Mike,
Thanks for the enlightenment - a very interesting presentation. I (like
many others) am looking forward to exploring the code when it becomes
public.
At first glance, adapting parts of NetRexx to an Eclipse editor may not be
too bad and I see some similarity to what I did with the PL/I editor. The
NetRexx parse control and clause parsers may be similar to a JavaCC
generated recursive descent (LL) parser.
I agree that tokenizing is not a significant problem - I used a JFlex (DFA)
scanner for PL/I because of the hundreds of keywords but that is not
necessary with NetRexx.
The editor needs to process incrementally (for responsiveness) and report
any errors up through the translation phase, but NetRexx (as I currently
understand it) is structured as a batch oriented interpreter. The
challenge will be fully understanding all the NetRexx interfaces and
internal data structures to determine what (if anything) can be effectively
used in an incremental editing environment.
