[Vala] How to append element to Variant array of tuples?

2012-05-17T19:25:07

Hi!

In my app I use Settings with key defined in schema as follows:

a(sbsyssbyqqqq)

I am able to retreive it with

Variant mykey = settings.get_value("mykey");


The question is:

how can I add an element to end of this array and store that value in
the settings?

It could be interpret as a much more general question:

how to add in Vala an element to existing Variant if VariantType is
array of tuples?


Thank you in advance,

your help will be really appreciated.

Thanks! That's exactlty what I was looking for.

I just mentioned the GIDL beacause I didn't know how to do it, but I 
understad the advantage of putting it on the G-I annotations.

Evan Nemerson — 2012-05-16T19:09:32

GIDL is not the same as GIR (which is the XML format used by GObject
Introspection).  You could use GIR metadata to achieve what you're
after:

        MyObject.object_list type="weak GLib.SList<AnotherObject>"

If you really did mean GIDL you could do something like this:

        MyObject.object_list type_arguments="AnotherObject"

But if you're really using G-I it would be best to add the proper
annotations to your C code so other G-I consumers can take advantage.  I
believe something like this should work:

        /**
         * MyObject:
         * < at >object_list: (element-type AnotherObject): list of objects
         *
         * Description of MyObject.
         */
        typedef struct _MyObject {
          GSList* object_list;
        } MyObject;

[Vala] How to set the type of the elements in a container onbindings.

Alejandro T. Colombini — 2012-05-16T13:28:48

Hello vala-list,
  I'm generating a Vala binding for a C library using vapigen and I've
managed to set the type of the elements by using the GObject
Introspection's "element-type" annotation for both the parameters and
return values of functions, but now I need a way to do the same thing for
the element type of object memebers.

  A simple example of what I want:
public class MyObject : GLib.Object{
    public weak GLib.SList<AnotherObject> object_list;
}

  And this is what I've generated so far:
public class MyObject : GLib.Object{
    public weak GLib.SList<void*> object_list;
}

  I've taken a look at the GIDL metadata and also the GObject
Instrospection documentations, but i've found nothing that suits my needs.
If there's still no way (or will never be) to do this, I guess there's no
problem leaving the element type as "void*" in the generated .vapi files.

Regards, and thanks!

Alex

Re: [Vala] printing int64 value to standard output

Just use string templates:

stdout.printf (< at >"$ts\n");

String templates will always give you the proper format.

i know :) but that's just up to the GLIB library, not the C standard. 
you can use an const string somewhere like:

const string U64FMTd = "%"+uint64.FORMAT_MODIFIER+"d";

But I agree.. glib should provide a format string modifier for this 
instead of providing defines for using them.

Sam Wilson — 2012-05-15T12:43:07

That just looks horrible... Couldn't Vala just compile %lld into the 
proper format on each platform?

[Vala] Floating references

Alberto Mardegan — 2012-05-15T11:21:13

Hi all,
  I have defined (in C) a GObject subclass which defines a virtual
method which should create a new GtkWidget:

========
/**
 * ap_application_plugin_build_widget:
 * < at >self: the #ApApplicationPlugin.
 *
 * Returns: (transfer floating): a #GtkWidget, or %NULL.
 */
GtkWidget *
ap_application_plugin_build_widget (ApApplicationPlugin *self)
{
    g_return_val_if_fail (AP_IS_APPLICATION_PLUGIN (self), NULL);
    return AP_APPLICATION_PLUGIN_GET_CLASS (self)->build_widget (self);
}
========

Then, I have a subclass of ApApplicationPlugin, written in Vala, which
should reimplement the build_widget() virtual method. But is it possible
to write it so that it returns a floating reference?
I tried:

========
    [ CCode ( returns_floating_reference = true ) ]
    public override unowned Gtk.Widget build_widget () {
        return new Gtk.Label ("Hello world!");
    }
========

but the code doesn't compile: "Return value transfers ownership but
method return type hasn't been declared to transfer ownership". If I

%lld is not portable. your code will not work on windows.

the portable way is:

void main() {
         uint64 ts = 123;
         stdout.printf ("%"+uint64.FORMAT_MODIFIER;+"d\n", ts);
}

This is independent of the Vala version. GLib 2.32 no longer prints
debug messages by default. Set G_MESSAGES_DEBUG=all in the environment
to get the behavior of earlier GLib versions.

Hi Edwin,

you may find it, and if you work on Ubuntu/Win7, to open the .rpm files
from windows I use 7-Zip (also works with .deb).  I just found that list by
googling hard but I haven't time to test them yet, so I you make any
progress please share your findings :)

Anyway I myself as I think you're, I'm trying to get a minimal stack of

I will love if someone has experience using libseed with gtk3 in Win7 and
if you or any on this list can help me a little bit since I'm pretty new on
Vala and free-software developments in general.

Currently for the crossbuilding part with Vala I'm using cmake macros with

I inadvertently left the list off this reply.. However, MULTILINE was still

Would you use string.split?
slice index notation [-1] is  like a bit strange... (ex: footer[-1]

int main () {
  string the_string = """
    start text line 1
    start text line 2
    %tag:keytag%
    the content betwen tag line1
    %endtag%
    the end line 1
    the end line 2
    """;

  Regex r = /\s*(?P<start>.*)\s*%(?P<key>.*)%\s*(?P<content>.*)\s*%(?P<ekey>.*)%\s*(?P<end>.*)/;
  MatchInfo info;
  if(r.match(the_string, 0, out info)) {
    var s = info.fetch_named("start");
    var key = info.fetch_named("key");
    var cont = info.fetch_named("content");
    var ekey = info.fetch_named("ekey");
    var e = info.fetch_named("end");

    print("%s\n",s); // start text line 2
    print("%s\n",key); // tag:keytag
    print("%s\n",cont); // the content betwen tag line1
    print("%s\n",ekey); // endtag
    print("%s\n",e); // the end line 1

    var header = the_string.split("%"+key+"%");
    var footer = the_string.split("%"+ekey+
