Hi,
Yes, this really is the problem. In order to parse and identify a
function/handler 100% correctly you need to do most (if not all) of the
work of the TranScript Parser in the Script Compiler. In the past I've
written any number of language parsers and I know it is non-trivial to
get it 100% right. The best solution IMO would be to add code to RunRev
that allows the script to find out if a handler/function is defined or
not. One way would be to add a function that checks for the existence of
a hanlder/function (without looking at the text of the script), another
would be to hold an array of functions/handlers as a property of the
Object.
Back in my Hypercard days I had a large project that included a script
locator handler. I bypassed all of the issues of parsing for actual
handlers by adding metadata as comments in a consistent format at the
top of each handler. This was then very simple to extract.
Just food for thought.
