Description xavier.bestel 2007-11-01 21:16:51 UTC 
There's a need for directly embedding fixed-size arrays in struct/class or on the stack. Preferred syntax is:

int[100] myarray;
Comment 1 Jürg Billeter 2007-11-03 20:38:07 UTC 
Yes, this makes sense, in my opinion. It might be a bit problematic grammar-wise for local variables but it should be semantically conflict-free.

*** Bug 522003 has been marked as a duplicate of this bug. ***
Comment 3 Maciej (Matthew) Piechotka 2008-03-15 08:30:25 UTC 
Will it be possible to use int[some_function ()] myarray; for alloca call?
Comment 4 Arc Riley 2009-03-24 14:53:57 UTC 
I've hit this problem as well.

The lack of fixed-size stack arrays is a language deficiency that should be solved soon.  It should not be impossible to cause Vala to generate basic C syntax such as "float Quaternion[4];".

    Arrays: Add experimental support for fixed-length arrays
    
    Local fixed-length arrays are allocated on the stack.
    
        int[3] array = { 1, 2, 3 };
    
    Fixes bug 492481.
