recursive descent parser
anyone have a RDP program that can handle the following grammar?
<elist> -> <elist>,<e>|<e> <e> -> <n>^<e>|<n> <n> -> <n><d>|<d> <d> -> 0|1|2|3|4|5|6|7|8|9
in case you were wondering, this grammar says that something like the following can be taken as an input string.
2^2^3,15,20^2
Re: recursive descent parser
There's the JavaCC, which takes in a grammar like you have and generates Java source-code for a compiler. I believe the algorithm they use is a Recursive Decent Parser, but because of their implementation, left recursion is not allowed.
