I am trying to get genie to generate some sound.
Is this possible? Rather than play a wav I was wondering about generating a beep?

Not sure where to start?


I have no speaker attached, so cannot test it.
Try:
Code:
stdout.printf("\7")
stdout.flush()


This should do the same as typing this in a console:
echo -en "\7"
According to google "beep linux shell", this is the code to generate a beep.

For wav, yes, gstreamer, but it is not in Puppy by default.
You might use one of Puppys tools.

Code:
[indent=4]

def exec(thecmd : string)
    try
        Process.spawn_command_line_async(thecmd)
    except ex : GLib.Error
        print("%s", "exec failed!")

init

 
    exec("wavplay /usr/share/audio/2barks.wav")

//end

works!
many thanks guys Cool

I am trying to put some building blocks together for a project, that I hope to begin this weekend.
(fear not - I will not be doing the coding
- have a real coder for that)

A simple Puppy game.
The next piece of code is to open a 'window'
and draw a circle in it.
Any clues? (remember I am clueless)

PS.
I am using the latest genie text editor compiled by Ttuuxxx to compile and build the code - very nice.

Is NicoEdit heading towards this option to
compile and build code?

for grafics, you might use the Cairo library.

It also is possible using Gtk/Gdk itself, for example the Gtkbasic Analogclock was written like that.

But for Genie/Vala, I actually just know one example, that is based on Cairo.
http://www.murga-linux.com/puppy/viewtopic.php?p=292901#292901

See the example from Mymas and my reply.

Circle: Instead of
ctx.show_text ('Hello, World')
you could look at the
http://valadoc.org/?pkg=cairo
http://valadoc.org/?pkg=cairo&element=Cairo.Context
http://valadoc.org/?pkg=cairo&element=Cairo.Context.arc

So something like
ctx.arc(100,100, ... )

Is it challenging to compile Vala 0.7.4?

I notice that NicoEdit has that as a requirement but I'm yet to find a .deb distribution of it anywhere.

Regards
Caleb

Hi,

Version 2 beta 3 !

News:
Search in text is now fully working
Added "signal for search and gotoline, when you type text to search or line to go, just press enter ! "
Added "F11 shortcut for fullscreen/unfullscreen"
Added "Auto-indent, Indent-on-Tab, Indent-Width"
Added "When you click on change font, the font dialog remember the last selection"
Deleted the "big" search box !

Nicolas.
Cool.

Bugs:
    Pressing Control-f does not work when in full-screen
    Using undo when there is nothing to undo clears the file (or is this a feature?)
    The line/column display in the statusbar doesn't update when the cursor is moved around, only when you type something


Suggestions:
    Have the find box automatically jump back to the top when the bottom has been reached (maybe make this optional for the people who dislike it)
    Add a keyboard shortcut for 'find-next' to be used when the cursor is not in the find-box (like F3 in Firefox or Control-g in Geany)
    Close the find-bar if the user presses Esc while the cursor is inside it
    Have Control-f put the cursor into the find-bar's box
    Add a feature like "softtabs" in Vim, where if you use spaces for tabs and the cursor is at a tabstop, pressing backspace will delete the number of spaces that you use for tabs (assuming there are that many spaces behind it to delete - if there is text in the way, function normally instead). This would probably need to be optional.


Observation for those who don't know this:
    When the cursor is inside the find-bar, it can be put back into the main area by pressing the up key



Those are just suggestions. Please don't feel obligated to implement them. I already have Vim and don't intend to use much else anytime soon. I just thought I'd mention some ideas. Smile

sorry to be coming in late

looking forward to testing

Hi Joe,

I'm using:
Gtk 2.16.1
Glib 2.20.1
Gtksourceview2 2.6.2 (but i think a newer version is better for genie syntax hilighting)
Pango 1.24.0
Cairo 1.8.6

Nicolas.
