Re: [Vala] Support for coroutines in Vala
Replace first line with:
async void foo () {
and compile with --pkg gio-2.0

Support for coroutines in Vala:
Has it been dropped ?
otherwise how does one compile examples like:
/
void foo () yields {
message (hello);
yield;
message (world);
}
void main () {
foo.begin ();
message (vala);
var loop = new MainLoop (null, false);
loop.run ();
}

Re: [Vala] Support for coroutines in Vala
If you need something more flexible then GIO asynchronous functions, look at GNU Pth. http://www.gnu.org/software/pth/ If pth is what you need, I have written a vapi for it. Let me know. Yes please, I am interested ! Basically the only feature of Go I miss in Vala are the Goroutines, i.e. an easy way to achieve concurrency. BTW notice that you did not include the mailing list in your answer. Yes, you are right ! Thank you !

[Vala] [ANNOUNCE] Vala 0.13.1 - Compiler for the GObject type system
We are pleased to announce version 0.13.1 of Vala, a compiler for the GObject type system. Vala 0.13.1 is now available for download at: http://download.gnome.org/sources/vala/0.13/ Changes since 0.13.0 * Many bug fixes and binding updates. Vala is a new 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. More information about Vala is available at http://www.vala-project.org/ Jürg Billeter ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
Re: [Vala] Why the temporary variables in the C code are usefull ?
The compiler can optimize this. Those temp vars are just to make the vala
compiler simpler.. It would be great if vala could do some minor optimization
steps before spitting C. But if you compile with -O2 it shouldnt be something
to worry.

Hi everybody,
Why assignements in Vala make C code with multiples temporary variables ?
It's not very good for the performances...
I read codegen/valaccodeassignmentmodule.vala and I found this:
if (!is_pure_ccode_expression (lhs)) {
/* Assign lhs to temp var to avoid repeating side effect */
var lhs_value_type = assignment.left.value_type.copy ();
string lhs_temp_name = _tmp%d_.printf (next_temp_var_id++);
var lhs_temp = new LocalVariable (lhs_value_type, * + lhs_temp_name);
emit_temp_var (lhs_temp);
ccode.add_assignment (get_variable_cexpression (lhs_temp_name), new
CCodeUnaryExpression (CCodeUnaryOperator.ADDRESS_OF, lhs));
lhs = new CCodeParenthesizedExpression (new CCodeUnaryExpression
(CCodeUnaryOperator.POINTER_INDIRECTION, get_variable_cexpression
(lhs_temp_name)));
}
What are the side effects corrected by the temporary variables ?
