PostPosted: Thu 12 Mar 2009, 08:41    Post subject:  Vala and Genie programming  
In my desperate and futile attempts to program
I have been exploring the vala/genie programming language
used in Woof

http://live.gnome.org/Genie

I have been able to compile some of Barrys examples
http://puppylinux.com/genie/

now this:

Code:
init
   a:array of string = {"abc", "def", "xyz"}
   for s in a
      print(s)


gives me

Quote:
# valac v5.gs
v5.c: In function '_main':
v5.c:34: error: stray '\' in program
v5.c:34:40: warning: missing terminating " character
v5.c:34: error: missing terminating " character
v5.c:34: error: 'n' undeclared (first use in this function)
v5.c:34: error: (Each undeclared identifier is reported only once
v5.c:34: error: for each function it appears in.)
v5.c:35: error: expected ')' before '_tmp2'
v5.c:37: error: expected ')' before '}' token
v5.c:37: error: expected ';' before '}' token
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)
#


which is more errors then I can cope with . . . Confused
I am pretty sure it is something to do with the tab
ending the program (python does this too)
but can not solve it.

HELP!

be sure to use tabs, not spaces in the beginning of the lines.

I just copied your example via copy&paste in Opera to leafpad, and it compiles fine here (newyearspup02 with devx).

you also may compile:
valac -C v5.gs

This just creates v5.c and v5.h.
Pleae copy&paste them here.

Maybe the difference to mine show, what goes wrong for you.

Shocked

tried in leafpad
will have another go
- it is the space thing - yes
I am using 4.2 rc2
and a 64 bit processor
(and I am stupid)

v5.c

Code:
#include "v5.h"




static void _vala_array_free (gpointer array, gint array_length, GDestroyNotify destroy_func);



void _main (char** args, int args_length1) {
   char** _tmp1;
   gint a_size;
   gint a_length1;
   char** _tmp0;
   char** a;
   _tmp1 = NULL;
   _tmp0 = NULL;
   a = (_tmp1 = (_tmp0 = g_new0 (char*, 3 + 1), _tmp0[0] = g_strdup ("abc"), _tmp0[1] = g_strdup ("def"), _tmp0[2] = g_strdup ("xyz"), _tmp0), a_length1 = 3, a_size = a_length1, _tmp1);
   {
      char** s_collection;
      int s_collection_length1;
      int s_it;
      s_collection = a;
      s_collection_length1 = a_length1;
      for (s_it = 0; s_it < a_length1; s_it = s_it + 1) {
         const char* _tmp3;
         char* s;
         _tmp3 = NULL;
         s = (_tmp3 = s_collection[s_it], (_tmp3 == NULL) ? NULL : g_strdup (_tmp3));
         {
            char* _tmp2;
            _tmp2 = NULL;
            g_print (_tmp2 = g_strconcat (s, \n", NULL));
            _tmp2 = (g_free (_tmp2), NULL);
            s = (g_free (s), NULL);
         }
      }
   }
   a = (_vala_array_free (a, a_length1, (GDestroyNotify) g_free), NULL);
}


int main (int argc, char ** argv) {
   g_type_init ();
   _main (argv, argc);
   return 0;
}


static void _vala_array_free (gpointer array, gint array_length, GDestroyNotify destroy_func) {
   if ((array != NULL) && (destroy_func != NULL)) {
      int i;
      for (i = 0; i < array_length; i = i + 1) {
         if (((gpointer*) array)[i] != NULL) {
            destroy_func (((gpointer*) array)[i]);
         }
      }
   }
   g_free (array);
}


and v5.h

Code:
#ifndef __V5_H__
#define __V5_H__

#include <glib.h>
#include <glib-object.h>
#include <stdlib.h>
#include <string.h>

G_BEGIN_DECLS



void _main (char** args, int args_length1);


G_END_DECLS

#endif



Thanks Mark Smile

Lob,

I get the same error trying to compile it in WinowsXP, using 0.5.7.

At home in Puppy I had used 0.5.1:
http://distro.ibiblio.org/pub/linux/distributions/puppylinux/pet_packages-4/vala-0.5.1-i486.pet

The problem is the generated C code, line 34:


Code:
            g_print (_tmp2 = g_strconcat (s, \n", NULL));
should be:

Code:
            g_print (_tmp2 = g_strconcat (s, "\n", NULL));

So there missed a quotation mark.

Maybe with 0.5.1 you will have success.
Mark

yes, with 0.5.1 the example compiles fine also in WinXP.
In 0.5.6 it does not.
So this is a bug in newer versions, or the syntax for the "for" loop changed.

Thanks Mark Smile

You can use the random method from GLib.
http://valadoc.org/?pkg=glib-2.0&element=GLib.Random


Example:
Code:
init

   // return a random value from 1 to 9
   a:int
   a = GLib.Random.int_range(1,10)
   print("%d" , a)

I attach a pet made from the Archlinux package of the vala-IDE.
http://www.valaide.org/doku.php

It requires Gtksourceview:
http://dotpups.de/puppy3/dotpups/Libraries/Gnome-2.19.2-libs/other-Libs/gtksourceview-2.0.2-i486.pet

I did not try, if it works in Puppy.
I tested it in NYP 02rc7, that has updated Gtk libraries (based on Ultrapup).

The homepage says, it requires vala 0.5.7, but it seems to work fine with 0.5.1.

Hey Mark,

Thanks for the random prog - got that working ok Smile

I am using it to train an infinite number of monkeys on virtual typewriters to write this (to start with)

Code:
while myLine != "in the"   


Soon (a few billion years) they will type out the Bible and the Complete Works of Shakespeare

. . . what am I missing?

Code:
// Infinite Monkey Theorem, Lobster and Shadow, March 2009
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"}
   myLine:string = ""
   myCount:int = 6
   while myLine != "in the"
      for i:int = 1 to myCount
         myLine = myLine.concat(myChars[GLib.Random.int_range(0,myChars.length)])
      print(myLine)


rather than using a string array - is there not some sort of more efficient string pointer?

Lobster, sorry no answer, but a request:
please do not edit your messages to add new content.
I just saw your monkey example by accident, when I looked up something in this thread.
That also had happened before, so that I replied very late.

The best is to add a new message, so that I can see it in my "View posts since last visit".

Mark
