In Simple Iterator-based Parsing, ... In the early seventies, Vaughan Pratt published an elegant improvement to recursive-descent in his paper Top-down Operator Precedence. Pratt’s algorithm associates semantics with tokens instead of grammar rules, and uses a simple “binding power” mechanism to handle precedence levels.

I’ll replace this status report with an article about topdown parsing of JSON at a later time. If you’re looking for a production-quality JSON library, get simplejson. If performance is critical, try python-cjson.

We wish to examine the role of context free languages and pushdown automata in translation, compiling, and parsing. ... Note that technically we are no longer designing pushdown machines. Actually we have designed a top-down parser. The difference is that parsers can advance along the input string (or not) as they desire.

The major class of grammars used for top-down parsing is the class of LL(1) grammars. LL(1) means that the parser we build from the grammar is processing the input string from left to right (that's the first L) using leftmost derivations (the second L). This is exactly what the parsers we wish to design shall do.

The parser uses symbol-look-ahead and an approach called top-down parsing without backtracking. Top-down parsers check to see if a string can be generated by a grammar by creating a parse tree starting from the initial symbol and working down.
