Okay, I have a question. BTW, I have been on this list for years now,
and this is probably my first question. And, I have read all of the
documentation many times, and I have searched the archives many times
for the answer. I believe the problem is, I am not sure of the correct
terminology to use for searches, thus leading to my inability to find
the information.
I have an application I'm working on, and in it, I have a text editor
to allow editing of source code (no, it's not a currently-used
language). What is the technique for colorizing the syntactical
representation for the programming language (visually, of course, not
stored in the actual file)? For example, when I am editing an
objective-c file in Xcode, it colorizes the keywords and macro
definitions, etc. according to a particular coloring scheme. Is this
modification of the visual representation of the source code part of
the (Objective-C) Cocoa framework somewhere in one of the text classes,
or is this something Xcode does internally, which would require
re-implementation completely in order for it to work? I have read all
of the Objective-C documentation for text-based applications and
classes, and I'm sure the technique is in there somewhere, I just don't
quite fully understand the terminology used in the documentation. I
have eliminated such things as NSInputServer, etc., and I am sure it's
a delegate function from one of the other text classes, but it eludes
me! Please help.

P.S. I get this as a digest, so I won't see a reply for a while.
