I'm attempting a 64 bit port of DWT and I'd like some feedback
on API changes.
My initial preference was no changes to existing API in order
to ease future updates from SWT proper. But of course that
requires casts and I suspect they will bubble to the surface
and be exposed to end-users of DWT.
So now I'm leaning towards API changes of this sort:
/// Extension to String
public int indexOf( in char[] str,
char searched,
int fromIndex
){cast(int)...cast(int)...}
becomes
/// Extension to String
public ptrdiff_t indexOf( in char[] str,
char searched,
ptrdiff_t fromIndex) {...}
This maintains sign compatibility with the original API but may
require some changes to existing code. For example:
---
// Fails 64 bit, works 32 bit
int idx = indexOf("astring", 't', 1);
// Works 64 bit, Fails 32 bit
long idx = indexOf("astring", 't', 1);
// Works 64 bit and 32 bit
auto idx = indexOf("astring", 't', 1);
----
Does anyone have an alternative preferred approach to portable
32/64 bit code?
One possibility is separate code bases for 32 and 64 bit, as
per SWT proper. This is not my preference but I am happy to do
it if people feel it would be better this way.

Hi ed,
How is this going? Where is the source code? Would you like
some help?
