Re: [Vala] Global int variable.. Problems?
Probably 'index' is already defined as a function or variable in some header.
In fact if you put all the code in a namespace, it compiles with no errors.
Regards,
Davide
int index;
public int main(string[] args)
{
stdout.printf(Ran program: %i,index);
return 0;
}
I get the following errors:
default/main.c:13: error: ‘index’ redeclared as different kind of symbol
default/main.c:14: error: ‘index’ redeclared as different kind of symbol
So I checked the C file, which contains the following:
extern gint index;
gint index = 0;
This is what's throwing the C compiler off... Anybody have a suggestion?

[Vala] dsync - simple rsync frontend
i have written a very stupid frontend for rsync. it's just a few hours work.. This is something I always wanted to have a program like this to sync a directory between different boxes. I'm actually using it in my n900 and laptop syncing info to an http directory on a server. If you wanna give a try: http://lolcathost.org/b/dsync.tar.gz And the n900 binary: http://lolcathost.org/b/dsync (wget + chmod+x) It's written in Genie, and the code could be better, but it's just a quick hack :P I have a list of ideas to do to support different profiles, sincronize configurations, select directories using FileChooser and others.. but my main idea is to keep it simple with as less buttons and configuration options as possible. PD: How lambdas works in Genie? i didnt managed to use them because of syntax errors.

[Vala] array declaration
I have noticed that if you declare an array in a wrong way you get
errors from the C compiler
instead of handling it at vala level.
should this syntax be supported? or we should just throw an error?
Here's the test case:
$ cat a.vala
#!/usr/bin/vala
void main () {
// uint8[] foo = new uint8[16]; // OK
uint8 foo[] = new uint8[16]; // FAIL
print(%d\n, foo[0]);
}
$ vala a.vala
/tmp/a.vala.LDAGFV.c: In function '_vala_main':
/tmp/a.vala.LDAGFV.c:16:9: error: array size missing in '_tmp0_'
/tmp/a.vala.LDAGFV.c:19:9: error: array size missing in 'foo'
/tmp/a.vala.LDAGFV.c:20:16: error: incompatible types when assigning to

Re: [Vala] array declaration
Hey,
Coming from a C++ background I first tried typeHere nameHere[]; too.
I noticed that newer languages seemed to have type[] name; configuration
(Java, C# etc).
I'm not part of the Vala team though, so I dont know the official status!

Vala supports two types of arrays:
1) dynamically heap-allocated arrays:
Vala, Java, C#: int[] a = new int[5];
C++: int* a = new int[5];
C: int* a = malloc (5 * sizeof (int));
2) inline/stack-allocated fixed-size arrays:
Vala: int a[5];
C++: int a[5];
C: int a[5];
Java: not supported
C#: unsafe { int* a = stackalloc int[5]; }
@pancake: 'new' combined with the latter type of array does not make
sense, since the 'new' keyword stands for dynamic alloation on the
heap. The Vala compiler should refuse to compile something like
'int a[] = new int[5]'. So it's obviously a bug.

Any chance you'd compile with valac --save-temps your files etc here?
And then maybe post line 113 from your test.c file so we can see what's
