Just the number of existing Pascal parsers suggests to me that time is spent
*better* in a front-end unification, than in maintaining and synchronizing
any number of independent parsers.
That is why FPC provides one in fpc-passrc: so other people will not
try to re-invent the wheel.
It is currently used in 3 projects
- fpdoc
- WST to generate interface descriptions
- A project I am working on to convert pascal code to JavaScript.
(see also the fcl-js sources)
This is also the reason I contracted Matthias to extend fcl-passrc.
All in all, I think it would be to everyones advantage if we could
concentrate on fcl-passrc. It is by far the most compatible engine
out there, and is sure to remain maintained (for fpdoc) and extended
whenever the compiler is extended.
I think this is a far more realistic scheme than trying to extract
the scanner/parser from the compiler.
Michael.
