Re: object oriented implementations of rec. descent parsers

Look at PCCTS. It's a parser generator (ANTLR) that creates a
recursive-descent parser (readble, too) in which each rule is a method
in the parser's class.


If you define action code in terms of calls to other methods in the
class, you could subclass the parser, overriding the "action methods"
to perform different actions during the parse, such as compiling,
pretty-printing, and other types of analysis and if the sentence gets
any longer I'll burst!


Look at

for some good pointers to PCCTS stuff.
Also look at newsgroup comp.compilers.tools.pccts.
