I have been using Nicolas's Nicoedit but I have previously used geany and become accustomed to it's short-cuts for indentation etc... it may be chunckier but I am not good with different.

The geany guys have made my day with syntax highlighting for genie!! In case others wish to know...

Hi Mobeus and other,

In fact you can close the file if you want !
Use pointer !

Code:

 [indent=4]

init
    fn : string = "/tmp/test.sh"
    doit(fn)
   
def doit (filename : string)
    fp0 : FileStream* = FileStream.open (filename, "w")
    fp1 : unowned FileStream = fp0
    fp1.puts ("ls /root")
    fp1.flush()
    delete(fp0) // Close the file !
    FileUtils.chmod (filename, 0750)
    try
        Process.spawn_command_line_async (filename)
    except ex : GLib.Error
        print ("%s", ex.message)


I hope this is correct.

See you,
Nicolas.

@all - improved gtkbuilder example
This one works with the default values from glade3 and uses a user input gtkbuilder xml file (from glade)

//save as gtkbox.vala
Code:
using Gtk;

int main (string[] args) {     
    Gtk.init (ref args);

    try {
        var builder = new Builder ();
        builder.add_from_file (args[1]);
        builder.connect_signals (null);
        var window = builder.get_object ("window1") as Window;
        window.destroy.connect(Gtk.main_quit);
        window.show_all ();
        Gtk.main ();
    } catch (Error e) {
        stderr.printf ("Could not load UI: %s\n", e.message);
        return 1;
    }
    return 0;
}



to build:
valac --pkg gtk+-2.0 --pkg gmodule-2.0 gtkbox.vala

to run:
./gtkbox anygtkbuilderui

Note: glade sets the gtkwindow id to window1 - don't change it
... may change it later to require the id to be the same as the basename of the ui file (if I can figure out basename in vala)

PostPosted: Sun 05 Dec 2010, 15:17    Post subject: how to connect signals?  
Many of the existing code examples contain depricated code by connecting Signals.
i.E.
Code:
destroy += Gtk.main_quit


is replaced by
Code:
destroy.connect(Gtk.main_quit)


but i didn't find out how to repace the following Syntax:

Code:

button.clicked += def (btn)
   title = "Hello World"
   btn.label = "Hello World"


Has anyone a Idea how to do this?

/* Build with valac --pkg gtk+-2.0 hello-gtk.gs
valac --version 0.7.4 */
uses
Gtk

init
Gtk.init(ref args)
var test = new TestWindow()
test.show_all()
Gtk.main()

class TestWindow : Window

button : Button

init
title = "Test Window"
default_height = 250
default_width = 250
window_position = WindowPosition.CENTER
destroy.connect (Gtk.main_quit)
button = new Button.with_label("Click Me")
button.clicked.connect (btnclick)
add(button)

def btnclick ()
title = "you have clicked"
button.label = "Hello World"

I made a simple HTTP wrapper for gene and almost lost it when some data accidentally got deleted from my hard drive. I decided to dedicate a section on my site to source code, so if anyone wants to look at it here it is. If I make anything else that I think might serve a use to others I will upload it here also.

Liboicl - should those addresses still work? The ftp asks for a user name and password, and the http just gives an error page...

I am considering making this feature request:

"Change the name of vala to "Pencil"
...It just seems more correct...
    User: What did you write it in?
    Me: Pencil
    User: Oh.... so that's why you need to keep rewriting it - it must be fading
    Me: Something like that.

Warning: convert your vala code to C before you upgrade to a new version of vala (in other words make an "ink" copy)

Subject description: Should I make an Automated Universal Installer		  
The existing Universal Installer asks questions it doesn't need to.
For example it gives a list of all the possible installation media when it could detect what you have available instead.
So do you think i should create AUI and do you have any other suggestions.
P.S I would like to write it in Genie code.

My server was taken down. If anyone has a suggestion of a good cheap host I can have the code back up quickly.

Go for it
My suggestion is an easy toggle for the
'Do not run as root' drones,
so they can they switch between
root and password restricted user status

That's all very well lobster, but Puppy needs to be set up first so that he can run as a restricted user.

Code:
rxvt -e su spot

will allow you to run as user spot

Kirk in fatdog also ensures downloads
to a download folder,
that might be a good program toggle

Another useful program might allow one to edit the menus
or use various preselects, such beginner, simple, advanced Cool

Latest version uploaded:
Pcreole 1.0.2

Changes:
- The "t" button now opens both an rxvt and a rox filemanager window at the selected directory.
- many extra commandlines (and some fixed old ones) with brief explanation header added to the Combo box list
- find more commands to add yourself from, for example, http://www.commandlinefu.com/
----

Note that Pcreole, with a suitable commandline etc, is also designed to provide a (unsophisticated) programming environment for compiling (e.g. with gcc, Vala, Genie etc)
