Hello,


I'm looking for parsing techniques to handle expressions that include
user defined operators and overloaded operators. The precedence
levels of operators are user definable over a range of several hundred
values. The associativity is user definable as well. Any pointers to
books or articles are more than welcome.


Thanks in advance,
Roy Germon
[It shouldn't be hard to concoct an operator precedence parser that can
do that, but I don't think it's a very good idea. User extensible syntax
was fashionable 20 years ago but now nobody bothers because it's so
phenomenally confusing. Look what a tangle you can get into with C++,
just by changing the semantics to fixed syntax. -John]
