separator \startlua local parsedate=thirddata.scancsv.ParseCSVLine('#1','#2'); local day=tonumber(parsedate[1]); local month=tonumber(parsedate[2]); local year=tonumber(parsedate[3]); -- tex.print(day..'#3'..month..'#3'..year); text.print("Hello"); \stoplua } \unexpanded\def\lineaction{ \Name\ arrived on \ddmmyyyy{\Date}{/}{.\\,} \\ } % Name;Date % ME;11/10/14 % You;05/02/14 % He;15/02/2014 % She;03/03/12 % It;03/03/14 \setheader \setsep{;} \setfiletoscan{mail.csv} \starttext \filelineaction \stoptext
