Hi Pablo,
I am sending still slightly modified version (use local variables and
better typographic output).
It use of much variables, but at least it is clear how it works. For
solution occurred me to use parsing function that I have been defined in
the library, so that it can be successfully used.
Sincerely
Jaroslav Hajtmar
\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]);
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

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 ...

\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

Dear list,
I have the following sample:
\usemodule[scancsv]
\unexpanded\def\lineaction{
\Name\ arrived on \Date\\
}
\setheader
\setsep{;}
\setfiletoscan{mail.csv}
\starttext
\filelineaction
\stoptext
that reads data from mail.csv:
Name;Date
ME;11/10/14
You;05/02/14
He;15/02/2014
She;03/03/12
It;03/03/14
My question is simple (and not related to CSV data import): how can I
define a command (ConTeXt or Lua) that changes date format from DD/MM/YY
to DD/MM/YYYY when required?
Many thanks for your help,
Pablo
