| Is it possible to do something similar in Ada?
| Something like (forgive my fractured pseudo-Ada syntax) -
|
| apple: aliased String(5) := "apple";
| orange: aliased String(6) := "orange";
| pear: aliased String(4) := "pear";
|
| type StringPtr is access String(<>);
|
| fruits: StringPtr[1..3] := (apple'access, orange'access, pear'access);
This is one of the unappealing alternatives I was talking about.
In Ada 95, one would have to write something like:
Fruit_001: constant aliased String := "Apple";
Fruit_002: constant aliased String := "Orange";
Fruit_003: constant aliased String := "Pear";
...
type String_Sight is access constant String;
Fruits: constant array (Positive range <>) of String_Sight :=
(Fruit_001'Access, Fruit_002'Access, Fruit_003'Access, ...);
Whereas with ragged arrays, one need only write:
Fruits: constant array (Positive range <>) of String :=
("Apple", "Orange", "Pear", ...);
Much simpler and clearer, don't you think?
