Does anyone have an Emacs mode implementation for Ada that they
are willing to share?

Allocation question

[Olivier Scalbert]

Hello,

I have write a small package:

---------------------------------------------------
-- ads
---------------------------------------------------
package Image is

     type Color_T is record
         Red:   Integer;
         Green: Integer;
         Blue:  Integer;
     end record;

     type Image_T is array(Positive range <>, Positive range <>) of Color_T;

     procedure Fill(Image: in out Image_T; Color: Color_T);

end Image;

---------------------------------------------------
-- adb
---------------------------------------------------
package body Image is

procedure Fill(Image: in out Image_T; Color: Color_T) is
begin
      for x in Image'range(1) loop
          for y in Image'range(2) loop
              Image(x,y) := Color;
          end loop;
      end loop;
end Fill;

end Image;


---------------------------------------------------
-- test
---------------------------------------------------
with Image;
use Image;

procedure Test_Image is
     Image : Image_T(1..100, 1..100);
     FillColor : constant Color_T := (0, 0, 0);
begin
     Fill(Image, FillColor);
end Test_Image;


This program seems to work.
However when I increase the size of Image, I get a Segmentation fault.

Should I need to play with access type and allocation stuff ?

Thanks,

Olivier

I would sugges that you rather wrote this:

   Image := (others => (others => Color));

It is a more precise expression of what (I guess) you want done, and
thus it gives the compiler more precise information to work with.

Greetings,

Jacob

This used to be much more true than it is now, unfortunately. I keep
running into people at work who "just use GEdit". Sigh.

I've been using Emacs as my main IDE both at home and at work since
2000, adding email and other things a couple of years later, and have
no plans of changing. One day I might even become a member of the
Church of Emacs :)
