Hi Pablo
Here is a quick solution. However, it not treat the incorrect input
data, ie it requires, however, correct input, otherwise it will collapse ...
Jaroslav Hajtmar
\usemodule[scancsv]
\def\ddmmyyyy#1#2#3{% #1 - date, #2 - old separator, #3 - new separator
\startlua
parsedate=thirddata.scancsv.ParseCSVLine('#1','#2');
day=tonumber(parsedate[1]);
month=tonumber(parsedate[2]);
year=tonumber(parsedate[3]);
if (year<2000) then year=year+2000 end;
tex.print(day..'#3'..month..'#3'..year);
\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
