During the last period I experimented a bit with (APFL) Ghostscript and
discovered that Ghostscript can be build as a framework on OSX,
moreover it has a nice API which allow programs like MacGhostView or GV
to interact directly with the interpreter and to send PS to a bitmap
device for on-screen rendering. I have a small example of an
interactive interpreter running with Cocoa.
I was thinking to add direct PS rendening to TeXniscope using the
Ghostscript framework. This has to wait that I have some spare time to
dedicate to programming.
Even if PS is to be considered an obsolete format (for document
exchange), it still happens to me frequently to have to deal with PS
files (people in the linux world still stick to it) so I agree that OSX
need a good PS viewer. Apple support for PS is not at the level of
other features, surely it can be done better.
