As a matter of fact there are many languages you can use gobject in. But it doesn't necessarily feel right because you're supposed to follow the patterns of the language (and naturally also want to do so) but you have to follow GLibs pattern. About ten years earlier i started programming against Gtk in python which was one of the more convenient ways to do so at the time (before i tried coding Gtk in perl and C). Oh boy. It was such a hazzle until I figured out which of the mechanics belonged to python and wich ones belonged to glib and even that there is a difference between python threads and glib threads. Each language brings their own means (stdlib) of interfacing with system functionality and GLib brings it's own. This will allways be confusing in any language that does not follow the same principles as Vala and Genie. I've read that you can use Rust without a standard library. Maybe this will actually make it suitable for GObject code. I know i repeat myself, but i am stoked to see the results. ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list

There are many languages that are also fun when it comes to programming against the Glib based library stack. The more interesting part is: will there ever be a language that makes it also as convenient to write gobject-introspectable libraries. That is the one true thing that one can do very conveniently with Vala but with no other ecosystem can do yet. I hope the rust-gnomies care about that too and not only on using the bindings. It's an integral part of integrating well into the gnome library ecosystem imho.

I want to extend the functionality of the library classes. Therefore I should inherit from them. As it seems to me this is a valid OOP-style endeavour.

[Vala] Invalid cast Warnings
Hi, fellow valaists. At the moment I deal with a series of warnings like these: (process:3325): GLib-GObject-WARNING **: invalid cast from 'OParlSystem' to 'System' I have a library that exposes a set of classes. I extend each of those classes in the application that uses said library. When I fetch a new Object of one of those library-classes, I downcast it to the matching class of the application layer code. I compiled a minimum example to trigger the issue here: https://0bin.net/paste/J0sgx2b2NJp6lTj8#QBfz-GUhWagsfGsF7nUqEn/8XneAiL9NhYNIdo8GRt6 Note that the deriving application-layer class System is entirely empty and only inherits from the library-level class. Why is this considered an invalid cast? Thanks in advance, Grindhold ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list

[Vala] VAPI-Bindings to obscure c-types.
Hi there. First of all, sorry for the bad subject-line, but I'm really missing the words to describe this in a concise manner. As some of you know, I am playing with writing a GLib wrapper for libode6. I've come across another problem that I don't think has been documented on this mailinglist or elsewhere yet: In libode's code, there is a type called dReal. Depending on some compiler flags, dReal might be a double or a float: #if defined(dSINGLE) typedef float dReal; #ifdef dDOUBLE #error You can only #define dSINGLE or dDOUBLE, not both. #endif /* dDOUBLE */ #elif defined(dDOUBLE) typedef double dReal; #else #error You must #define dSINGLE or dDOUBLE #endif The library then uses dReal in various method signatures that I have to bind against. Is there any possibility to cover this in vala? I can never know which distribution sets libode's compiler flags in which way, so I fear my VAPI would break on some systems. Help's very appreciated. Yours, Grindhold ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
[Vala] Vapi bindings and a weird C-pattern
Hi, Guys
I want to write VAPI bindings for liborient [0].
While analyzing the C-code i came across the functions which turned out
to work in a somewhat unexpected way.
Usually one has some struct, methods to create and free the struct and a
set of methods that operate on that struct. Such code can be converted
to VAPI bindings in a straightforward way.
However liborient keeps managing stuff like this:
- One struct to represent a handle
- One struct to represent a connection
- A set of methods which operate on _both_ of the previously mentioned
structs.
A typical method-definition looks like this:
long o_bin_dataclustercount(orientdb *o, orientdb_con *c, struct timeval
*timeout, int nonblocking, short clusternumber);
In Vala I'd like to use the lib like this:
var handle = new OrientDB();
var connection = handle.connect("foo","bar");
connection.dataclustercount(sometimeval, 1, 1);
Under the given circumstances I have the feeling that the best thing one
can achieve is something like this:
var handle = new OrientDB();
var connection = Connection.connect(handle, "foo", "bar")
handle.dataclustercount(connection, sometimeval, 1, 1);
Am I right? Is there any possibility to cover this C-Pattern?
Second question: The library imports at some point and uses
the timeval definition from in there in method signatures. How can i
write equivalent Vala Types to write Vala signatures for them?
Thanks in Advance and a nice evening,
grindhold

[Vala] Mixing C with vala
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi guys. I want to use Vala together with C, in order to do some lowlevel manual memory management stuff in a certain subsystem of my program. At first i tried writing g-object boilerplate-code myself, but it was a bit cumbersome, so i decided to write a class in vala and let the vala compiler generate the boilerplate-code for me. (I obtained the c file via -C and the headerfile via -h) currently i have 4 files involved: main.vala nsp-page.c nsp-page.h nsp.vapi main.vala has a simple main-method and creates a Nsp.Page. nsp-page.c and nsp-page.h contain the gobject-code for the Nsp.Page class. nsp.vapi describes the Nsp.Page-class towards the vala compiler. I try to compile everything with $ valac -X -I. --vapidir . --pkg nsp main.vala nsp-page.c Now the following problem arises: main.vala.c:(.text+0x8b): undefined reference to `nsp_page_unref' Of course, the C-code generated from main.vala tries to unreference the generated Page-object. This method does not exist anywhere. When i write Nsp.Page as regular vala-class, main.c tries to derefence the Page-object via g_object_unref() instead of some class-specific method that doesn't exist. What am I doing wrong here?

Re: [Vala] Need some feedback for Valum, a web micro-framework!
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi, Gillaume I discovered valum in the trending projects list of github a few months ago. The first thought was "oh wow, i could write my future web backends in Vala; how cool is that?" directly followed by the remembrance of how painful it is to parse and generate JSON in vala when compared to Go or to Python. To be honest, this is the only thing that keeps me from giving valum a try. Is there some way of conveniently marshalling/unmarshalling JSON in Vala?

I am thrilled to see the results. But, as this is loosely related to Vala in general i'll ask right here: Where do you see the benefits of autotools over cmake in a vala-project? I know that the GNOME project requires its official sub-projects to use autotools als buildsystem and i know that debian packages is most simple when the source tarball uses autotools because one can leave the debian/rules-file as is. But does this really compensate for the time-costs of learning and using the (in my personal view) highly unintuitive autotools? Is there any technical aspect i am missing here?

(Do you need help?) If you mean logic digarams as in "i have nodes that emit logical ONEs and ZEROs, i have nodes that represent logic gates like AND OR XOR NOT e.t.c and i have nodes that output the results", then yes. of course you can write logic diagrams with it. Of course you have to implement your own Nodes for this, but this is no problem at all since you can inherit from GtkFlow.Node as baseclass and implement your logic on top of it. See the example calculator.py in the examples folder. Using cmake has a simple reason: I spend two days trying to use autotools in one of my vala projects and gave up frustratedly with no mentionable result. Then i tried cmake and got a vala project up and running in one night. I am very happy with it and continued to use it for other projects. Currently I see no necessity to switch, but if you want to do it and maintain it, please do and send a pull request. To be honest, i am a bit curious what i did wrong and to see a correct solution how to build such a project with autotools. If you try the port, please be aware that I created some cmake logic to detect if a system has the libgee-1.0 or libgee-0.8-package installed and sets the compilerflags accordingly. This is necessary because of the unlucky decision of the gee-developers to do a backwards version-number-change from 1.0 to 0.8. On debian jessie there are still libgee-1.0-packages around. Without that logic it would be impossible to build on debian older than stretch (testing).

[Vala] Flowgraphs for Gtk in Vala
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi there! I wanted to introduce you to a project that has been on my "to-do"-stack for a long time. Now it grew to be somewhat presentable. Meet our very own Blender-Node-Editor-like flowgraph library for Gtk3: https://github.com/grindhold/libgtkflow GtkFlow gives you a new Widget, the GtkFlow.NodeView you can add nodes to this view that have inputs and outputs (so called sinks and sources respectively). These Nodes and the connections between them can be arranged by the user by dragging and dropping. It provides an easy way for users to communicate to a program how things interact and how things are connected. If you develop UI (especially for GNOME-related stuff), please let yourself be inspired how Flowgraphs could enhance your UI-concept. Some usecases i thought about are: - A GUI for GStreamer that you can build and export your GStreamer pipelines from/to - UI Replacement for GNURadio's Flowgraph implementation - Video Compositing for PiTiVi I am eager to hear about your thoughts of possible usecases and especially for feedback about the library itself. If anyone can use it, i'd also be happy about helpers that engage in pushing the project further. Yours, Grindhold [I posted the same email to gtk-l...@gnome.org .

[Vala] conversion segfault
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hello, fellow Valaists
I have the following example code which segfaults:
public int main(string[] argv){
stdout.printf("hello world\n");
uint64 test = 1;
string x = "foobar"+(string)test;
stdout.printf(x+"\n");
return 0;
}
compiled with my valac 0.26.1, the result segfaults in line 4.
I can't imagine, this is intended behaviour.
Of course, the proper way to go for line 4 would be something like
string x = "foobar%lld".printf(test);
Nevertheless i wonder, why the code segfaults, shouldn't there rather
be a type conversion error at compile time?
Sorry, i don't have a more recent 0.27 or 0.26.2 compiler at hand.
TIA, Grindhold

[Vala] DBus generated code: Missing error Field
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi, Vala-Guys
I tried to fiddle around with some DBus stuff and some strange
behaviour hit me right in my face when i executed make.
I have an interface like this:
[DBus (name = "de.grindhold.alaia")]
interface AlaiaMessenger : Object {
public abstract bool needs_direct_input ();
}
And the Vala-Compiler (0.26.1) creates the following function when
translating to C:
http://pastie.org/private/vgctn74omjldgey0scpbvq
As you can see, somewhere in the declaration section there should be
an GError* error=NULL; somewhere, but it isn't there.
If i edit the C-code manually and put in the line, it compiles through
as nothing would've been wrong.
Is this a known bug? Am i missing something?
Thanks in advance,
Grindhold

[Vala] Nostril / Are you my mommy?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello Vala folks. I want to introduce you to a small project written in Vala. It's name is nostril and it's purpose is to help people inspect HTTP-traffic in an easy and straight-forward GNOMEish way. Nostril acts as a proxy using libsoup and is simply plugged between the application that generates HTTP-traffic and the target. I started writing the program about a year ago until it was able to perform it's most basic tasks, and then i abandoned it due to a lack of time. I assumed that no one else would show interest in the project anyway but from time to time people write to me that they use it and think it's cool, some of whom i know, some of whom are randomly from the internet. So maybe i was wrong and there is some public interest indeed. This is why I decided to bring this to a broader audience, and I think the Vala-ML ist a good point to start. As always there is good news and bad news. Bad news first: I still don't have time to spend on this particular project. Good news: nostril is still a very small project. There is now huge codebase. There is only about five files with an overseeable amount of code in it. There are still a lot of easy-to-fix-bugs and easy-to-implement-features to be done. Nostril seems to be the perfect opportunity for people who want to start at hacking on a cool and useful project in vala and GTK. Do you want to adopt a nostril? Then wait no longer and become a core contributor :) You find nostril in https://github.com/grindhold/nostril Even if you don't want to adopt nostril, feedback, criticism, further ideas, thoughts and stars are appreciated.

Re: [Vala] Gtk TreeView emits a beep ...
> I'm trapped the "release key" event but for certain keys, treeview emits a > beep (left or right arrow, del keys). > > How can I remove this "beep" ? Ohai, Raum. I cannot reproduce the beep with the sample you provided. On some systems, the TreeView emits beeps, when it cannot do what the user commands it to, for example if you press [Arrow Up] and there is no row above the current row, so the move-one-row-higher action cannot be completed properly. I had this behaviour on my old Laptops in Gtk-Applications like Pidgin and others. I never really considered the beeping a problem, but it stopped when i reinstalled the OS at some point. So i think, that this is a configuration problem.

[Vala] Bug with cleared Gee.ArrayList
Hi, fellow vala-people. My project "nostril" is growing well. But again i ran into a bug that i don't know how to fix. I offer an "clear list"-feature. Which empties an ArrayList as in [0] If i already selected an entry in the list for viewing it in detail, the program crashes with an error like this: ERROR:arraylist.c:518:gee_array_list_real_get: assertion failed: (_tmp1_ < _tmp2_) Using a search-engine on that errormessage was not very effective. My first thought was, that it happens because something that should be rendered hits an empty or invalid reference. But according to my debugging output the error happens _after_ the GUI-renderfunction passed through. More Strange: The User can also delete a selection of list-entries my multi-selection. The function that does that takes a list of Entry-IDs and processes them as in [1]. This works. I already tried to delete every entry on its own like in [1] instead of using the clear()-Method of the ArrayList. In this case the error still occurs. The full code can still be cloned an seen here [2] I use valac-0.22 Hope someone can bring some light into the darkness here.

Problem solved. I mistook model.get() for model.get_value()

The lifetime of the SessionAsync ended, when it left the scope of the closure, this triggers the real_cancel_message-method on all queued messages through some kind of destructor.

Perhaps its vala+libsoup > interaction because I rarely have problems with closure. I'm afraid, but this means to me that i am not able to develop my tool in Vala anymore until this issue is fixed. A blocking proxy is no option for a tool that me or anyone wants to use in production. Of course i would like to help the Vala community by reporting this bug. But i don't know what to write, since this is a pretty special issue and we basically have no clue what could possibly cause it. How should i write my bug-report? As both Gtk and Soup are GObject-based libraries, I will try to write an as-exact-as-possible replica of my Vala code in Python3 with GObject-introspection and see if the same problems occur there.

Re: [Vala] libsoup Session.Async does not send stuff
> Have you tried running from command line and > see what those printfs have to say? My debugging output says: Status Code: 1 Message length: 0 Content-type: (null) It does not matter which file i try to get from the server, it always delivers the same output. I am currently reading the source of libsoup and try to understand what's happening. I furtherly also thought of doing the asynchronous handling by using Idle.add() of GLib. But that should theoretically make no difference as the libsoup acts inside Gtk's mainloop anyway. Is this assumption correct?

I tried it, but it did not do the trick, i also tried to compile the code with the newest vala-compiler (0.22), but it did not make a difference (i used 0.16 before). Could the Problem be the two nested asynchronous contexts? I am not exactly sure how those closures work.

[Vala] libsoup Session.Async does not send stuff
Greetings, people of Vala I try to build an HTTP proxy with libsoup underneath. I realized it like [0], and this solution works well. Unfortunately, as the calls to the target hosts are done synchronously, it's blocking the gui in the time that calls are done. Besides as a result, the proxy also is awfully slow. I tried to fix that using [1]. I substituted the Soup.SessionSync and used a Soup.SessionAsync instead. Further i do not send the method by using .send_message(SoupMessage m) but using .queue_message(SoupMessage m, callback). The outcome of that also is pretty unexpected. The messages are returned to the browser with a status code of 1 and an observation with wireshark revealed, that the packages are never being sent to the target host. Why is that? Most interestingly: The Async-Example from the documentation works with my Vala-Setup. I use Vala 0.16.1 Regards, adn TIA, grindhold [0] Proxy-Code as used in nostril currently: https://github.com/grindhold/nostril/blob/master/src/proxy.vala [1] Modified default_handler with async stuff in it: http://pastebin.com/wgFUpmFk signature.asc Description: This is a digitally signed message part ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
[Vala] Retrieve Row ID from Gtk.TreeView
Hi guys,
I am fairly new to Vala and decided to learn it by implementing a tool,
which i always wished for in the GNOME desktop environment but never
found a solution that pleased me: A HTTP debugging proxy in Gtk.
I am familiar with Gtk, because i used it excessively in Python, which
is, why i am pretty clueless about the following function, that does not
behave as i would expect it to do.
I try to use the following code to retrieve a row ID which is stored in
the second column of my list_store. It always returns 0 with an error
message, that val does not hold int, what i dont understand because the
column value is gint (set in glade) and i set an int value to this
line.
[CCode (instance_pos = -1)]
public void selected_request(Gtk.TreeView source){
Gtk.TreeSelection sel = source.get_selection();
Gtk.TreeIter selected;
Gtk.TreeModel model;
sel.get_selected(out model, out selected);
model = source.get_model();
GLib.Value val;
model.get(selected, 1, out val);
this.id_currently_displayed = val.get_int();
this.render();
}
The full code can be seen at http://github.com/grindhold/nostril
I have another question, too. I assume that this mailinglist is "one
question -> one thread"-organized, so I open another Thread for that.
(please tell me if your social protocl dictates otherwise)
Regards and thanks in advance for your help.
Grindhold
P.S.: Vala is a great and very underrated language. I am glad, i
discovered it.
