How to manually parse a floating point number from a string
Of course most languages have library functions for this, but suppose I want to do it myself. Suppose that the float is given like in a C or Java program (except for the 'f' or 'd' suffix), for example "4.2e1", ".42e2" or simply "42". In general, we have the "integer part" before the decimal point, the "fractional part" after the decima...

What is the inversion of the Shunting Yard algorithm?
Dijkstra's Shunting Yard algorithm is used to parse an infix notation and generate RPN output. I am looking for the opposite, a way to turn RPN into highschool-math-class style infix notation, in order to represent RPN expressions from a database to lay users in an understandable way. Please save your time and don't cook up the algorit...

Abstract Syntax Tree
I have an AST derived from the ANTLR Parser Generator for Java. What I want to do is somehow construct a control flow graph of the source code, where each statement or expression is a unique Node. I understand there must be some recursiveness to this identification, I was wondering what you would suggest as the best option and if ANTLR h...

Python implementation of Parsec?
I recently wrote a parser in Python using Ply (it's a python reimplementation of yacc). When I was almost done with the parser I discovered that the grammar I need to parse requires me to do some look up during parsing to inform the lexer. Without doing a look up to inform the lexer I cannot correctly parse the strings in the language....
