Hello All
Not sure whether this is the right forum for this question - please excuse
and point me in the right direction if I'm wrong.
I have been playing with Moose 4.8, downloaded last October, mainly because
I am interested in PetitParser. I have been constructing fairly trivial
parsers to get to understand the system. I took as an example a typical HTML
tag, i.e. any text enclosed in angle brackets <>. My first attempt was:
($< asParser, $> asParser not star, $> asParser).
This seemed to send the parser into a loop, except in the case where there
was no text between the brackets. Floundering around, I tried:
($< asParser, (PPPredicateObjectParser anyExceptAnyOf: '>') star, $>
asParser).
This worked as expected, but I was not happy with the apparent clumsiness of
the middle term. So I tried:
($< asParser, (PPPredicateObjectParser char: $>) not star, $> asParser).
This again sent the parser into a loop.
It looks as though I have some fundamental misunderstanding of the function
of 'not' in a parser, or else it is not working as specified. Could someone
kindly explain to an inquisitive idiot what is going wrong?
Many thanks in advance
Peter Kenny
