the isolated test case is in the mail
for the grammar, I am afraid this will be difficult.
It is not my grammar but the postgres sql one that Anne and Olivier are
creating.
It is their first grammar and despite their best efforts, it shows
(without blaming anyone, we all know how difficult it can be to create a
full-fledged grammar, and frankly full postgres is proving far more
complex that I would have ever thought)
I am trying to rationalise and simplify their grammar to understand
these problems
If that is not possible, did you try debugging with
the PetitParser Debugger?
Yes, but it does not simplify enough the process of
debugging petit
parser rules in this case
I got lost

First 3 tests pass, last one fails
But the grammar says:
---
condition
^ expression

Can anyone propose an explanation?
[Notes:
Yes I checked that I am testing the right grammar
Yes the 'true)' test is strange, but this is precisely what I am trying to debug
(why does it pass for #condition ?)
