Like Matt suggested you can start with his simple vbscript to
perlscript converter, but I would recommend to do a really
complete job that you use a full on grammar and something
like Parse::Yapp to do the parse tree. I personally would
find this approach the most enjoyable, but it may be that
the parse times that result from this are too slow, and you
might need to take the approach that Matt did and brute
force your way through the code to render to perlscript.
I have not started on this, and likely would not for a while
yet so feel free to have at it. If you decomped this
functionality into a module like Parse::VBScript or
some such ( I don't know about this CPAN namespace ) and
presented an interface like:
my $vbparser = Parse::VBScript->new($string_ref);
my $perlscript_ref = $vbparser->perlscript();
this interface would allow me to use your code from
Apache::ASP easily by passing the VBScript code into
the parser, and get the equivalent perlscript. The
passing by ref would just save on some of the string
copying that may be unnecessary otherwise.
There is a HUGE need for this vbscript emulation, and this
would greatly add to the functionality of Apache::ASP, so
many thanks ahead of time!
