Scott,
Thanks again for your help (I was already planning on buying your book
the next time I had any money).
Now, it is pretty clear the most the old NeXT PostScript functions (eg
PSthis(), PSthat()) have been incorporated into the NSBezierPath class.
There are only a few a classes used, and most of them are obvious to
decipher (eg NXThis -> NSThis).
However, it is not yet clear what the type NXCoord represents? (A pair
of NSPoints?) Apparently this type was defined in the old
<appkit/Form.h> .
The other thing that is now on my radar is the NeXT class "UserPath."
According, to its head this class has a "set of rountines [that] manage
he allocation and growth of the operator and operand arrays, as well as
the calculation of the bounding box." This class set itself in its own
memory zone and to be drawing related. So, I suspect that "UserPath"
is obsolete is Cocoa, but I am not sure?
Truly Yours,
John Anderson

Oleg,
I guess that I will take the lead on the source-code "Rosetta-stone"
facet of the project.
I think that we may need to just start by identifying which NeXT
classes, methods and functions do not in Cocoa.
To start with:
NXStream -> NSPipe???
Nope.. NXStream was a stream class that allowed you to read and write
from a disk file. There is no equivalent in Cocoa.
Aside from that... drawing has changed.. you've got NSBezierPath now
instead of the functions... 3.1 had no notion of foundation, or
anything along that line. views, mouse handling are the same..
You may want to look at it more for inspiration design wise rather
than anything concrete code wise.
