Re: [Vala] C# developer, newbie question

I believe it's because the string produced in your first assignment to strState is the C transformed enum value which concatenates the type and value with an "_". It does this to map the nested name space of Vala enums into the flat C name space. You would need to remove the type + "_" from the

I find Anjuta to be usable, good for setting up projects and ok for debugging (you have to have some understanding of the Gobject structure to use it though, and "this." is "self->"). Anjuta ctags understands Vala, so go to declaration works, etc. Symbol completion is pretty good, and generally

[Vala] Catch divide by zero

Is there a simple way to catch and propagate a divide by zero error in Vala? In C I can use a setjmp to define a catch point, and then do a suitable jongjmp from a signal handler. However this mechanism doesn't appear to be available to the Vala programmer, so what can be done? Regards, Andrew

[Vala] Socket source

Hi, After 0.30, the socket create source function changed from returning a SocketSource to returning a GLib.Source. Now, for the correct operation of the socket callback, the returned object must be a SocketSource, so: - Is the implementation still the same, and presumably if so it is safe

You can access them as strings: Foo.ELEMENT.to_string() (or any Foo-typed expression). The default result may be a bit clunky, but very useful nevertheless. Add you own to_string if you want to get fancy. On Thu, Sep 1, 2016 at 3:51 AM, rastersoft wrote: > El 31/08/16 a

Hi gentlemen, If I have the following code, or similar: void main (string[] args) { uint ui = 2; int i = -3; if (i < ui) { stdout.printf("Comparison works\n"); } } No output is produced. Given Vala is generally very good at warning about type mismatches, or correctly doing an

[Vala] string.to_long vs long.parse
