Re: [Vala] vapigen and Autotools problem
Alejandro, Is there a reason to create a .vapi file? Couldn't your vala developers just use the .gir file? AFAIK, that is the preferred method for binding to vala if you are already writing gobject libs. -august. Hi, vala-list. Before anything else, I have to say I'm new to Vala and also to vapigen usage. I've been working on a library which uses GObject and GTK + and is written in C, now other developers are going to use this library to write an application, but they will do it using Vala, so I'm currently binding it using GObjectIntrospecton and vapigen, both integrated with the GNU Autotools. The directory structure of the library is composed by 4 directories, each of which contains an alredy generated .gir file. I've managed to integrate GObjectInstrospection in the project, and right now I'm dealing with vapigen (whose documentation about integration with Autotools doesn't exist, currently). The 4 directories have an horizontal dependency so the .gir of the first one is needed to generate the .gir (and .vapi) of the next one and so on with all of them, all being in the same level of the build tree. To generate the .girs I've used the --include-uninstalled option to include the previously generated .gir file of the project. Now, when the build system tries to run vapigen to generate a .vapi that depends on another part of the library, it fails. The call to vapigen is something like this: $(VAPIGEN) --pkg glib-2.0 --pkg gobject-2.0 --pkg gvn-0.1 -d $(vapidir) --vapidir=$(vapidir) --library foo-0.1 Foo-0.1.gir The .vapi file of the gvn package is alredy generated (and put in the directory specified via the --vapidir option) at this point, as well as the .gir of the current package. And this is the error it produces: error: Package `Gvn-0.1' not found in specified Vala API directories or GObject-Introspection GIR directories I guess it has something to do with the package not being installed, but I couldn't find a way to tell it to vapigen. However that's just a guess, so I don't really know what i'm doing wrong and/or how to solve this. Can anyone help me with it? Thanks in advance!

Re: [Vala] vapigen and Autotools problem
August, I just didn't know that. Reading the documentation and looking at an official gnome project (GDA, that does the same thing I was trying to do) I though it was the only way to bind C to Vala. And the other developers I mentioned are using Vala by the first time, too. If I can do this that way I'll save some time! Can you give me some reference to that method? If you have already created the .gir file and installed it in the proper location (with other gir files), then you should be able to use it directly in vala code. For example, if you are writing a gobject lib called Mylib, you create a Mylib-1.0.gir file and then a typelib file with something like: g-ir-compiler --includedir $(PREFIX)/share/gir-1.0/ Mylib-1.0.gir -o Mylib-1.0.typelib and put the .gir file under $(PREFIX)/share/gir-1.0/ and put the .typelib file under $(PREFIX)/lib/girepository-1.0/ then, vala users _should_ be able to call your api with: using Mylib-1.0; Since you are creating a GObject lib, I _thought_ the preferred method was through .gir and not .vapia. But, I could be wrong. I remember getting advised to do it this way on IRC. Of course, I am writing my gobject C lib in VALA, so that may have been why I was given that advice. If any of this is wrong, I would also love to know the proper methodwith or without autotools. thanks, best, suerte -august. -- http://aug.ment.org GPG: 0A8D 2BC7 243D 57D0 469D 9736 C557 458F 003E 6952 ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list

Re: [Vala] Vala logo symbol voting
Hi Tobias, All, I hope you don't mind me making a suggestion here. I find all of the graphics you've made to be very professional. I really like the wing and definitely prefer the 2 tone graphic over glass effects. I was only wondering if it would be possible to see the wings with another text graphic below it. The vala with the sharp edges kind of turns me off. Vala is more of a rounded and soft word with lots of vowels. It rolls off the tongue. The graphic I see in your logos, however, expresses a lot of consonants and pointedness. To me, the current text graphic contradicts the forgiving and welcoming feel of the vala language. To me, vala takes the snagging edges out of programming. It's a more human and organic language, less machine. Would it be possible to round off the points on the text graphic? I'm not sure it would be better, but I think it would be interesting to see. For sure, it will set other things in the logo out of balance, but it just might fit the wings better. best -august. Tobias Bernard say: Hi Since there were no further comments on the logo drafts, I thought I'd propose to vote on the logo symbol. here http://ubuntuone.com/p/1DBL/'s a revised version of the logo symbol part of my proposal document http://ubuntuone.com/p/1AW8/ (alternative download http://tobias.bluestain.net/wp-content/uploads/2011/08/vala01.pdf ) I don't know how you organize votings here, so I have some questions on that: What is needed to start an official voting? Is there a some kind of a leader who offcially announces votings? Who is allowed to vote and how many people need to vote to take a decision? After thinking a bit more about it, I changed certain poposals, deleted others and added new ones. Of course I tried to always keep your feedback in mind. So here's the changes in detail: 1) Putting the symbol inside a circle for the main logo is a bad idea. In some cases the symbol could be used this way, but as a variant, not as the main one. This is why I deleted all proposals inside a circle. 2) The symbolism of ancient warfare is hard to understand. Probably too hard to be understood instantly by most people, so I put that proposal away too. 3) The simplicity of the first proposal (horizontal wing) was liked by many, so I added a similar symbol with a simple vertical wing. 4) Thanks to XY, I used your idea for proposal 04, however I am still not sure if a) The V is readable b) The wing is recognizable I thought I'd let the community decide this by voting ;) I'm looking forward to hear from you, so the votings can begin. Of course, any kind of feedback is welcome and any changes can be made to the current proposals. kind regards tobias ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list -- --- http://aug.ment.org GPG: 0A8D 2BC7 243D 57D0 469D 9736 C557 458F 003E 6952 signature.asc Description: Digital signature ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list

Re: [Vala] Further speculations on couroutines, generators and threads : Emulating Go's goroutines and channels in Vala
I've been following this thread with interest. I also find the
documentation about async methods in vala to be a little thin. For
example, in the tutorial, the first line of description says:
With asynchronous methods it is possible to do programming without
any blocking.
The following examples in the tutorial are much more enlightening...so
it's not that bad. But, maybe it could be improved.
I always thought async methods:
a) are always single threaded
b) uses the glib runtime scheduler to simulate
multi-processes
c) cannot take advantage of multi-core or multi-processor
computers
Is that correct?
Also, are there any plans to ease multi-core development in Vala?
thanks, best -august.
Actually, this is Luca's code (the coroutine-based generator).
(I am the guilty party to blame for the naive idea to try to add threads to
it : I had the Goroutine/channel concept of Go in mind and was trying to
emulate it by attempting to combine Luca's generator with threads).

Here is a further development of the idea of Luca Bruno about a Vala

(which plays the role of the Go channel form which the result from a
given
thread can be pulled):
To clarify after all the confusion (partly my fault -- sorry):
- Luco's Generator doesn't need threads, and it doesn't need a main
loop either, even though it is using 'async'
- The whole thing runs in a single thread
A few thoughts:
- 'async' is really powerful in Vala, but also quite hard to
understand. (I wish I could find a high-level design document
explaining async in GIO.)
- Its implementation of coroutines doesn't require another stack, it
holds its state in a private data structure. When it does a 'yield'
it returns to the caller, and when it is next given control, it
resumes the previous point of execution using a switch and 'goto'.
- Probably it could all go a lot faster if less housekeeping was going
on, but I haven't seen Go's implementation either, so who knows how
it compares. Anyway, Vala always puts functionality first and
optimisation second, which suits people who want to get the job done
now instead of waiting for the ultimate language to arrive, so that
seems okay.
Attached is a version of Serge's code with all the thread stuff cut
out, which still works.

Re: [Vala] opengl and gtk+-3.0
Is there any way right now to open a GL context up inside of a GTK+3 window using vala? I've been trying to automatically parse the headers glext.h and glxext.h so I could use OpenGL functions that aren't available in the current gl.vapi (anything beyond OpenGL 1.3). So far, I've managed to produce bindings for the functions and the constants defined in both headers. I'm not sure what to do with the types, though. Is there anywhere I can go to find out what all the [IntegerType (rank=9)] stuff means, and how I decide to use rank=9 versus rank=7 or 6, or whatever number strikes my fancy? I've attached my progress so far. There are two python files; each of them parse the header they are named after. Two directories need to be present before either script runs: intermediates and xintermediates. To run the script, type: python vala_glext_header_parser.py debug The scripts produces 4 things: 1. and 2.) A constants.vapi and functions.vapi file either in intermediates or xintermediates, depending on whether the parser is for GL or GLX. 3.) A debug log 4.) A list of the types used in each function printed to the command line. This is so I have an easy-to-reference list of the types used in the .vapi that need binding.

[Vala] vala, libpeas, GIR
Hi there,
I've been playing around with vala, libpeas, and plugins loaded on
the fly through libseed (javascript) and python.
The way you make plugins in libpeas is through extensions. These
can be defined through an interface. It looks something like this:
public interface MyActivatable : Object {
public abstract ScriptableWindow window { get; set; }
public abstract void activate ();
public abstract void deactivate ();
}
Since libpeas doesn't really handle Vala code, I've been trying to
write vala that compiles close to the same C code that libpease
wants.
The above interface works to some extent, but I did
noticed that the GIR file that vala produces is not the same as
what libpeas has. They have a default interface called Activatable
whos GIR file looks like so (section):
field name=activate
callback name=activate
return-value transfer-ownership=none
type name=none c:type=void/
/return-value
parameters
parameter name=activatable transfer-ownership=none
type name=Activatable c:type=PeasActivatable*/
/parameter
/parameters
/callback
/field
The GIr that vala produces looks like this however:
callback name=my_activatable_activate
c:type=my_activatable_activate
return-value transfer-ownership=none
type name=none/
/return-value
/callback
It is missing the field tags altogether. Since they are using some
sort
of automatic means of generating the GIR file, I wonder where these field
statems come from. I was told on the #libpeas IRC that the GIR creation is off
in vala. Any ideas or help on this?
There is something wrong in the GIR that causes all python plugins to
crash when they use MyActivatable instead of the default Activatable from
libpeas.
thanks -august.

Re: [Vala] appsink binding in gstreamer
okay, I received some help from the IRC channel (thanks!) and here is
what I found:
To create the appsink object, you need to use the element factory and
cast it like this:
// not this.sink = AppSink() like you would think.
this.sink = (AppSink)ElementFactory.make (appsink, sink);
then, you can set the signals like so:
this.sink.new_preroll.connect(this.new_preroll);
this.sink.new_buffer.connect(this.new_buf_cb);
my problem now is how to deal with Gst.Buffers. Sorry if my questions
are elementary. I'm trying to learn vala, glib, gst all at once.
In my signal callback for new_buffer, I do this:
private void new_buf_cb( ) {
print(new buffer.\n);
//Gst.Buffer.replace(ref buffer,this.sink.pull_buffer() );
buffer = this.sink.pull_buffer();
this.queue_draw();
}
Can someone tell my why the app crashes when trying to assign the
pull_buffer() to my Buffer buffer?
I also tried to call replace on the buffer, but it won't compile.
Any hints?
chugging along -august.
I was talking with some folks about the faulty appsink bindings in
gstreamer on IRC last night.
I also found this online:

Any answers to those questions?
It seems you can't even create the AppSink object.
Is there another way to create it and set the signals using
ElementFactory ?
thanks -august.

Re: [Vala] valgrind or something similar
thanks for all the tips. Hey August, Am Sonntag, den 26.09.2010, 20:18 +0200 schrieb august: Is there something like a valgrind or method for debugging memory leaks and mismanagement? Something that helped me in real life (tm) was using nemiver and watching the ref_count field of Object derived classes. You need to compile the vala files using the -g flag, to be able to use nemiver (a gdb gui).

[Vala] valgrind or something similar
Hi, I'm new to the reference counting way of glib. I'm also a little worried about the weak and unowned keywords. After reading the docs, I'm still a bit confused. Is there something like a valgrind or method for debugging memory leaks and mismanagement? thanks -august. ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
