But, I am hoping to modify the FPC parser/tokenizer so that instead
of it deciding whether to stop, it should do a callback and let the
caller decide whether it should stop.
Is this likely to be unworthy of the effort?
No, but it is hard to do in a meaningful way.
Could you (or someone else) point me to the source files of FPC
parser/tokenizer please.
Most units that are related to parsing are inside "compiler" directory
and prefixed with a "p", e.g. pdecl.pas and pdecsub.pas (but you still
need to find the relations between those units yourself - I myself only
find these "on demand" ^^)
I can guess that it won't be easy; but if it can be done, I think it
should be.
It is the only way the code formatter can keep up with new features of FPC.
I don't think that it will be that easy. You might need to do so many
changes that you can't simply copy new features from the compiler to
your formatter.
You might be better of playing around and modifying the parser in
fcl-passrc - at least that one was developed for simply parsing Pascal
code. You might be able to extend it with better error recovery and
fragment parsing. (Before you start yet another Pascal parser, because a
"forked" FPC parser might become to different to be recognized as FPC's
parser any more)

Sven
