Examples

Example Part 1 - Data for structs

Assume we have a CSV file containing a list of toys. There is a column for the toy name and another for the toys color.

name, color
Airplane, White
Bouncy Ball, Blue
Car, Red
Dog, Brown
Elephant, Gray
...

Example Part 2 - Populating structs

With the given CSV data we can quickly populate an array of structs.

//define struct
struct _toy {
    string name;
     string color;
}
//create struct array and populate from csv
_toy [] toys = readFromCSVFile("toysList.csv", true);

Example Part 3 - Mapping the struct array

Now that we have a list of structs we can map them to one of the fields.

string [] attachmentsCreatedToday;
for(string a in attachments) {
    string [] file = fileInfo(getAttachmentPath(key, a));
    date created = parseDate("yyyy-MM-dd hh:mm:ss", file["created"]);
    if(created > startOfDay(currentDate())) {
        attachmentsCreatedToday += a;
    }
}
return attachmentsCreatedToday;

Result: "Blue"
