Pratt parser
In computer science, a Pratt parser is an improved recursive descent parser that associates semantics with tokens instead of grammar rules.[1] It was first described by Vaughan Pratt in the 1973 paper "Top down operator precedence",[2] and was treated in much more depth in a Masters Thesis under his supervision.[3] Pratt designed the parser originally to implement the CGOL programming language. Douglas Crockford used the technique to build JSLint.[4]
