[Vala] [ANNOUNCE] Vala 0.19.0 - Compiler for the GObject type system
We are pleased to announce version 0.19.0 of Vala, a compiler for the GObject type system. Vala 0.19.0 is now available for download at: http://download.gnome.org/sources/vala/0.19/ Changes since 0.18.1 * Support scope = "async" attribute for parameters. * Add --api-version option. * Add atspi-2 bindings. * Add gstreamer-rtsp-server-1.0 bindings. * Bug fixes and binding updates. Vala is a programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C. valac, the Vala compiler, is a self-hosting compiler that translates Vala source code into C source and header files. It uses the GObject type system to create classes and interfaces declared in the Vala source code.

I guess I could write the interface, but what I want to be able to do
is, e.g., simply create a type by passing an int to the generic, then
have the class be able to see if it's type (int in this example). has a
to_string() method. For example:
public interface IStringable {
public abstract string to_string();
}
public class StringableClass : IStringable, Object {
public string to_string() {
return "foo";
}
}
public class NotStringableClass : Object {
}
public class Printer {
T obj;
public Printer(T val) {
obj = val;
}
public void print() {
if (obj is IStringable) {
stdout.printf("%s\n", ((IStringable) obj).to_string());
} else {
stdout.printf("Not printable.\n");
}
}
}
void main() {
var i = 10;
var yes = new StringableClass();
var not = new NotStringableClass();
var i_p = new Printer(i);
var yes_p = new Printer(yes);
var not_p = new Printer(not);
yes_p.print();
not_p.print();
stdout.print("%s\n", i.to_string());
i_p.print();
}
valac compiles this fine, but when it gets to i_p.print() it segfaults.
What I want to be able to do is say "yes, I see that int has a
to_string() method" and call it.

Re: [Vala] Generics and .to_string()
There is no such but you can write that interface:
For example:
public interface IStringable {
public string get_string();
}
...extendable as needed.

[Vala] Generics and .to_string()
I would like to use a Generic class, so
class MyClass {
T property;
...
public void Print() {
stdout.printf(property.to_string())
}
}
The compiler fails with:
The name `to_string' does not exist in the context of `T'
And that does kinda make sense to me, the question is.. I guess in a
generic fashion:
How can I call a method on a Generic type? For the above example, I've
tried casting:
((Object) property).to_string() tells me that GLib.Object has no
to_string() (I thought it did, but may have confused it with C#'s
object.
(string) property compiles but segfaults.
Is there an Interface for to_string() i can check for, e.g:
if (property is IStringable) ((IStringable) property).to_string()
Thanks,
-a
