Problem to read file .txt and to transform this as a tuple's instance - opl

Question

I have a .txt file i want to read it and transform it into instance so that the tuples can read it
My text file contains:
day 7h 20h
care amy baba
care baba bintou
I want to read the text file and get the following data:
day = <7.20>
care = [<"amy", "baba">
<"bintou", "baba">
]
Script is as follows:
// Reads the content of a file and returns its content as a string
function file_to_string(files) {
var f = new IloOplInputFile(files);
if (f.exists) {
// writeln("Reading file : ", fichier );
var s = "";
var indent = "";
var tab = new Array();
while (!f.eof) {
s = s + f.readline() + "\n";
s = s.split(" ");
}
write(s);
f.close(); // Fermeture fichier instance
}
else
writeln("\nWARNING : the file ", files, " doesn't exist");
return s;
}

You have to define the appropriate tuples and create (empty) sets of them. Then you can use the tuple set's add function to add new tuples to the set.
This .mod file
tuple day {
int field1;
int field2;
}
{day} days = {};
tuple care {
string field1;
string field2;
}
{care} cares = {};
execute {
var f = new IloOplInputFile("readtuple.data");
while (!f.eof) {
var s = f.readline();
var fields = s.split(" ");
if ( fields.length < 2 )
// empty or invalid line
continue;
if ( fields[0] == "day" )
days.add(Opl.atoi(fields[1]), Opl.atoi(fields[2]));
else if ( fields[0] == "care" )
cares.add(fields[1], fields[2]);
else {
// invalid line
}
}
f.close();
}
execute {
writeln(days);
writeln(cares);
}
Produces this output with your data:
{<7 20>}
{<"amy" "baba"> <"baba" "bintou">}
