Libvalentine

A library that can convert a CSV file to GLib.Objects and viceversa. For example:

public class Example : Object {
    public string name { get; set; default = "hello"; }
    public int something { get; set; default = 1; }
    
    // This property is private read, therefore it won't appear in the CSV file
    public bool boolean { private get; set; default = false; }
}

var serializer = new Valentine.ObjectSerializer<Example> ();
example.add_object (new Example ());
example.add_object (new Example () { name = "Hola" });
example.add_object (new Example () { something = 2 });

Will have the following output:

name,something
"hello","1"
"hola","1"
"hello","2"

Parsing a CSV text is done in the following way:

string csv = """name,something
"Object 1,"45"
"Object 7","19"
"Object 9","13"
"""

var deserializer = new Valentine.ObjectDeserializer<Example> ();
List<Example> object_list = deserializer.deserialize_from_string (csv);

foreach (var object in Example) {
    print ("name: %s; something: "%i", object.name, object.something);
}

/*
 * Output:
 * name: Object 1; something: 45
 * name: Object 7; something: 19
 * name: Object 9; something: 13
*/

Usage

Valentine provides a simple API that converts GLib.Objects into a CSV file.

var serializer = new Valentine.ObjectSerializer<Adw.Flap> ();
serializer.add_object (new Adw.Flap ());
serializer.add_object (new Adw.Flap ());

stdout.printf (serializer.to_string ());

It also provides an option to save the document directly to a file:

serializer.save_to_file ("/var/home/user/Documents/my_file.csv");

It also provides an API that converts CSV files to Object Lists

var deserializer = new Valentine.ObjectDeserializer<Adw.Flap> ();
List<Adw.Flap> list = deserializer.deserializer_from_file ("/path/to/csv/file.csv");
