Lobster, be certain to activate "view - bottom view".
That displays the internal console, where the messages from your program are printed.


Thank goodness there are smart people guiding the idiot cructaceans . . .
That did it
Works fine Very Happy

Mark are you more inclined to use Vala
because of your java experience? Cool
I am more inclined to Genie . . .

The reason I ask is because if we have a list
of reserved words for Genie that might be a way for the programmers of
Valide to provide some colour coding
and support both languages?
I believe this exists for Vala but not Genie?

No, I like both.
Vala is more like C/Java, Genie like Basic.

I concentrate on vala, because there is more documentation.
So to get startet, I tried vala, then I can try to port the programs to Genie.

Concerning Syntax-highlighting, I think further modifications of the IDE would be required.
I hesitate to mess around in foreign code.
I would suggest, that you contact the author:
http://code.google.com/p/valide/
http://valaide.blogspot.com/

I think it would be better, if you do it, not me.
I already have this "tunnel-view", so would not see requirements for beginners.
So I think you could suggest more "basic" issues, that would have priority at the current state.
---------------------------------------------------
I attach a new example.
This was a "pain in the *", it took a whole day, to find out, how it works.

It is an extended version of the Glade example now written in Genie.
During compilation you get a warning, but you can ignore it.

I added two helper functions, that allow to set values like a buttontext on the Window, that was generated from the gladesample.glade.

If you use other widgets, you had to add corresponding helperfunctions, but they are very simple.
Make a copy of "get_button", and rename "button" to the type of widget, that you need to access.

Unlike C, vala/genie does not allow Widget-conversion.
This will not work:

Code:
GtkWidget *w;
w=glade_xml_get_widget(xml, "button1");
Gtk_button_set_label(GTK_BUTTON(w) , "testtext");


This is not possible:
GTK_BUTTON(w)

The new helperfunctions work around that issue.

OK I am in a strange place (quite usual for me)
I could not drag .gs files into an editor or open them in a text editor

the only command that worked was
Code:
cat v1.gs
from the terminal . . .

So I am in the process of reinstalling genie
and getting it to work from the command line again . . .
in a new run of Puppy (setting puppy up was easy)

I have no idea what or how I broke things . . .
downloading every stray pet under the sun and
wearing no tin hat might be part of it Wink

Is anyone else playing with genie?
What ya doing? Smile

Hey Mark
I wrote to the author:

Is Genie support and colour syntax coding planned for future valide releases?

with a link to this forum
and have got 'Geni(e)de' working again

Now to try your GTK example . ..

The examples now also work in Windows.

They require to add some files to a standard Vala installation, and to add options to the compiler.

Everything is here:

see "readme.txt" for details.

Vala or Valide is making my system unstable (running 4.2 rc3)

Ideally I would recompile for 4.2 or wait for an update of Vala or use 4.12
The main problem is not being able to edit text files.
They seem to lock.

I may have wait until 4.2 final is released this week
and take it from there . . .
or maybe go straight to woof alpha 3 hopefully with added Vala

It is good to be on the cutting edge but I am being shredded . . .

Hopefully more intrepid programmers will join us soon Wink

Lob, first thanks for writing to the author.

Second, I'm very surprised, about your issues.
I can not imagine, what causes this, as vala and valaide do not modify anything in the system.

Do your problems remain after a reboot?
When exactly do they begin?
I would compile an example in console.
Then try the IDE.

Mark

No problem Very Happy
This is what Nicolas has written back

Hello,

I have planned Genie support for Val(a)IDE.

Currently I work on auto completion, after this I think I will work on
genie support.


So Genie support is coming.

not good.

I install nvidia support
and flash 10 Beta
then Vala
then Valide
Valide is working
but I need to access files
Text editing is basic and I get a lock up
- I can not open .gs as text files
Rebooting does not help

The problem is Mark
Any level of programming is quite hard for me
Takes a lot of concentration
If the base OS is doing odd stuff
then obviously I become distracted.

Vala and Genie are far too important to let
Lobsterian glitches slow it down.
The difficulties seem to occur when valide is installed

Because it has a file manager this makes me suspect Valide
is taking some liberties.

What I will do is work without it and see what happens.

Need to set up my system again Smile

Puppy has Vala
and valour

What I have done so far is run 4.2 rc3 and not tweaked Deep Thought- run in Icewm etc
I have been running vala/genie from the command line all yesterday without incident

I have simplified my IMT program
and trying different code
So far . . . (does not quite work incidentally)

Code:
// Infinite Monkey Theorem
// Lobster March 2009
// myLine = myLine.concat(myChars[GLib.Random.int_range(0,myChars.length)])

init
   a:int
   myChars:array of string = {" ", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}
   myText:string = "i"
   myLine:string = ""
   i:int = 0
   while i<10
      a = GLib.Random.int_range(0,27)
      if myChars[a] is not "i" do continue
      if myChars[a] is not "n" do continue
      print("%d",a)
      print(myChars[a])
      if myChars[a] is "n" do break


Do you know how to use 'Print' continuously rather than with a line break?
Shadow did it here:

Code:
// myLine = myLine.concat(myChars[GLib.Random.int_range(0,myChars.length)])


however that is too hard for me to work out why it works . . . Cool

Anyway just to let you know how I am getting on Smile

Code:
  stdout.printf("test")
  stdout.printf("test")
  stdout.printf("ok\n")
  stdout.flush()


Without "\n", no linefeed is printed.
stdout is printing to a buffer, so you finally in the end have to print a "\n", and you have to "flush" to be sure, it becomes visible.

The long line you mentioned also can be written like this:

Code:
[indent=2]

init

  //-- define the random characters --
  myChars:array of string = {" ", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}


  //-- fill the line with a word --
  var myLine = "testline"
 
  print ("%s" , myLine)


  //-- this is like the long line with print statements included

  //-- calculate the allowed random numbers --
  var thelength = myChars.length

  //-- create a random number --
  var randomvalue = Random.int_range(0,thelength)

  //-- get a random character --
  var randomcharacter = myChars[randomvalue]

  print ("%s" , randomcharacter)

  //-- add the character to the line --
  var alltogether = myLine.concat(randomcharacter)

  print ("%s" , alltogether)
 
 


Notes:
I simplified the code.
Instead of:
Code:
myLine:string = "testline"

you can use:
Code:
var myLine = "testline"


And "GLib." can be ommited, as this library is always loaded.
So instead of:
Code:
var randomvalue = GLib.Random.int_range(0,thelength)

we can use:
Code:
var randomvalue = Random.int_range(0,thelength)

I am not certain, what your program shall do, maybe this is working:

Code:
[indent=2]

init
 

  myChars:array of string = {" ", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}

  var a = 0
  while true
 
    a = Random.int_range(0,27)
    //print("%d",a)
   
    if myChars[a] is not "i" do
      if myChars[a] is not "n" do
        stdout.printf("%d%s ",a, myChars[a])

    if myChars[a] is "n" do
      //stdout.printf("%d%s ",a, myChars[a])
      break
 
   stdout.printf("\n")
   stdout.flush()
       

     


It will print random characters.
It will never print "i".
It stops, when "n" is the random character (it will not be printed).

Mark - many thanks for you help
My program is an implementation of the
infinite monkey theorem
http://en.wikipedia.org/wiki/Infinite_monkey_theorem

It randomly creates text and then looks for specific readable text
in this case it is looking for:
in the beginning god created the heaven and earth

A quantum computer would find the whole of the Bible in an instant
What computing power we have presently takes a lot longer . . .

Quote:
The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare


. . . anyway gonna look at your code now . . .

Incidentally I am editing from Geany with code set as shell script and the colour coding looks OK Smile

Yes Very Happy I have added the support for Genie: http://valaide.blogspot.com/2009/03/genie-support.html

Your feedbacks are welcome!

Start the IDE again, and open your project.
Now right-click main.vala, and choose "add".
There add "main.gs".
And delete "main.vala" with a rightclick.
It still is listed, as you just renamed it, but it still is shown, as the IDE uses a internal filelist, to manage projects.
At this point, the IDE crashes.
It still is somewhat buggy Sad


I have fixed this bug in trunk.

fantastique, merci beaucoup Exclamation Very Happy
I will compile and package it this evening, must sleep first.

Just wrote my first "real" Genie program Smile
http://www.murga-linux.com/puppy/viewtopic.php?p=286241#286241

We certainly will request more features in future.
I am certain, that Genie/Vala and ValaIDE will become a very important part in Puppylinux.
