Can anyone comment on the level of effort required to port a legacy
application from NextStep to Cocoa? Has anyone does this? I would
very much like to hear about your experiences.
I gather that people have done this in a sort of two-stage process:
(1) Port from NEXTSTEP to OPENSTEP using the porting tools included
with OPENSTEP 4.2 Developer. This gets you an application built
against the AppKit and the FoundationKit.
(2) Port from OPENSTEP to Mac OS X. The AppKit and FoundationKit are
largely unchanged on Mac OS X -- though they are heavily extended --
but you may need to re-create your nib files (or use nibtool to dump
them and re-create them, or something like that). You'll also need
to switch from using things like pswraps and PSxxx() calls for
drawing to using CoreGraphics.
I've thought of getting some source to an old NEXTSTEP application or
two and doing a port going this route, but my only OPENSTEP machine
is a 32MB original NeXTstation with 400MB of disk. Plenty fast for
print serving, pain for software development.
