I wrote a utility that could do this sort of
thing.

Actually it did simple local textual analysis, then
allocated different colours to keywords, numbers,
procedures, and variables. It guessed what was what
by simply assuming that capitalisation conventions
were being adherred to. Not computer science, but good enough.

The reason for doing this was to make life seem a little
more familiar to a Java user who needed to use BlackBox
for a short while for a specific task.

The point of my email is this: I implemented the above
functions by dropping a 'Wrapper' onto a standard Text.
This worked fine, with the colour coding happening automatically
as you typed. But BlackBox does not really like Wrapped Views.
Firstly the blue diamonds in Trap texts could not find the right
source code lines, then we noticed that the 'F9' file compare
utility does not work with Wrapped Texts.


Is using Wrappers to extend functionality (is this called
'Composition' rather than 'Extension'?) an obsolete/discredited
technique, or have I simply found some bugs in the Trap & F9 routines?


Regards

Robert
