If the integral use of C/C++ via Borland or MS can be figured out by Protel
or person X (I too have little time to play, but do have C++ Builder and
have a need to provide scripting automation for myself and my small
company), then great and simple joy could be had by ALL Protel users...
If it's C (or C++(Builder), a la Borland or MS) I can then justify spending
the time that I wish to integrate PERL into Protel.... PERL is great for
quick throw away scripts and full blown application scripts.... it's pattern
matching and regular expressions (albeit that look like modem line noise,
but simple once the cryptic-ness is understood) are invaluable and extremely
FAST to implement. They are so invaluable, that Borland's C++ Builder
implements them as PCRE (PERL compatible regular expressions)... although, I
have not been successful, or had the time to debug them... if it were PERL,
they would just work, and I would be done and not have to worry about the
intricacies of C memory usage and syntax.... end of story....
Anyway, to embed PERL into one's application (a proposed Protel server
add-on in this case), it typically takes a few lines of C code provided by
PERL... of course, I would have to play with PERL's XS to provide some hooks
into the Protel API, but hey, that's another story for another day and
another group... it would be like having another interpreter/compiler like
Client Basic, built into Protel... if you know (or even have a passing
knowledge of) C or the UNIX C shell (nothing too magical about the shell),
then you can write PERL.... except that PERL is way easier than C in that
you don't have to worry about memory, garbage collection, and the PERL
syntax handles lists natively without having to worry about going off the
end of your array!
Cheers,

Just use C++ Builder. It will compile Delphi code and uses the VCL by
default. Best described as a C++ version of Delphi!
It will automatically generate C++ headers for VCL based delphi
classes/units.
