Great feedback, thanks.
I added several point to
http://wiki.lazarus.freepascal.org/Namespaces#Mapping_Namespace_to_each_search_path
Regarding the following point:
It may be proposed, that if 2 units Utils exists, both must be aliased. Even
though, if only one was aliased, they would have different names already.
Forcing to alias both units might not be a good idea. Consider the
following:
You have a unit that uses Graphics and Windows (which both contain a
type TBitmap).
uses
Windows, Graphics;
(...)
var
b: TBitmap;
bm: Graphics.TBitmap; // I don't remember FPC's current order of
resolution, but in this example Windows takes precedence over Graphics
You use the prefixed Graphics.TBitmap in quite a few locations in that unit.
Now you add a new package that has also some nice graphic routines (but
no TBitmap for the sake of example ^^) that also reside in a unit graphics.
uses
Windows, Graphics, Graphics in GraphicsPkg as PkgGraphics; // I just
picked one of the syntaxes... no need to discuss this here ^^
Now if you force that both units are aliased you'd need to change all
references of Graphics.TBitmap to e.g. LCLGraphics.TBitmap. While this
can be done in an IDE or with Find & Replace I'd prefer that this is not
needed, cause it's simply an unneccessary change.
Regards,
Sven
